Title: Special type axial flow pump
Inventor: SATOU YOSHIO
IPC: F04D29/24
Filed: 1979-05-17
Abstract: PURPOSE: To improve pump performance by radially forming a curved surface of an impeller blade.  
     CONSTITUTION: As the fluid flowed in through the impeller rotation is compelled to rotate in the part of the radial impeller blade 2 at the impeller rotation speed, the fluid slides on said curved surface and a big dynamic pressure is generated in the part of the smooth curved surface 1 so that the liquid flows at the flow velocity produced by the dynamic pressure in the direction of the radial impeller blade. As the smooth curved surface at the impeller outlet 3 is conversely formed to the impeller inlet, the liquid, which flows on said part, while having been rotating and flowing on the curved surface with the same speed as the impeller, loses its speed almost by the rotation speed thus generating a dynamic pressure due to the reaction force corresponding to the residual rotation speed on the curved surface 3. Consequently on the impeller inlet curved surface 1 as well as on the outlet curved surface 3 generate dynamic pressures having reverse directions, and the moment of rotation negate each other producing an improved pump performance.

IPC: H04B1/74
Filed: 1985-03-25
Abstract: PURPOSE:To decrease power consumption and mounted space and to withstand a shock by using a bi-lateral switch comprising an IC for a line switching circuit for an active circuit and a spare line for transmitting or receiving a bipolar signal in a PCM communication system. CONSTITUTION:No relay is used and instead, bi-lateral switches 1-12 are used and the midpoint between potential isolation transformers T1, T2 is used as an earth potential to a signal. A control signal is used to turn on the bi-lateral switches 1-6, to turn off the bi-lateral switches 7-12, and a signal is sent via the potential isolation transformer T1 of the active line 20. In switching the line to a standby line 21, the control signal turns on the bi-lateral switches 7-12 and turns on the bi-lateral switches 1-6. Thus, the line switching circuit with less power consumption, less mounting space and withstanding shock is realized.

Title: Induction power supply device for transmission line monitoring sensor
Inventor: MINAFUJI JUNICHI
IPC: H02H1/06
Filed: 1988-03-16
Abstract: PURPOSE:To obtain the DC power of good quality easily, by shorting the output of a current transformer to obtain AC voltage from aerial wire current when it is on a predetermined voltage level. CONSTITUTION:The output of the secondary winding 2a of a current transformer 2 passed through the aerial earth wire 1a of a transmission line is rectified with a rectification circuit 3 since a thyristor 6 is unconducting at the beginning. If this rectification voltage is not higher than the operating voltage of a Zener diode ZD4, a definite DC voltage can be obtained with a voltage regulator 7. If it is not lower than the operating voltage, the potential at a point y is limited to the operating voltage by the function of the ZD4. Then, the potential at the gate (a point z) of the thyristor 6 connected to a point x will rise and it becomes conducting. When the output of the secondary winding 2a gets to negative polarity and reverse-blocking state, it becomes unconducting. With this repetition, the potential at the point y holds the voltage in which the operating voltage is set at its peak value. By inputting this voltage into the regulator 7, stable DC voltage can be outputted.

Filed: 1980-05-09
Abstract: PURPOSE:To protect a device from faults, by providing a counter, which counts high-speed clocks and is initialized when a low-speed clock sppears, and a counter which is initialized when count contents coincide with the frequency ratio of the high-speed clock to the low-speed clock. CONSTITUTION:When the input clock stops, a counter 512 starts counting; and if this state continues for approximately >=3 frames, the count value of the counter reaches a prescribed value, and as a result, the output of the decoder becomes high- level to set an FF82. This setting of the FF82 is regarded as the fixed fault of input clock break to request the route switching to the clock route switching control circuit. A counter 91 monitors the frequency ratio of the reference clock to the frame clock by the cooperative action of a counter 75 and a decoder 76. If this frequency ratio is erroneous three times continuously, the FF82 is set to issue the clock route switching request. As a result, the device is protected from not only simple clock break but also intermittent faults generated momently.

Abstract: PROBLEM TO BE SOLVED: To facilitate the inspecting work of products by forming an entire container out of transparent material so that at least the lowermost part of a packing can be visually verified over its entire circumference from the outside through the whole container. SOLUTION: A heat insulting container 1 has an inner container 2 in an outer container 3 leaving an interval of a void part 4. A transparent synthetic resin material e.g. a material with a transmissivity of 45% of visible rays is used as the materials of the inner container 2 and the outer container 3. A packing 26 is arranged between the plug body mounting part 19 of an upper part 13 and the inner container 2. As the lowermost part of the packing 26 is visually verifiable over its entire circumference from the outside through a double-wall container 5, it is possible to visually verify whether the packing 26 is arranged at a predetermined location over its entire circumference. Therefore, in the case that the arrangement location of the packing 26 is displaced in a manufacturing process, it is possible to verify containers with displaced packings immediately and to facilitate the inspecting work of products.
