Patent JP-S5942162-A (JP)
Title: Production of amorphous ribbon
Inventor: NAWA MASAHIRO
IPC: B22D11/06
Filed: 1982-08-31
Abstract: PURPOSE:To obtain stably an amorphous ribbon having good surface characteristics by increasing the ejection pressure of the molten metal to be ejected toward a cooling nozzle under high speed rotation with lapse of time. CONSTITUTION:The tip of a nozzle 4 is raised upper than a hole 10b and the hole 10b is closed with a shutter 10c. A raw material for an amorphous ribbon is inserted into the nozzle 4, and an inert gas is put through a passage 10a into an electric furnace 5 to maintain the circumference of the nozzle 4 at an inert gaseous atmosphere. The raw material is melted in a furnace 5 to make molten metal 1. On the other hand, a shutter 10c is opened and the tip of the nozzle 4 is brought near a cooling roll 3 under high speed rotation; at the same time, the molten metal 1 in the nozzle 4 is ejected by the inert gas fed 7 into the nozzle. The ejection pressure of the metal 1 is increased with lapse of time in this case. The metal 1 ejected onto the circumferential surface of the roll 3 is quickly cooled while the metal contacts with the surface of the roll 3 for a certain specified distance owing to the wetting property therewith, whereby an amorphous ribbon 2 is obtd.

Title: Flowmeter for treated granular articles such as grains
Inventor: INADA TETSUYA
IPC: B02B7/00
Filed: 1986-06-27
Abstract: PURPOSE:To accurately measure a flow rate by selecting a frequency of emitted detecting ultrasonic wave which is largely different from that of ultrasonic noise produced when treated granular articles collide with one another or with the wall surface of a passage. CONSTITUTION:Detecting ultrasonic wave from a transmitter 24a is emitted toward treated granular articles, such as grains, passing in a passage. The detecting ultrasonic wave is received by a receiver 24b in accordance with the transmittivity or the reflectivity of the treated granular articles for the detecting wave and their flow rate is measured. At this time, the frequency of the detecting ultrasonic wave emitted from the transmitter 24a is made largely differ from that of ultrasonic noise produced when the treated granular articles collide with one another or with the wall surface of a passage second reducing cylinder 22. Thus, by making a sharp distinction only on the detecting wave, the magnitude of the flow rate of the treated granular articles can be simply determined.

Title: Hot-water supplier
Inventor: AOKI AKICHIKA
IPC: F23N5/00
Filed: 1986-06-27
Abstract: PURPOSE:To prevent the generation of unburnt gas as well as large igniting sound, by shifting fire from a first gas burner block to a second gas burner block before reducing the pressure of the gas. CONSTITUTION:A control unit 18 is operated by the signal of a water amount sensor 4 to operate an ignitor 11.

Title: Uneven settlement correcting method for construction
Inventor: MORITA SEIJI
IPC: E02D35/00
Filed: 1990-06-13
Abstract: PURPOSE:To control a correcting amount by setting one of hydraulic cylinders to a fixed cylinder to be a standard point, while setting the farthermost cylinder from the fixed cylinder to a control cylinder. CONSTITUTION:When an uneven settlement is generated and the lengths of pillars (a) to (m) of a construction 5 are lowered in that order, a hydraulic cylinder 1a is set to a fixed cylinder to be the standard. Then, the feeding circuit of the cylinder 1a is cut off, flow control valves 2a to 2j, and 2k are opened, and flow control valves 2j and 2m are set at the necessary correcting amount ratio of the pillars (j) and (m). Furthermore, the system pressure is set a little higher than the necessary jack-up pressure, and the speed control and the pressure control are carried out concurrently. As a result, the speed control can be carried out by all the cylinders.

Title: Display device
Inventor: HORIGUCHI TSUTOMU
IPC: H04N5/68
Filed: 1979-11-26
Abstract: PURPOSE:To suppress the power consumption in the nonsignal period, by dividing a power supply circuit of a display device into the power supplies for the system of tuner and synchronism circuits and the system of display and audio circuits, and  switch the power supply for the latter system corresponding to the presence or  absence of the synchronizing signal. CONSTITUTION:Synchronizing signals are obtained from the output of a tuner circuit 1 for the synchronism circuit 2 and a display/audio circuit 3 outputs video and audio in matching with the signals. A detection circuit 4 discriminates the presence of television signal with the information from the synchronism circuit 2, and a control circuit cuts off the power supply for the display/audio circuit from the output.

Title: Restoration mechanism for steering device
Inventor: OOSHITA SAIICHIROU
IPC: B62D3/02
Filed: 1979-11-26
Abstract: PURPOSE: To maintain the restoring force of a steering system at a prescribed level even near a straight moving condition, by attaching magnets to the body of a gear box and a rack shaft so that the magnets attract each other and that the magnets are opposed nearest to each other under the straight moving condition.  
     CONSTITUTION: Magnets 4 are secured on the inside surface of the body 1 of a gear box. Other magnets 5 are secured on the outside surface of a rack shaft 2 so that the poles of the magnets 4, 5 face each other. These magnets 4, 5 are opposed nearest to each other under a straight moving condition. When a steering wheel is much turned, the magnets 4, 5 go very away from each other because of the leftward or rightward sliding of the rack shaft 2 so that the magnets 4, 5 are not affected by their magnetic forces. For that reason, only a restoring force based on wheel alignment acts to a steering system. Near the straight moving condition, the attractive forces of the magnets 4, 5 act to the steering system to apply a double restoring force thereto as a whole. The return of the steering system after its turning is thus ensured to highly improve the stability of straight running.

Title: Stress corrosion breakage preventing method for piping
Inventor: YOSHINAGA TOSHIAKI
IPC: F16L57/00
Filed: 1977-12-21
Abstract: PURPOSE: To prevent stress corrosion breakage of stainless steel piping of the primary system of a nuclear reactor connected to a pressure vessel by removing the temperature difference between the upper and lower part of the piping near the joining part.  
     CONSTITUTION: With a shutter valve 6 closed, the high temperature water in the pressure vessel 4 and the low temperature water in the piping 5 cause temperature difference between the upper and lower part of the piping 5 near the joining part. This temperature difference is detected by temperature sensors 7, 8 and 9 provided on the upper and lower part of the piping 5 and measured by temperature difference detector 10 and 11. The measured results are applied to a controller 12. The controller 12 closes the power source switch 13 to heat the piping 5 with a heater 14 provided externally on the piping 5, thus reducing the temperature difference between the upper and lower part of the piping 5 and preventing excessive temperature difference and stress corrosion breakage of the piping 5.
