Abstract: PURPOSE:To greatly enhance a recording sensitivity and to satisfactorily execute recording and reproducing of information by selecting the film thicknesses of a transparent layer and recording layer in such a manner that the reflectivity of the incident light from the rear surface side of the substrate is confined to a prescribed value or below. CONSTITUTION:The substrate 11 has a flat disk shape made of glass, etc., and the recording layer 13 is provided via the transparent film 12 having the refractive index larger than the refractive index of the substrate 11 is provided on the surface of the substrate 11.

Title: Infeed device for honing machine
Inventor: NAGAI TAKUJI
IPC: B24B33/06
Filed: 1986-05-28
Abstract: PURPOSE:To improve the extent of machining efficiency as well as to prevent any machining failure from occurring, by measuring dimensions of a workpiece during operation, detecting a removal rate and, when this rate is lowered to less than a lower limit speed, after once having the diameter of a grindstone contracted, and again expanding it. CONSTITUTION:At the time of grinding a workpiece W in a way of reciprocating a grindstone 6 as rotating it, radial dimensions of an inner circumferential surface of the workpiece W are measured by an air micro-measuring instrument 19 from a pressure variation of pressurized air to a nozzle 16a. And, on the basis of this, a measuring infeed rate V at every moment is detected by an infeed rate computing element 23. Likwise, a lower limit speed signal V0 is set by a lower limit speed setter 24. And, an infeed controller compares the measuring infeed rate V with the lower limit speed V0, and when the rate V comes down to less than the V0, the grindstone is once contacted in diameter and then again it is expanded. Therefore, metallic powder so far loaded on the grindstone due to vibration at the time of diametral expansion is removed, thus it becomes self-formed and sharpened. With this constitution, any drop in a removal rate is kept back and, what is more, any machining failure is prevented from occurring.

Abstract: PURPOSE:To enable a film having a uniform thickness to be applied on a substrate even if it has steps on the surface, by angularly rotating the substrate on an axis deviated from the center of the substrate while rotating it around its own center. CONSTITUTION:A semiconductor substrate 4 is arranged on each chuck 2 and the substrate 4 is suction held on the chuck 2 by evacuation through a vacuum piping 8. A solution is dropped onto each substrate 4 from each nozzle 13. The substrate 4 held on the chuck 2 is rotated around its own center 4a, while it is angularly rotated on the center of rotation 1 provided by a shaft 7a deviated from the center 4a. Accordingly, the substrate 4 is subjected not only to centrifugal force acting thereon in the radial directions but also subjected to centrifugal force generated by its rotation on the axis deviated from the center 4a. The solution is thereby diffused to all the directions over the substrate 4 to form a thin film thereon. In this manner, the film having a uniform thickness can be formed on the substrate even if the substrate has steps on the surface.

Abstract: PURPOSE:To obtain the APD of excellent characteristic by good guard ring effect by enabling a semiconductor layer in which the light receiving region is embedded to be epitaxially grown without defects by forming a mask out of Si nitride. CONSTITUTION:Semiconductor layers 2-4 are successively epitaxially grown on an N type InP substrate 1. An Si nitride film is formed on the InP layer 4, and a circuar mask 5 is formed by patterning this film. Next, this layer is formed into a mesa by removing the periphery of the light receiving region. Then, an N type InP layr 6 is epitaxially grown in liquid phase as the buried layer. An acceptor impurity is diffused by providing a mask 7 after removal of the mask 5. This diffusion enables a P type region to be formed over the InP layer 4 of the light receiving region and the InP layer 6 of the buried layer. Since the layer 6 has an n type impurity concentration of approx. 1X10<15>cm<-3>, even the region in the skirt of the impurity diffusion turns into a P type region 9, resulting in the construction of a guard ring.
