Title: Chromic acid sealing liquid composition
Inventor: DEGUCHI TAKENORI
IPC: C23C22/83
Filed: 1980-04-23
Abstract: PURPOSE:To impart high corrosion resistance without dissolving a phosphate film formed on a steel plate by adding a zinc ion donor in an amount so as to adjust a pH of a chromic acid sealing liquid after a zinc phosphate painting pretreatment process of a zinc hot dipping steel plate to a specified value. CONSTITUTION:As a chromic acid sealing liquid of a colored and a colored zinc steel plates, a zinc ion donor selected from a metal zinc, zinc hydroxyde, zinc oxide and zinc phosphate is added to an aqueous solution containing 1-30g/l of anhydrous chromic acid to adjust a pH thereof to 3-7. Herein, if CrO exceeds the upper limit, close adhesiveness of an undercoating paint is obstructed by oxidizing action of residual hexavalent Cr or the like. Further, if the pH value is below 3, said close adhesiveness is controlled by a H<+> concn. and the dissolution of a phosphate film is increased and, if the pH value is above 7, it is not preferable from a standpoint of moisture proofness of a coating.

Title: Growth of nitride semiconductor
Inventor: OZAKI NORIYA
IPC: H01L21/205
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a process for growing a nitride semiconductor having crystallinity which is satisfactory for it to become a substrate. SOLUTION: The process comprises the steps of a first step of selectively forming a protective film 10 made of a material different front that of a nitride semiconductor 3 on the surface of a first substrate 1, a second step of forming within the film 10 a multilayered film 4 by growing at least two nitride semiconductor layers the compositions of which are different from each other, and a third step of growing on a film 4 a nitride semiconductor layer that will become a second substrate 5. For selective growing, the film 4 to be formed at a window portion tends easily to provide a plagiarized nitride semiconductor surface in the second step. Therefore, when the nitride semiconductor, which is to become the substrate 5, is grown on the film 4, a planarized substrate having good drystallinity can be fabricated.

Title: Shaft sealing apparatus for pump
Inventor: MOCHIZUKI SHIGERU
IPC: F16J15/18
Filed: 1981-04-10
Abstract: PURPOSE:To obtain a shaft sealing apparatus including a gap controlling means, which can work satisfactorily for all values of internal pressure in an inner space in a protective pipe and is capable of feeding an optimal amount of water for lubricating bearings and for lubricating gland packings in a stable manner for a long time. CONSTITUTION:In such a mode of use that the value of pressure in a second inner chamber 32 of a protective pipe 27 is higher than the atmospheric pressure, a packing box 24 is moved away from an orifice plate 33 by manipulating a control means 36 for a gap 34, so that the capacity of the gap 34 for controlling the flow rate of pressure water is increased. On the other hand, in such a mode of use that the value of pressure in the second inner chamber 32 is lower than the atmospheric pressure, the packing box 24 is moved toward the orifice plate 33, so that the capacity of the gap 34 is decreased. By thus controlling the gap 34, distribution of pressure water to a lower bearing (not shown) and to the sliding portion between gland packings 25 and a sleeve 23 is controlled to be optimal under any mode of use of a pump.

Filed: 1989-03-08
Abstract: PURPOSE:To improve printing speed without failure in freedom of a function for printing in an arbitrary size by adding a function for permanently storing by previously developing as a bit map font of a predetermined size. CONSTITUTION:Whether data received by an input unit 1 is a copy command or not is judged. If it is the command, whether the presently selected font is a vector font or not is judged.

Then, the developed vector font is stored as a bit map font to be able to be identified in a RAM 5. On the other hand, if it is not the vector font, the present font is stored in the RAM 5 to be able to be identified. If a copying is once conducted, a character of specific size and format is automatically read by the bit map font of the RAM 5.
