Title: Optical disk driver
Inventor: USAMI MASAKI
IPC: G11B7/00
Filed: 1986-10-21
Abstract: PURPOSE:To prevent the destruction of recorded information by stopping the radiation of a laser light beam by a head until the next access request is received when it is detected that the duration time of the idle state exceeds a limit value thereby suppressing the reduction in a mean access speed. CONSTITUTION:Since an output signal 30 of an idle state detection circuit 26 goes to an L level in case of the idle state, a timer 28 is operated. If the operating time of the timer 28 exceeds a prescribed time, an output signal 31 of the timer 28 changes to an H level, resulting that an FF32 is changed to the set state and an output signal 33 goes to an H level. As a result, a control section 20 stops the operation of a laser light source 14 to stop the radiation f the laser light beam. When the access request comes, the signal 31 goes to an L level and the signal 30 goes to an H level, the FF32 is set and the signal 33 goes to an L level. The control section 20 controls a light source 14 to as to bring the intensity of the radiated laser light beam to be a prescribed intensity for information recording or reproduction.

Abstract: PURPOSE:To facilitate flow rate adjustment and output power control in such an arrangement that a shaft member is fitted in a hole in a hole member, by forming a spiral groove in either of the inner peripheral surface of the hole member and the outer peripheral surface of the shaft, and by disposing a spiral seal in the spiral groove. CONSTITUTION:A shaft member 11 in which a spiral seal 3 is fitted in a spiral groove 3 formed in the outer peripheral surface thereof, is fitted in a cylindrical hole member 4. The axial center selection of the hole member 4 has a small diameter part 4a having a diameter smaller than that of both end parts thereof, and the outer periphery of the spiral seal member 3 is made to slide on the inner peripheral surface of the small diameter part 4a. Further, it is arranged such that when fluid is allowed to flow from an inlet port 5 to an outlet port 6 which are formed in the axial both end parts of the hole member 4, the fluid is subjected to resistance in a spiral passage 7 formed by the part of the spiral seal 3, and thus obtained resistance is used to rotate the shaft member 1 by means of the spiral seal 3 so that power may be taken out. Further, in the case of the drive rotation of the shaft member 1, it functions as a pump.

Title: Strobo circuit
Inventor: HATA KOJI
IPC: G03B19/04
Filed: 1994-10-17
Abstract: PURPOSE: To make the strobo charge completion disp[lay clearly observable by using a light emitting diode. CONSTITUTION: When a strobo charging switch 7 is turned on, an oscillation transistor 13 oscillates by an oscillation transformer 14 and increases primary side current flowing in a primary coil 15 to make secondary side current flow in a secondary coil 16. The secondary side current is rectified and charged in a main capacitor 31.  Though a light emitting diode 21 does not emits light since the potential of the connecting point B is higher or slightly lower than the potential of the connecting point A at the time of the start of charging, the potential of the connecting point B gradually lowers following the increase of the charged voltage of the main capacitor 31 and when the charged voltage reaches 270V, which is the necessary minimum voltage for stroboscopic photograph, and dim light emitting occurs due to rising up voltage application at the time out of a period of back electromotive force for the oscillation transformer 14 and the bright light emitting occurs with intense output when the charged voltage becomes 290V and thus it can be known that stroboscopic lighting becomes available.

Filed: 1992-08-26
Abstract: PURPOSE:To prevent a recording layer from being degraded by the oxidation and to obtain a high quality-magneto-optical recording medium by containing a process for forming the recording layer which includes an amorphous magnetic alloy layer on the signal surface of a transparent resin substrate with a moisture concentration of <=100ppm. CONSTITUTION:In the manufacturing process of the magneto-optical recording midium, the moisture concentration in the transparent resin substrate before the formation of the recording layer, for instance the moisture concentration when the transparent resin substrate is transferred into a vacuum equipment for forming the recording layer after the injection molding of the transparent resin substrate is kept to be <=100ppm. In such case, a stabilized sensitivity is obtained as shown in fig. because the moisture concentration level is sufficiently lowered within approximately 20 minutes after the injection molding. That is, special drying equipment or the like needs not be provided as long as the transparent resin substrate is transferred into the vacuum equipment for forming the recording layer within 20 minutes after the injection molding of the transparent resin substrate.
