Title: Cathode structural body of magnetron
Inventor: OGURA TOSHIO
IPC: H01J23/15
Filed: 1990-04-27
Abstract: PURPOSE:To prevent the stress-breaking of a sealing part owing to stress by carrying out barring process to a bottom plane penetrating hole in the bottom plane of a stem for a lead wire in the side to be connected electrically to the bottom plane of a stem choke, to project it toward the stem side, butting the tip part of the barring part to a relay terminal plate, and soldering them with a hard solder to support the stem choke. CONSTITUTION:A lead 1 in a high melting point metal tube which supports a cathode filament is intermediately connected to an outer lead 3 through a terminal plate 2 soldered with a metallized part of a plane of a stem insulator 5 in the vacuum side of the tube by a hard solder and here the tube is sealed in vacuum and air-tight condition. Meanwhile, to suppress leakage of microwaves transmitted by the lead 1, the stem choke 4 is connected with only one of the lead 1 in the tube, and a barring part 4a is so formed in a hole of the bottom plane into which the lead 1 penetrates as to project toward the stem side and its tip part and the terminal plate 2 are joined together. Consequently, the relay terminal plate and the sealing part of the stem insulator 5 do not receive thermal stress from the stem choke 4.

Abstract: PURPOSE:To contrive the improvement in the high frequency characteristics of the semiconductor device by employing an N type low density buried layer inserted of an N<+> type high density buried layer and lowering the collector series resistance of a tripple diffused PNP type transistor. CONSTITUTION:An N type emitter 11, a P type base 12, an N<+> type collector buried layer 13 and an N<+> type collector connection layer 14 are formed sequentially on an NPN type transistor by tripple diffusion. On the other hand, an N type buried layer 5 is low density at the PNP type transistor side, and is lower density than the P type buried layer. Further, the layer 5 is formed in different step of forming the layer 13. According to this configuration, the carrier total amount of the layer 4 is not intruded by the layer 5, and the collector series resistance of the PNP type transistor can be lowered. On the other hand, the NPN type transistor has lower collector series resistance than the layer 13. Thus, both incorporate low collector saturated voltage and can increase the gain band width, and accordingly contrive the improvement in the high frequency characteristics of the IC.

Title: Range finding device
Inventor: SASAKI TOYONORI
IPC: G02B7/32
Filed: 1984-06-01
Abstract: PURPOSE:To prevent chattering generated during ladder resistance switching and also a noise and malfunction due to the floating of a slider by connecting a high resistance between the terminal at one limit position of a ladder resistance and a common terminal. CONSTITUTION:When a photographic lens moves in a direction N infinity and the slider of the ladder resistance 21 moves in a direction a h, the uninverted input terminal of a comparator 11 which is held at the potential of a terminal (q) is pulled down to the lower-limit potential terminal 14 of the resistance 21 by a resistance 53 which has a larger resistance value than the resistance 21. Consequently, even if the slider 16 causes chattering or floats between terminals, the potential is pulled down to a lower limit potential and the output of the comparator 11 is not inverted. When the photographic lens moves in a direction infinity  N, a switch 18 is switched to a side p-m to connect the resistance 53 to the upper-limit potential terminal 13 of the resistance 21, so that an error in decision making by the comparator 11 due to the chattering of the slider 16 and its floating between the terminals of the resistance 21 are prevented.
