IPC: G02F1/11
Filed: 1986-04-23
Abstract: PURPOSE:To prevent the generation of heat at electrode surfaces and to elimi nate the deformation of an acoustooptic medium by consisting an elec tromechanical converter of two sheets of electrodes, piezo-electric element held between the electrodes and terminals to impress voltage and connecting the terminals to the electrodes along the longitudinal direction of the electrodes in the state of linear contact or face to face contact. CONSTITUTION:A metallic layer consisting of gold, etc., is formed on the surface of the acoustooptic medium 1 to form the common side electrode 2 and a piezo-electric element 3 such as lead titanate, zirconate, etc., is stuck onto the surface of the common side electrodes 2. A metallic layer 4 consisting of gold, etc., is formed on the surface of the acoustooptic medium 3 to form the hot side electrode 4. The hot side terminal 5 consisting of a lead wire bent to an L shape is connected to the surface of the hot side electrode 4 along the longitudinal direction of the electrode 4 by a conductive adhesive material 6 in the state of line contact. The resistance value from the junction points between the terminals and the electrodes to the ends of the electrode is thereby decreased to a substantially negligible level and the generation of heat is nearly thoroughly removed even if the transversely longer electrodes are used.

Title: Vacuum gauge
Inventor: HARADA KINJI
IPC: G01L9/00
Filed: 1989-04-12
Abstract: PURPOSE:To reduce the noises of an instrument and to improve the measurement accuracy by allowing a vibration beam to oscillate itself at its natural vibration frequency in a nonlinear vibration area. CONSTITUTION:The vibration beam 2 is made to vibrate itself at its natural vibration frequency in the nonlinear vibration area. Namely, the vibration beam 2 is in motion in a magnetic field, so a conductor crosses magnetic flux to generate an electromotive force. This electromotive force is amplified by an amplifier 3 and the vibration beam 2 oscillates. Then a counter 5 counts the natural vibration frequency of the vibration beam 2. Then a CPU 7 calculates the degree of vacuum from the natural vibration frequency of the vibration beam 2 from the output of the counter 5 and calibration data from a ROM 6. Then a display mechanism 8 displays the degree of vacuum according to the output of the CPU 7. Consequently, noises of the instrument are reduced to improve the accuracy.

IPC: B64C25/40
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the pressurized friction between the runway and the surface of a tire at the time of landing by disposing plural curved blades on the side of a wheel with a gradient to the axle side in the circumferential direction, and previously rotating the wheels of an aircraft before landing in the same direction as the wheel rotation at the time of landing and traveling by flight wind pressure. SOLUTION: Many curved blades 4 are disposed on the side of a tire 3 with the curved inner surface 4a inclined to the axle 5 side in the same direction at equal intervals concentrically and integrally. As a result, during the period from landing wheel releasing to grounding before landing, wheels 1 of an aircraft before landing are previously rotated in the same direction as the wheel rotation at the time of landing by flight wind pressure P through the curved blades 4. The outer peripheral rotating speed of the tire at the time of landing is kept substantially equal to the landing speed of the aircraft. Accordingly, the pressurized friction between the runway and the surface of the tire 3 can be reduced remarkably, so that the occurrence of an aircraft accident in landing caused by the friction of the tire can be prevented effectively.
