Patent JP-H03121383-A (JP)
Title: Magnetic valve
Inventor: HORUGERU NIKORAISEN
IPC: F25B41/06
Filed: 1990-09-14
Abstract: PURPOSE: To seal more satisfactorily in a closed state by providing a valve plate with an annular resilient metal plate having teeth protruded at least at the inner edge, and a coating of elastic plastic sprayed onto the annular plate in such a way as to leave the teeth uncoated. CONSTITUTION: An elastic plastic coating 28 cooperates with a thin annular plate 25, particularly with the elastic flexibility of teeth of small cross section, to more easily conform to unevenness of a valve seat and/or to more easily compensate the oblique position of a valve plate 15 caused by the inclination of a valve shaft 13. Sufficient sealing is therefore attained in a closed state. Unevenness of the valve plate 15 caused by vapor shut up between an annular support plate 25 and the coating 28 and a consequent leak is also prevented since the shut-up vapor is released to the atmosphere by the exposed surface of the teeth.

Title: Liquid crystal display element
Inventor: NAKAO KENJI
IPC: G02F1/13
Filed: 1994-10-12
Abstract: PURPOSE: To drive the element with a low voltage by sealing the composite of the polymer material and liq. crystal material between substrates and changing the arrangement of the liq. crystal material close to the polymer material boundary with respect to the polymer boundary in a specified direction with temp. CONSTITUTION: A composite material, in which an almost globular liq. crystal 14 is dispersed in a polymer 13, is held between two substrates 11 each having a transparent electrode 12. The tendency for the molecules of the liq. crystal 14 close to the polymer 13 boundary to arrange almost vertical to the polymer boundary is changed to the tendency to arrange almost horizontal to the polymer boundary with a temp. change. The transition temp. should be in the working temp. range of the liq. crystal display element, and the average diameter of the globular liq. crystals 14 is preferably controlled to >=1.2μm. Consequently, the driving voltage is lowered, the scattering intensity is increased, and a good display is realized.

The heat transmitted to the tube 15 expands an operation medium sealed in an operation space which is formed by linking an expansion space 16 and a compression space, a piston 23 is pushed out, and an engine 10 is started. And the current flow from the solar cell 30 to the heating plates 21 is controlled by a control device 32 which has received the temperature of the plate member 18 from a sensor 31 on the plate member 18 as a signal.
