Title: Improvements relating to automatic steering gear
IPC: G01C17/00
Filed: 1939-01-11
Abstract: 530,437. Magnetic compasses. GENERAL ELECTRIC CO., Ltd., and CHANCE, B. Jan. 11, 1939, No. 935. Drawings to Specification. [Class 97 (ii)] [Also in Group XXXV] To correct errors in a magnetic compass due to the influence of the craft's roll an automatic steering gear, comprising photo-electric means of rudder control actuating also follow back mechanism restoring the light and photo-cells to neutral relationship, controls also means for producing an electromagnetic field in the neighbourhood of the compass in accordance with the velocity of rolling of the craft. These means are preferably mounted on the hollow back element and are energized by pick-up coils sliding over one of the permanent magnets correcting transverse compass error when the craft rolls. An amplified voltage generated by each coil is applied to the grid of a thermionic mixer valve, another grid of which receives the voltage from the photo-electric cell. Correction is thus only made when the compass is in error and is interrupted when completed, so that a large correcting influence may be applied. Specification 528,174 is referred to.

Abstract: PROBLEM TO BE SOLVED: To provide a bearing for high speed rotation with durability by exposing a basic material internally and composing the peripheral surface of the oxide of basic material and obtaining a bearing utilizing the dynamic pressure groove in a rotary shaft, a part of housing facing the rotary shaft or a part of rotor. SOLUTION: Prior to formation of an oxide layer, a rotary shaft 4 is applied with a mask 9 in the form of dynamic pressure groove 6 and then the surface is oxidized to form an oxide layer 10. When the mask 9 is stripped, a recess is left because the oxide layer is not formed. It is used as a dynamic pressure groove 6 and the basic material is exposed at the bottom. Consequently, the oxide layer and dynamic pressure groove can be formed simultaneously through hardening process without requiring the grinding process at all thus reducing the labor and process. Furthermore, even if the housing or rotary shaft is made of a soft material, it can be protected against damage by performing the hardening process on the surface.
