Title: Optical information recording medium and its production and information recording and reproducing device using the same
Inventor: KOBAYASHI SETSUO
IPC: G11B7/24
Filed: 1993-09-17
Abstract: PURPOSE:To control the relaxation process from an excitation state, to reduce the spot diameter which can be optically converged and to increase density by consisting a nonlinear transmission layer of a clathrate compd. internally contg. at least one piece of saturable absorbers. CONSTITUTION:This information recording medium is constituted by laminating the saturable absorbers 42 which are one of an absorption type of the nonlinear light transmission layer, an information recording layer 41 and a protective film layer (not shown in Fig.) on a disk substrate. The luminous fluxes from a light source are converged by a converging lens 44 from the disk substrate side through the saturable absorbers 42 to the information recording layer 41. Information bits are recorded along the center of information recording tracks on the information recording layer 41. The clathrate compd. internally contains the saturable absorbers, by which the interaction among the saturable adsorbers is decreased and the relaxation process from the excitation state is decreased. Consequently, recording and reproducing at the recording density below the photoresolving power is possible.

Title: Driving method for insulation gate type semiconductor element
Inventor: MIURA SHUNJI
IPC: H03K17/06
Filed: 1988-09-16
Abstract: PURPOSE:To drive a gate insulation type bipolar transistor(IGBT) without adding a driving circuit separately by connecting a Zener diode in series with the emitter terminal of the IGBT. CONSTITUTION:An electric charge can be accumulated via an insulation layer between a gate and a base when a voltage is applied between the gate and a collector by connecting the Zener diode 28 to the emitter terminal of the IGBT 1. Since capacitance between the gate and the collector is around five times the capacitance between the gate and the emitter in a low voltage state of the IGBT 1, a bias voltage between the gate and the emitter can automatically be increased when a forward voltage is applied by charging the capacitance between the gate and the collector in the reverse bias state between the emitter and the collector. In such a way, it is possible to drive the IGBT without adding the driving circuit additionally even when a low voltage is applied between the emitter E and the collector C.
