Title: Multi-stage pump hydraulic turbine
Inventor: TSUZUKI KOUICHI
IPC: F03B3/10
Filed: 1981-12-18
Abstract: PURPOSE:To minimize the entire pressure loss in a return channel when a pump is driven by moving a return channel guide vane adjacent to a guide vane, while being linked to said guide vane. CONSTITUTION:When a ring 12 is turned clockwise or counterclockwise, the turning motion is transmitted via a connection rod 11 to arms 21 and 10 so that a guide vane 5 is turned around a supporting shaft 6. The guide vave 5 and the movable part 4a1 of a return channel guide vane 4A adjacent to said guide vane 5 are simultaneously turned, whereby when a pump is driven, fluid running from the guide vane 5 flows into a return channel guide vane 4A at an optimum inflow angle regardless of the opening angle of the guide vane 5. On the other hand, when a hydraulic turbine is driven, the fluid flows into the return channel guide vane 4A.

On the other hand, the inlet gas temp. of the boiler 2 is detected by the signal of a thermometer 7 in a 2nd arithmetic controller 8 which calculates the difference from a set temp. and transmits an on-off signal to a 2nd flow rate control damper 9. The damper 9 is closed (opened) to decrease (increase) the amt. of the outdoor air to be sucked when the above-mentioned gas temp. rises (lowers) above (below) the set value. As a result, the gas temp. is decreased (increased). The amt. of the outdoor air to be sucked is thereby controlled while the specified flow rate of the gas to be passed through the fan 4 is maintained. The above-mentioned gas temp. is thus stabilized.

Abstract: PURPOSE:To improve operation frequencies by reducing superposition on a gate electrode by shallowing a source and a drain region by a method wherein ion implantation for forming both the two regions is performed at a specific acceleration voltage, and heat treatment is performed at a specific temperature. CONSTITUTION:A gate oxide film 2, a field oxide film 3, and a poly-crystalline Si gate part 5 are formed on an N type Si substrate 1.

Title: Evaporator for absorption type refrigerator
Inventor: TANI HIDEKI
IPC: F25B39/02
Filed: 1993-07-28
Abstract: PURPOSE:To improve the heat transfer performance of an evaporator by simple means by heating and oxidizing a copper tube constituting a heat transfer tube in the air until its surface becomes brown or dark brown, and thereby forming an oxide film having a finely uneven surface. CONSTITUTION:A copper tube constituting a heat transfer tube A of an evaporator 8 is heated and oxidized in the air until its surface becomes brown or dark brown, thereby forming an oxide film having a finely uneven surface on the surface of the tube. Thus, since it holds water by capillarity and hydrophilic nature of the film, water dropped to the surface of the tube is excellently spread so that the entire surface of the tube is moistened, and an effective heat transfer area is increased. Further, the surface of the formed oxide film is treated with absorption solution or alkaline solution thereby to remove only cupric oxide on the surface of the finely uneven surface structure of the tube. Thus, when the surface layer is immersed in the absorption liquid, impurities are not dissolved in the solution.

Filed: 1986-09-03
Abstract: PURPOSE:To improve sensitivity and to permit recording with a bias magnetic field of an adequate magnitude and laser power of small power by forming magnetic layers of laminated films of 2 kinds of compensating temp. recording materials satisfying specific requirements. CONSTITUTION:This recording medium is formed by having at least the two magnetic layers 3, 4 both consisting of an amorphous alloy of a rare earth element and transition metal and having the compensating temp. higher than an ordinary temp. on the substrates 1a, 1b. The two magnetic layers 3, 4 have the same sensitivity at an ordinary temp. One layer 4 of the two magnetic layers is larger in the coercive force near the compensating temp. than the other and the temp. dependency of the coercive force near the compensating temp. is lower. The coercive force which the magneto-optical recording medium exhibits shows the intermediate dependency of the temp. dependencies of the high coercive force layer 4 and low coercive force layer 3 by the exchange bond of both layers 4, 3. Since the magnetic layers having such temp. dependencies, the recording is executed by the bias magnetic field of the not too large and adequate magnitude and the light beam energy.
