Title: Method for working discharge nozzle of liquid jet recording head and manufacture for liquid jet recording head
Inventor: KOIDE JUN
IPC: B41J2/135
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for working discharge nozzles of a liquid jet recording head whereby an orifice plate and a mask plate can be efficiently and easily aligned relatively when the orifice plate is brought in tight contact with the mask plate and laser beams are radiated from the side of the mask plate to process discharge nozzles. SOLUTION: A dielectric total reflection mirror coating layer vapor deposited on an opposite face of a colorless transparent quartz substrate where an ultraviolet laser light enters is aligned with a discharge port and removed by etching, thereby forming a pattern 11. A mask plate 1 with the pattern 11 is brought in tight contact with an orifice plate 2. The pattern 11 of the mask plate 1 is observed by passing a visible light via the mask plate 1 by a projection lens 102 and an image pickup element 13. A liquid channel of a recording head body 3 is observed by passing a visible light via the orifice plate 2 of a transparent resin. A working position of the orifice plate 2 and the pattern 11 of the mask plate 1 are thus aligned.

Title: Rotor heating device
Inventor: KOJIMA SHIYUUHEI
IPC: F01D25/10
Filed: 1982-10-20
Abstract: PURPOSE:To reduce energy consumption of a rotor heating device for high speed balancing of a rotor by providing a heating box to house a rotor in a vacuum chamber. CONSTITUTION:A heating box 12 for housing a drum part of a rotor 13 is provided in a vacuum chamber 11. The rotor 13 is connected to a driving device 16 by means of a liaison 15. Further, hot air is supplied from hot air generation devices 17, 18 into the heating box 12. At the time of heating a rotor 13, hot air is supplied while rotating the rotor 13 at low speed and the rotor 13 is heated until it exceeds the transition temperature. Subsequently, the rotor is put in high speed rotation for high speed balancing. Since heating is thus performed while rotating the rotor at low speed, windage loss due to high speed rotation can be reduced.

IPC: G03G15/01
Filed: 1986-08-04
Abstract: PURPOSE:To reduce the consumption of each color toner by applying a bias electric field, which prevents the surface staining of an image, to a developing roll when a developer is supplied to a developing device. CONSTITUTION:In a recorder where developers in respective colors are selectively supplied to one developing device 5, the electric field which attracts the toner to the developing device 5 is allowed to act on the developing device 5 when the developer in any color is supplied to the developing device 5. This electric field acts by the application of the bias voltage which prevents the surface staining for recording, and further, an electrifying charger for a photosensitive body 3 is turned off at this time. Thus, the consumption of each color toner is reduced.

Abstract: PURPOSE:To reduce the influence of phase noise included in the output of a numerical control oscillator to the output of a transmitter by setting a signal from a fixed oscillator with less phase noise to be a main frequency and setting a signal from a numerical control oscillator with much phase noise to be a subordinate frequency.

Filed: 1989-07-13
Abstract: PURPOSE:To shorten the cooling time of a wafer without generating a warpage in the wafer by a method wherein the wafer is fixed and cooled on a rotating chuck provided with a heating means, which is heated with an atmosphere in an annealing furnace, and a rotational speed variable means. CONSTITUTION:When a high-temperature wafer 5 taken out in the atmosphere is rotated, a heat dissipation from the surface of the wafer 5 is accelerated. Therefore the cooling time of the wafer can be shortened. In this case, if a stand (a quartz chuck) 17 for placing the above high-temperature wafer 5 is located in the vicinities of normal temperatures, for example, a warpage is sometime generated in the wafer 5 because the temperature difference between the stand 17 and the wafer 5 is large. There, after the high-temperature wafer 5 taken out from an annealing chamber (a quartz chamber) 10 is set on the placing stand 17 heated previously utilizing high-temperature gas in the chamber 10, the wafer 5 is rotated along with the stand 17 to contrive to cool the wafer 5. Thereby, the wafer can be cooled in a short time without generating the warpage in the wafer 5.

Title: Multistage constant pressure balanced power generating device
Inventor: KUBOYAMA NOBUYOSHI
IPC: F24J3/00
Filed: 1986-08-06
Abstract: PURPOSE:To save the energy consumption for an overall system by disposing a constant pressure balanced rotary mechanism in a suitable closed space having a projection as an assembly making up a space, and disposing multiple spaces internally in multi- stages to make up a multicellular structure. CONSTITUTION:When a rotary body 4 is rotated by the action of a driving Source 5, fluid is drawn in from an inlet 2. As a reduced pressure balanced heating action takes place in a reduced pressure balanced heating mechanism A of a pressure regulating chamber 12, the fluid temperature is raised to a desired temperature. Since a driven rotary body 8 opposing the rotary body 4 is rotated in the same direction because of the viscosity of the fluid, a rotary output can be obtained from a rotary shaft 9 via a transmission 20. Then, by operating a power generator 21, a desired electric energy can be retrieved. As the rotary action of the rotary body 4 is performed in the pressure regulating chamber 12, the pressure reduction effect is enhanced on the leading side of the rotary body 4. However, on the trailing side, there is a pressure increasing action. Therefore, a spinning flow which has driven the driven rotary body 8 helps the rotation of the rotary body 4 from its trailing side because of the backlash effect, allowing an efficient operation with an economical energy.
