Title: Pressure control valve
Inventor: TANAKA HISASHI
IPC: F16K47/08
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a pressure control valve capable of improving a flow rate characteristic without using a siphon tube for a feed-back passage connecting the secondary side port of a passage to a feedback room. SOLUTION: In order to allow the secondary side pressure outputted from a secondary side port 4 to approach a set pressure, deterioration in the pressure sensitivity of a valve body 7 is reduced by holding the inner pressure of the feedback room 25 at a level lower than that of the port 4. In this embodiment, a level difference is formed on a passage 2 by forming a projection part 37 on the immediate upstream side of an aperture part 27a of the passage 27 connected to the room 25 to generate negative pressure around the aperture part 27a. Thereby the inner pressure of the room 25 can be reduced lower than the secondary side pressure without using a ciphon tube. Since a rectifying filter 38 is arranged on the downstream side of the level difference, pulsations of fluid which may easily occur under negative pressure can be prevented.

Title: Optical recording element and liquid crystal composition used therefor
Inventor: KAJIYAMA CHISATO
IPC: G02F1/13
Filed: 1991-02-28
Abstract: PURPOSE:To make very fine image display possible by writing with light illumination under application of electric field to a liquid crystal element in which a liquid crystal composition made of high molecular and low molecular liquid crystal compound with an addition of light responsive substance is used as its material. CONSTITUTION:A liquid crystal composition for forming a smectic phase composed of high molecular and low molecular liquid crystal compounds is sandwiched between transparent electrodes to form a liquid crystal element to which an electric field is applied. The frequency characteristic of the light transmissivity of liquid crystal elements varies according to the composition of the liquid crystal. If a light responsive substance is added to the liquid crystal composition, the light responsive substance makes reaction by light irradiation and the composition of the liquid crystal composition changes. Namely the frequency characteristic of the liquid crystal composition for the light transmissivity is changed by the light radiation. Noting the portion where the light transmissivity changes suddenly, if an electric field is applied at a certain frequency and further a light beam is radiated to a part of that area, the light transmissivity in that part changes. As a result, an image can be displayed without being disturbed by natural light.
