摘要:
A process for manufacturing a cold rolled stainless steel strip of high gloss with a high production efficiency by employing a high rolling speed. Mirror-finished work rolls having a Young's modulus exceeding 54,000 kgf/mm2 and a centerline average surface roughness, Ra, not exceeding 0.10 micron are employed for the last of a plurality of successive passes for cold rolling, while the steel to be drawn between the rolls for the last pass has a centerline average surface roughness, Ra, of 0.05 to 0.30 micron.

In a communication network wherein a management station is connected to at least one agent station, an execution request message is first transmitted from the management station to the agent station for requesting it to execute a process. In response, the agent station estimates a length of time taken to execute the process and transmits a first reply message to the management station, and subsequently estimates a length of time remaining to complete the execution of the process. The management station sets a timer according to the length of time contained in the first reply message and starts the timer. When the timer expires, the management station transmits a time request message to the agent station. In response, the agent station transmits a second reply message containing the remaining time. In response to the second reply message, the management station determines that the requested process has been executed if the remaining time is zero. If the remaining time is nonzero, the management station sets the timer according to the second reply message, starts it and determines that the requested process has been executed when the timer expires.

An electrophotographic photosensitive element having S-type photo-induced potential decay characteristics and an electrophotographic apparatus using the photosensitive member are provided.The photosensitive member comprises a charge generation layer and a charge transport layer on an electroconductive substrate. The charge transport layer contains a polymer in a phase separated state with a modulated structure, comprising an electrically inactive phase and a charge transporting phase. The amount of exposure required for 50% potential decay is less than 5 times the exposure amount required for 10% potential decay. The modulated structure includes, for example, a mixture of insulating polymer and charge transporting polymer and the like. The modulated structure can be formed by the method of separating a homogeneous phase of these polymers into two phases.

A cassette tape player utilizes a tape cassette having apertures formed through one side wall of its casing to accept a magnetic head and a pinch roller. The cassette tape player has a body assembly on which the tape cassette is freely loaded or unloaded and a lid supported by the body assembly so as to be freely rotatable for closing and opening the cassette tape player. The tape cassette is inserted into a loading region of the body assembly by closing the lid. A head assembly chassis is supported by one side end portion of the cassette loading portion so that its moves together with the lid. The head assembly also supports a magnetic head holder and the pinch roller. The tape cassette is supported by securing the upper surface wall of the cassette casing by inserting cassette holding members into the pinch roller insertion openings of the tape cassette. These holding members which are substantially parallel to the inner top wall of the lid support one side of the upper surface wall of the tape cassette while spring members provide opposing pressure to the opposite side of the upper surface wall of the tape cassette. The holding member and spring member combination hold the tape cassette for loading in a compact arrangement to ensure efficient use of space in the cassette tape player.
摘要:
Microwaves supplied from a magnetron through a waveguide are resonated in a cavity resonator to increase their amplitude. The resonated microwaves are emitted into a plasma production chamber through slits and a wall. Then plasma is produced in the plasma production chamber into which plasma processing gas is introduced. The plasma is employed for uniformly processing a substrate.

An optical connector includes a plug and an adaptor to which the plug is to be connected. The adaptor is formed with a plug body fitting portion and a holder fitting portion. The plug has a plug body to which a optical fiber cable is fixed. A floating holder is arranged in the plug body to be movable in any direction with respect to the plug body. An end of the optical fiber of the cable is attached to a ferrule which is supported by the holder. When the plug is connected to the adaptor, the plug body is fitted to the plug body fitting portion and the holder to the holder fitting portion. At this time, the plug body is locked to the plug body fitting portion by a lock mechanism, and the holder is locked to the holder fitting portion by engaging projections on the holder and engaging holes which are formed in the holder fitting portion and engaged with the projections.
