摘要:
In a personal communication system in which a call is originated from a calling side terminal equipment using number information allocated to a called person and the call is processed on the called side terminal equipment as a personal call, the system comprises: a transfer requesting section disposed on the called side terminal equipment, for transmitting a transfer request signal to the calling side terminal equipment when a predetermined transfer request is inputted during a processing of the personal call; and a notifying section disposed on the calling side terminal unit, for notifying the calling person that transferring the personal call is requested. Therefore, when a personal call is incoming, if the designated specific called person is absent, the calling person can recognize the absence of the called person and then select cancellation of the personal call, proxy answer by another person, or transfer of the personal call, according to the calling person's will.

In a time-division multiplex transmission system, a host machine (3) and a plurality of addressable terminals (51 to 56) are connected together by way of a signal line (6). The same address (A) is assigned to a group of the terminals (51 to 54) so that the group of terminals (51 to 54) may be placed under control at the same time upon receipt of a transmission signal (SS) from the host machine (3). Reply signals (RS1 to RS4) from the respective terminals (51 to 54) are adjusted so that they are sent back at different points in time. This enables the host machine (3) to determine which of the terminals sent back the reply signal (RS1 to RS4).

A device which can support a determination of a camera layout by automatically preparing the camera layout that satisfies a customer request based on the customer request including a surveillance layout. Specifically, a need table that is a data set of a plurality of arrangement candidate cameras satisfying the customer request is prepared from the customer request including the surveillance layout. An arrangement of the plurality of the arrangement candidate cameras on a map is calculated based on the need table using a clustering method and a temporary layout of cameras is prepared. Then, an arrangement layout of the cameras in the surveillance layout is determined based on the temporary layout.

A radio communication system minimizes power consumption against noises. The system includes a first radio terminal (10A) with a first transmitter (40A) for transmitting a first data indicative of a specific event, and a second radio terminal (40A) with a battery (14B) and a receiver (20B). The first radio terminal (10A) includes a first bit interpolator (32A) which inserts a check bit pattern of “01010101” at a predetermined cycle into one frame of the first data. The second radio terminal (10B) has a second power controller (60B) which intermittently activates the second receiver (20B) at predetermined intervals in order to receive the bit-interpolated data from the first transmitter. A check bit detector (24B) is included in the second radio terminal (10B) to detect the check bit pattern from within the bit interpolated data and to issue a stop signal immediately upon occurrence of that the check bit pattern fails to appear at said predetermined cycle within a predetermined time frame shorter than one frame length of the first data. In response to the stop signal, the power controller of the second radio terminal terminates a current receiving operation.

This antenna unit is adapted to be connected to an electronic device for transmitting a received radio signal to the electronic device. The antenna unit comprises a noise canceller for canceling noise generated in the electronic device and transmitted to the antenna unit through a ground line. The noise canceller is a conductive stub piece one end of which is electrically connected to an electromagnetic shield of the antenna unit and the other end of which is a free end. The stub piece has a length of about ¼ of a wavelength of the radio signal.

Provided are a propylene resin composition comprising 100 parts byweight in total of two different types of propylene polymers each having specific properties, from 0 to 50 parts by weight of a specific elastomer, and from 0 to 50 parts by weight of an inorganic filler; and a method for producing it. The production method comprises melting and kneading two polymer groups each comprising one or more propylene polymers. The resin composition in which the viscosity difference between the propylene homopolymer segments to form the base polymer and the amorphous propylene segments to form the disperse phase is small is produced by first melting and kneading one polymer group, then immediately adding the other polymer group thereto, and further kneading and melting the two. For the composition in which the viscosity difference therebetween is large, the polymer groups are separately kneaded in melt, and the resulting melts are further kneaded. The propylene resin composition has high stiffness, high impact resistance and high fluidity, and its moldings have good appearances.

A process for preparing a styrenic resin is herein disclosed which comprises the step of volatilizing extrudinga styrenic polymer (SPS) powder having a syndiotactic configuration in the presence of water, an alcohol or an antioxidant by the use of an extruder to obtain pellets. According to this process, the operation of volatilization extrusion is done in the presence of water, the alcohol or the antioxidant to stably and efficiently prepare the SPS pellets in which yellowing is inhibited, and the operation of the volatilization extrusion is carried out in the presence of water to stably and efficiently prepare the SPS pellets containing a less amount of a remaining volatile component such as an unreacted monomer.
