Title: Manufacture of corrosion and fatigue resistant copper and copper alloy pipes
Inventor: TODA YOSHIHISA
IPC: B23K13/00
Filed: 1984-01-13
Abstract: PURPOSE:To obtain a welded Cu or Cu alloy pipe having superior fatigue resistance and corrosion resistance by work-hardening of Cu or Cu alloy bar, forming it into an arbitrary shape, and carrying out continuous welding by induction welding or resistance welding.

Filed: 1991-01-17
Abstract: PURPOSE: To improve low noise margin and to always obtain a voltage boosted to a fixed level when an external voltage is fluctuated by providing a pair of pull-up, pull-down NMOSs and a bootstrap circuit. CONSTITUTION: A pair of pull-up and pull-down NMOS transistors NM1, NM2 connected in series are provided between a first supply voltage line SL1 and a ground line SL2.

Title: Stroboscopic photographing alarming device
Inventor: SEGAWA HISASHI
IPC: G03B7/16
Filed: 1986-01-13
Abstract: PURPOSE:To previously prevent the generation of a photographing miss by detecting a step difference between exposure data based on the luminance of an object and an aperture data based on distance information and generating an alarm when the step differences is too large to photograph. CONSTITUTION:When a main object is positioned on the far distance position and the luminance of a background is high, the maximum aperture Fm of a lens based on exposure data is reduced, and the lens aperture data Fs is fixed by a guide number, so that the step differences Fs-Fm is increased. An alarm circuit 13b compares the step differences Fs-Fm of the lens aperture calculated by a step difference arithmetic circuit 13a with a reference level. When the step differences Fs-Fm exceeds the reference level, the circuit 13b outputs a signal to drive a display lamp 14 and inform the impossibility of photographing. Consequently, a photographer can reduce the step difference between the exposure data and aperture data as small as possible and take a picture based on proper exposure by shortening a distance up to the object or changing the composition of the picture.

Filed: 1987-01-12
Abstract: PURPOSE:To make effective use of an optical disk by forming tracking regions of a low reflectivity to a recording member, which is decreased in the reflectivity by quick cooling after heating and is increased in the reflectivity by slow cooling after heating, to a spiral shape centering at the center of the rotation thereof except recording and reproducing regions of a high reflectivity. CONSTITUTION:A thin recording film 22 consisting of a resin which is constituted of the two components; vinylidene fluoride copolymer and methacrylate copolymer and is formed as a thin film. Transmittance which is initially about 80% is degraded to about 10% with about 175 deg.C as threshold when the film 22 is heated. On the other hand, about 80% transmittance is restored by slow cooling and about 10% transmittance is maintained by quick cooling when the film 22 heated once in excess of the threshold is cooled. The tracking regions 24 of the optical disk 2 are the parts where the transmittance of the thin film 22 is low and the recording and reproducing regions 25 are the part where the transmittance of the film 22 is high.

Abstract: PURPOSE:To keep a content liquid at a high temperature without boiling it by setting the heating conditions of the content liquid by judging its temperature declining characteristics from the output of a room temperature sensor and that of a sensor for detecting the amount of the content liquid, and reheating the content liquid. CONSTITUTION:When boil treatment is completed after the power source of an electric hot-water storage container is turned on to energize a heater, the step is shifted to a step 4 of heat reserving treatment. When a heat reserving mode is detected in a step 11, the fetching of the room temperature data is started by a step 12. Also, the fetching of the liquid amount data is started by a step 13. By a step 14, the temperature declining characteristics are judged from the room temperature data and the liquid amount data, and the wattage for energizing a heater is judged. Then, heater is reheated so that the wattage judged by a step 15 is added. Thereby, the content liquid does not boil, and it is kept at the desired high temperature.

Filed: 1983-01-17
Abstract: PURPOSE:To realize the isolation between transmission and reception with a simple constitution by providing a power-down function to an amplifier which amplifies the output of a synthesizer up to a drive level or a reception local level of a transmission power amplifier. CONSTITUTION:An amplifier 12 varies the power supply voltage supplied to an amplifier 14 between the transmission and reception modes via a transistor TR1, a switching circuit consisting of resistances R2 and R3 and a resistance R1. Thus the output of the amplifier is varied. When a press switch 15 is turned on, a current flows through resistances R2 and R3 to turn on the TR1. Then the power supply voltage is applied to the amplifier 14, and the output of the amplifier 12 delivers the drive level of a transmission power amplifier 4. While the TR1 is turned off when the switch 15 is off and in a reception state. Then the voltage lower than the power supply voltage by an amount equal to the voltage drop of the R1 is supplied to the amplifier 14. Therefore the output level of the amplifier 12 is reduced compared with the level set in a transmission mode.
