Title: Lower layer etching method
Inventor: MORIYAMA WAKAKO
IPC: H01L21/302
Filed: 1992-06-02
Abstract: PURPOSE:To prevent side etching of a lower layer pattern from being produced and completely remove a deep portion of the lower layer by setting an RF output to a specific value or larger and etching gas pressure to a specific value or smaller as the etching conditions of the lower layer. CONSTITUTION:Upon lower layer etching with a reactive ion etching device, an output of a radio frequency power supply 46 is set to 0.21W/cm<2> or higher, and etching gas pressure in a chamber 4 is set to 0.3Pa or lower. Energy of ion advancing perpendicularly to an article to be etched is increased to improve the directivity of the ion. Further, the pressure of the etching gas is reduced to decrease the frequency of collision among time etching gas molecules, and a rate of ions advancing straightforwardly is increased to improve the directivity of the ions. Hereby, the amount of side etching for a lower layer pattern is reduced and no article to be etched is left behind, so that the pattern is formed with high precision.

Abstract: PURPOSE:To immobilize and hold a large amt. of methane fungus bodies with a device for immersing the entire part of a rotary disk in sewage and executing an anaerobic treatment by utilizing a plate body formed by sintering ground particles of ceramics having a specific grain size to a grained board shape as the rotary disk. CONSTITUTION:The plate body formed by molding and calcining the ground particles of ceramics having 100-1,000mu average grain size to the grained board shape is used as the rotary disk of the device for immersing the entire part of the rotary disk into the sewage and executing the anaerobic treatment. As a result, the surface area to which methane fungi stick increases from several times to several tens times and since the surfaces of the particles are rugged, the adhesive power thereof to the rotary disk increases. The fungus body immobilizing power in the fine pores of the disk body is considerably increased as the rotary disk is a porous ceramic disk. The time for the water activation treatment is thereby extremely shortened.

Title: Fatigue-resistant conductive wire
Inventor: TANABE NOBUO
IPC: H01B7/04
Filed: 1995-06-08
Abstract: PURPOSE: To provide a fatigue-resistant conductive wire in which fatigue resistance characteristics after repeatedly receiving stress can be improved, and of which fatigue life is improved by forming a surface layer part of the conductive wire of copper or aluminum of high purity. CONSTITUTION: A surface layer part of fatigue-resistant conductive wire in a thickness range of 1μm or more is formed of copper or aluminum of high purity of a residual resistance rate RRR of 5000 or more. Because recrystallization is generated even at a room temperature in copper or aluminum of high purity of this class, recrystallization occurs with priority at parts where distortion generated by processing, etc., is large. Distortion is thus eliminated by recrystallization at the surface layer part, and the conductivity wire material achieves self-restoration action to improve its fatigue life. The self-restoration action is affected by balance of distortion formation and accumulation speed and restoration speed (recrystallization rate), where it effectively functions when the restoration speed is more than the formation and accumulation speed.

Abstract: PURPOSE:To accelerate warm-up and to improve safety by providing a detecting means on the carrying path, etc., of a fixing mean and controlling the state of a fixing roller and a heating means by means of the presence of a transfer material. CONSTITUTION:A sheet detecting switch 61 which can detect the presence of a sheet is provided on the upper part of a fixing roller guide 41 to be a carrying path. On the other hand, a sheet detecting switch 65 which can detect the presence of the sheet is provided on the upper part of a scraper 53 to be the carrying path of the sheet. When a control means detects the absence of the sheet by the sheet detecting switches 61 and 65 at the time of turning on a power source, the control means controls the stopping of the rotation of the fixing roller 33 of a fixing device 31, and the turning on of a heater lamp 43 inside the fixing roller 33. In other words, the control means drives the heating means inside the fixing roller 33. Thus, the warm-up is accelerated and the overheating of the transfer material, that is, the jamming of the sheet can be prevented.
