Title: Ink jet recorder
Inventor: FURUKAWA TATSUYA
IPC: B41J2/175
Filed: 1985-02-25
Abstract: PURPOSE:To prevent bubbles generated in an ink supply tube during a long unused period by providing a value mechanism near a head of tubing and sending ink into the head after discharging ink from the tubing into a tank side at the time of starting an injection. CONSTITUTION:Under a condition at the time of non-injection, the EXH of an electromagnetic valve A is connected to the tank side and the head of an electromagnetic valve B to EXH, so that the internal pressure of a head is opened to an atmosphere as shown by (a). If a power supply is turned ON, and the electromagnetic valves A and B are driven the EXH of the electromag netic valve A is connected to the pump side and the EXH of the electromagnetic valve B to the tank side (b). At the same time, ink is discharged to the tank side through the electromagnetic valve B. when the unit is left as it is for a long time, bubbles generated in an ink tube are discharged to the tank side from the electromagnetic valve B. Next, the electromagnetic valve A is closed, and the pump and the head are connected (c) to commence an injection. In addition, if the electromagnetic valve A is closed (a), the pressure in the head rapidly reaches the atmospheric pressure level, thus assuring smooth ink circula tion.

Title: Parallel connecting method of transistor
Inventor: KAWAMATA SEIICHI
IPC: H03K17/12
Filed: 1984-02-28
Abstract: PURPOSE:To decrease the collector current unbalance by connecting in a way of crossing between a base of one transistor (TR) of TRs connected in parallel and an emitter of the other TR mutually with an element having an optional impedance so as to eliminate a current balancing reactor. CONSTITUTION:The element Z1, Z2 having optional impedance are connected in a crossing way respectively between each base and each emitter of TR1, TR2 connected in parallel. In the circuit above, if the TR2 is turned on early at switch- on for example and it shares all the circuit current, since the rise in the emitter level of the TR1 is slow, the turn-on of the TR2 is suppressed through the Z1 so as to urge turn-on of the TR1. Even when the current of the TR1 is attenuated earlier than the current of the TR2 at switch-off similarly, the current attenuation of the TR1 is suppressed and the current attenuation of the TR2 is urged simultaneously. The TR1, TR2 are fed back mutually in this way so as to share equally the current at all times.

IPC: B22D11/06
Filed: 1984-02-28
Abstract: PURPOSE:To produce a steel sheet having excellent resistance to hydrogen induced cracking without central segregation by casting a molten steel to a thin billet by a synchronous belt caster having a specified cavity thickness and using such thin billet as a blank material for rolling. CONSTITUTION:An overflow spout 2 pours the molten metal from a tundish 4 into the casting area (cavity) formed in the spacing part between two water-cooled casting belts 1 and 1 of a synchronous belt caster having the cavity set at <=60mm. thickness. The molten steel cast into the cavity forms solidified shells 6 by contacting with the belts 1 and forms a thin billet 7 in short time during moving. The billet is drawn without undue stress. The steel sheet which does not contain the internal defects occurring in central segregation, etc. and has excellent resistance to hydrogen induced cracking is thus produced with decreased man- hour and improved efficiency at a low cost.

Abstract: PURPOSE:To efficiently remove the harmful chemical materials, microaggregate and white blood cells which are the cause for a side effect from blood for blood transfusion by packing active carbon fibers and extremely fine fibers of 0.1 to 10.0mum fiber diameter into a device having an inlet and outlet for blood. CONSTITUTION:The org. chemical materials are efficiently and safely removed together with the harmful blood cell components, such as white blood cells, platelets and microaggregate, from the whole blood pharmaceuticals and concd. red cell liquid by using the active carbon fibers and the extremely fine fiber non-woven sheets. The diameter of the extremely fine fibers for removing the white blood cells is preferably 0.1 to 10.0mum, more preferably 2.0 to 8.0mum. The danger of generating a hemolysis increases at the point where the fibers are partially dense if the diameter is <=0.1mum. The affinity of the fibers and the white blood cells weakens and the weight per unit area increases to increase bulkiness with the fiber diameter of >=10.0mum.

Abstract: PURPOSE:To eliminate the fluctuation of the measured value due to a higher harmonic and to make it possible to measure electric energy by removing the higher harmonic component obtained by Fourier transformation, obtaining the voltage and current in positive phase, and further obtaining the effective power and the reactive power. CONSTITUTION:Sampling data yk-yk-11 of the voltages and the currents of an electric power system at every 30 degrees of the electrical angle are collected for one cycle.

IPC: H01L21/027
Filed: 1993-02-26
Abstract: PURPOSE:To provide an excellent pattern to reduces the effects of a wafer and to form a highly reliable electrode wiring layer by forming a coating film on a wafer at first and then a carbon-containing coating film on the surface of the coating film and eliminating the coating film after the formation. CONSTITUTION:A silicon wafer 1 is prepared. A borophosphosilicate glass(BPSG) film 2 is deposited by an ordinary CVD method so that a 80mum thick film may be formed on the wafer 1. Then, a 5wt.% aqueous solution of a maleic anhydride and acrylic acid copolymer (mean molecular weight 10000) is applied by spin-coating so that a film of 20mum thickness may be formed, thereby forming a coating film 3 on the BPSG film 2. During this operation, the transfer of the wafer between the BPSG film deposition and the coating film formation is carried out in a nitrogen atmosphere so that the wafer is not exposed to the air. Then, the coating layer 3 is removed by cleaning the surface of the wafer for 30 secondes, thereby exposing the surface of the BPSG film 2.

Abstract: PROBLEM TO BE SOLVED: To improve contact between a photographing roller and film by switching a nip roller by a switching operator so that only the nip roller on a film supply side may be elastically brought into contact and the other may be separated. SOLUTION: When a cassette is attached with its front surface side out, the switching operator 99 is turned clockwise.

When the cassette is inverted and attached with its back surface side out, on the contrary, the switching operator 99 is turned counterclockwise. While the nip roller 96B on the take-up side of the roller 76 is allowed to float from the roller 76, the nip roller 96A on the supply side is pressed to the roller 76 by the cam 99C. When the cassette is attached upside down, only either the nip roller 96B on the supply side (or 96A) is always pressed to the roller 76.

Title: Atomizer for low nitrogen oxides combustion
Inventor: SATOU KAZUNORI
IPC: F23C99/00
Filed: 1987-02-20
Abstract: PURPOSE:To make jet streams minute, make possible low NOx combustion caused by variable density combustion, accelerate burning-up, reduce unburnt part in ashes, and make possible combustion with low NOx and high efficiency simultaneously by making the slender ratio of jet holes at both sides larger than that at the center. CONSTITUTION:Jet holes 2 and 3 atomizing fuel are divided into two groups and opened in the furnace side surface of an atomizer chip mainbody 1 and a ceramic-made abrasion resisting tube 5 or 6 is inserted into each hole. The diameter D1 of the mixing jet hole 3 at both ends of each jet hole group is smaller than the diameter D2 of the center mixing jet hole 2 and the length L1 and L2 of both jet holes are the same. As a result, the slender ratio L1/D1 of the holes 3 at both sides is larger than the ratio L2/D2 of the hole 2. At the outer edge of jet streams, atomization is remarkably satisfactory and the mixing of combustion air with fuel is therefore promoted. Dust concentration is reduced without increasing the NOx concentration in exhaust gas and the unburnt content in ash can be reduced.
