Title: Optical information recording medium
Inventor: NAGATE HIROSHI
IPC: G11B7/24073
Filed: 1986-12-27
Abstract: PURPOSE:To permit easy formation of an original disk by alternately forming guide grooves for tracking and information pit arrays on a disk, thereby forming spiral signal patterns. CONSTITUTION:The tracks 2 for guiding and the information pit arrays 3 are alternately formed on a line of spiral centering at the center P of rotation (center of center hole 5) of a substrate 1. Reading out of the information from the information pit arrays 3 and writing of proper user's information onto the guide tracks 2 are, therefore, possible. Writing of the user's information associated with the information to be red out of the information pit arrays 3 onto the next guide track continuous with the information pit arrays is consequently possible. The formation of the original optical information recording disk is thereby permitted.

Title: Method for manufacturing plastic extruding member
Inventor: NIIMURA TATSUO
IPC: B29C48/06
Filed: 1987-12-09
Abstract: PURPOSE:To obtain a plastic extruding material with a smooth surface and without any cooling stripes by lowering the surface tension of cooling water through mixing interfacial active agent to cooling water for cooling extrusion member extruded from a extruder. CONSTITUTION:A covered electric cable (an extruding material) 2 formed by extrusion in an arrow direction from the die 1 of an extruder is cooled by pouring the cooling water 4 from a cooling water spouting device 3. The cooling water 4 is mixed with interfacial active agent. The interfacial active agent is specially preferable to liquid detergent in view of its dissolution. The mixing ratio is excellent in approximate 20PPM-1,000PPM. When it is below 20PPM, the effect is low, and above 1,000PPM, bad effects such as foam generation or the like may occur. The side of the die 1 on an upper surface of the covered electric cable 2 poured with cooling water 4 can be uniformly cooled minute by minute without forming any rising portion of cooling water, so that a plastic extrusion member with a smooth surface and without any cooling stripes can be produced.

Filed: 1991-11-25
Abstract: PURPOSE:To set a condition for maintaining lighting of a discharge lamp to a low flux level properly by using a circuit for combining a DC current with the discharge lamp lighted at a high frequency for detecting a filament resistance of the discharge lamp, and determining the sort of the discharge lamp. CONSTITUTION:A high-tension winding of a step-down transformer T2 is connected to an AC power supply E. Full-wave rectification is performed to an AC low voltage obtained at a low-tension winding of the transformer T2 by a bridge circuit of diodes D7-D10, and a capacitor C6 for smoothing is charged by a rectification output, so a specified low voltage is obtained by voltage regulation by a Zener diode ZD1. This DC voltage is used for an actuation source of a control circuit, and it is also applied to non-power supply terminals of filaments fa, fb of a discharge lamp through an inductor L3, a diode D11, and a resistance R1. This DC combining circuit 7 makes the discharge lamp 1 to light stably with a low light flux. By detecting a DC current flowing from the circuit 7 through the filaments fa, fb, a switching element Q6, and a primary winding of a preheating transformer T1, the sort of the discharge lamp 1 is determined.

Title: Enclosure for electronic equipment
Inventor: SUGINO MORIHIKO
IPC: H05K5/00
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To provide an enclosure for electric equipment for preventing warpage or pealing from being generated. SOLUTION: An aluminum plate 11 and a resin layer 12 are joined via a nonwoven fabric (a fiber structure made of thermoplastic resin) 13. The nonwoven fabric 13 acts as an adhesive and adheres to the aluminum plate 11 in a point or line. In this manner, by providing a nonadhesive part, the net structure of the nonwoven fabric remains deformed, thus absorbing the shrinkage difference between the aluminum plate 11 and the resin layer 12 for preventing warpage from being generated easily.

Abstract: PROBLEM TO BE SOLVED: To suppress the etching shift quantity of an Mo film to an Al film in a TFT, by forming each of conductor layers connected respectively with its drain and source which are formed on an insulation substrate region out of a laminated structure comprising an Al based metal film and an Mo film containing nitrogen. SOLUTION: As a wiring 10 for the source or drain of a TFT, an Al alloy film 8 of 500nm in film thickness is formed in the atmosphere comprising an Ar gas of 10sccm and a gas pressure of 3.0×10<-3> Torr. Thereon, an Mo film 9 of 150nm in film thickness is formed in the atmosphere comprising an Ar gas of 20sccm, an N2 gas of 10sccm and a gas pressure of 3.0×10<-3> Torr. The Al and Mo thin films 8, 9 are patterned by wet etching which is performed dipping them into the mixture of phospheric, nitric and acetic acids and water, making the simultaneous etchings of these two film layers 8, 9 possible. Since the Mo film 9 constituting the two-layer structure together with the Al film 8 is formed in the atmosphere containing nitrogen, the etching shift quantity of the Mo film 9 to the Al film 8 can be suppressed to be small.

Abstract: PURPOSE:To prevent mutual diffusion of Al and Si and to decrease resistivity, by employing electrode structure of the following layers: a titanium layer formed at least on a contact region of a semiconductor substrate, a titanium nitride layer containing Al, and a wiring layer involving an Al part. CONSTITUTION:A P Si substrate 1, where a contact window is formed in a SiO2 layer 2 and a PSG layer 3 which are disposed on a P<->Si layer 1 in which a contact region is formed of a n<+> layer, is set in a sputter evaporation machine. Al and Ti are incorporated in a target on the sputter evaporation machine. First, Ti is sputtered 500Angstrom  in an atmosphere of Ar so as to form a Ti layer 4. Next, Ti and Al are simultaneously sputtered in a mixed gas of N2 and Ar so as to form a TixNyAlz layer 5 of 1000Angstrom  in thickness. Then, a ratio of Ti to Al depends on that between both materials for the target, and a ratio of Ti to N depends on the gas ratio of N2 to Ar. A surface of the Ti target is nitrided and it is beaten by Ar ions. Similarly, a TixNyAlz layer 5 is sputtered together with the Al beaten, and finally Al is sputtered 4000Angstrom  in thickness under an atmosphere of Ar, so that an Al layer 6 is formed.
