Title: Data write system
Inventor: KAWANA SHIGEYUKI
IPC: G06K17/00
Filed: 1986-11-13
Abstract: PURPOSE:To shorten a time required for writing data into an IC card by storing data written into a data memory in a 1st storage means, then storing the data in a 2nd storage means, comparing data in the 1st storage means with that in the 2nd storage means and using written data when the coincidence is obtained. CONSTITUTION:It takes time at a read/write control part 16 to write data into data memories such as a EPROM and a E<2>PROM used for the IC card. Consequently the control part 16 compares data to be written with data that is temporarily written in the data memory 29, and if they are coincident, the part 16 uses the stored data as data to be written normally as it is. If not, first the part 16 writes data in a minimum write time. However the data cannot be written in that time, the part 16 prolongs the write time and again writes the data. Thus, compared with a system that uniformly determines write time, the time required for writing data can be substantially shorten even if data is actually written.

Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To provide an interferometer with high contrast in interference fringes capable of measuring the shapes of surfaces and wavefronts with high accuracy without a reference surface by forming interference fringes out of a measuring beam of light and a reference beam of light from the second mask. SOLUTION: Light emitted form a light source 9 and transmitted through a diffracting pinhole becomes spherical waves with little distortion and becomes incident onto a specimen as a measuring beam of light 21. The light incident onto the specimen and transmitted or reflected there is converged on a diaphragm and is transmitted through the diaphragm. The light emitted from the light source 9 and transmitted through the diaphragm reaches a test surface 8. The beam of light which has reached the test surface 8 is reflected by or transmitted through the test surface 8 and is converged on a diffracting pinhole. The beam of light 21 which has reached the diffracting pinhole is transmitted through the diffracting pinhole becomes spherical waves with little distortion and becomes a reference beam of light 20.  As the interference between the reference beam of light 20 and the above-mentioned measuring beam of light 21 forms interference fringes, it becomes possible to measure the test surface 8. There is no light beam dividing means between the test surface 8 and a mask 4 in this way, it becomes possible to perform measurement without being affected by errors of a light beam dividing means.

IPC: B60W10/10
Filed: 1987-10-27
Abstract: PURPOSE:To perform optimum control of gear shift, by a method wherein car speed sensitive gear shift characteristics using an engine load and a car speed serving as a parameter on a running road with a low gradient and only a car speed serving as a parameter during detection of acceleration and deceleration on a low gradient is selected. CONSTITUTION:A gear shift characteristics varying means C selects fundamental gear shift characteristics using an engine load and a car speed, serving as a parameter, when the gradient of a running road detected by a gradient detecting means B is low, and controls gear shift of an automatic speed change gear E through a gear shift control means D based on the gear shift characteristics. Meanwhile, under a state in which it is detected that the gradient of a running road is high, when acceleration or deceleration of a vehicle is detected by means of a detecting means A, a gear shift characteristics varying means C shifts it to car speed sensitive gear shift characteristics using only a car speed serving as parameter. This constitution performs normally optimum control of gear shift, and enables reduction of a feeling of physical disorder imparted to a driver.

Title: Ink jet recorder
Inventor: MURAI TAEKO
IPC: B41J2/135
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To improve image quality by injecting an ink droplet obliquely in an opposite direction to a moving direction of a recording head, thereby reducing a deviation of a dot position to a deviation of an ink injecting direction. SOLUTION: A recording head 6 is disposed obliquely from a direction perpendicular to a moving direction of the head 6 to discharge an ink droplet 49 obliquely in an opposite direction to the moving direction of the head 6. At the time of moving the head 6 in a direction of an arrow at a moving speed V0 , the droplet 49 injected toward a direction B0 obliquely to the moving direction of the head at an ink droplet discharging speed Vj is shot on a recording medium at the head moving speed V0 to form a dot at a shot position b0 . In this case, dot shot positions in the case of deviating the injecting direction of the droplet 49 like B1 , B2 become b1 , b2 . Deviations of the shot positions due to the deviation of the injecting direction can be reduced.  Further, a deviating amount in the injecting direction can be reduced as the head moving speed is accelerated, thereby rapidly recording with high quality.

Title: Method and device for inputting/outputting coordinate
Inventor: TSUBOKI MITSUO
IPC: G06T11/80
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To make inexpensively inputtable/outputtable coordinates by using the picture data of an object whose coordinates are to be inputted/outputted. SOLUTION: Plural coordinate data corresponding to picture data whose coordinates are to be inputted/outputted are stored in a storage device 3 and an arithmetic unit 6 automatically calculates a coordinate transforming parameter by the positional relation of four coordinate data in total, i.e., two optional coordinate data which are mutually different out of the coordinate data stored in the device 3 and two picture data system coordinates obtained by an indicator 4 for visually indicating the corresponding coordinates of respective picture data. Thus coordinates are inputted/outputted based on the picture data system coordinates and coordinate transformation between plural coordinate data by using the parameter.

Title: Mode verification method for bidirectional terminal in scan path
Inventor: YAMAUCHI TAKASHI
IPC: G11C29/12
Filed: 1991-09-21
Abstract: PURPOSE:To exactly verify a bidirectional input/output mode at a high speed in the course of scan operation. CONSTITUTION:In an initialization processing 2, an indefinite value is set to an input terminal varied at the time of scan shift operation, and a definite value is set to an input terminal which is not varied. In a definite value propagation processing 3, a newly generated definite value is propageted to a connecting destination. In an output value determination processing 4, an output value of an element is determined by only the definite value propageted to the input. In a decision processing 5 for generation of a new definite value, in the case there is an element in which a definite value is generated newly in the output by the output value determination processing 4, the processing advances to the definite value propagation processing 3, and when not, the processing advances to an input/output mode verification processing 6. In the input/output mode verification processing 6, whether an input/output mode switching signal of a bidirectional terminal is decided definitely or no is varified. In this case, it can be verified that the input/output mode of the bidirectional terminal can be verified without simulating a shift operation of a scan path and such a problem as a bus fight, etc., in not caused.
