Title: Continuous etching of stainless steel strip and method and apparatus for plating alunimum
Inventor: BOGUDAN ZEGA
IPC: C23C2/02
Filed: 1990-05-18
Abstract: PURPOSE: To improve etching efficiency and the adhesion property of Al films and to reduce the size of the apparatus by directly combining the magnetron plasma etching in a first stage and the immersion coating from an aluminum bath in a second stage.  
     CONSTITUTION: A steel strip 5 is introduced into one end of a long and low- pressure Ar scavenging enclosure 1 and is continuously passed along the passage extremely proximate to one group of plasma magnetron devices 24 so as to be aligned thereto. The steel strip 5 is exposed to the low-pressure Ar plasma magnetron discharge from the devices 24, by which the surfaces of the steel strip 5 are regularly and effectively etched. The etched steel strip 5 is passed off-line through the molten Al bath 3 and is then taken out. The layers of the Al are deposited on the surfaces of the steel strip 5 by immersion coating and are solidified by cooling, by which the thin and uniform Al films having the good adhesion property are formed. The steel strip 5 subjected to the Al plating is taken up.

Title: Method for separating hydrogen cyanide from gas and waste gas
Inventor: YOAHIMU FUITSUSHIYAA
IPC: B01D53/54
Filed: 1992-05-20
Abstract: PURPOSE: To provide a process for separating hydrogen cyanide from gases and waste gases, in which hydrogen cyanide is more quantitatively separated than in well known processes and overdosing with formaldehyde can be surely prevented. CONSTITUTION: An aqueous solution of hydrogen peroxide is added to a measuring stream branched from a washing liquid leaving a gas washer so that free hydrogen peroxide is still detectable after 1-100s contact time. Then the vapor pressure of HCN on the measuring stream thus treated and adjusted to a constant pH value of 2-11 is detected as a measured value.

Title: Chuck
Inventor: KANEDA YOSHIO
IPC: F15B15/08
Filed: 1984-06-20
Abstract: PURPOSE:To reduce the size of an inner chuck in an automatic production machine by holding chuck clicks splitted into two by means of an O-ring through a fulcrum pin. CONSTITUTION:The chuck click 9 is splitted into two but holding a fulcrum pin 7 and continuously opening the tip of the click 9 through the force of an O-ring 6. The piston 8 is pushed up continuously through the force of a compression spring 11. Upon supply of compressed air through an air-hole in the cover 12, the piston 8 will lower to open the chuck click 9 by means of its wedge face or to close the tip section of the chuck click 9 thus to release the work. While upon interruption of compressed air supply, the piston 8 is returned upward through said spring 11 to open the tip section of the chuck click 9 through the force of O-ring 6 thus to grasp the work. Consequently, the size of chuck can be reduced more than half of conventional one thereby it can be used even when the size of chuck is limited because of the conditions of machine.

The whole of the aforesaid fittings is mounted on a fixing foundation 6, thereby enabling the rotation of the mirror part 1 in vertical and horizontal directions via said two motors 3 and 5. The side mirror so constituted can be made estremely small-sized, because the supersonic motors 3 and 5 are thin type. And large torque is available therefrom and the mirror can be directly driven. In addition, the motors 3 and 5 do not rotate at the time of rest and the direction of the mirror is not changed due to an external force.

Inventor: SHIRAKAWA SHINGO
IPC: H01T13/46
Filed: 1989-05-23
Abstract: PURPOSE:To reduce the bending load acting to iron tower arms from the weight of a lightning arrester by inclining the lightning arrester to keep away the high voltage side end of the lightning arrester from the hanging insulator gang and holding the earthing side end to an installing metal.

Abstract: PROBLEM TO BE SOLVED: To obtain a hair-washing composition which gives a good touch, especially extremely excellent finger couxbability, when hair is rinsed, and gives a soft touch without stiffening the hair, when the hair is dried. SOLUTION: This hair-washing composition contains (A) at least one kind of anionic surfactant and (B) a cationic group-containing polymer. Therein, the characteristic comprises that a scattering strength change ratio of inequality I: [dilution I]/[initial period I] in a dilution process until the complex of the polymer with the surfactant is deposited is 1.4 to 2.5, when the composition is diluted with water, or that a scattering strength change ratio of inequality II: [dilution I]/[minimum value I] is further 1,4 to 2.5, when the scattering strength is minimized in the dilution process and further when the scattering strength is increased by the dilution. (In the inequalities I and II, [dilution I] is a relative scattering strength at a dilution ratio just before the deposition is caused by the dilution; [initial period I] is a relative scattering strength before diluted; [minimum value I] is the minimum relative scattering strength, when diluted).

Filed: 1989-05-22
Abstract: PURPOSE:To prevent the malfunctions occurring in a data reading state by providing a floating deletion means which charges or discharges one of paired sense amplifier nodes synchronously with a sense amplifier after a transfer gate is turned off. CONSTITUTION:The transfer gates 53a and 53b consisting of the NMOSs which are turned on and off by a control signal TG are connected between the sense amplifiers 51 and 52. At the same time, a floating deletion means 54 is connected between paired sense amplifier nodes SA. The means 54 is separated from the paired bit lines when the gates 53a and 53b are turned off and charges or discharges one of paired sense amplifier nodes synchronously with the 2nd sense amplifier 52. Then the floating state of the sense amplifier node is deleted when the read data is transferred after a sensing action. Thus the malfunctions occurring in a data reading state can be prevented.

Abstract: PURPOSE:To improve the strength of a bulb near the sealing section and reduce its damage when an end plate and the bulb are sealed by glass frit in a groove provided on the surface of the end plate by forming a storage pool with the flat bottom at the periphery of the opening end of the bulb. CONSTITUTION:A storage pool 11 with the flat bottom formed at the opening end 2 of a bulb 1 is received by a bulb receiving groove 7 of an end plate 3 and is sealed on the end plate 3 by glass frit 8. Consequently, heat capacity is increased. Thus, the temperature difference generated between the bulb 1 of the sealing section and the end plate 3 in the cooling process of the sealing process is reduced and the stress applied to the bulb 1 in the vicinity of the sealing section is also reduced. In addition, since the thickness of the glass for a section 9 to which the shear stress of the bulb 1 of the sealing section is applied is thick, the strength against the shear stress is increased. Accordingly, the strength of the bulb 1 in the vicinity of the sealing section is improved sharply.
