Title: Electron gun structure for image pick-up tube
Inventor: MIYAMOTO SATORU
IPC: H01J29/48
Filed: 1982-05-12
Abstract: PURPOSE:To improve reliability by shutting completely stray beams inside of a G2 electrode in order to prevent a mesh electrode from influefce of leakage beams. CONSTITUTION:A cylindrical metal member 30 fixed to a beam limiting plate 22 by spot welding or the like is fitted so as to reduce a gap d1 to a G2 electrode 8 as much as possible. The gap d1 varies to the thickness of the cylindrical metal member 30 whereby in the case of the thickness 0.5mm., the gap of around 0.1mm. brings in the full effect. In this way, electron beams entering through holes 8a of the G2 electrode 8, even when these reflect, loose their speed energy because of repeated reflection inside of the electrode 8 and consequently eliminating reflection beams outside of the cylindrical member 30 by means of fitting said member.

Abstract: PURPOSE:To reduce the number of constitutional parts and to simplify assembling work by integrally molding the spacers provided to the respective parts loaded with no electronic parts on both main surfaces of a printed circuit board along with a frame. CONSTITUTION:Spacers 60 are integrally formed to a frame 40 corresponding to the empty spaces loaded with no electronic parts 3 on a printed circuit board 2. By preliminarily integrally forming the spacers 60 to the frame 40, in other words, by forming the frame 40 integrally containing the spacers 60, work for positioning the spacers or fixing the spacers to the printed circuit board 2 by an adhesive sheet becomes unnecessary and assembling work can be simplified. Further, since the spacers 60 become a part of the frame 40, the number of parts can be reduced. The shape and number of the spacers 60 can be freely altered corresponding to the number of the empty spaces and the loading state of the electronic parts.

Title: Optical transmitter
Inventor: HANAWA HIROAKI
IPC: H04B10/60
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To attain optimization processing of driven data that suppresses effective extinction and a delay in light emission against a characteristic degradation in a laser diode so as to keep an optical output contact without the need for a special experience rule. SOLUTION: A control means 170 that detects a characteristic degradation in a laser diode 100 as a fault in a modulation current, increases a bias current by a prescribed current each to control the drive data in a way of decreasing the modulation current without changing the entire drive current supplied to the laser diode causing a delay in light emission in this state. The laser diode may soon cause defective extinction because the bias current exceeds a threshold current as a result of repeating this processing. The modulation current and the bias current just before a change point of the defective extinction detected on the basis of the delay in light emission indicate a current denoting the degraded characteristic of the laser diode with fidelity or closely thereto. This current is adopted for an optimum drive current.

Filed: 1984-04-19
Abstract: PURPOSE:To hold the load electric power of the lamp constant even if an input source voltage varies by comparing an effective value calculated by detecting a lamp current with a reference value and controlling the lamp current on the basis of the comparison output. CONSTITUTION:An effective value calculating means 11 detects the lamp current i(t) of the lamp 22 to calculate the effective value I. A lamp resistance varies in value greatly with filament temperature, but considered to be nearly constant when the lamp is on almost at the rated electric power point, so the lamp electric power is expressed as the product of the square value of the lamp current and resistance value. For the purpose, the lamp current is controlled to a constant value as long as the resistance value. Then, a comparator 112 compares the effective value I with the reference value I0 and outputs their difference, and a phase control means 113 controls the phase of the current i(t) on the basis of the difference output to hold the load electric power of the lamp constant.
