Title: Metal surface treating agent
Inventor: HIRAO KUNIO
IPC: C23G1/10
Filed: 1978-05-18
Abstract: PURPOSE:To provide a surface treating agent capable of treating ferrous and nonferrous metals uniformly and having degreasing power by adding boric acid or a borate and a surfactant to sodium hydrogensulfate or potassium hydrogensulfate. CONSTITUTION:To an about 4 wt% aq. soln. of sodium hydrogensulfate or potassium hydrogensulfate are added about 0.5-4% of boric acid or a borate and about 0.5-4% of a surfactant. Using the resulting metal treating agent, steel, copper alloy, zinc alloy or the like is treated at about 60 deg.C for about 10 min. This agent scarcely induces hydrogen embrittlement in steel and can treat fats and oils, so it improves a surface treating process. In addn., the agent controls oxidation of the treated material and thus also acts as a rust inhibitor.

Title: Wheel balancer employing phasic display system by light beam
Inventor: NAGURA YOSHIHIKO
IPC: G01M1/08
Filed: 1980-05-08
Abstract: PURPOSE:To improve workability and accuracy by a method wherein the phase of unbalance is stored, and after measurement and the wheel has stopped, a signal is outputted at the weight attaching position. CONSTITUTION:A wheel 12 is mounted on a spindle 4 and rotated by operating a motor 10, through a transmission member 9. An up/down counter 19 is reset by using the pulse generated once every turn of the wheel 12 in synchronization with the phase of unbalance. When a switch S2 is turned off after measurement has been completed, a rotary encoder 11 and the up/down counter 19 have memorized the phase of unbalance. Therefore, if the wheel 12 is manually rotated to the position at which a beam projecting lamp 3 is turned on, the zero position of the up/down counter 19 sholud be reached. This shows the phase of unbalance.

Filed: 1982-04-10
Abstract: PURPOSE:To enable high-density recording and to provide sufficient weather resistance and head crush resistance, by successively forming a chromium oxide film having <=20nm thickness and an SiO2 film having <=30nm thickness as protective films on a metallic magnetic thin film. CONSTITUTION:A metallic magnetic thin film 2 is formed on a substrate 1, and a chromium oxide film 3 having <=20nm thickness and an SiO2 film 4 having <=30nm thickness are successively formed on the film 2. The film 3 has superior weather resistance, and the film 4 has superior head crush resistance. Since the total thickness of the films 3, 4 is as small as <=50nm, highdensity recording is enabled. For example, an Ni-Co-P film having 50nm thickness is formed on a substrate for a disk by electroless plating and dried. The substrate is placed in a sputtering chamber, and RF sputtering is carried out by using a chromium plate having 100mm. diameter as a target electrode in an oxygen atmosphere under 1-5Pa pressure for a time corresponding to the desired thickness. An SiO2 film having the desired thickness is then formed by sputtering using an SiO2 plate as a target in an Ar atmosphere.

Filed: 1986-03-20
Abstract: PURPOSE:To suppress the neck-in and consequently to improve the product quality and production efficiency by a method wherein the side edges of a film are extended by means of local rotary flowing action and film sticking action. CONSTITUTION:Deckel holders 2, each of which contains an exterior type deckel 2a, are fixed at the tip parts of the lip 1a of a die 1. A rotary deckel 4 is arranged at the tip of the deckel holder 2 in such a manner that the peripheral surface contacts with the side edge of a resin film A. The diameter (d) and width (w) of the rotary deckel, the distance (l) between the center of the rotary deckel and the die lip and the like are determined on the basis of the molecular weight and viscoelasticity of resin, the resin output through the extruder die, an air gap, processing speed and the like. The side edges of the resin film A extruded through the die is, at first, extended by the exterior type deckel 2a and then extended again by the rotary flowing action produced between the film and the rotary deckel. Thus, the resin film A is extended in the state that the side ends of the extruded resin film are locally flowed rotarily in the width direction of the resin film. Consequently, the neck-in of the resin film A is suppressed.
