Title: Recording medium reproducer and recording medium reproducing method
Inventor: NAKANO SATOSHI
IPC: G11B7/20
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To read out data of a DVD(a digital video disk) and a CD(a compact disk) 'whose thicknesses of substrates arc different by one optical pickup device. SOLUTION: A laser doide 41 irradiates a CD 10 or a DVD with a laser beam via a beam splitter 42. an objective lens 43. Then, the laser beam reflected by the CD 10 or the DVD is made incident on a photodoide 44 via the objective lens 43, the beam splitter 42 and an aperture 61. The numerical aperture of the objective lens 43 is made large to be 0.6 in oreder to read out data from the DVD on which data are stored in a density higher than that of the CD 10 and in the case of reading the CD 10, a device is apt to be affected by aberration. Consequently, the aperture 61 makes only a return light whose NA is within about 0.3 pass so as not to be affected by aberration to make the photodoide 44 not detect the return light having an NA larger than 0.3.

Title: Physical quantity display device
Inventor: OKADA HIDEHIKO
IPC: G01D5/244
Filed: 1978-05-15
Abstract: PURPOSE: To enable stable displaying to be accomplished by so constituting a time constant circuit and a time constant correcting circuit that the output signal becomes only in one direction of increase or decrease despite the existence of an increase or decrease in the original level signal.  
     CONSTITUTION: When the level difference of the level signal S 1  and the output signal S 2  of a time constant circuit 2 is within the specified width, the time constant of the time constant circuit 2 is made the first time constant and when it is other than the specified width, the time constant of the time constant circuit 2 is made the second time constant and the output signal S 2  of this time constant circuit 2 is let to follow up the level signal S 1 . Said output signal is then displayed. This enables the device to be so constituted that the output signal S 2  following up the level signal S 1  and having less undulations than the level signal S 1  is obtained by the first time constant. In addition, the time constant correcting circuit 3 causes the output signal S 2  of the time constant circuit 2 to follow up to the level signal S 1  fast at the operation starting of the time constant circuit 2 or at the abrupt changing of the level signal S 1 , hence stable displaying may be accomplished.

Title: Large current winding
Inventor: IKEDA SHINYA
IPC: H01F41/10
Filed: 1979-05-10
Abstract: PURPOSE:To reduce the loss of a large current winding due to its reactance and simplify the bushing therefor by leading out lead wires from the upper or lower ends of a large current planar conductive coil while superimposing the coils in the same angle on the circumference of the coil when leading out the lead wires. CONSTITUTION:When forming the winding of an electromagnetic induction apparatus for supplying a large current to a load such as a transformer for a furnace or a rectifier or the like with a normal planar conductor, the lead wires are led out from the upper of lower ends of the winding while superimposing the conductors in the same angle of the circumference of the conductor. That is, the planar conductor 8 is wound on the winding, and the lead wires a are gathered at one upper or lower ends of the conductors 8 and thus superimposed to be led out. In this manner, the reactance and leakage magnetic flux of the lead wires may be reduced to decrease the heat loss applied to a structure and to further simplify the bushing structure provided on a cover.
