Title: Image forming device
Inventor: SUGIHARA KAZUYUKI
IPC: G03G21/00
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of preventing a failure such as the dropping of a developing unit due to inadvertent pulling out by an operator by connecting the developing unit and an image forming device body with such a length of removable chain as permits the developing unit to be pulled out from the device body only halfway. SOLUTION: A U-shaped hook 202 is provided on one end of a chain 201 fixed on the front side of a printer body by a screw member 200 on the other end. The hook is caught on a front supporting plate, in a state where the revolver developing unit is housed in the printer body. During the operation of pulling out the revolver developing unit, the chain 201 is stretched in the state where the developing unit is supported by the printer body and the movement of the developing unit is transiently stopped. At this time, the hook is removed to completely pull out the developing unit. By such a constitution, the failure such as the inadvertent dropping of the developing unit caused by the fact that the operator pulls out the developing unit with his or her momentum is prevented.

Inventor: ITO MASAKI
IPC: G11B7/2433
Filed: 1986-12-16
Abstract: PURPOSE:To improve weatherbility, sensitivity and signal quality, by providing a recording film composed of a composite film on a substrate, and constituting the composite film of a film based on tellurium, selenium and nitrogen, and a film based on tellurium, selenium, nitrogen and oxygen as the surface layer of said film. CONSTITUTION:A recording layer 21 is provided on a substrate 1 and recording laser beam is allowed to irradiate the recording layer 21 through the substrate 1 while condensed thereto to form pits 22. As the substrate 1, a synthetic resin such as polycarbonate or an epoxy resin or glass is used and guide grooves are provided to the substrate 1 so as to record the pits in a concentrically circular or spiral form at a definite interval with good accuracy. The recording layer 21 is constituted of a composite film consisting of a film based on tellurium, selenium and nitrogen, and a film based on tellulium, selenium and nitrogen formed by forcibly oxidizing the surface layer of said film. By this method, weatherability becomes good, sensitivity is enhanced and signal quality becomes good. Forcible oxidation may be performed by any method (e.g., plasma oxidation) but the irradiation of ultraviolet rays in an oxidative atmosphere is desirable because of good controllability.

Title: Method for removing surface deposit in boron infiltration
Inventor: ARIMA ITSUO
IPC: B08B3/08
Filed: 1988-11-30
Abstract: PURPOSE:To effectively remove the deposit on the surface of a material to be treated by forming a boride layer on the surface of the material, dipping the material in the hot water wherein high-hardness grains are dispersed and circulated, and allowing the grains to collide with the surface of the material. CONSTITUTION:A material 3 to be treated is dipped in a borax bath to diffuse and infiltrate boron into the material, and a high-hardness boride layer is formed. The material 3 is dipped in the hot water 1 wherein high-hardness grains 8 are dispersed in a cleaning vessel 2. A heater 4 is energized to heat the hot water 1 to cause convection. Heating is continued to boil the hot water 1, and hence the grains 8 dispersed in the hot water 1 are circulated in the hot water 1 by steam bubbles 7, and allowed to collide with the surface of the material 3. The deposit firmly stuck to the surface of the material 3 is released by the impact force, and eluted into the hot water 1. Consequently, the clean surface is exposed. The oxides of Al, Ti, Cr, Ni, Co, Ce, Mg, and Zr insoluble in the hot water 1 and having >=2Mohs hardness are used for the grains 8 to be dispersed in the hot water 1.

Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent both the illegal conduct of embezzlement of an operator except a store manager, etc., and the loss of credit of customers, for instance when a 'goods return function' can not be carried out because there is no key that switches to an MGR mode which displays a function that inhibits the execution performed by an operator except a store manager, e.g. about a prescribed function so that an offer of a customer can not be coped with. SOLUTION: A temporary release request of the inhibition of execution that is performed about a 'goods return function' whose execution is inhibited by an operator except a store manager, etc., is recognized (step S6), the operation is specified and also whether he is an appropriate operator is identified (steps S7 and S8), the information of the identified operator is recorded (step S9), the execution inhibition which is performed by the operator except the store manager, etc., about the 'goods return function' is temporarily released to be executable and the executed content is also recorded (step S10). Thereby, it is possible to prevent both the illegal conduct of embezzlement, etc., by the operator and the loss of credit of customers.
