Abstract: PURPOSE:To conveniently form a thick hardened layer on the surface of a Ti material by applying a hardening agent obtained by mixing the powders of Cr, Mn, Fe, Co and Ni and a resin soln. on the surface of Ti and heating the material to diffuse the metal element into Ti. CONSTITUTION:One kind among the powders of Cr, Mn, Fe, Co and Ni having <=50mum grain size in the case of a globule or <=200mum grain size in the case of a flake and a soln. of an acrylic resin, etc., are mixed to prepare a surface hardening agent. The agent is applied on the surface of Ti or a Ti alloy. The material is heated in vacuum at a temp. higher than 800 deg.C and lower than the eutectic temp. of the metal in the agent and Ti to diffuse the metal element into the Ti or Ti alloy. The material is hardened, as required, after diffusion or age-hardened to adjust the surface hardness. Consequently, the hardness of the surface of the Ti material is controlled to about 400-600Hv without need for intricate pretreatment.

IPC: G11B7/085
Filed: 1989-03-30
Abstract: PURPOSE:To suppress an optical beam spot to exceed an objective position when an optical head is braked and to realize an exact track access in a short time by deviating the control operating point of a precise moving means in a moving direction from a neutral position during track access operation. CONSTITUTION:In a track access system equipped with a coarse moving means 5 and a fine moving means 4a, when the coarse moving means 5 executes the access operation, the control operating point of the fine moving means 4b is held in a state that the above point is deviated from the neutral position. Even when the optical beam spot exceeds the objective position by the enertia force of an optical head 4 at the time of finding the access operation of the means 5, above spot does not exceed the neutral position by the means 4b at this time point because the position is preceded by the position of beam spot preliminarily, or even it if exceeds the neutral position the distance to the neutral position is short, so that the control by the means 4b can be realized in a short time.

Title: Vertical magnetic signal processing system
Inventor: FURUKAWA TERUO
IPC: G11B5/58
Filed: 1984-04-18
Abstract: PURPOSE:To reduce the crosstalk and also to improve the track density by decreasing both the width and the thickness of a track of the 1st main magnetic pole in the width and the traveling directions of said track respectively in comparison with those of a track of the 2nd magnetic pole. CONSTITUTION:A tracking signal of a low frequency is recorded in the track width direction of an SP head H by the 2nd magnetic pole 2a having large width. While a main signal of a high frequency is recorded to tracks 3a, 3b,... respectively by the 1st main magnetic pole 1a. Then an end or both ends 5a, 5b,... of tracks 3a, 3b,... where the main signal is recorded are erased by the tracking signal. This eliminates a gurd band as well as the effect of the crosstalk. At the same time, the lengthwise thickness of the track of the pole 2a is increased. As a result, no main signal is reproduced on a track by the pole 2a and only the tracking signal can be reproduced when the information recorded on a track is reproduced.

Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To improve the sliding property with a cylinder while forming a piston of resin, and improve the heat insulating property and abrasion resistance by using for a part of a thermo setting resin forming the piston a double functional phenol component. SOLUTION: A phenol resin including double-functioning phenol component, graphite and carbon fibers are mixed at the predetermined ratio, and molded so as to obtain a piston 1 without providing a rider ring.
