Title: Shadow mask for color cathode-ray tube
Inventor: IGARASHI KOICHI
IPC: H01J29/07
Filed: 1993-07-07
Abstract: PURPOSE:To prevent the deformation caused by projectile collision of an electron beam by holding mechanical strength. CONSTITUTION:A shadow mask is composed of a curved surface part 3 composed of a perforated area 1 having a large number of electron beam passing opening holes 8 and a nonperforated area 2 to surround the periphery of the perforated area and a skirt part 4 bent in a frame shape by being arranged continuously on the outer periphery of the nonperforated area of the curved surface part, and almost parallel two recessed shape beads 6 and 6' running around the perforated area 1 are provided in the nonperforated area 2. The width of the recessed shape bead 6 on this perforated area side is made large than the recessed shape bead 6' on the skirt part side. Thereby, a recessed shape on the perforated area side absorbs the deformation in the surface direction effectively, and moves the curved surface part in the panel part direction, and prevents the deterioration of purity.

Title: Image forming element
Inventor: UGA TAKAHITO
IPC: G02B1/111
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To provide an image forming element which prevents the stray light of a luminous flux deviated from an optical axis from affecting an adjacent image forming system. SOLUTION: A part or the whole of the ridge lines of a roof mirror array is formed of a plane or polyhedron or curved surface so as to be able to adjust the direction of the stray light and the degree of scattering as a specular reflection preventive mean at the ridge line parts 2a of the roof mirror array. As a result, the reflection of the stray light at the ridge lines is prevented. When the plane is formed of the polyhedron, the control of the reflected rays of the stray light is possible and if the curved surface is used, the degree of the scattering of the stray light is made adjustable by the bending degree of the curved surface.

Title: Line interruption system
Inventor: HAYASAKA TAKASHI
IPC: H04M11/00
Filed: 1988-07-07
Abstract: PURPOSE:To suppress the addition of charging when an incoming rejection signal is received by using an incoming rejection discrimination section constituting a caller MODEM so as to detect an incoming rejection signal sent from the incoming side thereby interrupting the line. CONSTITUTION:An incoming rejection discrimination section 5 is built in MODEMs 2, 3 and discriminates whether or not a signal replied from the incoming side is an incoming rejection signal. Then based on a data communication command from a terminal equipment (MA) 1, a MODEM (B) 3 receiving ER= OFF (terminal incoming rejection) sends an incoming rejection signal to a line from an incoming side terminal equipment (B) 4 corresponding to the call of the caller MODEM (A) 2 via the line and when the incoming rejection discrimination section 5 constituting the caller MODEM (A) 2 discriminates it to be the incoming rejection signal, even in the communication state, the line is interrupted. Thus, it is possible for the caller MODEM (A) 2 to interrupt the line even in, e.g., the communication state when the incoming rejection signal is received from the incoming side thereby suppressing the summing of charge.
