Filed: 1989-04-25
Abstract: PURPOSE:To enable the precise, rapid and stable manufacture of a superconductive billet and obtain a superconducting wire material having an excellent quality by combining a molding device for focusing and forming composite superconducting elements wire with heat treatment. CONSTITUTION:Composite superconducting element wires 1 are adjusted so that they can be precisely received in a vessel consisting of metal such as copper, packed in a molding device 2, and focused into a determined shape, and then low temperature annealing of 200 deg.C to 300 deg.C is applied to correct mutual bending and distortion of the composite superconducting element wires 1. Namely, before billet assembling, a guide wire or space 3 consisting of metal such as copper which is packed to fix the superconductive element wires in the gaps formed between the focused side surfaces of the superconducting element wires 1 and the vessel at the time of billet assembling can be inserted in accordance with a determined number. Hence, the composite superconductive element wires are prevented from moving in the vessel after they are packed in the vessel and a cap is installed to the vessel, and the gaps are removed to increase the filling rate, whereby a composite superconducting billet having good quality can be manufactured.

Title: Method and apparatus for detection of superposed products in flow of products divided one by one
Inventor: GEIRI SUTEIIBU RABATOSUN
IPC: G06K13/067
Filed: 1993-04-06
Abstract: PURPOSE: To more correctly sort and count the stream of products by correctly detecting the superimposing of the products in the stream of the products separated one from another. CONSTITUTION: The stream of the products separated one from another including individual products and superimposed products is made to pass through a scanning zone along a transferring route 100. The individual products and the superimposed products respectively have shadows put on the transferring route. This shadow is analyzed by measuring its width and length to decide the existence of a multilayered product at the shadow of the product. When the length of the shadow of the product exceeds the average length of the shadows with the same width as that measured before by a prescribed quantity, it is highly possible that the shadow includes more than two superimposed products. When the shadow of a product passes through the scanning zone, an attached bar code is obtained to scan each product in the shadow by means of plural bar code scanners 206, 208a and 208b.  When two different bar codes or two equal bar codes are recorded concerning the shadow of one product from the mutually exclusive scanners, it is highly possible that the shadow includes more than two superimposed products.

Title: Image forming device
Inventor: WATABE MASAO
IPC: G03G15/14
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To prevent dielectric breakdown of a photoreceptor when a high voltage is applied and to optimize the prevention of sticking of toner to a separation claw, by controlling, according to the result of the calculation of image density in the direction of the periphery of the photoreceptor, the value of a voltage applied to the separation claw. SOLUTION: 10-100 pixels of image data near a separation claw 170 in a main scanning direction are stored for each line into an FIFO memory, and the sum of movements of fixed lengths in a sub-scanning direction is calculated. The sum of the movements is converted into analog at real time by a D/A converter, and a CPU controls a DC bias value, an AC amplitude and duty in a separation claw high voltage generation circuit according to the an analog value read at an analog port. In the case the value of the addition in an adding circuit is small, it indicates toner is less in a part where the separation claw 170 abuts on a photoreceptor drum 110. Therefore, an output voltage peak value in an AC high voltage part is decreased. In the case a value added in the adding circuit is high, the output voltage peak value in the AC high voltage part is, on the contrary, increased.

Title: Differential limitting device
Inventor: MOMOJI HIROBUMI
IPC: F16H48/38
Filed: 1990-04-18
Abstract: PURPOSE:To restrict the rotation of a pinion gear by means of sliding frictional force caused by tapered roller bearing, and thereby restrict differential movement between paired drive shafts by intersecting the extension of a generating line of an outer ring raceway surface with the extension of the generating line of an inner ring raceway surface at a position isolated from the axial center of the bearing in a plane including the axial center of the tapered roller bearing. CONSTITUTION:In a plane including the bearing axial center alpha of a tapered roller bearing 9, the extension 7 of the generating line of an outer ring raceway surface 93a is intersected with the extension gamma of the generating line of an inner ring raceway surface 91a at a position A isolated from the bearing axial center alpha. By this constitu tion, a tapered roller 10a is rotated while its inclination is being restricted, the circum ferential surface of the tapered roller 10a and each raceway surface 19a and 93a are thereby mutually slid, so that frictional force is caused between them. Frictional force is also caused between the end face of the tapered roller 10a and a collar section. In this case, the aforesaid sliding frictional resistance is turned out to be the rotational resistance of the tapered roller bearing 9, so that the rotation of a pinion gear is thereby restricted. By this constitution, differential movement between paired drive shafts connected to each side gear is thereby restricted.

Abstract: PURPOSE:To obtain a noiseless still picture by obtaining the relative position relation between a rotary video head and a video track when a magnetic tape is stopped and then driving a capstan motor up to a position where a noiseless still picture should be obtained based on the data on said position relation. CONSTITUTION:A still picture reproducer detects two frequency components from four pilot signals of different frequencies recorded on a magnetic tape 1 through the 1st and 2nd filters 17 and 18. The levels of outputs of these two filters are compared with each other and at the same time the positions of magnetic heads 5-8 of a rotary drum 4 are detected and converted into electric signals. The the time point when the position signals of the head 4 change is compared with the time point when a change is produced from the comparison of the two filter output levels. Then the value which varies in response to the value of the time difference obtained from said comparison of two time points is calculated and defined as the driving time and damping time of a capstan motor 12. Then the drive of the motor 12 is controlled with the driving and damping signals.
