Title: Brake boosting device
Inventor: WATANABE MAKOTO
IPC: B60T13/52
Filed: 1991-02-26
Abstract: PURPOSE:To simplify the installation work by providing only one negative pressure introducing pipe in a negative pressure type brake boosting device. CONSTITUTION:A bellows 38 is arranged in a constant pressure chamber A, and one edge of the bellows 38 is connected with the edge part of the first constant pressure passage 24 formed on a valve body 8. The other edge of the bellows 38 communicates to a negative pressure source through a negative pressure introducing pipe 25, and a solenoid valve 42 for allowing the inside space A' of the bellows 38 to communicate to the atmosphere if necessary is installed between the negative pressure introducing pipe 25 and the negative pressure source. Further, since a check valve 43 is installed in the bellows 38, the communication of the negative pressure from the inside space A' of the bellows to the constant pressure chamber A is permitted, and the communication of the atmosphere from the inside space. A' of the bellows 38 to the constant pressure chamber is suppressed. With this constitution, it is enough for a conduit for connecting the negative pressure source and a brake boosting device to have only one negative pressure introducing pipe 25.

Title: Magnetic recording medium
Inventor: KOMI FUMIO
IPC: G11B5/64
Filed: 1985-03-19
Abstract: PURPOSE:To improve the corrosion resistance of the titled medium by providing a plasma-polymerized protective film layer on the magnetic layer formed on a substrate. CONSTITUTION:A plasma-polymerized protective film layer 9 contg. sulfur is formed on a magnetic layer 8 to form cross linkages with the sulfur atom as a nucleus, hence the cross-linking density of the plasma-polymerized film layer 9 is increased and the corrosion resistance is sufficiently improved. The plasma-polymerized protective film layer 9 is formed by exposing the magnetic layer 8 to the plasma of the gaseous monomer of an org. compd. contg. sulfur or the gaseous mixture of the org. compd. monomer and another org. compd. monomer and performing plasma polymerization. Since the plasma-polymerized protective film layer 9 contains sulfur atoms capable of forming up to 6 linkages per atom, the cross-linking density of the plasma-polymerized film layer 9 is increased, water and air are hardly permeated and the magnetic recording medium with sufficiently improved durability can be obtained.

Abstract: PURPOSE: To optimally design a mechanism and a mechanism parameter by formulating the relationship between a manufacturing error of the mechanism parameter and positioning accuracy by using a geometric quantity of Riemann geometry in order to design an automatic positioning mechanism hardly influenced by a manufacturing error of the mechanism parameter. CONSTITUTION: When a certain mechanism is designed, a positioning point is expressed as a function of various mechanism parameters, and its microscopic changing quantity (an error) is expressed by an expression (a line element) using a basic tensor of Riemann geometry, and a mechanism is evaluated by using curvature or the like calculated from its basic tensor, and a mechanism by which a manufacturing error of the mechanism parameter hardly influences positioning accuracy is designed by repeating this. Therefore, various quantities of Riemann geometry are calculated, and influence on positioning accuracy by a manufacturing error of the mechanism parameter is evaluated, and a mechanism by which a manufacturing error of the mechanism parameter hardly influences positioning accuracy can be optimally designed without performing an accuracy test by manufacturing an actual mechanism.

Title: Optical element
Inventor: NISHIMURA YUKIO
IPC: G02F1/19
Filed: 1985-03-22
Abstract: PURPOSE:To obtain an optical modulating element of high quality which has a wide visual angle and superior articulation and causes no eye fatigue by sandwiching a gel layer which scatters light when heated and transmits light when cooled between a transparent substrate and a transparent protectionlayer. CONSTITUTION:The gel layer 2 sandwiched between the transparent substrate 1 and transparent protection plate 3 has its distribution of polymer molecule chains divided into a rough and a close area in a low temperature state, and incident light 6-1 to the low-temperature is scattered. When the layer 2 is heated by being irradiated with an infrared beam 5 according to an information signal, the incident light beam 6-2 to the heated area 4-1 is passed through the layer 2 as it is and reflected regularly by the surface of the substrate 1 because the distribution of molecule chains is uniform. Thus, a sharp, high-resolution image with high contrast is obtained and there is no eye fatigue; and the visual angle is not limited and the power consumption is reduced.
