Title: Twin drum type strip continuous casting device
Inventor: ARAI TAKASHI
IPC: B22D11/06
Filed: 1992-02-28
Abstract: PURPOSE:To repair a dimple in a drum without lowering the productivity and before producing a bad cast strip when the dimple formed in the drum wears in a twin drum type strip continuous casting device. CONSTITUTION:When a part of the dimples formed on the cylindrical surfaces of the casting drums 2, 3 wears, since gas film is not formed between solidified shell 7 formed in a molten metal pouring basin part 6 and the drum, the solidified shell is brought into direct contact with the cylindrical surface and by making the drum good thermal conductivity, the temp. of the cast strip 8 is lowered. Therefore, in the part where the detected value by cast strip detecting devices 13, 14 for measuring the surface temp. of the cast strip 8 abnormally is lowered, the dimple at the specific part on the cylindrical surfaces of the casting drums 2, 3 corresponding to the above part is worn. Then, by working a controller 12 when the specific part on the cylindrical surface comes to the position faced to the shot blaster 10, 11, the dimple is again formed to the part where the dimple is worn. This repairing is executed while containing an original casting operation.

Abstract: PURPOSE:To prevent a dryer from being brought into operation with a drum cover open by a method wherein a shield member is mounted so as to shield a to-be-detected element when the drum cover is in such a state that it closes an opening of a drum, and the open or clos state of the drum cover is judged according to the detected signal of a detection means. CONSTITUTION:After start-up of operation, the open or close state of a drum cover 21 is judged according to detected signal of a drum cover position detection means 31, and a buzzer, for example, is sounded and the operation is stopped when the drum cover 21 is in open state, so that a dryer is prevented from being brought in operation with the drum cover 21 open. Especially in this case, as a lead switch 29 is arranged on a main body 20 so that it is a little apart toward the rotating direction side from the position of the to-be- detected element when the drum cover 21 is in full open state at the drum stop position, the open state of the drum cover 21 is judged immediately after operation starts in case the drum cover 21 is in full open state. On the other hand, the open state of the drum cover is judged when the drum 16 is turned a little after operation starts in case the opening degree of the drum cover 21 is a little.

Title: Id blade
Inventor: TAKAHASHI MASARU
IPC: B24D3/00
Filed: 1987-02-26
Abstract: PURPOSE:To minimize warp or saw mark of an ID blade and to ensure cutting quality by jointing an electrodeposition diamond abrasive grain layer having predetermined cutter depth to the inner circumferential edge of a galvanized metal layer having predetermined depth which covers circular inner circumferential section of a core metal. CONSTITUTION:A galvanized metal layer 23 having depth reducing gradually toward the outer circumferential direction of an ID blade covers circular inner circumferential section of a core metal 1. A diamond abrasive grain layer 24 having predetermined depth is deposited onto the inner circumferential edge of the galvanized metal layer 23 to prepare a desired ID blade. Here, the metal layer 23 is homogeneous and there is no local point on both side faces where the stress is not uniform, thereby ID blade does not bend nor warp and insufficient cutting quality can be avoided. Furthermore, since the metal layer 23 and the abrasive grain layer 24 are narrow,contacting area of cutting material with cutting face is reduced thereby unnecessary friction is reduced and occurrence of saw mark can be suppressed.

IPC: G03G15/02
Filed: 1995-03-03
Abstract: PURPOSE: To uniformly discharge electricity onto a body to electrified and to obtain an image with uniform density and without unevenness as a whole image by forming a flexible sheet consisting of an inner layer of a low electric resistance, and mid-layer of a high resistance and a surface layer having lower resistance then that of the mid-layer. CONSTITUTION: The electrifying roller 1 consists of a laminated flexible sheet 2 like a seamless tube and a metal shaft penetrating through the sheet 2. Electricity is fed to the flexible sheet 2 from the metal shaft 3 via flange roller 4 and rubber ring 5, and the sheet 2 has a three-layered structure consisting of an inner layer 2a, a mid-layer 2b and a surface layer 2c. Here the mid-layer is a high-resistance layer and is usually preferred to have a volume resistivity within the range of 10<7> -10<10> Ω, while the surface layer 2c is a layer of lower resistance than the mid-layer 2b, and especially it is preferable for the surface layer to have a resistance equal to or higher than that of the inne layer 2a. Thus, a certain voltage is stably supplied via the inner layer 2a and a constant and uniform electric discharge is secured from the sheet 2. Also, the mid-layer is a layer of the highest resistance and mitigates the electric discharge onto the electrified body from the sheet 2.
