Title: Frequency regulating method for piezoelectric resonator
Inventor: KITAJIMA TAKAMICHI
IPC: H03H3/04
Filed: 1990-04-06
Abstract: PURPOSE:To regulate surely frequency by forming a frequency regulation film with the charge control marking method to a piezoelectric resonator formed by forming an electrode to the surface of a piezoelectric substrate to regulate the frequency. CONSTITUTION:A piezoelectric resonator is formed by providing a vibration electrode 2 to a piezoelectric substrate and a terminal electrode 5 to the electrode 2 via a lead electrode 6. Then a frequency regulation film 3 is coated to the piezoelectric resonator by the charge control marking method to adjust the thickness of a vibration part 4, thereby regulating the frequency. Since the charge control (ink jet marking) marking method is a contactless system being not in contact with the piezoelectric resonator, no crack is caused in the piezoelectric substrate to improve the yield of the product. Thus, the frequency regulation of the piezoelectric resonator is implemented with high accuracy, and the occurrence of defective waveform in the characteristic of the resonator is suppressed.

Abstract: PURPOSE:To obtain the small-sized signal transmitting device of a rotating part which has high reliability and good transmission efficiency by arranging a light emitting element and plural optical fiber photodetection ends opposedly at the rotating part and a fixed part, and detecting emitted light by a photodetecting element. CONSTITUTION:Plural optical fibers 53a-53f are arranged in a stator-side housing 43 while facing the light emitting element 50 in the rotor-side housing 42A of the steering wheel of a motorcar.

Abstract: PURPOSE:To limit the lower limit value of the aperture opening in accordance with the zoom magnification ratio of zoom lens, by selecting either one of the outputs of the pickup element and the zoom magnification ratio detecting means via the voltage limiting circuit and then supplying the selected output to the automatic aperture control device. CONSTITUTION:The output voltage of voltage limiting circuit 15 is limited by output VZ of variable resistor 14 even in case output voltage V1 of preamplifier 4 increases so much so that the F value of aperture 2 is lowered less than characteristic curve B. Automatic aperture control device 10 prevents the F value of aperture 2 from lowering less than curve B. As a result, lower limit RO is secured for the depth of field, and thus a highly infocus shooting is possible although the zoom magnification ratio increases.

Title: Timing reproduction circuit
Inventor: OISHI YASUYUKI
IPC: H04L27/22
Filed: 1989-04-13
Abstract: PURPOSE:To reproduce a clock with less jitter only by means of a digital processing by folding the prescribed section of an eye pattern at a center value, taking it into a shift register and detecting a timing with a part where a track is vacant as the center of an eye. CONSTITUTION:An A/D converter 11 A/D-converters an input (eye pattern), and a decoder 12 develops it and sets a part where a waveform exists to be '1', and to be '0' except for said part. An OR circuit 13 takes the OR of every two bits which come to be a couple by setting the center level of the developing pattern as center, and synthesizes the total inputs/outputs of respective shift registers SR1-SRN of the shift register 14 in an OR circuit 15. A minimum value detection circuit 16 takes a part where '1' exist least for the center of the eye, gives the timing to a digital phase synchronous loop 17 and a demodulation clock is reproduced. Thus, the clock with less jitter can be reproduced only by the digital processing.

IPC: F28F1/40
Filed: 1990-04-09
Abstract: PURPOSE:To achieve a less heat resistance by arranging a spiral groove crossing a protrusion with a depth larger than that of a groove bottom part while a spiral protrusion is provided on the internal surface of a pipe corresponding to a spiral groove on the external surface of the pipe to eliminate stay and crystallization of a solution absorbed. CONSTITUTION:A pipe is made having a protrusion 1 and a groove 2 parallel with an axis of a heat-transfer pipe. A spiral groove 3 is provided having a specified pitch in a direction of the pipe axis. The spiral groove 3 crosses the protrusion 1 with a depth thereof larger than that of the bottom of the groove 2. A spiral protrusion 4 is provided on the internal surface of the pipe corresponding to the spiral groove 3 on the external surface of the pipe. A cooling water 6 flows through the heat-transfer pipe 5 and a solution 8 absorbed drops outside the pipe. With such an arrangement, the performance of the heat-transfer pipe can be improved in combination of the protrusion 1 outside the pipe and an effect of turbulence with an aid of the spiral protrusion 4 inside the pipe. When an equipment is stopped, the spiral groove 3 helps eliminate the retention and crystallization of the solution absorbed on the groove 2 thereby allowing remarkable decrease in heat resistance at the restarting thereof.
