Title: Method for controlling temperature of fixing device
Inventor: TAMAOKI JUNICHI
IPC: G05D23/19
Filed: 1987-09-28
Abstract: PURPOSE:To prevent low temperature offset from being generated by adjusting a heating preset temperature at a waiting time after completing a warm-up operation by estimating the steep drop of a temperature at a part not being heated by alternate conduction immediately after starting a copying operation. CONSTITUTION:At least either the heating preset temperature set by a first heating means 26 which heats mainly the center part in an axial direction of the upper fixing roller 1 of a pair f fixing rollers 1 and 2 or the heating preset temperature set by a second heating means 31 which heats mainly both end parts in the axial direction is set higher than that set by both heating means 26 and 31 in the copying operation. And after heating by respective heating preset temperature, the temperature is switched to the heating preset temperature in the copying operation by a signal to start the copying operation. In such a way, it is possible to prevent picture quality from being lowered due to the generation of nonuniformity in the glossiness of an image to be fixed and to prevent the low temperature offset at a low temperature part from being generated.

Title: Clock extract circuit
Inventor: IKEDA KIYOSHI
IPC: H04L7/10
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To extract a clock with small jitter by giving a prescribed signal to an OR gate and giving a signal with a repetitive period of '1', '0' of an outputted preamble signal to its own timing regeneration circuit. SOLUTION: A 1st bit of a preamble signal being an output of an OR gate circuit 20 via a 2-time slot delay circuit 21 is set. Then after the lapse of 2-time slot time, a set bit of the preamble signal and the rising of an output signal of the delay circuit 21 are simultaneously given to the OR gate 20. When a received burst signal is at a data period B, a preamble extract circuit 30 does not provide an output and the circuit 20 receives only an input of the preamble signal '1' or '0' that is an output of the circuit 20 itself in 2-time-slot before via the delay circuit 21, and the circuit 20 provides an output. Then the preamble signal '1' or '0' outputted by the circuit 20 itself in 2-time-slot before is given repetitively to a passive resonance type timing circuit 10.

Title: Preparation of flat and fine resin powder
Inventor: TAKAGISHI IKUO
IPC: A61K8/00
Filed: 1985-10-31
Abstract: PURPOSE:To obtain flat and fine resin powder easily at a low cost, by pressing and/or applying shearing force to a resin powder, whose diameter is smaller than a specified value, in a solvent. CONSTITUTION:It is required that the diameter of the resin powder to be used is smaller than 150mum. If the diameter is larger than 150mum, the diameter of the flat and fine resin powder will become larger than 200mum. The kind of the solvent is not limited as far as the solvent does not dissolve the resin powder. Either one or a mixture of more than two types of solvents can be used. The quantity of the solvent to be used is a level just wetting the resin powder and three - ten times of the wt. of the resin powder is preferable. If wetting of the solvent to the resin powder is poor and a homogeneous dispersion can not be achieved, adding an additive such as a surface active agent, etc. is allowable. If the pressing and/or the shearing forces are too strong or too weak, the resin power is ground or the flat power can not be obtained respectively. An appropriate range of the forces should be therefore selected.

Title: Reactive ion etching method
Inventor: TAKIGUCHI KOJI
IPC: C23F4/00
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To allow stable and fast etching continuously by allowing a reactive product which suppresses disappearance of etching seed on the inside wall surface of a reactive device to stick to the inside wall surface. SOLUTION: A material 3 which is to be etched and a single crystal silicon substrate are carried into a load lock chamber 11. When a vacuum chamber 1 and the load lock chamber 11 reach a specified vacuum level, a gate valve 13 is opened. Then the single crystal silicon substrate in the load lock chamber 11 is transferred over a lower electrode 2 in the vacuum chamber 1, and the gate valve 13 is closed. Then a gas guiding valve 10 is opened for introducing an etching gas. After etching with HBr gas and O2 gas introduced, only the flow rate of O2 gas is reduced for etching. Thus, a substance produced at etching of the single crystal silicon substrate sticks to the inside wall surface of reactive device, and increases the amount of etching seed on the inside wall surface.

Title: Production of polyamide biaxially stretched film
Inventor: WATANABE JUNKICHI
IPC: B29L7/00
Filed: 1990-09-14
Abstract: PURPOSE:To enhance flat properties by stretching and thermally-fixing a film and thereafter controlling temp. and moisture content in a slow cooling stage. CONSTITUTION:After a polyamide film is biaxially stretched, it is thermally fixed so that the shrinkage factor in hot water at 100 deg.C is regulated to <=3% in the longitudinal direction and the lateral direction. Thereafter while continuously blowing humidified air at <=150 deg.C, this film is slowly cooled at the rate of <=80 deg.C/sec. Simultaneously humidity conditioning is performed for the film and the moisture content of the film is regulated to 0.5-2%. Thereafter the polyamide biaxially stretched film is produced by winding the said film. In such a way, generation of a curl, a sagging and a wrinkle, etc., due to moisture absorption is reduced in the humudity-conditioned film.
