Title: Printer, plotting device and method
Inventor: KUMADA SHUICHI
IPC: B41J2/485
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To plot a proper diagram even if a line is thickened by inputting enlarging ratio to enlarge a line pattern in the horizontal direction and providing a means to plot the line pattern enlarged in the horizontal direction based on the enlarging ratio. SOLUTION: When line pattern information including line width of the line pattern is received from a host computer, the enlarging ratio corresponding to the line width is preliminarily stored as a table in a ROM of a main device. In addition, when the line pattern information including the enlarging ratio of the line pattern is received from the host computer, the line width corresponding to the enlarging ratio is preliminarily stored as the table in the ROM of the main device. Therefore, in case of the line with the same line pattern and different line width, for example, the enlarging ratio 1 and the enlarging ratio 5, since the enlarging ratio is varied according to the line width, a good plotting result in appearance is obtained.  Thus, the line pattern is also enlarged in the horizontal direction with the specified enlarging ratio according to the specified line width and a proper plotting pattern is printed and plotted according to the line width.

Title: Eccentricity correcting method for disk medium
Inventor: MIZUKAMI MAKOTO
IPC: G11B7/095
Filed: 1991-11-20
Abstract: PURPOSE:To quickly correct the eccentricity by counting the number of zero- crossing points on a position error signal per rotation period and calculating the extent of eccentricity for disk medium attachment in accordance with the counted value. CONSTITUTION:A zero-crossing pulse counter 32 counts a number No of zero- crossing pulses between index pulses and transfers it to a microprocessor 33. A sine wave eccentricity correction signal which has a maximum signal amplitude sufficient for correction of the extent of eccentricity is generated by the microprocessor 33. This generated eccentricity correction signal is applied as an analog quantity to a lens actuator control circuit. In the third stage of eccentricity correction, the eccentricity correction signal is generated in the state shifted from the index by a phase angle phi0, and a number N of zero-crossing points on the position error signal is counted in this state. N=0 indicates that the eccentricity is corrected most suitably.

Title: Liquid level measuring device and liquid level measuring method
Inventor: KATAYAMA HIDEYO
IPC: G01F23/14
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To simply and accurately observe the ground water level by providing a gas guide pipe, and measuring the water head pressure while observing gas pressure. SOLUTION: When the inert gas with the prescribed secondary pressure is introduced into a gas guide pipe 1 via a guide opening/closing section 6, the pressure in the gas guide pipe 1 is gradually increased. The liquid level in the gas guide pipe 1 is pressed down to the level balanced with the gas pressure by the introduction of gas. When gas is further introduced, the gas pressure surmounts the liquid pressure, and gas is leaked into the liquid from the tip of the gas guide pipe 1. When the pressure change is observed by a pressure measurement section 7, the pressure transfer in the gas guide pipe 1 is stabilized at the equilibrium state after the highest pressure is attained at the time of a gas leak. A guide controller 9-2 controls the guide opening/closing section 6 to interrupt the feed of gas at this timing.  The liquid level is calculated by an arithmetic process section 9-3 from the so-called water head pressure observed at this time. The drilled hole diameter of a ground water level observation well can be reduced, and observation can be simply and accurately made.

Abstract: PURPOSE:To prevent the deterioration and residual image of the picture element of a color liquid crystal panel by constructing the device so that voltage having a same polarity cannot be applied to the RGB picture elements on the color liquid crystal panel for a period of 2H. CONSTITUTION:An input video signal in a PAL broadcasting system is led to a video demodulation circuit 1. The input video signal is demodulated by the demodulation circuit 1 to generate the R, G and B signals, and these signals are processed to a state corresponding to a color liquid crystal panel 7 by built-in clamping circuit, white balance circuit and gamma correction circuit, and outputted to an inversion circuit 2. The inversion circuit 2 inverts the polarity of the R, G, and B signals to generate R', G' and B' signals and outputs them to an RGB alternate circuit 3 along with the R, G and B signals. At this time, since a CLY signal providing the timing of alternatively switching between the R, G and B signals and the R', G' and B' signals to be led to the alternate circuit 3 is forcedly inverted, the voltage having the same polarity can be prevented from being applied to the rGB picture elements on a panel 7 for a period of 2H.
