Title: Electron beam device
Inventor: KOBAYASHI HIDEKI
IPC: H01J37/04
Filed: 1982-11-29
Abstract: PURPOSE:To detect that more than allowable amount of electron beam is impinging around an orifice through simple and rigid structure, by providing a vacuum gauge. CONSTITUTION:A vacuum gauge 10 is provided above and near to an orifice 6 to detect pressure rise (deterioration of vacuum) due to gas emitted from metal body (copper, aluminum, iron, etc.) around orifice through shock heating function upon impingement of more than predetermined amount of electron beam against the orifice.

IPC: B29C65/42
Filed: 1983-11-07
Abstract: PURPOSE:To enable to secure a stator without limiting the viscosity of an adhesive without rubbing off the adhesive by press-fitting the adhesive between a stator supporting member and a stator clamper. CONSTITUTION:When an adhesive is filled from an adhesive filling port 5, gaps between a stator supporting member 3 and a stator clamper 13 at both sides of a slot 131 are very small, and the press-fitted adhesive arrives at a band 132 through the slot 131. Further, the adhesive might sometimes expand externally from between the member 3 and the clamper 13. Since the adhesive is disturbed by the band 132 at this time, it does not flow directly clockwise to an exhaust port 32. Blocking pins 5, 6 are hitted to the ports 31, 32 to finish the securing work of the stator.

Title: Cassette loader
Inventor: ANDO TAKASHI
IPC: G11B15/675
Filed: 1986-09-05
Abstract: PURPOSE:To smooth a discharging motion by providing the guide groove wall having a continuous curved face so that a cassette holder may be given the moving locus smoothly at the inflection point composed by 1st and 2nd guide groove parts formed on both side wall members respectively. CONSTITUTION:When a cassette holder is discharged from a 2nd position to a 1st position, the driven side is ascended slightly delaying for the driving side when the cassette holder comes to the inflection point by the driving side arm. The guide pins 36, 37 playing the role of a guide in the vertical direction and horizontal direction attain in the state of stopping at the inflection point, irrespective of the pins 33-35 at the driving side passing through the inflection point 49, and the cassette holder 28 pinched by the side plate at both sides has a bigger sliding resistance even if the guide pin 33 is driven by a driving arm 43 and a smooth discharging motion is made impossible. However an easy escape from the inflection point 49 is possible with absorbing the phase delay by making the curvature of the inner side wall 50 of the inflection point 49 of the L-shaped guide groove provided at the driven side larger than that of the driving side.

Title: Color picture tube
Inventor: OTAKE YASUHISA
IPC: H01J29/07
Filed: 1993-08-25
Abstract: PURPOSE:To allow only a desired electron beam to pass through an opening by forming an angle formed by a straight line along a ridge line from an opening end on an electron gun side toward the thickness direction of a shadow mask and the axis of an opening larger than a specific angle. CONSTITUTION:An angle alpha formed by a straight line 35 along a ridge line from a small hole end 321 toward a ridge line mating portion 34 and the axis 36 of an opening is set larger than an angle gamma formed by a straight line 38 connecting a large hole end 311 to a contact point 39 near the mating portion 34 and the axis 36 of the opening. An electron beam 33 passing from a small hole 32 side of the opening toward the large hole 31 side reaches a fluorescent screen 42 without collision against a side wall of the opening, and further, a passing quantity can be secured. A diameter of the beam 33 passing through the electron beam opening is substantially identical to the dimension of the small hole of the opening. Consequently, control of the dimension of the opening of the beam 33 allows the diameter of the beam 33 reaching the fluorescent screen 42 to be controlled. Even if a reflection electron beam is generated inside the opening, it cannot reach the fluorescent screen 42, thus obtaining a screen of high quality.
