Title: Surface acoustic wave multimode filter
Inventor: NAKAZAWA YUUZOU
IPC: H03H3/08
Filed: 1981-07-14
Abstract: PURPOSE:To form a BPF which has high Q and high stability in a high frequency band, by acoustically coupling surface acoustic wave resonators, which have the same resonance frequency, on the same substrate. CONSTITUTION:On a substrate 11, numbers of couples of interdigital transducer electrodes 12 and 13 of surface acoustic wave resonators which have the same resonance frequency are arranged adjacently at right angles to the propagation direction of surface waves. When both kinds of electrodes are coupled together acoustically for resonance, two oscillation modes, or a symmetric mode and an asymmetric mode are generated at right angles to said propagation direction. When a BPF is formed by utilizing resonance frequencies of those two oscillation modes, the difference in resonance frequency is reduced to the half width of the passing band of the BPF. Thus, the BPF having high Q and high stability in a high frequency band is formed.

Title: Production of metallic knob
Inventor: FUKAZAWA KINEHARU
IPC: B21D53/00
Filed: 1983-06-20
Abstract: PURPOSE:To enable mass production and to obtain products having consistency in the stage of cutting a side-walled and long-sized blank material and producing metallic knobs for an acoustic device by providing a step to the side wall of the blank material and cutting the end part of the side wall left in the stage of slitting the blank material at the slightly larger width after working of knobs. CONSTITUTION:A step 3 is formed along the root of the side wall 2 of a blank material 1. A slit 4 is formed at every size of a desired knob to the material 1. The slit 4 is formed in the state of leaving the end part 5 of the side wall on the step side without including the step 3. The material 1 is then subjected to knob fabrication such as hairline working, alumite finishing, finishing of the slit surface or the like over the entire part and thereafter the end part 5 is cut slightly larger than the width of the slit 4. One metallic knob is completed by such cutting. Since the end part 5 is cut slightly larger than the width of the slit 4, burrs are formed on the inside without projecting to the slit 4.

IPC: H02K11/00
Filed: 1988-05-09
Abstract: PURPOSE:To surely detect a step out condition by selecting an opening part for its width and a detecting element for its arranging position in an encoder. CONSTITUTION:An encoder 80 provides an opening part 84, and its width La is selected so as to be wider than at least a width Lb of an oscillating frequency generated in the time of step out. A detecting element 85, detecting a rotor condition of the encoder 80, is arranged in almost the central part of the opening part 84 in a direction of rotation of the encoder. By the constitution thus obtained, even when a motor is in vibration generating the step out, the detecting element 85 is prevented from being dislocated from an opening end part of the opening part 84. Consequently, a detecting output in the step out time is obtained equal to when the motor is stopped rotating. As the result, a condition of the step out can be surely detected in a control part.
