A method for tracking, in a roaming receiver, RF channels in a multi-area system where each area has a unique RF channel and each unique RF channel has a unique address for each user. A plurality of telephone area codes are stored into a memory of the receiver with each of the telephone area codes corresponding to a different RF channel within the multi-area system. An address from the RF channel which is unique to the receiver for that specific RF channel is received by the receiver, each address corresponding to one of the stored telephone area codes. A telephone area code corresponding to the address is then retrieved from the receiver memory, and the telephone area code is displayed in a receiver display to allow a user to quickly recognize which area of the multi-area system the receiver is located within.

A motor vehicle vibrating system vibrates a motor vehicle having front and rear axles rotatably supported on a motor vehicle frame to simulate the load which would be applied from an actual road to the motor vehicle. The motor vehicle vibrating system has a first vibrator for vertically vibrating the rear axle, a second vibrator for vertically vibrating the front axle, and a third vibrator for vibrating one of the front and rear axles back and forth in a longitudinal direction of the motor vehicle.

A thin film forming device comprises a vacuum chamber which is vacuous inside, a substrate holder which is provided in the vacuum chamber for holding a substrate thereon and a molecular beam source disposed in the vacuum chamber directed toward the substrate holder. An endoscope is inserted in the vacuum chamber at the tip end thereof and is covered by a transparent protecting tube connected to the tip end of a bellows. As the bellows is stretched or retracted, the tip end portion of the endoscope and the protecting tube can be advanced to a space between the substrate held by the substrate holder and the molecular beam source or retracted into a shelter provided at a side of the space. As a result, it is possible to know the composition of a thin film as well as to observe the irradiation source of material of the thin film and the plasma radiation while the film is being formed on the film-forming surface of the substrate in the vacuum chamber.

In an image forming apparatus capable of reading a book document while turning over pages of the book, image data representative of two spread pages of a book document are stored in a frame memory. Among the image data, image data matching the front of a sheet are read out of the frame memory first and then output on the front of a fresh sheet. Then, an image is formed on the rear of a sheet refed from a duplex copy tray or refeed tray. Alternatively, an arrangement may be made such that, among two pages of image data, the image data read last are out of the frame memory first and then output on the front of a fresh sheet, and then an image is formed on the rear of a sheet refed from the refeed tray.

The PLL circuit provides both the advantages of analog phase control, in which a good C/N ratio can be realized, and the advantages of digital phase control, in which broad-band lock can be performed. A multi-channel FM receiving method and apparatus are able to utilize the PLL circuit to reduce the influence of the leakage occurring among input signals and suppress image disturbance. One PLL circuit includes: a VCO; a pre-scaler for dividing a feedback signal obtained from the VCO; a first distributor for distributing the feedback signal to send first and second digital feedback signals; a second distributor for distributing a reference signal to send a digital reference signal and an analog reference signal; a digital phase comparator for comparing the digital reference signal and the first digital feedback signal with each other to send a digital phase error signal; a charge pump; a mixer for adding the digital phase error signal to an analog phase error signal, which is obtained by comparing the analog reference signal with the second digital feedback signal to send a composite phase error signal; and a low-pass filter for eliminating high frequency components from the composite phase error signal to input the resultant signal to the VCO.

An image forming apparatus including an image reading unit for reading an original and for outputting image data corresponding to the original, an image processing unit for processing the image data supplied from the image reading unit in accordance with a predetermined method and for outputting printing image data, a printer unit for printing an image corresponding to the printing image data supplied from the image processing unit, and an image adding unit for adding an identification information to the recording sheet on which the image is formed by the printer unit, the identification information identifying the image forming apparatus in order to prevent forgery of securities, confidential documents or backnotes. A detector detects the presence or absence of the image adding unit and disables the copying functions when the image adding unit is absent.
摘要:
A system of adding an operand address included in an instruction word to the contents of a modification register to obtain an effective address, wherein address data which designates each of a plurality of data tables constituted with prescribed storage capacity, is stored in a plurality of modification registers. Prescribed address data of one of the plurality of modification registers is selected based on the instruction word. The effective address for addressing the operand is obtained by adding the prescribed address data of the one of the plurality of modification registers to address data included in the operand address. The address data included in the operand address designates addresses which correspond to addresses of the plurality of data tables.

A recording and reproducing apparatus is to monitor the information to be recorded actually by the recording heads. The recording and reproducing apparatus comprises a digital mixer for inputting signals from the multiple preceding reproducing heads corresponding to the multiple recording tracks respectively and performing the prescribed signal processes and simultaneously outputting the signals inputted to the monitor speaker, and cross fader circuits for shifting signals from the digital mixer or the multiple preceding reproducing heads and outputting to the recording heads placed on the back of the preceding reproducing heads, and which is adapted to rewrite the information recorded on the first recording track of the recording medium to the second recording track. The signals outputted from the preceding reproducing heads or the signals outputted from the cross fader circuits to the recording heads is shifted every multiple recording tracks and inputted to the digital mixer and thus by means of monitoring the signals outputted to the recording heads by the speaker for monitor, the record information to be actually rewrote can be monitored.

A finisher operable with an image forming apparatus for discharging paper sheets coming out of the apparatus and each carrying an image thereon to a plurality of bins while sorting the paper sheets and, if desired, packaging the paper sheets in an envelope. When a pack mode is selected, the size of paper sheets and the sizes of envelopes which are to be fed from a paper cassette or a tray each are sensed by size sensors. Envelopes sizes capable of accommodating the paper sheets of the sensed size are determined and compared with the sensed envelope sizes. Among the determined envelope sizes, the envelope size capable of accommodating the paper sheets of the size sensed by the size sensor in a desired number inputted. When the desired number is too great to be packaged in the envelope, such an occurrence is displayed and/or the pack mode is cancelled.

Disclosed is a porous polyethylene hollow fiber membrane of large pore diameter which have (a) rectangular pores formed by microfibrils that are oriented in the lengthwise direction of the fibers and joint portions that are composed of stacked lamellae, the pores being contiguous with each other from the inner wall surface to the outer wall surface of the hollow fiber membrane to form a stacked, multicellular structure, (b) an average pore diameter ranging from greater than 2 .mu.m up to 10 .mu.m as measured with a mercury porosimeter, (c) a porosity of 75 to 95%, and (d) an air permeability of not less than 8.times.10.sup.5 l/m.sup.2 .multidot.hr.multidot.0.5 atm. This hollow fiber membrane can be produced by melt-spinning polyethylene, annealing the resulting unstretched hollow fiber under specific conditions, and then cold-stretching and hot-stretching the annealed hollow fiber under specific conditions.
