Title: Optical signal transmitter
Inventor: YOSHINAGA HISAO
IPC: H04B10/548
Filed: 1993-02-18
Abstract: PURPOSE:To magnify the distance of transmission of an optical fiber by directly modulating a light source by a suppression signal which has a band of raising the level of a threshold value where an output light causes induced Brillouin scattering. CONSTITUTION:The optical signal from a semiconductor laser light source 1 is modulated with an external modulator 2. At this time, the semiconductor laser beam is directly modulated with the SBS suppressive signal from an induced Brillouin scattering (SBS) suppressive signal generator 5. As the SBS suppressive signal 11, there are a single frequency signal, a signal where a plurality of frequencies are multiplexed, a digital pseudo random pattern signal, etc. When modulating the optical output of a semiconductor laser light source, the band and the intensity of the SBS suppressive signal 11 are selected so that the quality of an transmissive electric signal may not be affected. Hereby, the input power of the output beam to an optical fiber can be enlarged, so the deterioration of distortion can be prevented, and the distance of transmission of the output beam can be enlarged.

Filed: 1988-03-04
Abstract: PURPOSE:To curtail a storage area, and to shorten operation time by calculating the average data of N-pieces of data by using a means to sum two data and a bit shifting means. CONSTITUTION:When the continuous data D1, D2, D3, D4,... are supplied one after another to an input terminal 1, the data D1 is stored in all of storage areas RAM1-RAM3, and a pointer PT is set up in the storage area RAM1. Next, the data D1 is outputted from the storage area RAM1 in which the pointer PT is set up, and the next data D2 is stored. In the storage areas RAM2 and RAM3 other than this, the data (D1+D2)/2 that the sum of the stored data D1 and the input data D2 is shifted by one bit is stored. Then, the pointer PT is set up in the storage ares RAM2. Thus, the data of the storage area RAM3 in which the pointer PT is set up can be treated as the mean value data of the continuous data D1, D2.

Abstract: PURPOSE:To smooth a resultant torque in offsetting both positive and negative signs of torque as well as to reduce the extent of torque variations by forming a cam profile so as to make the lift decreasing period of a cam on one side precedingly operating and the increasing period of a cam on the other succeedingly operating accord with each other in an interval between these cams themselves of different cylinders operating before and after. CONSTITUTION:A hydraulic fluid collected in a hydraulic chamber 20 is put back to another hydraulic chamber 13 by an accumulator spring 21 at the time of lift decrease in a cam 1, making it act on such a force as driving this cam 1 via a cam side piston 7. A rotary sleeve 10 is rotated by a rack pinion mechanism 17, then height in the reciprocating direction of the end of a window 12 is varied to some extent and timing for opening an oil hole 11 is changed, whereby a lift value in a suction-exhaust valve 24 is adjusted. In succession, a lift increasing period in a certain cam and a cam lift decreasing period of another cam of a cylinder opening precedingly to the former are almost accorded with each other, through which both positive and negative signs of cam shaft driving torque are nearly negated with each other and smoothened, and thus any torque variation in the cam shaft is reducible in this way.

Title: Magneto-optical recording and reproducing device
Inventor: HIRAMATSU MAKOTO
IPC: G11B11/105
Filed: 1989-03-07
Abstract: PURPOSE:To achieve desired magneto-optical recording even if a magnetic head is miniaturized by disposing an auxiliary magnetic head on the side of an optical head and concentrating a magnetic field generated by the magnetic head on a focal point of a light beam on a recording medium. CONSTITUTION:The auxiliary magnetic head 7 disposed on the side of the optical head 1 forms an eddy conductive pattern on a plate-like magnetic body 7b possessing a hole 7a passing a light beam 2 to a recording medium 3. At the time of recording, a magnetic head driving circuit 4 drives the head 5 to generate a magnetic field, and simultaneously an auxiliary head driving circuit 6 drives the head 7 to form the magnetic pole to the head 5. Consequently, the magnetic field of the head 5 is concentrated on the focal point of the light beam 2, and prescribed recording can be performed in spite of surface wobbling and a decrease in surface precision. Thus desired magneto-optical recording can be achieved even if the magnetic head having a small-sized inductance is used.

Abstract: PURPOSE:To form a single crystal thin film in high quality by a method wherein, after covering a semiconductor substrate surface with an oxide crystal film, the temperature of substrate in a vacuum vessel is raised to high degree to impress the substrate surface with high pressure for reducing the oxygen void in a deposited film. CONSTITUTION:An oxide single crystal film is deposited while sustaining the oxygen pressure by leading oxygen from an acid degree leading-in nozzle 7 in a vacuum vessel 1. At this time, the oxidation of an Si substrate 6 surface and the etching reaction are balanced with each other on the optimum Si substrate 6 surface state while sustaining the flatness of the surface. After the substrate 6 is covered with the oxide single crystal, the temperature of the substrate 6 in the vessel 1 is raised to high degrees for accelerating the growth of the deposited film. Through these procedures, the substrate 6 surface is impressed with high pressure to reduce the oxygen void caused in the oxygen contained in the deposited film as well as to make the molecules evaporated on the substrate 6 migrate for accelerating the quadratic layer deposition so that a single crystal thin film in high quality may be manufactured.

Filed: 1979-04-28
Abstract: PURPOSE:To increase the working speed in comparison with the single-type A/D converter, by constituting an A/D converter having a large number of bits with use of plural units of the A/D converter of a small number of bits. CONSTITUTION:The input signal is led in via buffer amplifer 3 to be supplied directly to A/D converter 1 and to A/D converter 2 via amplifier 4 each. The digital output signals of converters 1 and 2 are sent to calculator 7 via gate circuits 5 and 6. In this case, circuit 5 is turned on and off by the decision signal sent from circuit 8 which detects the overflow of converter 2. While circuit 6 is turned on and off by the signal obtained by inverting the decision signal through NOT circuit 9. Thus the output of converter 2 is extracted via circuit 5 in the period during which converter 2 has no overflow and based on the decision signal; while the signal is extracted via circuit 6 when converter 2 has the overflow respectively. As a result, the working speed of the complex converter can be increased in comparison with the single converter.
