Title: Method and apparatus for determining reference position in micro indentation hardness tester
Inventor: HAYASHI HIROTAKA
IPC: G01N3/42
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To obtain a micro indentation hardness tester in which the reference position is set automatically for a presser and a contactor. SOLUTION: Electrode plates are applied to the opposing faces of a contact lever 4 and a presser lever 2 to form first and second capacitors. A CPU 31 receives the capacitance from each capacitor and produces a control current for elongating/contracting a PZT (laminated piezoelectric actuator) 30. Consequently, the contact lever 4 is turned about a shaft 5 such that the capacitance is equalized for both capacitors thus realizing automatic setting of reference position for the presser and a contactor.

Title: Manufacture of ceramic product
Inventor: ANDO SHIGERU
IPC: B28B1/26
Filed: 1991-11-07

Title: Image forming apparatus
Inventor: ITO TATSUYA
IPC: B41J2/06
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To prevent friction between a recording head and an a recording material caused by the curling and waving of the recording material by mixing magnetic powder into ink and installing a member with magnetic force on the platen side. SOLUTION: A magnet 8 is arranged at a position below a platen 6, and ink for forming an image which is mixed with fine powder of a magnetic material (ferrite, magnetite) is used. A recording material 1 which has absorbed the ink and swelled is attracted to the platen 6. Accordingly, curling is not formed, and the generation of friction between the recording material 1 and the recording head 2 can be prevented. In this process, since the amount of the magnetic material contained in the ink increases with the increase of the concentration, magnetic force is strengthened to increase the attraction to the platen 6. Besides, a part of the recording material which has absorbed the ink and swelled becomes less rigid due to wetting and is easily affected by the action of magnetic force, well effecting the absorption of curling.

Title: Assembler system
Inventor: MIZUSE HARUMI
IPC: G06F9/44
Filed: 1987-12-18
Abstract: PURPOSE:To reduce the assembling time of an assembler system by performing skipping operations until the assembler automatically detects a corrected point and assembling a corrected module and the modules after the corrected module. CONSTITUTION:The block 31 shows a source program divided into modules A-C and the block 32 shows object files A'-C' corresponding to the modules A-C. Produced times Ta-Tc and Ta'-Tc are respectively recorded in the modules A-C and files A'-C'. The recording block 41 is an SEQ file and the editing order of modules in a source program to be assembled is recorded in the block 41. An assembler compares the producing times in the module A and, after confirming that the OBJ file is newer and the file A' is the first produced file, skips assembling of the modules A and B. In the case of the module C, the assembler starts the assembling operation after judging that correction is performed on the module C since the ASM file is newer.

Title: Washing machine with water reserving trough
Inventor: YAMAKAWA KIICHIRO
IPC: D06F39/08
Filed: 1988-12-19
Abstract: PURPOSE:To use ditergent liquid effectively, raise the bath ratio (amount of washing liquid vs amount of wash) for the wash, and prevent drop of the washing ability by determining the water level according to the load amount, and making the level higher than this determined in case the liquid is used again. CONSTITUTION:According to a load amount sensing program, a rotary vane 5 is inverted for a short time, and the number of revolutions N is sensed by counting ON/OFF reversals on a reed switch 45 at this time. Because the resistance to the rotary vane 5 is higher with larger load amount, the number of revolutions per short time is lessened. A microcomputer 27 judges whether the stored liquid in a reservoir trough 12 is ditergent liquid after washing or a rinse liquid from the set condition of the store flag, and also judges whether the set water level is high, and in case the ditergent liquid is stored and at the same time, set to small amount, low, and middle water level, the set water level is changed to the water level one step higher.

Title: Semiconductor device
Inventor: KUDO NOBORU
IPC: H01L29/866
Filed: 1990-11-26
Abstract: PURPOSE:To prevent permanent breakdown of a protection diode due to aluminium punchthrough by forming a deeper diffused region of the same conductivity type as a cathode diffused region in the periphery thereof in the same process as the base of a double diffused MOS(DMOS) transistor. CONSTITUTION:A diffusion profile of an N-type base region 3 is determined by optimizing the characteristic of DMOS. In this case, the depth of cathode diffused region of a protection diode is determined by an N-type base region 3 which is deeper than an N-type diffused region 4. Thereby, aluminium forming a cathode electrode 6 of the protection diode moves through a semiconductor substrate due to the heat generated when the protection diode operates and it reaches a P-type well 2 when the cathode diffused region is shallow, generating the permanent breakdown. But such permanent breakdown can be prevented by shallowing the cathode diffused region.

Filed: 1993-12-21
Abstract: PURPOSE:To identify the difference of a color in an input picture and to precisely and easily generate a closed area by converting the input picture into color space expression for respective picture elements and sequentially comparing conversion data in adjacent picture elements with the indicated picture element as a center. CONSTITUTION:A color conversion means 1 converts the inputted picture into color space expression expressed by brightness and color information. An indication means 2 indicates one picture element in the inputted picture, and a discrimination means 3 sets the indicated picture element as a reference picture element and compares the brightness and color information of the reference picture element with those of the adjacent picture element. The differences of brightness and color information are discriminated to be within a prescribed range or not. When the differences are within the prescribed range, the picture element is recognized to be within the same area. When the differences are out of the prescribed range, it is recognized to be the picture element of a different area, and the area is discriminated with the picture elements which are sequentially provided as the reference picture elements. Thus, comparison and discrimination in the unnecessary area out of the area becomes unnecessary, discrimination time can be shortened and a precise mask which cannot be obtained in the comparison of RGB color space expression information can be obtained.
