摘要:
In an image processing apparatus, after a current band of an image has been read, an original is fed at a distance of the upper half band width of the current band. When the next band is read, the current band at the lower half band width is overlappingly read. The band data at the lower half band width of the current band is stored in a memory, and the next band is read. Averaging processing or function processing is applied to the band data which has been overlappingly read.

An information apparatus comprises a main apparatus and a subsidiary apparatus which are separable. The main and subsidiary apparatuses has electrical connectors which are connected substantially automatically when the two apparatuses are attached. The connectors are provided with covers which are movable in association with the attaching procedure. Thereby, the connectors can be kept clean and free from dust contamination or breakage, and the reliability of the information apparatus can be enhanced.

A coordinate input apparatus includes a wireless vibrating input pen for alternately generating a first vibration having a first frequency and a second vibration having a second frequency different from the first frequency. A vibration transmitting member is provided for transmitting the first and second vibrations input from the vibrating input pen by contacting the vibrating input pen. A plurality of vibration detectors are coupled to the vibration transmitting member for detecting the first and second vibrations transmitted through the vibration transmitting member. Processing circuitry is included for deriving at least one coordinate of a position of the vibrating input pen on the transmitting member according to a transmission delay time between the first and second vibrations detected by the vibration detectors. Transmission and reception of timing information between the vibrating input pen and the main body of the apparatus is not required. Hence, it becomes possible to provide a wireless vibrating input pen.

A coordinate input apparatus comprises: a vibration pen to generate a vibration; a vibration propagating plate to propagate the vibration generated by the pen by touching the pen to the plate; vibration sensors to detect the vibration propagated to the plate; a supporting member which supports the plate and whose vibration propagating velocity is slower than the plate; a position coordinate calculating circuit to calculate the position coordinates of the pen on the plate on the basis of the detection signals from the sensors; and a display which is provided below the supporting member and displays the calculated coordinates. The plate is made of metal or transparent glass and the supporting membrr is made of a transparent synthetic resin. The supporting member is directly in contact with the plate at a rough surface, its acoustic impedance value is different from the plate, and its vibration attenuation ratio is larger than that of the plate. Since the vibration wave component propagated to the sensors is not influenced by the interference of the vibration propagated in the support member, the coordinates can be accurately detected on the basis of the vibration detection waveforms without distortion.

The present invention is a method and an apparatus for preventing the entrance of an unmanned dump truck, so that an interference and a collision between the unmanned dump trucks and a working vehicle in the working area are prevented. In the method, an unmanned dump truck (3) enters the working area (91) only when another dump truck (3a) is not in the working area (91) and the working vehicle (92) in the working area (91) issues an entrance permission command. The apparatus includes entrance permission means (22), provided on the working vehicle (92), and computing means (11), for outputting a control command thus permitting the unmanned dump truck (3) to enter only when another dump truck (3a) is not in the working area (91) and an entrance permission command is inputted into the apparatus.

There is provided a coordinates input apparatus in which a vibration input from a vibration pen having a piezoelectric transducer is detected by a plurality of vibration sensors attached to a vibration propagating plates such as an input tablet and the coordinates of this pen on the plate are detected. The tip of the vibration input pen is made of a material of a resin of the polyamideimide system such as thermoplastic polyamideimide or aromatic polyamideimide. With this material, a desired image can be smoothly input to the input tablet without scratching the glass surface thereof and the accurate coordinates can be detected.
摘要:
Vibration applied to a tablet is sensed by a sensor provided on the tablet and a time delay from generation of the vibration to the sensing thereof is measured, whereby distance from the vibration source to the sensor can be measured. If the vicinity of the leading edge of the envelope of registration is sensed when sensing the vibration, the effects of reflected waves from the periphery of the tablet are reduced. To this end, the envelope is differentiated to detect an inflection point. The peak gain frequency of the differentiating circuit is greater than the frequency of vibration generated by the vibration source. As a result, the phase of the output signal produced by the differentiating circuit is advanced by about .pi./2 with respect to the phase of the input signal, thereby making it possible to sense vibration more quickly.
摘要:
A cage for a roller bearing which is free of fretting and abnormal noise, which can be manufactured at low cost, and which can be easily mounted in the bearing. The cage is formed by bending a metal sheet having pockets into a ring shape, temporarily joining its ends, heat-treating the ring thus formed to remove stress, and separating the temporarily joined portion. Such a cage tends to rotate slower than the raceway members on the driving side of the bearing, making it possible to reduce fretting. Such a cage can be used under high-temperature conditions.
