Title: Method for continuously casting molten metal
Inventor: HARA YOSHIAKI
IPC: B22D11/10
Filed: 1987-09-03
Abstract: PURPOSE:To uniformize structure in a cast billet and to prevent center segregation by collecting molten metal in an intermediate vessel under solid-liquid coexistent condition by gas-atomizing method and next, continuously supplying the molten metal into a mold while stirring. CONSTITUTION:The molten steel 4 is dropped from a ladle 1 through a tundish 2 and the atomizing gas 8 is injected against the dropping flow to make atomized drip. The drip 10 is cooled with the gas 8 and dropped into the intermediate vessel 5. The metal becoming the solid-liquid coexistent state in the air-tightened vessel 5 is rotated and stirred with stirrer 6 and poured into the mold 11, to form the cast billet 12. Then, the cast billet 12 does not have dendritic structure and is formed to desired cross sectional shape. As the cast billet 12 is formed by the drips 10, the structure of the cast billet 12 is uniformized and the development of the center segregation is prevented.

Title: Coupling method for steel pipe
Inventor: ISHIBASHI TADAYOSHI
IPC: E02D5/24
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To shorten a working-time at a work-executing site by a method wherein a gap between a first steel pipe and a hollow-form joint pipe is filled with an acryl adhesive and thereafter, a second steel pipe is locked with the joint pipe and a gap therebetween is filled with the acryl adhesive. SOLUTION: Joining between a first steel pipe 1 and an outer pipe joint steel pipe 2a is previously effected at a factory. To keep the gap of a gap 9 at a specified value, a bolt 10 is inserted and fixed by a nut 11. Thereafter, the bottom of an outer pipe joint pipe 2a is welded and sealed by a mastic elastic sealing material and an O-ring to form a seal part 5. The gap 9a is filled with a acryl adhesive 4 through an injection nozzle 6. At a site, sealing is effected by the mastic elastic sealing material and a rubber packing and after an abutment seal part 8 is formed, a second steel pipe 3 is fitted in to provide a gap 9b, and a bolt 10 and a nut 11 are inserted. The acryl adhesive is infected through an injection nozzle 7 and after filling, the adhesive is cured. This method improves working efficiency and remarkably shortens a working time.

Title: Display element
Inventor: BESO ESU TEIJIYANIKU
IPC: G09F9/33
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To facilitate observing at a wide angular range in an on-position and to mask light at the wide angular range in an off-position by attaching it so that light lights a bright side surface when a movable member exists in the on-position. SOLUTION: A disk is tilted slightly to an LED side, and its end part acts as a stop tool in an on-limit position, and thus, the bright surface 22B of the disk is lighted by a cone of LED light around an LED light axis. The LED light direction mutually depends on the disk attitude in the on-limit position, and thus, when the disk angle and the bright surface 22B are revised, a housing is re-pointed so that the light on the axis lights the bright surface 22B. Further, the light from the LED passes through the front of the disk bright side surface, and arrives directly at an observer (only in the on-position). Further, the disk masks a light leakage in the visual direction or in a visual cone until a sufficient extent in the off-position.

Inventor: YUSA MASAAKI
IPC: H03K17/60
Filed: 1987-09-03
Abstract: PURPOSE:To attain high speed switching for a constant current to a load circuit by supplying a current from a constant current source to the load circuit turned on/off by a high and low level of an input signal, and a pseudo load circuit equivalent thereto via a current mirror circuit. CONSTITUTION:A current mirror circuit 10 is provided with current supplying terminals 14, 15 and corresponding current flowing-out terminals 16, 17. The current I1 flow the terminal 17 flows a resistor 13 and fed to a drive input terminal 8. When a pulse input voltage VIN is applied to the input terminal 5, the input circuit 1 outputs an output voltage V01. When the voltage V01 is at a high level, the current I1 is made flow to the load circuit 4 as the current I0 and when low level, the current flows to the input circuit 1 via a diode 2 as the current Iin. The current from an output terminal 16 is fed to a pseudo load circuit 11 equivalent to the load circuit 4 via the resistor 12. Thus, the effect of a floating capacitor 9 onto the leading of the load drive voltage is eliminated and the current to the load circuit 4 is switched at a high speed.

Abstract: PURPOSE:To enable a fast and stable energization of a feed water pump to be attained by a method wherein a closed circulation passage is arranged between an inlet and an outlet of the feed water pump and the closed circulation passage is provided with a circulation pump and an adjusting valve. CONSTITUTION:Vapor within a pump casing can always be moved from its outlet port to its inlet port through a closed circulation passage 23 and under an operation of a circulation pump 26, resulting in that vapor is not clogged within the pump casing. As a result, it is possible to perform a warming-up operation having no irregular state with circulation vapor and so the pump casing shows a substantial uniform temperature state. At that time, since an adjusting valve 21 in the closed circulation passage 23 is adjusted to a degree of opening of the valve corresponding to an operation/stopping signal of an exhaust heat recovery boiler and a temperature signal of the pump casing, resulting in that vapor circulating within the feed water pump 22 of a proper amount can be circulated. With such an arrangement as above, it is possible to energize the feed water pump under a fast and stable restarting operation of the feed water pump.

Abstract: PURPOSE: To attain the immediate printer output for a received document of only a black/white original by allowing a transmitter side to inform the presence of a color original in a transmission document to a receiver side and allowing the receiver side to store only the received original including the color original to an image memory. CONSTITUTION: A CPU 101 controls the entire circuit and when the CPU receives a call from a transmitter side via a MODEM 105 or the like via a line, the receiver side sends an NSF/DIS including information representing the presence of color reception capability to the transmitter side. When the signal received from the transmitter side is NSS/DSC and the received page is a 1st page, the output mode is set to the memory/printer mode depending upon whether color mixed document information is present/-absent. When it is discriminated that the received page is not a color page and the output mode is not the memory mode, an image processing section 104 decodes a received white/black original and provides the output to the printer 111. Then the processing is terminated or a succeeding page is processed depending on the presence of a succeeding page and the presence of mode change.  Thus, the received document not including a color image is printed out from a printer immediately.
