Title: Ink jet printer
Inventor: INOUE KUNIHIRO
IPC: B41J2/165
Filed: 1987-03-31
Abstract: PURPOSE:To prevent ink from drying, by providing a magnetic fluid layer at the tip of a nozzle section with a thickness thinner than a specific dimension. CONSTITUTION:An ink jet printer is provided at the tip of a nozzle section 3 with a magnetic fluid layer 2 of a thickness thinner than 100mum. Ink 5 subjected to pressure through a piezoelectric element 4 passes through magnetic fluid 2 at the nozzle section 3 and flies in the form of a drop. Normally, the magnetic fluid 2 features saturated vapor pressure of 4.5X10<-4>Torr(30 deg.C) and evaporation rate of 3.25X10<-10>g/cm<2>.sec(60 deg.C). Consequently, variation of weight is less than -7% even after five years(30 deg.C). When the magnetic fluid 2 is arranged at the tip of the nozzle section 3 with a thickness thinner than 100mum, ink is not exposed directly to the atmosphere when the printer is not used, thus protecting ink from drying.

Filed: 1986-04-07
Abstract: PURPOSE:To stably form thick KAu(CN)2 for a long time by using an F-contg. anion exchange membrane of a copolymer consisting of repeating units represented by a prescribed general formula as a diaphragm for electrolysis. CONSTITUTION:A metallic anode 3 contg. gold is placed in the anode chamber 2 of an electrolytic cell 1 provided with a diaphragm 6 and a metallic cathode 5 which is insoluble in an aqueous KCN soln. or the like is placed in the cathode chamber 4. The aqueous KCN soln. or the like is fed and electric current is supplied. An F-contg. anion exchange membrane of a copolymer consisting of repeating units represented by the formula is used as the diaphragm 6. In the formula, X is F or CF3, (l) is 0 or an integer of 1-5, (m) is 0 or 1, (n) is an integer of 1-5, each of (p) and (q) is a positive integer, p/q=2-16, each of R1-R3 is lower alkyl, R4 is H or lower alkyl, Z<-> is a halogen anion and (a) is 2-10. CN ions transferred from the cathode chamber 4 to the anode chamber 2 through the membrane 6 react with gold ions dissolved from the anode 3 and KCN to form KAu(CN)2 in the anode chamber 2. When the concn. of the resulting aqueous KAu(CN)2 soln. is increased to a certain value, the soln. is drawn out of a drawing hole 7 and then Au and an aqueous KCN soln. are newly fed. Thus, KAu(CN)2 can be intermittently formed for a long time.

Inventor: KUSHIDA KOICHI
IPC: B22D11/128
Filed: 1990-03-29
Abstract: PURPOSE:To prevent generation of center porosity and to favorably improve the internal quality of a continuously cast slab by applying larger rolling reduction than unsolidified thickness in this cast slab in the range, which solid phase ratio in the center part of thickness in the cast slab becomes the specific value or higher. CONSTITUTION:In the range, where the solid phase ratio in the center part of thickness in the continuously cast slab is >=0.9, the larger rolling reduction than the unsolidified thickness in this cast slab, is applied. By mutually approaching/separating dies 2a, 2b with rotation of a crank shaft 5, squeezing work is applied to the cast slab strand 1. It is suitable to use the dies having inclined surface O at tip part thereof from where the cast slab strand 1 is received so as not to develop crack on solidified interface in the cast slab strand 1 at the time of applying the squeezing work. As the center porosity exists in almost center part in the cast slab, in the case of continuously casting a bloom, the apparatus having such construction that the prescribed range of the bloom width in center range in width direction can be locally applied with the rolling reduction is favorable.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording apparatus which suppresses generation, adhesion and growth of air bubbles in the passage of the connection member connecting an ink supply source and a printing head by simple constitution to prevent non-ejection of an ink liquid. SOLUTION: A seal member 40 made of rubber is molded by using a mold wherein the roughness of a mold surface for molding the passage wall surface 47 of the seal member 40 is 2.5 μm or less on the basis of the ten-point surface roughness prescribed by JAS B0601 (1994). Since the passage wall surface of the seal member thus molded is smooth, air bubbles are hard to adhere and, therefore, it can be suppressed that air bubles adhere to the passage wall surface 47 of the seal member 40 to grow and the non-ejection of an ink liquid can be prevented.

Title: Square root arithmetic system
Inventor: HIROOKA MASAHARU
IPC: G06G7/20
Filed: 1978-06-29
Abstract: PURPOSE:To remove influence of an analog input signal, by varying the output signal of a multiplier corresponding to an input signal. CONSTITUTION:An analog input signal inputted from the input terminal is supplied to operational amplifier 4 by way of resistance 2. Then, the output signal of operational amplifier 4 is supplied to absolute-value arithmetic unit 7, where its absolute value is calculated. Then, multiplier 8 multiplies the output signal of operational amlifier 4 by the output signal of absolute-value arithmetic unit 7. Therefore, when the output signal of operational amplifier 4 is positive, the output signal of multiplier 8 is also positive and when the output signal of operational amplifier 4 is negative, the output signal of multiplier 8 is negative. The output signal of this multiplier 8 is inputted to operational amplifier 4 via resistance. Therefore, when resistances 2 and 3 are equal each other, the output signal is negative with the input signal positive and is positive with the input signal negative. Consequently, an output signal with the influence of the code of an input signal eliminated can be obtained.
