Title: Locus analysis device for moving object
Inventor: SEGAWA TOMOKO
IPC: G06T1/00
Filed: 1991-12-04
Abstract: PURPOSE:To obtain a locus analysis device which can obtain the smooth locus of a moving object through the use of an input unit such as a camera by inputting the object moving from a picture input means and measuring the centroid of the object inputted by means of a position measurement means. CONSTITUTION:The moving object is inputted from the picture input means 1, and the centroid of the inputted object is measured by the position measurement means 2. The time sequence of the centroid which is thus measured is interpolated by an interpolation means 3 so as to obtain the locus. The interpolation means 3 of the locus calculates a distance between the adjacent centroids. When the moving speed of the object is slow, sampling is executed at a prescribed period. Thus, the number of the measured centroids becomes large. There are some measured centroid distances shifted from the correct centroid position owing to the influence of noise. When the inter-centroid distance is smaller than a criterion, a centroid sequence is thinned and interpolated. Thus, the smooth locus can be obtained.

Title: Ink holder
Inventor: HAIGO HIDEAKI
IPC: B41J2/175
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of residual ink and to obtain a holder which can be attached easily to an ink cartridge and is easy of ink injection by using a porous membrane body of a material which swells when ink is injected. SOLUTION: Since PVA sponge 11 attached to an ink cartridge 13 swells when ink is injected and contacts the inner wall of the cartridge closely, it can be set to the cartridge 13 easily. Because of the uniform pore density in each part of the sponge 11, the mobility of ink can be improved, and when the cartridge is used up, the amount of residual ink can be reduced. Especially, since the sponge 11 is formed from polyvinyl formal as a base material, and the pore diameter is controlled to be 100-650μm, the mobility and holding power of ink can be kept stable so that the PVA sponge of high reliability can be provided.

Title: Period/timing generator for ic testing device
Inventor: ITO MASAYUKI
IPC: G01R31/3183
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To use a period/timing generator for IC testing device in a reference clock period other than 2<p> (p=0, 1, 2,...) nS and, at the same time, to more economically use the generator than the case where a data conversion ROM is used. SOLUTION: In a write mode, a divider/multiplier 31 converts period/timing data WD from the outside into data WD' composed of a quotient (a) and a remainder (b) by dividing the data WD by a reference clock period Tc and writes the data WD' in a period/timing memory 20 and, in a readout mode, the divider/multiplier 31 returns data RD' read out from the memory 20 to their original data RD by multiplying the data RD' by the period Tc and gives the data RD to the outside. The memory 20 supplies the quotient (a) of the data RD' at the address designated from a pattern generator to a down counter 3 and the remainder (b) to a phase accumulator 4. The counter 3 is reset to the quotient (a) whenever a zero detector 7 detects zero and makes down-counting one LSB by one LSB at every reference clock.  The zero detector 7 gives a period/timing pulse to a delay circuit 8 whenever the detector 7 detects zero in the count value of the counter 3. The phase accumulator 4 sets the delaying amount of the delay circuit 8 by using the data obtained by accumulating the remainder (b).

Title: Power supply controller for electric vehicle
Inventor: IMAIZUMI KATSUHIRO
IPC: H01M10/44
Filed: 1994-12-26
Abstract: PURPOSE: To enhance reliability in the detection of deposition by making a decision that deposition occurs on a main contactor when the terminal voltage of an auxiliary battery exceeds a predetermined comparison voltage thereby determining occurrence of deposition reliably. CONSTITUTION: When a main contactor 2 is interrupted by a vehicle control unit 10, a deposition detecting section compares the output voltage from a terminal voltage detector 9 for an auxiliary battery 6 with a predetermined comparison voltage (e.g. 13V). A decision is made that a deposition occurs on the main contactor 2 when a voltage exceeding the comparison voltage is detected. Since a DC/DC converter 5 operates continuously when the deposition on the main contactor 2 occurs, occurrence of deposition can be determined reliably based on the continuous operation of the DC/DC converter thus enhancing reliability in the detection of deposition.

Abstract: PURPOSE:To obtain a printer performing high quality printing with effective power use by providing means for controlling power supply to the heating element in a print head according to a calculated conduction time. CONSTITUTION:A print density calculating means M4 calculates print density within a predetermined print range based on an externally provided data. A moving speed calculating means M5 then calculates the moving speed of a print head M1 based on a calculated print density, and a drive control means M6 controls a print head moving means M2 so that the print head moves with thus calculated speed. A conduction time calculating means M7 then calculates conduction time of the heating element M1a in the print head M1 based on the moving speed of the print head M1, and a conduction control means M8 controls power supply to the heating element M1a according to thus calculated conduction time. Since the moving speed of the print head is controlled based on the print density within a predetermined range and power supply time of the heating element is controlled based on the moving speed of the print head, high quality printing is carried out with reduced power consumption.
