IPC: H03H9/64
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To improve the transmission characteristic of the multi-stage ladder filter. SOLUTION: For example, 1-stage ladder circuits 51, 52, 53, 54 are connected in cascade to configure a 4-stage ladder filter. Parallel arm resonators 51p to 54p and series arm resonators 51s to 54s are respectively coupled in the 1-stage ladder circuits 51 to 54 and each of the 1-stage ladder circuits 51 to 54 forms a band filter. Elements 61, 62, 63 to suppress the mismatching losses between the filter circuits at each connecting position at each of the inter-stage of the 1-stage ladder circuits 51 to 54 are connected in parallel. The increase in the insertion loss at the low frequency of the pass band, attended by an increase in number of stages of the multi-stage ladder filter, is suppressed.

Title: Dielectric porcelain composition for high frequency
Inventor: SAITO JIRO
IPC: H01B3/12
Filed: 1993-06-29
Abstract: PURPOSE:To select a temperature coefficient from the minus direction to the plus direction by properly selecting the values of X, Y, Z in a composition expressed by BaxTiO2+Mn(Ymol%)+Ni(Zmol%). CONSTITUTION:A dielectric porcelain composition for high-frequency has a composition expressed by BaxTiO2+Mn(Ymol%)+Ni(Zmol%), where 0.1<=x<=0.5, and Y is contained by 0.3-0.5mol% and Z by 0.3-0.5mol%. The reason to set the range of (x) within 0.1<=x<=0.5, is that the temperature coefficient of resonance frequency becomes too large in the plus direction in the case of x<0.1, while the temperature coefficient becomes too large in the minus direction in the case of x>0.5. High-frequency characteristic is degraded outside of the range 0.3-0.5 for Y and Z. Sintering characteristic is degraded in the case of Y<0.3.

Title: Transducer driver
Inventor: OGAWA TADASHI
IPC: H02P25/06
Filed: 1982-09-13
Abstract: PURPOSE:To suppress the peak value of displacement with a resonance frequency and at the same time to secure the stability of a high band, by providing the characteristics of the voltage and current control type driving systems to a transducer at a low band and a high band respectively. CONSTITUTION:The servo signal is supplied to an operational amplifier OP1 via an input resistance R1. The output of the OP1 is turned into the driving signal of a transducer M via a resistance R8 and a booster circuit 5. The both- terminal voltage of a resistance R generated by a current is fed back to the input of the OP1 via a feedback impedance Zi consisting of a resistance R5 and a series capacitor C. At the same time, the output of the circuit 5 is fed back to the input of the OP1 via a feedback impedance Ze consisting of resistances R6 and R7 and a parallel capacitor C2. The impedances Zi and Ze are turned into the low band rise characteristics and the high band reduction characteristics respectively. Then the voltage and current control type driving systems are dominant for the low and high bands respectively. As a result, the peak value of displacement is suppressed with a resonance frequency and the stability is secured for a high band.

IPC: F04B53/16
Filed: 1978-12-26
Abstract: PURPOSE: To use a bell mouth for discharge and stripping, by making it equipped with a float and vertically expandable against a fixed pipe built in a tank.  
     CONSTITUTION: For discharging oil in a tank 1, a bellows 4 is contacted by means of a float 5 and a bell mouth 3 is also lifted to a certain level. As the oil discharge progresses and the liquid level gradually falls down to the upper surface of the float 5, and float begins to cease working and the bell mouth 3 also falls automatically to continue discharging oil until a stopper 6 comes in touch with the tank bottom. This means that the single bell mouth functions both for discharge and stripping. This construction is effective for reducing piping and weight of the tank 1.

Title: Output measuring device for stepping motor
Inventor: WATANABE ASAO
IPC: H02P8/38
Filed: 1992-05-27
Abstract: PURPOSE:To accurately measure output in state where a stepping motor and a load are coupled to each other, by measuring actual load torque via a comparison between a current feature under the application of an actual load and a preliminarily saved current feature, and multiplying the obtained torque by motor speed. CONSTITUTION:A reference load torque generator 3 is coupled to the output shaft of the stepping motor 1 of a master motor, and torque is changed. Then, coil current changes correspondingly and a current detecting section 10 detects, for example, coil current iB-. This current is amplified (step 11) and a feature extraction section 13 extracts a relationship between a drive current maximal value and load torque as torque versus current data via a terminal S1, and stores the data as a reference value (step 14). On the other hand, when this device is coupled to the motor 1 mounted on an actual machine mechanism 2 for measuring actual load, drive current detected under the same drive condition as for the master motor (step 10), is amplified (step 11). Then, another feature extraction section 15 extracts a maximal current value via a terminal S2 and stores the value (step 16). Also, a collation and judgement section 17 collates the maximal value stored in the step 16 with the torque versus current data stored in the step 14, and identifies and outputs actual load torque. This actual load torque is multiplied by motor speed for obtaining output.

Title: Cr oscillation circuit
Inventor: MORI KATSUAKI
IPC: H03B5/20
Filed: 1995-06-27
Abstract: PURPOSE: To acquire the desired oscillation frequency by providing a 2nd switching element group including plural switching elements which are controlled by the external signals between the other end of every resistive element and the input of an inverted element group. CONSTITUTION: The switches SW1 to SW4 are controlled by the control signal OP, so that the desired oscillation frequency is obtained. When a resistive element R1 is selected, both SW2 and SW4 connected to both ends of a resistive element R2 are turned off. Thus the element R2 is completely independent of a circuit. Then the total capacity value of the circuit is equal to the sum of the value of capacitors connected in parallel to the inverters Inv2 to Inv4 and the junction capacity Cj1 generated between the element R1 selected by the signal OP and a substrate. The junction capacity Cj2 that is generated between the substrate and the element R2 that is not selected by the signal OP never affects the operation of the circuit since the element R2 is completely independent of the circuit.
