Title: Production of heat exchanger having excellent corrosion resistance
Inventor: SHIMAJIRI YOSHIFUMI
IPC: B23K1/00
Filed: 1988-05-31
Abstract: PURPOSE:To prevent the generation of degradation in function by dislodgment of fins and to improve corrosion resistance by using a specific alloy for the core material of brazing sheets which constitute the fins, forming Zn coating layers on the surfaces of tubes and subjecting both to flux brazing. CONSTITUTION:The brazing sheet formed by cladding a brazing filler metal consisting of an Al-Si alloy to at least one face of the core material consisting of an Mn alloy contg., by compsn. weight ratio, of 0.01-1% Al and 0.7-1.8% In is used as the fins 2. The tubes 2 made of the Al previously formed with the Zn coating layer on the outside surface or the alloy thereof are used. The corrugated fin type heat exchanger 3 is assembled by interposing the fins 1 between the straight pipe parts of the respective tubes 2. The respective heat exchanger assemblies are immersed in the liquid suspension of a fluoride flux to coat the flux on the surfaces thereof. The assemblies are then heated in an inert gaseous atmosphere and are thereby brazed. The time before the fins are dislodged and the time before through-holes are opened in the tubes are prolonged in this way.

Title: Output buffer circuit
Inventor: TAMAMURA MASAYA
IPC: H03K19/086
Filed: 1989-05-29
Abstract: PURPOSE:To eliminate distortion of an output waveform by providing a means drawing a current nearly equal to a collector current when an output transistor(TR) is turned on from a prescribed power line while the output TR for one output is turned off. CONSTITUTION:When an input signal is at an 'L' level, a collector current IC3 of an output TR T3 is drawn from a prescribed power line 2. When an input signal is at an 'H' level, a current IC4 (current equal to the collector current IC3 of the TR T3) is drawn from the prescribed power supply line 2 by a current extraction means 4. Thus, the current flowing via the prescribed power supply line 2 is almost made constant regardless of the change in an input signal. As a result, the potential fluctuation of the prescribed power supply line 2 is evaded to prevent distortion of the output waveform.

Title: Device for contact detection
Inventor: KOSUGE YUSUKE
IPC: G01B7/00
Filed: 1991-06-07
Abstract: PURPOSE:To stabilize the positioning of a locator and to increase the precision in contact detection by supplying air to a contactor from a first air path through a radial exhaust passage of the contactor and by supplying part of the air to an air receiving part of a moving body from a second air path. CONSTITUTION:Pressurized air or the like is led to an exhaust port 21 from a first air path 25 through a radial exhaust passage 22 and jetted outside. Then cut chips and the like sticking on the fore end of a contactor 17 and on a substance W to be measured are removed. When the pressurized air or the like flows into a corner space 18C on the contactor side of a jutting part of a guide 23 of a tubular housing 2, a jutting part 18 of a contact body 3 is subjected to a pressure and is to move onto the opposite side to the contactor 17. Thereby a moving body 4 is pressed to move in the direction of the other end side of the housing 2. On the occasion, part of the air flows into an air receiving part 34 of the moving body 4 from a second air path 29. Thereby the pressure of the moving body 4 moving onto the other end side of the housing is canceled through the intermediary of the air receiving part 34. Being kept in a correct attitude, accordingly, the contactor 17 comes into contact with the substance W to be measured.

Abstract: PURPOSE:To make it possible to obtain a great forward moving force without decreasing the meshing width when a pinion is moved, by arranging a projected section to a lever at a point displaced toward the fulcrum point from the end that is a first action point, the projected section serving as a second action point. CONSTITUTION:A lever 2 is provided with a projected section 2d at a point displaced toward the fulcrum point 2a from the end 2c that is a first action point, and the projected section 2d abuts against a structure section having a pinion 4a before the abutting against the end 2c to serve as a second action point in the initial stage of the actuation of the lever. The lever ratio that will be determined by the projected section 2d is made smaller than the lever ratio determined by the end. Accordingly, without decreasing the meshing width of the pinion 4a with a ring gear 5, a greater forward moving force is available when the pinion 4a is moved to the state of the pinion movement position.

Title: Arithmetic circuit
Inventor: ITO AKIRA
IPC: G06F17/10
Filed: 1989-05-30
Abstract: PURPOSE:To attain the continuous cumulative arithmetic processes in order to increase the computing speed and at the same time to carry out a rounding process in a compact circuit constitution by securing the constitution of a selection circuit so as to select the initial value in place of the cumulative value obtained via an adder in response to an initialization signal and to output the selected initial value to the adder. CONSTITUTION:When the cumulative addition value is obtained in a single cumulative arithmetic cycle, an initialization signal is inputted to a selection circuit 22 at the start of a cumulative arithmetic. Thus the circuit 22 selects the initial value and outputs it to an adder 23. The adder 23 adds the received initial value to the input value and stores the result of addition in an accumulator 21. Hereafter the circuit 22 selects the cumulative value received from the accumulator 21 to add it to the input value. Thus no independent clock cycle is needed to clear the cumulative value of the accumulator 21. As a result, the arithmetic continuity is maintained and at the same time the computing speed is increased.

Abstract: PURPOSE:To prevent misjudgment by providing a switch for applying a voltage to a coil to be measured, a counting means that counts a time period from the time when a voltage is applied to when a counter electromotive force is lowered to a prescribed value, a memory means and a comparing means. CONSTITUTION:A NAND gate 7 is controlled such that the passing or blocking of a clock CLK inputted to a clock terminal 8 is determined by inverting it in accordance with an output of an operational amplifier 4. A counter 9 counts the inverted clock CLK. A counting means consists of the amplifier 4, NAND gate 7, counter 9 and the like. A latch circuit 10 stores the counted value of the counter 9. A value comparator 11 compares a present counted value of the counter 9 with the counted value stored in the latch circuit 10. Thereby, it is possible to discriminate the increase or decrease of an inductance of a coil 1 to be measured.
