Inventor: SUNAHARA KAZUO
IPC: C30B27/02
Filed: 1984-11-20
Abstract: PURPOSE:To enable the use of a crucible for a long period, and to produce a group III-V compound single crystal free from inpurities, by pulling up a single crystal of a group III-V semiconductive compound from molten liquid in a crucible made of ZrB2. CONSTITUTION:A pressure vessel 1 is pressuzied with N2, etc., and a molten GaAs liquid 3 is formed in the crucible 2 with a carbon heater 5. The surface of the molten GaAs is covered with molten B2O3 liquid 4. The seed crystal 6 attached to the lower end of the upper driving shaft 8 is made to contact with the molten GaAs liquid 3, and the upper driving shaft 8 is pulled up under rotation to the direction opposite to the rotation of the lower driving shaft 9 supporting the crucible 2 to effectthe growth of a GaAs single crystal 7. In the above process, a crucible composed mainly of ZrB2, preferably having a ZrB2 content of about >=70%, especially about >=90% is used as the crucible 2. A GaAs single crystal free from impurities dissolved from the inner wall of the crucible 2 can be produced and the life of the crucible 2 can be prolonged by this process.

Title: Spray type etching device
Inventor: SENMA KAZUYOSHI
IPC: C23F1/08
Filed: 1984-11-19
Abstract: PURPOSE:To equalize the etching depth of a work piece, and to improve the roughness of an etching surface by enlarging a diffusion angle from plural diffusion nozzles, and forming an atmosphere in which a jetted etching liquid interferes with each other.

Title: Elevator controller
Inventor: MITSUNE SHUNSUKE
IPC: H02P27/06
Filed: 1987-09-30
Abstract: PURPOSE:To reduce electromagnetic noise, by varying duty factor corresponding to the magnitude of a current command and operating an elevator with such duty factor as higher harmonic is minimized. CONSTITUTION:A primary current command I1 is fed to a duty factor command circuit 15 in order to determine duty factor of an inverter 4. When duty factor lambdais set to such level lambda0 as higher harmonics are minimized, peak current can not be outputted and thereby the duty factor lambda is varied corresponding to the magnitude of the current command I1. Consequently, output higher harmonic component can be minimized within a range where the current level is not high with maximum current supply capacity being maintained. An elevator requires maximum current only when the load is at the maximum during acceleration and higher harmonic component is minimized normally, resulting in improvement of torque ripple as well as electromagnetic noise.

Title: Position control mechanism for automatic analyzer
Inventor: IKEDA TOSHIYUKI
IPC: G01N35/00
Filed: 1984-11-19
Abstract: PURPOSE:To stop a subject at a prescribed position with high accuracy by reversing the revolving direction of an AC motor for a fixed period of time when said motor is stopped in response to the level of the inertia given to the shaft of the AC motor of a position control mechanism. CONSTITUTION:For the signal of an output line 2 of a mechanism control circuit 1, a 1-shot pulse generating circuit 4 produces a signal which serves as a revolving instruction just for the time T in case the CW direction revolving instruction is changed to a stop instruction level for CW direction revolution. This signal gives the revolving power of the CCW direction to a motor for the time T via a CCW side driving AC switch 10. While the revolving signal given from the circuit 1 in the CCW direction through a CW side circuit signal line 3 is changed to the level of the CCW direction stop instruction signal from the level of the CCW direction revolving instruction signal at a point (b). In such a case, a pulse width setting circuit 9 produces a pulse of a prescribed time width. Thus the CW direction revolving power is given to the motor for the time T via a CW side driving AC switch 7 as shown by an output waveform.

Title: Image processor and image processing method
Inventor: TERAI HIROMITSU
IPC: G06T3/00
Filed: 1989-09-20
Abstract: PURPOSE:To improve image drawing operability by applying the Bessel function approximation to a line picture part stored as a curve based on the spot coordinates stored in a memory means related to the line picture part. CONSTITUTION:The spot coordinates which specify the segments to be reformed as a line picture and the line type information are stored in the memories 22 and 23 with the mutual relation secured between them via the data number added to the spot coordinates. Then a Bessel function approximation process is carried out based on the spot coordinates related to the part showing that the line type information is equal to a curve. Thus a curve of the line picture is produced with approximation. Therefore a program drawing the line picture is required just to refer to a storage area related to the spot coordinates when the spot coordinates serving as a joint point of the line picture is changed and a desired segment is drawn. As a result, the performance of an image interface is improved.

CONSTITUTION:A photocoupler 201 branches a signal wavelength-multipled by an optical fiber 101 into four to be supplied to optical wavelength converters 311 to 314. In the 311 to 314, an arbitrary wavelength is selected from the four wavelength- multipled wavelengthes to be converted into wavelengthes with lambda1 to lambda4 by the control from the outside. After inputted to the lambda1 to lambda4 and a photocoupler 211 to be matched, they are branched into four and supplied to optical wavelength converters 411 to 414. Photocouplers 211 to 214 takes charge of the connection function with the switches of first and second stages. Thus, the circuit scale necessary for the connection between stages is reduced since only the photocoupler is utilized to the connection between stages of the wavelength division optical switch circuit network for multistage construction.

Title: Dot printer
Inventor: SAKAIDA ATSUO
IPC: B41J2/30
Filed: 1989-09-20
Abstract: PURPOSE:To prevent a first dot from becoming blurred or from being omitted by making a first driving voltage applied to a piezoelectric element during continuous dot printing higher than that of a second dot and subsequent ones to increase a first impact force of a printing wire. CONSTITUTION:A control circuit TC thrns on a transistor TR11 at a first dot printing of a continuous dot printing so that a high voltage V1 which can be obtained by connecting DC sources E1 and E2 in series is applied to a stacked piezoelectric element 31, whereas said circuit TC turns on a transistor TR21 at a second printing and subsequent ones so that voltage V2 which is lower than the voltage V1 is applied to said element 31. The deformation energy of the element 31 at the first dot printing is larger than that at the subsequent printing. Consequently, even if, at the first dot printing, part of deformation energy of the element 31 is consumed to move constituent members of a printing element 30 against static friction, impact forces of a printing wire 43 are sufficiently strong because of the remaining deformation energy, preventing thereby the first dot of dots in succession from becoming blurred or from being omitted.

Thereby, a clock OSDCLK having the original oscillation frequency until the start position and a frequency in accordance with magnification from a display position can be obtained. Therefore, the display start position can be made constant independently of magnification by controlling the display of a character based on this clock OSDCLK.
