Title: Method for controlling optical disk device
Inventor: SOEJIMA TOSHIYUKI
IPC: G11B7/12
Filed: 1989-08-09
Abstract: PURPOSE:To prevent the recording of imperfect data by averting the execution of recording/reproducing of data when the optical abnormality of the optical pickup device is decided by the self-diagnosing at the time of starting. CONSTITUTION:The output light signals from photodetecting surfaces 10a, 10b of a photodetector 10 are respectively applied to an adder 11 and a subtractor 12 and the sum signal SS from the adder 11 is inputted to a focus servo control section 13. The differential signal DS from the subtractor 12 is inputted to a control section 13 and an amplitude adjusting circuit 14. The signal DS is applied to a window comparator 15 after the amplitude adjustment at the circuit 14. The comparator 15 outputs the detection signal S3 as to whether the amplitude value of the input difference signal DS exceeds a prescribed range or not to a control section 16. The control section 16 announces the infeasibility of the data recording/reproducing to the host device, etc., by judging that the optical abnormality arises when the change in the signal S3 is not detected for the prescribed period of time. The control section does not thereafter receive the data recording/reproducing command from the host device.

Filed: 1987-08-18
Abstract: PURPOSE:To realize an effect sound with slow changing speed without increasing the length of coefficient word of signal processing without complicating the operation of a controller by providing a control signal output terminal capable of outputting a signal subject to prescribed processing in a control data format in addition to a signal input/output terminal and a control signal input terminal. CONSTITUTION:A 2nd signal processor 6, based on information fed from a controller 8 via a control signal input terminal 7, outputs a coefficient (e.g., data of sound volume) required for the processing by a 1st signal processor 3 to the 1st signal processing unit through a control signal output terminal 5 and a control signal input terminal 4. The signal processor 3 uses the coefficient received in this way to process the signal inputted from the signal input terminal 1 and outputs a signal to be processed to a signal output terminal. In this case, as the sampling frequency for the 2nd signal processor 6, a low frequency to cope with a change in the effect sound is selected.

Title: Method for producing gaas single crystal and apparatus thereof
Inventor: WASHITSUKA SHOICHI
IPC: C30B27/02
Filed: 1985-09-19
Abstract: PURPOSE:To produce a high-quality GaAs single crystal having uniform electrical properties as a whole, by pulling up a GaAs single crystal from molten GaAs by a liquid-encapsulated high-pressure pull-up method while keeping the composition of GaAs in the molten liquid in a definite state during the pulling up operation. CONSTITUTION:A molten GaAs 6 having an initial molar ratio of Ga/As of 0.96-0.98 is put into a crucible composed of the outer crucible 8 and the inner crucible 9 and placed in a high-pressure vessel 1. A GaAs single crystal 5 is pulled up from the molten liquid 6 while rotating the crucible and the crystal pull-up shaft 2. In the above procedure, the weight of the pulled up GaAs crystal 5 is measured by the detector 10 and the signal is inputted to the calculator 11. The calculator 11 calculates the solidification ratio of the crystal 5 from the inputted data, estimates the composition of the residual molten liquid 6 and calculates the deviation of the composition from that of the initial molten liquid. Metallic Ga 18 stored in the Ga reservoir 12 is supplied in molten state to the crucible according to the calculated deviation data to decrease the deviation to zero. The GaAs single crystal produced by this process has high quality and uniform electrical properties throughout from the top to the tail of the GaAs single crystal 5.

Therefore, when a light source for scanning a picture to be copied is uneven, etc., in light quantity and unevenness is produced in the density of a copied picture, the exposure quantity to a photosensitive body 50 can be uniformized. Moreover, while the supporting body 54 and destaticization slit 64 interfere with each other, the supporting body 54 does not block the rays of light passed through the slit 64 and appropriate destaticization can be performed on the leading and tailing edges of copying paper, since the supporting body 54 is transparent. Therefore, the slit width of the exposure slit can be changed and the exposure and destaticization slits can be provided adjacently to each other.

Title: Recording method for recorder with platen drum
Inventor: TAKEDA FUMIO
IPC: B41J2/325
Filed: 1986-09-01
Abstract: PURPOSE:To prevent recording lines from being varied due to transmission errors present in a driving system, by causing a counter for counting the number of rotational angle detection pulse signals to generate a recording signal each time the counted number reaches a number corresponding to one revolution of a motor, and matching a recording period for driving a recording head to the rotating period of a worm. CONSTITUTION:A rotational angle of a motor 7 is detected by an FG 15, and the number of detection signals from the FG 15 is counted by a counter 16. When the counted number reaches a number corresponding to one revolution of a worm, the counter 16 sends a signal fro recording to an MPU 17. The MPU 17 reads a one-line amount of data of images to be recorded from an image memory 18, and sends the data to a thermal recording head 4. Then, the MPU 17 determines printing energy based on data read from a ROM 19, and drives a driver 20 for energizing resistors 16 of the head 4 for a period of time required for applying the printing energy. As a result, line width and line interval are made to be constant, on a logical basis, and images with a uniform density can be obtained.

Title: Power unit with current value abnormality detecting function
Inventor: NOZAWA MASAJI
IPC: G05F1/00
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To set a value for overcurrent detection matching with an used current value on a load side irrelevantly to a load device in use by calculating the used current value of the load device from a load current value measured after the power source is turned on. SOLUTION: When a system is powered on, the used current value of the load device 4 is calculated and overcurrent detection values of power units 1 and 2 are set according to the calculated value. When the current value of a regulator 6 exceeds the set overcurrent detection set values, an alarm of the abnormality is outputted. Thus, the overcurrent detection values are set each time the power source is turned on, so even if, for example, the load-side system is expanded, current values corresponding to its used current value can be set as current detection values.
