Patent JP-H10106619-A (JP)
Title: Alkaline storage battery and its manufacture
Inventor: KOBAYASHI KOTARO
IPC: H01M10/30
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent capacity drop resulting from the decrease in the packed density of active material so as to enhance a high-temperature charging characteristic by adding a calcium compound to the electrolyte. SOLUTION: Addition of a calcium compound to an electrolyte enables a high-temperature charging characteristic to be enhanced efficiently with a small amount of calcium compound. The use of calcium phosphate as the calcium compound added ensures a sufficient effect although the reason is obscure, while the use of calcium oxide and calcium hydroxide cannot result in a sufficient effect. When an aqueous solution of potassium hydroxide with a concentration of 30 to 35wt.% is used as the electrolyte, the amount of calcium phosphate is 0.1 to 3.0wt.% for the aqueous solution of potassium hydroxide.  When the amount of calcium phosphate is less than 0.1wt%, a charge characteristic at high temperatures cannot be sufficiently enhanced, and, in excess of 3.0wt.% the battery internal pressure builds up, causing leakage of the electrolyte and a decrease in the electrolyte, resulting in degradation of cycle life characteristic.

Abstract: PURPOSE: To enhance accuracy in the detection of arbitrary phase shift and magnetic field by providing a plurality of magnetic circuit pieces having forward end parts spaced apart by a distance corresponding to an angle based on a predetermined phase shift of a detection signal. CONSTITUTION: A Hall ICfH1 has yokes b1, c1 arranged on the opposite sides of an arbitrary one of pole areas 25-28 such that a magnetic flux can flow in. A magnetic ring 24 is fixed to the rotary shaft of a rotor or a permanent magnet such that the radially outward pole of a magnetic ring 24 has the same polarity as that of the permanent magnet. Consequently, the magnetic ring 24 rotates in synchronism with the rotor and a detection signal being outputted from a magnetic detection element when the flux from a moving field flows into one magnetic circuit piece is shifted by an interval, corresponding to the distance between the forward end parts of respective magnetic circuit pieces corresponding to the angle based on a predetermined amount of phase shift, from a detection signal outputted from the magnetic detection element when the flux from other magnetic circuit piece flows in.  This structure enhances accuracy in the detection of arbitrary phase and field.

Filed: 1994-10-19
Abstract: PURPOSE: To reduce the number of multiplication devices to be used by performing the subtraction processing of digital video data and graphic data in advance, multiplying transparency data and adding the graphic data to the result. CONSTITUTION: The subtraction processing of the digital video data LD and the graphic data G is performed by a subtractor 6. To the subtracted result, the transparency data K for determining the mixing ratio of the video data and the graphic data are multiplied by the multiplication device 7.

Title: Optical deflector of surface acoustic wave
Inventor: NAKAMURA KENJI
IPC: G02B6/12
Filed: 1984-12-03
Abstract: PURPOSE:To make an external oscillating circuit unnecessary and to improve the purity and the stability of a high frequency signal for the oscillation of a surface acoustic wave by generating the high frequency signal for the oscillation of the surface acoustic wave by a positive feedback oscillator consisting of a closed loop including reed screen type electrodes for oscillation and wave reception. CONSTITUTION:Reed screen type electrodes 3a and 3b and an amplifier 5 constitute the closed loop, and the surface acoustic wave is propagated from the reed screen type electrode 3a in directions of arrows 11 and 12 when this closed loop is oscillated. The surface acoustic wave propagated in the direction of the arrow 11 deflects an incident luminous flux 8 of a thin film optical waveguide 2 and is absorbed by an absorbing material 13a. The surface acoustic wave propagated in the direction of the arrow 12 is converted to an electric signal by the reed screed type electrode 3b to become a positive feedback signal for oscillation of the closed loop. Since the oscillation level of the closed loop is approximately equal to the saturation output level of the amplifier 5, the saturation level of the amplifier 5 is set to level matched to a desired value to set the power of the surface acoustic wave oscillated from the reed screen type electrode 3a to this desired value.

Title: Monitoring of temperature of refrigerated goods and frozen goods and apparatus for implementing the same
Inventor: BARUTAA HORUTSUAA
IPC: G01K11/06
Filed: 1988-10-07
Abstract: PURPOSE: To prevent intentional alteration of indication comprehensively by an arrangement by arranging two tracers while shifting such that when at least one indicator is melted the indicator is subjected to gravitation and flows into other hollow part in a cavity. CONSTITUTION: Two single case type tracers 1, 2 are fixed to a cold-storage goods while avoiding common position. Indicators 4, 5 are frozen and when the tracer 1 is turned by 180 deg. at that position, the indicator 4 is located above and the indicator 5 is located below. When the tracer is fixed vertically to the cold-storage goods, the indicator 5 is held as it is even if it is melted but the indicator 4 is melted and flows down to the lower part in the cavity 3. Consequently, the indication can be prevented from being altered by turning down one tracer to cause gravitational flow down.

Filed: 1985-11-15
Abstract: PURPOSE:To realize a small-sized high performance low cost receiving/phasing part, by mounting a sampling circuit and a sampling time control circuit in the same IC with respect to the same receiving element. CONSTITUTION:A sampling circuit SA, a sampling time control circuit CG and a memory circuit Mo preliminarily storing data required in the variable control of sampling time are mounted in the same IC.

Further, a transmission synchronous signal 3 and a memory writing terminal 4 are provided. Because the terminal 4 is used only at the time of the manufacturing of a phasing circuit, the number of IC pins are reduced and the advantageousness in the miniaturization of IC is achieved.
