Title: Laminated ceramic capacitor
Inventor: SUZUKI ICHIRO
IPC: H01G4/12
Filed: 1991-01-23
Abstract: PURPOSE:To prevent the thermal stress concentration of the dielectric corner part in outer electrode structure by making the lower layer of an outer electrode an electrode, which contains glass frit, and covering the conductive cover terminal corresponding to this lower layer with a conductive adhesive, with respect to the upper layer of this outer electrode. CONSTITUTION:For an outer electrode lower layer 3, it is made electrode paste, where an electrode material having Ag for its main ingredient and glass frit are kneaded to prevent the fusing property of solder, and this electrode paste is applied on the exposure face of the inner electrode 2 and it is baked to complete it. Next, using a thermosetting conductive adhesive 4, a metallic cap terminal 5 is bonded on the outer electrode lower layer 3, and is thermoset, thus the metallic cap type terminal 5 and the outer electrode lower layer 3 are junctioned. In case of solder mounting, even in the case of soaking a laminated ceramic capacitor wholly by dip method, the metallic cap-typed terminal 5 and the outer electrode lower layer 3 are not junctioned by solder, and it comes that the stress absorption to the thermal shock is performed through the thermoset conductive adhesive.

Title: Power system control device for vehicle
Inventor: KAMIYAMA ZENJI
IPC: F16H63/50
Filed: 1982-01-18
Abstract: PURPOSE:To save fuel consumption by a method wherein the output of the engine of the vehicle is controlled by the differential signal between an engine output command signal and an engine output measuring signal and the variable speed ratio of the engine is controlled by the differential signal between a signal obtained by the addition of an r.p.m. command signal and the above mentioned differntial signal for controlling the engine output, and an r.p.m. measuring signal so that the power system of the vehicle is controlled synthetically with respect to both the engine and a variable speed gear. CONSTITUTION:When the engine is accelerated through an acceleration pedal 6, the engine output command signal from a detector 7 and the engine r.p.m. command signal increase. However, the number of revolutions of the engine does not increase rapidly and therefore, the output of an air flow rate sensor 8 does not increase, too. Accordingly, there arises a difference in magnitude between the engine output command signal and the output signal from the sensor 8 with the result that a signal for increasing the opening degree of a throttle valve 10 is generated from a control device 9 and at the same time, the outut signal from an adder 13 increases further because the r.p.m. command signal and the output signal from the control device 9 increase altogether, so that the signal capable of increasing the variable speed ratio of the engine is applied on a variable speed gear adjusting device 15 from a variable speed gear control device 14. As a consequence, the engine torque and the vehicle speed increase, the output signal from the control device 9 comes close to zero and the output of the engine is stabilized. Further, the output signal from the adder 13 comes close to the engine r.p.m. command signal and the output signal from the control device 14 also comes close to zero, to thereby stabilize the variable speed ratio of the engine.

Filed: 1993-01-19
Abstract: PURPOSE:To prevent the gap between the resonance frequency and antiresonance frequency of piezoelectric vibrators from being narrow and to make the attenuation amount of a cutoff domain large in a wide band by letting a first piezoelectric vibrator be a serial element, letting a second piezoelectric vibrator fig a parallel element and alternately connecting the elements serially and parallelly. CONSTITUTION:The piezoelectric vibrator is a rectangular piezoelectric ceramic vibrator utilizing length vibration using a rectangular vibrator plate made of ceramic whose length is L, width is W and thickness is T (in this case, the relation of L>W>T is presumed). The rectangular pizoelectric ceramic vibrator is used as the serial element and electrodes 4 and 5 facing to each other are formed on the entire surfaces of the two side surface LXT surfaces 2 and 3 of a piezoelectric vibrator plate 1. Also, an arrow mark P indicates the direction of polarization. By this structure, the capacity of the elements can be made small without changing the gap of the resonance frequency and antiresonance frequency of the rectangular vibrator. Further, by utilizing the length vibration, a blocking band attenuation amount is enlarged and the filter of the wide band can be constituted.

Abstract: PURPOSE:To always obtain the coincidence between oscillation frequency and clock frequency and to simplify a constitution by using the 1st means which converts the voltage controlled oscillation frequency into voltage and the 2nd means which compares the output voltage of the 1st means with the voltage of a reference voltage source, then feeds back the output voltage to a VCO. CONSTITUTION:The phase difference between the input signal supplied to an input terminal 1 and the output signal of a VCO4 is detected by a phase comparator 2 and applied to the VCO4 via an LPF3 to control the oscillation frequency of the VCO4. A feedback loop consisting of a differentiating circuit 6, rectifying circuit 7 and a DC amplifier 8 is provided between an output terminal 5 and a control terminal of the VCO4. The circuits 6 and 7 of the feedback loop produce the DC voltage proportional to the oscillation frequency of the VCO4. This DC voltage is amplified by the amplifier 8 and compared with the reference voltage given from an input terminal 8' of the amplifier 8. Then the compared output voltage is fed back to the VCO4 to always obtain the coincidence between the oscillation frequency and the clock frequency. Thus the oscillation frequency of the VCO4 is held stably when the input signal is cut off.

Abstract: PURPOSE:To make it possible to start and accelerate an engine, smoothly, by compensating a basic ignition timing which is determined in accordance with the operating parameters of the engine, in accordance with compensating variables which are set in accordance with parameters indicating the temperature and load of the engine. CONSTITUTION:Upon operation of an engine, a CPU determines whether the engine rotational speed Ne is higher than a predetermined rotational speed (for example, 3,000rpm) or not when the cooling water temperature TW detected by a water temperature is lower than a predetermined value. If it is not, the basic spark advance is compensated with a compensating variable thetaTW. Meanwhile if it is so, determination is made on whether the absolute pressure value PBA in the intake-air pipe, detected by an absolute pressure sensor 14 falls in a range between predetermined upper and lower limits, or not. If it is so, a compensation value thetaTW is computed in accordance with two thetaTW-TW tables in a ROM27. This computation is performed in accordance with the absolute pressure PBA in the intake-air pipe which is calculated by a complementary calculation from two compensation values thetaTWil, thetaTWi2 obtained in accordance with the temperature TW, and the spark advance is computed in accordance with the thus obtained compensation variable thetaTW.
