摘要： PROBLEM TO BE SOLVED: To easily apply an optical system correction system to a projector for home use by realizing miniaturization and cost reduction and securing an excellent operation feeling.
SOLUTION: A trapezoid correcting device for projector which corrects trapezoidal distortion of an image projected on a screen by displacing a projection lens laterally and/or longitudinally is equipped with a support mechanism part which has a mechanism for guiding a support part of the projection part laterally and/or longitudinally, an operation part which is manually operated, and a transmitting mechanism part which transmits the manipulated variable of the operation part to the support mechanism part through a gear mechanism including at least a rack and pinion to displace the lens support part laterally and/or longitudinally.

摘要： PROBLEM TO BE SOLVED: To enhance cooling effect and uniformity of light while avoiding an increase in the size of the whole of a projector and an increase in the amount of noise.
SOLUTION: A light pipe cooler 1 for the projector P for cooling the light pipe 2 for uniformizing the light L passing an optical path S of the pipe formed by reflection mirrors M etc., is provided with: a hermetically closed casing 3 which has a light inlet surface section 3i and a light outlet surface section 3o both transparently formed, has the light pipe 2 inside and houses a transparent liquid 4; and a cooling means 5 which cools the transparent liquid 4. Irregular reflection granular materials 11 which irregularly reflect the light L by floating can be incorporated into the transparent liquid 4 at a prescribed ratio to the transparent liquid 4.

摘要： PROBLEM TO BE SOLVED: To decrease the kinds of the identification data so as to decrease the length of the required identification data in an optical disk medium the recording data of which are managed by identification data in the unit of frames. SOLUTION: In this method, 4 kinds of frame management data is defined to identify 26 frames. Recording 4 kinds of the frame management data to the optical medium in a predetermined sequence, the length of the management data can be minimized while identifying the frames.
摘要翻译：要解决的问题：为了减少识别数据的种类，以减少其记录数据以帧为单位由识别数据管理的光盘介质中的所需标识数据的长度。解决方案：在这种方法中，定义了4种帧管理数据来识别26帧。以预定的顺序将4种帧管理数据记录到光学介质中，可以在识别帧的同时最小化管理数据的长度。
