Title: Thickness-shear piezoelectric vibrator
Inventor: KONNO TETSUO
IPC: H03H9/13
Filed: 1983-06-23
Abstract: PURPOSE:To eliminate the need for a stationary container and a holding member and almost remove external influence by converging thickness-shear oscillation energy to a piezoelectric area at a center part, and reducing the oscillation displacement of the surface of a piezoelectric element extremely. CONSTITUTION:Driving electrodes 4 and 5 are formed on surfaces 2a and 2b of a crystal piece 2 by vacuum-depositing metal or other methods. A lead-out electrode 4a from one driving electrode 4 is extended to the end part of the other main surface 2b. A crystal vibrator 1 is fixed directly to a substrate not shown in figure with an adhesive, etc., and the lead-out electrode 4a connects with a wiring pattern and the driving electrode 4. When an electric field is impressed to the driving electrodes 4 and 5, the crystal vibrator 1 enters thickness- shear oscillation. The displacement of the thickness-shear oscillation is maximum near interfaces between the piezoelectric area 2c and nonpiezoelectric areas 3a and 3a. Then, the oscillation displacement attenuates gradually in the nonpiezoelectric areas 3a and 3a and becomes extremely smaller on the surfaces 2a and 2b almost to zero.

Filed: 1987-05-12
Abstract: PURPOSE:To maintain the braking force while keeping the lateral force of a tire against the road surface by providing an orifice flow path and a check valve between displacement chambers. CONSTITUTION:A check valve constituted of a port 5i, a valve 5k, and a spring 5m is provided between displacement chambers 5p, 5g. When the pressure in the displacement chamber 5g is decompressed, the maximum pressure is enclosed in the displacement chamber 5p, the compressed air pushes back a piston 5c against the energizing force of a spring 5h, a magnet 5e is returned to the left, and a read switch 5q is turned off. Directly after a displacement chamber 2a starts to be decompressed, the pressure enclosed in the displacement chamber 5p escapes to the displacement chamber 5g side at a minor rate via an orifice flow path 5r, and the pressure in the displacement chamber 5p is slightly decompressed subsequently. The braking force can be thereby maintained high while the lateral force of a tire is kept high.

Title: Internal combustion engine
Inventor: MOTOYAMA TAKESHI
IPC: F02D45/00
Filed: 1991-04-19
Abstract: PURPOSE:To enhance the exhaust purifying performance by increasing the exhaust temperature at the time of engine starting and warming-up while, on the other hand, the merit of the stratified combustion engine is kept effective. CONSTITUTION:When, at the time of engine starting and warming-up, the temperature of a cooling water detected by a water temperature sensor 55 is below a prescribed value, since the fuel injection starting timing is advanced by fuel injection timing control means 61, the fuel is substantially uniformly distributed within a combustion chamber 23. On the other hand, since the amount of sucked air is decreased or increased in accordance with the increase or decrease in the number of idle revolutions and in addition the injecting amount of fuel is similarly decreased or increased by fuel injection amount control means 62, the fuel combustion is uniformly conducted as in an ordinary engine. Resultantly, the exhaust temperature becomes higher than in the case of a stratified combustion whereby the exhaust purifying performance of a catalyst at the time of engine starting and warming-up is enhanced. Excess of the cooling-water temperature over a prescribed value causes change-over from the uniform combustion to the stratified combustion. This makes effective the merit of the stratified combustion engine as it is.

Title: Angular velocity detector
Inventor: KOBASHI KAZUYOSHI
IPC: G01C19/56
Filed: 1990-04-27
Abstract: PURPOSE:To obtain the correct angular velocity by providing a second sound pressure detecting means for directly detecting the pressure of the sound generated from a vibrating plate, and comparing/correcting an output of a first sound pressure detecting means on the basis of the signal of the second sound pressure detecting means. CONSTITUTION:When a vibrating plate or diaphragm 2a of a speaker 2 is driven by an oscillator 8, there is brought about the pressure difference between the air chambers 5, 6 in a casing 1. As a result, the air begins to flow in an acoustic propagation path 7, generating the pressure difference within the acoustic propagation path 7. The pressure signal is detected by first sound pressure detecting means 3, 4, and sent to a signal processing circuit 9, where the signal is converted to a sensor output. The pressure of the sound generated from the diaphragm 2a is directly detected by a second sound pressure detecting means 12 and sent to the circuit 9 as a reference signal for correction. Based on the outputs from the detecting means 3, 4, 10, the circuit 9 detects the rotating angular velocity around a virtual shaft orthogonal to the propagation path 7. Since the pressure of the sound generated in front of the speaker 2 is detected directly by the detecting means 10 to be used as a reference signal for correction, the sensor outputs of the detecting means 3, 4 can be corrected, whereby the correct angular velocity can be detected.
