Title: Method and apparatus for measuring coercive force of ferromagnetic substance test piece
Inventor: SUMIDA YOSHIHIRO
IPC: G01R33/12
Filed: 1983-06-27
Abstract: PURPOSE:To enable the measurement of a coercive force of a test piece simply at a high accuracy by a method wherein a test piece is magnetized in a solenoid, rotated in front of a head of a detection coil and then, a specified demagnetization is done with a demagnetizing coil. CONSTITUTION:A test piece is magnetized with a magnetizing coil 12 in a solenoid 10 and rotated in front of a head of a detection coil 28 so that the magnetic flux thereof is caused to cross the detection coil 28 at the right angle thereto to generate an induced voltage (e) by an electromagnetic induction. Then, a magnetic field necessary for cancelling the induced voltage (e) is applied anew by a demagnetizing coil 14 from outside to calculate the strength of an external magnetic field necessary for making the induced voltage (e) zero to be used as a coercive force. Thus, the coercive force of the test piece can be measured very simply at a high accuracy.

Title: Clutch cover assembly
Inventor: NAGANO TAMIO
IPC: F16D13/71
Filed: 1981-07-24
Abstract: PURPOSE:To provide a clutch cover having tabs at plural places of the inner peripheral edge to be integral therewith which can reduce bending and caulking load to the tabs and lessen deformation of the tabs by mounting slits on the tabs. CONSTITUTION:A tab 10 decreases in a sectional area for a slit 15 having a width W. Since the tab having a circular-arc section is divided by the slit 15, it is possible to reduce pressing load caused by bending and caulking in the end portions 13, which can facilitate bending and caulking work. As the caulking load decreases, a contact pressing force of wire rings 11, 12 to a diaphragm spring 4 decreases so as to lessen frictional force therebetween. Thus, the diaphragm spring 4 works smoothly so as to improve the operational sense of a clutch.

Title: Optical scanner
Inventor: KUNO TORU
IPC: B41J2/45
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To provide an optical scanner capable of stopping down a beam size in the main scanning direction remarkably smaller than a pixel size while suppressing an adverse effect due to a side lobe. SOLUTION: A light beam is divided to plural optical paths in the main scanning direction by two sheets set of triangular prisms, and the light beams divided to plural optical paths are converged on a surface to be scanned, and interference of light is caused. Thus, a Bessel beam is formed only in the main running direction. On the contrary, related to the sub-scanning direction, a Gaussian beam is formed as usual. At this time, the extremely thin beam size of 10μm extent is realized in the main scanning direction as shown in (A), while limiting the occurrence of the side lobe only in the main scanning direction.
