Title: Nozzle controlling apparatus for pelton waterwheel
Inventor: EJIRI TADASHI
IPC: F03B15/20
Filed: 1984-03-28
Abstract: PURPOSE:To suppress the variation of the output of a waterwheel when the number of operation nozzles is switched, by temporarily suspending a nozzle operation controlling motor. CONSTITUTION:A plurality of nozzles are provided, and a low-value precedence mechanism 30 is installed between the cam 26 and the needle pressure distribution valve 27 of a controller A for one of the above-described nozzles. Said mechanism 30 compares the needle-valve operation amount by the cam 26 and the needle-valve operation amount by a nozzle-operation controlling motor 31. A needle pressure distribution valve 27 is operated according to the less operation amount. Into the nozzle operation controlling motor 31, the operation electric power S2 is input through a temporary suspension relay 34. The operation electric power S2 is input into the controlling motor 31 from a nozzle switching apparatus 32, and the needle pressure distribution valve 27 is operated. When the signal of a governor amplification part 21 exceeds a set value, the temporary suspension relay 34 is operated by the signal of a switch signal generator 35. Then, the operation electric power S2 is suspended temporarily.

Title: Carrier wave regenerating device for unbalanced 4-phase modulated wave
Inventor: TANO KUNIO
IPC: H04L27/227
Filed: 1979-05-16
Abstract: PURPOSE:To secure the regeneration of the carrier in the best condition at all times, by detecting the phase error component of the carrier, obtaining the DC error component from the output of the above detection to apply it to the adder and then sending the output of the adder to the voltage control oscillator to form the carrier phase synchronous loop. CONSTITUTION:The input signal of the carrier containing two bit rates is divided into two parts through distributor 1 to be led to BPF2 and 9. And the outputs of BPF2 and 9 are distributed to phase detector 4 and 5 as well as 11 and 12 each by distributors 3 and 10. Here detectors 4 and 11 detect the I (same phase as the reference phase) component to DATA1 and 2 to then deliver the data; and detectors 5 and 12 detect the phase error component of the carrier. Thus the DC error component is obtained from the data detected to be applied to adder 18, and the output of adder 18 enters voltage control oscillator 20 to form the carrier phase synchronous loop. In this way, the carrier can be regenerated at all times and in the best condition.

Title: Power supply control device for electric hot water heater
Inventor: YAMAMOTO YUTAKA
IPC: F24H1/18
Filed: 1989-03-13
Abstract: PURPOSE:To obtain a power supply control device which can supply control power from midnight power source and use low cost capacitors by storing a temperature of an upper part of a hot water storage tank and power supply length of midnight power and selecting the application of peak shift time control based on said memory data. CONSTITUTION:A memory means 13 which stores and maintains memory data even when no midnight power PW is available, is provided. The use of memory data stored in this memory means makes it possible to judge whether it is a regular midnight power PW supply starting time or a recovering time from power failure, thereby discriminating the presence of peak shift. When peak shift is present, peak shift time can be calculated by using a temperature in a hot water storage tank WT, which allows midnight power WP to be used for control power source. This construction eliminates the need for wiring for commercial power supply. Furthermore, an attempt to back up the memory means 13 alone will be sufficient if no power supply is available. Therefore, even if an attempt is made to use a low cost capacitor or the like as a back up component, it will be possible to realize a highly reliable and long time back up performance at ease.

Title: Sand-flash facility
Inventor: KONISHI AKIHIKO
IPC: E02B8/02
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To flash sand without lowering the water level of a dam lake and without setting a water discharge pipe to the opened channel state by erecting an inner tube connected to a splash pipe and an outer tube having an intake/ exhaust port at the upper section, and flashing sand via a siphon action. SOLUTION: When the water level of a dam lake is increased by a flood and the water level between an inner tube 6 and an outer tube 7 is increased to exceed the height of the inner tube 6, water flows into the inner tube 6 and is discharged to the downstream side from a gate or a valve 12 through a splash pipe 11. When the water level is further increased, the air in the space between the outer tube 7 and a ceiling is hauled together. When the hauled air quantity becomes larger than the intake air quantity from an intake/exhaust port 9, a siphon action is suddenly satisfied, and a drain is started at a stretch.  The sediment on the water bottom in a wide range is gradually collected near a bottom plate 10 by the synergic effect of this abrupt drain, the turning stream generated by a jet device 13, and a rectifying base plate 10, and it is finally sucked up between the inner tube 6 and outer tube 7 by the siphon action and is discharged to the downstream side through the splash pipe 11.

Title: Volute pump
Inventor: SHINKOU YASUSHI
IPC: F04D29/22
Filed: 1984-03-30
Abstract: PURPOSE:To reduce noise by forming a stepped part onto a shroud so that the characteristic frequency of a vane wheel differs from the frequency of the fluid which flows in a volute pump and varying the characteristic frequency of the vane wheel and preventing the resonance by absorbing the vibration and pulsation of fluid. CONSTITUTION:A front-surface shroud 5 has a stepped part 5d between a center part 5b and an outer peripheral part 5c, and if the thickness of the center part 5b is t0 and that of the outer peripheral part 5c is (t), t/t0=0.6. When the relation between the pumping amount of a volute pump and noise level is measured, the characteristic shown by D in the figure is obtained. When the relation in the conventional volute pump is measured under the similar conditions, the characteristic shown by C in the figure is obtained. This comes from the fact that the characteristic frequency shifts largely and the resonance with the vibration of fluid can be prevented, since the stepped part 5d is formed onto the front surface shroud 5, and thus noise can be reduced markedly.

Title: Plasma arc welding method
Inventor: KITAHASHI MASAMITSU
IPC: B23K10/00
Filed: 1994-03-30
Abstract: PURPOSE:To stably weld a surface treated steel sheet and to attain a high welding quality by dividing a welding process into the removing process of a surface treated substrate different in welding condition and regular welding process. CONSTITUTION:In plasma arc welding by which a surface treated metal is welded by a substance having boiling point lower than the melting point of a base material to at least one side out of plural materials to be welded, a welding process is divided into two. First of all, in a removing process of the surface treated substance, a hole for degassing is holed on a work on the front side, and the stem of the surface treated substance is actively vaporized. After that, by returning a welding current or a plasma gas flow rate to the condition for the regular welding, the works on the front side and the rear side are melted and welded. The hole for degassing can be made so that a metal to be melted rises on the outer side of a part irradiated by an arc by the pressure of the arc, and the metal to be melted is not blown out. The welding condition of the regular welding is determined by the material and the thickness of the work or the attachment amount of the surface treated substance. The welding condition for removing the surface treated substance, must be larger than that of the regular welding.
