Title: Optical recording medium
Inventor: UKITA HIROO
IPC: G11B7/2405
Filed: 1986-01-20
Abstract: PURPOSE:To permit the detection of a track error signal or data signal with high accuracy by having a packed layer packed with a material having the refractive index approximately equal to the refractive index of a substrate in track guide grooves. CONSTITUTION:The spiral or concentrical track guide grooves 5 are formed to the substrate 4 consisting of plastic. A reflective layer 61 consisting of, for example, Al, a buffer layer 62, a recording layer 6 and the packed layer 63 are successively and respectively provided in the track guide grooves 5. The buffer layer 62 plays the role of a heat insulating material for making thermal recording by a semiconductor layer and can be formed of, for example, AlN or ZnS. The recording layer 6 can be constituted of an optical phase transformation material such as, for example, Sn Te Se, or Te-TeO2. The packed layer 63 is packed with the material having the same refractive index as the refractive index of the substrate 4 so as to be flattened by eliminating the rugged surface of the recording layer 6 and is formed of the material having the refractive index of 2-3 times the refractive index of the substrate 4. The deterioration of the track error signal or data signal quality is thus obviated.

Inventor: IZAWA MASAKI
IPC: B60G15/06
Filed: 1995-01-23
Abstract: PURPOSE: To provide an active suspension device without generating a lock phenomenon even when impulsive load is inputted from a wheel. CONSTITUTION: An electromagnetic actuator A interposed between a tube 3 connected to a body 2, and a rod 4 connected to a wheel is provided with a motor 7 enclosed in the vertically slidable state inside the tube 3 and floatingly supported by motor supporting springs 11, 12, and a ball screw 8 driven by the motor 7.
