Title: Surface acoustic wave filter and transducer used for it
Inventor: TANAKA MITSUHIRO
IPC: H03H9/25
Filed: 1995-10-31
Abstract: PURPOSE: To allow the filter to satisfy a filter characteristic on request in the communication system in terms of insertion loss, frequency characteristic and T.T.E(triple transmit echo) level entirely. CONSTITUTION: A unidirectional transducer 2 as a transmitter transducer and a 2-way transducer 4 as a receiver side transducer are formed on a piezoelectric substrate 1. A signal to be filtered is given to terminals 10, 11 and the frequency characteristic of the signal obtained from terminals 12, 13 is a characteristic being the product between the characteristic of the transmitter side transducer and the characteristic of the receiver side transducer. Thus, the insertion loss is small, the frequency characteristic is excellent and the T.T.E level is sufficiently suppressed.

Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To provide an electronic circuit which can move a solenoid in response to a command signal by impressing an oscillating current upon the coil of the solenoid. SOLUTION: Signal dividers R8 and R9 generate an upper peak current signal value V-PU and a lower peak current signal value V-PL which is fixed at a certain rate of the signal value V-PU from a command signal and a current detecting resistor R2 generates a current detecting voltage VSENSE indicating the current flowing through a coil L1. First and second comparators 14 and 16 respectively compare the voltage VSENSE with the signal values V-PU and V-PL. In a set/reset flip flop circuit 18, a current driver 28 is made to impress a driving current upon the coil L1 as the function of the output signal of the circuit 18 by latching the driver 28 to 'ON' and 'OFF' so that the current flowing through the coil L1 can substantially have the value V-LU.

Title: Arithmetic retrial circuit
Inventor: ONO SHINGO
IPC: G06F11/14
Filed: 1987-11-10
Abstract: PURPOSE:To prevent deterioration in the system function due to the intermittent troubles by using an arithmetic retrial means and inhibiting the next arithmetic operation for retrial of the same arithmetic operation when an error is detected out of the arithmetic result of a computing element. CONSTITUTION:When a system is operated and the operands are set at operand registers 4 and 5, an arithmetic sequence control circuit 9 is started by a sequence start signal 10. At the same time, the value of a retrial frequency presetting register 1 is preset at a retrial counter 2. Then a computing element 7 performs an arithmetic operation with use of the values of both registers 4 and 5. When this arithmetic operation is through, the circuit 9 sends a signal 11 to an error detecting circuit 8 for check of the arithmetic result 12. When the circuit 8 detects an error and the value of the counter 2 is not equal to 0, a retrial control circuit 3 counts up the value of the counter 2 by 1 and sets the retrial frequency with replacement. The circuit 9 inhibits the next arithmetic instruction and performs the same arithmetic operation again via the element 7. Thus the deterioration of the system function is prevented.
