Title: Dynamic semiconductor storage device
Inventor: SAKAGAMI MASAHIKO
IPC: G11C11/401
Filed: 1990-11-20
Abstract: PURPOSE:To clear or preset data at a high speed by connecting a bit line to potential which is defferent from the potential of precharge after one word line among plural word lines is selected and before a sense amplifier acts when the precharge of the bit lines is finished. CONSTITUTION:After the finish of the precharge of the bit lines BL and NBL, a reset signal phiR is switched to 'H' after any word line WL11 or the like is selected and before the sense amplifier SA acts. As the result, a transistor Q18 is turned on and the potential of the bit line BL is forcibly changed to reference potential Vss so as to make it different from the potential of the precharge. Due to that, the whole data of identical row-address can be cleared by one cycle and the data of whole memory cells A11, A12 or the like can be cleared by the cycle corresponding to the number of row-address. Thus, the whole memory cells A11, A12 or the like is cleared and preset at a high speed.

Title: Controller of air conditioner with refrigerant heater
Inventor: MORISHIGE ARIKICHI
IPC: F25B13/00
Filed: 1990-11-22
Abstract: PURPOSE:To reduce the noise of refrigerant at the completion time of refrigerant draining by providing a device which sequentially makes a second two-way valve ON, a first two-way valve ON and then the second two-way valve OFF at particular time intervals after a compressor is brought in operation to start heating. CONSTITUTION:A controller 19 controls a compressor relay 1a, a bypass two- way valve relay 8a and a two-valve relay 11a. When a compressor 1 is brought in operation, refrigerant draining is started (a two-way valve 11 is turned OFF). When a time period T1 elapses, a bypass two-way valve 8 is turned ON and when a time period T2 passes after that, a two-way valve 11 is turned ON, thus refrigerant draining is completed. When a time period T3 elapses, the bypass two-way valve 8 is tuned OFF and normal heating mode takes place. Since the bypass two-way valve 8 is turned ON immediately before the completion of refrigerant draining as mentioned above, the pressure difference across the two-way valve 11 decreases. As a result, the flow noise of refrigerant generated at the moment of the completion of refrigerant draining can be controlled at a low level.

Title: Level measuring method for molten tin in float bath
Inventor: OKAMURA SHINICHI
IPC: C03B18/18
Filed: 1992-11-27
Abstract: PURPOSE:To allow automatic level measurement of molten tin in a float bath by irradiating the surface of molten tin with a laser spot light, picking up the light scattered at the irradiated part in order to determine displacement, and then expressing the displacement thus determined in terms of tin level. CONSTITUTION:Molten glass 1 is introduced from a furnace onto molten tin 3 in a floating bath 2 to be shaped. A laser light source 5 oscillating infrared rays and a CCD two-dimensional camera 6 mounting a BPF for cutting unnecessary lights at the tip thereof are disposed, while being housed in one box 7, at a monitor window 4. Cooling air or water is circulated through the box 7 in order to restrain temperature rise. Horizontal surface of molten tin is then irradiated with a spot light from the light source 5 at a predetermined angle and scattering light is picked up by means of the camera 6 installed at a predetermined angle with respect to the horizontal surface. Since the camera 6 picks up not the displacement but the length of the level of molten tin, it is expressed in terms of the amount of displacement thus determining the amount of displacement of actual level.

Title: Fuel pressure pump
Inventor: OTAKI MIZUO
IPC: F04B53/00
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent fuel leaks from sealing portions about driveshafts reliably, and notify drivers about degradations of the sealing portions at an early stage. SOLUTION: A main seal lip 33 and a subsidiary seal lip 34 all fitted tight on the periphery of a driveshaft 14 are spaced away from each other in the axial direction of the driveshaft 14. That face of the main seal lip 33 which is exposed to an operating chamber 11 receives fuel pressure that a low-pressure regulator 50 feeds into the operating chamber 11. A space 35 between both seal lips 33 and 34 is designed to have an internal pressure equal to the atmospheric pressure. A pressure switch 41 operates or becomes ON when the internal pressure of the space 35 reaches a preset value or above, and an alarm lamp 42 goes on when the pressure switch 41 works. Both seal lips 33 and 34 provide a double advantage in preventing fuel leaks about the driveshaft 14, and the alarm lamp 42 notifies drivers about degradations of the main seal lip 33 by lighting.

Abstract: PURPOSE:To volatilize the impurities contained in the sample during the ashing stage and to enhance reliability of the result of analysis by adding a rhodium nitrate aq. soln. to a sample and burning this mixture to ashes and thereafter atomizing them. CONSTITUTION:A sample is introduced into a graphite tube 1 from a sample introducing port 1b and a rhodium nitrate soln. is added. Thereby the two kinds of liquid are retained in a sample containing part. In this state, the tube 1 is raised in temp. to dry water contained in the sample and the rhodium nitrate soln. Successively the tube 1 is raised in temp. and these are burnt to ashes. Thereby tellurium contained in the sample is compounded with rhodium nitrate. Thus, the compound which is made stable until about 1,000 deg.C and is allow in volatility is formed and volatilization at ashing temp. is inhibited. In such stage that ashing has been finished, when the tube 1 is raised in temp. until about 1,500 deg.C suitable for analysis of tellurium, tellurium existing as stable substance in the ashing state is thermally cracked and atomized. Tellurium is atomized at concn. substantially contained in the sample and absorption is caused thereby.
