Title: Semiconductor device
Inventor: HORIE YOSHIHIRO
IPC: H01L23/50
Filed: 1986-10-22
Abstract: PURPOSE:To prevent the positioning deviation of an external lead and the occurrence of a defective bend, to improve the efficiency of a mounting operation and a bonding operation and to reduce a defect due to a short circuit by a method wherein, after the tip part of the external lead has been kept installed at the heat sinking tub and electrodes of a semiconductor device are connected by a metal thin wire, the underside of the heat sinking tub is exposed for resin-sealing. CONSTITUTION:A semiconductor device 1 is mounted on the surface of a heat sinking tub; an insulating material is formed on the surface of the heat sinking tub 2 except the area where the semiconductor device is mounted; the tip part of an external lead 5 is kept on the surface of the heat sinking tub 2 by means of the insulating material 3. After the external lead 5 and an electrode of the semiconductor device 1 have been connected by means of a metal thin wire 4, the underside of the heat sinking tub 2 is exposed, and sassembly is resin-sealed in such a way that the radiation of the heat generated by the power semiconductor device 1 is not disturbed. Because the size of the heat sinking tub can be made bigger than that of a conventional system by the length at the tip part of the external lead, this method has a good effect on the heat sinking.

Title: Method for forming cup-shaped article having ruggedness on bottom
Inventor: TSUDA OSAMU
IPC: B21J13/02
Filed: 1994-10-18
Abstract: PURPOSE: To form a cylindrical outer circumferential wall at a rim part symmetrically on an axis and to make its end edge the same height, in forming a cup-shaped article with ruggedness on its bottom by means of a backward extrusion method. CONSTITUTION: While the main body 2 of a punch 1 advances nearly of a half reduction stroke α of the entire reduction stroke S that is required for forming, the main body 2 of the punch and a die 10 holding a base material M are relatively made one revolution, and then the relative revolution is stopped, with reduction imparted to the last stroke position of the main body 2 of the punch, to complete the forming. As a result, mechanical working for making the end edge of a rim part the same height is dispensed with, and the number of processes of the next stroke is reduced, improving the yield of materials.

Title: Image forming device
Inventor: IWATA NAOTAKA
IPC: G03G15/08
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To maintain an image of high quality by always keeping the layer thickness of toner on a developer carrier constant, in accordance with the lapse of time and environmental conditions, in an image forming device using a one- component developer. SOLUTION: The image forming device is constituted so that the potential difference between a developing roller 2 and a lower supplying roller 4b can be arbitrarily set by a device for varying the potential difference. When the charge quantity of the toner is large in a low humidity environment and attracting force to the developing roller 2 is great as well, the potential difference between the roller 2 and the lower supplying roller 4b is set so as to form an electric field where the toner is hardly stuck to the roller 2. Further, when the charge quantity of the toner is small in a high humidity environment and the attracting force to the roller 2 is small as well, the potential difference between the roller 2 and the lower supplying roller 4b is set so as to form the electric field where the toner is easily stuck to the roller 2.

Title: Solar sensor
Inventor: AKAHA SATOSHI
IPC: G01C21/24
Filed: 1988-10-06
Abstract: PURPOSE:To enable highly-precise detection of a solar angle information by providing a correction circuit which gives a current limination to a solar angle signal so as to correct it in the direction reverse to the direction being tantheta with respect to a solar angle theta and thereby corrects an approximate error of theta tantheta. CONSTITUTION:When the sunbeams enter photoelectric elements 10a and 10b from a slit 11 at a solar angle theta, they generate output voltages A and B corresponding to a solar image 17, respectively, and output them to an adder 12 and a subtractor 13. A divider 14 conducts an operation of C=(A-B)/(A+B) and generates a solar angle signal C. The signal C, which has a characteristic of Dtantheta (D is a constant) in relation to the angle theta, is led to a correction circuit 15 to be subjected to a correction in the direction reverse to the direction being tantheta with respect to the angle theta, and thereby it is corrected to be proportional to the angle theta. Parameters required for adjustment for the circuit 15 are determined by an output gain of the divider 14, a value of a resistance R1 and a breakdown of Zener diodes CR1 and CR2. The limit of a range of detection of the solar angle is this breakdown voltage. The signal C thus corrected is outputted E through an output buffer 16.

Title: Solidifying composition for waste
Inventor: TAKEI AKIHIKO
IPC: B09B3/00
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To obtain a cement-base solidifying compsn. to be used to solidify a waste housed in a container and to decrease the weight of a waste body by incorporating a cement and a lightweight aggregate with a specified or lower water absorption as the main components and kneading them with water. SOLUTION: The compsn. contains a lightweight aggregate having <=1% water absorption. As for the lightweight aggregate with <=1% water absorption, hollow spherical fly ash is especially preferable when considering the strength and working property. Further, the lightweight aggregate with <=1% water absorption is used together with a normal aggregate. By mixing proper amts. of the lightweight aggregate having <=1 % water absorption and the normal aggregate for use, enough strength can be obtd. and the density can be controlled to an any value in about 1.6 to 2.2 g/cm<3> range. Also a lightweight product can be obtd. In the cement-base solidifying compsn. used to solidify a waste housed in a container, 50 to 80 wt.% of the cement component is replaced by a fine powder of a waste concrete.

IPC: H01L29/78
Filed: 1984-12-03
Abstract: PURPOSE:To prevent the change in dimension of a thin film transistor, by manufacturing the thin film transistor by a constitution, to which a self-alignment method can be applied. CONSTITUTION:A metal such as Al, Cr, Mo and the like on a glass substrate S. Patterning is performed and a gate electrode 1 is formed.

Title: Etching method
Inventor: UENO ATSUSHI
IPC: H01L21/302
Filed: 1986-10-24
Abstract: PURPOSE:To make it possible to etch a silicon semiconductor with high accuracy into the pattern of nearly the same size as the etching mask size by dry etching by subjecting the silicon semiconductor to a first dry etching having a selective property in vertical direction and then subjecting a part of that to a second dry etching in vertical and lateral directions. CONSTITUTION:A polysilicon film 14 is produced on oxide films 11' and 13'. The surface of this polysilicon film 14 is composed of planes a', b' and c'. A resist pattern 15 for gate is formed on the bottom plane c' selectively. Next, the polysilicon 14 is subjected to etching, for example, reactive sputter etching selectively. Because fluorine radicals can be made to enter vertically, the polysilicon 141 can be formed into the pattern having a nearly equal pattern width to that of a resist mask without an undercut. Next, such dry etching that fluorine radicals as an etching gas are made to enter in the equal direction, that is, downward and in lateral direction is performed to remove the polysilicon 142 left on the side planes by using the resist as a mask. In this case, as the etching advances in both longitudinal and lateral directions, the substrate is etched from the b'' planes easily, rapidly and steadily. Lastly, the resist pattern 15 is removed.
