Title: Method for calibrating torque sensor
Inventor: WASHIMI TAKASHI
IPC: G01L5/00
Filed: 1993-08-02
Abstract: PURPOSE:To calibrate the output value of a torque sensor with high accuracy by using the line connecting a torque-output characteristic point set through a first process and a torque-output characteristic point measured during a second process as the output characteristic of the torque sensor. CONSTITUTION:A torque sensor 1 is constituted of a magnetostriction film 3 which is formed on the outer periphery of the output shaft 2 of an internal combustion engine so as to detect the torque generated against the shaft 2 and a magnetic head 4 which detects the magnetizing state of the film 3. The sensor 1 is mounted on a vehicle while the sensor 1 is connected to the combustion engine. When the engine is stopped, no torque is applied to the shaft 2 and the shaft 2 is released from the torque T0 applied to the film 3 at the time of forming the film 3 and the film 3 is strained due to the restoring force of the shaft 2. The output V0 of the sensor 1 is measured in a state where the output torque of the combustion engine is '0' and a torque-output characteristic line connecting the point at which the torque is (T0, 0) and another point at which the output of the sensor 1 is (0, V0) is set. The output torque T of the combustion engine is detected by correlating the output of the sensor 1 during the operation of the combustion engine with the torque-output characteristic line.

Title: Surface acoustic wave branching filter
Inventor: HIKITA MITSUTAKA
IPC: H03H3/08
Filed: 1984-09-14
Abstract: PURPOSE:To reduce spurious components by constituting a reception filter of a branching filter and using an electroacoustic transducer being reactive to a frequency near the pass band to an antenna terminal of the filter. CONSTITUTION:A reception terminal RX and a transmission terminal TX of a branching filter are connected in parallel with an antenna terminal via reception filters R1, R2 and a transmission filter T respectively. A carrier inputted from the transmission terminal TX is filtered by the transmission filter T and transmitted from the antenna 1. The carrier received by an antenna 1 is filtered by the reception filters R1, R2 and outputted from the reception terminal RX. Since the input transducer of the reception filter R1 is constituted with a transducer using the interleave weighting method or the new phase weighting method, generation of a spurious wave due to mutual conversion is reduced.

Title: Magnetic recording and reproducing device
Inventor: TAKAHASHI KAZUYUKI
IPC: G11B15/43
Filed: 1994-08-15
Abstract: PURPOSE:To control the tape tension of a magnetic tape running in the take-up direction constant. CONSTITUTION:When the recording/reproducing operation is performed inversely to the tape 28 running in the take-up direction (direction of the arrow E), a tension band 122 is moved to the braking position by a changeover arm 124.
