Title: Memory control method
Inventor: ISHIWATARI OTONARI
IPC: G06F13/16
Filed: 1984-09-12
Abstract: PURPOSE:To control the timing to access a memory device by providing a ROM activated by a control signal which accesses the memory device and by using output data of the ROM. CONSTITUTION:If, for example, required conditions are that RAI3-0 are '0' and SRVIN, RFRQ are '0', and when there is no request for access to a ROM31, an output of the ROM31 are not activated since RAS, CAS strobe signals remain '1'. Then, if an access request signal SRVIN is inputted as an address from CPU, RAI3-0 remain at '0000' but an RAS strobe signal is activated after 50ns and goes to '0'. At this moment, output signals RA3-0 which specify the next address of the ROM31 go to '0001' and become next address information. As a result, a CAS strobe signal is activated and goes to '0', and consequently RA3-0 output '0010'.

Filed: 1989-07-24
Abstract: PURPOSE:To prevent a printed board from being broken and soldered parts from being peeled due to a shock by a method wherein a protrusion is formed on a part of an operating board in front of a transformer and projected up to the top of the transformer. CONSTITUTION:A transformer 8 is soldered on the front part of a printed board 7. A protrusion 9 is provided behind an operating board 2 and projected up to the top of transformer 8. The protrusion 9 is designed to support the heavy transformer 8 when an equipment rolls over or falls down and gets a shock on the top. The protrusion is formed into a shape of trough 10 on the transformer 8 side so as to provide it with a strength, and in addition, two or more ribs 12 are projected from a front raised piece 11 and attached to a front edge 13 of a top board 4 to support it. Therefore, the top board 4 is prevented from being distorted as it is supported by the ribs 12, and when water permeates into the equipment through the butt joint between the top board 4 and the operating board 2, the water is trapped in the trough 10 so that the power source transformer 8 is prevented from being splashed with the water.

Title: Semiconductor device and its manufacture
Inventor: TAKEMURA YASUHIKO
IPC: H01L29/78
Filed: 1994-07-21
Abstract: PURPOSE:To prevent the electrons trapped in an interlayer insulation film from affecting an N-type active layer, etc., by so forming an insulation film to trap positive charges that it is contacted with the N-type active layer or the N-type active layer having a low impurity concentration. CONSTITUTION:A source region 110 and a drain region 111 are formed respectively by the injection of phosphorus of the impurity to give N-type to the regions 110, 111. In this process, lightly doped regions 112, 116 are formed concurrently with the formations of the regions 110, 111. Also, in this process, offset- gain regions 113, 115 whereinto no impurity ions are implanted are formed respectively. Thereafter, by the applying of a heat treatment to the regions 110, 111, 112, 116 whereinto the impurity ions are implanted, these regions are activated. Subsequently, a silicon nitride film 100 is formed thereon by a plasma CVD method. By the formation of this silicon nitride film 100, negative charges can be induced on the surfaces of both the source/drain regions 110, 111 and the lightly doped regions 112, 116. Thereby, it is made possible that the electrons trapped in a silicon oxide film 117 do not affect the regions 110, 111, 112, 116, etc.

IPC: G03G15/09
Filed: 1987-07-30
Abstract: PURPOSE:To obtain practically sufficient intensity without requiring any high- level machining accuracy and to improve productivity greatly by welding a sleeve and a flange together. CONSTITUTION:The flange 1 and sleeve 2 are fixed by a jig and then one end part 4a of the shaft 4 of a magnet roll 3 is stored through oil containing metal 1b in the bearing 1a of the flange 1. Similarly, the other end part 4a' is inserted into a bearing 1a' and the sleeve 2 and flange 1' are fixed by a jig. Then YAG laser light is projected on four positions of join parts between the sleeve 2 and flanges 1 and 1' to perform spot welding. Consequently, welding strength of >=100kg-cm is obtained, so the high machining accuracy nor projection treatment for an adhesive is required unlike a conventional caulking or adhering method and the productivity is improved greatly.

Abstract: PURPOSE:To improve the protection of respective fibers and to improve the parallel state of the fibers by applying a secondary coat on a primary coat while the primary coat is held half cured. CONSTITUTION:Plural pieces (for example, 4 pieces) of the coated optical fibers (f) let off from bobbins 2 of a supply stand 1 are fed into a primary coating tank 4 while the interfiber spacings are narrowed by edging rollers 3.

Title: Production of liquid crystal display element
Inventor: NAKAI NORIYUKI
IPC: G02F1/1335
Filed: 1993-07-06
Abstract: PURPOSE:To suppress the thermal shrinkage of glass substrates by a heating stage by subjecting the glass substrates to a heat treatment at the highest temp. in production stages before the first heating stage. CONSTITUTION:The glass substrates (blue plates, 86X10<-7>/ deg.C coefft. of thermal expansion) sized 450X550X1.1mm are subjected to the heat treatment at the highest temp. (300 deg.C for forming oriented films) in the production stages. As a temp. profile, the substrates are heated up to 300 deg.C in three hours, are kept at 300 deg.C for one hour and are cooled down to room temp. in six hours. The color filter substrates are then produced by the similar production stages as for liquid crystal elements by using the glass substrates subjected to the heat treatment at 300 deg.C. The glass substrates subjected to the heat treatment at 300 deg.C which is highest in the production stages hardly thermally shrink even after the formation of ITO films and do not generate the deviation in patterning of the ITO electrodes and light shielding layers. The misalignment between the light shielding layers and counter auxiliary electrodes at the time of sticking is similarly prevented as well.

Abstract: PURPOSE:To control the light quantity of a photodetecting part and at the same time to ensure the rain-proof performance by providing movably a masking plate between the opening part of a mask cover and the photodetecting part to control the quantity of light supplied to the photodetecting part and at the same time covering an entire circuit with a housing. CONSTITUTION:When a control knob 5 is moved to the edge part, a projection 9 is put into a slit 15 and therefore a masking plate 14 moves upward. Thus a photodetecting part 7 is totally opened. Then the projection 9 of the knob 5 is moved to a recess part 13 and positioned there. When the knob 5 is slid horizontally and set into the part 13, the plate 14 moves downward in steps to cover the part 7. Thus the quantity of light supplied to the part 7 is controlled again. Then the part 7 is totally covered when the knob 5 is moved horizontally, and the plate 14 is descended to the lower most position. Further, the rain-proof performance is ensured by covering the entire of the photodetector and a circuit part.

Filed: 1984-09-13
Abstract: PURPOSE:To accurately stop always a carriage stably at the prescribed position by providing attracting means for generating an attracting force with a permanent magnet at the predetermined position of the back surface of a conveying path. CONSTITUTION:Magnetic fluid 5 is magnetized by the influence of a magnetic field generated by a permanent magnet 4 provided at the leg 32 of a carriage 3, thereby always maintaining the carriage 3 in a levitated state. The carriage 3 can be moved along a conveying path 1 in the suitable direction by a drive force of a linear motor. When the carriage 3 approaches the vicinity of a destination C to be stopped, the exciter 63 of a plunger mechanism 6 is excited to lift a rod 62, thereby approaching an iron piece 61 to the lower surface of the path 1. Thus, an attracting force is generated by the electromagnetic operation with the magnet 4, thereby generating a stopping brake force at the carriage 3.
