Title: Integrated communication apparatus of small-zone-type wireless telephone with paging system
Inventor: BUARUTAA GISURAA
IPC: H04B7/26
Filed: 1992-04-17
Abstract: PURPOSE: To provide a mobile radio telephone system which can by used for a small-zone mobile telephone system and can save the powder consumption of a battery. CONSTITUTION: The conventional mobile telephone set largely consumes electric power for monitoring calls to its own set. A call device used for a paging system, on the other hand, bas an inferior function as compared with a telephone set has, but the power consumption of the paging system when the system monitors calls to its own set is considerably smaller than that of a mobile telephone set. Therefore, a mobile telephone set 30 is combined with a call device 21 and the device 21 is made to monitor calls to its own device while the telephone set 30 is set to a rest mode in which the power consumption of the telephone set 30 becomes smaller and, when the device 21 is called, a power supply making command is issued to the telephone set 30 so that the set 30 may fulfill its function as a telephone set. Therefore, the power consumption of this integral communication equipment is reduced as a natural consequence.

Title: Rotary preset channel selection device
Inventor: OOSHIMA TAKEKI
IPC: H03J5/06
Filed: 1978-08-12
Abstract: PURPOSE:To realize the rotary preset channel selection which features a small amount of force necessary for the rotary operation to perform the channel selection along with the excellent controllability by holding the memory device via the 2nd cam face at the maximum shift position caused by the 1st cam face until turning by the fixed angle. CONSTITUTION:The value prescribed from outside can be adjusted for memory device 29 which can turn freely, and cam 36 possessing cam faces 37 and 38 has turning according to the turn of device 29. Movable piece 19 touches cam 36 elastically and also shifts the tuning element against the energizing force. Piece 19 is shifted from cam face 37 and then moved up to the maximum shift position to be held 38 by face 37 until device 29 has been turned to the fixed angle. Thus the turning of device 29 can be made best use to the temporary shift of the tuning element, thus reducing the force necessary for the rotary operation to perform the channel selection. As a result, the rotary preset channel selection is possible with excellent controllability.

Title: Ultrashort light pulse supply device
Inventor: MOGI KAZUO
IPC: G02B27/00
Filed: 1990-04-13
Abstract: PURPOSE:To prevent waveform distortion due to dispersion on an optical transmission line regardless of transmission wavelength by providing a dispersion correction optical system successively on the optical transmission line and giving dispersion characteristics which are reverse of dispersion characteristics that the optical transmission line has. CONSTITUTION:The optical transmission line 1 is provided successively with the dispersion correction optical system 5 that have the dispersion characteristics the reverse of the dispersion characteristics that the optical transmission has. In this case, pulses which are dispersed by the dispersion correction optical system 5 are affected by the dispersion on the transmission line while propagated in the optical transmission line 1, but the deformation of the affected pulse waveform has effect reverse of that given to the dispersion correction optical system 5 in advance, so both effect of the dispersion cancel each other when the light is projected from the optical transmission line. The pulse waveform is therefore restored to the state at the time of incidence on the dispersion correction optical system 5. Consequently, the pulse supply device which has no waveform dispersion regardless of the wavelength of ultrashort pulses even when the ultrashort pulses are supplied is obtained.

Filed: 1988-04-21
Abstract: PURPOSE:To improve reliability by reducing in thickness the rear face of a semiconductor integrated circuit to a predetermined thickness by a mechanical polishing method, then removing a polished layer, and mounting a semiconductor integrated circuit after removing. CONSTITUTION:After a semiconductor integrated circuit (IC) 4 in which a rear face polished layer is removed adheres to a glass epoxy board 1 having electrodes 2 by curing die bonding resin 3, the pads of the IC 4 are connected to leads 5 by wirings 6. Then, the surface of the IC 4 and the part of the board 1 are covered with sealing resin 7, thereby completing an IC module. Accordingly, since the IC 4 has no microcrack at the polished face for reducing in thickness, even if it is mounted on a commodity in which an external force is applied to the IC module with thin type like an IC card, the IC contained therein is scarcely cracked. Thus, reliability can be improved.

Title: Variable inductance device and magnetic field intensity measuring device
Inventor: TAGAWA KOSEI
IPC: H01F21/02
Filed: 1988-04-21
Abstract: PURPOSE:To simplify and accelerate an operation by disposing a superconductor in a magnetic field region generated by a current flowing to a coil, varying an external magnetic field by external magnetic field varying means to alter the magnetic properties of a superconductor, and varying the inductance of the coil. CONSTITUTION:When an external magnetic field intensity is varied by external magnetic field varying means, the magnetic properties of a superconductor 1 is varied in response to the variation in the intensity. Since the superconductor 1 is disposed in a magnetic field region generated by a current flowing to a coil 2, the inductance of the coil 2 is altered in response to the variation in the magnetic properties of the superconductor 1. Accordingly, the variation in the inductance of the coil 2 can be varied by altering the intensity. Further, when the varying means is composed of a coil connected to a power source, the intensity can be altered in response to a signal from the power source, and the inductance of the coil can be varied on the basis of the signal from the power source. Thus, the operation can be simplified and accelerated.
