Title: Detector for mass spectrograph
Inventor: YAMAZAKI HIROMI
IPC: H01J49/38
Filed: 1991-05-10
Abstract: PURPOSE:To enhance maintenability and accuracy in detection as well as to relax the requirements for a specified installation space by employing the flange connection connecting a detector main body to a cover body, which is oblique to the direction that a permanent magnet is inserted into magnetic poles. CONSTITUTION:A detector 1 for a mass spectrograph is made up of a closed-end rectangular parallelopiped detector main body 3 the upper section of which is opened while being furnished with a wiring system 2 to a measuring cell 33, and of a cover body 4 covering the open section of the main body 3. And the main body 3 is connected to the cover body 4 by means of the junction between high vacuum type flanges 3a and 4a which forms a slant to the insertion direction for both the magnetic poles 31 and 32 of a permanent magnet within a constant temperature oven 30. By this constitution, the maintenance and inspection of the cell 33 and the wiring system can be easily performed only with the cover body 4 removed from the main body 3, and accuracy in detection can concurrently be enhanced because the cell 33 can be disposed close to the wiring system. In addition, it is not necessary that a detector/ pump mechanism has to be pulled out of the magnet excessively, maintenance operations can be simplified with the installation space made small, and furthermore, sensitivity can be prevented from being lowered.

Title: Treatment of scrap preheating waste gas
Inventor: SATO TAKERO
IPC: F27D17/00
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To reduce oil in waste gas carried in a dust collector to prevent the occurrence of trouble by cooling scrap preheating waste gas to prescribed temperature or less by an indirect heat exchanger and condensing and sticking oil in waste gas to dust contained in scrap dissolving furnace formed gas. SOLUTION: In a preheater 2, air is blown into scrap dissolving furnace 1 formed gas to burn it, allowing scrap to be heated. The generated waste gas is cooled to 100 deg.C or less by an indirect heat exchanger 3 to condense and stick oil contained in the waste gas to dust in the waste gas, and the dust is collected by a preduster 4 consisting of a cyclone. After that, the waste gas is further filtered to collect the dust by a filter type dust collector 6 and is discharged as clean gas. Since the condensation effect of oil to dust is thus utilized without resorting to a combustion means on scrap preheating waste gas treatment, the treatment is made easily and with high effect, and a fear of fire or the like is wiped away.

Title: Optical system for scanning plural beams
Inventor: TATSUOKA MASAMICHI
IPC: G02B27/10
Filed: 1985-05-17
Abstract: PURPOSE:To take in light sufficiently from a light source part without expanding the size of an optical system by arranging an optical member for separating a beam spot based upon optical beams radiated from the 1st and 2nd optical sources on a photodetecting surface slightly in the direction rectangular to a scanning direction between one light source part and an optical coupler. CONSTITUTION:When semiconductor lasers 1a, 1b are arranged so as to polarize light in the arrow directions 16, 17 respectively, light projected from the semiconductor 1a is turned to a P component by a polarized beam splitter 9 (P is transmission and S is reflection) and almost 100% light is transmitted. Although light radiated from the semi-conductor laser 1b is polarized in the arrow 17 direction at first, the polarizing direction of the light is rotated by 90 deg. by a 1/2 waveform plate 7 and the light polarized in the arrow 18 polarizing direction is made incident on the polarized beam splitter 9. Since the incident light is an S component, almost 100% light is reflected. Consequently, the light from the light source part can be sufficiently taken in by using a half mirror or the like.

Abstract: PROBLEM TO BE SOLVED: To make an equipment small in size and thin in thickness by inserting a semiconductor equivalent circuit to subscriber lines at a reference point and a U point with respect to an ISDN(integrated services digital network) line. SOLUTION: It is necessary to efficiently send a high frequency signal to a DSU(digital service unit) 12 through a high frequency transformer. At a U point, it is necessary that a DC component is cut by setting a signal component to a high impedance to allow only a high frequency signal component to pass through and that lines L1 and L2 are short-circuited for a test loop 2A from an exchange at the time of originating a call from a terminal. In this case, the resistance value is set to <=Ω812. A semiconductor equivalent L circuit 17 is inserted instead of a conventional RL filter, and then, heat generation is suppressed, and the equipment is made small-sized and thin, and further, a high filter effect is obtained.

Filed: 1984-05-26
Abstract: PURPOSE:To solve various problems occuring in a casting method by producing an inside cylinder consisting of a copper alloy having a cooling wall made into a grooved construction to the outside circumferential wall by a powder metallurgical method using the copper-base alloy which is produced by an atomizing method and has heat resistance and high heat conductivity. CONSTITUTION:The copper alloy powder of Cu-Ag, Cu-Zr, etc. can be produced by a melting-inert gas atomizing method. The grain size of the powder is preferably about <=100 mesh. Such powder is generally spherical and has therefore the advantage that the packing density can be increased. The inside cylinder 1 having the cooling wall pvorided with cooling grooves 2 is produced by the powder metallurgical method using the powder which consists essentially of copper and is formed by incroprating oxide such as, for example, Y2O3 or ZrO to the above-mentioned powder. The problems such as the segregation in the solidifying stage by a casting method, the generation of the defective pouring characteristic of a liquid metal, the generation of ingot defects such as shrinkage cavity or holes, the nonuniformity of the alloy phase owing to the gravity field and the laboriousness and high cost of working the grooves 2 are solved with such cylinder 1.

Title: Phased array radar equipment
Inventor: OKUGAWA HARUKI
IPC: H01Q3/30
Filed: 1983-06-15
Abstract: PURPOSE:To perform stable operation without losing a target by keeping the tracking error of a radar system and tracking characteristics such as a tracking distance, by correcting the change portion of the antenna characteristics corresponding to a beam scanning angle. CONSTITUTION:In a beam scanning angle other than a front direction, angle error sensitivity characteristics changes to result in a primary factor for increasing a tracking error. Therefore, the correction of an error angle signal is performed by an error angle correcting circuit 9 and a real error angle signal is supplied to a beam control calculator 5 through an error angle detecting circuit 8. The error angle correcting circuit selects correction constant at every beam angle scanning to output the error angle signal while corrects the same. In addition, the tracking distance R of a radar system depends on S/N of the transmitting receiving gain receiver of an antenna to compensate the lowering portion of the antenna gain due to a beam scanning angle and, because the characteristics of the radar system are always kept constant, a control signal corresponding to the lowering portion of the antenna gain of the beam scanning angle is sent to a transmitter 2 from the error angle correcting circuit 9. In this case, S/N is improved by controlling a pulse transmitting time to maintain system characteristics.
