Title: Copper coating method
Inventor: IKEGAMI TAKATOSHI
IPC: C23C18/40
Filed: 1979-08-22
Abstract: PURPOSE: To form copper coating layers lowering the rate of mixing a reducing agent into the resulting powder by adding crystals of copper salts to a slurry contg. metal particles to be coated with copper and a copper ion reducing agent in an amount exceeding the solubility to the amount of water in the slurry.  
     CONSTITUTION: Metal particles such as lead powder are added to a fixed amount of water, and a surfactant rendering the particles hydrophilic may be added. To this aqueous metal particle suspension is added a reducing agent made of metal such as zinc or iron having ionization tendency larger than that of copper, and by mechanical agitation a slurry consisting of the particles and the reducing agent is prepared. To this slurry are then added crystals of copper salts such as copper sulfate in an amount exceeding the solubility to the amount of water in the slurry. After the reaction, sieving, dehydration, washing and drying are carried out by usual methods to manufacture copper coated metal particles having the desired copper content. By this method the copper content of the copper coated particles can be controlled according to the purpose, and the amount of the reducing agent used can be decreased as compared to a conventional method.

Abstract: PURPOSE:To reduce the level difference of a 2P (light curing resin) layer by using a glass fiber tube at the time of curing the 2P formed on prescribed inner and outer peripheral end parts and obliquely projecting light. CONSTITUTION:The 2P existing between a stamper 15 and a transparent base 13 is expanded up to a prescribed area by the tare of the base 13 and the rotation of the stamper 15 and light is projected from the glass fiber tube 12 at a position with a fixed width from the inner and outer peripheries of the base 13 to cure the end part of the 2P and fix its position. At that time, light flux from the glass fiber tube 12 is obliquely projected from the center part to the outer and inner peripheral parts, and after slightly opening between the tube 12 and the base 13, and the opening is radiated to the whole by the light to completely cure the 2P. Since the curing at the end part of the 2P is restricted only to an extremely narrow range and the whole 2P is simultaneously contracted by stress due to the contraction of the center part, the base almost removing the level difference of the 2P layer can be obtained.

Filed: 1981-07-10
Abstract: PURPOSE:To prevent occurrence of collision and sliding contact between a balance disk and a fixed wall at the time of starting, by providing valve means which operate to communicate a high-pressure chamber and a pressure chamber in the balance disk with each other when the difference of pressure in the high- pressure chamber and that in the pressure chamber in the balance disk is great. CONSTITUTION:A plurality of valve means 10 disposed around the circumference of a balance disk 11 operate to communicate a pressure chamber 7 in the blance disk 11 and a pressure chamber 8 at the back of a vane wheel which constitutes a high-pressure chamber with each other when the difference of pressure in the chamber 7 and that in the chamber 8 is great. In case that the pressure drop across a clearance 5 is great, for instance, at the time of starting, a valve body 13 is disengaged from a small hole 16 by the differential pressure between the two chambers 7 and 8 against the force of a compression spring 12, while during ordinary operation, the force of the compression spring 12 overcomes the differential pressure, so that the small hole 16 is closed by the valve body 13. Further, since pressure in a pressure chamber 9 is substantially equal to that in the chamber 7 at the time of starting, it is enabled to avoid contact between the balance disk 7 and a fixed wall 4.

Filed: 1991-05-13
Abstract: PURPOSE:To enable dot shaped exposure high in density with no minute shaped fluorescent material required by enabling electrons to be emitted selectively from fluorescent material coated in a belt shape and a number of electron sources. CONSTITUTION:When specified voltage is applied to the exciting electrode 17 of a point electron source 7, field emission takes place at a peak electrode 16, so that electrons are thereby emitted out of the source 7. And the electrons emitted from the source 7 are accelerated so as to be hit against an electrode 3 with positive voltage applied to the transparent anode electrode 3. In this case, the electrons emitted from the source 7 stimulates fluorescent material 4 coated over the electrode 3 so as to make it luminous, so that light emitted is outputted through the openings bored in the electrode 3, a glass substrate 2 and a glaring mask 13. In this case, when the voltage is changed, which is to be applied to each extracting electrode 17 of respective sources 7, based on image information to be recorded, the line of emission points can thereby be formed in response to image information. By this constitution, no minute shaped fluorescent material is required, dot shaped exposure high in density can thereby be obtained.
