IPC: B29C33/10
Filed: 1985-04-04
Abstract: PURPOSE:In molding an optical element by molding method under pressure, to obtain freely an optical element in a desired shape by a simple method using a parallel flat material, by setting grooves on the material before it is molded under pressure. CONSTITUTION:Before a material is molded between the top mold 1 and the bottom mold 2, the grooves 6 (four in the figure) are formed on the peripheral surface of the material 5. The grooves 6 extend at one side of the material and the opposite side in the direction wherein pressure is applied to a mold cavity. When the material 5 thus constructed is put between the molds 1 and 2, pressed and transformed, air existing in the space 4 between the material 5 and the mold 2 is released in the arrow 7 direction and is not closed in it. Since the material constituting the grooves 6 are transformed outward with the transformation of the material 5, parts corresponding to the grooves 6 of the material 5 are transformed until they are shown by the broken lines 8 and the grooves 6 are eliminated when the optical element 9 in a desired shape is molded.

Title: Valve
Inventor: FUJIKAWA TOSHIHIRO
IPC: F16K31/122
Filed: 1985-04-03
Abstract: PURPOSE:To provide a valve which eliminates an O-ring and enables control of high pressure fluid by means of a slight force, by a method wherein a front chamber is communicated with a rear chamber through a communicating passage having a sectional area smaller than that of a side port, and a control valve is situated in the control passage. CONSTITUTION:When pressurized fluid incomes through a stem port 7, a valve body 4 is separated from a valve seat 2 against a spring 12, and the fluid outgoes to a side port 6. When the pressurized fluid is fed through a side port 6 to the stem port 7, a control valve 15 is actuated to open a control passage 14. In which case, a pressure in a rear chamber 11 communicated to the control passage 14 is decreased to a value lower than that of a front chamber 8. This causes the valve body 4 to be pushed in the direction of the rear chamber 11 and separated from the valve seat 2. The fluid flows from the side port 6 to the stem port 7. In case the flow is stopped, the control passage 14 is closed with the aid of the control valve 15. In which case, a pressure in the rear chamber 11 is adjusted to a value equal to that in the front chamber 8 by dint of the pressurized fluid through a communicating passage 13, and the valve body 4 is pressed against the valve seat through the force of a spring 12 to stop the flow.
