Title: Color image forming equipment
Inventor: TANIZAKI JUNICHI
IPC: B41J2/525
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent image disturbances due to contact of a developing device with a photosensitive belt. SOLUTION: A photosensitive belt 1 is passed to a belt drive roller 2, the first transfer roller 23, a cleaning roller 4, and a tension roller 3, roughly forming a triangle. Laser beams are radiated to the photosensitive belt 1 from a laser beam generator 6 and form a static latent image. Any disturbance in an electrostatic latent image and an out-of-focus transfer can be prevented by fixing the first transfer roller 23 and the tension roller 3 to a holding member 36 whose axle 4a of rotation is the pivot of the cleaning roller 4 in a rotatable manner, and making the tension roller 3 horizontally movable.

Abstract: PURPOSE:To facilitate plating and to easily obtain a high-quality plating by successively applying pretreatment such as degreasing, anodic phosphoric acid etching, and cathodic sulfuric acid activation to the surface of a material contg. Ni. CONSTITUTION:The surface of a material having a layer contg. Ni at least on its surface is plated with a metal such as Cr, Ag, Cd, Cu, Ni, and Zn. In this case, degreasing, anodic phosphoric acid etching, and cathodic sulfuric acid activation are successively applied to the surface of the Ni-based material as pretreatment. As the degreasing treatment, the material is vopor-degreased in an org. solvent, and then electrolytically degreased with alkali soln. The anodic phosphoric acid etching can be carried out, for example, in a liq. etchant contg. about 700-750cc/l of phosphoric acid. An electrolyte contg. about 140-170cc/l of sulfuric acid is used for the cathodic sulfuric acid activation. A desired metal plating is applied on the pretreated Ni-based material, and a metal plating layer having excellent adhesive strength can be obtained.

IPC: H04Q9/00
Filed: 1986-09-24
Abstract: PURPOSE:To detect the failure of a timer in a short time by a remote control by using a microcomputer in monitoring the timer operating at the time of a power failure in a distribution line. CONSTITUTION:In inspecting the accuracy of the power failure recognizing timer ZT, for instance, the microcomputer issues an activating signal to a TSZ terminal and a TSY terminal, this timing is outputted synchronously with a system frequency signal and the microcomputer counts the number of clocks of the system frequency until an output is outputted to a CHZ terminal. Namely, when a ZT is defined to be 500ms and the system frequency signal to be 50Hz(20ms), if the microcomputer counts 25 pieces of system frequency clocks, the CHZ is inputted. When this counted value does not coincide or not exist within an allowable range, the microcomputer executes an abnormal processing.

Title: Laser device
Inventor: URISU TSUNEO
IPC: H01S3/1055
Filed: 1986-09-24
Abstract: PURPOSE:To provide a laser having a high spectral purity of output light and a high output by mounting one or more hole plates each having the same number of holes at predetermined position in a resonator, and mounting the hole plates so that optical axes passing the holes between all the plates coincide with a plurality of optical axes of the number of the holes. CONSTITUTION:Hole plates 8, 9, 10, 11 having the same number of holes are mounted at predetermined positions in a laser resonator. In order to narrow the spectral width of an output light, the hole (d) must be reduced, and the output should be thus decreased. In case of K, F excimer lasers, an active region of approx. 10mm X 30mm is easily formed by discharging. Accordingly, a plurality of holes are formed at the hole plates to easily oscillate simultaneously at a plurality of optical axes. In this case, it is necessary to optimize the diameter and the interval of the hole so as not to reduce the spectral purity. The interval between the centers of the holes is set to W + 2di (where W is the extension of the optical beam at the position at a distance L from the hole, and di is the radius of the holel), thereby realizing an optimum configuration, i.e., a configuration in which the number of the axes is maximum.
