IPC: C25F3/12
Filed: 1991-11-14
Abstract: PURPOSE: To provide etching anisotropicity in the new degree of freedom regardlessly of a crystal azimuth, by irradiating p-type added silicon at an etching stop potential with the light of a specified wavelength and starting an etching process.

Title: Purge receiving device
Inventor: SATO TAKAHIRO
IPC: B29C45/17
Filed: 1990-11-05
Abstract: PURPOSE:To make it possible to prevent even highly viscous resin from sticking to a purge receiving member, which receives the resin injected from an injection nozzle and drops it, by a method wherein one end of the purge receiving member is fixed and its other end is set free so as to make the member vibratile or swingable. CONSTITUTION:Of a purge receiving member 18, the part to be pinched 20, which is fixed to a purge receiving device 14 by being pinched, is formed at its upper end, while its lower end is set free. A purge receiving face 22, which is formed at the lower end of the purge receiving member is coated with 'Teflon(R)'. At the middle of the purge receiving member 18, a roundly swollen spring part 28 is formed so as to make the purge receiving member 18 vibratile, when external force is applied to the purge receiving face 22. When resin 16 is injected, the resin 16 pushes the urge receiving face 22 against the elasticity of the spring part 28 in the direction as indicated by an arrow B by means of injection pressure. After that, when the injection of the resin 16 comes to an end or the injection pressure lowers below the elastic force of the spring part 28, the purge receiving face 22 comes back to the direction opposite to the direction indicated by the arrow B, resulting in vibration as indicated by an arrow C. Due to the gravitational force and said vibration, the resin 16, which tends to stick to the purge receiving face 22, can be peeled off the face and dropped.

IPC: H04N5/335
Filed: 1992-10-13
Abstract: PURPOSE:To reduce generation of a flare without decreasing sensitivity and to diminish an irregularity in the sensitivity. CONSTITUTION:A groove 23 is formed on a region except a photosensor 11 of a planarization film 17 covering a shielding Al film 16, etc., and a black-dyed layer 21 is provided as a reflection preventive layer only in the groove 23.
