Title: Semiconductor device
Inventor: MIZUTANI YOSHIHISA
IPC: H01L29/78
Filed: 1982-09-17
Abstract: PURPOSE:To prevent the derease of threshold voltages and reliability accompanied with the reduction of a channel length by a method wherein a drain region is composed of an impurity diffused layer of a double layer wherein the impurity concentration of the upper layer is lower than that of the lower layer. CONSTITUTION:After forming a field oxide film 102 on a substrate 101, an oxide film 103 is grown on an element region, and further a gate electrode 104 is formed. Next, ion implantation is performed by changing the kind of ions, and then activation is performed by heat treatment. Source and drain regions 105 and 106 formed in this manner consist of diffused layers respectively of double layer structure. At the time of ion implantation, it is so selected that the impurity concentration of the upper layer becomes lower than that of the lower layer. Finally, an interlayer insulation film 107 is deposited, and wirings 109 are formed. This method enables to prevent the decrease of threshold voltage due to the decrease of the channel length and the decrease of reliability due to impact ionization.

Filed: 1988-06-29
Abstract: PURPOSE:To prevent insulator from deteriorating due to an electrolytic corrosion at the time of application of voltage between wiring conductors on and in an insulating board by interposing nickel of substance having less transfer of components due to an electric field between copper of wiring conductor and the board. CONSTITUTION:An inner layer circuit conductor 2 is formed of metal copper foil on an insulating board 1. A metal nickel layer 3 is formed by nickel plating on the conductor 2. However, an insulating layer 4 made of an insulating base material must be provided between inner layer circuit conductor layers and between it and a board surface circuit conductor layer 5. Then, a hole to become a through hole is opened. A metal nickel plate 7 is formed by nickel plating on the inner wall 6 of the hole. Thus, an insulation deterioration can be effectively prevented not only on the board but between the conductor and the inner wall of the hole.

Title: Glare proof mirror
Inventor: SHIRAI YOSHIHIRO
IPC: G02F1/1335
Filed: 1984-08-01
Abstract: PURPOSE:To prevent the occurrence of an interference pattern and that of distortion of a reflected image by giving a micro irregularity to the inner surface of a base substrate of a transparent electrode substrate and then giving the high order flatness of the inner surface of a base substrate of a reflection-type electrode substrate. CONSTITUTION:A transparent electrode 2 and oriented film 3 are formed on a base substrate 1 of a transparent electrode substrate having a micro irrregularity on its inner surface, while on a base substrate 7 of a reflection-type electrode substrate having the high order flatness on its surface a reflecting electrode 6 such as an aluminum electrode and an oriented film 5 are formed. A guest/host type liquid crystal composition 4 is held between both substrates. Consequently the micro irregularity on the substrate 1 weakens the reflection intensity, and reduces or prevents the occurrence of an interference pattern, whereby the distortion of the reflected image will not occur due to the high order flatness of the substrate 7.

Title: Blow molding head
Inventor: IWAWAKI AKIRA
IPC: B29C48/475
Filed: 1978-12-28
Abstract: PURPOSE:To save the material at the time of material change by scraping thereof being attached  to the inside of the head and improve the surface condition through the first-in and first-out method by means of a material passage groove to the storage chamber provided on the inner  surface of the head-body or the wall surface of the plunger. CONSTITUTION:Material fed from a material feed inlet 10 is guided to vertical grooves along  both sides through a distribution passage 11 and reaches a storage chamber 9. As the material  accumulates, a plunger rises in such a manner that it is piled one upon another in sequence. The  vertical groove 8 comes exposed above a plate 2 but there is no material attached to the groove of  the exposed portion by the groove closing block 12. When the material accumulates up to the  given amount, an injection cylinder 19 is driven to extrude the material through a nozzle 15 to  form a parison 16. At this point, first-in and first-out action is made to ensure a molding of high quality. The vertical groove provided for the material passage allows the edge 7c to scrape off the  material thereby eliminating the retention of the material. The high speed passage of the material through the vertical groove 8 with a limited attaching area can also eliminates retention of the  material, thereby reducing the material for extruding away the proceeding material at the material change.

Abstract: PURPOSE:To control the rotation of a motor so that the shooting quantity of the metallic balls of every game machine, 'PACHINKO' is kept constant even if the machines of the same kind are used in common in the plural areas of the different frequencies of power supplies, by rectifying an AC power supply and then converting the resultant DC power to required oscillation outputs through an oscillation circuit, and by controlling the rotation of the motor with an inverter which uses the oscillation outputs. CONSTITUTION:An oscillation circuit 2 fed with a rectified DC power supply starts its oscillating operation, and outputs its oscillating outputs, which have mutually inverse phases respectively, from respective oscillation output parts OC1, OC2. By the oscillation output of high potential from the first oscillation output part OC1, a first driving transistor DTR1 is turned on, and at this time, by the oscillation output of low potential from the second oscillation output part OC2, a second driving transistor DTR2 is in OFF-state. Therefore, in an inverter circuit 3, a first and second control transistor CTR1 and CTR2 are turned on and a third and fourth control transistor CTR3 and CTR4 are turned off. As a result, a current ic1 flows through a motor 5, and thereby, the motor 5 is driven and rotated.
