Title: Switching power source
Inventor: ORIMOTO ATSUSHI
IPC: H02M3/28
Filed: 1991-09-13
Abstract: PURPOSE:To suppress a variation in a regulation range by providing a frequency varying circuit for varying a switching frequency of a switching circuit in response to a load current detected by a load current detector. CONSTITUTION:The switching power source comprises a load current detector 35 for detecting a load current IL flowing to a load circuit 24, and a frequency varying circuit 39 for varying a switching frequency of a switching circuit 4 in response to the current IL. With the configuration, if the current IL is relatively reduced, the switching frequency is raised, and even if the load becomes low, a regulation range is not varied. Since the circuit 4 has a direct saturable reactor 3 and the switching frequency is varied by the current supplied to its control winding 5, the frequency can be easily varied. Thus, the regulation range is not relatively varied for a variation in the load, etc.

Abstract: PURPOSE:To enable highly reliable solder bonding to be realized by a method wherein a solder material layer composed of a low melting point solder is interposed between a piezoelectric element onto which a metallic thin film is deposited by vapourization and a metallic plate to be laminated fast closely to each other, the laminate is placed fixedly in a vacuum chamber, and the metallic plate is bonded to the piezoelectric element by melting the solder material layer in an almost vacuum atmosphere. CONSTITUTION:A metallic vapour deposition film 3 of a piezoelectric element 1 is stuck fast to a solder layer 4 of a metallic vibration plate 2 to be laminated, which is placed fixedly on a preheater 10 in a vacuum chamber 11, and is pressurized from an upside with a metallic weight 12. Then, a vacuum pump 13 is operated, and the metallic vibration plate 2 is heated from its rear with a preheater 10 under a state wherein an inside of the vacuum chamber 11 forms a vacuum to bond a piezoelectaric element 1 to the metallic vibration plate 2 by melting the solder layer 4. At that time, temperature of the preheater 10 is precisely controlled so that temperature of the metallic vibration plate 2 is not less than a melting point of a low melting point solder composing the solder layer 4, and is not more than a Curie point of the piezoelectric element 1. Since heated under high vacuum, even though an oxidation film is not removed by flux, wettability of the solder 4 can be secured without oxidizing by heating the surface of the solder layer 4 becoming the bonded surface and the metallic vapour deposition film 3.

Title: Drilling presser plate and drilling method
Inventor: YOKOYAMA YASUTOMI
IPC: B32B27/18
Filed: 1990-09-10
Abstract: PURPOSE:To reduce generation of the frictional heat to be caused by the rotation of a drill to prolong a lifetime of a drill and improve the accuracy by using a laminated plate which consists of kraft paper or regenerated paper and unsaturated polyester resin as a presser plate to be used for drilling a wiring board. CONSTITUTION:Kraft paper and regenerated paper can be used as the base material, and a cost thereof is low, and when they are laminated to form a laminated plate, layers of the kraft paper and the resin are easy to be separated to prevent a phenomenon that the resin is penetrated into the paper to form the even structure. Hard resin layers can be therefore reduced to improve the drilling property of a drill 2. Especially, since phenol resin laminated plate to be used as a presser plate 3 at present is made of prepreg, which is obtained by impregnating the resin into the base material, molded under the high temperature and high pressure condition, the base material layer and the resin layers are evened, and since the resin is distributed evenly in the whole of the plate, resistance against the rotation of the drill becomes larger. In the case that the polyester resin is used, since the molding pressure at the time of molding the laminated plate is almost zero, it is extremely profitable. In the case that the lubricating agent is added, resistance against the rotation of the drill is more reduced.
