Title: Active layer absorption type pulsation semiconductor laser diode and its manufacture
Inventor: FUJIWARA MASATOSHI
IPC: H01S5/00
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To make it possible for characteristics of pulse oscillation frequency to be set as a specified value independently of other laser oscillation characteristics, by oscillating a pule laser at a frequency corresponding to the difference between the energy band gap of a light absorption region and that of an oscillation region. SOLUTION: Firstly, a recess 50 is formed on the upper surface of a semiconductor substrate 1, in such a manner that slant parts 52a, 52b on both sides to a flat bottom part 51 have specified inclination. Secondly, a first clad layer 2 having a first conductivity type which is identical to that of the substrate 1, an active layer 3 having quantum well structure, and a second clad layer 4 of a second conductivity type which is different from that of the substrate 1 are formed on the semiconductor substrate 1. An insulating film 11 is formed on the second clad layer 4 above an oscillation region 23. By the etching using the film 11 as a mask, a ridge part 5 is formed as a unified body with the second clad layer 4. On both sides of the ridge part 5, a second conductivity type current block layer is formed and then a same conductivity type contact layer is formed.

Abstract: PURPOSE:To form a satisfactory resist mask and to improve the patterning accuracy of a metal layer such as an aluminum layer by forming a gentle protrusion at a corner which has an inner angle smaller than 180 degrees on the lower side of a stepped part. CONSTITUTION:For instance, a silicon dioxide layer 2 is formed on a silicon layer 1 and, a polycrystalline silicon wiring 3 whose surface is covered with an insulating film is formed on the layer 2 with a 90-degree bend. A protrusion D is formed in the polycrystalline silicon wiring 3 at the inner corner part. Then a metal layer 4 such as an aluminum layer is formed over the whole surface. At that time, a protrusion is formed in the metal layer 4 such as the aluminum layer similarly. Then a resist film 5 is formed and exposed with a mask 6 to make the unexposed part of the resist film 5 remain. The metal layer 4 is patterned with the unexposed resist film 5 as a mask. At that time, the protrusion formed at the corner of the metal layer 4 with an inner angle of 90 degrees divergingly reflects the exposing light by the action of a convex mirror. Thus the surrounding resist is not exposed to the reflected light to the extent of photoreaction.

Title: Rotating speed controller for diesel engine of engine test device
Inventor: OWADA AKIRA
IPC: F02B3/06
Filed: 1990-03-14
Abstract: PURPOSE:To secure the stability of rotating speed control with one changeover switch by providing a voltage divider which sets the correction of control constants of a two-speed and an all-speed governor engine, a divider which corrects the output signal of the voltage divider automatically, and a multiplier which multiplies the output signal of an amplifier by the signal from the changeover switch. CONSTITUTION:When an engine 1 is the two-speed governor engine (2SE), a switch 9 is connected to the side of a fixed level signal B1. In this case, a signal which is inputted to a throttle opening extent control part 6 is nearly equal to the output signal of the amplifier 3 and the control part 6 controls the rotating speed of the engine 1. Further, when the engine 1 is the all-speed governor engine (ASE), the switch 9 is switched to the side of the voltage divider 8 and a signal B2' is inputted to the multiplier 4 after the control constant due to the difference between the characteristics of the 2SE and ASE set by the voltage divider 8, and further a difference in the maximum torque of the ASE by a divider 7 and variation in torque inertia value are corrected automatically, so the rotating speed is stably controlled adaptively to the ASE characteristics.

Filed: 1987-03-20
Abstract: PURPOSE:To improve the effect of the charge and the discharge of a load capacity by a PNP transistor by making the amplitude of a signal impressed on the base of the PNP transistor for active pull-down larger than the amplitude of the signal impressed on the base of an NPN emitter follower transistor. CONSTITUTION:The transistors 11 and 12, a constant-current source 13 and resistances 14-17 constitutes a current switch and the resistance 17, the transistors 18 and 19 and the resistance 22 constitutes a level shift circuit. By making the amplitude of the signal inputted in the base of the PNP transistor 21 for the active pull-down larger than the amplitude of the signal inputted in the base of the NPN emitter follower transistor 20, the velocity that the current of the transistor decreases is accelerated when the output VOUT rises and the veloiity that the current increases is accelerated when the output VOUT breaks. Thus, the effect of the charge and discharge of the load capacity 23 by the PNP transistor can be raised and a switching velocity can be made higher.

Title: On-hook signal controlling system for radio transceiver
Inventor: OKADA KAZUYUKI
IPC: H04B1/40
Filed: 1980-05-16
Abstract: PURPOSE:To prevent an on-hook signal tone from being generated from a speaker, by transmitting the on-hook signal from a transmitter with the short break of a carrier, after a voice signal circuit of a receiver is interrupted. CONSTITUTION:When a receiver is in on-hook control, a transmitter interrupts a carrier momentarily before an on-hook signal C is transmitted, and the receiver detects this carrier short break with a squeltch of a receiver 1 and applies this detection signal to an AND circuit 10 together with the output signal of a flip-flop 7 stored with a transmission callout signal A already. The AND circuit 10 stores a flip-flop 11 to turn off a change-over switch 12 and interrupts a voice signal circuit to a power amplifier 3 from the receiver 1. Next, after the change-over switch 12 is off, the on-hook signal C transmitted from the transmitter is demodulated at the receiver 1 into a voice signal, which clears a sequence logical section 6 and flip- flops 7, 11 through an on-hook signal receiver 5 for the on-hook control of the receiver.
