Title: Grooveless information recording medium disk
Inventor: WADA KOUSEI
IPC: G11B7/00
Filed: 1981-10-31
Abstract: PURPOSE:To prevent the generation of the distortion of a reproduction signal, the shortening of the life of a reproducing stylus, etc., by flattening a recording surface, by decreasing recording beam intensity for recording a main information signal in a section where another information signal is recorded adjacently. CONSTITUTION:Pits 1 which correspond to the 1st information signal (main information signal) form a spiral or concentric recording track and at its intermediate part, pits 2 and 3 which correspond to the 2nd information signal form recording tracks. When the main information signal is recorded on a recording medium disk like this, the intensity of a recording beam is made lower in a section A, where the 2nd information signal is recorded adjacently, than in the other section B, so that the surfaces of recording tracks formed by the pits 1 which correspond to the main information signal in both the sections A and B are included in the same surface.

Filed: 1991-06-19
Abstract: PURPOSE:To improve the convenience of the users and to save the labor at a station by providing a means to a superexpress ticket vendor to calculate the discounted charge when it is decided that the destination station inputted by a user is connected to a discount route. CONSTITUTION:The business routes are shown on a map and the station marks are shown on these routes at a destination station selecting part 15 consisting of a map type touch panel. The business routes include the trunk lines and the ordinary lines. When a user touches a destination station, this station is inputted and the connection or non-connection of the station is decided. That is, a main control part 23 decides whether the destination station is included in a trunk line or not after deciding that its own station is included in a truck line. Then the superexpress charge is calculated if both its own and destination stations are included in the trunk line. Meawhile the superexpress charge of the ordinary line is calculated if both stations are included in the ordinary line. The superexpress charge of the ordinary line is discounted with the connection to the ordinary line and the connection to a trunk line from an ordinary line respectively. Thus the discounted superexpress charge is calculated. Then a superexpress ticket is discharged together with the change from a ticket vending device 27, etc.

IPC: C07C241/02
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing high-purity β- hydroxyethyldimethylhydrazinium hydroxide. SOLUTION: β-Hydroxyethyldimethylhydrazinium compound containing an ethylene oxide addition by-product is reacted with 1,1'-bis-β-naphthol or the like to separate a β-hydroxyethyldimethylhydrazinium inclusion complex containing no by-product. The inclusion complex is subjected to a decomposition reaction with a carbon dioxide gas to collect high-purity β- hydroxyethyldimethylhydrazinium carbonate and/or bicarbonate. The aqueous solution of the carbonate and/or the bicarbonate is electrolyzed by using a cation exchange permeable membrane to give β- hydroxyethyldimethylhydrazinium hydroxide in the form of an aqueous solution without admixture of a by-product and other anions. In the case in which the aqueous solution contains the admixture of ammonia and N-methylethanolamine being the decomposition products of the objective substance, the admixture is removed by concentrating the aqueous solution under pressure.

Title: Optical head unit
Inventor: HIGASHIURA KAZUO
IPC: G11B7/00
Filed: 1992-07-03
Abstract: PURPOSE:To provide an optical head unit suitable for high speed rotation in which the tape can be downsized while facilitating assemblage, regulation, and control by constituting a scanning head of an optical head comprising a scanning control means, a rotary mirror, and an objective lens. CONSTITUTION:A scanning head for scanning the surface of a recording medium 2 with a scanning spot P is constituted of an optical head comprising a scanning control means, a rotary mirror HM, an objective lens 7, and the like. A rotary mirror M1, the objective lens 7, and a holding member constitute a rotary system. Laser beam from a semiconductor laser LD passes through a collimator lens CL to produce a substantially parallel beam which is subsequently condensed to be focused at position K. Subsequently, the beam passes through the objective lens 7 and forms a scanning spont on the recording medium 2 thus scanning the medium 2 obliquely as the medium 2 is being fed. This constitution obviates the necessity of making thick the tape in order to ensure strength thus realizing a downsized tape.

Title: Heat-radiating, rust-preventive paint
Inventor: SAKUMA YOSHIO
IPC: C09D201/00
Filed: 1984-08-25
Abstract: PURPOSE:To provide a heat-radiating, rust-preventive paint which does not require any treatment of substrates and can reduce the number of steps, by using, as a pigment, particles and powders of a material having higher thermal conductivity than that of a material to be coated to widen the radiating surface area. CONSTITUTION:A rust-preventive paint contains, as a pigment, particles and powders of a material having higher thermal conductivity than that of a material to be coated to widen the radiating surface area. In applying the paint, the surface of a heat-generating material to be coated is sandblasted. When the paint is applied thereto, the paint is closely deposited on the surface by means of the powders, solids and other material (vehicle, additives, diluent etc.). Since the solid having good thermal conductivity is in contact with the surface 2 of a heat-generating material, heat is absorbed. Since the surface of the solid 3-b having good thermal conductivity is uneven, its surface area 3-c is wider than the surface 2 of the material to be coated and hence a high radiating effect can be obtd.

Title: Precision rolling method for steel bar
Inventor: FUJITA YONEAKI
IPC: B21B1/16
Filed: 1981-11-06
Abstract: PURPOSE:To produce steel bars of high dimensional accuracy by introducing at least one unit of rolling mills of small diameter rolls into finishing mill groups and rolling the steel bars between said rolling mills and the rolling mills in the fore stage thereof or between the rolling mills of the fore stage and the rear stage without tension. CONSTITUTION:At least one unit of rolling mills provided with work rolls of <=10 specific roll diameter are provided in finishing mill groups of a continuous rolling mill group line for production of steel bars by rolling, and the steel bars are rolled without tension between said rolling mills and the rolling mills in the fore stage thereof or between the rolling mills in the fore stage and rear stage. Since the rolling mills of small diameter rolls can decrease the change in the width size of outlet side materials despite the variation in the height sizes of inlet side materials, the fluctuations in the height size are reduced by tensionless control between the front and rear stages to absorb the variance in the width size by said rolling mills of small diameter rolls, whereby the precision rolling of the steel bars is made possible.
