Title: Photointerruptor
Inventor: ISHIZAKI JUNZO
IPC: H01L31/12
Filed: 1986-07-04
Abstract: PURPOSE:To realize a minituarized photointerruptor which can be manufactured easily at a low cost, by molding a lighttransmitting resin around light-emitting and light- receiving elements to provide a pair of a light-emitting section and a light-receiving section and folding a common lead so as to oppose the light-emitting surface to the light-receiving surface. CONSTITUTION:Using a lead frame in which a common lead 9 is formed so as to interconnect the earth sides of lead sections 6 and 7 adjacent to each other while orthogonally intersecting them an light-emitting element 1 is arranged at the tip end of the lead section 6 and a light-receiving element 2 is arranged at the tip end of the other lead section 7 both by die bonding. Further, upper electrodes of the light- emitting and lightreceiving elements 1 and 2 are electrically connected to tapeshaped leads 6b and 7b, respectively, by the wire bonding. Then, the elements 1 and 2 are molded seperately with a light transmitting resin 3 to provide a light-emitting section 11 and a light-receiving section 12 which are connected in parallel by the common lead 9. According to this method, since the lightemitting and light-receiving elements 1 and 2 are arranged on one and the same lead frame and they are molded with resin seperately and simultaneously, the number of components as well as the number of processes can be decreased and the productivity can be improved.

Title: Field effect transistor
Inventor: ANDO YUJI
IPC: H01L29/06
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To reduce feed back components by forming electrically connected source and drain electrodes on a channel layer so as to make Schottky contacts between an undoped semiconductor layer and gate electrodes. SOLUTION: Part of an epitaxial layer structure is etched off, until an undoped GaAs buffer layer 11 is exposed and etched off to form RTD mesas, until an n-type GaAs channel layer 12 of an element part is exposed. On this layer 12, source electrodes 5S and drain electrodes 5D are formed to make ohmic contacts. On an undoped GaAs Schottky layer 14 on the RTD mesas, a metal such as Au is deposited to form gate electrodes 6a for making Schottky contacts. This imparts RTD rectifiable performance, so that a negative voltage is applied between the gate and drain in the normal FET operation to make a high impedance, thus reducing feed back components.

IPC: B65G7/02
Filed: 1982-09-16
Abstract: PURPOSE:To prevent lubricant from running out and reduce a lubricant application work in conveying a heavy electric apparatus or the like by adopting a structure of heaping up a lead plate, conveyance plate, sliding plate with a lubricant distribution groove and an interference plate or the like on a conveyance road surface in order, and placing thereon a heavy cargo for conveyance. CONSTITUTION:A heavy cargo 11 is jacked up, while a lead plate 13 is laid on a conveyance road surface 12 and a conveyance plate 16 is laid thereon. Then a sliding plate 19 with a lubricant distribution groove is placed so as to form a sliding member layer 17 on the conveyance plate 16. Subsequently, an interference plate 22 is interposed between the sliding plate 19 and the heavy cargo 11, which is released from its jacked up state and lowered on said plate 22. In this condition, the heavy cargo 11 is pulled and conveyed by means of a wire 11b. Due to the abovementioned structure, lubricant filled in the lubricant distribution groove of the sliding plate 19 is gradually supplied during conveyance and its running out does not occur even in a long-distance conveyance. The lubricant supply work can thus be reduced.
