Title: Color television camera
Inventor: MURATA NORIO
IPC: H04N9/04
Filed: 1985-02-14
Abstract: PURPOSE:To perform sufficiently while balance and shading correction by inserting a reference pulse to a blanking period of a video signal before a preamplifier, detecting the pulse after the preamplifier to obtain a gain of the preamplifier and changing the shading correction quantity based on the result. CONSTITUTION:The gain of analog/digital gain converters 2b, 70 is set to a preset value under the standard lighting condition, shading information stored in a memory 10 is read and the shading quantity included in a video signal (c) is eliminated by a subtractor 30. When the lighting condition changes, a white object is picked up for the image to take white balance and an AWB control circuit 80 controls the gain of the analog gain converter 2b to bring a video signal (v) to a prescribed value. In this case, an SG control circuit 60 measures a level of a reference pulse inserted into the video signal (c) to control the gain of the digital gain converter 70.

Title: Manufacture of high purity al alloy foil for electrolytic capacitor
Inventor: TOMA KEN
IPC: C22F1/04
Filed: 1988-02-05
Abstract: PURPOSE:To increase the occupying rate in the (100) face of the title foil and to improve the electrostatic capacity of the foil subjected to etching at the time of rolling a high purity Al alloy contg. specific amounts of In and Na and thereafter subjecting it to recrystallization annealing at a prescribed temp. by specifying the heating conditions. CONSTITUTION:The ingot of the high purity Al alloy formed by adding and incorporating 0.1-90ppm Cu and/or Na to high purity Al having >=99.9% purity is subjected to hot rolling and cold rolling under ordinary conditions and is thereafter finally subjected to recrystallization annealing to manufacture the high purity Al alloy foil. At the time of the manufacture, the alloy is heated at <=1.5 deg.C/min heating speed at least in the temp. range of 100-300 deg.C at the time of heating in the above recrystallization annealing. By this method, the occupying rate in the (100) crystal face of the foil can be increased to >=90%. The electrostatic capacity of the foil after etching and forming of an oxidization film thereon is therefore made high.

Title: Method for generating pilot arc or plasma torch
Inventor: HOSHINO TADASHI
IPC: B23K9/00
Filed: 1987-02-06
Abstract: PURPOSE:To elongate the length of the plasma stream by a pilot arc and to improve the operability by interposing a high frequency current on the power source current for a pilot arc temporarily and increasing the gas amt. feeding to the pilot arc for specific time as well. CONSTITUTION:With the turn ON of a power source switch SW1 a solenoid SOL1 is energized to open a solenoid valve MV1. The pilot gas in the flow amt. set by an adjustment valve AV1 is flowed. A switch SW2 is for generating a pilot arc and when this is closed a high frequency power source is actuated to generate the pilot arc between the electrode of a torch and a nozzle. A solenoid SOL2 is energized at this time to open a solenoid valve MV2, so the gas in the flow amt. set by the adjustment valve AV2 is fed excessively. The working time of the high frequency power source stops at the time when a contact is opened by the relay which works with the flow of a current by igniting the pilot arc. The solenoid SOL2 and high frequency power source are cut off by opening the contact at the time when a set time comes.

Title: Dimming device for fluorescent lamp
Inventor: FURUTA JUTARO
IPC: H05B41/392
Filed: 1988-02-09
Abstract: PURPOSE:To reduce power consumption and weight by employing a switching means which can be controlled with a pulse signal and by controlling the light emission of a fluorescent lamp by controlling the pulse duration. CONSTITUTION:When an NPN type transistor 6c is on, the condition becomes as a condenser 6a being inserted in parallel, a current flows through the filament of a fluorescent lamp 4, and the voltage applied between opposing electrodes of the fluorescent lamp becomes smaller than a discharge continuation voltage. As a result, the fluorescent lamp 4 becomes non-discharge condition. When the NPN type transistor 6c is off, the potential of the condenser 6a is kept approximately constant by a diode 6b, the voltage between the opposing electrodes becomes higher than a discharge start voltage, and the fluorescent lamp becomes discharge condition. Controlling the on and off conditions of the NPN type transistor by a brightness control signal generating device 7, the brightness of the fluorescent lamp can be continuously controlled. This arrangement makes it possible to reduce the weight and power consumption of a switching means.
