Title: Manufacture of semiconductor laser device
Inventor: WADA HIROSHI
IPC: H01S5/00
Filed: 1987-09-28
Abstract: PURPOSE:To reduce leakage current, by forming current constriction layers in a three layer structure of pnp layers through a selective growth process using the dielectric layer left on a reverse mesa section as a mask so that an n-type clad layer is prevented from contacting directly with the n-type contracting layer. CONSTITUTION:After a p-type clad layer 12, an active layer 13 and a first n-type clad layer 14 are in turn grown on a p-type substrate 11, this three layers are selectively etched in a reverse mesa structure using a dielectric layer 15 as a mask. Next, current constriction layers 16-18 of pnp layers are formed on both sides of the reverse mesa section on the substrate. At this time, since the n-type intermediate current contracting layer 17 is so grown as to be held between the upper and lower p-type current constriction layers 16, 18, on both sides of the reverse mesa section, the n-type clad layer 14 is effectively prevented from contacting directly with the n-type current contracting layer 17. Subsequently, the dielectric layer 15 as a mask is removed, a second n-type clad layer 19 is then formed over the first n-type clad layer 14 and the current constriction layers.

IPC: H02P29/00
Filed: 1986-10-09
Abstract: PURPOSE:To prevent current from being fluctuated at the time of switching, by a method wherein speed control bias and forced bias are added to a speed control section prior to change-over from current control to speed control, and wherein the forced bias is reduced at the same time as the control is changed over, and wherein a limit value is slowly increased. CONSTITUTION:When a motor 1 is controlled by means of current control only, then a contact d is ON, and a contact c is OFF, and the input of current command C to a current control section 3 is provided. When the control is changed over to speed control, then contacts X1-X3 are turned ON, and the output of speed control bias v2 is generated. Prior to the time point, a contact(a) is turned ON, and the output of forced bias v1 is kept generated. Then, by limit value signal L, output A=current command C is set. After that, when the contacts a, d are turned OFF and the contact c is turned ON to control speed, then the forced bias v1 is reduced, and the limit value L is slowly increased from the lower to the higher. As a result, current is slowly changed.

CONSTITUTION:A sealing member 6 is formed as a film by spraying an inexpensive metal material, which has excellent corrosion resistance, thermal conductivity and ductility, directly on the bearing surface 41 of a housing seat of a plug housing 4. At this time, in order to increase the bonding strength between the spraying metal and the bearing surface 41 of the housing seat, the bearing surface 41 of the seat is roughened by sand blasting or an annular groove is provided in a ring shape. The heat of the plug housing 4, which is received from burning gas, is transmitted to a cylinder head 9 through the sealing member 6. At this time, the bearing surface 41 of the plug housing and a sprayed surface 61 form a unitary body and the contact surface becomes large. Therefore heat transfer is performed excellently. Thus, the thermal load to the pressure detector can be alleviated.

Title: Electronic oven
Inventor: FURUTAKI YOSHIO
IPC: H05B6/66
Filed: 1983-12-23
Abstract: PURPOSE:To prolong the durability of a magnetron (filament) by reducing the filament voltage at the time of magnetron oscillation, and making the filament temperature at the time of preheating equal to the filament temperarture at the time of magnetron oscillation. CONSTITUTION:At the time of preheating filaments, an external source voltage is applied between the terminal A and the terminal C of a filament transformer 3, and a filament voltage Ef is set to a high value. When a high voltage applying connector 1 is actuated so as to oscillate the magnetron 5, a changeover contact 2 of the filament voltage Ef moves downward, and an external source voltage is applied between the terminal B and the terminal C of the filament transformer 3, the filament voltage Ef is set to a value lower than that at the time of preheating. Accordingly, the filament temperature Tf assumes the same value at the time of preheating as well as at the time of the oscillating operation. Even when the ON-OFF operation of a short period oscillation is frequently repeated, no thermal stress is applied to the filaments. As a result, the durability of the filaments of the magnetron can be greatly prolonged.

The plating underlying films of the unnecessary parts are removed by an etching method, such as ion beam etching method, to complete the coil. Thus, the thin-film magnetic head of high S/N provided with the coil of the higher winding ratio and the lower resistance is produced.

Abstract: PURPOSE:To shorten the tape producing time and also to facilitate the production of the tape by calculating automatically the tilt angle of a punched hole shape based on the center position data on the punched hole shape and the data on the tip position of the punched hole. CONSTITUTION:A punched hole center position 5a and then a punched hole shape tip position 5b are hit on a CRT screen 2, and the punched hole center position data are converted into a punching center positioning control command. At the same time, a plotting-only system is used and then locked so as to recognize a fact that the center position of the punched hole produced by the first hit is always set at zero degree. Thus the tilt angle of the punched hole shape is automatically calculated from the punched hole center position data and punched shape tip position data. This tilt angle is converted into a punching rotary positioning control command. That is, an angle is calculated from zero degree when two points are picked up from a graphic shown on the screen 2. This calculated angle is put into a program for automatic production of a tape.
