Title: Stamper for molding optical disk substrate, production of the stamper, production of optical disk substrate, production of optical disk, optical disk substrate, and optical disk
Inventor: MURATA SHIYOUZOU
IPC: B29C33/40
Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To improve transfer properties and tact-up of an optical disk substrate molding cycle. SOLUTION: An insulating layer 7 is formed in a stamper 1 for molding an optical disk substrate. The layer 7 is formed along the transfer surface 11 for molding the optical disk substrate in a part other than the transfer surface 11. When a molten resin is injected into the cavity of a mold with the use of the layer 7, by the insulating function of the layer 7, after the packing of the molten resin, even when a mold of a lower temperature than that of a conventional mold is used, by the increase of the temperature of the resin contacting the stamper, enough transfer properties can be obtained. Accordingly, the good transfer properties can be maintained by a higher transfer temperature, and the tact-up of an optical disk substrate molding cycle can be attempted by a lower mold temperature.

Abstract: PURPOSE:To obtain tracking signals having a uniform grade and uniform quality by providing information recording regions and track regions which are different in optical characteristics from said regions and have no ruggedness for guiding laser beams for recording and reproducing to optical recording layers. CONSTITUTION:Transparent substrates 1a, 1b laminated with the optical recording layers 4a, 4b are stuck to each other by an adhesive agent (or adhesive layer in common use as a spacer) via spacers 2 so as to sandwich an air layer 3. The optical recording layers 4a, 4b are divided to exposing parts 5 and nonexposing parts 6 which are different in optical characteristics, mainly in reflectivity. The exposing parts 5 serve as the track regions and the nonexposing parts 6 as the information writing regions. The tracking signals are, therefore, obtd. even if the phase difference in reflected light is not utilized. Exfoliation from a stamper is obviated and the change in the surface shape of the recording layers 4a, 4b is obviated as well. The degradation in the accuracy of the substrate surfaces and recording layer surfaces is thereby obviated and the noise level is kept low.

Filed: 1988-11-29
Abstract: PURPOSE:To make the constitution of a torque sensor compact and to mount the detector on a differential device having a small space by detecting torque from the pressure applied on a piezoelectric element provided between the fitting section of a drive-side member and fitting section of a load-side member. CONSTITUTION:A fitting hole (fitting section) 6 into which the front end 7a (fitting section) of a pinion shaft (load-side member) 7 is inserted is formed in a differential case 2b. When torque is transmitted from a drive-side member 2 to the load-side member 7, the torque is transmitted through the fitting section of the members 2 and 7, since the fitting section 7a of the member 7 is inserted into the fitting 6 section of the member 2. When the torque is transmitted, a piezoelectric element 8 put between the fitting sections 6 and 7a is pressed and the torque is detected from the pressing force, since the pressing force is proportional to the torque. Since the torque detection is performed without using any torsion bar, but using the piezo-electric element 8, this torque detector can be mounted on, for example, a differential device having no spare space.
