Title: Fine grinding stone for lens
Inventor: OGURA KOUZABUROU
IPC: B24D7/00
Filed: 1979-08-20
Abstract: PURPOSE: To enable a simple reforming of the grinding grains even if a spherical surface of the grains is deformed from a specified radius of curvature and further to improve an efficiency of grinding by a method wherein some diamond grinding grains are combined with some thermoplastic resins and some grooves are formed in the surface thereof.  
     CONSTITUTION: Diamond grinding grains 2 are mixed with the thermoplastic resin powder 3, a die is placed on the metal base 4 and they are heated altogether to soften the thermoplastic resin 3 to combine the grinding grains 2 with the resin 3 and at the same time the metal base 4 and the resin 3 are combined with each other Then, the grooves 5 are formed radially in the surface of the grinding grin layer composed of grinding grains 2 and the resins 3 starting from its centeral part. When the lens is ground with the diamond grinding stone 1 and worn out gradually to show a variation in an initial radius of curvature of the diamond grinding stone. The worn out wheel 1 is integrally formed again under an application of heat and pressure by using a correction die 7 and thereby a reforming of the diamnnd grinding stone to its initial shape or initial radius of curvature may be performed. Since some grooves 5 are provided in the surface of the grinding stone 1, some tips of grinding stone or glass material may be easily removed, resulting in improving an efficiency of the grinding operation.

Title: Method of manufacturing thermosetting resin pattern board and pattern board
Inventor: FUKUI RYOSUKE
IPC: B29C70/52
Filed: 1988-04-27
Abstract: PURPOSE:To simplify the processing and prevent the peeling, cracking and the like of a product by infiltrating thermosetting plastics resin to the fibre row being disordered, while keeping the reinforcement fibres advancing in the same direction, and heat molding this so as to represent the light and shade patterns on the surface thereof. CONSTITUTION:A plurality of glass fibres 1 are placed in parallel, and then introduced, in putting transversely directional waves thereon by means of a delivery roller 6, into a resin vessel 2, wherein they are adhered with unsaturated polyester 3 and further introduced into a heat molding machine 5 via a molding die 4, and the product 7 molded in this manner is molded in drawing at a constant speed by drawing devices 8, 8a, and further conveyed to a cutting process. The transverse waves give changes to the distance of patterns and the longitudinal waves give changes to the light and shade of patterns. Consequently, by controlling the fiber supplying condition during the molding period, the condition of pattern can be controlled. Since the pattern board is caused by the buried fibres, it may be constituted integrally and firmly, so that it is not likely to cause any peeling or cracking in use. And also, the production thereof is extremely simple and the change of patterns may be given diversely.

In this way, the pressure of oil fed in a delivery chamber 21a, 21b rises, and a reaction force, proportional to said pressure, causes the driven gear 3a, 3b to rotate around the main gear wheel 1 with the casing 2, fixed to its shaft 54a, 54b, made rotating in the same direction as a rotation of the main gear wheel 1. And if the oil  pressure in the above described delivery chamber rises higher, the rotation of the  driven gear 3a, 3b is impeded with the casing 2 and the main gear wheel 1 rotated  at the same rotational speed. At this time, a change of oil pressure due to a surge of  load is absorbed by a shock absorber 40.

Abstract: PURPOSE:To prevent generation of tapping noise improving visibility of a driver by providing constitution in such a way as positioning a connection part of an outer mast to a lift chain in the upper from the lowermost part of a chain wheel, when a carriage is placed in the lowermost lowering position. CONSTITUTION:When a carriage 11 is placed in the lowermost lowering position, a chain wheel 17 is mounted to a chain fixing bracket 16b so that a connection part of an outer mast 16 to the chain wheel 17 is positioned in the upper from the lowermost part 17a of the chain wheel 17. Consequently, the chain fixing bracket 16b is only protruded a little to the lower from an upper beam 16a, being particularly small in size and light in weight at a low cost as compared with the conventional large chain fixing bracket extending in a vertical direction of a vehicle, and also the length of a lift chain 12 is decreased. Accordingly, front visibility of a driver is widened. While by utilizing tension of the lift chain 12 acting on the chain wheel 17, generation of tapping noise can be prevented by interference of the outer mast 16 with an inner mast 15.

Title: Control circuit unit
Inventor: FURUTA MICHIHIRO
IPC: H02P7/292
Filed: 1986-05-07
Abstract: PURPOSE:To change a constant without requiring a special tool by examining presence absence of specified input from a contact point provided to connect an external equipment, and rewriting the content of a memory of a storage device by a man-machine unit when input is present. CONSTITUTION:When a CPU11 goes to a waiting state due to an error in constant setting, a specified signal is inputted from a vacant contact point, for instance a contact point 162, which is not connected to an external equipment. On receiving the signal, the CPU11 makes rewriting of constant from a constant setting operation panel 14, a man-machine unit, to an EPROM possible. Accordingly, when an operator inputs a new constant from the operation panel 14, a constant stored in the EPROM is rewritten, and control by a correct constant is executed. Thus, a constant can be changed without requiring a special tool.
