Title: Method for continuously casting metal strip
Inventor: KASAMA AKIO
IPC: B22D11/06
Filed: 1987-03-30
Abstract: PURPOSE:To operate the process from casting start to steady state under stable condition and to improve the yield of a metal strip by adopting a program control method at the time of producing the metal strip directly from molten metal by twin roll type continuous casting apparatus. CONSTITUTION:Two cooling rolls 1a, 1b are rotated mutually toward reverse direction and solidified shells 3 in the molten metal are formed on the surfaces of both rolls from molten metal pool 2 formed in gap between both rolls and pressure-welded and integrated by the roll gap 4, to continuously draw as the metal strip 5. In this case, by program-controlling pouring rate of the molten metal into the molten metal pool 2 and drawing speed of the metal strip 5 under consideration of capacity of the casting apparatus, the pouring rate and the drawing speed corresponding to the aimed strip thickness are held and the casting start can be executed under stable condition. The time from the casting start to the steady state is shortened and the operation is stabilized at early time and waste part to be cut at tip part of the metal strip is reduced and the yield of product is improved.

Title: Optical fiber laser gyroscope
Inventor: KAJIOKA HIROSHI
IPC: G01C19/72
Filed: 1982-05-11
Abstract: PURPOSE:To make it possible to detect rotating directions, by making output light circular polarization once by a 1/4 wavelength plate, thereby changing the output of a differential amplifier into a positive or negative value depending on the rotating directions. CONSTITUTION:A half of laser light from a light source 1 passes a BS (beam splitter) 3. The S polarization component and P polarization component of the linearly polarized light in the bearing of 45 degrees are reflected by and transmitted through a PBS (polarized light beam splitter) 5. When a plane of polarization preserved optical fiber coil 9 is not rotated, the phase difference between the transmitted light in the counterclockwise direction and the transmitted light in the clockwise direction is equal, and the light taken out of the BS3 is linearly polarized. When a 1/4 wavel length plate 10 is placed at the bearing of 45 degrees, the output light becomes the circularly polarized light. In a PBS11, the polarized component is taken out, the output of a photoelectric transducer 12 is guided to a differential amplifier 13, and the output is observed. When the plane of the polarization preserved optical fiber coil 9 is not rotated, the output is zero. When the coil is rotated right and left, the output having the positive or negative polarity appears. By integrating the differential amplifier 13, the direction from the initial state can be found.

Abstract: PURPOSE: To perform correction at the time of sticking with allowance by covering an outer periphery of a cylindrical duct body with an air conditioning sheet paper through a delayed type adhesive, then heating the delayed type adhesive to cause thermal activation of its adhesive constituent and sticking the air conditioning sheet paper to the duct body. CONSTITUTION: A delayed type adhesive is applied on at least one of an air conditioning duct body 1 of metallic sheet formed to have a cylindrical shape having a square or circular or elliptical cross section and an air conditioning sheet paper. After the application, the adhesive is dried to permit the air conditioning duct body 1 to be covered with the air conditioning sheet, and is heated to cause an adhesive constituent of the delayed type adhesive to be subjected to thermal activation, so that the air conditioning duct body 1 and the air conditioning sheet are made to be stuck together.

Abstract: PURPOSE:To prevent a recording paper or the like from being contaminated with splashes or the like, by a method wherein a guide member for flushing a concentrated magnetic ink generated at non-recording time by a non-concentrated magnetic ink is provided with a magnet and an ink-recovering circuit having an ink-receiving part. CONSTITUTION:When recording is resumed after resting for a predetermined period of time, an opening part 45 is closed by a closing lid 44, and the guide member 35 is rotated to form a passage extending from a slit part 14 to the ink-recovering passage 55. Then, a non-concentrated magnetic ink is forcedly blown out through a slit part 14 of the opening part to wash a slanted surface 17 of an ink-raising magnet 12, a stylus part 11 and an end face 18 of an auxiliary magnet, whereby the dried or concentrated magnetic ink is washed away, and is recovered through the passage 55. The magnetic ink thus blown out is decelerated by receiving an attractive force of a magnet 54 provided on an inside surface 47 of a guide lid. Therefore, little ink mist and little splashes are generated, and even when they are generated, they are not diffused, and further, splashing is prevented also by the ink-receiving part 49. Accordingly, the recording paper and the interior of the device can be prevented from being contaminated.

Filed: 1981-05-25
Abstract: PURPOSE:To prevent the L camber of a strip and to improve workability by spraying fluid to the part ahead of the side where the L camber of the strip produced by asymmetrical rolling initiates. CONSTITUTION:When a strip 3 is rolled between a work roll 1 of a small diameter and a work roll 2 of a diameter larger than this, it comes out from the rolls 1, 2 while producing an L camber on the roll 1 side. Thereupon, fluid jets 8 are sprayed onto the surface of the side where the L camber at the leading end of the strip 3 initiates on the outlet side of the rolls 1, 2, whereby pressure is excerted to the strip. In this way, leveling force acts and the camber of the strip 3 is prevented.
