Patent JP-S5911593-A (JP)
Title: Decoder circuit
Inventor: ICHIYAMA TOSHIO
IPC: G11C29/00
Filed: 1982-07-09
Abstract: PURPOSE:To attain a decoder circuit suitable for high circuit integration, by connecting a pair of input signals having opposite polarity at an effective period of the signal in common with a gate of a transistor (TR) with two wirings possible for being cut with a laser beam, for using a TR only, which had bead required for two TRs to a pair of input signals in conventional method. CONSTITUTION:Before the logic of a decoder is constituted by a laser beam, a gate potential of a TRQ31 is set to an H level through a wiring T30, and a TRQ31 turns on. Further, since the signal is kept to an L level, a TRQ32 turns off. On the other hand, when the logic of the decoder is constituted with the laser beam, wirings T20, T30 are cut off. Thus, the signal I is set to an H level and a gate signal of the TRQ31 is set to an L level, and a signal II is set to an L level. Thus, the TRQ30 is turned off, input signals Ao, Ao',-Am, Am' are transmitted to inputs Ao1, Ao1'-Am1, Am1', and the decoder circuit is activated by cutting off one of wirings T12, T13; T14, T15; and T16, T17, and the state of logic of an output W is determined corresponding to the input signals Ao, Ao',-Am, Am'.

Title: Phonocardiograph
Inventor: OGURA TOSHIHIKO
IPC: A61B7/04
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a phonocardiograph which can be stably fixed at a subject' s chest without using an examiner's hand. SOLUTION: When a pressing part 14 of this phonocardiograph 10 placed on a subject's chest is pressed, a diaphragm 22 is pressed and deformed, and a variable volume room 32 between a housing main body 20 and the diaphragm 22 is tentatively made smaller. When the deformed diaphragm 22 is released and the variable volume room 32 is enlarged, the pressure inside the variable volume room 32 and a circular groove 40 connected to it by means of a through hole 38 becomes negative, so that a housing 18 is stuck and fixed to the skin 16 of the subject.  As the phonocardiograph 10 can be stably fixed to the subject' s chest without using the examiner's hand in this way, noises generated when the device is continuously pressed by hand or noises generated because by insufficient fixture of the device adhered with adhesive tapes or both-sided adhesive tapes can be prevented from mixing into cardiac sound signals, and a precise phonocardiogram can be obtained.

Title: Communication equipment
Inventor: TAGAMI KAZUHIKO
IPC: H04M1/274
Filed: 1994-05-10
Abstract: PURPOSE:To improve function for radialing by an automatic call originating means for reading and automatically dialing a telephone number in a dial number storage means with a prescribed key. CONSTITUTION:When off hook is detected, next, it is judged whether a reserve key 1a is depressed or not and when the reserve key 1a is not depressed but a dialing is performed, the dialed telephone number is identified. Then, the identified telephone number is stored in the prescribed area of a storage part 4. On the other hand, when it is judged that the reserve key 1a is depressed, the telephone number already stored in the reserved number storage area of the storage part 4 is read out, and the call is automatically originated to that telephone number by the automatic dial operation. Thus, the telephone number dialed in the off-hook state is stored by the prescribed key operation and afterwards, the call is automatically originated to the stored telephone number by the prescribed key operation without any dial operation.

Title: Audio regenerating system and audio regenerating method of video cassette recorder
Inventor: KIN SAITAI
IPC: G11B5/008
Filed: 1992-05-13
Abstract: PURPOSE: To prevent audio noise by a phase difference by detecting the phase difference between audio signals generated when an audio head is switched and correcting an error by the detected phase difference. CONSTITUTION: A correction signal generation part 43 detects a time difference Δt corresponding to the phase difference of the audio signals S1 and S2 detected in the audio head 21, then outputs correction signals to RAMs 39, 41 and delays the output of the RAMs 39, 41 for the time difference Δt when the RAMs 39, 41 output the audio signals S1 reproduced in the audio head 21. Thus, since one continuous audio signal for which the phase difference is corrected is attained, the noise by the phase difference is prevented.

Abstract: PURPOSE:To control boiler load so as to develop a good overall efficiency and provide a method of boiler load control that is energy saving and safe by carrying out load control so as to make E/eta minimum as the steam pressure is kept within a certain range. CONSTITUTION:When only a boiler I is solely operated, the steam pressure P in the header 4 is detected by a pressure sensor 5 and its signal is sent to a controller 6. As long as the steam pressure P is within the range of  Pp signals such as the evaporation quantity E and/or feed water quantity W from a steam flow rate detector 9 and/or a feed water flow rate detector so the fuel quantity B from a fuel flow rate detector 8 and the feed water temperature tw from a feed water temperature detector 11 and the air temperature ta from an air temperature sensor 12 and so on are sent to the controller 6 every moment. In the controller 6 the boiler efficiency is calculated, and next E/eta of the boiler is calculated and stored in the memory. And, the value E/eta is compared with the preceding one and if the present value is lower, a combustion- air valve 7 is controlled so as to bring E/eta further lower, and if the present value is higher, the valve 7 is controlled so as to bring E/eta in the direction of returning. With this arrangement the reliability of the device is raised and the boiler is operated always safely.
