The pressure in the reaction system is maintained under 5Torr. The non-electrode electric discharge is generated by a microwave oscillator 18 to form the c-BN film on the surface of the substrate 20 heated to 300 to 1300 deg.C. The mol.wt., i.e., the diffusion rate of the gaseous mixture and the absorption efficiency of the microwaves are controlled by adequately selecting the flow rate ratios off >=2 kinds of the inert gases. The nonuniformity and instability of the plasma are suppressed in this way and the film having the desired film quality and thickness is formed with the good reproducibility.

Abstract: PURPOSE:To perform a registration correction with a high resolution by calculating a signal which interpolates the deviation of registration from the signals in arranging elements whose positions on corresponding light receiving planes are neighbored to each other out of the arranging elements of the signal of two fields outputted from each image pickup element successively. CONSTITUTION:Light passing an optical lens 1 and a prism 2 is converted into an electrical signal by a solid-state image pickup element 3, and is separated to the arranging elements at every output signal, and they are stored once in a video signal memory circuit 4 of N-lines. Meanwhile, the signal of one field outputted at a preceding field is stored in a field memory 13 in advance. At a registration deviation correction circuit 5', four adjacent element points (MXN points, generally) are taken out from the arranging element of a video signal of two fields, and a value at a predicted registration deviated position a' is found by interpolating by using the values of those element points. And by setting its compensation signal as the signal at a corresponding correct arranging element position (a), a chrominance signal Sr in which the registration deviation is corrected is outputted. In such a way, a video signal high resolution can be obtained.

Title: Liquid crystal spectacles
Inventor: YAMAMOTO HIROYUKI
IPC: G02C7/06
Filed: 1985-02-01
Abstract: PURPOSE:To suppress the power consumption of liquid crystal spectacles, by using liquid crystal lenses which are set at the usually most used focal distance under a condition where the power supply is cut off or a condition very close to the condition. CONSTITUTION:Liquid crystals 11a and 11b are set at a focal distance at which an object at the usually most used distance can be observed clearly together with a convex lens 8 at the center and concave lens-like liquid crystal lenses 12a and 12b at both sides under a condition where no AC voltage is applied. When a condition which cannot be covered by a state where no voltage is applied, such as a case where a very close object is observed, and so forth, the AC voltage is applied by turning on a switch 17. Then molecules of the liquid crystals 11a and 11b rise in the vertical direction from the oriented condition in parallel with transparent plates 10a and 10b and refractive indexes of the liquid crystals 11a and 11b to abnormal lights become smaller. Therefore, the focal distance of the entire concave lens becomes longer and any object nearby can be observed clearly. When a very far object is to be observed, the power consumption can be reduced, because the time for observing the object is not usually long.
