Title: Two channel fork-shaped optical gate having fail-safe structure
Inventor: RAINAA SHIEEN
IPC: B66B1/36
Filed: 1991-10-29
Abstract: PURPOSE: To provide a elevator floor detector having a fail-safe structure. CONSTITUTION: A two-channel forked light gate has a cyclical dynamic self- monitoring circuit and is capable of performing preventive failure detection. The cyclical dynamic self-monitoring circuit executes simulation of an actual running sequence by optically short-circuiting the light gate to simulate a state where a switching vane emerges for a short time in the outside of the fail-safe light gate when an elevator car arrives and stops at one floor. But relay power interruption thereby generated is shorter than a relay releasing time and thus the relay is not placed in a released state when no failures occur in the circuit. In case of a failure, the reaction of the safety circuit of a corresponding elevator controller is generated by contact with the relay. A test signal that appears cyclically is a primary control signal for the simulated interruption.

IPC: B32B15/01
Filed: 1994-11-17
Abstract: PURPOSE: To manufacture a titanium clad steel plate having excellent joining strength at a low cost. CONSTITUTION: In this manufacturing method of the titanium clad steel plate by the hot rolling, one or more passes of the rolling of the assembled slab for rolling are executed in the first hot rolling process with the draft of >=15% at 950-1100 deg.C, and one or more passes of the rolling with the draft of >=5% at 90-600 deg.C are executed in the second hot rolling process to manufacture the titanium clad steel plate. The slab may be left in the air down to the temperature of <=900 deg.C after the first hot rolling process, and rolled in the second hot rolling process.

Title: Pressure-joined type semiconductor device
Inventor: KITAGAWA MITSUHIKO
IPC: H01L21/66
Filed: 1989-10-31
Abstract: PURPOSE:To restrain a part of a semiconductor pellet in contact with an electrode member from increasing in heat release value and to improve a semiconductor device in breakdown strength by a method wherein the crystal defect density in a semiconductor pellet surface is so distributed as to shorten the carrier life time of its heat releasing part not in contact with an electrode member compared with that of its part in contact with the electrode member. CONSTITUTION:The whole face of a semiconductor pellet 10 is uniformly irradiated with an electron beam to be low enough in carrier life time, and a semiconductor device is set to nearly a target value in electrical properties. Then, a part of the semiconductor pellet 10 other than a heat releasing part which is in contact with an electrode member 14 and possessed of an sufficient heat-dissipating effect is irradiated with an electron beam in a dose nearly ten times as much as that in which the whole face has been uniformly irradiated. At this point, a part A locally irradiated with an electron beam is low in heat dissipating property but has a crystal defect density 1.5 times or more as large as that of the heat dissipating part of the pellet 10 in contact with the electrode member 14, where the crystal defect density functions as a carrier recombining center. By this setup, the part A irradiated with the electron beam is decreased enough in carrier life time as compared with the heat releasing part in contact with the electrode member 14, so that it is restrained from increasing in heat release value and can be improved in back power resistance at reverse recovery.

Abstract: PURPOSE: To facilitate the attaching/detaching work of a battery by arranging the battery below a basket, supporting the battery by a rear frame, forming an opening in a bottom wall of the basket, and arranging an opening/closing lid on the opening. CONSTITUTION: A battery 52 is arranged below a basket 20 and supported by a rear frame 5 in an attachable/detachable manner, an opening 20b is formed in a bottom wall 20a of the basket 20, and an opening/closing lid 25 is arranged on the opening 20b. To achieve the maintenance, charging or attachment/ detachment of the battery 52 can be achieved only by opening the opening/ closing lid 25 or the basket 20 to improve the workability. Because the upper part of the battery 52 is covered by the basket 20, damages by the external force can be avoided, and because the battery is supported by the rear frame 5 which is heavy in weight, the center of gravity of the whole tricycle body can be lowered more to improve the traveling stability.

Abstract: PURPOSE:To prevent a flogging from being generated on an image carrier and to obtain a high quality picture by providing a such a means that it increases the effective of recovering toner stuck to the image carrier side to the developing sleeve side. CONSTITUTION:When the AC element of a developing bias is in a phase of pi/2, force to pull back toner T toward the developing sleeve 2 act. Conversely, when the AC element of the developing bias is in the phase of 3pi/2, force to pull back the toner T toward a photosensitive body drum 1 acts. Toner is recovered by turning off the AC element of the developing bias and at the same time by maintaining a DC element at +200V over a period equivalent to four cycles. That is, an electric field, whereby the toner T stuck to the photosensitive body drum 1 is pulled back to the developing sleeve 2, is kept intense. Thus, a picture with satisfactory picture quality is always obtained without generating fogging on the image carrier.
