Title: Output circuit
Inventor: MATSUMOTO TADASHI
IPC: H03K17/687
Filed: 1986-02-19
Abstract: PURPOSE:To prevent effectively the malfunction or the like of a circuit and to reduce the power consumption due to a through current by preventing the variance or the like of the earth level due to the through current. CONSTITUTION:The circuit is so controlled that one of two pairs of PMOS transistors TRs T1 and T3 and NMOS TR T2 and T4 are operated when an output level 0 rises from a time t1 to a time t2 or falls from a time tau1 to a time tau2. Consequently, the supplied current is controlled and the output level 0 has a smooth rise or fall characteristic. The other pair of PMOS or NMOS TRs are turned off then. Thus, the evil of flow of the through current is prevented.

Title: Optical recording and reproducing device
Inventor: NIMATA AKIO
IPC: H01S5/00
Filed: 1985-02-20
Abstract: PURPOSE:To obtain a simple driving circuit for semiconductor laser which can cope with both recording and reproducing actions of information, by using a circuit which bypasses the detection current corresponding to a superposed recording current from the total detection current of a laser light intensity detecting part when a recording current is supplied. CONSTITUTION:A compensating circuit 4 controls a drive current I2 so as to keep a fixed level of the optical output Pr. The total detection current I4 of a photodiode 2 is equals to I6+I7, where the total optical output is refeered to as Pw when a record ing current I3 is flowed with superposition to a semiconductor laser LD1 and the superposed detection current of a photodiode 2 corresponding to the current I3 is I7 respectively. Then the current I4 is converted into voltage through the resistance of a laser light intensity detecting part 3. Then only the component of the current I7 is extra and the current I2 changes. here a current I5 flowing to a transistor TR11 is controlled so that the current I7 is supplied to a TR13 of a current extracting circuit 10. The current I7 is proportional to the current I3 and therefore the current I5 can be set easily at I3/k by means of a fixed attenuator 9 as long as a coefficient is defined as 1/k. Thus the constant (k) of the attenuator 9 is set so that I7=I5=I3/k is satisfied.

Abstract: PURPOSE: To achieve partial inactivation of floor heating panels connected side by side to each other, each panel having work fluid sealed therein and formed with a vaporizing section at one end and a condensing section at the other end, by attaching a freely opened valve to the condensing section of each panel.  
     CONSTITUTION: A valve 6 is attached to a heat panel H at one end portion of a condensing section 4, and a plurality of such heat panels H are connected to each other by a header pipe 2. In inactivating part of heat panels H, air in the heat panel H to be inactivated is drawn out by opening the valve 6 of the panel H while measuring the temperature on the surface of the panel, H until a required area is rendered inactive.

Title: Impulse generating circuit
Inventor: KATSUYAMA YOSHIRO
IPC: G01R31/28
Filed: 1990-02-14
Abstract: PURPOSE:To generate an impulse with a momentarily large power by causing a timewise deviation in a change timing of a drive pulse output of 1st and 2nd driver circuits and supplying a surge current to a series circuit comprising of a capacitor and a radio wave radiation load. CONSTITUTION:When a pulse is inputted from a pulse generator 10, an output signal having a delay time D is outputted respectively from a delay element 1 and driver elements 2, 3. When the pulse is inputted at a time t1, an output level of the element 3 changes from L to H at a time t2 after the lapse of the time D. On the other hand, since an output change of the element 2 is delayed further by the delay time D in the element 1, the output level changes from H to L at a time t3 after the lapse of a time 2D. An instantaneous surge of discharge current flows to the capacitor 5 at times t2, t3. On the other hand, the instantaneous surge of discharge current flows at a time t5 when both the outputs of the elements 2, 3 are at L and at a time t6 when the element 2 goes to H and the said current flows also to an antenna load 4 as a load current and an electromagnetic wave including lots of harmonic waves is radiated from the antenna.

Title: Camera capable of correcting blur
Inventor: ITO JUNICHI
IPC: G03B17/00
Filed: 1994-03-03
Abstract: PURPOSE:To inhibit the supply of power to a sensor from being frequently stopped and to eliminate a failure not to take a vibration proof action caused by the unstabilization of the sensor by restricting a transfer from a normal mode to a standby mode when a vibration proof mode is selected. CONSTITUTION:A main microcomputer (MmuCOM) l decides the state of a MODE SW, to decide whether a submicrocomputer (SmuC0M) 83 is in a state where vibrationproofing is possible or not. The submicrocomputer (SmuCOM) 83 sets the signal of an output port p-EN1 to a low level from a high level when the outputs of camera-shake detecting circuits 87 and 88 become a usable state. The main microcomputer (MmuCOM) l sets a vibrationproofing permitting flag '1', to initialize a timer counter. Thus, when the MODE SW is turned on, the timer counter is always initialized and an overflow never occurs. In other words, the main microcomputer (MmuCOM) 1 is never transferred to the standby mode.
