Title: Digital control method of load current
Inventor: OBARA MASAKI
IPC: G05F1/10
Filed: 1984-02-24
Abstract: PURPOSE:To perform high-precision current control by storing a digital converted value in a pulse-off state such as a stop in a filter, and performing control on the basis of the corrected value obtained by subtracting the stored value from a digital value during device driving. CONSTITUTION:An AC power source is connected to a load 2 such as a DC electric motor through a stationary type power converter 1 such as a reverse parallel connection thyristor Leonard device. When this converter 1 is controlled, a detector 3 detects a current IA flowing through said load 2 and the detected current is converted by an A/D converter 4 into a digital current ID, which is inputted to a digital controller 5. This controller 5 performs specific arithmetic on the basis of the actual value ID of an inputted load current and a command value to determine the ignition phase of said converter 1. In this case, the output of the A/D converter 4 when no load current flows is read in the controller 5 and stored in a file A, and the corrected value obtained by subtracting it from the load current is used as the actual value of the load current.

Inventor: OBATA MASAO
IPC: F21V8/00
Filed: 1991-02-27
Abstract: PURPOSE:To reduce luminous flux and improve the light utilization efficiency of the lighting device for liquid crystal. CONSTITUTION:A photoconductor 11 is constituted by laminating plural refracting layers N1, N2...Ni which have different refractive indexes and the light which is made incident on a light incidence end surface 13 is refracted by the border surfaces of the respective refracting layers N1, N2...Ni to reach a light projection surface 14 at an angle thetai of incidence which is smaller than the critical angle thetaw. The light is therefore prevented from being reflected totally by the light projection surface 14 and the optical path length in the photoconductor 11 can be shortened.

IPC: G11C11/41
Filed: 1985-02-21
Abstract: PURPOSE:To shorten exceedingly a time required for an address assignment for the purpose of initializing by performing the address assignments for memory cells of a random access memory simultaneously. CONSTITUTION:In the case of a write-cycle for the initializing operation, the address assignment signals which indicate row-line l and column-line m as shown by the signal (1) at A0-A9 are given. When a writing is carried out, a chip selection signal CS shown by the signal (2) is a low level and also a write-signal WE shown by the signal (3) is in a low level. As a result, a gate G1 output level turns out high to make buffers B11-B14 active and buffers B15-B18 inactive. Data are given from input and output terminals I01-I04 and switching cells P0 become conductive. Low level initializing signals S/R are given through switching cells P0 at a line m1 to make a matrix selection possible. Data to be stored through a data input controlling circuit 4 are commonly given from a column/input and output selection circuit 5 to the column line and the common data are stored at store cells assigned as the address.

Title: Liquid phase epitaxial film growth method
Inventor: SAKATA TOSHIO
IPC: H01F41/28
Filed: 1987-02-17
Abstract: PURPOSE:To prevent the deterioration of characteristics due to rough surface of an epitaxial film by moving a vessel having a solution in it as well as a substrate immersed in the solution from a growth region to a liquid removal region having a low temperature, thereby pulling the substrate out of the solution in the liquid removal region. CONSTITUTION:An epitaxial film growth device is equipped with a cylinder 1 as well as heaters 2 that are wound around the cylinder and the temperature distribution in the cylinder 1 is different according to the regions; that is, a growth region A and a liquid removal region B and then the region A is prepared at a region of high temp. and the region B is prepared at the region of low temp. The substrate 6 is immersed in the solution 4 that is held in a crucible 5 made of platinum and a single crystal film having a prescribed thickness is produced at the surface. Once the single crystal film having the prescribed thickness is produced, the crucible 5 is moved to the liquid removal region B by operating an elevating mechanism 10 and at the same time, even the substrate 6 immersed in the solution 4 is moved to the region B by operating the elevating mechanism 9 and as soon as the crucible 5 is moved to the region B, this device permits the mechanism 10 to stop operating. On the other hand, moving of the substrate 6 is continued and its substrate is pulled out of the solution 4 at the region B and then it prevents the development of rough surface of an epitaxial film.

Title: Driving device for optical means
Inventor: KIME KENJIRO
IPC: G02B7/28
Filed: 1985-02-20
Abstract: PURPOSE:To improve the coil using efficiency as well as the orientation properties of the tracking direction of an objective lens, by sliding and turning an axial direction slide/turn member toward a shaft via a drive means based on the focusing and tracking shift amounts of a detected light spot and therefore performing the focusing/tracking control of the light spot. CONSTITUTION:When a focusing shift of a light spot is detected, a current corresponding to this shift amount flows to a coil control coil 17. This current acts on a magnetic flux produced in a gap 50 formed between outside yokes 21a and 21b and an inside yoke 22 by permanent magnets 20a and 20b. Thus a mobile holder 13 is slided toward the axial direction of a support shaft 4. Then an objective lens 1 is moved toward an arrow B for correction of the focusing shift of the light spot. In case a tracking shift of the light spot is detected, a current corresponding to this shift amount flows to track control coils 18a-18d. The current flowing to these coils act on a magnetic flux and the holder 13 is turned round the shaft 4. Then the lens 1 is shifted toward an arrow A for the correction of the tracking shift of the light spot.

Filed: 1989-02-14
Abstract: PURPOSE:To make a display at a fast response speed by switching the output of a driving part between segment output and common output and switching the scanning directions at the time of display operation. CONSTITUTION:The output of the driver part 76 is switched between the segment output and common output and the scanning directions at the time of the display operation are switched. Namely, the output of a register 74 is connected to the output of the driver 76 and the input of the register 74 is switched between common data and segment data with a segment/common switching signal. Consequently, special processing by software is required for either longitudinal nor laterally long display, so the response speed of the display does not decrease.

Abstract: PURPOSE:To make the thickness of deposited film uniform by the procedure in which a deposition chemical is placed either by putting it in a crucible or directly on the hearth of an electron beam evaporation source provided at the lower part of the periphery of a rotary dome for holding an object to be deposited and then the hearth is rotated horizontally under a specific condition, CONSTITUTION:The deposition chemical 2 is placed either by putting it in a crucible or directly on the hearth 12 of the electron beam evaporation source 1 and then a heating (thermion) beam is applied to the chemical while rotating the hearth 12 horizontally around the almost central axle 03-03 of electron beam irradiated. In short, when the chemical 2-placed hearth 12 is rotated with the ratation of the dome 3 holding an object to be deposited, the amount of vapor to be deposited on each portion of the dome is well equalized against the dispersion and fluctuation of the vapor flow and therefore the uniformity and reproductivity of the thickness of deposited films at each portion of the dome can be greatly improved.
