Title: Magnetic clutch device with brake
Inventor: ABE SHINOGU
IPC: H02K7/112
Filed: 1978-03-08
Abstract: PURPOSE: To facilitate adjustment of the clutch gap and disassembling of a magnetic clutch device by constituting the same such that one end of a driven shaft is supported by a clutch bracket having a gap adjusting screw provided thereon while the other end is coupled to a driving shaft so that the driven shaft may be axially movable together with the driving shaft.  
     CONSTITUTION: A gap adjusting screw 16 is provided on one end of a clutch shaft 3 in a clutch section 2. The clutch shaft 3 is coupled at the other end thereof to a motor shaft 18 by a bearing 5 so as to be movable in an axial direction. If the adjusting screw 16 is loosened, the urging forces of thrust springs 19a, 19b displace the motor shaft 18, a fly-wheel 12 and a clutch friction disc 11 towards the clutch to reduce the clutch gap to zero to thereby lighten the adjusting screw 16 whereby the zero position can be easily found. If the adjusting acrew 16 is tightened to the maximum deformation of the springs 19a, 19b, the maximum gap can be obtained thereby. If a bolt 23 is removed and then the adjusting screw 16 is tightened, superfluous thrust after the maximum gap is obtained acts as a disassembling force which permits the clutch device to be disassembled.

Abstract: PROBLEM TO BE SOLVED: To make an estimation unnecessary when welding parameters are set and reduce the number of decisions by interpreting the trial results of a specific welding step in the interactive mode with an operator through an interface and an input device, and deciding the value of a set of the parameters automatically in the setup mode. SOLUTION: The type of a material to be used for joining is decided, then a welding step displayed on an interface device 27 such as a display unit is selected and the selected welding step is entered to an input device such as a keyboard to supply this data to a control device 19. In addition, other sets of information relative to the welding step, for example, a welding area and a welding distance in the case of welding including compression joining are entered to the input device 29. Next, the type of a welding machine is entered to set the initial value of the welding parameters. Further, a quality evaluation is entered to the input device after welding the parts using the parameter initial value, and based on this evaluation, the modifications of the parameters are ranked in the increasing order of corrective effects and are executed.  Finally, the procedures are switched to the operation mode after repeating these modifications.

Title: Mos semiconductor storage device
Inventor: MATSUI YOSHINORI
IPC: G11C11/409
Filed: 1990-02-06
Abstract: PURPOSE:To prevent a current consumption from being increased due to a defective part by detecting an address of a normal memory cell array having a defective part with an output of an replaced address program circuit during the precharge period and stopping the delivery of a precharge control signal to a precharge circuit of the normal memory cell array corresponding to the detected replacement address so as to stop the precharge of a digit line. CONSTITUTION:A replacement address detection control circuit 7 is provided with plural logic circuits 71 and a Y decode circuit 2 generates a control signal PHIC turning off a transistor (TR) Q1 of a normal memory cell array of a memory cell array section 1 corresponding to a replacement address when a precharge control signal PHIp is an active level. That is, in the case of precharge when the precharge control signal PHIp is at a high level, the control signal PHIC goes to a low level and the TR Q1 of the normal memory cell array having a defective part is turned off, then digit lines DL1, inverse of DL1 of the memory cell array are not precharged. Thus, even when a word line WL is in short-circuit with a digit line, no current flows through the short-circuit point.

Title: Flat plate lens
Inventor: WADA HIROSHI
IPC: G02B3/00
Filed: 1990-02-07
Abstract: PURPOSE:To eliminate the need for polishing after filling a transparent material into recessed parts which form curved surfaces on bottom walls and to obtain uniform lens performance by forming these recessed parts on one surface side of a transparent glass substrate, filling the transparent resin material having the refractive index different from the refractive index of the substrate into the recessed parts and joining another transparent glass substrate to the substrate surface opened with the recessed parts. CONSTITUTION:The recessed parts 12 which form the curved surfaces on the bottom walls are formed on one surface side of the flat plate substrate 11 consisting of glass. The transparent resin material 13 having the refractive index larger than the refractive index of the substrate 11 is filled into the recessed parts 12. A resin layer 13A having some thickness is simultaneously applied and formed on the substrate surface and another transparent glass substrate 14 having a flat surface as a cover plate is joined to this surface. Since the transparent cover plate 14 is joined via the resin layer 13A stuck on the surface in this case, the flat surface of the cover plate 14 is utilizable as it is as a light incident/exit surface. The need for surface polishing is eliminated in this way. Since the resin packing thicknesses in the respective lens parts are uniformized by the pressing and joining of the cover plate 14, the lenses having the uniformized optical characteristics are obtd.

Abstract: PURPOSE:To make uniform the hardness of rail in its longitudinal direction by mounting partition plates on a cooling header to cool the specific range from the end part of rail and separating the space in between both surfaces of the cooling header and the rail head part in the rail longitudinal direction. CONSTITUTION:The header part of a hot rolled rail 11 is directly heat-treated by a cooling device 10 which is provided with cooling headers 12-14 and by which approximate all length of the rail head part is encircled with a cooling medium of air. In this method, among all cooling headers 12-14, one or more pieces of partition plates 15 are mounted respectively to the cooling headers 12-14 for cooling the range of approximate <=3m from the end part of rail. The space in between surfaces of the cooling header part and the rail head part is separated in the rail longitudinal direction. By this method, since the air blown from the cooling headers 12-14 can not be blown in the rail longitudinal direction, the rail end part is heat-treated in the same condition as the center part of rail 11 and the hardness of the rail head part is made uniform.
