IPC: B08B3/08
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To perform precision cleaning irrespective of the shape or the like of a material to be cleaned and to prevent liquid accumulated and remaining soil from occurring by immersing the material in a cleaning liquid consisting of saturated hydrocarbon having carbon atoms of a specified value and pulling up the material at a speed lower than the falling speed of the cleaning liquid stuck on it. SOLUTION: In a cleaning tank 2 filled with isononane or the like which is hydrocarbon as a cleaning liquid 1, an optical lens is immersed in the cleaning liquid as a material 3 to be cleaned, and it is gradually pulled up and cleaned by using a pulse motor. Here the cleaning liquid consists of saturated hydrocarbon of 8-12 carbon atoms, and the material 3 is pulled up at a speed lower than the falling speed of the liquid stuck on the material 3 from the interface of the liquid. Besides, the pulling up speed of the material 3 after immersion is about <=70mm/s. As the liquid consisting of saturated hydrocarbon having 8-12 carbon atoms, hydrocarbon whose 95% recovered temperature is within 20 deg.C above the initial boiling point(1BP) and whose 99% recovered temperature is within 60 deg.C above 1BP is preferably used.

Title: Zinc-bromine electrolyte circulation type secondary battery
Inventor: JINNAI KENICHIRO
IPC: H01M12/08
Filed: 1988-08-12
Abstract: PURPOSE:To facilitate circulation without changing the circulating direction of electrolyte by disposing a positive and negative cell chambers vertically, thereby enabling the electrolyte to flow in each cell horizontally. CONSTITUTION:Positive and negative cell chambers 2, 3 are superposed vertically so that an electrolyte can flow in each cell chamber horizontally. In this case, the air in the chambers can be pushed out to tanks 9, 10 easily irrespect of the circulating direction upon pouring-in of electrolyte. Since the electrolyte flows in the chambers 2, 3 horizontally, it can move evenly from the inlet to the outlet of chambers even if a reaction product with a large specific gravity is generated so that it is not necessary to limit the circulating direction at normal operation performing charging/dischaging. It is thus not necessary to change the circulating direction both at normal operation performing charging/ discharging as well as at pouring-in of electrolyte.

IPC: B29C45/34
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To obtain a gas venting method of a chill vent which prevents the flow-out of molten material and holds air-tightness in a cavity by supplying cooling liquid in a gas venting groove of the chill vent. SOLUTION: Filling of the molten metal is progressed and at the same time of almost exhausting the gas in the cavity, the molten metal reaches a communicating hole. A molten metal sensible sensor 15 arranged at the communicating hole transmits a molten metal detected signal to PC 26 and pressurized foaming agent is supplied into a foaming agent discharging pin 21 through a foaming agent supplying passage 23 and a penetrating passage 22 by transferring a foaming agent supplying signal to a foaming agent supplying pump 16 through the PC 26. The foaming agent reaching the foaming agent discharging pin 21 is fed to a spouting hole at the tip part 25 through an outer peripheral groove, passage and penetrating hole and spouted into the gas venting groove 20 from a clearance.  Since the foaming agent directly cools the molten metal invaded from the upstream side of the gas venting groove 20, the tip part of the molten metal is solidified in the gas venting groove 20.

Title: Video information display system
Inventor: KADOWAKI SATORU
IPC: G09F19/12
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To reduce maintenance cost and running cost by controlling a radiating device by which video information is radiated on a hologram screen that is attached to a transparent member from a central controller which is connected through a communication line. SOLUTION: A sensor 13 detects that an observer 8 enters, sends a signal to a radiation controller 14 and a radiating device 12 is started. Because a hologram screen 11 is transparent and video information is suddenly shown on a transparent member 10 on which nothing exists to the observer 8, a high eye catch effect can be acquired. Because the operation of the device 12 is stopped when the observer 8 leaves and he separates from the angle of visibility of the sensor 13, it is possible to save power consumption of this device, to reduce running cost and to extend the life of the device. A central controller or a relaying device performs the correction of the trapezoidal distortion of video information to be displayed and the correction of color tones and the central controller collectively performs the distribution of display information, the management of the irradiating device and the collection of maintenance information for each part through a communication line to save manpower.

The driving mechanism transforms the rotation to an oscillation movement of the elastic blade 53 via a rotary cam plate 75 frictionally engaged with the driving gear 74. Further, the driving mechanism transforms the oscillation movement of the elastic blade to an oscillation movement of the lock lever 52. Since each of the driving parts can be driven by the common driving mechanism, the apparatus can be small and compact in constitution.
