Title: Manufacture of single wavelength laser
Inventor: SAKAKIBARA YASUSHI
IPC: H01S5/00
Filed: 1989-08-29
Abstract: PURPOSE:To reduce the waveguide loss and to enable a low threshold value and an operation of high efficiency by a method wherein periodic grooves are formed on a semiconductor substrate and a semi-insulating layer whose thickness changes periodically is laid on said grooves in order to form a channel which effects current injection into an active layer periodically by impurity diffusion from the substrate. CONSTITUTION:Periodic grooves 42 are formed on a substrate 1 by using a conductor film 2 as a mask and an InP semi-insulating layer 22 is grown selectively in the grooves 42 by using a dielectric film 21 as a mask. Next, the dielectric film 21 is removed and a thin InP semi-insulating layer 32, an InGaAsP active layer 3, an N-type InP clad layer 4 and an N-type InGaAsP contact layer 5 are crystal-grown in order. At this time, by a heat treatment at the time of crystal growth or after the crystal growth, impurities in the P-group InP substrate 1 are diffused in the InP semi-insulating layers 22 and 23 and a part of the thin InP semi-insulating layer 32 formed by the second crystal growth is converted into P-type. Thus, a channel 6 for effecting periodic injection of carriers into the InGaAsP active layer 3 is formed. In the InGaAsP active layer 3, a current is injected through the channel 6 so that a periodic carrier density distribution is formed.

Filed: 1988-09-06
Abstract: PURPOSE:To operate a reading-out at a high speed by supplying a larger current to a precharge circuit until the potential of a selected data line amounts to a desired level. CONSTITUTION:A precharge circuit PC in the same circuit constitution as an initial stage amplifying circuit PA is provided, and the precharge circuit PC includes an amplifying MOSFETQ 21, whose gate is linked to a common data line CD, an inverted amplifying circuit consisting of a load MOSFETQ 22, and a MOSFETQ 25, which is in a source follower mode and supplys a precharge current by receiving an output signal. In such a case, the cut-off potential of the MOSFET 25 in the source follower mode is set lower than that of the initial stage amplifying circuit PA for the potential of the common data line CD. Consequently, the precharge operation up to a constant potential is promptly executed by the precharge circuit PC. Thus, high-speed reading is attained while the desired signal quantity is being secured.

Inventor: AKAO NORIHIKO
IPC: B25J13/08
Filed: 1994-09-19
Abstract: PURPOSE: To detect the magnitude of a force acting on an arm to be accurately detected even if a cable to be connected to a force sensor is handled in any way. CONSTITUTION: A cable supporting part 16 is provided with independent of a driven part 24 provided with a force sensor 60, and it is slid by a slide mechanism (for example, a ball screw 28, nuts 46, 54) by interlocking them with each other. A cable 10 is connected to the force sensor 60 while being supported (fixed) by the cable supporting part 16.

Abstract: PURPOSE:To prevent an electronic component from turning in a top tape peeling space and from vibrating at a window for take-out electronic components by constructing the equipment in such a mechanism having a plate section below a tape so that it may energize the tape upward and downward. CONSTITUTION:A tape presser 4 is provided with a space 14 to peel a top tape 7 and a window 15 for taking out an electronic component 2. A section from the space 14 to peel the top tape 7 to the window 15 has a smooth face having almost no carriage resistance of a tape 1, being energized downward by the tape press 4. This equipment is constituted of a plate 5 which has a width longer than a longer side (width) of the electronic component 2 and which abuts on the tape 1, a spring 16 which holds the plate 5 upward but has load so that it may not prevent the transfer of the tape 1 by pressing the plate 5 too hard and which keeps the height of the abutment face between the tape press 4 and the tape 1 constant, and a tape transfer face 3 having such a shape to set the plate 5 free downward. Due to this structure, the rotation of electronic components such as exfoliation of the top tape is prevented.

Title: Method and device for rolling metallic sheet
Inventor: TAZOE NOBUHIRO
IPC: B21B13/06
Filed: 1984-10-24
Abstract: PURPOSE:To improve the quality and strength of a sheet-end part as well as to improve the accuracy of sheet width, etc. by subjecting the width-end surface to rolling reduction while restricting the inner side position from the width-end face of a metallic sheet stock from its upper and lower sides, to increase the rolling reduction in width direction. CONSTITUTION:A gap between clamping roll-bodies 3 is previously adjusted, by adjusting a gap between vertical rolls 11 in accordance with the width of a sheet stock 9, and supplying a pressurized oil to cylinder chambers 2 in accordance with the thickness of stock 9. When the stock 9 is fed, its front end enters in between the rolls 3, 3 in a state of being bitten by them, and its width-end surfaces are forced out to the downstream side with the rotations of bodies 1 of vertical rolls 11 while reducing he width of stock 9. At that time, a rolling down force by the bodies 1 acts mainly to form dog bones 9a without heavily acting on the central part of stock 9, and the buckling of stock 9 is not produced even when the stock 9 is subjected to large rolling reduction in its width direction because the stock is restricted in its width direction by the rolls 3. Accordingly, a wide thin stock is easily subjected to rolling reduction, and the strength of sheet-end parts is improved by subjecting the once bulged parts to rolling reduction in their thickness direction at the outlet side.
