Title: Fluororubber composition containing fine silicone rubber particle
Inventor: ADACHI HIROAKI
IPC: C08L87/00
Filed: 1988-03-24
Abstract: PURPOSE:To obtain a composition of improved low-temperature property without detriment to the excellent heat resistance and oil resistance inherent in fluororubber, by mixing a fluororubber with specified silicone rubber particles. CONSTITUTION:This composition comprises 50-95wt.% fluororubber (A) and 50-5wt.% silicone rubber particles (B) of a cyclohexane-insoluble content >=30wt.% and a mean particle diameter <=10mum. Said fluororubber used as component A is a highly fluorinated elastic polymer and is exemplified by a copolymer of vinylidene fluoride with another fluorinated olefin. When the content of said cyclohexane-insolubles is below 30wt.%, the object cannot be fully accomplished because the silicone particles grow coarser by agglomeration during drying, kneading, etc., and it is difficult to homogeneously disperse the fine silicone particles in the composition.

A bit rate detection circuit 28 generates a voltage in response to a bit rate of an output signal of the preamplifier 26. Since a resistance of a variable resistive element 25 varies with a voltage applied thereto and a feedback quantity of the preamplifier 26 is changed, the band width and the gain result in a change. The peak detection circuit 29 detects a level fluctuation attended with a gain change based on the peak of the output signal and gives the result of detection to a gain control terminal of the main amplifier 27. The main amplifier 27 controls the level of the output signal to be made constant input terminal the signal given to the gain control terminal.

IPC: G01H17/00
Filed: 1987-03-27
Abstract: PURPOSE:To continuously compute axial torsional vibrations and to prevent a blind sector from being formed by providing plural storage means for storing temporally torque detected values between a torque detector and an axial torsional vibration arithmetic unit. CONSTITUTION:The torque signal storage device 18 which consists of storage means 10 and 11 for storing torque detected values is provided between a electric torque detector 16 which detects the torque of an electric motor 1 and an axial torsion arithmetic unit 19. The data stored in those storage means 10 and 11 are read out alternately through a switch 14 and inputted to the axial torsion arithmetic unit 19. This arithmetic unit 19 uses those data to solve the motion equation of a rotary shaft system, thereby calculating axial torsional vibrations. Consequently, even if a 2nd disturbance data is inputted while the axial torsional vibrations are calculated by using the data from the 1st storage means 10, it can be stored in a 2nd storage means, so a blind sector is prevented from being generated.

Title: Detector for abnormality of heat control system
Inventor: OKANO HIROSHI
IPC: G05B23/02
Filed: 1980-05-27
Abstract: PURPOSE:To detect abnormality with a high precision to prevent the occurrence of secondary disaster such as a fire, by applying a test signal to an operational amplifier and by detecting the test signal from the feedback signal of a heat sensor to discriminate whether the circuit is normal or not. CONSTITUTION:When a test signal (c) is applied to an operational amplifier 1 within a range where a heat control system is not influenced badly, the amplifier 1 not only adds an instruction signal (a) and the test signal (c) but also subtracts a feedback signal (d), and the output is subjected to power amplification in 2 and is supplied to a heating body 4. A heat sensor 5 detects the heating value of the heating body 4 and outputs the feedback signal (d). Thus, the heat control system constitutes a closed loop to perform the heat control in accordance with the instruction signal (a). At this time, the feedback signal (d) includes the test signal (c), and a test signal detector 7 outputs an abnormality signal (e) when the test signal (c) is not detected. Consequently, it is discrimiated whether the heat control system is normal or not by this constitution, and thus, the abnormality of the circuit of the heat control system is detected with a high precision to prevent secondary disaster such as a fire surely.

Abstract: PROBLEM TO BE SOLVED: To prevent the surface of a pressure roller from damaging when an exfoliating pawl for exfoliating each sheet of paper from the pressure roller runs against the roller surface, likely when a sheet guide is moved for jam treatment. SOLUTION: A pawl displacing means for an exfoliating pawl 5 is installed so that the tip 7 of the pawl 5 separates from the position contacting with the surface of a pressure roller 2 interlocking with the operation to release a sheet guide 4 from the pressure roller 2. The pawl displacing means has a bar 12 and operating plate 13. Interlocking with release operation of the sheet guide 4, the operating plate 13 slides in the direction of arrow X1 in Fig., and thereby the bar 12 displaces the supporting shaft 8 of the pawl 5 to the left. Accordingly, the tip of the pawl 5 retracts from the guide surface 6. When the sheet guide 4 is set, the operating plate 13 slides in the direction of arrow X2, and the tip 7 of the pawl 5 makes displacement to the position contacting with the surface of the pressure roller 2.
