Title: Light emitting source tracking device
Inventor: ISHISE TOSHIAKI
IPC: G01S3/786
Filed: 1989-12-28
Abstract: PURPOSE:To track a light emitting source at a wide view angle with a simple mechanism by directing one of partial spaces, which are divided by a plane to be determined by a rotary axis for control and a collimation axis, by the normal vectors of respective photodetection sensors. CONSTITUTION:Photodetection sensors 8a and 8b, which are sensitive for an output change caused by an incident angle, are arranged while being inclined only at a suitable angle phion the both sides of a reference axis 13 so that a collimation axis 13 of a photodetection lens 9 for optical communication can be an objective axis. Then, the outputs of these photodetection sensors 8a and 8b on the both sides are compared and the collimation axis 13 is always rotated in the direction of the larger output. Namely, when observing from the collimation axis 13, angles to be formed by incident light 12 coming from the direction of the partial space on a rectangular side, photodetection surfaces of the left and right photodetection sensors 8a and 8b and a normal 11 are defined as theta1 and theta2 and angles to be formed by incident light 12' coming from the direction of the partial space on the left side, the photodetection surfaces of the sensors 8a and 8b and the normal 11 are defined as theta1' and theta2'. In such a case, when the incident light comes from the right side of the collimation axis 13, the condition of theta1 > theta2 is established and a rotating motion occurs on the right side. When the incident light comes from the left side, the condition of theta1' < theta2' is established and the rotating motion to left is executed.

Title: Lamination type cathode device
Inventor: SANO KINJIRO
IPC: H01J1/22
Filed: 1989-12-26
Abstract: PURPOSE:To improve reliability of the welding part between a lead wire and a pin and reduce the dispersion of cut-off voltage by supportedly connecting a heat-resistant insulating substrate to a cathode pin and a lead wire L-shapedly folded to a heater pin. CONSTITUTION:A heat-resistant insulating substrate 1 is supportedly connected by means of cathode pins 7, plantedly erected on a cathode vessel 6, and lead wires 9 L-shapedly folded to heater pins 8. Here the lead wires 9 are welded to the heater terminals 53 and the cathode terminals 31 on the substrate 1. The application of voltage to a heating body 51 causes the heating body 51 to be heat-generated by Joule heat, the substrate 1 to be heated, and the heating of substrate metal 2 to high temperature causes barium oxide, which is a component of an electron radiation substance 4 layer, and the substrate metal 2 to make reaction to conduct electron radiation with Ba, produced by the reaction, as a donor. This high temperature action causes a lead wire 6 to rise to high temperature to make thermal expansion, but because the lead wire 6 is displaced to a dotted line shown condition, the stress to the welding point of the heater pin 8 or the cathode pin 7 is relaxed. This permits reliability improvement of the welding part and reduction of the dispersion of cut-off voltage.
