Title: Aperture control unit of camera
Inventor: KITAMURA YASUNORI
IPC: G03B7/085
Filed: 1979-06-13
Abstract: PURPOSE:To make possible the correction of stopping-down errors at the stable degree of accuracy by generating the stopping-down inhibit signal early by way of a comparator by the specified correction output before the aperture value based on photometric output reaches the set value. CONSTITUTION:A photometric circuit 2 generates the shutter second time according to the photometric output through a stop D and the output of a film sensitivity setting circuit 6 and substracts the specified correction second time output by a correcting circuit 3. This is then compared with the set shutter second time of a shutter second time setting circuit 1 in a comparator 4. The coincidence signal which is generated at the time before the correction second time when the aperture value output by the circuit 4 arrives at the corresponding set value is applied as stopping-down inhibit signal to a stopping-down inhibit circuit 5, whereby the stopping-down of the stop D is inhibited. Hence, even in such a case when photometric output-stopping- down time characteristics cannot be approximated to uniform and uniformly accelerated motions, the stopping-down errors are corrected at the stable degree of accuracy free from any mechaical delay of stopping-down and the accurate exposure controlling is accomplished.

Filed: 1982-04-30
Abstract: PURPOSE:To reduce the heat crown of rolls and to perform an excellent shape control, by shifting a work roll in its axial direction to roll a material to be rolled, in a multi-roll mill in which a pair of work rolls are respectively supported by plural intermediate rolls and back up rolls. CONSTITUTION:When the rolling of a material 1 to be rolled is started by work rolls 2 used directly after rearranging rolls, the rolls 2 are made to produce the heat crown as shown by the dotted line (a). Next, when the roll 2 is shifted by delta to the operation side, the rolling condition is shown by the figure (b), and the heat crown as shown by the dotted line is produced. Next, when the 3rd coil is rolled by shifting the roll 2 by 2delta from the condition of the figure (b), the condition is shown by the figure (c). In this case, (a), (e), and (f) show the heat crown at the time when the rolling is performed at the same position without shifting the roll 2. Then, when the rolling is performed by shifting the roll 2 together with a coil as mentioned above by comparing with these conditions, the malformation of the material 1 is restrained because the change of the quantity of the heat crown at the edge part of the sheet is small.

Title: Driving axle apparatus
Inventor: HATA HIDEYUKI
IPC: F16F1/14
Filed: 1978-06-19
Abstract: PURPOSE: To prevent the generation of noise by making a driving axle in double shaft consisting of the center shaft and the outer pipe shaft, and connecting the both end parts of the outer pipe shaft onto the center shaft so so to prevent turn, and by making the turn stop connection part at one end to idle connection, and obtaining a spring constant of the axle suitable for transmission torque.  
     CONSTITUTION: End pipes 11 and 12 are welded onto the both ends of an outer pipe shaft 3, and on the inner hole of each end pipe 11, 12, spline inner teeth lines 11a and 12a are formed which are inserted onto the splines 4 and 9 of a center shaft 2, and the teeth line 12a is broken off alternately. Thus, the outer pipe shaft 3, on the end pipe 11 side, is closely contacted with the center shaft 2, suppressing turning, and on the end pipe 12 side, is connected with the center shaft 2 with a play. In free state, a preparatory pressure torque b is applied to the end pipe 12 so that the end pipe is pressed onto the spline 9 in the direction of backward movement and turn. Thus, the spring constant of an axle 1 is made higher as the addition of constants of the shafts 2 and 3 in the vicinity of neutral, first, and second speed, and made lower as the spring constant of the shaft 2 in the vicinity of each third and fourth speed, and a variety of noise is suppressed.

Title: Production of magnetic recording medium
Inventor: SHIBAZAKI SHOJI
IPC: G11B5/845
Filed: 1989-03-27
Abstract: PURPOSE:To improve the magnetic characteristics, more particularly aspect ratio of the magnetic recording medium by impressing a magnetic field to the magnetic coating applied on a base film in the thickness direction of the coated film before the coating compd. is not dry yet, then impressing the magnetic field thereto in the longitudinal direction of the base film and drying the coating film to solidify in this state. CONSTITUTION:The film 1 coated with the magnetic coating is inserted between two magnets 2 and the magnetic field in the thickness direction of the coated film (the magnetic field in the direction perpendicular to the longitudinal direction of the film 1) is impressed to the coating in the undried state. The magnetic field in the longitudinal direction of the film 1 is thereafter impressed to the film 1 by a solenoid 3 disposed in the traveling direction of the film 1. The film 1 is put into a drying furnace 4 while the acicular particles of the magnetic coating are oriented in the longitudinal direction of the film 1. The film is thus dried in the state of impressing the magnetic field in the longitudinal direction of the film by an auxiliary solenoid 5 to maintain the acicular state oriented in the longitudinal direction of the film 1 in this state. The problem that the aspect ratio to be a measure for orientation of the acicular particles is poor is solved in this way.

Title: Laser device and operation thereof
Inventor: BAUMGART PETER MICHAEL
IPC: G02F1/11
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a laser device capable of directing diffracted beams generated from initial laser beam and having high equality toward both surfaces of a substrate simultaneously. SOLUTION: Diffracted beams are generated with energies sufficient to form texture bumps to be used on the substrate of a magnetic disk 95 by softening spots being on surfaces of the substrate. The beams are generated by a multichannel acoustic optical modulator (MCAOM) which has at least two channels (here, two channel modulator (DCAOM)). The crystal of the MCAOM has at least two mounting surfaces oriented so as to intersect an incident laser beam 16 at a common angle, that is, a Bragg angle (α). A corresponding 1-st order beam 16 is diffracted (14a, 14b) by activating arbitrary modulators 13a, 13b. The diffracted beams are preferably generated by generating two beams whose pulse intensities exceed 50% of the incident beam and which can be directed toward counter surfaces of the substrate in order to uniformize textures extremely while alternating driving signals to the modulators.

Abstract: PURPOSE:To reduce the cost for plating material, reduce the processing cost, and manufacture a reed at a low cost by Ag and Ni plating a wire work, subjecting it to the drawing process, shaping it and cutting, and then subjecting the resultant to a heat treatment. CONSTITUTION:A wire material of Ni-Fe alloy of 6mm in dia. is subjected to Ni plating process for a specified thickness, and further thereover an Ag plating is applied for a specified thickness, and thus a two-layer plated wire work is fabricated. This is subjected to a drawing process into a dia. of 0.6mm so as to yield a thin wire element. This is shaped with a press and cut to form a contact flat portion 13 and a spring flat portion 12 each having an eliptical section, and the resultant is cut into a specified length to provide a reed element, which is followed by a heat treatment for diffusion of the layers of the reed element. Thus reeds 1, 1' are accomplished. The costs become cheaper than the conventional technique with Au plating or Rh plating, and the cost for the plating material is suppressed, which associate with reduction of the processing cost, should provide cheap leads 1, 1'.
