Patent JP-H0320125-A (JP)
Title: Power transmission device
Inventor: OBARA HIDEO
IPC: F16D35/00
Filed: 1989-06-13
Abstract: PURPOSE:To give a driver no physical disorder by providing a plurality of viscous couplings between input and output shafts, and also providing a means which changes transmission characteristic of torque with equal percentage and selectively connects such couplings. CONSTITUTION:When a selector knob 55b is moved, selective connection of a first or a second viscous coupling (hereinafter referred to as VC1, VC2) in a torque varying means 50. In the case that the selector knob 55b is on a position of P, connection is carried out at portions designated by O mark. An output member O1 is connected to an input member I2, while VC1 and VC2 are in serial viscous arrangement. As transmission coefficients of VC1 and VC2 are the same, a torque Tr is half as in the case that only VC1 is used. In the case that the knob 55b is at a position P3, both of the input members I1 and I2 are connected to each other, and the torque Tr is the same as the torque of VC1. In the case that the knob 55b is on the position of P4, the members I1 and I2, O1 and O2 are respectively connected to each other and in a parallel viscous arrangement. The torque Tr in this case is twice as that of VC1. Torque transmission characteristic is thus changed with equal percentage, thereby an operator feels no physical disorder.

Patent JP-S629208-A (JP)
Title: Measuring instrument for film thickness
Inventor: IDA YOSHIAKI
IPC: G01B11/06
Filed: 1985-07-05
Abstract: PURPOSE:To measure the thickness of an object film under non-contacting state by applying a constant AC magnetic field to the object film at right angles during the run of the object film, and converting the rotation of a plane of polarization due to the Faraday effect of the object film into light intensity and performing signal processing. CONSTITUTION:Light from a light source 3 is polarized 4 linearly and penetrates a coil 2a of a magnetic field producing device 2, passes through a magnetic tape 1, and penetrates a coil 2b of the device 2 again to enter an analyzer 5. At this time,the plane of polarization of the linear polarized light rotates owing to the Faraday effect because the film 1b of the tape 1 is made of a magnetic material. The angle of the rotation is found to obtain the film thickness. For the purpose, the light is converted 6 photoelectrically to obtain a mean value by an integrator 7 and an AC component by an AC amplifier 8, and their ratio is calculated by a divider 9. Consequently, variation of an output is compensated by variation in light power and loss variation of the light source 3 and other optical systems. Thus, the film thickness is measured under non- contacting state nor any shift in tape position.

Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent an erroneous operation caused by noises by detecting the derailment of a train when an optical fiber is cut by the falling of a detection pillar and a light passing through the optical fiber is shut off. SOLUTION: When a train derails and crashes into a detector main body 1, a detection pillar part 4 is moved to an arrow direction of receiving the crashing. When an impact force exceeds the durability of a fuse 14, the fuse 14 is cut. Then, the pillar is rotated around a pint P and falls. Following the falling of the detection pillar 11, a shaft 12 is rotated and moved while its lower end rubs an optical fiber shearing hole 9. An optical fiber 2 receives a shearing force and is cut when the shaft 12 is moved and a small hole 18 is removed from the optical fiber shearing hole 9. Thus, the optical fiber 2 is cut associatively with the falling of the detection pillar 11 and a light passed through the optical fiber 2 is shut off. Thus, an erroneous operation caused by vibration/impacts is prevented.
