Patent JP-S5618730-A (JP)
Title: Electronic balance
Inventor: YANO SHIYOUZOU
IPC: G01D7/00
Filed: 1979-07-24
Abstract: PURPOSE: To faciliate and accelerate measuring operation and heighten the accuracy of measurement, by displaying the quantity of variation in an indicated zero point as apparently zero if the mean value of the variation is within an allowable range when the variation is stabilized within an allowable width.  
     CONSTITUTION: When no piece is no a balance 2 and the minute output signal Dr of an A/D converter 4 is applied to a stabilization detecting comparator 20, the signal is stored into a sampled value memory register 23 by the comparator at every sampling. The comparator 20 compares the signal Dr with stored values within a time set by an averaged stabilization time setting unit 21. If the stored values exceed an allowable fluctuation, width, all the stored values are erased. Subsequently, sampling and comparison are repeated. When it is found out that none of stored values exceeds the allowable fluctuation width, these stored values are applied to a calculation and data control unit 9 which averages the values. A minute range detection comparator 7 works so that the averaged value is indicated on a digital display unit 5 if the average value is out of an allowable minute range but apparent zero is indicated on the display unit if the average value is within the range.

Inventor: HAYASHI TAKAHIRO
IPC: F25B13/00
Filed: 1991-04-24
Abstract: PURPOSE:To finely control an expansion valve by calculating plural times a target valve travel of an indoor side expansion valve according to various parameters, selecting the opening in response to the magnitude of supercooling degree by fuzzy inference means, and controlling the valve travel of the valve. CONSTITUTION:The room heating controller for a multichamber type air conditioner comprises overcooling degree detecting means 18a, room temperature detecting means 19a and temperature setting means 20. First target valve travel calculating means 22 calculates a first target valve travel S1 of an indoor motor- driven expansion valve 17 from a deviation between a detected room temperature value and a target temperature. Second target valve travel calculating means 23 calculates a second target valve travel S2 of the valve 17 from a detected overcooling degree value. The calculated results are input together with the detected overcooling degree value to fuzzy inference means 26, which selects the valve travel S2 if the overcooling degree is small, the valve travel S1 if it is intermediate and the valve travel S2 if it is large. The valve travel of the valve 17 is controlled based on the selected valve travel through valve travel control means 28.

IPC: B23K7/06
Filed: 1989-04-14
Abstract: PURPOSE:To prevent slag from being scattered to the end face side by melting the surface to be scarfed up to the proximity of an edge by a nozzle for preheating, allowing an oxygen injection flow to collide against the end face, maintaining split flows in advance and moving it to the preheated surface to be scarfed to start scarfing. CONSTITUTION:A fire flow 9 is injected to the surface 5 to be scarfed of steel 3 from the nozzle 7 for preheating of a scarfing device 20 to start preheating and a molten layer 13 is generated on the interval up to the edge 6. The oxygen injection flow 10 is allowed to collide against the end face 4 of the steel 3 from a nozzle 1 for scarfing and split into two flows 11 and 12 in advance and the nozzle 1 for scarfing is moved in the longitudinal direction of the steel 3 and the collision surface 2 is shifted to the molten layer 13. Since the edge 6 side split flow 12 of the oxygen injection flow 10 is always maintained and shifted to the molten layer 13, it is perfectly prevented that the molten slag is caught up in the tip face 4 side and scattered and while the whole quantity of slag being blown off to the surface 5 to be scarfed of the unscarfed side in front, scarfing is carried out smoothly and satisfactorily.

