Title: Semiconductor laser device
Inventor: FUJISAKI YOSHIHISA
IPC: H01S5/00
Filed: 1983-09-14
Abstract: PURPOSE:To extremely reduce the variability of element characteristics by reducing the variability of the width of an active layer with forming the low electric resistance, the low oscillation thereshold value and the good shape of beam. CONSTITUTION:A clad layer 5, an active layer 10 of a stripe region and a second clad layer 9 are formed on a crystal of a substrate 6 in the above order. At this time, the active layer 10 or the vicinity including said layer 10 is held by the crystal plane making an angle of 90 deg.+ or -10 deg. with a main surface of the active layer 10 from the both sides. The upper surface of the clad layer 9 is formed more widely than the active layer 10. Consequently, the variability of the active layer 10 in a wafer becomes + or -0.1mum or less and the yield of elements fabrication is increased.

Title: Plane shape control method for thick plate rolling
Inventor: CHICHIHARA YASUSHI
IPC: B21B37/28
Filed: 1985-07-30
Abstract: PURPOSE:To enable a shape control to be more accurate for each repeating of rolling by measuring the plane shape of a thick plate after rolling and correcting a profile variation amount in the thickness direction for a succeeding thick plate rolling based on the measured information. CONSTITUTION:A necessary profile variation amount per unit length in the thickness direction and a roll opening revision value for a shape control in a forming pass are calculated. The plane shape of a steel plate rolled based on the roll opening revision value is measured by a plane shape recognition device. Then, a profile variation amount in the thickness direction for a succeeding thick plate rolling is corrected based on the measured information, so that rolling with a higher accuracy is performed because the properties of a thick plate and the characteristics of a rolling mill are fed back based on actual rollings to a rolling for the same kind of thick plate.

Filed: 1990-06-28
Abstract: PURPOSE:To implement preceding line replacement processing automatically at a high speed by providing a storage device able to store an image data by 2 lines and revising an area from which the image data is read with a switching signal as required. CONSTITUTION:With a code data inputted to a code decoding section 11, the code data is decoded and the result of decoding is outputted to an image generating section 12.

Title: Aqueous slurry of crystalline aluminosilicate having improved suspension stability
Inventor: AIMOTO MICHIYUKI
IPC: C09K23/52
Filed: 1981-10-23
Abstract: PURPOSE:To obtain aqueous slurry of zeolite having improved suspension stability, by using polymer or copolymer of a specific styrenesulfonate as a dispersion stabilizer for the aqueous slurry of zeolite.

Title: Generating method of buoyancy energy applying irregular contraction and repulsive force of gas generated by transferring compressed liquid to gas
Inventor: TAKAHASHI TOSHIAKI
IPC: F03B17/00
Filed: 1979-12-25
Abstract: PURPOSE: To obtain high energy by applying a phenomenon of irregular pressure change which generates when a gas is pressurized by a liquid, etc.  
     CONSTITUTION: An air contained in a gas compression injection device 3 is rapidly compressed by means of a liquid pressure pump 5 whose air squeeze-out quantity is fixed. The contact surface of a compressed air pent up by water pressure significantly exceeds a pressure value, pushes up a check valve 6, finds its way into a water tank 1 and turns to a buoyancy energy. The gas compression injection device 3, as a reaction, is rapidly decompressed and in addition, the liquid pressure pump 5 ceases a squeeze-out action, causing a back flow. As a result, a gas pressure inside the gas compression injection device 3 drops sharply temporarily partly because of a reaction from compression. At that time, the second compressed air 4 is automatically sucked into a compressed air injection device 3, utilizing a pressure differential.

Title: Production system for address information
Inventor: INOUE ATSUKO
IPC: G06F17/22
Filed: 1989-06-30
Abstract: PURPOSE:To simplify the input of the address data to produce the data on a transmission goal based on the address data containing the input name and address and the print information set to the address data. CONSTITUTION:An address data storage part 1 stores the address data containing the input name and address.

Title: Preview type tracking servo device
Inventor: KUSAMUTA YOSHITOSHI
IPC: G11B7/09
Filed: 1985-07-31
Abstract: PURPOSE:To reduce disturbance in case of a flaw in a disk by employing a preview type tracking servo circuit. CONSTITUTION:When a main beam M is right above a track (n), an auxiliary beam E is set on one adjacent track n+1 and an auxiliary beam F is set on the other adjacent track n-1. The detection of a flaw by the auxiliary beams E and F is carried out on the track n+1 before the track (n) where the main beam is positioned and the flaw is previewed before the main beam M traces the flaw. A preview circuit 1 detects the presence of the flaw by a band-pass filter 11 from a track that the main beam traces and a delay circuit 12 delays the detection output so that it is timed with the tracing of the flaw by the main beam, thereby supplying a correcting value corresponding to the extent of the flaw to a servo circuit 2 from a trailing-stage absolute value amplifying circuit. The servo circuit 2 decreases a loop gain according to this correcting value to operate so that the position and angle of a head are not corrected improperly.

Title: Optical disk device
Inventor: OKAMOTO KIYOSHI
IPC: G11B7/085
Filed: 1994-07-21
Abstract: PURPOSE:To improve reliability by controlling an acceleration-deceleration operation while predicting a point where a tracking error signal becomes a zero-cross and making an optical system jump correctly to a target track. CONSTITUTION:When a tracking instruction is inputted to a signal processing part 6. a CPU 8 transmits an acceleration signal to an actuator 12 via a D/A converter 11 and accelerates a motor by impressing acceleration pulses. Succeedingly, the tracking error signal is inputted to the CPU 8 via an A/D converter 5 and is also stored in a memory 9 and when the zero-cross of the error signal is predicted at the time of a next sampling time by performing an operation with a value stored previously, the CPU 8 sets a deceleration pulse value from required data to transmit it the actuator 12 via the D/A and then decelerates the motor. This step is repeated untill the deceleration pulse becomes zero every time when the tracking error signal is sampled. Thus, a jump operation being correct and having high reliability is performed without being affected by disturbance.

CONSTITUTION:A substrate 2 containing a device 1 to receive the control of temperature is fixed to a heat sink 6 with a space and in a heat insulating way. An expanding/ contracting container 7 set between the substrate 2 and the sink 6 consists of a bellows 8 and a contact plate 9 which touches and detouches the sink 6. A working fluid  10 is enclosed into the container 7. A projected part 14 is formed at a part on the  surface where the container 7 of the substrate 2 is fixed to always be dipped in a  liquid phase 13 of the fluid 10. The heat generated from the device 1 is transmitted to  the substrate 2 and then to the phase 13 through the part 14 of the substrate 2. The  phase 13 is heated up to a level higher than a prescribed temperature, and the vapor  pressure increases to extend the bellows 8 and expand the container 7. As a result, the  plate 9 is pressed to touch the sink 6 to discharge the heat. Thus the temperature of  the device 1 is automatically controlled.
