Filed: 1983-10-17
Abstract: PURPOSE:To eliminate delay of braking force at the compression side without encapsulating pressurized gas by making such that a second compression pressure control valve for maintaining the hydraulic pressure in a lower oil chamber at specific level will open with higher pressure than that for first compression main pressure control valve to allow only upward passing of oil. CONSTITUTION:A piston 6 is provided with an extending pressure control valve 12 for going down of oil which will determine the pressure in upper oil chamber 7 under extension stroke, first compression main pressure control valve 13 for going up of oil which will determine the pressure in lower oil chamber 8 under compression stroke and an orifice 14 communicating with both chambers 7, 8. A bottom cover 18 having a suction valve 15 communicating with an oil storage chamber 4 and second compression pressure control valve 16 to be pressurized by a valve spring 17 for maintaining the pressure in said chamber 8 higher than predetermined level while opened by pressure higher than that for said valve 13 is provided at the lower section of inner tube 3.

Title: Decurl mechanism and recording device using decurl mechanism
Inventor: SASAI KEIZO
IPC: B41J15/04
Filed: 1989-07-27
Abstract: PURPOSE:To enlarge the contact center angle of sheet material to a decurl member sufficiently by moving a guide member or the decurl member fitted on the device main body side or the cover body side forcibly at the time of opening/closing the cover body. CONSTITUTION:At the time of conveying sheet material 5, a shifting means 26 stops in the balanced state between tension applied to the sheet material 5 and energizing force by an energizing means. Accordingly, when the tension is large, the influence of the energizing force on the shifting means 26 is small, and the acting quantity of the shifting means becomes small and therefore the curvature of the sheet material 5 becomes small. On the other hand, when the tension is small, the moving quantity of the shifting means 26 becomes large, and the curvature of the sheet material 5 thereby becomes large. Curl correction corresponding to curl strength can be therefore performed. In this case, a guide member 23 or a decurl member 22 fitted on the device body side or the cover body 2 side is moved by a supporting member 24 at the time of opening/closing the cover body 2 so as to enlarge the contact center angle of the sheet material 5 to the decurl member 22.

Title: Vibration generating motor
Inventor: TSUKADA KEN
IPC: H02K7/065
Filed: 1994-07-26
Abstract: PURPOSE:To enable a vibration generating motor to generate a large vibrating force by positioning a discoid permanent magnet magnetized in the axial direction so that the magnet can move to the inside of an annular rolling wheel and a stator composed of electromagnetic coils and an iron core on the outer periphery of the rolling wheel. CONSTITUTION:A rotor 1 is composed of a discoid permanent magnet formed by cutting a cylindrical permanent magnet along two parallel planes perpendicular to the axis of the magnet. The rotor 1 is loosely positioned on the inside of a rolling wheel 2 so that the rotor 1 can freely move and rotate in the wheel 2 or roll on the inner peripheral surface of the wheel 2 while the rotor 1 is kept in contact with the wheel 2 when a force is applied to the rotor 1 from the outside. The rotor 1 is provided with iron cores 4a-4d which are separated from electromagnetic coils 3a-3d. When, for example, an electric current is made to flow to the coil 3b so that the coil 3b can generate a magnetic field in the direction in which the rotor 1 is attracted, the rotor 1 is moved to the position shown by the broken line from the vicinity of the core 4a, because the attracting force has a component in the tangential direction of the circular arc formed by the wheel 2. When the supply of the electric current to the coil 4b is stopped and another electric current is made to flow to the coil 3c, the rotor 1 moves to the position of the core 4b.

IPC: G01B21/00
Filed: 1986-08-21
Abstract: PURPOSE:To eliminate the irregularity or error of a measured value caused by the rolling direction of a lid material, by automatically finding out the grain direction of a can lid and measuring various dimensions on and after in such a state that said direction is fixed. CONSTITUTION:A can lid is held on the can lid holding stand 3 of a can lid feed truck 2 and the can lid holding stand 3 is rotated on a grain direction detecting stage A to detect the grain direction of the can lid and further rotated so as to set the grain direction to a predetermined direction to determine a can lid direction. Next, the can lid feed truck 2 successively moves between can lid dimension measuring stages B on and after in such a state that said direction is fixed and the dimension of the can lid is measured on each can lid dimension measuring stage B. As a result, since the dimension of the can lid can be measured in the same grain direction with respect to all of can lids, the irregularity of a measured value due to the difference in the grain direction can be prevented.

Abstract: PURPOSE:To detect the disconnection on secondary side by judging whether predetermined relation is present between the phase voltages of three phases on a PT secondary side, line voltage and voltage phase differences between the phases and the line voltage. CONSTITUTION:An input part 4 receives voltage from a three-phase PTC and, when the magnitude of phase voltage is larger than a value epsilon1, detection circuits 5-7 emit outputs and, when line voltage is smaller than a value K, detection circuits 8-13 perform output operation. Phase difference judge circuits 14-16 perform output operation when each phase voltage is delayed by an angle epsilon2 from line voltage and voltage judge circuits 17-19 issue outputs when the line voltage is smaller than a value K2. PT secondary circuit disconnection detection signals S1-S7 are obtained through the operation means of AND circuits 20-22, AND circuits 23-25 wherein one of input terminals is a prohibiting terminal, an AND circuit 26 and an OR circuit 27. By this constitution, the disconnection of a secondary circuit can be detected from the outputs of one set of three-phase output circuits of PT and, even when there is other line load in the secondary circuit, the disconnection of the secondary circuit can be certainly detected.

Filed: 1984-09-19
Abstract: PURPOSE:To produce a functional group-terminated polymer having a low MW dependency of the number of terminal functional groups, by polymerizing a cation-polymerizable monomer by using a specified coinitiator and a Lewis acid. CONSTITUTION:A 4-10C olefin, conjugated diene, vinyl ether or the like (e.g., isobutylene or butadiene) is used as a cation-polymerizable monomer, and a compound (coinitiator) of the formula (wherein R1, R2, R3 and R4 are each H, a lower alkyl or phenyl, R5 is -(CH2)n<->, n is 2-10, and x1 and x2 are each a halogen) and a Lewis acid (e.g., BCl3 or AlCl3) are used as a catalyst. The polymerization of the cation-polymerizable monomer by using the above catalyst system is conducted in a halohydrocarbon (e.g., methylene chloride) as a solvent, mixing the monomer with the coinitiator at the lowest possible temperature (usually, -70 deg.C) and adding a Lewis acid as an initiator to the formed system. The polymer functional group-terminated polymer obtained by the above process is useful as a raw material for polyurethanes, a material for adhesives, or the like.
