Inventor: HASHIMOTO TADAO
IPC: H04W84/16

Abstract: In a wide area cordless telephone system, an individual-call signal is generated if an incoming call from the telephone network is an individual call to one of cordless stations of a group and a group-call signal is generated if it is directed to all cordless stations of the group. A group of access units are associated with the cordless station of each group to establish a control channel and speech channels with the cordless stations. The access units respond to the individual-call signal by transmitting a speech-channel identifier to one of the cordless stations through the control channel and transmitting a ringing signal through a speech channel specified by the speech-channel identifier. In response to the group-call signal, speech-channel identifiers are successively transmitted from the access units to the cordless stations through the control channel and group ringing signals are respectively sent to the cordless stations through speech channels specified by the speech-channel identifiers. In a modified embodiment, the cordless stations receive pairing identifiers each containing a pair of an access unit identifier and a cordless station identifier and transmit a response containing one pairing identifier that specifies the own station. The access units also receive pairing identifiers from the controller for detecting a match with those received from the cordless stations. If a match is detected by each access unit, it is entitled to send a speech-channel identifier to the cordless station which is specified by the matched identifiers.

Abstract: The present invention provides a positive photo-sensitive resin composition comprising a polybenzoxazole precursor as a base resin, an organic solvent-soluble polymer or its precursor (e.g., a polyamic acid) as a component for imparting improved adhesion, flexibility or heat resistance, and a diazoquinone compound and/or a dihydropyridine compound as a photo-sensitive agent. This photo-sensitive resin composition can form a pattern of high resolution and further has excellent adhesion and mechanical properties. The present invention further provides three novel diazoquinone compounds as a photo-sensitive agent, which compounds give high resolution, high contrast and thick-film formability when compounded in a positive photo-sensitive resin composition. The present invention furthermore provides a new type positive photo-sensitive resin composition obtained by reacting a polybenzoxazole precursor with a diazoquinone compound as a photo-sensitive agent. This photo-sensitive resin composition has excellent alkali resistance when unexposed to a light and accordingly can give a high residual film ratio.

Abstract: A power control circuit which provides a means of limiting the active power required by a CMOS EPROM device. A "zero" power direct current (DC) quiescent mode of operation is achieved which enables the EPROM to remain in an active state with outputs active and inputs ready to accept data without power drain to the power supply or battery. On detection of an address transition or chip enable transition, a "power up" sequence occurs. The sense amplifiers, bias circuits and redundancy circuits are preconditioned to accept data. The sense amplifiers and data lines are equalized (precharged) and the bias circuits are powered up. Next, the sense amplifiers are allowed to accept new data from the EPROM core cell. Finally, the data is latched into an output buffer and all circuits are powered down to the "zero" DC power state. The next transition in address location will cause the process to repeat. The present invention enables an EPROM to remain in the active mode with lower overall power drain on a battery.

Abstract: Disclosed are an audio signal recording apparatus and method for recording in a plurality of tracks (T) a video signal and an audio signal of say four channels corresponding to the video signal, the tracks constituting one segment. The audio signal is recorded in a recording area (PA) separate from that (VA) for the video signal on a tape. The audio signal of the four channels is divided into groups each associated with a plurality of channels. Each group of audio data is recorded in one of audio signal recording blocks (PA12, PA34) obtained by dividing the audio signal recording area (PA) in the longitudinal direction of the tracks (T). The groups of audio data are each given a priority depending on the importance of the data, and data of high priorities are recorded in blocks (PA12) that are farther away from the track ends where the contact between tape (4) and head (1, 2) may be unstable.

Abstract: A field emission source is used in conjunction with a three element asymmetric lens system to provide an electron gun having greater magnitude beam currents focused on a smaller spot size than has been previously possible for intermediate energy beams. The three element asymmetric lens system has a lower spherical aberration than prior art electrostatic guns and a very low chromatic aberration coefficient, enabling precise focusing of beams with large currents and energy spreads. The electron gun produces high current densities in beams focused on small spot areas, despite the relatively large acceptance angle and energy spread of the source beams.

Abstract: Encoding and decoding devices which are capable of increasing the encoding and decoding speed. In arithmetic encoding (prediction encoding), there is a possibility of encoding with high efficiency which is very close to the entropy of the information source, but the encoding and decoding time is generally longer than that in another encoding systems such as an MMR encoding system. For example, in a standard facsimile equipment, about 1.3 sec is required for encoding the picture information in an A4-size copy. In prediction encoding, a memory for storing the past reference symbols and the predicted values therefor is necessary for prediction. Since the memory capacity is generally large, a large-capacity RAM is used. The encoding time is therefore greatly dependent on the access speed of the RAM. In the present invention, a high-speed register for storing the predicted value for a special symbol pattern is provided separately from the RAM so that the predicted value of the special symbol pattern is read from this register, thereby enabling high-speed encoding.

Abstract: Control circuitry for electrical starters, contactors having a starting winding and a serially coupled holding winding.

In one embodiment, the unshorting of the holding winding is delayed a predetermined number of cycles after the separable main contacts have closed to avoid the necessity of relatively accurate mechanical sensing of the position of the separable main contacts: In alternate embodiments, control circuits are provided which allow the limit switch normally used for sensing the position of the separable main contacts, to be eliminated altogether.

Abstract: The velocity, and consequently the flight-time, of ink drops (17) in a continuous jet marking system is controlled despite variations in the composition of the system ink (16) due to variations in operational temperature and variations in ink viscosity caused by the return of unused ink drops by a collector (22). A three-way valve (14) is operated by a controller (28) so that the nozzle (12) can be supplied either with system ink (16) or fresh ink (36). A drop velocity detector (24) determines the velocity of the ink drops (17) and a pressure sensor (26) determines the associated ink pressure. The system ink (16) and the fresh ink (36) are subjected to the same operational environment and the controller (28) periodically compares the pressure required to maintain a predetermined drop velocity with the fresh ink (36) with the pressure required to produce the same ink drop velocity with the system ink (16). Because both ink supplies (16 and 36) are subject to the same operational environment, the difference between these pressures indicates a change in the viscosity of the system ink. The controller (28) assesses this pressure difference and operates a pump (32) to add solvent from a reservoir (34) into the system ink (16) to restore its viscosity to a desired value.
