Patent JP-H01292858-A (JP)
Title: Manufacture of semiconductor device
Inventor: TAKAGI HIDEO
IPC: H01L29/43
Filed: 1988-05-20
Abstract: PURPOSE:To acquire a contact of low resistance without raising impurity concentrations in a diffusion layer and polysilicon higher than required by forming a first low resistance material layer between a first high resistance material layer such as a diffusion layer of a substrate forming a contact and a second high resistance material layer. CONSTITUTION:A first low resistance material layer 12 is interposed between a first high resistance material layer 11 and a second high resistance material layer 13. Since the electric resistance of the first low resistance layer 12 is low, partical electric differential due to the position is eliminated, thus preventing generating of current crowding between contact windows. Moreover, by making it wider in the direction vertical to the current flow, electric resistance between the first low resistance material layer 12 and the first high resistance material layer 11 can be reduced. Therefore, current 16 flowing from a second low resistance material layer 14 through the second high resistance material layer 13, the first low resistance material layer 12 and the first high resistance material layer 11 becomes uniform and the contact resistance of the whole becomes low.

Inventor: MIYAHARA OSAMU
IPC: B29C65/00
Filed: 1982-07-15
Abstract: PURPOSE:To make the assembling work achievable without using any supplying means as well as to miniatrurize a device on the whole, by separating a molded assembly together with an assembled part as one body from the assembled part and then reassembling to said assembled part. CONSTITUTION:A chock 25 holding a molded assembly 8 by suction force is supported at the lower end of a slider 18 being supported by a head 22. A cradle 31 has the molded assembly 8 of an assembled part 1 positioned, a crosspiece 7 and projections 32 and 33 contacting with the undersurface of a molding part of a pin 2, and goes up to the extent that a top end of the projection touches the undersurface of the assembled part by operation of a cylinder 34. When the head 22 goes down, the chuck 25 holds the assembled part 8 by dint of attraction force. When the head 22 further goes down, a cutter blade cuts the crosspiece 7, then the head 22 goes up whereby a cylinder 16 operates, causing the slider 18 to travel, so that the assembled part 8 is moved to the upside of the pin 2, thus the head 22 is made to go down and assembled.

Title: Signal contention circuit
Inventor: UEMURA FUMIAKI
IPC: H03K17/00
Filed: 1995-05-22
Abstract: PURPOSE: To avoid a duplicated valid level of plural signals. CONSTITUTION: With signals DREQ, RESET received at an H level, a flip-flop 11 latches the H level of the signal DREQ synchronously with a clock signal CK. A flip-flop 12 latches the H level of the signal RESET synchronously with a clock signal CKN inverted to the clock signal CK. Succeedingly a flip-flop 13 latches the H level latched by the flip-flop 11 synchronously with the clock signal CKP to provide an output of the signal BREQ of the H level. In this case, a level of an inverted output terminal NQ of the flip-flop 13 is at L and a flip-flop 14 is reset. As a result, an output signal rst of the flip-flop 14 is guarded to be L.

Title: Ink duct for printer
Inventor: KUZUWATA MASAYUKI
IPC: B41F31/04
Filed: 1987-05-19
Abstract: PURPOSE:To allow smooth ink supply through prevention of a phenomenon of hang back in an ink duct by coating a surface contacting ink of ink duct blade with resin having a low energy level. CONSTITUTION:A phenomenon of hang back in an ink duct is prevented by decreasing adhesion between ink 3 and an ink duct blade 2 below that between the ink 3 and an ink duct roller 1. In order to achieve this, the ink duct blade 2 has a surface contacting ink of a metallic ink blade base 8 coated with resin 9 having a low surface energy level. The resin having a low surface energy level used should be one having a lower surface energy than ink used for printing. Generally the surface energy of ink is about 25-30dyne/cm, so that such resin should be selected from among those having 20dyne/cm or less of surface energy. The recommendable best suited resins used for the purpose are silicon and fluorine resins.

In this case, the label which consists of a laminate including an inorganic compound deposited layer, and the cloudiness of which is lower than the cloudiness of the container main body is used. Thus, by integrating the label with an excellent gas barrier property with the container main body, the gas barrier property is imparted to the container main body. Then, by the integration of the label with the container main body, a light is not dispersed between the label and the container main body, and the transparency of the whole body of the transparent container is improved.  In addition, the surface with which the label is integrated is covered by the label, and an unevenness on the surface of a metal die is prevented from being transferred, and for this reason, the surface of the container main body is not roughed, and the transparency does not decrease.

Title: Angle and displacement measuring instrument
Inventor: SAITO KENJI
IPC: G01C3/08
Filed: 1985-06-08
Abstract: PURPOSE:To eliminate influences of direction deviation of optical beams due to the variation of a light source by providing an optical element which inverts the passing position of one of two divided optical beams in the longitudinal direction. CONSTITUTION:One optical beam 8d divided by a beam splitter 2 passes an image rotator 3 and is irradiated to an object 6 to be examined together with the other optical beam 8c. If the beam 8a is varied by the variation of a light source 1 at this time, these optical beams are moved symmetrically with respect to an optical beam 8e and are moved symmetrically also on the light receiving face of a PSD (optical position detector) 9. Consequently, variation components of the light source in the division direction are eliminated. With respect to variation components of the light source in the direction orthogonal to said division direction, the fact that the passing position of the optical beam is inverted by the rotator 3 is used to invert the variation direction of an optical beam 8d', and this optical beam is shifted symmetrically to the optical beam which does not pass the rotator 3. Thus, horizontal and vertical variation components are compensated, and a certain output is obtained though the light source is varied in an optional direction.
