Patent JP-H0745733-A (JP)
Title: Semiconductor device
Inventor: WAKAO NOBUYUKI
IPC: H01L23/00
Filed: 1993-08-02
Abstract: PURPOSE:To prevent leads from being bent by a method wherein a lead cover is so displaced as to be separate from the body of a semiconductor device to cover the leads inside in a state other than a mounting state. CONSTITUTION:A lead cover 12 is positioned above the body part 11 of a semiconductor device by the elastic energizing force of a coil spring 23 before a semiconductor device is mounted. In this state that a semiconductor device is not mounted, all leads 16 are located inside the lead cover 12 and not exposed to the outside. Therefore, as the leads 16 are not exposed out of a semiconductor device, the leads 16 are prevented from being bent or damaged even if an external force is applied to them the semiconductor device is dropped.

Title: Liquid crystal display substrate
Inventor: HASHIMOTO YUICHI
IPC: H01L29/786
Filed: 1994-08-16
Abstract: PURPOSE: To suppress the generation of electrical shorting between gate wiring layers and drain wiring layers by constituting the gate wiring layers of chromium materials and forming extension parts along the extending direction of the drain wiring layers. CONSTITUTION: The gate wiring layers 1 extending in a direction (x) are formed on the main surface of a transparent substrate 6 consisting of glass. The material of these gate wiring layers 1 is composed of the chromium (Cr). The extension parts 5, 5' formed along both directions where the drain wiring layers 2 exist are formed in part of the regions of the gate wiring layers 1 where the gate wiring layers overlap on the drain wiring layers 2. Since the gate wiring layers 1 are formed of the chromium material, formation of pointed projecting parts known as hillocks or whiskers on the surfaces thereof does not arise and the generation of the electrical shorting is suppressed.  The extension distance of the stepped parts in the gate wiring layers 1 is increased and the probability of disconnection of the drain wiring layers 2 in the stepped parts is minimized by forming the extension parts 5, 5'.

Filed: 1986-08-18
Abstract: PURPOSE:To prevent the deterioration of image quality due to zigzag run of paper and creasing of an ink film, by pressing film peeling roller and a film pressing roller against a platen through a film roller holder. CONSTITUTION:A film peeling roller 3 and a film pressing roller 4 can be pressed against a platen 2 with the centers being adjusted, thereby a paper does not snake. When an ink film 11 and a transfer paper 10 are sandwiched with predetermined pressure between the film peeling roller 3 and the film pressing roller 4, carrying force of paper can be transmitted to the film thereby the ink film and the transfer paper can be carried with the same speed even at the non-image section so as to prevent creasing of the ink film. Furthermore, when it is pressed through a film roller holder 5, the sum of pressing forces will be constant thereby the total frictional force being applied from the paper to the film can be made constant irrespective of the tension of the film.

Title: Information processor
Inventor: YAMANASHI YOSHITSUGU
IPC: G06F13/00
Filed: 1988-08-03
Abstract: PURPOSE:To extremely shorten the memory access time by using the means to transmit the row and column address strobe signals respectively. CONSTITUTION:A memory controller 21 monitors the execution of a bus cycle via a mask (containing a CPU and a DMAC 2) and always outputs the row address strobe signals RAS to all DRAMs forming a memory 9 regardless of the presence or absence of a memory selector. At the same time, the controller 21 outputs a column address strobe signal CAS to a specific DRAM according to the decoding result of an address decoder 8 and based on the address outputted to the memory 9. Thus it is possible to give an access to a desired DRAM just with output of the signal CAS. As a result, the memory access time is extremely shortened.
