IPC: H04N9/31
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To attain reproducing high optical properties and mechanical properties by preventing an annular light transmissive area from being interrupted by a supporting element and sticking a filter segment to a supporting body in a flat state in a sticking zone which is positioned opposite to a rotary axis and not arranging a through-hole part on the filter segment. SOLUTION: The filter segment 12 is fixed to the supporting body 11 through an adhesive layer 13 so as to form a step on the surface of the supporting body 11. The filter segment 12 is accurately brought into contact with the supporting body 11 in a radial direction 25 and the axial direction 26 by the step part in the supporting body edge part area. The surface adhesion is performed only in an area constituted of a slender annular zone facing opposite to the center of rotation, then, most of the filter segment surface remains as a light transmissive annular effective zone facing outwards in the case of viewing from the rotary axis in the radial direction. Then, the installation of such an additional holding element requiring a through-hole part like a hole as filter segment is avoided.

Title: Push-pull power amplifier
Inventor: YOOGENDORA KEE CHIYAURA
IPC: H03F3/60
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To cancel gain drift as transmitting radio frequency with high electric power by compensating short-term (by the minute) gain deterioration by providing a B+ or drain voltage controller and compensating short-term (by the second) gain deteriorated by providing a voltage controller. SOLUTION: In gain stability, a descending drift of a characteristic curve 1 is progressed along a dotted line from time zero, and the gain deterioration is characterized about a few seconds later. A gain is reduced for a few minutes and then stabilized. The gradual descending drift is called as the short-term (in units of minutes) gain drift and achieved by the so called B+ correction for the gain stability. Then an amount of drain supply voltage Vdd or the B+ is increased, the gain drift is cancelled, and a smooth and stable gain is obtained. Then, the short-term (in units of seconds) gain drift which is the descending drift with much gain is due to heating of an equipment die, caused by equipment dielectric during power transmission. The correction is performed by increasing the gain of a linear stage of an amplifier 26 to the short-term gain drift.
