Title: Semiconductor laser device
Inventor: NAKAJIMA YASUO
IPC: H01S5/00
Filed: 1987-11-24
Abstract: PURPOSE:To enable modulation at high speed, and to change a transistor, etc., into an OEIC by integration in a monolithic manner by burying an active region composed of a first conduction band and a second conduction band into a trench deeply formed to a semi-insulating substrate and using one part of the substrate as the first conduction band. CONSTITUTION:A trench is shaped onto a semi-insulating substrate 1, and an n-InP clad layer 2, an InGaAsP active layer 3 and a p-InP clad layer 4 are buried into the trench, thus forming an active region. An n-type region 6 is shaped through a diffusion or ion implantation from the substrate side. When a bias is applied between a p electrode 7 and an N electrode 8, currents concentrate and flow through the active layer 3, and oscillation is enabled at approximately 20mA. Since the active layer 3 is approximately 2mum wide and approximately 0.1-0.15mum thick and is surrounded by an InP crystal having a low refractive index, a fixed waveguide is formed, and stable fundamental transverse mode operation is realized. Since the active region is buried into the substrate 1 and there is no P-N junction outside the active region, parasitic capacitance is reduced extremely. Accordingly, frequency characteristics are improved, and a modulation range is spread up to several GHz or several dozen GHz.

Title: Antiskid control device
Inventor: YANO TETSUNORI
IPC: B60T8/58
Filed: 1988-11-22
Abstract: PURPOSE:To improve braking performance by a method wherein by the feed of the same oil pressure to hydraulic braking means mounted to rear wheels on both sides right after the starting of antiskid control, running stability is ensured, and on and after a predetermined switching time, an oil pressure fed to the hydraulic braking means is controlled independently. CONSTITUTION:When the occurrence of the slip of a wheel is detected by processing circuits 4a and 4b, an antiskid control circuit 1 outputs a pressure reducing signal to switching valves 6a - 6d when the slip of a wheel is detected and an oil pressure in an oil cylinder is returned to a reservoir tank. When the slip is rendered ineffective, a boosting signal is outputted to the switching valves 6a - 6d, and a braking oil pressure is fed to the wheel cylinder. In this case, during a time between the starting of an antiskid control and a switching time when a car body speed is increased to a given value, for example, 80 - 100km/h, select low control is effected to feed the same oil pressure to the wheel cylinders of rear wheels. Meanwhile, on and after the switching time, independent control is executed, and an independently controlled oil pressure is fed to the wheel cylinders of the rear wheels.

Abstract: PURPOSE:To apply only one level adjustment for recording and reproduction of the system by providing a level adjustment device whose gain is inverted at recording and reproduction to an input and output section of a noise reduction and an FM modulator-demodulator. CONSTITUTION:An input signal to be recorded is inputted to an encoder 4 of noise reduction and a compressed signal enters a level adjustment device 6 and the adjust ment device 6 adjusts the input to the FM modulator to be a proper level and the input is recorded on a tape 1 via the modulator 2. A signal is demodulated via a demodulator 3 in the reproduction system and the level is adjusted by the adjustment device 6 and the result enters a decoder 5. In this case, the gain of the adjustment device 6 depends on a resistance R1 of an internal resistor 21 and a resistance R2 of an external adjustment resistor 22, the gain of the adjustment device 6 is expressed as GR=-R2/R1 and similarly the gain in the reproduction system is expressed as GP=-R1/R2. Thus, a signal passing through both the recording and reproduction systems is amplified by GR.GP=-R2/R1.-R1/R2=1 and the level in the recording and reproduction systems is kept constant. Thus, the level adjustment of the recording and reproduction systems is attained by the level adjustment at only one position in the system.

Title: Transfer device
Inventor: TAKATOU AKIHIRO
IPC: G03G15/00
Filed: 1988-11-25
Abstract: PURPOSE:To obtain good pictures even when transfer paper is deformed by setting the passage of guiding means on a transfer area side narrower and, at the same time, the carrying speed of a carrying means faster as compared with the moving speed of a toner image carrier. CONSTITUTION:The passage 30 of guide plates 24 and 25 on a transfer area A side is set narrower and, at the same time, the carrying speed of a resist roll 23 is set faster as compared with the moving speed of a belt-like photosensi tive body 1. Then the tail edge side of transfer paper 13 is forcibly waved along the carrying direction in the narrowed passage 30 of the guide plates 24 and 25 as the paper 13 moves together with the photosensitive body 1. There fore, the deformation of the paper 13 concentrated to the central part in the width direction can be corrected by the wavy motions of the paper 13 produced in the carrying direction and the paper 13 is expanded. Thus the transfer paper 13 is brought into contact with the photosensitive body 1 while the paper 13 is held in a flat state and occurrence of erroneous transfer is prevented.
