IPC: G09G1/00
Filed: 1984-07-17
Abstract: PURPOSE:To check a layout while inputting a Japanese sentence and to reduce the device at its cost and size by forming a picture mode switching means, a picture mode decision means, a contraction pattern generating means, etc. CONSTITUTION:When a contracted picture is to be switched to a normal picture, a contraction mode is switched to a normal mode by the picture mode switching means 1 and a normal picture is displayed on the whole display screen. Then, the picture mode decision means 2 decides the mode and a character pattern is generated and displayed in accordance with the mode. In case of switching the mode to the contraction mode and displaying a contracted picture, a contracting pattern is also prepared in addition to the normal pattern. The display screen is divided into four sections, which display a part showing the layout, the character pointed by a cursor at present, a Japanese sentence initially inputted with ''kana'' (Japanese syllabary), and a simple picture information.

Title: Displacement sensor
Inventor: KAWASAKI KATSUYOSHI
IPC: G01D5/20
Filed: 1990-06-08
Abstract: PURPOSE:To improve detecting capability with a simple constitution without the large increase of the cost by arranging a nonmagnetic member which is a conductor and a magnetic conductor in the advancing and backing directions, and constituting a core. CONSTITUTION:A cylindrical sleeve 7 whose relative displacement in the axial direction and the turning direction is free is coupled to an input shaft 2. The sleeve 7 has a flange part (core) 7c which is continued in the circumferential direction. Both surfaces of the core 7c which face the advancing and backing directions of the sleeve 7 of a nonmagnetic ring 10 that is a conductor are held by magnetic rings 11a and 12. The permeability of the nonmagnetic body is similar to that of air and smaller that the permeability of the magnetic body. Meanwhile, when the magnetic flux is intersected with the conductor, an eddy current flows so as to hinder the change in magnetic flux. Therefore, the nonmagnetic ring that is the conductor has the property which is hard to pass the magnetic flux more than the degree of the air. In this way, the changing width of the outputs of receiving coils L2 and L3 with the advance and backing of the core 7c becomes larger in comparison with the case wherein the core 7 is formed of only one magnetic body.
