Title: D/a converter
Inventor: SAGA RYOHEI
IPC: H03M1/74
Filed: 1986-03-17
Abstract: PURPOSE:To facilitate the management of dimensions and the optimized layout design by arranging the emitter area of bipolar transistors (TRs) up to n-th transistor into one kind and providing a correction current source causing a voltage division in a resistance ladder to arrange up to n-th emitter potentials to be equal. CONSTITUTION:The emitter area of the bipolar TRs Q1-Qn is arranged the same. The bipolar TRs are connected to the resistance ladder consisting of serial/parallel connection of two kinds of resistors R, 2R having a resistance ratio of 1:2. Thus, the bipolar TRs Q1-Qn give a shunt current (I/2-I/2<n>) weighted sequentially according to a a/2 power of series sequentially to a corresponding current branch. On the other hand, the emitter area of the (n+1)th bipolar TRQapprox.=dn+1 is selected twice and its emitter is connected to the n-th current branch of the resistance ladder 1 via a resistor Rx.

Title: Radio receiver for vehicle
Inventor: FUKUHARA HIROSHIGE
IPC: H01Q1/12
Filed: 1981-04-17
Abstract: PURPOSE:To suppress the detuning of a radio receiver for a vehicle, the generation of a beam noise, and the generation of distortion by varying the length of a receiving antenna according to the intensity of a received radio wave. CONSTITUTION:When a radio wave has enough intensity to be covered by normal AGC, turning on the power source of a radio receiver permits a motor controlling circuit 20 to drive a motor 19, and the length of a receiving antenna 10 is maximized. When a vehicle runs into an area where the received radio wave is intense, e.g., right under a transmitting antenna, the reception input increases and the output of an AGC circuit 18 connected to the output side of a detecting circuit 15 also increases to decrease the gains of a high frequency amplifying circuit 11 and an intermediate frequency amplifying circuit, but when an AGC voltage rises above a reference value, the motor controlling circuit 20 drives the motor 19 to shorten the length of the receiving antenna 10.

Abstract: PURPOSE: To eliminate a source of trouble in a hydraulic pump and to enable lengthening of a pump life, by a method wherein a protection device, which acts as a buffer against a pressure shock being exercised upon a hydraulic pump and being applied from an accumulator side immediately after a motor starts, is mounted.  
     CONSTITUTION: An oil, which is discharged from a hydraulic pump 7 immediately after starting, flows into an oil chamber 21 through an oil line 8 and through an inlet port 20, a throttle part 23, an oil hole 22, which are located in a protection device 16, and returns into an oil tank 14 through a drain port 25. As a motor 10 accelerates its rotation speed, a discharge amount from the hydraulic pump 7 increases, and with the increase in the discharge amount, a pressure P 1  in the inlet port 20 increases. Or, the hydraulic pump 7 is gradually increased in the discharge pressure in proportion to a rotation speed (v) of a motor as shown in the solid line in a drawing. As a result, a pressure shock against the hydraulic pump 7 from an accumulator 12 side is substantially relieved, and a pump life can be lengthened.

Title: Piezoelectric actuator
Inventor: KAMEYAMA TSUTOMU
IPC: H02N2/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To cut down the number of the parts of a piezoelectric actuator and improve its workability when attaching it onto a board, by supporting the peripheral edge of its vibrating plate through metallic rings to provide its vibrating plate in its synthetic-resin case, and by forming integrally with the case the supporting legs for attaching the case to the board. SOLUTION: When providing a vibrating plate 2 in a case comprising synthetic-resin lower and upper cases 3, 4, the peipheral edge of the vibrating plate 2 is sandwiched between metallic rings 5, 6. Then, a supporting legs 31 for attaching the lower case 3 to a board 14 are formed out of the synthetic resin integrally with the lower case 3. Accordingly, with the complete machining accuracies of the sandwiched surfaces of the vibrating plate 2 without bringing any friction into the sandwiched surfaces, a piezoelectric actuator having a stable vibrating characteristic can be manufactured with a good workability. Also, the thermal expansion coefficients of the inner rings 5, 6 can be made nearly equal to the one of the vibrating plate 2, and, it can be prevented that the sandwiched atate of the vibrating plate 2 is changed by the temperature of the actuator to change largely the vibrating characteristic of the vibrating plate 2.

Inventor: TAMURA KUNIO
IPC: G01R31/26
Filed: 1991-02-28
Abstract: PURPOSE:To minimize an error brought forth in a measuring system, in measurement of a settling time, for instance. CONSTITUTION:A known stepped wave a(t) is inputted to a measuring system 2, so as to obtain x(t), and frequency axis area functions A(jomega) and X(jomega) of them are determined. Then, the transfer characteristic G(jomega)=X(jomega)/A(jomega) of the measuring system 2 is determined preliminarily from these functions. An unknown waveform is inputted to the measuring system 2 from an object 1 to be tested, so as to obtain an output waveform y(t), and Y(jomega) is determined. This function Y(jomega) is divided by the aforesaid transfer characteristic G(jomega) and further it is multiplied by a transfer function G'(jomega) having a low-frequency- pass characteristic. Thereby Z(jomega)={Y(jomega)/G(jomega)}.G'(jomega) is determined. Since the measuring system 2 shows the low-frequency-pass characteristic generally, G(jomega)' cancels the effect (the effect of an error in a high-frequency area, in particular) of the transfer characteristic G(jomega) of the measuring system and a waveform z(t) being free from noise is obtained.
