Title: Light controller
Inventor: SAITO ETSURO
IPC: H04N5/74
Filed: 1995-01-30
Abstract: PURPOSE: To provide a light controller in which a projected image is much more made bright. CONSTITUTION: An actuator 40a is formed by applying etching processing to an actuator board 40 being one metallic board and providing a through-parts 40d, 40e. Furthermore, hinges 40f, 40g are located by the through-part 40e and easily bent. The board 40 is inserted between two glass plates having transparent electrodes corresponding to pixels via a spacer 41. The actuator 40a is displaced by keeping a prescribed potential to the board 40 and generating an electric field with equal absolute value but different sign to the two transparent electrodes. Thus, the reflected light of the actuator 40 is controlled. Since the hinge parts 40f, 40g are specified for the actuator 40a and driven in a push- pull way, the actuator 40a is displaced linearly.

Inventor: WATANABE TOSHIHARU
IPC: B29C45/16
Filed: 1987-02-18
Abstract: PURPOSE:To obtain a high quality and stable in-mold molded item by a method wherein foil material is set in a mold, and the mold is clamped and then under the condition that proper pressure is applied into a cavity, molding synthetic resin material is filled in the space of the cavity so as to leave somewhat room to occupy and, simultaneously with the completion of filling, the pressure is brought back to the ordinary atmospheric pressure. CONSTITUTION:Foaming agent is uniformly mixed in advance with molding synthetic resin material 3. After a mold A is clamped, a pressure of about 20kg/cm<2> is applied to the cavity C of empty part in the mold A. After that, the molding resin material 3 mixed with foaming agent is filled in the cavity C so as to occupy about 95% of the space volume of the cavity C. Simultaneously with the completion of the filling, a valve 4 is opened so as to release the pressure and to bring back the pressure in the cavity to the ordinary atmospheric pressure. During the process, in the mold A, cooling starts at the contact surface between the mold and the filled resin material and simultaneously foaming phenomenon develops in the molding synthetic resin material 3 mixed with foaming agent, resulting in foaming so as to fill the cavity C.
