Title: Heat pipe air preheater
Inventor: OOSHIMA TETSUO
IPC: F28D15/02
Filed: 1985-06-11
Abstract: PURPOSE:To permit to use water as an operating liquid by a method wherein first stage heat pipe is provided between exhaust gas and the upstream side path of air while second stage heat pipe is provided between the exhaust gas and the downstream side path of the air, in order to reduce the maximum operating temperature of the heat pipe. CONSTITUTION:In the first stage heat pipe 38, high-temperature exhaust gas contacts with high-temperature side evaporating section 39 and low-temperature air, not yet heated, contacts with low-temperature side condensing section. In the second stage heat pipe 42, the exhaust gas, whose temperature is reduced by the high-temperature side evaporating section 39 of the first stage heat pipe 38, contacts with the high-temperature side evaporating section 43 and the air, heated by the low-temperature side condensing section 40 of the first stage heat pipe 38, contacts with the low-temperature side condensing section 44. According to this constitution, the maximum operating temperature of the heat pipe becomes low and water can be used as the operating liquid of the heat pipe. Accordingly, expensive corrosion resistant material is not necessitated to be used for the heat pipe while the thickness of the heat pipe may be thinned and whereby the weight of the heat pipe may be reduced.

Title: Control device for resistance spot welding machine
Inventor: SUZUKI KANJI
IPC: B23K11/24
Filed: 1983-07-13
Abstract: PURPOSE:To detect the abnormal short circuiting on the secondary side such as secondary cable of a welding transformer and to prevent welding defects and the like by turning on a start switch to conduct current while a welding gun is open and enabling detection of the current value on said secondary side in this stage. CONSTITUTION:Plural kinds of welding conditions are selected with, for example, a control device, by start switches 1-4. If the switch 2 is turned on here, interlocking contact points a2-e2 are closed. As a result, the preset preliminary pressing time, welding time, welding current and holding time are inputted and set from setters 7, 10, 9, 13 to respective circuits 6, 8, 12, 11. A driving circuit 14 for a pressurizing valve is turned on at the same instant, by which a welding gun is closed and welding is accomplished by the on operation of the circuit 6 and others. On the other hand if the switch 5 is turned on in the stage of detecting short circuiting, the circuit 6, etc. are inputted and set and the other contact points e5 are closed, by which a detecting circuit 15 is turned on and the welding gun is held open. The circuit 15 passes the welding current I5 until welding time W5 passes by after the lapse of the preliminary pressing time S5. The presence or absence of the short circuiting on the secondary side is thus detected with a current detector 17.

Title: Sweep end signal generator
Inventor: NUMAYASU YOSHIO
IPC: G09G1/14
Filed: 1982-07-21
Abstract: PURPOSE:To generate a sweep end signal with high precision by setting a regularly octagonal boundary circumscribed with a round CRT screen when an electron beam is swept by polar coordinate deflection, and ending the sweeping when the mathematical condition of sweep positions beyond the boundary is satisfied. CONSTITUTION:The coordinate position (X, Y) of a swept electron beam is found by conversion to orthogonal coordinates and absolute values ¦X¦ and ¦Y¦ are inputted to comparators 10 and 12 and a digital adder 14. When a sweep at an antenna azimuth angle thetaA reaches a point A on the boundary of a square 3 shown by a solid line, the output (¦X¦+¦Y¦) of the adder 14 is equal to the reference 2<1/2>.R of a digital comparator 16 and when an addition output exceeding 2<1/2>.R is obtained, the comparator 16 generates an output to operate a sweep end pulse generator 20 through an OR circuit 18; and a sweep end pulse is supplied to a sweep signal generating circuit part and the sweep ends. Consequently, the sweep is carried out excessively only at a part shown by slanting lines, so power consumption is saved and sweep time loss is eliminated, improving the precision of the ending of the sweep.

Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To easily control the transition time of each edge by comparing the edge phases with each other between a clock signal, having its controlled phase and a delayed clock signal and performing the control to satisfy a prescribed relation between both edges. SOLUTION: A phase delay circuit 12 delays a clock signal CLK1 by a prescribed amount. The phase value to be delayed is 180 degrees, that is, the signal CLK1 is delayed by only T/2, as long as the signal CLK1 has a cycle T. A phase comparison circuit 13 compares the phases with each other between the leading edge of the signal CLK1 and the trailing edge of a delayed clock signal CLK2 and then controls a phase control circuit 11, so as to secure the same timing between both edges. Conversely, the phases are compared with each other between the trailing edge of the signal CLK1 and the leading edge of the signal CLK2, and the circuit 11 is controlled to secure the same timing between both edges. With such a control, equality is established between a high period Thigh and a low period Tlow of the signal CLK1.

Title: Ground fault detecting method for direct current parallel feeding system

IPC: G01R31/02
Filed: 1989-05-22
Abstract: PURPOSE:To detect a current difference generated when an AC-side cable run is grounded and to detecting ground faults by system of AC-side cable runs by grounding the plus side and minus side of a DC cable run by impedance elements respectively. CONSTITUTION:One electric feeding system 1 for AC input consists of a three- phase full-wave rectifier 3, a breaker 11, a current transformer 15 and a leak relay 17. Further, resistances 13 and 14 common to respective electric feeding systems are the impedance elements for allowing ground fault currents to flow. Then the detection signal of the current transformer 15 which detects the current difference between a going current and a return current flowing through each couple of going and return paths of a DC cable run releases the breaker 11 through the operation of the leak relay 17 which operates according to the current difference, thereby cutting off the DC output from the rectifier 3. Namely, the current difference is generated only between the going and return currents of the output current of the rectifier of a system where the ground fault is caused to securely detect the ground fault, system by system.
