Title: Differential gear
Inventor: INOUE MAKOTO
IPC: F16H48/06
Filed: 1983-10-07
Abstract: PURPOSE:To uniformize the gear contact patterns made between a ring gear and a transmission side gear by a method wherein the rigidity of a gear mounting part in a differential gear case is made as uniform as possible in the direction of rotation. CONSTITUTION:The rigidity of at least either one out of the flange 410 of a differential gear case 400 and the inward flange of a ring gear 420 is made less rigid than the rigidity in the vicinity of an access opening 404 so as to make the rigidity of the differential gear case 400 together with the ring gear 420 uniform. As a result, the rigidity of the ring gear 420 fixed to the differential gear case 400 becomes uniform along the various parts in the direction of rotation, resulting in developing no partial deformation when the rotation is inputted to the ring gear 420 and consequently generating no unsymmetrical wear of the ring gear 420.

Abstract: PURPOSE:To enable the selection of colors without increasing the number of keys by a system wherein a key input means comprising a plurality of keys is made to function as color specifying keys, operating simultaneously as a means to make the keys execute functions assigned primarily thereto. CONSTITUTION:Color specification is made in such a manner that a key signal (k) is read in PB as a color specification code signal. A printed color storage register PA stores a color employed when a printing unit PRT is in a driven state. After a color home signal CH is transmitted from the printing unit PRT to a color selection circuit CS and thereby a first color is selected, the sort of color is shifted by the number of times of inputs of a color shift signal CP and thereby it is selected. The color shift signal CP is outputted to PRT until a coincidence circuit CC detects the coincidence between registers PA and PB, and after a color specified by the register PB is selected, a printing instruction etc. are transmitted from a control circuit CPU to the printing unit. Consequently, printing is conducted with a printing color specified by a keyboard KB.

Title: Liquid crystal element
Inventor: MOMOSE YOICHI
IPC: G02F1/1335
Filed: 1986-08-13
Abstract: PURPOSE:To increase the transmissivity in an ON state and to make a liquid crystal element easy to see by forming a polarizing layer only on the light incidence side of a cell and forming a reflecting layer on its opposite side. CONSTITUTION:The polarizing layer 7-1 which only polarizes light incident on the cell is formed only on the light incidence side of the liquid crystal layer 8 of the cell, and the reflecting layer 6 which reflects light transmitted through the liquid crystal layer 8 is formed only on the opposite side of the cell from the side where the polarizing layer 7-1 is formed. Thus, the polarizing layer 7-1 is formed only on the light incidence side of the cell and allowed to serve as an analyzing layer, and then the light incident on the liquid crystal element passes through the polarizing layer 7-1 only twice before being reflected by the reflecting layer to exit from the liquid crystal element, so the light absorption of the polarizing layer 7-1 is less than a conventional liquid crystal element. Consequently, the transmissivity in the ON state is high and the easy-to-see liquid crystal element is obtained.
