Title: Surface acoustic wave resonator and filter
Inventor: MIYAJIMA HAJIME
IPC: H03H9/25
Filed: 1988-06-23
Abstract: PURPOSE:To miniaturize a resonator and a filter by forming additional electrodes on the outside of electrode fingers of an IDT(interdigital electrode) to obtain a large Q value even for reduction of the number of reflectors. CONSTITUTION:An aluminium electrode film is formed on the surface of a piezoelectric substrate 10 consisting of crystal or the like. The thickness of the electrode film is set by the wavelength of a surface acoustic wave for the resonance frequency. An IDT 11 where two sets of electrode fingers cross is arranged in the center, and two reflectors 12 are arranged on both sides of the IDT 11. Each reflector 12 is arranged in the direction of propagation of the surface acoustic wave excited by the IDT 11, namely, in the direction orthogonal to the lengthwise direction of electrode fingers of the IDT 11. Additional electrodes 13 are formed in end parts of the IDT 11. These additional electrodes 13 are connected to the same bus bar so that their potentials are equal to potentials of adjacent electrode fingers. Consequently, additional electrodes 13 are not related to excitation of the surface acoustic wave. The surface acoustic wave excited by the IDT is multireflected by electrodes to generate a standing wave, and energy containment is caused. This principle is used to obtain the resonator.

IPC: B62K25/26
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a rear suspension of motorcycle free of any restriction on the rear arm arrangement, simplify and reduce the weight of the component parts, and assuring a wide degree of freedom for designing. SOLUTION: A rear suspension is composed of first rear arms 3 and second rear arms 4 in pairs up and down, a rear axle holding member 5, link mechanism 11, and spring damper unit 12, whereby the rear wheel 1 is suspended rotatably and capable of moving in the vertical direction. The first rear arms 3, second rear arms 4, and rear axle holding member 5 work as a link mechanism, and the rear wheel 1 moves in the vertical direction.

IPC: B31B50/83
Filed: 1989-06-19
Abstract: PURPOSE:To save the labor requiring for inspection by a structure wherein both a bringing-in means for recognizing the blanked state of a blanking form and for bringing the recognized blanked state in the device concerned and discriminating means for discriminating the blanking result of the blanking form whether it is good or bad are equipped. CONSTITUTION:After being blanked at a blanking section 3, blanking form 34 is carried between detecting photosensors 31-33 and floodlight projectors. When the light beam received by the photosensor 31 is shielded, the signal of the photosensor 31 is turned from high level to low level. Said change of signal is employed as a form tip signal. And the change of signal, which develops when the light beam received by the photosensor 33 is shielded, is employed as a form tail signal. On the basis of the two signals, an inspection gate signal is generated. On the other hand, signal sent from photosensor group 32 are inputted through an OR circuit into an AND circuit together with the inspection gate signal. When no unnecessary part is present, a high level signal is outputted from the AND circuit. At this time, pato light(R), buzzer signal and blanking machine stop signal are outputted from an inspecting section. Thus, the presence or absence of the unnecessary part can be automatically inspected and the saving of the labor requiring for inspection and the rationalization of inspection can be performed.