Title: Method for detecting abnormality of measured data of electric power system
Inventor: FUKAYA MITSURU
IPC: H02J3/18
Filed: 1984-05-14
Abstract: PURPOSE:To decide exactly whether an abnormality exists or not by deciding that the abnormality exists when the difference of an apparent power calculated from effective and reactive powers detected in a system, and an apparent power calculated from a voltage detected in the same way exceeds a prescribed value. CONSTITUTION:An apparent power PL is derived by an expression from the respective differences P3=P1-P2, Q3=Q1-Q2 of an effective power P1, and a reactive power Q1 flowing into a terminal T1 of an electric power equipment having an impedance R+jX, and an effective power P2 and a reactive power Q2 flowing out of a terminal T2. Also, a loss PV=(V1-V2)I1 is derived from voltages V1, V2 and a current I1 of the terminals T1, T2. Moreover, a difference of losses derived from a calculation of two kinds, P0=¦PL-PV¦ goes to zero ideally, therefore, when the difference P0 of losses exceeds a range prescribed in advance, it is decided that the equipment is abnormal.

Title: Clamping circuit
Inventor: TATEISHI MICHIKO
IPC: H03M1/12
Filed: 1990-04-10
Abstract: PURPOSE:To reduce an error and to execute clamping with high accuracy by bringing two amplifiers and an A/D converter to necessary connection. CONSTITUTION:When a switch is turned on at the time of clamping, a reference voltage by a power source 6 of a reference potential of an A/D converter 7 of the same potential as a + side input is supplied to a - side input of an amplifier 5 through an amplifier 3, and inputted to the converter 7, as well. On the other hand, a capacitor 2 is charged to a voltage by which an output of the amplifier 3 becomes the reference potential. In this state, when the switch 4 is turned off and clamp voltage is inputted from a terminal 1, an input voltage multiplied by the gain of the amplifier 3 and a reference voltage which is not multiplied by the gain are inputted to the converter 7. Accordingly, at the time of clamping, an error to the reference voltage of an input of the converter 7 becomes small and clamping is executed with high accuracy.

Title: Judgement of propriety of electrolyte quantity held in fuel cell
Inventor: ITO KOJI
IPC: H01M8/04
Filed: 1987-04-17
Abstract: PURPOSE:To make it possible to judge propriety of an electrolyte quantity through a simple operation by connecting a pure hydrogen gas supply source to a fuel gas supply line, and switching fuel gas from reformed gas to pure hydrogen gas at an appropriate timing during operation so as to compare the output voltage prior to the switching with that posterior to the switching. CONSTITUTION:Reformed gas is supplied to a cell body 1 in normal operation. Then, a valve 3a is closed to stop supply of reformed gas by aiming at an appropriate timing and simultaneously a valve 7 is opened to switch the fuel gas to be supplied in the cell body from reformed gas to pure hydrogen gas and also a cell output voltage prior to the switching and that posterior to the switching are measured by a potentimeter 8 and compared with each other. Hereat, if the output voltage posterior to the gas switching to pure hydrogen gas is higher than that prior to the gas switching, it is judged that an appropriate quantity of electrolytic liquid is held. On the other hand, if the output voltage at the time of supplying pure hydrogen is lower than that at the time of supplying reformed gas, it is judged that the quantity of electrolytic liquid is short, thus enabling correct decision of proper timing of supplying electrolytic liquid.

Abstract: PURPOSE:To enable a laser oscillation whose output is stable for a long time possible, by providing gas tanks and a regenerator and by regenerating a deteriorated  laser gas. CONSTITUTION:Fresh laser gas is filled in a reservoir tank 48, and a reservoir tank 47 is vacant for replacing. The used laser gas in a laser generating portion is transfered into the tank 47 via a valve 41, a vacuum pump 43 and a valve 45. Then, fresh gas in the tank 48 is introduced into the gas laser generating portion via a valve 46, a vacuum pump 44, and a valve 42, the generating portion is  operated again, and the laser oscillation is restarted. At the same time, the gas in the tank 47 is refined and regenerated in a gas regenerating device 50 via valves 51A and 51B, and reserved for the next gas replacement. Since the regenerating device 50 is provided outside a frame 30 and the regenerating device 50 is provided outside the frame 30 and independent of the laser generating portion, and the operating temperature can be freely and accurately set when catalyst is used, the gas can be regenerated at the maximum regenerating efficiency which the catalyst can display.
