Title: Radial fan with rear-faced vanes
Inventor: UDAGAWA YOSHIHIRO
IPC: F04D29/30
Filed: 1977-10-14
Abstract: PURPOSE: To obtain large air-blowing capacity with low noise by setting the blowoff angels of blades at 45° with a range of ±10° and decreasing their chord length as they near the suction side.  
     CONSTITUTION: The device is composed of a disc 1 and blades 2 that are arranged with fixed intervals on its front-side rim. Air is sucked from the front side to the axial direction and blowed to the periphery side. The blowoff angle α of a blade 2 is set to be 45°±10° against the tangent a. Also, the inside part of a blade 2 is inclined so that its chord height 1 becomes shorter as it nears the suction side 4, enlarging the suction diameter d. This structure compensates the decrease of the suction area due to the motor fixing part

Title: Support structure for telescope for space navigating object
Inventor: HOSHINO TERUOMI
IPC: G02B23/16
Filed: 1990-05-14
Abstract: PURPOSE:To reduce the weight of a lower support part, resulting in reduction of the weight of the whole of a telescope, by providing the modulus of elasticity high necessary to absorption of a thermal strain generated on an orbit and forming an upper support part providing strength and rigidity durable to vibration and impact environment during launching. CONSTITUTION:A stay 5 has the modulus of elasticity capable of absorbing a strain produced due to a difference in the coefficient of thermal expansion between a space navigation object 2 and a telescope 1. A pipe 6 hung down from the space navigating body 2 is formed in a hollow cylindrical shape with which the stay 5 is surrounded, and is secured to the space navigating object 2. A piezoelectric element 7 is mounted on the end surface of a pipe 6, and is formed in a hollow cylindrical shape expandable in the axial direction of the pipe 6. During launching of the space navigating object 2, the piezoelectric element 7 at the tip of the pipe 6 is expanded in an axial direction and presses a telescope 1 with a pressure for securing. On an orbit, the piezoelectric element 7 is contracted in an axial direction to release the telescope 1 from a constraining force thereon, and a strain generated due to a difference in the coefficient of thermal expansion between the space navigating object 2 and the telescope 1 is absorbed by the stay 5. This constitution reduces the weight of a lower support part 4.

Title: Processing method for protecting iron or iron alloy powder from oxidation
Inventor: KANEKO BUHEI
IPC: B22F1/10
Filed: 1982-07-16
Abstract: PURPOSE:To form oxidized film without variance of oxidation degree on the surface of the titled powder, by a method wherein organic solvent is made to be a specified mixed solvent in the titled method where iron base metal powder dipped into organic solvent is dried in the gas involving O2. CONSTITUTION:Iron or iron alloy powder is, in a dipping manner, processed with the mixed solvent composed of organic solvent inactive to those powder and the organic compound having higher boiling point than that of this organic solvent, being compatible therewith, and further being inactive to the titled powder. Oxidized film is formed on the surface of this wetting magnetic powder by evaporating organic solvent in the gas involving O2. At that time, a width generates in the boiling point of solvent and the speed of evaporation decreases as time passes, if conditions such as temperature, humidity, gas flow amount, etc. of atmosphere are constant. Thereby uniform and minute oxidized film is formed on the surface of magnetic powder and organic compound having high boiling point is adsorbed on its surface at the same time.

Title: Horizontal deflection device
Inventor: KITAMURA TSUTOMU
IPC: H04N3/16
Filed: 1991-05-29
Abstract: PURPOSE:To allow the device to employ an element with a small chip size by protecting an SIT and a transistor(TR) from destruction when a drive signal is stopped at the time of applying power supply of occurring fault. CONSTITUTION:A drive signal is not immediately applied to a gate electrode because of the operation delay of a drive signal generating circuit 1 at the time of applying power supply and since no drive signal is yet fed to a rectifier circuit comprising a diode 24 and a smoothing capacitor 25 this time, a negative voltage in the steady-state is not generated across the smoothing capacitor 25. A base of a TR 28 is biased positively by bias resistors 26, 27 and the TR 28 is turned on. Thus, since a base of a TR 13 is connected to ground through a resistor 29 and the TR 28, the TR 13 is cut off and no power is applied to the drain of the SIT 3.
