Title: Manufacture of ink jet head
Inventor: YONEZAWA KEIICHI
IPC: B41J2/135
Filed: 1995-02-27
Abstract: PURPOSE: To manufacture an ink jet head at low cost, which jets ink with a high precision. CONSTITUTION: A plurality of nozzle holes 6 are provided in the direction of a thickness of a passage substrate 3. The passage substrate is molded into two colors in such a manner that an inlet side 31 is made of a plastic material which can not be plated and a jetting side 32 is made of a plastic material which can be plated. The passage substrate 3 is treated with degreasing, etching, catalizer, accelerator, and treated with electroless plating and a plating layer 9 is formed only on a jetting section 6b. At this time, the inner face of the nozzle hole at an inlet section 6a is activated by the series of treatments and hydrophilic property is heightened, so that induction of an ink at the time of ink drop jetting is accelerated.  It is cleaned after completion of plating and a water-repellent material layer 10 is formed on the surface of the plating layer 9 by fluoro-electrodeposition coating. Thus, the water-repellent property of the nozzle hole at the jetting side 32 is heightened, so that the ink can be easily dissociated at the time of ink drop jetting and straight-ahead property of ink drops is heightened.

IPC: H01L21/304
Filed: 1991-02-12
Abstract: PURPOSE:To enable an Si substrate surface to be purified under conditions without any high-temperature substrate heating or surface damage and space- selectively by supplying a raw material gas including Si while emitting vacuum ultraviolet rays or soft X rays to a region where a surface of the Si substrate which is coated by an oxide film is to be purified.

Title: Method for measuring ascorbic acid
Inventor: MATSUMOTO KINYA
IPC: G01N33/82
Filed: 1988-02-22
Abstract: PURPOSE:To prevent errors by unequalcolors and to facilitate decision by using a tetrazolium compd. as a color forming component and bringing the same into reaction with ascorbic acid under such conditions under which the pH at the time of reaction changes from neutral to alkalinity. CONSTITUTION:The tetrazolium compd. is used as the color forming component and is brought into reaction with the ascorbic acid AS at the neutral to alkaline pH at the time of the reaction to facilitate decision in a low concn. region from the coloration corresponding to the content of the AS in the sample. The generated dye is insoluble and there is no false recognition of the decision by elution of the dye from a test paper piece. The tetrazolium compd. to be used is not particularly limited if said compd. is the tetrazolium compd. which is reduced to color by reaction with the AS and the generated dye is insoluble. More preferably, 3-(p-iodophenyl)-2-(p-nitrophenyl)-5-phenyl-2H tetrazolium chloride (INT), etc., are used. The error by the unequal colors is thus prevented and the decision is facilitated.

Abstract: PURPOSE:To obtain a protective film, the surface thereof is flat and parasitic capacity thereof is small, by coating a section except the bonding pad forming section of a Si substrate with a mask material, removing the surface up to predetermined depth and shaping a SiO2 film to the removed section. CONSTITUTION:The Si3N43 coating the section except the section where the formation of a bonding pad is prearranged is shaped to a SiO2 thin-film 2 on the P type Si substrate 1, and the Si substrate 1 is shaved off only by approximately 0.5mu through etching by the mixed liquid of nitric acid and fluoric acid. A P type impurity is diffused and surface concentration is increased as necessary, and the SiO24 with approximately 1mu thickness is formed through wet oxidation. When the Si3N43 is removed, the substrate with an approximately uniform surface with no difference in stages is obtained, and the electrode of the bonding pad, etc. is shaped onto the thick film 4. Accordingly to this constitution, thermal oxidation may be only once, a change corresponding to impurity concentration is reduced, a bird-head is relaxed, disconnection is decreased, and the SiO2 film 4 can be thickened, thus diminishing the parasitic capacity of the bonding pad and wiring.
