Title: Insulator
Inventor: OGAWA KAZUFUMI
IPC: C04B41/89
Filed: 1991-07-26
Abstract: PURPOSE:To provide a high withstand voltage insulator having a good water repellency, a good contamination resistance, and a high reliability with which dielectric breakdown is less likely to occur by forming a film of chemical adsorp tion monomolecular film including fluorine through siloxane coupling on the surface of an insulator of ceramic. CONSTITUTION:Hydrophilic OH-radicals 12 and SiCl4 on the surface of an insulator 11 are reacted for dehydrochlorination to fix the molecules to the surface through SiO coupling. Next, material including carbon fluoride radicals and chlorosilane radicals, that is CF3(CF2)7(CH2)2SiCl3, for example, is diluted and dissolved in nonaquaous solution, and the insulator 11 which is preprocessed as above is immersed in it. A monomolecular film 14 including fluorine is thus formed on the surface of the insulator at a film thickness of about 15Angstrom  chemically coupled with a lower-layer siloxane monomolecular film 13.

Title: Control method for etching solution
Inventor: HANIYU HIROHIKO
IPC: H01L21/306
Filed: 1984-09-07
Abstract: PURPOSE:To control stably an etching soln. with an electrical regenerating method by measuring the potential difference between an anode and the etching soln. in a regenerating cell and controlling the inter-pole current in accordance with the change in the electric resistance between the anode and anolyte. CONSTITUTION:The used etching soln. is transferred into a primary waste liquid storage tank 10, from which part is discarded as waste liquid and the balance is fed to a concn. adjusting tank 11. The soln. adjusted in specific gravity and hydrochloric acid concn. in said tank is returned to the regenerating cell 6. Constant current is passed to such etching soln. to convert the univalent copper ions to bivalent copper ions. Chlorine ions migrate from the catholyte side through an anion permeable membrane 9 to the anolyte side by which the regeneration of the etching soln. is effected. The electric resistance value exists between the anode 7 and the anolyte but the electric resistance is made constant at the point of the time when there are no more univalent copper ions. The current is controlled in such stage to maintain the electric resistance value corresponding to the compsn. meeting the etching conditions. The control is stabilized and the etching quality is improved by such method.

Title: Production of methyl methacrylate not containing diacetyl
Inventor: JIYANNFURANSOWA KUROWAJII
IPC: C07C67/48
Filed: 1995-06-30
Abstract: Prepn. of monomeric methyl methacrylate involves (a) reacting acetone cyanohydrin with H2SO4 or an oleum, to form methacrylamide, (b) reacting the methacrylamide, directly or after isolation, with methanol in presence of water, (c) sepg. the methyl methacrylate by distn. from the mixt. of H2SO4, (NH4)2SO4 and water, (d) eliminating unreacted methanol by liq.-liq. extn., and (e) distilling the washed methyl methacrylate in 2 stages: (e1) to eliminate residual traces of water, methanol and low-boiling impurities, and (e2) to separate pure methyl methacrylate (MMA) from high-boiling impurities. The novelty is that stage (e) is in presence of a non-aromatic 1,2-diamine which can react, under acid catalysis, with diacetyl present as impurity in the MMA to reduce its content; the diamine is added at a point such that the duration of contact with the MMA is sufficient to give considerable reaction with the diacetyl.

Title: Method and apparatus for producing photographic sensitive solution
Inventor: ICHIKAWA YASUNORI
IPC: B01F3/08
Filed: 1987-07-30
Abstract: PURPOSE:To enable feeding in the production of many kinds of sensitive solns. by using a motor-controlled flow rate controlling valve having a low change rate of flow rate to the valve lift and linear properties as each of flow rate controlling valves. CONSTITUTION:A motor-controlled flow rate controlling valve having a low change rate of flow rate to the valve lift and linear properties is used as each of flow rate controlling valves 12a, 12b. The flow rate controlling region of the valve from perfect close to full open is wide because the resistance is flow owing to the structure, and since the valve lift is made high to a change of flow rate and the shape of the valve head has such characteristics that the flow rate changes linearly to the valve lift, even a very small change of flow rate can be accurately controlled. Control can be rapidly and properly carried out by moving the valve head up and down with a servomotor, so a program of flow rate or electric potential is accurately and rapidly controlled and equipment and handling operation can be simplified even in case of feeding in the production of many kinds of sensitive solns.

Title: Production of glass material for optical member and optical member
Inventor: MURATA ATSUSHI
IPC: C03B11/08
Filed: 1988-07-28
Abstract: PURPOSE:To eliminate requirement for a mount or coating for shielding unnecessary rays by roughening a side surface of a cylindrical glass material. CONSTITUTION:Both end surfaces 3 on optical glass material are worked to mirror surfaces but a side surface 2 is roughened. Necessary surface roughnesses of the both end surfaces are <0.2 pref. <0.1mum expressed by the centerline average height. When the optical member to be prepd. is a convex lens, the end surfaces of the glass material are desired to be also convex. When the optical member is a concave lens, the end surfaces of the glass material are desired to be concave. Necessary surface roughness of the side surface 2 is >=0.2mum, pref. >=0.1mum expressed in terms of centerline average height. Namely, by constituting a glass material for an optical member of a material having roughened surfaces on the whole part other than surfaces functioning as optically effective surface and scattering incident rays incident to the outside of an effective diameter, unnecessary rays are shielded. Thus, mount and coating are unnecessary, so assembly of the optical member is facilitated.
