Inventor: TAKEMURA KOUICHI
IPC: C21D11/00
Filed: 1980-05-16
Abstract: PURPOSE:To maintain tension in each position constant and stabilize tension distributions by disposing tension detectors to front and rear bridle rollers as well as their intermediate, and operating motor voltage by reference tension values and tension signals. CONSTITUTION:In a carrying plant for strip 5, load cells 45, 44, 42 are disposed just behind front bridle rolls 7, just before rear bridle rolls 8 and at their intermediate, respectively.

Title: Heat removing apparatus for high heat load
Inventor: KAHATA YASUO
IPC: F22B37/18
Filed: 1994-04-01
Abstract: PURPOSE:To improve performance of heat transfer without varying locally the flow passage resistance of cooling tubes by making the flow passage resistance of the whole tube of the cooling tubes at portions having a high heat flux smaller than that of the cooling tubes at portions having a low heat flux. CONSTITUTION:Respective ends of multiple cooling tubes 3, each being formed in a right circular tubular state as a heat removing tube, are adjacent to one another and connectively communicate in the form of a plurality of steps with a refrigerant inlet pipe 1 and a refrigerant outlet pipe 2, both being arranged in parallel with each other at a fixed interval, respectively. A spiral tape 4 is provided in each cooling tube 3 along the axial direction of each cooling tube 3a. The spiral tape 4 is formed so as to have a larger torsional ratio in a region (b) where the intensity of a neutral particle beam to be directed is high. Accordingly, the torsional, ratio of the spiral tape in the cooling tubes which receive a high heat flux becomes larger as compared with that in other positions of the cooling tubes, whereby the flow passage resistance of the cooling tubes is small and more cooling water flows. In this case, the torsional ratio means a ratio of a torsional pitch at an angle of 180 deg. to the inner diameter of the tube.

Title: Magnetic recording and reproducing device
Inventor: NAKAYAMA MAKOTO
IPC: G11B5/596
Filed: 1990-03-15
Abstract: PURPOSE:To accomplish consecutive servo actions and to improve tracking accuracy by previously writing a servo signal in the deep layer part of a medium and always reading out the servo signal by a preceding erasing head. CONSTITUTION:Ordinary data is recorded in the surface part 7 of a magnetic layer, and the servo signal is recorded in the deep layer part 8 which is just under a recording track 7 all over the periphery of a floppy disk 6 being the medium. At the time of recording the data, the direct current erasion of the medium is performed at the preceding erasing gap 2 and the data is recorded at a write and readout gap 3. The depth of the erasion and recording in such a case is set so as not to influence the deep layer part 8. Then, an amplifier 11 is made in an acting state regardless of recording or reproducing the data. Therefore, even when a DC current is applied to an erasing coil 4 at the time of recording the data, servo information is obtained in a stat where a DC bias voltage is impressed on the servo signal in the deep layer part 8. Thus, the consecutive servo actions are accomplished and the tracking accuracy is improved.

Now, in the event a part of brown color different from the right color, for example, white color is sent in, the brown color is detected by means of a color difference detection element 46. An air cylinder 40 of a parts exclusion device 14 is operated in response to this detected signal, and a rod 42 is projected to drop this part into the bowl 1, while a part of the right white color keeps on to be sent to the next process from a shoot.

Title: Positioning method for prism for forming laser beam
Inventor: OGURA YUKIO
IPC: G02B7/18
Filed: 1981-04-28
Abstract: PURPOSE:To make positioning of a prism simply and in a short time by keeping the relative position of the prism and a semiconductor laser so as to occupy the center of a laser projected from a prism nearly a fixed position at all times. CONSTITUTION:The angle of incidence i1, and angle of rotation i2 of a prism 3 are linked by an interlocking device and so changed that the center Ld of a beam from a semiconductor laser, not shown in the figure, always passes the point of emergence 0 of the prism 3 and proceeds in the direction of optical axis X when the prism 3 is rotated. Thus, by changing i1 and i2, the ratio of diameters of incident beams D1 to D2 also changes and elliptically distributed beam can be formed as desired.

Abstract: PURPOSE:To form a film having different lustrous color tones and excellent resistance to wear and corrosion in the stage of subjecting the surface of base materials for external parts for a timepiece, etc. to ion plating with Ti as an evaporating source by using nitrogen or specific hydrocarbon for a reactive gas. CONSTITUTION:Plural base bodies 6 consisting of external parts such as cases, bands, etc. for a timepiece are attached to a base body holder 2 in a vacuum chamber 1 and a Ti evaporating source 3 is disposed below said holder. The inside of the chamber 1 is evacuated to a vacuum and thereafter gaseous Ar is introduced under a low pressure into the chamber through an inlet 8. A positive voltage is impressed to an anode 10 by an anode power source 9 to execute a bombarding treatment. Gaseous N2 or gaseous chain hydrocarbon such as ethylene, methane or the like is then introduced into the chamber and the source 3 is heated to generate Ti vapor which is ionized by the anode 10. A switch 5 for a cathode power source 4 is turned on to impress a negative voltage to the bodies 6 so that the hard layer of a different color tone consisting of yellow TiN or black TiC are formed.

Title: Echo eliminator
Inventor: MAKINO SHOJI
IPC: H04B3/23
Filed: 1987-03-23
Abstract: PURPOSE:To estimate the gradient of an average square error curved surface with high accuracy, to eliminate noise from an adaptive process, and to improve call quality, by controlling the propagation characteristic of a pseudo echo path repeatedly so as to set n-sample values outputted from a subtractor at minimum. CONSTITUTION:The titled device is the one by which the propagation characteristic of the pseudo echo path 8a is controlled repeatedly at every phase so as to set the n-sample values outputted from the subtractors 10-1-10-n at minimum by using a bit of average correction information generated by averaging n- correction information generated from the n-sample values of delivery signals outputted from second thin-out circuits 15-1-15-n and the n-sample values outputted from the subtractors 10-1-10-n. By using the bit of average correction information from which a wasteful noise component generated by averaging the n-correction information being generated at every phase is eliminated, the propagation characteristic of the pseudo echo path 8a is controlled repeatedly, and echo is converged. In such a way, an echo elimination quantity can be increased.

Abstract: PURPOSE:To permit maintenance of stripping performance for a long period of time without flawing the surface of a photosensitive body by constituting a paper stripping pawl of a pawl member the front end part of which has a hollow curved shape and a stripping pawl body which supports said pawl member and guides stripped paper. CONSTITUTION:The pawl member 1 which is produced by a photoetching method of a stainless steel sheet and has an approximately triangular shape in the plane shape on the front end side is supported to a grasping part 5 of the stripping pawl body 2. The base 3 side in the front end part of the pawl member is formed to the hollow curved shape having the thicknesses increasing gradually from the front end side toward the root end side and, therefore, the paper P is guided in approximately the same direction as the conveying direction of the photosensitive drum 7 right after the collision and is then guided gradually toward the lower side when the front end of the paper P conveyed by the movement of the drum 7 collides against the front end of the pawl member 1. Since the component of force F2 of the impact force F1 decreases, the drum 7 is hardly flawed.
