Patent JP-H03215916-A (JP)
Title: Method for formation of electrode and electronic part using it
Inventor: ISHIKAWA MARIKO
IPC: H01G4/12
Filed: 1990-01-19
Abstract: PURPOSE:To made it possible to obtain a low-priced basic metal electrode by a method wherein the particle surface of basic metal oxide powder is coated with precious metal of the specific wt.% of the base material, and after the powder has been calcined in the air, it is reduced in a hydrogen atmosphere. CONSTITUTION:The particle surface of basic metal oxide powder is coated with a prescribed wt.% of precious metal of substrate material, and after calcination in the air, it is reduced in a hydrogen atmosphere. At this point, it is unnecessary that the entire substrate material is uniformly coated with the covering metal, and it is sufficient that the coating is performed in the degree in which the diffusion of the substrate material has no influence on the characteristics of a ceramic part, and by lowering the temperature of sintering using suitable frit, the effect of diffusion prevention can practically be obtained even with 5.0wt.%. On the other hand, when the quantity of the covering metal exceeds 15.0wt.%, the effect of reduction in quantity of the covering metal used is lessened. As a result, a highly efficient basic metal electrode can be obtained at low cost.

Title: Deflecting device of solid-state image pickup element
Inventor: TANUMA CHIAKI
IPC: H04N5/335
Filed: 1982-01-29
Abstract: PURPOSE:To obtain a deflecting device of solid-state image pickup element which can be produced in an easy way of production with excellent reliability and mechanical strength, by fixing the 1st bimorph oscillator to the end face of one side of a basement and a solid-state image pickup element and the 2nd bimorph oscillator to the end face of the other side of the basement and the solid-state image pickup element respectively to apply an electric field to these bimorph oscillators and then moving with a shift the basement and the solid- state image pickup device in parallel to each other. CONSTITUTION:An electric field is applied to bimorph oscilators 21 and 22 so that they are bent to the right side respectively, and as a result a solid-state image pickup element 11 moves together with the oscillators 21 and 22 to the right side and in parallel to a basement 30. In this case, the element 11 never tilts to the basement 30 compared with a state obtained before the electric filed is applied for deflection since the element 11 moves in parallel to the basement 30. In case a backward electic field is applied, the element 11 moves horizontally and to the left side. Thus the deflection is attained. A high level of image resolution is obtained for a solid-state image pickup device owing to its consecutive operation.

Title: Active filter
Inventor: TANAKA MASAAKI
IPC: H03H11/12
Filed: 1988-01-22
Abstract: PURPOSE:To decrease the number of components around an IC by varying the sum or the ratio of currents of constant current source of 1st and 2nd differ ential amplifier circuits in response to the sum and difference of two digital signals. CONSTITUTION:The sum (Df0+DQ) of two digital signals (Df0), (DQ) and a difference (Df0-DQ) are obtained and the sum (I1+I2) of the constant currents I1, I2 of the 1st and 2nd difference amplifier circuits 31, 32 or the ratio I1/I2 is varied to change the center frequency f0 of the Q. Since no external compo nent is required for the IC to control the center frequency f0 of the Q, the number of components around the IC is decreased. Since the dispersion in the filter characteristic attended with the dispersion in the element characteristic in the inside of the IC is corrected by the electric processing to vary the digital signals Df0, DQ, the filter IC characteristic is easily controlled.

Title: Vibrationproof support device
Inventor: HASEGAWA KAZUNORI
IPC: G11B33/02
Filed: 1986-01-24
Abstract: PURPOSE:To improve the vibrationproof performance of a product by sealing a viscous body in a rubber container where a mixer is projected to an oil cut wall and its inside to absorb the vibration of the rubber container by viscous friction produced between said body and the mixer. CONSTITUTION:Horizontal vibration exerted on a housing 21 is delivered to a product main body 22 via a rubber container 11 and in this case, relative displacement is caused between the housing 21 and the product main body 22 to deform an elastic deforming part 12b of the oil cup wall 13. In this case, the mixer 14 is fluctuated to mix silicon oil 18, viscous friction is generated between a wing 15 and the silicon oil 18 and it acts on a direction suppressing the relative displacement and since the internal loss is generated by the elastic deforming part 12b of the oil cut wall 13 at the same time, the horizontal resonance magnification is suppressed. Further, the vertical vibration is delivered to the product main body 22 via the rubber container 11 and since no viscous friction is caused between the wing 15 and the silicon oil 18, the vibration transmission characteristic depends on the resonance frequency of the elastic deformation part 12b of the oil cup 13. Thus, the vibration capability is improved.

Abstract: PURPOSE:To prevent a recording image from deteriorating by providing a transparent plate which impedes air from flowing between a light source and an information light output terminal for outputting write light. CONSTITUTION:The opening part of a housing body 6 on the side of a convergent image forming element 3 is closed with a transparent plate 11 and a heat insulation plate 10 is fitted so as to open and close the upper part of the housing body 6.

Abstract: PURPOSE:To make idling stabilization easily attainable by calculating the illustrated mean effective pressure and its variation at each one cycle, and compensating the fuel injection quantity so as to converge this variation into the upper limit variation. CONSTITUTION:A controller bearing the above caption sets a fundamental controlled variable of an idling speed control(ISC) valve 6 from a water temperature detected value by a fundamental valve controlled variable setting means 33, while it compensates the fundamental controlled variable on the basis of a relative value of each output signal out of a desired speed setting means 19 and a speed detecting means 20 by a valve controlled variable feedback compensating means 21. In addition, it controls the ISC valve 6 in accordance with the valve controlled variable after compensation. In this case, indicated mean effective pressure at each one cycle is calculated from an output value of a cylinder internal pressure sensor 10 by a indicated mean effective pressure calculating means 23, while the variation is also calculated by a variation calculating means 24. Then, a fuel injection quantity set by a fuel injection quantity calculating means 31 is made so as to becompensated by a compensating means 25 so as to converge the said variation on a set upper limit desired variation within the range where a combustion state at the time of idling is stabilized.

IPC: B41J2/365
Filed: 1986-01-23
Abstract: PURPOSE:To contrive a higher printing quality, by supplying a thermistor with an electric current proportional to an electric current passed to a printing head, simulating a heat accumulation condition, and controlling heat on the basis of the result of the simulation. CONSTITUTION:Resistance heat generating elements 1 are provided in the form of a 24-pin head. A head-driving circuit 2 converts printing data sent from a controlling part 3 into 24 parallel data DATA1-DATA24. An electric current is passed to the element while a STRB line is '1'. On the other hand, the controlling part 3 counts the number of '1' among signal lines for DATA1-DATA 24, and sets a count value corresponding to the number on a timer 4. For a period of time corresponding to the count value thus set, the timer 4 functions to pass an electric current Is to a resistor 6 and a thermistor 7 through a driving circuit 5. As a result, the thermistor 7 generates a quantity of thermal energy proportional to the square of the number of dots printed. The controlling part 3 reads a variation in the resistance in the thermistor 7 as a voltage value, and the result is fed back through varying the pulse width of a STRB signal to the head-driving circuit 2.
