Title: Method for controlling temperature of heat fixing device
Inventor: MORI SHIGENORI
IPC: G03G15/20
Filed: 1984-06-27
Abstract: PURPOSE:To prevent the thermal deterioration of a heat fixing device owing to overshoot by keeping a heat source off during the time since the temp. of the heat fixing device attains the prescribed temp. lower than a preset temp. until said temp. exceeds the preset temp. and decreases again to the set temp. CONSTITUTION:A comparator 22 compares a signal Sr and the signal S corresponding to the surface temp. T of a roller 12 outputted from a temp. sensor 23 and outputs a signal ''0'' when the signal Sr is larger than the signal S. The comparator outputs a signal ''1'' and applies the same to a CPU20 when said signal is smaller. A comparator 24 compares similarly the signal Ss corresponding to the set temp. Ts and the output signal S of the sensor 23 and applies the same to the CPU20. The CPU20 controls the temp. of the heat fixing device 10 in accordance with the compared output ''0'' or ''1'' from the comparators 22 and 24. The heat fixing device is thereby stopped before the surface temp. of the roller attains the set temp. The thermal deterioration of the release layer on the roller surface and stripping pawl powing to the overshoot is thus prevented.

Title: Ecl/cml emitter follower current switch circuit
Inventor: JIYURIO AARU ESUTORAADA
IPC: H03K19/086
Filed: 1990-05-24
Abstract: PURPOSE: To improve a switching speed by interrupting a real emitter-follower(E- F) transistor(TR) element and a real output terminal from an output current sink when the real output terminal is in a high potential state. CONSTITUTION: When a high potential output signal is impressed to an actual output terminal OUT, a low potential output signal appears on a complementary output terminal OUTN, the low potential signal from the terminal OUTN supplies a control signal through a diode D2 in a 1st cross control circuit and a control circuit current sink 16 holds a 1st current switch TR element Q6 in an off state. Thereby an actual output E-F TR element Q4 for supplying a current to the terminal OUT to maintain the high potential level of the terminal OUT is interrupted from an output current sink 14. Consequently, a high switching speed can be attained on the actual output terminal OUT in a transition period from low potential to high potential.

Inventor: SUGIYAMA TOKUHIDE
IPC: C09D127/12
Filed: 1993-05-11
Abstract: PURPOSE:To obtain a water-repellent oil-repellent composition which can stably show excellent water repellency and oil repellency and is excellent in film- forming properties and durability by mixing a specified fluororesin with a fluoropolymer having a polyfluoroalkyl group. CONSTITUTION:The composition comprises 1-95wt.% fluororesin having a fluorocycloaliphatic structure in the main chain and 99-5wt.% fluoropolymer having a polyfluoroalkyl group. It is desirable that the fluororesin is a polymer having a ring structure in the main chain, and a polymer having at least 20mol% ring structure is desirable from the viewpoints of transparency, mechanical properties, etc. The molecular weight of the fluororesin is desirably 0.01-3.0dl/g in terms of an intrinsic viscosity. When this viscosity is excessively small, the film-forming properties are poor, whereas, when it is excessively large, the solubility in solvent is poor. When this composition is applied to leather articles such as shoes and bags, it is effective to give excellent water repellency and oil repellency thereto and to make them proof against the penetration of rainwater in a rainy day and has a persistent excellent effect.
