Title: Method of and circuit for driving piezo-electric audio converter by signal and circuit
Inventor: PEETAA KURAIN SHIYUMITSUTO
IPC: G01S15/10
Filed: 1981-03-13
Abstract: A piezoelectric ultrasonic transducer is triggered by a predeflection of the transducer in a first direction with a square-wave pulse or a saw-tooth pulse which has a rapidly dropping trailing edge to effect deflection in the opposite direction, with an overshoot. At the maximum point of overshoot, an alternating triggering voltage, preferably in the form of a pulse sequence, is applied to energize and maintain the transducer in resonance oscillation.

Filed: 1995-02-24
Abstract: PURPOSE: To increase the surge withstanding strength by forming intermediate electrodes DC-independent of counter electrodes at the end faces perpendicular to both main faces of a semiconductor cerami c board. CONSTITUTION: On both main faces 14a and 14b of a rectangular parallelepiped semiconductor ceramic board 11 are formed counter electrodes 12a and 12b and on the end faces 15a-15d perpendicular to the main faces 14a and 14b are formed four intermediate electrodes 13a-13d. To the electrodes 12a and 12b are connected lead wires 16. In such a chip type varistor, a surge current of charges flowing into one electrode 12a flows to the other electrode 12b and part thereof flows to the intermediate electrodes 13a,..., this reducing the surge current acting on the electrodes 12a and 12b. Thus, a chip type varistor having a high surge withstanding strength can be obtained at low cost, without greatly changing the size and shape of the element.

Title: Formation of dielectric coating
Inventor: TANI NORIAKI
IPC: H01L21/316
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To obtain stable dielectric coating at a high speed without the secular change of a target and without generating troubles caused by abnormal discharge and dielectric breakdown by executing sputter coating formation by using applied voltage in which negative d.c. voltage to be applied to the target changes to positive potentials at a certain pulse period. SOLUTION: In a d.c. sputtering method, the use of a low resistance (in which electric resistance measured in the sheet thickness direction under 1.5V applied voltage is regulated to <=10Ω.cm) ceramic material target is most excellent, but, in the case high power is to be applied for more increase the coating forming rate, the following troubles are caused. Therefore, applied voltage in which negative d.c. voltage changes to positive potentials at a certain pulse period is used, and coating formation is executed. In this way, charges accumulated on the target and at the inside are released, by which dielectric breakdown does not occur, and consequently, abnormal discharge, the cracking of the target and the generation of dust are not caused. The pulse time of the pulse period is preferably regulated to >=0.5μsec and the frequency to >=500Hz.

Filed: 1984-02-28
Abstract: PURPOSE:To shorten an apparent access time of a magnetic disc device by providing a disc cache controller with actual cache object areas and virtual cache object areas and switching automatically areas on a basis of frequencies in hit of accesses to both areas as required. CONSTITUTION:When the magnetic disc device is accessed by a higher device, extent tables 5-1 and 5-2 are retrieved; and when it is confirmed that data exists in an actual cache object area or a virtual cache object area, contents of a counter 6-1 (real) of 6-2 (artificial) which counts information indicating access of the area are incremented by +1. If data in the accessed area is stored in a cache memory (in case of a hit), contents of a counter 6-3 (real) or 6-4 (artificial) which counts the number of hits are incremented by +1. The number of accesses (the number of cache objects) and the number of hits are obtained, and, for example, the number of hits is divided by the number of cache objects to calculate a ratio of the number of hits, and an area having the highest ratio of the number of hits is switched to an actual cache object area, thereby shortening an apparent access time.
