Title: Optical recording medium
Inventor: SUZUKI HIDEFUMI
IPC: G11B7/24085
Filed: 1986-09-20
Abstract: PURPOSE:To set a tracking line without decreasing the area of a data storage area by providing a recessed part and a projecting part alternately in parallel to a data recording face of an optical recording medium and selecting a step between the recessed part and the projecting part shallower than the depth of focus of the optical system used for data write/read. CONSTITUTION:The optical recording medium is constituted by providing the recessed part 3a and the projecting part 3b alternately in parallel as a data storage area to the storage area 2 provided to the major face of a card type base 1. The recessed part 3a and the projecting part 3b are constituted by providing a step smaller than the depth of focus of the optical system in use, e.g., nearly 1mum to the upper face of the storage area 2. Since the recessed part 3a and the projecting part 3b have the step, when a light beam is radiated to the boundary E, the brightness of the reflected light of the projecting part closer to the light source is high and that of the recessed part is low. In this case, since the step is selected to be smaller than the depth of focus of the optical system used for read/write, the brightness distribution of the reflected light is unchanged even if focusing is applied to the light beam for read/write.

IPC: H05K3/46
Filed: 1993-09-08
Abstract: PURPOSE:To prevent the separation of via sections from an insulating resin layer and the degradation in insulating performance of the insulating resin, by forming a close contact barrier layer on the underside of the via sections in contact with the insulating resin layer to improve the adhesion between the via sections and the insulating resin layer and prevent the diffusion of metal composing the via sections into the insulating resin layer. CONSTITUTION:A close contact barrier layer 22 is formed on the underside of via sections 20 in contact with an insulating resin layer 12. The close contact barrier layer 22 is for improving the adhesion between the insulating resin layer 12 and a metal layer 24 and for preventing metal forming the metal layer 24 from diffusing into the insulating resin layer 12. The close contact barrier layer 22 eliminates the degradation in insulating performance of the insulating resin 12 at the via sections 20. In addition the through holes for the via sections are tapered, and their diameter is smaller with the proximity to the bottom where the land sections 28 of a conductive pattern 17 formed on the underside of the insulating resin layer 12. Therefore, the close contact barrier layer 22, uniform in thickness, can be easily formed by sputtering, for example. When the tapered through holes are filled with metal by plating to form the via sections 22, the conductive pattern is formed simultaneously.

Filed: 1983-11-28
Abstract: PURPOSE:To permit control of brake with the optimum slip rate without measuring a car speed, by reducing the brake torque for wheels when each of a wheel- speed signal and a wheel acceleration signal is smaller than each standard value. CONSTITUTION:An estimation apparatus 32 estimates a car-speed signal U by selecting the max. out of each wheel speed and reducing the wheel speed at a constant rate, and a setting circuit 33 divides the car-speed signal U in a prescribed ratio and outputs a standard wheel-speed signal UR. The wheel speed signal UWI detected by detection circuits 34 and 35 is compared with the standard signal in a comparator 36. The wheel acceleration signal U'WI detected by a differential circuit 37 is compared with a standard wheel deceleration signal -V'WO in a comparator 40. Since the inlet valve 20 of a decompressor operates only when the outputs of the both comparators 36 and 40 exist, the control torque can be controlled correctly so that the optimum slip rate can be obtained.
