Title: Semiconductor rectifier element
Inventor: NAITOU KAZUYOSHI
IPC: H01L23/373
Filed: 1984-02-09
Abstract: PURPOSE:To allow a semiconductor rectifier element to be adapted for an automobile by composing a heat sink plate which mounts a semiconductor element of a copper clad iron, and securing the element to the copper layer of the surface layer, thereby enhancing a thermal impact resistance. CONSTITUTION:One surface of an Si chip 1 is secured with a solder layer 3a to the recess of the surface of a cup-shaped electrode plate 2 which is used also as a heat sink plate, and a lead 4 is connected through a solder layer 3b with the other surface. Silicone resin 5 is filled in an air gap on the plate 2 while projecting the upper end of the lead 4 as a semiconductor rectifier. In this structure, the plate 2 is coated with copper layers 11b on the front and back surfaces of an iron strip 11a of a core material, and the chip 1 is mounted on the layer 11b. here, the ratio of the copper to the iron of the clad material is important, and when the ratio of the iron is larger, thermal stress decreases, but the heat sink is deteriorated. On the contrary, when the ratio of the copper is larger, the properties are vice versa. However, the ratio of the iron is increased here by considering the utility of the rectifier.

Abstract: PURPOSE:To clean pond water gradually from the upper layers of a pond until the water is cleaned down to the pond bottom by surroundingly providing an inverted funnel-shaped flexible film-lie object in the bond, introducing the inflow water from rivers into a treatment chamber and pausing aeration after the aeration to allow sludge to settle, then transferring the supernatant water. CONSTITUTION:The inverted funnel-shaped flexible film-like object is surroundingly provided from the top at the center of the bond to the periphery of the pond bottom in cleaning of the pond water by the intermittent aeration. The inflow water from the up stream river R1 is introduced into the treatment chamber 2a to flex the film-like object 1 outward and to reduce the volume of an annular water storage part 2b. The aerator 7 is then driven. The aerator 7 is paused upon lapse of the prescribed time to allow the sludge to settle. A supernatant water transfer device 8 is operated to transfer the supernatant water into the annular water storage part 2b. The org. matter decomposition and denitrification are thus gradually progressed from the upper layer part of the pond and the sludge in the pond bottom is cleaned as well while sludge cleaning microorganisms are sufficiently cultured.

Title: Lead frame and manufacture of semiconductor device using same
Inventor: FUKUI ATSUSHI
IPC: H01L23/50
Filed: 1989-01-31
Abstract: PURPOSE:To improve the heat dissipation property of a semiconductor element mounting part and to contrive the improvement of the reliability of a semiconductor device by a method wherein the semiconductor element mounting part with a roughness formed on its peripheral edge according to the configuration of the points of inner leads is supported by a support bar in such a way that it comes more downward than a lead part formation plane and moreover, its outer edge comes on the side more outer than a region surrounded with the points of the inner leads. CONSTITUTION:A semiconductor element mounting part is supported by a support bar 9 formed integrally with lead parts 4 and 8 in such a way as to come more downward than a lead part formation plane. Accordingly, the mounting part is formed in such a way as to have a roughness according to the presence or absence of the inner leads 4 and its heat dissipation property is enhanced in such a way that the outer peripheral edge of this mounting part cores on the side more outer than a region surrounded with the points of the inner leads 4. Therefore, even if the mounting part is formed large, the mounting part and the leads 4 do not come into contact to each other and intersect three-dimensionally. Thereby, the heat dissipation area of the mounting part becomes wide and a highly reliable semiconductor device with a semiconductor element, which is never deteriorated due to heat, is obtained.

Abstract: PURPOSE:To simplify a switching operation and a circuit, and to enable a sound signal to be added even in high speed search time, by constituting a device so as to obtain a high speed search by raising the readout clock frequency of the sound signal. CONSTITUTION:When a mode is switched to a high speed mode, first of all, it is decided that a state is a reproduction state, and next, the readout cycle T of a memory (RAM) is switched to a cycle Ts/n. And when it is not a video reproduction time, in other words, when a head is located on a sound track, a head is sent to a track where a still picture corresponding to said sound information is recorded, then the still picture being reproduced, after a write on a memory (RAM) is completed, and simultaneously, the sound signal is read out from the memory (RAM) with the clock cycle of Ts/n. Therefore, the still picture and the sound signal having the speed of n-times are outputted. When the sound signal is terminated, the head is moved to the next sound track, and the still picture and the sound signal are outputted continuously in a similar sequence.
