Title: Manufacture of deformed steel wire
Inventor: KOKITA HIDEO
IPC: C21D8/06
Filed: 1977-12-12
Abstract: PURPOSE:To uniform the cross-sectional hardness distribution of a deformed steel wire by directly patenting each of deformed carbon steel products in a warm water vessel of above 70 deg.C, followed by continuous cold drawing through deformed dies. CONSTITUTION:Each of carbon steel products contg. C; 0.1-0.9%, Mn; 0.5- 0.8% and Si; 0.2-0.3% is deformed to a shape other than round. The resulting carbon steel wire the cross section of which is deformed is patented in a warm water vessel of above 70 deg.C to provide drawability, pickled, and continuously cold drawn through dies of the same shape. Since deformation of the wire in the dies is uniformed, a local increase in friction is minimized on the contact face between the dies and the wire, and seizing or wear of the dies are reduced, elongating the dies life. The uniform deformation results in uniform cross-sectional hardness distribution of the deformed steel wire.

IPC: G11B7/24015
Filed: 1990-06-06
Abstract: PURPOSE:To suppress double refraction to be generated by stress due to screwing by superposing three disks having respectively different diameters and arranging a contact face between a hub member and a disk base in the vicinity of a center hole. CONSTITUTION:The hub members 5, 5 are constituted of cutting the insides of respective flange parts 7 so as to previously leaving proper ring-like step parts 9 on respective boss parts 6 and forming slight gaps 10 between the outsides of respective disk bases 1 and the insides of the flange parts 7. Namely, three disks having respectively different radiuses are concentrically stacked in the descending order and a concentrical hole is formed on the center part. Thus, a pair of hub members 5 are constituted of cutting off the size of the fixing face to be attached to a turn table, i.e. a part exposed to the outsides of the disk bases 1 so as to leave a part close to the center hole as much as possible and forming gaps between the insides of the flange parts 7 and outsides of the disk bases 1. Consequently, the generation of stress due to the clamping force of a screw is deviated from the recording area of each disk base and the influence of double refraction due to the stress can be suppressed.

Filed: 1978-11-30
Abstract: PURPOSE:To make unnecessary the reset time by enabling the use of repetition, through the opposite directional series connection of two charge integration elements to either of which charge is stored and selection of the direction of current flowing to the elements. CONSTITUTION:When the switch 2 is ON with the switch 11 selected to A-A', current flows via the resistor 3 from the power supply 1. In the switch 11, the loop current of C-A-B'-41-42-B-A'-C' flows. The charge integration element 41 to which charge is stored gradually discharges (the element 42 is gradually charged) and when the discharge is finished, the impedance between C-C' is increased. Current flows to the transistor 5, transistor 8 turns on via the resistor 6, and light emitting diode 10 illuminates. When the switch 11 is selected from A-A' to B-B', the state of charge of the elements 41 and 42 are replaced. Since the charge reciprocates between the elements 41 and 42, entirely the same timer time can be obtained.

Filed: 1983-08-18
Abstract: PURPOSE:To prevent satisfactorily scattering of a toner particle of a toner image by irradiating the rear side of a photosensitive body by an auxiliary lamp for transfer use, in a part where the toner image on the photosensitive body and a copying paper are overlapped. CONSTITUTION:A transfer auxiliary lamp 12 and a light shielding plate 13 are placed on the rear side of a photosensitive body 4 of the upstream side of a transfer device 9. In this state, immediately before a toner image on the photosensitive body 4 and a copying form 7 are overlapped, the photosensitive body 4 is irradiated from the rear side, and a latent image potential under the toner image is dropped. When the potential has been dropped, no toner scatters since the toner image is overlapped on the copying form 7. Also, before they are overlapped, the irradiation is prevented by the light shielding plate 13. Therefore, scattering of the toner is prevented, a drop of a picture density and a disorder of a picture are eliminated, and a distinct picture is obtained.
