Title: Humidifying unit
Inventor: SHIBATA YOSHIHIKO
IPC: F24F6/04
Filed: 1994-03-29
Abstract: PURPOSE:To prevent mist or white powder from precipitating without retrogradation of the efficiency of a moisture-permeable film by providing a humidifier film comprising a hydrophilic material which can absorb water for humidification, let it migrate, and release it and a hydrophobic porous film which covers the hydrophilic material. CONSTITUTION:A hydrophilic material 3 absorbs water 11 for humidification by capillarity and draws it to a required height. Besides this function, this material functions to let water 11 for humidification migrate and supply it to all parts of the inner sides of a hydrophobic porous film 4. When the humidifier is operated, the hydrophilic material 3 absorbs water and the water which has migrated to the surfaces of the material volatilizes as steam from the surfaces of the hydrophobic porous film 4. For the portion of water having passed off as steam, the humidifier sucks up a new supply of water and lets it migrate, thus functioning to keep itself impregnated to a constant degree. The hydrophobic porous film 4 is permeable to steam and impermeable to water. For this purpose use can be made of a continuous porous material obtained from a synthetic resin.

Title: Printer with controlling mechanism for protruding leading end
Inventor: MIKAMI IZUMI
IPC: B41J11/42
Filed: 1984-04-24
Abstract: PURPOSE:To prevent errors from being generated even when a leading end protruding operation is repeated and prevent misregister of colors from occurring, by monitoring by a detector a leading end protruding position for a printing paper. CONSTITUTION:Since reflected light from a mark 21 is weaker than reflected light from the other part, an output obtained by detecting the former reflected light by a photo-transistor 221 and converting the detection signal into a voltage is lower than a reference voltage (c). The output is compared with the reference voltage (c) by a discriminating circuit 6, and since the voltage (c) is higher, a stopping command is generated in a motor-driving circuit 7. At this position, the number of steps in a pulse motor 8 is reset to zero, and a leading end protruding position is set. Thereafter, printing in the first color 3-a is conducted. After completion of the printing, the printing paper is rewound in the direction of an arrow (b) by a pin tractor 1 driven by a pulse motor or the like, in which case the position-detecting mark 21 of the paper 2 is detected by a sensor 22, whereby closed-loop control is conducted to set the paper to a predetermined leading and protruding position.

Abstract: PURPOSE:To attain high speed test by dividing an area of an AND input line into plural numbers and constituting an area so that a logical value of the product term line at test is made independent of the input data of an input line of other area thereby decreasing the number of combinations of possible input data. CONSTITUTION:Eight AND input lines 1, 1... of a programmable logic array (PLA) are divided into two areas a, b comprising four inputlines 1a-1b, and product term lines 2a, 2b between the divided areas (a) and (b) are made respectively independent. Product term lines 2a, 2a...2b, 2b... are connected respectively to inputs of AND gates c, c... and also to inputs of area selection data selectors d,d.... The selector (d) selects the data of the product term 2a or 2b of the area (a) or (b) by using an area selection signal (e). The number of input patterns is 2n in a conventional PLA when all combinations of the AND input line numbers (n) are tested. In dividing the input lines into two as shown in this example, the number is 2<n/2>X2, the input pattern number is less and the test time is decreased.

Abstract: PURPOSE:To enable making the thickness of the wall of the barrel substantially uniform from the mouth to the bottom by forming the barrel, whose surface is substantially smooth, in a tapered shape with the perimetric length gradually decreased from the bottom to the mouth. CONSTITUTION:A bottle body 1 is composed of a mouth 11, shoulder 12 extending downward therefrom, barrel 13 whose surface is substantially smooth, bottom 14, etc. On the side in the upper part of the bottle body 1 a recession 2 for attaching a handle is formed and at this recession 2 the bottle body 1 is fitted with a handle 3 which is composed of a gripping part 31 and fastening parts 32 formed at the ends thereof. The barrel 13 has a smooth surface free of ribs or the like virtually to its full extent and the barrel 13, substantially being smooth at the surface, is formed in a tapered shape with the perimetric length gradually decreased from the bottom to the mouth. Since the perimetric length, which is smaller in the upper part than in the lower part, makes the wall difficult of being drawn to an excessively thinner wall, the wall can be formed with virtually a uniform thickness from the mouth 11 to the bottom 14; therefore, the wall at the recession 2 for attaching the handle can also be saved from becoming thinner.

Abstract: PURPOSE:To obtain a nonmagnetic sintered hard alloy having excellent hardness, wear resistance and strength and suitable for a cutting tool and mold parts by subjecting the needed member of a substrate having excellent workability which consists of a Ta-Ti-W alloy having specific compsn. to a nitriding treatment. CONSTITUTION:The Ta-Ti-W alloy having the compsn. consisting of, by weight, 35-60% Ti, 10-40% W and the balance constituted of Ta is refined. The alloy is regulated to the matrix, by which the edged region of the cutting tool and the molded parts to which wear resistance is required can be manufactured. The part of the edged region, etc., requiring hardness is subjected to heating, e.g., for 24-48 to 400-600 deg.C in an ammonia gas and to a nitriding treatment in order to improve the hardness of the edged region of a cutting tool, the inner face of a mold, etc., and to improve its wear resistance and corrosion resistance. Since the nitrified region has the hardness and wear resistance higher than a WC-Co sintered hard alloy and has nonmagnetic characteristics, it is suitable as the material of scissors for cutting of a magnetic tape and the mold material for the molding of magnetic powder.
