Title: Power generating equipment
Inventor: KANEKO KAZUHIKO
IPC: F04F1/18
Filed: 1979-05-05
Abstract: PURPOSE: To obtain an efficient energy by leading the water in a low position to a high position using a bubble pump, and generating power using a head thus  created.  
     CONSTITUTION: The water above a nozzle 20a in a water lifting pipe 18 is mixed with air bubbles, and the specific gravity is remarkably smaller. Therefore, the water in the water lifting pipe is pushed upwards by the water pressure outside the pipe and elevated to a position higher than the water surface 24, and in consequence, the water outside of the water lifting pipe is led to the water lifting pipe continuously through an opening 18. While the mixture of water and air is passed through an air suction chamber 24, air is drawn out, and water only is led to a reservoir 14. A power generating turbine 30 is driven by the pressure of the water fed from the reservoir 14 through a pressure line 28, and an energy is thus obtainable with high efficiency.

Title: Meter sensor calling system
Inventor: KOBAYASHI TADASHI
IPC: G08C15/00
Filed: 1988-03-08
Abstract: PURPOSE:To constitute a economical system by connecting several types of plural meter sensors to the same communication line, and transmitting data only with the meter sensors in the same type by means of a command from a meter center. CONSTITUTION:Plural types of plural meter sensors 11-13 are connected to the same communication line L. The meter sensors 11-13 detect the consumption of gas, electricity and water. Calling signals 1-3 at a voltage and frequencies fixed beforehand are sent from meter sensors 11-13 through a switch SW to the communication line L. When the respective meter sensors 11-13 detect the calling signals by a calling signal detecting circuit 21..., the reading of the meter in the type designated by data transmitting circuits 22... is transmitted in a sequence fixed beforehand, and it is received by a receiving circuit 4. Thus, the data of the three types of the meter sensors can be transmitted by a single communication line L, and the economical system can be constituted.

Title: Active type pulsation pressure absorber
Inventor: SHIOKAWA SHOJI
IPC: F04B11/00
Filed: 1991-03-20
Abstract: PURPOSE:To easily obtain the displacement amount which is given to the pulsation pressure generating means with a simple and inexpensive structure, and absorb pulsation pressure efficiently by measuring directly the amount of non- steady flow discharged from a pulsation pressure source, and generating fluid pulsation pressure so as to negate a volume change by a flow rate change. CONSTITUTION:A pulsation pressure source 1 on one end and a load on the other end are connected to each other by a fluid pressure circuit 2. A pulsation generating means 4 which generates fluid pulsation pressure by applying voltage to a piezoelectric element 3 is disposed in the mid of the fluid pressure circuit 2. At this time, a non-steady flow amount measuring means 7 which measures the amount of non-steady flow fluid discharged from the pulsation pressure source 1 is disposed at the fluid circuit 2 on the pulsation pressure source 1 side near the pulsation pressure generating means 4. Besides, voltage applied to the piezoelectric element 3 is controlled by a pulsation pressure absorption control means 8 so as to negate the measured flow rate change. It is thus possible to obtain displacement amount easily for effective absorption of pulsation pressure without adding a sensor and its control as well as adjustment by a change in the fluid pressure circuit.

Title: Flaw detection head
Inventor: YAMADA NAOTO
IPC: G01N29/28
Filed: 1990-03-07
Abstract: PURPOSE:To suppress an ultrasonic wave medium which flows out at when flaw detection is not performed and to hold the ultrasonic wave medium stably in a holder by fitting a slide block to a holder and sliding and holding a shoe. CONSTITUTION:A pressing-down force operates on the shoe 5, held by the holder 3 and slide block 9, by the ultrasonic wave medium 7 along the slide block 9 at all times. The shoe 5, therefore, abuts on a material to be inspected and the opening part of the shoe 5 is closed with the pressing-down force except when a pressing-up force operates along the slide block 9 against the pressing- down force. Consequently, the ultrasonic wave medium 7 is prevented from flowing out when the flaw detection is not performed, the supply amount from an intake 8 is suppressed, and the ultrasonic wave medium 7 can stably be held in the holder 3. The flaw detection can be performed right after the shoe 5 abuts on the material to be inspected.

Title: Processing of yoke in universal joint and the like
Inventor: SEI TAKETOMI
IPC: F16D3/26
Filed: 1986-03-13
Abstract: PURPOSE:To enable a yoke to be processed without producing a crack and the like by causing the bottom of its raw material to be in a plastic deformation with a boss-forming punch so that there is provided a recessed part equivalent to an opening which is thin in its wall thickness, and subsequently punching the recessed part with a pierce punch. CONSTITUTION:A recessed part 11 is provided on part, equivalent to an opening 8, of the bottom 6 of a work piece W, whose side is processed in a U-shaped form. In this process, a boss-forming punch 23A is used to apply a press working to the bottom 6 of the work piece W so that the wall thickness of the recessed part 11 is made thinner. Subsequently, said recessed part 11 is punched with a pierce punch 24A. Further, the bore diameter of the pierce punch 24A is almost equal to that of the opening 8, and moreover, in order to cope with said punching operation, an acceptor mold 24B is also provided with a by-pass port which can accept the remaining work piece W after the recessed part 11 is punched. Hereby, at the time when a yoke is processed, the opening is not punched before the final stage in the processing is reached, and accordingly, the peripheral part of a soket can be processed precisely.

Abstract: PURPOSE:To make the increase of dot density, the speed up of printing speed and the miniaturization of head possible by controlling the rise of the cooling temperature of heating part, by a method wherein a space is provided in a substrate and only a gas is enclosed therein as heating medium. CONSTITUTION:A substrate 1 has a space therein and only a gas is enclosed in this space as heating medium. For example, the substrate 1 is made of aluminum sheet 1a of 2mm. in thickness presenting the boxy state of 10mm. in height in which a space is formed and helium gas 1b of 1atm. is enclosed in this space. Thereby, the heat generated at a heating part 2 is absorbed into the helium gas 1b enclosed in the space of substrate 1 via the aluminum sheet 1a of high heat conductivity and the heat absorbed in the helium gas 1b is emitted from the bottom surface 1c of aluminum sheet 1a. At the same time, because helium gas 1b has a good heat conductivity, the temperature of helium becomes uniform in abovementioned space, the temperature rise with the passage of time of heating part 2 is restricted and at the same time, the temperature distribution of heating part 2 is equalized.

Abstract: PURPOSE:To assure the voidless low thermal resistance bonding process excellent in mechanical strength by a method wherein a melting material as an intermedi ate material is previously provided in the region along the periphery of bonded region such as a semiconductor pellet or a wiring substrate to be heat-melted in the atmosphere at specified pressure. CONSTITUTION:Specimens (an Si chip 11, a solder preform 13 and a heat sink 14) are mounted on a heating base provided in an exhaust system 16 while the atmospheric pressure is reduced down to 1torr. Due to the naturally made minor gaps, the pressure in the inner region 17 of solder preform 13 is immedi ately reduced down to 1torr to heat-melt the solder preform 13 at around 220 deg.C augmenting the liquidity for creating the close contact state or intermetal reac tion state between the metalized layers 12 and 15. The atmospheric pressure is restored to the normal pressure of 760torr with the solder preform 13 heat- melted as it is. Through these procedures, any external pressure is applied on the melted solder preform 13 to reduce the volume of inner region 17 marked ly. Finally, heating process is stopped to bond the solder 13 so that the specified substantial voidless solder bonded structure may be manufactured.
