Title: Magnetic recording medium
Inventor: HANAI KAZUKO
IPC: C09D5/23
Filed: 1983-06-30
Abstract: PURPOSE:To obtain a magnetic layer having excellent resistance to wear by incorporating polyisocyanate as a binder in said layer and controlling the ratio between (urethane bond + allophanate bond) and (urea bond + biuret bond) in a specific range. CONSTITUTION:This invention relates to a binder system whcih consists of a main binder formed by dispersing a vinyl chloride copolymer and/or nitrocellulose and is mixed with polyurethane and polysocyanate. The production of a recording medium is accomplished by adding moisture to the recording medium to accelerate teaction between the polyisocyanate and water and to increase the forming ratio of (urea bond + biuret bond). The recording medium is then heat- treated at a relatively low temp. the forming ratio of (urethane bond + allophanate bond) is increased if the recording medium is treated in the form of a roll without adding moisture thereto. The ratio between the (urethane bond + allophanate bond) and the (urea bond + biuret bond) is controlled by incorporating a catalyst into the magnetic layer or the like. The ratio is maintained at 85:15-60:40.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a dedicated negative power source and to prevent the transistor of drive circuit from being broken by providing a horizontal deflection circuit having wiring for connecting the power source of horizontal deflection output circuit and the horizontal deflection output circuit side of capacitor. SOLUTION: A capacitor 21 is inserted and the drive circuit sides of power source 7 and resistor 8 are connected through a resistor 22 and made ground by eliminating the negative power source. Because of this capacitor 21, an AC component Vg corresponding to a signal Vi of input terminal 17 is loaded to the gate of electrostatic induction type transistor (SIT) 1. Concerning this signal Vi, when a transistor 9 is turned on and a transistor 10 is turned off, the SIT 1 is turned on and after a charging current (Ig) for gate capacity flows through the capacitor 21, a gate current for lowering ON resistance flows through the resistor 22. When Vi is H, the SIT 1 is turned off. At this point, since a negative voltage VGS is loaded to Vg, a negative electrode can be eliminated and even when the SIT 1 is broken, a current can be shielded by the capacitor 21.

Title: Curved stacking method for axial compressor
Inventor: NOGAMI RYUMA
IPC: F04D29/52
Filed: 1995-05-18
Abstract: PURPOSE: To realize a curved stacking method capable of reducing the total pressure loss of the stationary blade of an axial compressor and designing the stationary blade in a short time. CONSTITUTION: After determining the contour map of the total pressure loss near the trailing edge 16 of the stationary blade 2 with a straight stacking line, the stacking position in each span between stationary blades travels to the contour line of 20% of a total pressure loss in a negative pressure face side 27 to form a trailing edge 6. Since this determines the travel of curved stacking concretely, eliminating trial and errors, which reduces designing time. The reduction of the total pressure loss due to a stationary blade improves the efficiency of a compressor, and a thin wing boundary layer improves the flow rate of the compressor, reducing bad influence against a rear stage.

Abstract: PURPOSE:To compensate for the shortage of faucet fed water pressure while feeding quickly water by providing an impeller of a motor pump and a water intake path provided with a connection connected to a faucet at one end both in positions lower than the faucet. CONSTITUTION:An end of a water intake path 28 is connected to an impeller 24 and the other end connected to a connection 30 connected to a faucet disposed above the impeller. When the faucet is opened at first before running, the water intake path 28 and impeller 24 are sunk under water by natural drop of water from the faucet. And when a switch 56 is closed, a motor 20 is rotated to drive rotatably the impeller 24 and thereby start the water absorbing action. Water from the faucet is absorbed in the impeller 24 section through the water intake path 28 to ascend through a path 46 with increased pressure and flow into a water feed pipe 48. Thus, the motor 20 is water cooled through an inner tube 38 and water further flows down through the water feed pipe 48 to provide high pressure water supply. By said constitution can be compensated for the shortage of water pressure in the faucet 10 while water can be quickly supplied.
