IPC: H02P6/28
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To completely eliminate the necessity of a gain adjustment by determining a switching command signal to turn each of main circuit switching power element on or off by a renewal timing and a timing when the current comparison result changes from a small value to a large one. SOLUTION: A current command signal iT is compared with a first, a second, and a third line current detection result iFU, iFV, iFW by a current comparing means 11. A current level R1, being H level when one of these line current detection results iFU, iFV, iFW is larger than the current command signal iT and L level in the other cases, is output to a switching command signal generating means 12. Then, the switching command signal generating means 12 determines whether each main circuit switching power element should be turned on or off by a time of the rise of a renewal timing signal T1 from a timing generating means 10 and a timing when the current comparison result changes its level.

Title: Power supply circuit of amplifier
Inventor: SUEYOSHI SUSUMU
IPC: H03F1/02
Filed: 1982-02-02
Abstract: PURPOSE:To prevent the generation of distortion due to a delay of operation of a power supply circuit and at the same time to improve the power converting efficiency, by using the 1st and 2nd power supplies, an amplifying transistor (TR), a driving TR and a power supply TR. CONSTITUTION:Now the circuit output vO is small and set at¦vO+ or -VF¦<VL, diodes D3 and D'3 are turned off with diodes D1 and D'1 turned on respectively. As a result, the feed is carried out to the collectors of amplifying output TRs Q2 and Q'2 by means of the 1st power supply + or -VL. A follower output¦vO+ or -VF¦ of the 2nd power supply produced by power supply output TRs Q3 and Q'3 is supplied to the collectors of driving TRs Q1 and Q'1. The TRs Q1 and Q'1 and TRs Q3 and Q'3 function as cascade circuits. As a result, VCE of the TRs Q1 and Q'1 is kept at constant¦VF¦. At the same time, the TRs Q3 and Q'3 are always active as long as the TRs Q1 and Q'1 have A-class operations. The TRs Q3 and Q'3 function as cascade TRs not only to the TRs Q1 and Q'1 but to the TRs Q2 and Q'2 if the output vo is increased and¦vO+VF¦>=VL is satisfied. Thus the VCE can be kept at a constant level for TRs Q1 and Q'1 as well as TRs Q2 and Q'2.

IPC: H04N7/18
Filed: 1993-01-04
Abstract: PURPOSE:To hold a thermal image of the highest or the lowest temperature by comparing a stored thermal image signal with an input thermal image signal in unit of pixels and controlling them. CONSTITUTION:Infrared rays 2 emitted from an object 1 are written via a comparator 16 as a thermal image signal by an infrared ray detector 9 into a frame memory 15 as a stored thermal image signal. Then the signal is compared in the comparator 16 with input thermal image signals which are input to the comparator 16 one after another. When the thermal image signal is of higher or lower temperature than the stored image thermal signal stored in the frame memory 15, a control signal is output from the comparator 16, which is input into a write control circuit 17 to control write of the input thermal image signal into the frame memory. Thus the thermal image signal of the highest or the lowest temperature is always written in the frame memory 15.

Abstract: PURPOSE: To purify a mono-(long-chain alkyl) aliphatic amine derivative, and to reduce the odor thereof, by the catalytic hydrogenation under specific conditions.  
     CONSTITUTION: A mono-(long-chain alkyl) aliphatic amine (e.g. dodecyl dimethylamine, dodecylamine, etc.) is purified by contacting with hydrogen in the presence of 0.05W2.0wt% of a Raney catalyst, under a hydrogen pressure of 1W50kg/cm 2  gauge, at 20W100°C. The strong odor, which is a weak point of mono-(long-chain alkyl) aliphatic amine and is especially remarkable in the one obtained from low- molecular ethylene polymer (e.g. α-olefin, Ziegler alcohol, etc.), can be improved by the catalytic hydrogenation in the presence of a Raney catalyst.  
     USE: The alkyl betaine derivative and the quaternary ammonium derivative of the amine are useful as a component of textile finishing agent, antistatic agent, detergent, and cosmetics.
