Title: Document processing device
Inventor: UENO HIDEO
IPC: G06F17/21
Filed: 1993-12-27
Abstract: PURPOSE:To provide a document processing device which can move a cursor to the upper or lower display position for display of the image of an input document and can improve the up-down shift function of the cursor. CONSTITUTION:A text memory stores 'A-F, H-M, V-Z, 1-5' and the line feed codes. When a cursor pointer points the storing address of the position of character 'C', a cursor K is displayed between characters 'B' and 'C'. When a cursor down-shift key is operated, the cursor pointer points the storing address of the position of character 'K' of the next line corresponding to the least shift extent data that is closest to the present display position of the cursor K. Therefore the cursor K is displayed between characters 'J' and 'K'.

Abstract: PROBLEM TO BE SOLVED: To obtain a power converter for solar battery power generation which can expand an operatable voltage range and efficiently convert DC power from a solar battery into AC power. SOLUTION: When the DC voltage of the solar battery 1 is included within a fixed range, a maximum power follow-up control circuit 7 increases/decreases the DC voltage of the solar battery 1 within the fixed range based upon a solar battery characteristic curve, controls the voltage so that AC power to a power system is maximized, and when the DC voltage of the battery is less than the fixed range, a DC voltage fixed control circuit 15 controls the DC voltage of the battery 1 so as to be set to the lower limit value of the fixed range based upon the solar battery characteristic curve. When the DC voltage exceeds the fixed range and the characteristic curve intersects with a conversion power upper limit curve at two points, an operatable point searching control circuit 16 controls voltage so that a point having lower voltage out of the two points is set as an operation point.

Abstract: PURPOSE:To measure flowrate and viscosity of fluid in a pipe by arranging a plurality of sensors having heat generating action and temperature measurement action in a pipe, introducing from the upstream side different fluid with a different temperature from the pipe fluid and measuring moving time of the fluid, sensor temperature and fluid temperature. CONSTITUTION:Liquid is sent into a fluid pipe 3, electric current is sent from a constant current source 4, 5 to sensors 1, 2 having a heat generating action and a temperature measurement action to heat them and the heater temperature is brought into a stable state. By opening an opening and closing valve 12, air is injected from an injection pipe 11. If mixed air with small heat conduction in the pipe 3 touches the sensors 1, 2, the temperature of the sensors 1, 2 becomes high. Thus, using the time T from the temperature rise of the sensor 1 to that of the downstream sensor 2 and the distance X between the sensors 1, 2, the velocity V and flowrate Q are calculated. When the viscosity is measured, the sensor 1 is replaced with an element having a temperature measurement function, and fluid temperature theta1 is measured. And the temperature theta2 of the sensor 2 of the heat generating element is measured and fluid viscosity is measured from the correlation between the temperature difference theta2-theta1 and the viscosity obtained in advance.

Title: Rod and optical scanning device using same
Inventor: ISHIKAWA TAKATOSHI
IPC: A63B53/10
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To enable resonance at a larger vibration frequency and to make the vibration of a tip part at the time of resonance larger by decreasing the thickness of the radial enclosure part of the rod from one end to the other end along the length. SOLUTION: A reflecting mirror 3 is fixed to one end of a torsion spring, whose other end is fixed to a base 1. The torsion spring is made thinner at the tip on the side of a reflecting mirror 3 than at the root. The rotating direction of a force applied to the torsion spring is inverted with the resonance frequency, and consequently the torsion spring has torsional resonance. The reflecting mirror 3 at the tip of the torsion spring has rotational vibration on the center axis of torsion of the torsion spring as the center of rotation. The torsion spring consists of a hollow part 2a and the enclosure part 2b, which is decreased in radial thickness B from the lengthwise base 1 side to the reflecting mirror 3. Consequently, the natural vibration frequency and the amplitude at the tip part at the time of resonance can be made large.

IPC: C01B13/11
Filed: 1999-12-14
Abstract: PROBLEM TO BE SOLVED: To prevent reduction in concentration of ozone formed during the operation of an ozonizer and to stabilize an operation efficiency. SOLUTION: An ozone generating facility which introduces a high-purity oxygen gas supplied from a liquid oxygen facility A into the ozonizer B and ozonizes the oxygen gas is combined with an air source C for mixing the oxygen gas supplied from the liquid oxygen facility with air (or nitrogen gas) and sending the mixed gas to the ozonizer. During the operation of the ozonizer, the oxygen gas is intermittently or continuously mixed with air or the nitrogen gas and sent to the ozonizer. Consequently, dissociation efficiency of oxygen molecule is raised, an ozone concentration is increased, a simultaneously formed nitrogen oxide is bonded to water attached to the surface of an electrode of an ozone generating tube to suppress the decomposition of ozone.  As a result, even if the ozonizer is continuously operated for many hours, reduction in concentration of ozone is prevented and stable operation performances can be exhibited.
