Abstract: PURPOSE:To prevent excessive thermal stress from appearing around support sections of a tank by constituting a supporting apparatus for the tank such that support members mounted in fixed relationship with the tank can be freely slid in horizontal directions in a plane of a top plate of a support bar mounted on a hull. CONSTITUTION:Support bars 4 mounted uprightly in a hold C in integral relationship with a hull member B of a hull A have each a top plate 5 joined with a corresponding support member 2 and receive the entire load of a spherical tank by way of the support members 2. The support member 2 and the top plate 5 of the support bar 4 are joined with each other within a horizontal plane and allows free sliding movement of the support member in horizontal radial directions in response to thermal contraction of a tank body 1 whereas movement of the hull or the like is prevented due to the face that part of a horizontally extending edge 6 is loosely fitted between fitting members. Thus, if the tank body should be subject to thermal contraction, there appears no excessive thermal stress around support sections of the tank.

Abstract: PURPOSE: To enlarge the band of resonance frequency in the case of high-speed access by forming a cover film in the fixing part of an elastic support member inserted into a fixing member to easily and inexpensively increase fastening strength between the support member and the fixing member. CONSTITUTION: One-end parts of plate springs 52a, 52b made of phosphor bronze are immersed in the aqueous solution of triazintyol compound to form a cover film part 71. The part is inserted into a fixing member 53 made by the injection molding of an ABS resin for fixation to enhance the connection strength between the springs 52a, 52b and the member 53. Accordingly, a stress which the member 53 receives from the springs 52a, 52b is relaxed even in the case of high-speed access. Therefore, the elastic denaturation of the connection part between the member 53 and the springs 52a, 52b can be reduced. Accordingly, when the whole of an optical head is vibrated by a linear motor in a tracking direction, a resonance frequency is shifted to a high-frequency region and the margin of a gain is increased, so that the stabilization of tracking control may be achieved.
