Title: Load transducer
Inventor: KIMURA ICHIJI
IPC: G01L1/00
Filed: 1986-09-25
Abstract: PURPOSE:To obtain a weighed value signal with high resolution by measuring the attenuation required time of the output signal of a coupler provided to a cavity resonating housing and obtaining the weighted value signal corresponding to a load. CONSTITUTION:When the load G is placed on the cavity resonating housing 10, its internal shape deforms according to the load G and the housing 10 varies in Q according to the deformation. The attenuation rate of a burst wave when constant energy is applied to the cavity resonator is in inverse proportion to the Q of the housing 10. For the purpose, an attenuation time measuring circuit 15 measure the attenuation time of the burst wave to detect variation in Q, i.e. the load value. Thus, the extent of the elastic variation of the resonating housing is detected as the Q variation of the resonating housing, so a lever is unnecessary unlike a crystal oscillation type and the fundamental oscillation frequency is high, so the weighted value signal with higher resolution than the crystal oscillation type is obtained.

Abstract: PURPOSE:To eliminate load-related errors attributable to warp in a ceramic substrate, external waviness, protrusion of conductive material in through-holes, dimensional errors of input/output electric junction pins, etc., for the realization of highly reliable junctions of a uniform adhesion strength by a method wherein every one of the pins are supplied with their respective loads, independent from each other, when they are bonded to a ceramic substrate with solder. CONSTITUTION:At a portion of a ceramic substrate 2 to experience soldering, a chromium film 4 and palladium film 5 are deposited, in that order, by spattering. The ceramic substrate 2 is then inserted into a carbon jig 1 for soldering, and is positionally aligned to a junction pin 7 applied beforehand with a soldering material 6. Next, for an increase in adhesion strength of the junction pin 7, a load 9 is imposed on the junction pin 7 from above, and then soldering is accomplished. Each junction pin 7 should be given its own load 9 independently. This independent-load method ensures an equal load on each pin, which results in a multilayer ceramic substrate provided with junction pins less varied in adhesion strength.

Abstract: PURPOSE:To prevent lowering of volume efficiency due to leakage of fluid and lowering of mechanical efficiency due to a friction loss between an outer rotor and a housing and to prevent the generation of noise by a method wherein a chamber fronting on the outer peripheral part of the outer rotor of a pump is communicated with an intertooth chamber formed on the inner periphery of the outer rotor. CONSTITUTION:When an intertooth chamber 5 positioned between a suction port 130 and a delivery port 140 is communicated to the suction port 130, the internal pressure of the intertooth chamber 5 (the pressure of an inner peripheral part 42 of an outer rotor 4) is reduced to a low value. The internal pressure of a pressure balance chamber 180 (the pressure of an outer peripheral part 42 of the outer rotor 4) is also reduced to a low value through first and second communicating grooves 191 and 192. By communicating the intertooth chamber 5 with the delivery port 140, the internal pressure of the intertooth chamber 5 is increased to a high value, and the internal pressure of the pressure balance chamber 180 is also increased to a high value. Thus, the pressure of the inner peripheral part 42 of the outer rotor 4 and the pressure of the outer peripheral part 41 can be kept in a balancing state, fluid from the intertooth chamber 5 can be prevented from leakage, and a friction loss between the outer rotor 4 and a housing 100 can be prevented from an increase, resulting in improvement of the volume efficiency and the mechanical efficiency of a pump.

IPC: H04M1/274
Filed: 1988-09-14
Abstract: PURPOSE:To facilitate redialing by storing inputted opposite numbers in the order of access, weighting the data depending on number of dialing and clearing sequentially the minimum data. CONSTITUTION:Opposite number data from an operation section 1 are stored in a number registration section 6 by a control section 4 in the input order or the access order of dialing order. Moreover, the weighting of number of dialing is added and the result is stored in a number storage section 7, in which the data with minimum weighting is cleared sequentially resulting in being aborted completely. When two digits in an opposite number are entered depending on the content of the number registration section 6 and the number holding section 7, the control section 4 reads out the relevant number and gives it to a signal generating section 2. Thus, automatic dialing for redialing and abbreviated number dialing is attained.

IPC: H04B10/00
Filed: 1983-12-05
Abstract: PURPOSE:To obtain a photodetection signal equalizing circuit which is suited to miniaturization, conversion into an LSI, etc., by providing a window which limits incident light quantity to have a prescribed ratio for the light quantity to be supplied to each photodetecting element. CONSTITUTION:Light is irradiated to a photodetecting part 12 from an optical fiber via a light shielding part 16. In this case, the light quantity supplied to each photodetecting element 17 is limited by a photodetection window 18. Here the photodetection quantity to each element 17 per unit area an the opening area of the window 18 are set a prescribed ratio, respectively. The element 17 converts the light electric signals and delivers them. Each of these delivered signals is supplied to each corresponding delay stage of a transfer part 13. Each delay stage is driven synchronously with the clock given from a drive signal part 11 and transfers successively the input signals toward an output with superposed addition with signals of the preceding stage. This can realize exactly a input weighting type transversal filter.
