Title: Cooling apparatus using boiling heat transfer
Inventor: TERAGUCHI NOBUYUKI
IPC: H01L23/427
Filed: 1990-11-15
Abstract: PURPOSE:To completely take out a noncondensable gas and to prevent the cooling ability of a condenser from being lowered by a method wherein a guide passage one end of which is connected to a hole and the other end of which is opened upward is formed inside the condenser. CONSTITUTION:A coolant liquid 4 is boiled by heat at a semiconductor stack 5; it robs the heat of the semiconductor stack 5. The heat is changed to a high-temperature coolant vapor; it is passed through a vapor pipe 6a; it is guided into a condenser 6; it is cooled inside the condenser 6; it is condensed and liquefied; it is changed to a low-temperature coolant liquid; it is passed through a liquid pipe 6b; it is returned again to a container 3. When this operation is repeated sequentially, the semiconductor stack 5 is cooled well. Although the height of an outside box 1 is low and the mounting position of a pipe 7 is moved to the lower part, a noncondensable gas can be taken out easily to the outside form the side of the pipe 7 even when the gas stays at the upper part of the condenser 6 because the other end side of a guide passage 13 is opened at the upper part of the condenser 6. Thereby, it is possible to completely take out the non-condensable gas and to prevent the cooling ability of the condenser form being lowered.

Title: Output signal controller for business equipment
Inventor: OTANI MASAYUKI
IPC: G03G15/36
Filed: 1988-12-12
Abstract: PURPOSE:To simplify a control circuit by outputting a digital control signal to an output port at bits in a prescribed number, and using a serial signal converted by means of an output control means for the energizing control of output equipment. CONSTITUTION:A parallel/serial converting means 110 is connected to the output port of a digital control means 100. The converting means 110 has a means to convert the serial signal into a parallel signal and a latch means 120. The digital control means 100 generates a pulse at a constant cycle by a timing control circuit 130 in synchronization with the serial signal emerging at the time of outputting the signal to the output port. The pulses at the constant cycle are automatically generated by a prescribed number whenever the synchronizing signal outputted by the control means 100 emerges, and they are impressed to the converter 110 and the control means 100 by a signal generating means 130. Since a bit signal is used for the energizing control, when the number of pieces of the output equipment is large, the large number can be coped with only by increasing the number of the bits of the control means 100, and a circuit constitution can be simplified.

Title: Method of controlling operating range of robot
Inventor: WATANABE TORU
IPC: G05B23/02
Filed: 1987-12-14
Abstract: PURPOSE: To prevent the body of a robot from touching equipment lying within the operating range even if the robot is moved horizontally or rotated by setting an off-limit space within the operating space. CONSTITUTION: For the operation of a robot, its operating range ABCDEFGH is defined by its moving angles about axes forming the robot joints. A moving object having entered the operating range or fixed equipment installed in the operating range is detected by a detector arranged separately from a robot position detector. The detection results are used to set a closed space off-limits to the robot (x' to x", y' to y", z' to z"). When any working instruction is given to the robot, it is determined whether the working path intersects the closed space through operation. If this working path is found intersecting the space, the robot operation is immediately stopped to prevent the robot body from touching the equipment placed within the operating range.

Title: Ac power voltage detector
Inventor: TOMITA TAKASHI
IPC: H02M7/48
Filed: 1992-10-29
Abstract: PURPOSE:To stably and accurately detect the AC power source voltage by detecting directly the peak value of the power source voltage by a delay time equal to a half cycle of synchronization of the power voltage. CONSTITUTION:When the signal SA produced by a rectifier circuit 512 has a higher level than a reference signal VB, the output SB of a comparator 515 is turned to 1 and a counter 516 counts the clock signals. Then the output SB is turned to 0 when SA<=VB is satisfied. Under such conditions, the count value of the counter 516 is held on an output stage and cleared. At the same time, a CPU 514 reads the count value T5 of the counter 516. The time (T5-T3) during a period when SA>VB is kept is known from the value T5. The voltage peak level is defined as a T7 that adds the half time of the (T5-T3) to the rising edge T6 of the next SB. The CPU 514 reads the value of the signal SA in the time T7 via an A/D converter 517. Thus the AC power source voltage can be stably and accurately detected.
