Title: Screw fastening device
Inventor: HISAKADO TAKAO
IPC: B25B23/02
Filed: 1985-12-18
Abstract: PURPOSE:To aim at enhancing the ability of working, by providing a first set of a bit and a holder and a second set of a bit and a holder, and the like so that torque may be normally transmitted even though both first and second bits are inclined thereby it is possible to prevent damages of screws and workpieces. CONSTITUTION:When a motor 11 rotates to rotate a connecting rod 7a and a second holder 5, a second bit 4 rotates a first bit 5 through a groove in a first folder 2. When a screw on a workpiece with which the first bit 1 is inclined is to be rotated, the first bid 1 and the first holder 2 are inclined, and therefore, the workpiece may be rotated with not external force other than a thrust force being exerted to the screw 12. Further, a gap is formed between the second holder 5a and the connecting rod 7a in order to prevent any eccentric force other than torque from being effected. With this arrangement it is possible to enhance the ability of working.

Title: Sample-and-hold circuit
Inventor: MUSHA HIROBUMI
IPC: G11C27/02
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To obtain a fast sample-and-hold circuit of a small droop rate and a short acquisition period by sampling and holding the output voltage of a difference between the output voltage and the input voltage of a D/A converter. SOLUTION: A D/A converter 34 generating a voltage V2 following up an input voltage V1 is provided to subtract by this voltage V2 to convert to a fine voltage V3. The fine voltage V3 is sample-and-hold by a sample-and-hold means 22 and the held voltage V4 and the voltage V2 of the converter 34 are added by the adder 42 to output a voltage V5. Consequently, as the voltage V3 to sample-and-hold is made a finer than the input voltage V1 in this means 22, a reduced voltage due to a droop rate at the means 22 is made relatively low and the means 22 of a low droop rate is obtained as the result.

Title: Optical fiber type liquid detector
Inventor: SHIMOYAMA HIRONORI
IPC: G02B6/24
Filed: 1990-10-24
Abstract: PURPOSE:To make the structure of a detector simple and inexpensive and to enable quick and reliable detection of permeation of a liquid by a construction wherein at least a melt-stretched part of an optical fiber melt coupler is held in a protective container having a liquid inflow port. CONSTITUTION:At least a melt-stretched part 2 of an optical fiber melt coupler 1 is held in a protective container 3 having a liquid inflow port 4 through which a liquid flows in from outside. When no liquid permeates into a closure D, the periphery of the stretched part 2 is covered with air of a refractive index n3 = 1, and therefore a light propagated through the stretched part 2 is propagated in the same way as in a conventional optical fiber melt coupler 1. When the liquid permeates into the closure D, water flows in from the liquid inflow port 4 formed in the protective container 3 of the coupler 1 and it comes into contact with the stretched part 2 and immerses it. Since the refractive index of the water is n3 = 1.3, on the occasion, the way of propagation of the light through the stretched part 2 changes and a transmission loss of the light increases. Since the increase of the transmission loss occurs immediately when the stretched part 2 is brought into contact with the water, the permeation of the water can be discriminated quickly and accurately.
