Title: Hydraulic actuator
Inventor: MIZUNO JUNJI
IPC: F15B15/08
Filed: 1985-08-07
Abstract: PURPOSE:To make a hydraulic actuator unit small in size by installing a hydraulic pump along an oil pass connecting a primary hydraulic chamber and a secondary hydraulic chamber of a double acting cylinder. CONSTITUTION:A hydraulic pump 24 is installed along an oil pass connecting a primary hydraulic chamber 12 and a secondary hydraulic chamber 13 of a double acting cylinder 11, and this hydraulic pump 24 pumps oil from the primary hydraulic chamber 12 to the secondary hydraulic chamber 13 to drive a piston 14. This constitution disuses a reserve tank of large volume as conventionally used, and instead only needs an oil cup 26 of relatively small volume. Therefore, miniaturizing of a hydraulic actuator unit is possible.

Title: Receiving probe for nmr
Inventor: YODA KIYOSHI
IPC: A61B10/00
Filed: 1987-07-14
Abstract: PURPOSE:To obtain a receiving probe with an easier adjustment and a higher sensitivity, by adjusting first and second reverse bias voltages to perform a resonance and an impedance matching at a specified frequency. CONSTITUTION:Impedance allowed for a receiving coil 1 from an input/output terminal 4 at a specified frequency can be adjusted to, for example, 50OMEGA by applying a specified DC voltage to first and second reverse bias application terminal 13 and 23, hence maximizing the sensitivity of a coil 1. Here, it is necessary to connect a transmission cable which is to be connected to the coil 1 as balanced impedance or to a terminal 4 as unbalanced impedance. To achieve this, a DC blocking capacitor 30d and a high frequency ground point O are connected to the terminal 4 with the midpoint of solid capacitors 14a and 14b as high frequency ground point O. Diodes 5a and 5b for suppressing resonance current can suppress resonance current as caused by interlinkage of a transmitting magnetic field with the coil 1 generated from a transmitting coil.

Title: Communication terminal equipment
Inventor: TADOKORO YOSHIHISA
IPC: H04N1/32
Filed: 1989-07-07
Abstract: PURPOSE:To instruct the processing of a received original by one operation by transmitting a voice message relating to a transmitting original at the time of transmitting the original. CONSTITUTION:At the time of receiving a signal indicating the start of voice message transmission from a transmission side equipment, the receiving side outputs the sent voice message from a voice I/O device control part 18 to a speaker to be a voice I/O device 19 through a communication control part 16. On the transmission side, a communication control part 16 transmits image data compressed by a coding/decoding part 15, and on the receiving side, the received compressed image data are decoded and printed out to a printer 3. Since the voice message can be transmitted together with an original at the time of transmitting the original, the received original can be processed by the method instructed by the voice message.

IPC: H04H40/36
Filed: 1980-12-10
Abstract: PURPOSE:To prevent the degradation of the degree of stereo separation even for lowering of the carrier level, by cutting off the transmission line of a subchannel signal to perform monaural reproducing when it is detected that the carrier level of the receiving signal becomes lower than a prescribed level.

Title: Portable telephone with pocket beeper
Inventor: TOYONAGA TAKEMORI
IPC: H04W88/00
Filed: 1994-06-22
Abstract: PURPOSE:To save charging (power) of the portable telephone by integrating a pocket beeper with the telephone and turning on the power source of the telephone with energy to reach the signal of the pocket beeper to a party. CONSTITUTION:The portable telephone pocket beeper is also composed of ten digits and calls the opposite party. These two communication numbers are made equal, the pocket beeper is integrated with the telephone, and the power source of the telephone is turned on by the energy for dispatching the signal of the pocket beeper to the party. Thus, when the same 10 digits are pushed from the telephone on this side to both the stations and a repeat button is depressed, the pocket beeper is first dispatched and after the power source of the telephone is turned on, the dial of repetition is dispatched again. Therefore, when the bell of the telephone rings, it is enough only to pickup a receiver and to speak. Thus, since the power source of the portable telephone is turned on only at speaking time, power is consumed but since the battery of one pocket beeper is normally kept for two or three months, the power of the portable telephone can be saved.
