Title: Video display device
Inventor: OSAWA SATOSHI
IPC: G06T19/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To obtain a video display device capable of 3D (stereo-scopic) video display with the small quantity of information by projecting a video having a binocular parallax at the centers of the respective right and left visual fields of an observer and projecting a video having no the binocular parallax in the vicinity of the periphery thereof. SOLUTION: A video having a binocular parallax is projected in the vicinity of the centers of the respective right and left visual fields of an observer and the video having no the binocular parallax is projected in the vicinity of the periphery thereof. Thus, the video having parallax information is projected in the vicinity of the center of a screen and the video having no the parallax information is projected in the vicinity of the periphery by the respective picture display elements displaying the videos for a right eye and a left eye.  Namely, since a human being does not feel a sense of incongruity so much with respect to the video on the periphery of the visual field even without detailed information from the viewpoint of a human sense, the video information is reduced without spoiling the 3D sense of the observer, recording capacity and a transmitting speed are decreased and the cost is reduced.

Title: Rotary head for laser machining
Inventor: MORIKAWA AKIRA
IPC: B23K26/064
Filed: 1987-10-21
Abstract: PURPOSE:To prolong the service life of a condensing optical system and to speed up its working by using a reflection type condensing mirror as the condensing optical system. CONSTITUTION:A laser beam 1 which has been outputted from a laser oscillator is reflected by a first reflecting mirror 2 placed in a supporting lens barrel 10, and the advance direction is deflected by 90 deg.. In a movable lens barrel part 11 which has been coupled so as to be rotatable through a bearing 6 to the supporting lens barrel part 10, a reflection type condensing mirror 12 is placed by inclining it by 45 deg. toward an optical axis of reflected light by the first reflecting mirror 2. The laser beam which has been reflected by this reflection type condensing mirror 12, and also, has been condensed is radiated on a work 5 from the tip of a nozzle 8. Accordingly, since the reflection type condensing mirror 12 has both a reflecting function and a condensing function, a two-storey structure consisting of a reflecting mirror and a condensing lens is eliminated, and length l extending from a rotation axis X of a rotary head to the top of the nozzle 8 can be shortened. As a result, the speed of revolution of a constant speed of the rotary head can be made large, and the working can be executed at a high speed.

Abstract: PURPOSE:To avoid magnetic coupling between a high frequency probe for NMR and another high frequency probe used together with said high frequency probe by constituting a non-projecting part of a device with one or more pairs of conductive segments and inserting a PIN diode to at least one pair of conductive segment. CONSTITUTION:The non-projecting part of this high frequency probe for NMR consists of one or more pairs of conductive elements 11c and 11d, and a PIN diode 12 is inserted to at least one pair of conductive segment.
