Patent JP-H04158646-A (JP)
Title: Generating system for pn code
Inventor: SASE CHU
IPC: H04L9/22
Filed: 1990-10-23
Abstract: PURPOSE:To eliminate the need for an initializing logic circuit to set an initial value to a shift register and to simplify the circuit by providing a NOT circuit to set a PN code in the shift register to be a negative logic. CONSTITUTION:The system consists of a shift register 1, an exclusive OR 2 and a NOT circuit 3. A data in the shift register 1 is formed to be a negative logic, and since an output of the exclusive OR 2 is the same independently whether the input is negative logic or positive logic, the output of the exclusive OR 2 is extracted as a positive logic PN code. The NOT circuit 3 inverts an output of the exclusive OR 2 into a negative logic, which is inputted to a shift register 1. Moreover, in the initializing, the state of setting all bits to '1' by positive logic is attained by resetting the shift register 1 of negative logic. Thus, the initial value is set by reset only, the circuit is simplified and is made small.

Title: Data processor for embroidering-machine
Inventor: HAYAKAWA ATSUYA
IPC: D05B21/00
Filed: 1990-10-24
Abstract: PURPOSE:To avoid the occurrence of the situation in which a peculiar trapezoidal block, of which the side intersects with the side of another trapezoidal block, is not changed to a normal trapezoidal brock because the peculiar trapezoidal block is at the end of a row of the trapezoidal blocks, by including a means whereby the peculiar trapezoidal block positioned at the one end of a row of a plurality of the trapezoidal blocks is independently changed to the normal trapezoidal block. CONSTITUTION:Data indicating a plurality of trapezoidal blocks to be filled up with zigzag stitch embroidery are stored in a trapezoidal block data-storing means 1, and the trapezoidal black positioned at least at one end of a row of these trapezoidal blocks is a peculiar trapezoidal block, of which the side intersects with the side of another trapezoidal block. In this case, the peculiar trapezoidal block is independently changed to a normal trapezoidal block by a changing means 2. In the case in which the peculiar trapezoidal block held between two adjoining trapezoidal blocks is changed to a normal trapezoidal block, it is essential to one side established after its change holds two normal trapezoidal blocks in common, and the restriction in the time of its change is strong. On the other hand, when the peculiar trapezoidal block at the end of a row of the trapezoidal blocks is changed, the most end side belongs to one trapezoidal block only, and hence the restriction in the time of its change is weak.

Abstract: PURPOSE:To obtain a color former sheet for non-carbon pressure sensitive paper which can prevent the deterioration of a color forming performance under storage and an unwanted color contamination under storage during production processes by incorporating a phosphoric-esterified wheat starch of a specific particle diameter in the color former sheet coated with color former-containing microcapsules and a binder. CONSTITUTION:In a color former sheet, a phosphoric-esterified wheat starch having an average particle diameter of 10-60mum is incorporated, an alkali thickening-type styrene-butadiene copolymer emulsion is used as a binder, and a synthetic resin is used as a capsule film of a microcapsule. In this manner, an apparent effect can be obtained. The phosphoric-esterified wheat starch can be produced by a method in which an orthophosphoric liquid prepared to be pH5-6.5 is infiltrated into a wheat starch, predried, heated, and classified. The loading amount of the phosphoric-esterified wheat starch is 15-100 pts.wt. per 100 pts.wt. of the microcapsules. This color former has no or little possibility of unwanted color contamination and the reduction of a color forming performance under storage caused by light and nitrogen oxides.

Abstract: PURPOSE:To efficiently generate the intergranular fracture of a Fe-Ni-Cr alloy sample for analyzing an apparatus by repeating the adding and removing actions of hydrogen to a test material, and accelerating the intergranular brittleness on the surface of the material. CONSTITUTION:A sulfuric acid solution of one normal added with soda arsenite serving as a surface active agent is used as an electrolyte 1, and it is kept at the preset temperature by a mantle heater 2.

The potential change at this time is measured with a reference electrode 6 and the potentiostat 5 and recorded on a recorder 7. The intergranular fracture factor is increased as the hydrogen adding time is extended. After hydrogen is added, it is heated in the atmosphere to remove hydrogen, the adding/ removing actions of hydrogen are repeated, then the intergrunular fracture factor can be efficiently increased as compared with the case that hydrogen is only added.

Title: Vibration absorber
Inventor: IDE TAKANOBU
IPC: F16F13/14
Filed: 1989-11-02
Abstract: PURPOSE:To prevent excessive stress in an elastic member by restricting displacement of an outer cylinder through inserting a stopper into a gap of an elastic member so that the displacement does not exceed a certain limit. CONSTITUTION:An inner cylinder 12 is supported by a car frame. An outer cylinder 14 is shifted from an outer position toward an inner position by weight of an engine. By this movement, a distance L of a gap 22 increases. If a vibration absorber 10 receives violent vibration during running of a car, the outer cylinder 14 is going to move in the vertical direction. However, because an insert 94A of a stopper 94 is located in the gap 22, an inner surface of the outer cylinder 14 comes into contact with the insert 94A. Thus, amount of the vertical displacement is restricted. Consequently, the outer cylinder 14 can not move so much with respect to the inner cylinder 12. Thus, excessive stress in a rubber member 20 is prevented, and its durability is improved.

Title: Improved low side face rubber-made key pad
Inventor: PORII SUU YUNGERUSUUBATORAA
IPC: H01H13/702
Filed: 1989-11-01
Abstract: PURPOSE: To realize a highly tactile feedback function and a backlight function in a key pad by floating its rubber overlay from which keys are projected and forming a switching layer and a circuit layer interposed in it. CONSTITUTION: A key pad 100 has as the uppermost layer a silicon-rubber overlay 102 with a top from which a plurality of keys are projected and a flat bottom. The thickness of the highly tactile rubber overlay 102 is reduced owing to the provision of a driving strip 140 on embossed polyester dome 132. Since all layers 102 to 120 employed are transparent or translucent, light out of a diffuser plate is dispersed through the key pad 100. A conductor 136 on a flexible circuit layer 118 is arranged perpendicularly to a conductor 134 on a short-circuit layer 114, and the conductors 134 and 136 efficiently disperse light with their perpendicular and parallel, patterns. That arrangement produces a highly tactile feedback function and a backlight function in the key pad.
