Title: Block decomposition circuit
Inventor: FUJIMORI YASUHIRO
IPC: H04N19/98
Filed: 1988-03-23
Abstract: PURPOSE:To attain block decomposition processing without any hindrance even at high speed reproduction and to suppress the increase in the quantity of hardware by applying simultaneously write and readout operation in the case of restoring the block order into the order of television scanning. CONSTITUTION:A series of an input data is supplied to a parallel processing circuit 2, where it is converted into a data series of 8-sample parallel and a data series of 4-sample of the output of the parallel processing circuit 2 is written in the 1st memory P1 and the 2nd emory P2. The 8-sample parallel data is readout of the memories P1, P2 simultaneously and fed to a series processing circuit 3 and the output data subjected to series processing by the circuit 3 is extracted at an output terminal 4. Thus, since the write/readout is applied in 8-sample parallel, the 4 sample each time is assigned to the write and readout with respect to one cycle of memory write/readout. Thus, the block decomposition processing at high speed reproduction is implemented without hindrance and the increase in the quantity of hardware is suppressed.

Title: Manufacture of titanium wire for electrode
Inventor: MASUKATA YOSHIKI
IPC: B21B1/16
Filed: 1988-03-23
Abstract: PURPOSE:To improve the product quality and reduce the cost by forming titanium or a titanium alloy stock into a round wire stock by hot rolling and drawing work and then finishing a section of the stock into a rectangular or a special form section by roll working. CONSTITUTION:A pure titanium or titanium alloy stock is formed into a round wire stock by hot rolling and is drawn, then the stock is finished into a product having a required sectional shape by use of one or more flat roll or grooved roll mills. Thus, shape working stages for a final sectional shape such as slitting, shearing, or machining are eliminated; further, generation of shredding remains and shavings is completely eliminated. The quality of titanium wire products for electrodes is improved because the wire surface is smoothly and uniformly finished in the roll working stage. The yield is improved by eliminating generation of scraps and the manufacturing cost is reduced by the yield improvement coupled with simplifying working stages.

Title: Light-emitting diode lighting circuit
Inventor: WATAZUMI TERUHIRO
IPC: H01L33/00
Filed: 1987-03-25
Abstract: PURPOSE:To allow an lighting circuit to be used in a high-precision position sensor or measuring equipment and to manufacture such a circuit in a low-cost simplified process by a method wherein a constant-voltage power source is provided and, to the output of the power source, a light-emitting diode and a temperature-compensating resistor are connected in series. CONSTITUTION:A variable resistor VR1 is connected to the non-reversible input terminal (+) of an operational amplifier OP and, to the non-reversible input terminal, a reference voltage VR determined by the variable resistor 1 is applied. An end of a resistor R1 is connected to the output of the operational amplifier OP, and the other end thereof is connected to the non-reversible terminal (-) of the operational amplifier OP and to the anode of a light emitting diode LED. Across the cathode and ground of the light-emitting diode LED, a temperature-compensating resistor R2 is connected. The operational amplifier OP and variable resistor VR1 constitute a power source for a constant voltage 100. In a light-emitting diode lighting circuit of this design, the forward current IF increases when the light emitting diode forward voltage VF decreases with the ambient temperature on the rise, which compensate for the reduction of the optical output. When the value to be presented by the temperature-compensating resistor R2 is properly specified, the high-precision optical output may be so regulated as to be of the same intensity.

Title: Heat pipe
Inventor: WATABIKI NAOHISA
IPC: F28D15/02
Filed: 1985-04-03
Abstract: PURPOSE:To prevent the failure of the operation of heat pipes by a method in which a container is divided into many layers, water is confined into each layer, and the diameter of the container is made smaller. CONSTITUTION:The outer container 1 of heat pipe consists of a heat receiving section 6 and a condensing section 5. Inner containers 2 of several heat pipe units are set in the outer container 1. Water as heat medium 3 for heat pipes is vacuum-injected into the container 2. The heat received by the heat receiving section 6 is transmitted to water 3 in the container 2 and the water is vaporized toward the condensing section 5 of the container 2. The actions are conducted to the next sections of the container 2 in order, and the heat is conducted to the condensing section 5. The lengths of the bottom 7 and the side face 7 of the container 2 are controlled to 1:1 for preventing the closing of the internal spaces of the container 2 by condensed water during the operation of the heat pipe. The amount of water in the heat pipe container 2 can thus be sufficiently reduced. Also, even during the operation of the heat pipe, the internal spaces of the container 2 are not closed by water, and therefore, even small-diameter heat pipes can be operated.
