Title: Semiconductor device
Inventor: ABE TAKEYUMI
IPC: H01L21/60
Filed: 1983-06-30
Abstract: PURPOSE:To prevent the shortcircuit of wirings and the flow of the wirings by shifting the center of a semiconductor chip by half pitch from the external lead terminal of the true center, and shifting a bonding pad disposed at one side of the chip in the shifting direction to the vicinity of the opposed sides. CONSTITUTION:The center of a semiconductor chip 7 is shifted to the position displaced by half of a pitch P between external lead terminals from the center line for connecting the external lead terminal 21 at the true center of an external lead terminal 2 to an external lead terminal 22. A bonding pad 101 is shifted from a region 91 of the shifting direction to the region 92 of the opposed side. Thus, the distance between the terminal 22 and the pad 102 and the distance between the terminal 21 and the pad 101 can be shortened. Accordingly, the wire for bonding can be shortened.

Title: Production method of replica and replica produced thereby
Inventor: TAKAISHI HIROSHI
IPC: B44F11/02
Filed: 1988-05-16
Abstract: PURPOSE:To produce a precise replica easily with low cost, by applying synthetic resin liquid having adhesion and forming a transparent film upon dry up onto the surface of a picture or a photograph printed on a paper then drying the paper and immersing the paper into water thereafter peeling off the rear sheet and producing a projecting/recessed pattern on a resin sheet. CONSTITUTION:Synthetic resin liquid such as acrylic polymer emulsion having adhesion and forming a transparent film upon dry up is applied uniformly onto the surface of a print. When dry up and application of synthetic resin liquid are repeated 3-4 times, the surface of the print is covered with transparent resin sheet. Then the sheet is immersed in the water for about 15min and washed off when the paper section is softened thus producing a transparent resin sheet having a clear image. Thereafter, it is dried up and the rear ink face of the sheet is glued onto a canvas and the resin liquid is applied again onto the surface of the sheet. A separatable patterning paper such as a silicon paper is pressed onto the upper face of the sheet before the sheet dries up. When the patterning paper is separated upon dry up of the sheet, a clear image appears through the pattern.

Title: Light control device
Inventor: HAMADA YOUSUKE
IPC: B60Q1/115
Filed: 1984-06-08
Abstract: PURPOSE:To secure proper frontward lighting as well as to make it possible to prevent a passing opposite car from dazzling, by detecting the physical quantity related to a relative angle being made by a car body and a road surface, while setting an optical axis of light to a proper angle to the road surface. CONSTITUTION:When a car comes to an upward slope, causing the center of gravity to be moved to the rear part and increasing a body angle gamma alone, and a road angle delta remains unchanged, a transistor of a road angle detecting sensor 10b continues to have an on-state, while a transistor 12 of a body angle detecting sensor 10a comes on but a transistor 11 comes off so that the input from the transistor 12 to a NOR gate 43 becomes a low level signal. On the other hand, since the input fed to the NOR gate 43 becomes a low level signal entirely, the output of the gate 43 turns to a high level signal and inputted into an OR gate 48 so that a transistor 71 comes on, whereby an electric current is fed to a filament f1 from a battery source 80, thus a lamp glows. Simultaneously with this, a filament f2 goes out. That is to say, when the body angle glows larger in the specified value than the road angle and an optical axis of light comes too much high, the filament is made to glow, compensating an optical axis angle.

Abstract: PURPOSE:To provide automatic direction conversion of a disc body by installing the temporary setting base of the disc body on the fixed frame side at the side part of a junction conveyer which can lift freely to a fixed frame and rotate around the center of a longitudinal shaft. CONSTITUTION:A junction conveyer 15 is raised with an operating device raised to be connected to the final end of a carrier conveyer 1, so that the conveyer 15 is driven by a driving device 16 to locate glass plate 3 carried on the conveyer 1 onto the conveyer 15. Next, the conveyer 15 is lowered with the operating device 13 lowered to support the glass plate on it over a section between the receiving pieces 22 of the temporary setting base 20. Then the conveyer 15 is rotated by 90 deg. around the center of the longitudinal shaft, and is displaced by 90 deg. to the glass plate 3 so that they may face each other. By this, the conveyer 15 is raised to lift up the glass plate 3 and connect the conveyer 15 to the final end of the carrier conveyer 2. It is thus possible to move the glass plate 3 on the conveyer 15 to the conveyer 2 and discharge it, with the glass plate 3 carried, returning its direction by 90 deg. with regard to the direction at the time of carrying of the conveyer 1.

Title: Production of continuously cast steel ingot
Inventor: NISHIKIORI KIYOAKI
IPC: B22D11/055
Filed: 1985-06-01
Abstract: PURPOSE:To obtain an ingot of which the outside circumference and inside part have the equivalent characteristics by using a water-cooled copper mold for the upper part and a mold consisting of a different material for the lower part in the stage of continuous casting. CONSTITUTION:The part of the length (h) from the top side of the mold 1 is constituted of the water-cooled copper mold 5. The molten metal M poured into the mold is quickly cooled in the part in contact with the mold 5 to form a chill layer 2. The chill layer 2 is grown until the depth (t) of the layer 2 in the position at the bottom end of the mold 5 attains <=50mm. The lower mold 7 of the material consisting of cast iron, ceramics, etc. having the heat conductivity smaller than the heat conductivity of the mold 5 is disposed as the mold in succession to the mold 5. The cooling rate of the ingot 3 past the mold 5 is thus decreased by the contact with the mold 7 and the growth of the layer 2 is suppressed. The continuously cast product having substantially the same quality at the outside circumference and in the inside is thus obtd.

Title: Semiconductor device
Inventor: SUZUKI KAZUMI
IPC: H01L29/747
Filed: 1987-05-15
Abstract: PURPOSE:To reduce a gate trigger current by isolating a base region at a second main electrode side into two regions, and isolating between the isolating region for isolating them and the base region having a second emitter region, the second main electrode by an insulating film. CONSTITUTION:First and second p-type second base regions 31, 32 isolated by n-type regions 1a, 1b are formed on the second main surface of an n-type semiconductor substrate 1. An n-type second emitter region 5 is formed in the region 31. Further, when a positive voltage is applied to a first main electrode 7, a negative voltage is applied to an electrode 9, and a negative potential is applied to a gate electrode 9 to the electrode 7, since the region 31 is not brought directly into contact with the electrode 9, holes are not directly absorbed to the electrode 9, but a junction between the regions 31 and 5 is forward biased. As a result, it is conducted only by implanting small amount of holes. When a positive voltage is applied to the electrode 8 with respect to the electrode 7, the junction between the regions 31 and 5 is directly forward biased, thereby reducing a gate trigger current.
