Title: Simple concentration control method for surface treating agent
Inventor: ISAKA AKIRA
IPC: G01N31/00
Filed: 1992-04-02
Abstract: PURPOSE:To control concentration easily by adding an indicator after two solutions are prepared for the upper limit and the lower limit of solution control normality, and identifying whether or not it is within range of the normality after treating solution to be measured is added to this. CONSTITUTION:Solution in the lower limit normality of concentration control width of solution to be measured is prepared beforehand. For example, when the lower limit of the solution to be measured is acid or alkali of 0.2 normal in the normality, the acid or the alkali of 0.1 normal may be prepared twice a gathering quantity. An indicator is added beforehand to this solution. Next, treating solution is added by a constant quantity to this solution. With this, identification can be made immediately on whether the treating solution is in the lower limit or above control width. Next, solution in the normality of the upper limit value is prepared similarly. In the same way as the lower limit value is measured, the normality and a quantity of the prepared solution may be adjusted or regulated by the normality of the acid or the alkali. In this way, the upper limit and the lower limit of control width of the treating solution can be measured instantly.

IPC: B22D21/04
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To reduce the development of fine bulged parts and to improve the surface smoothness by regulating the cast block thickness of a blank of aluminum base metallic material of the value not larger than a specified value and applying grinding and non-magnetic preparation treatment. SOLUTION: The thickness of a cast block as the blank constituting the substrate for magnetic disk is regulated to <=400 mm and the substrate having about 0.5-1.5 mm thickness is produced. The blank shearing a belt-like thin plate formed by rolling the cast block of the aluminum base metal into the disk substrate shape, is used and a chamferring process for grinding the shorn corner parts is applied. Successively, after applying process for grinding to the flat surface, a non-magnetic preparation treatment process of plating, etc., a polishing process for specular-polishing and texture process, the substrate for magnetic disk is produced through the non-magnetic substrate layer forming process if necessary. The grinding process is desirable to grind the substrate surface with a grinding stone having about #3000-6000.

Title: Production of hologram
Inventor: TANIGUCHI NAOSATO
IPC: G03H1/02
Filed: 1987-05-25
Abstract: PURPOSE:To uniformize quality and to prevent exfoliation of a hologram layer even under the conditions of a high temp. and high humidity or high-temp.-low temp. cycles by preventing the clouding and cracking of the hologram obtd. by subjecting a recording carrier to photoirradiation from both faces prior to removing of a halogen-contg. material which is a sensitizing agent. CONSTITUTION:The recording carrier is subjected to the photoirradiation from both faces to partly crosslink or strengthen the entire surface of the film prior to the removal of the halogen-contg. material from the recording carrier. This crosslinking is executed at the intensity which is strong on the incident face side and is weak on the exit side. The recording carrier near the surface in contact with a substrate is strengthened by as much as the quantity of the balance obtd. with respect to the surface of the recording carrier and such strengthening contributes to an improvement in the adhesive strength between the recording carrier and the substrate according to this method of executing the photoirradiation from both faces. The hologram having high diffraction efficiency is thereby obtd. without clouding and cracking the hologram even if the recording carrier is subjected to an abrupt swelling or contracting treatment. The generation of the exfoliation is obviated even under the conditions of the high temp. and high temp. or the heat cycles.

Title: Thickness detector
Inventor: KIKUCHI MASAYUKI
IPC: G01B5/06
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To enable accurately measuring of the thickness of paper leaves even when a roller shaft is decentered by grasping and conveying the paper leaves with two detection rollers contacting each other on a circumference to subtract a displacement value at respective positions of the rollers. SOLUTION: Two detection rollers 1 and 2 are arranged to contact each other on a circumference to grasp and convey paper leaves 11 being rotated in the direction opposite to each other. When the detection rollers 1 and 2 grasp the paper leaves 11, the positions thereof are displaced across the thickness of the paper leaves 11 and the degree of the displacement is measured by measuring parts 3 and 4. The respective displacement values are sent to a thickness detecting section 7. The thickness detecting section 7 amplifies 8 and 9 the displacement values to be outputted to an arithmetic section 10. The arithmetic section 10 subtracts an output of an amplifier 9 from an output of an amplifier 8 to calculate the thickness of the paper leaves 11.

Title: Double-side reader
Inventor: KAGOSHIMA KAZUHARU
IPC: H04N1/04
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To read double sides of an original nearly at the same time by reading both the sides of the original with a couple of read sections arranged close to each other, making a read light incident onto a couple of linear image sensors via a single read lens respectively and by having only to move the original in one direction. SOLUTION: An original is being carried sequentially with feed rollers 2-5 and information on the front and rear sides of the original is read when the original passes through a lower side read section 6 and an upper side read section 7. The read light is made incident onto a couple of image sensors 16, 17 respectively via a single read lens 15. Thus, the information of both front and rear sides of the original is read almost simultaneously so as to quicken the read speed. Furthermore, the read lens 15 is used in common and a changeover mechanism such as a mirror is not in use, then the cost is reduced. Furthermore, since the read light from a read section 7 at an opposite side to a read unit 14 is in crossing in a front side of the carrying path so as to arrange the moving path and the optical path system overlapping with each other, then the entire configuration is formed compact.
