Title: Manufacture of information recording medium
Inventor: KOBAYASHI TADASHI
IPC: G11B7/2585
Filed: 1991-06-14
Abstract: PURPOSE:To form a high-quality aluminum-alloy reflecting film which is free from pin holes and oxide films by forming the reflecting layer under a prescribed condition by a sputtering method by using a material which is prepared by adding at least titanium to aluminum. CONSTITUTION:A protective layer 3, recording layer 4, protective layer 5, reflecting layer 6, and protective layer 7 are successively formed on one surface of the optical disk substrate 2 of a phase-changing type optical disk 1. Of the layers, the layer 6 increases reproduced signals by optically enhancing optical changes in the layer 4 and, at the same time, has a layer 4 cooling effect. In addition, a material prepared by adding at least titanium to aluminum is used for forming the layer 4 and, when the layer 6 is formed by a sputtering method, a target which becomes the raw material of the material is sputtered after setting a vacuum of <=5/1,000,000Torr in a sputtering chamber. Since the sputtering atmosphere can be maintained in a clean state and a harmful gas which becomes an impurity can be eliminated, a high-quality reflecting layer 6 which is free from pinholes and oxide films can be obtained.

Abstract: PURPOSE:To raise the mounting density with simple construction by performing shrink coating in such a way that the film thickness is uneven part to part, and by forming transparent insulation film on an electrode. CONSTITUTION:Transparent insulation is shrink coated on at least either of a movable electrode 22 and a stationary electrode 28 in the thickness below 1mum, which differes from part to part, and thus films are provided as spacers 25, 31.

Title: Magnetic powder flaw detector for steel pipe
Inventor: OIKAWA YOSHIROU
IPC: G01N27/83
Filed: 1979-11-08
Abstract: PURPOSE: To detect internal/external surface flaws at the end of steel pipe simultaneously with the help of one unit of flaw detector by perpendicularly installing multipole synthetic magnetic field flaw detector on the upper tip of U-type yoke and a coil on the lower horizontal piece.  
     CONSTITUTION: The end of steel pipe 2 to be examined is brought to the device 1 and the steel pipe 2 is turned, making the external surface side of steel pipe 2 correspond to the side of multipole synthetic magnetic field flaw detector 4 and the internal surface side to the coil side 5. Then voltage is applied to R, S, T. Then a magnetic field is generated, resulting in the generation of a magnetic field in the flaw detector 4 and, in turn, tripolar magnetic pole 4a at the lower end of flaw detector 4. At the same time, a magnetic field is induced as far as at the internal surface of steel pipe 2 by means of yoke 3. At the same time, a magnetic field is generated in a coil 5, causing an induction magnetic field to be generated at the end of lower horizontal piece for yoke 3 to become a magnetic field 5a. Magnetic field 5a corresponds almost in the center of tripolar magnetic pole 4a. Therefore, magnetic field distributions 6a, 6b are generated on the external and internal surfaces of steel pipe 2 between the afore-mentioned magnetic poles due to each magnetic field mutual action. Thus, flaws on the internal and external flaw at the ends of steel pipe can be detected by one unit of the flaw detector.

Title: Rectangular shell-and-tube once-through boiler
Inventor: TAI SEIJI
IPC: F22B21/04
Filed: 1988-06-10
Abstract: PURPOSE:To uniform the velocity of combustion gas passing through the groups of water pipes ranging from the upper stream side to the lower stream side by setting the water pipe span on the lower stream side of the combustion gas passage wider than the water pipe span on the upper stream side. CONSTITUTION:Water pipe groups A, B, and C in a once through boiler are laid out so that water pipes 10, 11, and 12 are arranged respectively based on specified dimensions linearly. The pipe span of the water pipes 10, 11, and 12 comprising the water pipe groups A, B, and C is designed to be narrowed from the upper stream side in the direction of the combustion gas flow to the down stream side, which makes it possible to equalize the flow of the combustion gas substantially at a specified velocity from the lower stream side or the side of a burner 1 up to the down stream side or the side of a gas duct 2. In other words, although the volume of the combustion gas is large on the upper stream side, the combustion gas can flow without a marked pressure loss, since the water pipe span is wide, while on the down stream side the volume of the combustion gas is reduced, but the water pipe span is narrow, which increase the velocity of the combustion gas. Therefore, the pressure loss is minimized in a boiler drum and the recovery of heat from the combustion gas on the down stream side is higher. Furthermore, the heat transmission efficiency is higher,which makes it possible to provide higher heat transmission efficiency from the combustion throughout the entire passage as well.

Abstract: PURPOSE:To permit a sufficient amount of oil to be obtained for actuating a power steering gear, by placing an engine in a fast idle condition if an accelerator pedal is detected to be opened when a transmission is placed in a neutral position with an engine load being removed during steering. CONSTITUTION:An electronic control unit 5 inputs a signal SS from a car speed sensor 2b, signal HS from a steering angle sensor 8, signal NS from a neutral switch 2a and a signal AS from an accelerator sensor 7a, and an engine 1, when its load is removed with a transmission 2 in a neutral position during steering, is placed in a fast idle condition, in which supply fuel is increased more than that in the normal idle condition, if opening of an accelerator pedal 7 is detected in a preset car speed or more. Accordingly, an oil amount enough for sufficiently actuating a power steering gear is obtained by fully actuating a power steering pump 6. In this way, the engine, which is placed in the fast idle condition only when a delivery oil amount from the pump is really necessary, enables fuel consumption to be reduced.
