Title: Manufacture of heat fixing roller
Inventor: KON SHUJI
IPC: F16C13/00
Filed: 1986-07-22
Abstract: PURPOSE:To obtain a high-performance fluororesin-coated heat fixing roller without deteriorating a rubber layer by covering the end surfaces of a core and a bearing part with a heat insulating layer of ceramics and then baking a fluororesin coating film. CONSTITUTION:The rubber layer 3 is formed on the roller core 1 and coated with fluororesin dispersion, which is dried preliminarily to form the fluororesin coating film 4; when this fluororesin coating film 4 is baked, the core end surfaces and bearing part are covered with the heat insulating layer 2 of ceramics and the fluororesin coating film is baked. Here, silicone rubber is suitable as rubber which constitutes the rubber layer 3. Thus, the heat insulating layer 2 made of ceramics covers the core end parts and the fluororesin coating film 4 is baked, so heat conduction from the flanks of the core to the rubber layer 3 is precluded and then the rubber layer 3 is never exposed to high temperature for a long time, thereby preventing the rubber layer 3 from deteriorating thermally.

Title: Frequency detector
Inventor: KOMATSU MASATOSHI
IPC: G01R23/10
Filed: 1991-07-15
Abstract: PURPOSE:To detect a frequency accurately without being affected by a change in terms of time in an offset value which is input by a method wherein the offset value is converted so as to correspond to a digital signal which is input. CONSTITUTION:A digital signal which is input is input to an accumulator 1 and a comparator 5. A divider 4 uses a reset signal J as a trigger; it divides it by the counting value H of a first counter 2 and by the addition signal E of an adder 1; it outputs an offset value F. At the same time, the adder 1 and the counter 2 are reset. The reset signal J is formed in such a way that the comparison value B of the comparator 5 is fed back via a D-FF circuit 6 and a logical-product circuit 3. It is generared at each cycle of an input signal A. Consequently, the offset value F is a mean value which has divided the total sum of cycles of the signal by the time. As soon as the offset value F is output, the detection cycle of a offset value is started. By said operation, the frequency of the signal A can be obtained as the output D of a second counter 7.
