IPC: B26F1/02
Filed: 1994-11-18
Abstract: PURPOSE: To provide an air press that is capable of super highspeed shearing and applicable also to the shearing of a hard-to-work material. CONSTITUTION: The device is provided with a first chamber 12 and a second chamber 13 on both sides of a piston 11; and a workpiece is worked by alternately introducing compressed air to both chambers and thereby reciprocating a piston rod 14.

Title: Method of determining coupling constant of distributed feedback laser
Inventor: KINOSHITA JUNICHI
IPC: H01S5/12
Filed: 1986-12-27
Abstract: PURPOSE:To draw a normalization coupling constant (kappaL) more correctly and easily, by measuring ratios of spectrum intensities of main mode and additional mode (P1/P0) lower than an oscillation threshold value while changing bias current sequentially from zero to the oscillation threshold value, and determining the coupling constant from dependency of the measured spectrum intensity ratios on the bias current. CONSTITUTION:When P1/P0 is plotted as a factor of bias gain alphabias/alphath by using kappaL as a parameter, changing modes of P1/P0 are dependent on kappaL. Accordingly, kappaL can be determined correctly from such general tendency. Scanning current lower than the threshold value of a GaInAsP/InP distributed feedback laser, a threshold value gain alpha is calculated from the current in view of a waveguide loss outside of an active layer alphaac and a waveguide loss in the active layer alphaex in a range from a stage a P1/P0 is started to be observed up to the threshold value, and it is plotted and fitted. The result is shown by circles in the graph, from which kappaL can be determined to be a little more than 1.0.

Title: Optical disk substrate
Inventor: FUKAMACHI YUICHI
IPC: G11B7/2537
Filed: 1987-12-08
Abstract: PURPOSE:To enable instantaneous curing and to shorten the time for polymn. by providing a substrate consisting of an epoxy resin contg. sulfonium salt as an initiator for curing. CONSTITUTION:The epoxy resin monomer added with triphenyl sulfonium is applied on a stamper 2 and a flat glass plate 3 is placed on this resin. UV rays 4 are then projected thereon from above through the flat glass plate 3. The epoxy resin 1 is successively stripped from the stamper 2 and the flat glass plate 3 and is heated for 10-60min at 80-150 deg.C. The grooves of the stamper 2 are exactly transferred and the influence by shrinkage on curing is not admitted in this case. Namely, the deformation of the grooves by the shrinkage on curing is eliminated and the resin is cured by light in about several seconds by using the epoxy resin which contains the sulfonium salt as the initiator and is cured by light and heat as the substrate. The parting of the molding from the stamper is thereby expedited and the complete curing by heat is attained.

Title: Semiconductor device and manufacture thereof
Inventor: KOTSURU HIDEAKI
IPC: H01L23/29
Filed: 1989-11-29
Abstract: PURPOSE:To prevent the surface and other parts of a semiconductor chip from being damaged even if fillers of large diameter are used by a method wherein the fillers larger than a certain value in diameter are contained only in the peripheral part of a molding resin.

Title: Image transmitter
Inventor: HARASAKI KOICHI
IPC: H04N5/073
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To generate a clock signal synchronously with an input video signal by providing the output of a video signal to be selected next and a dummy signal having a large phase difference to a video processing circuit and a synchronization circuit and providing the output of the video signal to be switched. SOLUTION: A changeover device 21 uses a switching control signal (c) from a controller 8 to select video signals from cameras 11 -1n or a dummy signal whose phase is delayed by 0.5H at a dummy signal generator 20. Thus, the dummy signal based on the video signal is given to a video processing circuit 4 just before the video signals from the cameras 11 -1n are given to a video processing circuit 4 and a clock generator 6. Since the phase difference between the video signal and the dummy signal is 0.5H at maximum, when the video signals are received from the cameras 11 -1n , a clock signal generated by a clock generator 6 is locked with the synchronizing signal of the video signal.

Title: Air-fuel ratio control device of engine
Inventor: SAWAMOTO KUNIAKI
IPC: F02D41/14
Filed: 1988-12-09
Abstract: PURPOSE:To enhance the responsivity in following-up after air-fuel-ratio feedback correction factor by sensing the change in a specific driving parameter, and by correcting the integral constant of the air-fuel-ratio feedback correction in response to this change. CONSTITUTION:A calculating means 11 calculates the feedback correction amount alpha from the deviation of the actual air fuel ratio given by a sensor 4 from the command air-fuel-ratio value measured by a measuring means 5. Each time a means 6 judges that the large/small relation of the two values of air fuel ratio has inverted, the process parameter after inversion is measured by a means 7, and a means 9 compares this with the judging reference set previously by a means 8, and if the result from judgement is small, a means 10 sets a small integral constant, if middle a large integral constant, and if large, again small integral constant. A sensor 13 senses change in a specific driving parameter, for example, varying speed of the throttle valve opening, and if small the means 4 corrects the integral constant to a smaller, and if large to a larger. Thus following-up after the feedback correction amount alpha can be given properly.
