Inventor: MIKAMIMURA YASUKI
IPC: H03F17/00
Filed: 1988-09-06
Abstract: PURPOSE:To make an output characteristic flat by providing the serial circuit of a resistance and a capacitor between the output of a voltage follower and the cathode of a photodetector in a light-receiving amplifier with bootstrap, where the capacity of the light-receiving element is equivalently reduced. CONSTITUTION:In the conventional light-receiving amplifier with bootstrap, the series circuit of the capacitor CB and the resistance RD is connected. Thus, a part of the equivalent capacity reducing effect of the photo diode PD is sacrificed by the bootstrap, but waviness on the high band-side of the output characteristic is controlled and the output characteristic goes flat.

Title: Television camera
Inventor: FUJII MUNEAKI
IPC: H04N5/376
Filed: 1988-09-06
Abstract: PURPOSE:To reduce number of signals sent through a control line by superimposing a vertical synchronizing signal component and a horizontal synchronizing signal component of a television signal onto a video signal on a transmission line sent from an image pickup section to a control section. CONSTITUTION:A signal oscillated by an oscillation circuit 50 of an image pickup section 1 is sent to a drive circuit 20, from which a vertical synchronizing signal, a horizontal synchronizing signal, a drive signal of a solid-state image pickup element and a sample signal are generated. A mixing circuit 30 mixes a sampled signal and the vertical synchronizing signal, the horizontal synchronizing signal from the drive circuit 20 and outputs the result to a control line 2. Then a video synchronizing separator circuit 60 separates the TV signal into a video signal and a synchronizing signal, the phase of the horizontal synchronizing signal of the synchronizing signal is compared with the phase of the horizontal synchronizing signal of a synchronizing signal circuit 80 of a control section 3 and the result is outputted to an oscillation circuit 90 as an oscillation frequency control voltage. The vertical synchronizing signal is used as a vertical reset signal of the circuit 80. Thus, the control section 3 and the pickup section 1 are synchronized completely. Thus, number of signals through the control line 2 is decreased and the cost is reduced.

Abstract: PROBLEM TO BE SOLVED: To get good combustion state even if the positional relation between an opening and a fuel supply pipe is various, by equipping a liquid fuel combustor with a burner head for combusting the mixture of liquid fuel vaporized with a vaporizing cylinder and air for combustion, and shaping an opening like an oblong. SOLUTION: Fuel is supplied from a fuel supply pipe 3 to a vaporizing cylinder 1, and air for combustion is supplied from the fuel pipe 3 of an opening. The liquid fuel is made into fine particles by air, and vaporizes, colliding against the inwall of the vaporizing cylinder 1 kept at high temperature by a heater 2, and passes a split board 5 and a straightening plate 6, and forms a flame above the periphery of a burner head 7. The shape of the opening 1a of the vaporizing cylinder 1 is an oblong which have sides parallel to each other, so the flow velocity of the air supplied from the opening becomes equal in the vicinity of the center. Hereby, the atomization property of the fuel improves, and a stable flame can be formed above the periphery of the burner head.

Title: Cooler of motor in refrigerator
Inventor: KOBAYASHI SATORU
IPC: H02K9/20
Filed: 1983-11-30
Abstract: PURPOSE:To reduce the frictional loss when cooling a motor with coolant by not filling the coolant in a space for containing a rotor of the motor and maintaining the space at a low pressure. CONSTITUTION:Coolant is evaporated by heat generated from a stator 7 in a sealed space 10A to become coolant vapor. The stator 7 and the periphery are cooled by the evaporating latent heat when the coolant is evaporated. The coolant vapor in the space 10A is fed from an outlet 12 through an exhaust passage 14 to an evaporator 5 or the suction side of a compressor 2. Thus, since the coolant is introduced only into the periphery of the stator but not introduced to a housing 6 which contains a rotor 9, the pressure in the housing 6 is maintained lower than the space 10A, and the frictional loss when the rotor 9 is rotated can be reduced in the amount corresponding to the lower pressure.
