Title: Magneto-optical recording medium
Inventor: KANEKO YUJIRO
IPC: G11B11/10
Filed: 1993-03-08
Abstract: PURPOSE:To suppress the increase of coercive force due to both-side coating in a magneto-optical recording medium having a structure obtd. by coating both sides of a recording layer with protective layers and to attain a high C/N in a low magnetic field. CONSTITUTION:A protective layer 2, a recording layer 3, a protective layer 4 and a reflecting layer 5 are successively laminated on a transparent substrate 1. The protective layers 2, 4 are formed under a reduced pressure of <=5m Torr.

Title: Dielectric isolation semiconductor device and its manufacture
Inventor: ENDO KOICHI
IPC: H01L29/861
Filed: 1995-03-30
Abstract: PURPOSE: To obtain a diode, an IGBT or the like which can realize a high-speed switching operation and whose structure is new without using a carrier life control technique by specifying the width of a part sandwiched between element isolation insulating films in a current route formed between a first main electrode and a second main electrode. CONSTITUTION: The mutual distance W between one pair of trench sidewall insulating films 1 along a current route is set at 5μm or lower. Since it is difficult to work the thickness (t) of a substrate to be thin considering a breakdown strength, an element whose width W is made thin in the transverse direction is formed. That is to say, the mutual distance W between the pair of trench sidewall insulating films 1 along the current route is made small with reference to the thickness (t) of an active layer and the distance (l) between both electrodes. As a result, the effective area of a semiconductor element such as a diode or the like can be suppressed small, and the reverse recovery charge of the diode can be reduced. Consequently, a semiconductor device such as a high-speed diode, a high-speed IGBT or the like can be realized without controlling a lifetime.

Title: Magneto-optical disk
Inventor: YAMAZAKI YUJI
IPC: G11B11/10
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To enable the rotation even in a high-speed rotating region by forming a magneto-optical disk which is mounted on a spindle and executes recording and reproducing in such a manner that the contacting area of a hub with a substrate and the projection area of the substrate of the magneto-optical disk satisfy a specific relation. SOLUTION: A hub 3 for magnetic clamping is mounted at the substrate in the state liberated from the substrate 1. The hub 3 is attracted by a magnet 4 mounted at the spindle 2. In such a case, the hub consists of a material having coefficient of thermal conductivity of >=0.05 (cal/ deg.C.cm.s). The projection area of the substrate, defined as X, and a contacting area of the hub 3 for magnetic clamping with the substrate, defined as Y, are specified to Y/X>=0.02, by which the friction force between the substrate and the hub is assured. The slip generated between the substrate and the hub by rotation may thus be prevented and rotation unevenness may be suppressed.  Further, the holding power of the substrate increases in spite of the wobbling of surface induced by the rotation unevenness and the turbulence generated in a cartridge by rotation and, therefore, the effect of lessening the influence may be obtained.

Abstract: PURPOSE:To enhance the output and as well fuel consumption performances of an engine, by providing such an arrangement that a crank angle at which the internal pressure of a cylinder is maximum is obtained, an actual ignition timing is obtained by searching a map which is beforehand stored in a memory means, in accordance with the thus obtained crank angle, and the ignition timing is controlled in dependence upon whether the firing is made at a first ignition or not. CONSTITUTION:An angle detecting means 3 detects a crank angle at which the internal pressure of a cylinder is maximum, in accordance with the outputs of a crank angle sensor 1 and a cylinder pressure sensor 2. Further, in accordance with the output of the angle detecting means 3 and as well the output of a memory means 4 that stores therein the relation between the crank angle at which the internal pressure of the cylinder is maximum and the firing timing, an actual firing timing is determined by a firing judging means 5. When the firing is normally made at a first ignition, an ignition timing estimating means 6 estimates the ignition timing to set the ignition timing at a predetermined position. On the contrary, when the firing is missed at the first ignition, the ignition timing estimating means 6 estimates the ignition timing to retard the latter. Then, in accordance with the estimated ignition timing, an ignition device 8 is controlled by means of an ignition timing control means 7.
