IPC: G03D13/00
Filed: 1991-05-01
Abstract: PURPOSE:To integrate workpieces without giving them gauging and fogging by temporary holding sheet-like photosensitive material continuously carried and releasing its holding and dropping it utilizing gravity directly before integrating them in perpendicular direction continuously. CONSTITUTION:A workpiece holder 1 is of four plate-like structure. The structure is justifiable so long as it has a shape capable of holding a sheet-like workpiece. However, it is necessary to set the height level relatively lower than the workpiece carrying device in the previous process. A workpiece can be dropped without giving shock against the top of the workpiece 8 during the integration of workpieces by moving the whole of the workpiece holder 1 so that the head section of the holder 1 may be positioned to the X side more than a workpiece stopper 2. Therefore, the top section of the workpiece 8 which is being integrated can be prevented from damaging caused by the edge of the workpiece having been held.

Title: Bimetal-type valve
Inventor: KOMIYA YASUO
IPC: F16K31/06
Filed: 1978-10-27
Abstract: PURPOSE: To enable the operation of a valve independently of the ambient temperature, by providing two equal bimetal plates in parallel with each other so that the large expansion side of one bimetal plate faces the small expansion side of the other bimetal plate and by providing a spring for applying a force to the valve in a direction to close it.  
     CONSTITUTION: Equal bimetal plates 4, 5 are provided at an upper and a lower levels in parallel with each other in an enclosed casing 2 so that the large expansion side (a) of the bimetal plate 4 faces the small expansion side (b) of the other bimetal plate 5. When the bimetal plate 4 is heated by a heating wire 3, the plate curves convexly downward by a quantity corresponding to that of heat transferred to the plate and a gap (r) takes place between the plate 4 and rigid members 6. At that time, the bimetal plate 5 is moved up together with a valve 10 by the elastic force of a spring 9 until the gap (r) is eliminated. Therefore, the valve 10 is separated from a valve seat 12 by a lift (r). The curved quantities of both the bimetal plates are equal to each other even if the ambient temperature rises. Since the valve is actuated by a predetermined electric signal independently of the ambient temperature, the valve can be easily controlled.

Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a long life tool improving flank wearing resistance and chipping resistance without large worsening cutting resistance and finish surface roughness, by constituting a grain size by a diamond particle of prescribed dimension or less, and forming rake face roughness in a prescribed range. SOLUTION: In a sintered diamond cutting tool, to a 7 to 9μm diamond grain size, a flank wearing width and chipping width are decreased when the grain size is decreased, a tool life is extended, but when the grain size is further decreased, the chipping width is decreased, but the flank wearing width is increased. Accordingly, in a range extending a tool life by considering flank wear resistance and chipping resistance of the tool, the diamond grain size is limited to 6μm or less. When rake face roughness is made less than 1μmRmax. the flank wearing width is extremely increased, so as to limit a lower limit to 1μmRmax, in a 1 to 10μmRmax. In this range, cutting resistance and finish surface roughness are increased, but in a permissible range.
