Title: Treating apparatus for exhaust gas of vacuum pump
Inventor: YAMAMOTO SUGURU
IPC: B01D53/77
Filed: 1978-01-17
Abstract: PURPOSE: To remove efficiently a small quantity of harmful gas without disturbing exhausting performance of a vacuum pump, by connectisng the exhaust port of the vacuum pump through the empty first tank with the second tank contg. gas-absorbing water at the lower part.  
     CONSTITUTION: Exhaust gas contg. HF, HCl produced in sputter-etching of fluoroolefin polymer is discharged by a vacuum pump P. In this case, the exhaust gas is led by the back press. of the pump P through a reverse U-shaped pipe 8, a diffuser 7 to the second tank 3, there it is diffused into a gas absorbing soln. 5 (e.g., aq. solution of NaOH), so as to make the absorbing soln. 5 absorb the harmful gases, the treated gas being discharged through an exhaust pipe 9. In this process, becuase the quantity of the harmful gas is small, the service life of the absorbing soln. is long, and both running and equipment costs are low.

Filed: 1987-01-12
Abstract: PURPOSE:To prevent an image from flowing out and to suppress defective cleaning usefully with the small consumption of toner by sticking a grinding developer to an image area of an image carrier only when an original has many white parts. CONSTITUTION:A comparator 24 converts a density level signal obtained from an image processing circuit 22 into a vinary signal and stores the binary signal for one line in a memory 26 through a shift register 25 and a CPU 27. The CPU 27 adds the binary signal stored in the memory 26 every subscanning, and when the storage capacity of white level signals exceeds a fixed value, outputs an operation signal at the time of forming a non-image. A laser driving circuit 23 radiates a laser beam with a prescribed width to an image area A of a photosensitive drum 12 in the subscanning direction along the main scanning direction. Toner is stuck to the portion irradiated by the beam and the toner is used for grinding the image area A by means of a cleaner. Consequently, the image flow in the image area A can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To reduce a connection resistance value at electrical connection and to surely perform electrical connection by coating a metal having a thickness of a specific range on a core material of resin. SOLUTION: A film-like binding layer containing a conductive particle 7 is attached over the wiring pattern of a printed circuit board. A conductive particle 7 is formed in a plated particle of resin, whereby the periphery of a plastic resin particle 40 as a core material is coated with a metal layer 70 that an Ni metal layer 50 and an Au plating layer 60 are laminated. The plated particle of resin is to have a diameter (d) of 3-5 μm, the particle diameter becomes uniform, and the connection reliability is enhanced. The number of conductive particles 7 sandwiched between the wiring pattern of the printed circuit board, and the projection electrode of an IC is determined by the area to sandwich them. To reduce connection resistance, the thickness of the metal layer 70 is made thicker to have a 1,000-3,000 Å thickness.  The resistance value is reduced, and the resilient force of the plastic resin particle 40 is held. The Au plating layer 60 is set at a thickness of 400-1,000 Å, and reduction in resistance values and a coat increase are suppressed.

Title: Cold-cathode lamp
Inventor: MINAMIMURA YUICHI
IPC: H01J61/20
Filed: 1989-01-13
Abstract: PURPOSE:To prevent deterioration in brightness at a low temperature and occurrence of mercury spot by limiting an amount of mercury to a specific value. CONSTITUTION:In a cold-cathode lamp consisting of an electrode with a mercury getter and a valve, an amount of mercury is limited to 12 to 15mg. As the amount of sealed mercury increases in a cold-cathode discharge tube, mercury spots occurring on a tube wall increases while argon discharge is likely to occur when sealed mercury short. Therefore, by regulating the lower limit of the mercury amount to 12mg, mercury will not run short within a predetermined service life even if mercury decreases in amount due to low temperature operation, and by regulating the upper limit of the mercury amount to 15mg, occurrence of mercury spots can be suppressed. This prevents occurrence of mercury spots and deterioration in brightness due to argon discharge at low temperature.

Abstract: PURPOSE:To permit display of 4 colors with high color purity by combining liquid crystal layers formed by dissolving dichroic dyes into liquid crystals and subjecting the liquid crystals to a twist orientation and color polarizers to constitute 2 layers of liquid crystal display elements. CONSTITUTION:This display device makes 4-color display by the two liquid crystal layers 2, 3, the neutral polarizer 1 and the color polarizer 4. Both the liquid crystal layers 2, 3 are so oriented as to twist approximately 90 deg.. The liquid crystal which is prepd. by dissolving the dye into the liquid crystal and is known as 'guest-host liquid crystal' is used for said layers. The neutral polarizer 1 is formed by adsorbing the dichroic dye such as iodine which absorbs light over the entire visible light region on a uniaxially stretched PVA film. The color polarizer 4 is formed by adsorbing the dichroic dye which absorbs light of only the specific wavelength on the similar film. The 4-color is realized with a relatively smaller number of lamination of 2 layers by ingeniously combining the orienting directions of such color liquid crystal layers and the absorption axis directions of the polarizers.
