Abstract: PURPOSE:To reduce load to the bearing surface greatly and make a bearing in smaller size by installing a bearing to receive both a radial and a thrust load at the shaft penetrating part of the casing and leading the own discharge water back to the suction chamber as lubricant water. CONSTITUTION:At the shaft penetrating part on the shaft joint 13 side, a bearing 4 to receive radial load is furnished to introduce the high pressure water from the discharge part 6 to the periphery of said bearing 4 through a conduit 7, whereafter this water is sent into the gap against a shaft sleeve 15 through a through hole 14 to act there as a lubricant and coolant and, then, is returned to the low pressure part 9 on the suction side. On the counter shaft joint 13 side, two faces are provided - i.e., a bearing to receive the radial load and a thrust bearing 11 to receive thrust load with its end face. According to this arrangement, water lubrication is performed there and the thrust force in either direction to the right or left is received which is produced by the hydraulic umbalance, so that the pump can be made in small size, the reliability enhanced and manufacturing cost suppressed.

Title: Monaural picture appreciating method and instrument using change of optical angle
Inventor: MASUKANE TOSHIO
IPC: G02B27/22
Filed: 1985-05-15
Abstract: PURPOSE:To draw out depth sense or solid sense through a single-eye observation by bending an optical path from an observation point to an eye by an optical path changing body arranged in front of one eye at least out of right and left eyes and reducing the optical angle so that light rays are made to incident on both the eyes as almost parallel rays. CONSTITUTION:When an observation point X on a picture plane 4 is observed by using prisms 1,,2, light rays emitted from the point X reach the right and left eyes R, L through optical pathes 6, 5 refracted like a V-shaped by the prisms 2, 1 respectively. At that time, the optical angle formed by the right and left visual lines becomes acute angleLX'R coupled with the back point X' and is reduced less than the original optical angle obtained when the point X is observed directly without using the prisms 1, 2. The reduction of the optical angle backs the distance between eyes sensing on the basis of the optical angle and the picture plane 4 up to a position 4' at the same visual angle, so that the freedom of distance sense is obtained in respective parts of the picture in accordance with the combinations of respective discriminating elements. If the instrument is designed so that the optical angle is 0 deg., i.e. right and left visual lines are made parallel, far and near discrimination due to the optical angle is removed and the far and near discrimination almost equal to single-eye observation can be obtained by easy both-eye observation.
