Filed: 1984-05-16
Abstract: PURPOSE:To eliminate oscillating the whole pickup at highspeed and to detect a track on push-pull basis by providing a means which detects deviation when a lens system is moved and to correct DC deviation due to the movement.

Filed: 1979-07-31
Abstract: PURPOSE:To know the state of a substance to be analyzed by accurately measuring the Raman spectrum of a part very close to the surface of the substance by using sapphire as an internal reflective element plate. CONSTITUTION:Sapphire-made internal reflective element plate 2 is brought into close contact with transparent substance 1 and laser light 3 is caused to strike internal reflective element plate 2.

IPC: B29C45/56
Filed: 1987-04-23
Abstract: PURPOSE:To enhance the production efficiency of a disc and obtain a good quality molded item by a method wherein an ejector pin is ejected before the resin in a sprue solidifies in order to compress the resin and, after mold opening, the ejector pin is ejected again so as to remove the sprue. CONSTITUTION:An ejector pin 11 waits at a position far retreated from the bottom of a cold slug well 10. At this time, a sprue 14 is set to develop a bubble under vacuum 15 and sinking. Next, the ejector pin 11 is advanced to the bottom of the cold slug well 10. Since the sprue 14 is pressurized by the above- mentioned advancement of the ejector pin, neither vacuum bubble 15 nor sinking develop at the solidification of the sprue 14. The sprue 14 firmly bites the cold slug well 10 and does cot come out. After that, the ejector pin 11 performs a second stage action so as to forcibly eject the sprue 14, which firmly bites the cold slug well 10. By employing the above-mentioned method, no bad effect is given to a product and no clogging of a sprue hole occurs, resulting in enhancing the production efficiency.
