Title: Production of electrophotographic photoreceptor
Inventor: TAWARA EIJI
IPC: G03G5/05
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To easily remove air bubbles in coating liquid and to prevent a defect from occurring in a photoreceptive layer by holding the coating liquid under pressurization and dissolving the air bubbles included in the liquid in the middle of making overflowing coating liquid circulate to a coating tank. SOLUTION: An evacuating and deaerating tank 3 is charged with the coating liquid from a coating liquid charge port 8. Next, valves 9 and 10 are closed and a vacuum pump 4 is actuated, so that the tank 3 is evacuated and the air bubbles and the dissolved gas in the coating liquid are removed. At such a time, the pressure in the tank is made much higher than the saturated vapor pressure of the coating liquid so as not to change the composition of the coating liquid by the evaporation of a solvent in the coating liquid. When deaeration is finished, the pump 4 is stopped and the valves 9 and 10 are opened to restore the pressure in the tank to atmospheric pressure.  That is, instead of separating the air bubbles in the coating liquid from the coating liquid, the coating liquid is held under the pressurization so as to dissolve the air bubbles in the coating liquid, whereby the air bubbles in the coating liquid are removed.

Filed: 1989-06-12
Abstract: PURPOSE:To facilitate formation of a thin film of accurately decided thickness by removing a part of a lower single-crystal silicon wafer until a silicon oxide or silicon nitride thin film is exposed. CONSTITUTION:In etching a part of a lower single-crystal silicon wafer 3 as substrate, a silicon oxide or silicon nitride thin film 2 as an etching stopping layer is formed under a single-crystal silicon thin film 1. Therefore, even if the concentration or the temperature of etching liquid is uneven, the etching stops when reaching the silicon oxide or silicon nitride layer 2 without applying bias voltage. Thereby a single-crystal silicon thin film of accurately decided thickness can be made easily.

Title: Iron-zinc alloy plated steel material
Inventor: AZUMA MITSUO
IPC: C25D5/10
Filed: 1981-09-24
Abstract: PURPOSE:To obtain steel materials having particularly high rust resistance, corrosion resistance, chemical convertibility, paintability, workability and weldability by forming the iron-zinc alloy plating on the steel materials for automobiles, household electrical appliances, etc. of two layers of respectively different alloy structures. CONSTITUTION:Steel materials having an iron-zinc solid soln. alloy layer of 0.5-7g/m<2> thickness and <=35wt% zinc content of an upper layer (surface) and an iron-zinc intermetallic compd. alloy layer of 5-25g/m<2> thickness consisting of >=1 kind among delta1, GAMMA, zeta, phases on a lower layer. These plating layers are obtained by plating the steel materials first with an insoluble anode at 60-200A/dm<2> current density and 40-80 deg.C bath temp. by using a sulfate bath of 0.4-0.9 Zn<++>/Fe<++> weight ratio in the bath, 100g/l total and within solubility limit on sulfate concn. of both metals, and 0.8-2.3pH. If the thickness of the layers is below the lower limit, corrosion resistance is insufficient, and if in excess of the upper limit, productivity, workability and weldability are degraded. Thereafter, the steel materials are plated under the similar conditions at 0.02-0.15 Zn<++>/Fe<++> weight ratio. Since the thickness of the layers is thin, formability and workability are good. Chemical convertibility is good at above the lower limit, and the generation of defects in the paint film is small.

IPC: B29C48/76
Filed: 1985-07-08
Abstract: PURPOSE:To provide a prevention device of venting-up in a molding machine wherein cleaning at a vent port is made unnecessary, by fitting a heating device so that a rotating direction of a screw becomes a high temperature. CONSTITUTION:A heating device 7 is fitted to a part A so that the temperature of the rotary direction side A of a screw 3 becomes higher than that of the opposite side B.

Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of surface staining and to surely improve image quality by solidifying a surface layer part being the thin layer of liquid type developer formed on a developer carrier in a film state. SOLUTION: The thin layer is formed of the liquid type developer 91 applied by a coating roller 23 on the surface of a developing belt 26.

Title: Distribution type fuel injection pump
Inventor: TANAKA BUNRO
IPC: F02M41/12
Filed: 1985-07-10
Abstract: PURPOSE:To prevent breakage of a face cam and a cam roller caused by fatigue and to cope with high speed engine operation and high pressure fuel injection, by regulating by a stopper that a cam profile of the face cam separates from the cam roller. CONSTITUTION:Even if a plunger 8 and a face cam 9 jumps so that they separate from a cam roller 10, a stopper 49 abuts against a distribution head 43 to prevent breakage caused by close contact of a plunger spring 48. Since the stopper 49 is attached to a pressure plate 45 through an impact absorbing member 50, it prevents the stopper 49 from being broken by impact and reduces impact force caused in the plunger 8 and the face cam 9 and also prevents pitching which permits the face cam to be separated again from the cam roller 1. Thus, it is possible to cope with high speed engine operation and high pressure fuel injection.
