Title: Piezoelectric vibrator
Inventor: KAWASAKI KOZO
IPC: H03H9/17
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal oscillation by providing the exciting electrodes opposite to each other on both sides of a piezoelectric substrate and also providing the pattern coils on the substrate which are connected in series to the exciting electrodes. SOLUTION: The exciting electrodes 2 and 3 and the terminal electrodes 4 and 5 are provided on the surface and back sides of a piezoelectric substrate 1 respectively. Then a zigzag pattern coil 6 is prepared between the electrodes 2 and 4 together with a zigzag pattern coil 7 prepared between the electrodes 3 and 5 respectively. The electrodes 2 and 3 are connected together via the pattern 6, and the electrodes 4 and 5 are connected together via the pattern 7. The coils 6 and 7 are placed opposite to each other against the electrodes 2 and 3. Thus a pattern coil is connected between the exciting and terminal electrodes of a piezoelectric vibrator, so that the impedance value of the vibrator is increased in proportion to its frequency. In this respect, the impedance of an oscillator is increased in the higher-order resonance frequency of the piezoelectric vibrator.  Thus the abnormal oscillation can be prevented.

Title: Printed wiring board
Inventor: ARAKI TOSHIO
IPC: H05K3/34
Filed: 1991-11-11
Abstract: PURPOSE:To form fillets in conic parts for performing the soldering step without fail by a method wherein one ends of through holes are formed into conic shape expanding diameter toward the counter part fitting surface while the lead ends are made even with the counter part fitting surface. CONSTITUTION:The diameter of both ends of holes 14 are expanded in conic shape. Accordingly, conic parts 20, 22 are formed respectively on the upper and lower ends of through holes 12 by plating layers 16 on the conic parts. When electronic parts with leads are mounted on the title printed wiring board 10 so far manufactured, the length of leads are previously made even with one another not to make the lower ends of the leads protrude from the counter part fitting surface. Next, e.g. when flow soldering step is performed, the counter part fitting surface is immersed in a melted down solder vessel. At this time, both of the inner surfaces of the through holes 12 and the leads are wetted with the melted down solder by the surface tention so that excellent fillets may be formed in both comic parts 22 and 20 thereby enabling favorable soldering step to be performed. Furthermore, the protrusion of solder from the counter part fitting surface can be almost avoided.

Abstract: PURPOSE:To obtain a superior base material for an optical fiber with high efficiency of deposition by introducing an annular flow of gas so that the diameter is gradually reduced toward the top of an oxyhydrogen burner, reducing the diameter of a flame and blowing this flame on a member subjected to deposition. CONSTITUTION:When a flame 300 contg. fine glass particles is jetted from an oxyhydrogen burner 100 such as a multinozzle burner, negative pressure is produced in the region A of an annular path 502 by the high ejection speed of the flame 300 and the open air is smoothly introduced from the rear side of a hood 500 and moved forward as an annular flow of air while gradually reducing the diameter. This annular flow regulates the flow of the flame 300 by its flowing and envelops flame 300 to reduce the diameter of the flame 300. This flame 300 having a reduced diameter is blown on the surface of a member 200 subjected to deposition.

Abstract: PURPOSE:To set an optional character in a short period of time by way of simple operation even in the case where retouching amount is much by providing a retouch signal making circuit to make a retouch signal by way of operation of a retouch switch. CONSTITUTION:The data printing device for camera in the title is provided with a retouch signal generation circuit to generate a retouch signal by operation of a retouch switch and is devised so that in the case when the retouch switch is switched on and off within a short period of time, retouching corresponding to the number of operation is carried out, in the case when the retouch switch is continuously pressed for more than specified period of time, continuous rapid traverse retouching is carried out and in the case of the midway, a rapid traverse speed is periodically changed and lowered to the speed which can be visually read out. Accordingly, it is possible to relieve a trouble of stopping rapid traverse occasionally and confirming how far rapid traverse is carried out and to increase the rapid traverse speed very fast. Consequently, it is possible to speedily and simply carry out retouching regardless of retouching amount by way of properly using both of continuous rapid retouching and single retouching per ON-OFF of a key as occasion demands.

Title: Microcomputer control circuit for high-frequency heating device
Inventor: YUASA FUMIO
IPC: H05B6/68
Filed: 1987-12-21
Abstract: PURPOSE:To interrupt the operation of a magnetron heater by making a comparison between the period of an all-time reset signal and its own reference time and judging that a microcomputer is running wildly, when the period of the reset signal is off the reference time. CONSTITUTION:A microcomputer 1 is running wildly and even if the period of a signal RES1, for example, is shorter than TR1, a signal Q is still at an 'H' level. And a signal REQ3 taken from NAND of the signals RES1 and Q turns to an 'L' level and transistors TRQ4 to TRQ5 is turned on, thereby turning forcibly the base of the transistor TRQ1 of an output drive circuit 6 to an 'L' level and turning off the transistor TRQ1. On the other hand, the transistors TRQ1 and TRQ2 of the circuit 6 have a function of turning on by themselves and off each other. This function is effectuated by a pulse signal sent when a start switch 7 is turned on at the start of cooking, and an 'H' level output signal P from the microcomputer 1. As a result, the transistor TRQ3 actuates the transistor TRQ3 for driving a relay 8 and this relay 8 is thereby turned on. The transistors TRQ1 and TRQ2, therefore, are turned off and the relay driving transistor TRQ3 driven with the transistor TRQ2 is turned off, thereby interrupting the operation of the relay 8 and a magnetron 9.
