Title: Piezoelectric resonator
Inventor: KAMIGAKI YASUYO
IPC: H03H9/17
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To obtain a resonator hardly causing malfunction due to breakdown or deformation, having a long life and a simple structure, and capable of being inexpensive and easily produced and dealing with a high frequency of GHz or higher by providing an oscillation wall, which projects from the surface of a substrate, on the substrate and forming an electrode an its side face. SOLUTION: A substrate 11 and an oscillation wall 12 projecting from the surface of the substrate 11 are provided, and a pair of electrodes 14 are provided on the side face of the oscillation wall 12. When a high frequency electric field is applied on the pair of electrodes 14, oscillation is generated in the perpendicular direction of the oscillation wall 12. That is, perpendicular longitudinal oscillation of oscillation in the direction parallel with the surface of the substrate 11 is used, and the oscillation energy is shut in the oscillation wall 12 to suppress the oscillation energy from leaking to the substrate 11. Consequently, a support film used in a conventional structure is not required to avoid a problem of cracks caused by the support film because oscillation is scarcely transmitted to the substrate 11.

Title: Rds radio receiver
Inventor: SASAKI MITSURU
IPC: H04H60/12
Filed: 1987-08-31
Abstract: PURPOSE:To continue receiving the same program without operation after tuning operation is once executed even when an FM broadcast is received during a moving on a vehicle by automatically receiving the program of the most satisfactory receiving condition out of the same program transmitted with different frequencies. CONSTITUTION:When a tuner 1 receives a program, a computer 6 gives a frequency setting signal a1 to a PLL (phase locked loop) 3 and an IF (intermediate frequency) detecting signal b1 of the receiving frequency is received from the tuner 1. At such a time, the computer 6 decides whether the receiving level is enough or not from the IF detecting signal b1 of the tuner 1 and when it decides the level is not enough, the scan of a tuner 2 is executed. This is realized by successively changing a frequency setting signal a2 given from the computer 6 to a PLL4. The computer 6 switches a control signal (d) so that an output c2 of the tuner 2 can be selected. Thus, even when the service area of the FM broadcast is changed during the moving on the vehicle, the same program can be continuously received without any manual operation.

Filed: 1983-11-18
Abstract: PURPOSE:To detect automatically a defect of static type memory by generating high-potential and low-potential inspection signals in a semiconductor memory device, one by one, and detecting a defect of a bit system with the inspection signals.

Title: Water stop device of sluice gate
Inventor: KIKUCHI AIKO
IPC: E02B7/20
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To minimize an extrusion pressure by forming a presser metal fitting on the atmospheric pressure side more thickly than a presser metal fitting on the hydraulic pressure side. SOLUTION: A presser metal fitting 6 on the atmospheric pressure side is formed more thickly than a presser metal fitting 5 on the hydraulic pressure side while a clearance S2 on the atmospheric pressure side is made smaller than a clearance S1 on the hydraulic pressure side. In the case when a sluice gate door 3 is closed, the sluice gate door 3 is slidingly closed while the head of water stop rubber 7 projected by the hydraulic pressure on a rear side is being pushed transversely. The head of the rubber in the early stage is separated from the sluice gate door 3 but when the sluice gate door 3 comes in contact with the head of the door 3 of the sluice gate later, a hydraulic pressure is loaded transversely on the head of the rubber, thereby producing the falling down of the head of the rubber on the atmospheric side.  The root of the head of the rubber is swollen to the atmospheric side by this falling down of the head. Since the presser metal fitting 6 on the atmospheric pressure side supports this swollen area, the amount of the falling down of the water stop rubber 7 is relieved. Therefore, the water stop rubber 7 when closing the door 3 of the sluice gate is not easily sandwiched with the door 3 of the sluice gate and the presser metal fitting, thereby extending the service life of the water stop rubber.
