Title: Semiconductor laser
Inventor: KOTAKI YUJI
IPC: H01S5/00
Filed: 1988-01-14
Abstract: PURPOSE:To increase the intensity at a resonance frequency fr further, increase the limit frequency and realize a high speed operation by a method wherein an active layer is divided into a plurality of sections along the lateral direction perpendicular to the direction of a resonator and the lateral width including divided sections of the active layer is selected to be smaller than the oscillation wavelength. CONSTITUTION:If an InGaAsP active layer 10 is divided into a plurality of layers, movement of carriers toward the center part is suppressed and the lateral direction movement of the carriers is not induced even if the carrier concentration of the center part is reduced. Therefore, the limitation against the output increase at a resonance frequency is relieved and the light intensity at the resonance frequency can be further increased. Although the carrier concentration shows a distribution which is low at the center part, as the distribution of the light intensity is determined by a waveguide mode, a status wherein the light intensity is high at the center like with the conventional constitution is maintained and the lateral diffusion of the carriers is avoided. Therefore, the responsiveness at a relaxation frequency is improved accordingly and the light intensity at the relaxation frequency is increased so that a -3dB band can be extended to the higher frequency accordingly.

IPC: H04M3/02
Filed: 1987-01-17
Abstract: PURPOSE:To reduce the circuit scale remarkably by connecting plural stages of unit circuits each consisting of a shift register and an OR gate circuit in cascade end providing a clock frequency divider applying an operating clock to be fed to each unit circuit while frequency-dividing the clock sequentially corresponding to the cascade connection of the unit circuits. CONSTITUTION:Shift registers 1A-1D have respectively a signal input terminal T1 and a clock input terminal T2 and consist of plural stages. OR gates 2A-2D, clock frequency dividers 3A-3C and an OR gate 4 are provided and the unit circuit consists of the shift register 1A and the OR gate 2A. Similarly, the unit circuit is constituted by shift registers 1B, 2B and OR gates 1D, 2D respectively and the unit circuits are connected in cascade. Since the clock of the pre-stage subject to frequency division is applied as the clock of the unit circuit of the next stage in this way, the time width of the output becomes larger from each unit circuit sequentially and the same operation as the multi-stage connection of the shift registers is executed equivalently.

Abstract: PURPOSE:To reduce optical loss improving the efficiency of incident light by a method wherein a part of light receiving element is located in an optical wave guide. CONSTITUTION:In case of forming a light receiving element, after forming an etching mask 11 on a top N type InP clad layer 4, a window is opened to form a V channel 12 reaching a clad layer 4, an optical wave guide 3, a buffer layer 2 and a substrate 1.

Title: Controlling method of rectifier
Inventor: TAKAHARA HIDEAKI
IPC: H02M7/19
Filed: 1979-01-26
Abstract: PURPOSE: To control the occurence of higher harmonics by imparting a gate signal so that a current which flows through each thyristor arm composing a single phase thyristor bridge in a by-pass state may flow alternatively at a frequency of 1/n times the AC source frequency.  
     CONSTITUTION: After dividing a synchronizing signal from the wave-form shaping circuit 10 to a signal for bridge which allows the current to by-pass and one not to by-pass, a gate signal to the thyristors TH21∼TH24 converts to the 1/3 frequency at the 1/3 frequency circuit 24 when the by-pass current flows through the thyristor bridge and is supplied to a phase shift circuit 13, 14 through a charge over switch 25, while a gate signal to the thyristor TH11∼TH14 is phase-shifted at the same frequency as it is. In this case, the length of the gate signal becomes three times the conventional system and decreases the generation of harmful higher harmonics.

Abstract: PURPOSE:To rewind a magnetic tape securely by the constant extent which corresponds to a tape speed by rewinding the magnetic tape by a prescribed extent on the basis of a temporary stop signal, by counting a control signal, and by determining the rerecording position of the tape by the count value. CONSTITUTION:A temporary stop signal puts a capstan reversing signal generating circuit 9 and a reverse driving circuit 10 in operation through an AND circuit 8, and a capstan motor 11 starts reversing to rewind a tape. A control signal is reproduced by a control head 15 and counted by a counter circuit 20 through a waveform shaping circuit 19 and when the counter circuit 20 goes up to N, a signal is outputted. The signal stops the magnetic tape through a pinch roller ON-OFF circuit 22 and a pinch roller driving circuit 23, and the counter circuit 20 is cleared by a reset signal generating circuit 24; and the reversing signal generating circuit 9 is turned off by the output of the circuit 22 to drive the motor 11 normally. Consequently, the magnetic tape is rewound securely by the constant extent which corresponds to a tape speed.

Filed: 1986-01-18
Abstract: PURPOSE:To improve the availability of a controller to be controlled by detecting a specific component in a pulse signal and outputting a reset signal when the component is not within a specific range. CONSTITUTION:When a computer M22 goes beyond control and the execution of a program becomes abnormal, a cutoff means M24 is driven as long as the 1st specific component of the pulse signal from the computer M22 is not within the specific range, thereby stopping the controller to be controlled M21 from being controlled by the computer M22. An abnormality resetting part M26, on the other hand, outputs the reset signal to the computer M22 when the 2nd specific component in the pulse signal from the computer M22 is not within the specific range, so the computer M22 is initialized and starts processes from the beginning.

Filed: 1978-01-27
Abstract: PURPOSE: To control the liquid pressure of two different system brakes with a single controller by normally anti-skid-controlling one system brake and opposing this controlled liquid pressure against the other system brake as the pilot pressure.  
     CONSTITUTION: The control valve 400 communicates to the liquid pressure circuit between the actuator 100 and the wheel brake 13a and on the other hand to that between the master cylinder 11 and the wheel brake 13b, respectively. When the wheel detects the skid state and gives signals during brake actuation, the air changeover valve 200 responds to these signals and performs its changeover. Consequently, the piston 433 moves right and the ball valve 420 moves to the cut-off position due to master pressure. Simultaneously, the piston 140 moves due to differential pressure and the cut-off valve 110 moves to the cut-off position.
