Abstract: PURPOSE:To improve the rigidity of a movable member, to raise a resonance frequency, and to execute stable servo by forming a reinforcing member for improving the rigidity of the movable member integrally under a protruding state from an optical system supporting member positioned at the approximately center of the movable member. CONSTITUTION:An opening 4b to be formed with an outer peripheral part 4c and a cylindrical part (optical system supporting member) 4d of a movable member 4 is partitioned into four with ribs 4a and bulkheads 4e formed from the outer peripheral part 4c to the cylindrical part 4d, and two pairs of inner yokes 7a and 7b are positioned here.

Title: Can lid
Inventor: MURAI HIROYUKI
IPC: B21D51/44
Filed: 1992-07-29
Abstract: PURPOSE:To provide a can lid which can securely open the can even if residual thickness of a cut varies. CONSTITUTION:Since an approximately entire body of a score 3 is swollen upward, flexural strength of the score 3 can be increased. Therefore even when residual thickness of a cut 2 is slightly large, opening is possible without deformation of the score 3, preventing a failure in opening. In addition since a lower face of a pushdown part 6 is engaged with an engaging stage K by pulling up an end of a tab 4, force can be securely transmitted to the cut line 2, so than a failure in opening can be prevented even if the residual thickness of the cut line 2 is slightly large.

IPC: G11B20/10
Filed: 1987-08-13
Abstract: PURPOSE:To prevent a medium defect from being erroneously detected as an address mark by storing a medium defect position beforehand, and prohibiting the detection of the address mark when the instruction to detect the address mark is received and while the present position of a head is coincident with the stored medium defect position. CONSTITUTION:When the medium detect position stored by a defect position storing circuit 1 is coincident with the present position of the head indicated by a head address register 2, a cylinder register 3 and a rotation position detecting circuit 4, a comparing circuit 5 outputs a prohibiting signal 6.

Title: Production of filter
Inventor: ARAKAWA KANJI
IPC: B01D39/00
Filed: 1986-08-29
Abstract: PURPOSE:To narrow the width of a superposed part and also to simplify the registration burying a wire gauze in a resin frame part by molding the resin frame so that the resin frame part is allowed to coincide with a tacking part wherein the prolonged part of the wire gauze is folded on a margin of superposition thereof. CONSTITUTION:A wire gauze 3 is made cylindrical by rounding it and prolonged parts 5 projecting up and down are folded to the inside and tacked to form a filter main body 1. This filter main body 1 is inserted into a molding die and a resin frame 2 is integrally molded into the filter main body 1. Since the filter main body 1 is not made to a cross-sectional shape of round circle by rigidity of the wire gauze even if performing the folding processing, inserting registration is performed while correcting the shape by using a tool for die insertion having same diameter as a die sensor pin made semispherical in the tip. The width of the superposed part of the wire gauze is about half of that in a conventional method.

Filed: 1993-08-17
Abstract: PURPOSE:To prevent a lowering of a quality of a printing by eliminating a backlash of a gear wheel line for driving a platen by executing a reverse sending of a sheet after cutting a sheet by a command through an auto-cutter process and then by executing a regular sending of the sheet. CONSTITUTION:A relationship between a gear 101 and a gear 102, in an ordinary stoppage state, is in a stopped state without a space against a regular rotation direction. After an action of an auto-cutter, the gear 101 rotates by a force by which a sheet 109 is drawn, a backlash occurs between the gear 101 and the gear 102. Then, after the gear 101 is made to return to a predetermined position and more, by making a sheet feeding motor 105 rotate reversely, by making the sheet feeding motor 105 rotate regularly and by making the gear 102 return to a predetermined position, the backlash can be eliminated. By this, it becomes possible to eliminate automatically a backlash generated during an action of the auto-cutter at the sheet feeding gears wheels line, and a generation of a printing failure such as a printing crash and the like can be prevented after an action of the auto-cutter.
