Title: Guidance for wire
Inventor: UCHIDA HIROYUKI
IPC: B21B39/14
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To prolong the life of a guide for wires by simple constitution of equipment by fixing a pipe for guiding running wires by holding the pipe between rectangular parallelepiped members having a V-shaped groove from upper and lower sides. SOLUTION: The rectangular parallelepiped member 12 having the V-shaped groove 18 is installed in a fixing frame 14, the pipe 11 is installed on the member, the rectangular parallelepiped member 13 having the downward V-shaped groove 19 is placed so that the pipe 11 is put between the members and they are fixed to the fixing frame 14 with a cotter 15. When the inside of the pipe 11 is unevenly worn, by removing the cotter 15, lifting the upper rectangular parallelepiped member 13, revolving the pipe 11 by 90 deg. or 180 deg. on the coaxial center corresponding to a wear state and again fixing the upper rectangular parallelepiped member 13, the life of the pipe is prolonged.  Because the lower rectangular parallelepiped member 12 is left fixed, when the pipe 11 is placed on its V-shaped groove 18, the center is adjusted at that point of time, the adjustment of the pass line is unnecessary after resetting. Only the pipe 11 is changed, so the changing work is easily executed in a short time. Stainless steel is desirable as the material of the pipe.

Title: Method for supplying mercury to bulb
Inventor: NARUO HIDEAKI
IPC: H01J9/395
Filed: 1982-06-30
Abstract: PURPOSE:To supply a correctly-measured, very small amount of mercury to a bulb and also to readily change the amount of the mercury to be supplied, by pushing up mercury through a small hole to allow the same to take a spherical shape, applying a light beam to the sphere of mercury for measurement and preparation of the required amount of mercury, and supplying the mercury thus prepared to the bulb. CONSTITUTION:Mercury filled in the mercury reservoir 1 is pushed by upward movement of the push-up piston 3 through the small-bore tube 4 and the small hole 5 into the measurement chamber 6. A light beam from the projector 8 is applied to the mercury 7 which was pushed through the samll hole 5 into the measurement chamber and took a spherical shape by its surface tension, whereby a projected image of the mercury 7 is focused on the light receiver 9. The photoelectric current developed on the photosensitive surface of the light receiver 9 is converted into a voltage to be measured by a voltmeter V. If a predetermined amount of mercury is obtained in the measurement chamber through automatic up-and-down movement of the press-up piston 3, then a gas is blown from the blow tube 10 to send the predetermined amount of mercury to the distribution tube 11 communicating with the exhaust tube of the fluorescent lamp, and the mercury can thus be supplied to the glass bulb of the fluorescent lamp.

Filed: 1979-08-31
Abstract: PURPOSE: To prevent the malfunction of the field-type sensor caused by a swinging body or noises by arranging a plurality of sensing wires on both sides of an exciting wire to sense the difference between the voltage outputs of the sensing wires and the moving direction of an object being sensed.  
     CONSTITUTION: The exciting wire 2 supplied with an oscillation output from an oscillator 1 is provided, and at least two sensing wires 3a and 3b are arranged on both sides of the wire 2. Voltages VA and VB of the sensing wires 3a and 3b and a voltage VA-VB vary their levels respectively. When the object M moves in the direction of from (a) to (e), VB and VA-VB are changed from opposite phase to in-phase. On the other hand, when the object M moves in the opposite direction, VB and VA-VB are changed from in-phase to opposite phase. Each of the reversing signals having such phase relation is converted into a rectangular wave to actuate the relay of a switching circuit 7 through a phase changing amount detecting circuit 6. By the constitution, when the object M passes across the sensing wires 3a and 3b, its passing direction is sensed. Consequently, the malfunction caused by a swinging body or noises can be prevented.

Title: Concrete clad material for interior/exterior use and production thereof
Inventor: AKIHAMA SHIGEYUKI
IPC: B28B1/50
Filed: 1987-05-08
Abstract: PURPOSE:To effectively utilize an ALC product as the interior/exterior use material of a building while sufficiently developing the characteristics thereof, by adhering a thin layer of carbon fiber reinforced concrete to the surface of aerated concrete. CONSTITUTION:Carbon fiber reinforced concrete is molded to form a CFRC thin plate 5 and ALC is cast on the back surface of the CFRC before the curing of CFRC is not completed. The uncured CFRC and the uncured ALC come to be brought into contact with each other and the bonding surfaces of both of them become tight and the mutual diffusion of a binder is also generated at the interface thereof. Since the clad mold product 7 consisting of the uncured CFRC and the uncured ALC is aged in an autoclave, sufficient strength is imparted to the ALC and, at the same time, the adhesive strength at the bonding surfaces of both material is made sufficient and the shrinkage of the CFRC with the elapse of time is prevented. The autoclave ageing is performed at about 180 deg.C under steam pressure.
