Abstract: PURPOSE:To improve the corrosion resistance and the joining strength of a junction part by executing a junction in a state that a shape of the junction part is inclined at the time of bringing different kinds of metallic members to solid phase joining. CONSTITUTION:At the time of joining a member 1 consisting of a Zr compound stock, etc., and a member 2 of a stainless steel stock, etc., a male die tapered part 3 is formed in the tip of the member 1, and a female die tapered part 4 is formed in a joining position of the member 2.

IPC: G03G15/04
Filed: 1992-07-10
Abstract: PURPOSE:To make it possible to perform an optimum optical magnification drive by applying a proper voltage through the use of a voltage change-over portion for switching a voltage applied to a stepping motor and of a control portion for outputting signals which switch the voltage applied to a higher one in zoom mode and to a lower one in fixed magnification mode. CONSTITUTION:An armature 51a of a relay 51 is connected in parallel with a constant voltage diode ZD for self-bias, a coil 51b of the relay 51 is connected between a controller 50 and a power supply E1 thereby constituting a voltage change-over portion S with this relay 51. The relay 51 of this voltage change- over portion S is turned on/off by the command from the controller 50 for switching the voltage applied to a stepping motor 40. During zoom mode, the start, stop and reverse rotation of the stepping motor 40 are performed intermittently, so that the load torque increases and the margin of self-start region is reduced. Because of this, the voltage change-over portion S operates and the voltage applied is increased to secure a required torque. The voltage applied is lowered during the fixed magnification mode.

IPC: G02B26/10
Filed: 1991-08-20
Abstract: PURPOSE:To reduce the manufacture cost, to improve the reliability, and to simplify the constitution circuit of an electronic controller which controls the optical control element of a spatial optical modulator. CONSTITUTION:An image based upon a video signal is formed, line by line, on a screen 3 by a linear optical modulator 2 which is formed by arraying plural optical control elements 1 linearly and an optical scanning device 4 which deflects the linearly modulated light from the linear optical modulator 2 to scan the screen 3 in the direction perpendicular to the longitudinal direction of the linear optical modulator 2. The scanning time of one scan is made shorter than one cycle of the critical flicker frequency of the human to recognize a difference in the quantity of light on the screen due to a difference in operation time of each optical control element 1 as a difference in brightness of each picture element with the human eye. Thus, the purpose is attained by using the linear optical modulator 2 which is much less in the number of optical control elements than a two-dimensional optical modulator.

Title: Sealing of tubular bulb
Inventor: TANIOKA MASAHIRO
IPC: H01J9/26
Filed: 1981-12-22
Abstract: PURPOSE:To prevent any generation of cracks which might be caused in the following process by fusing together the end part of a tubular bulb, and the flare part of a stem which is provided with a coil, slightly moving back a burner, and removing the distortion of the flare part by making flame to reach to the base part of the stem through a space formed between the flare part and the end of the burner. CONSTITUTION:An exhaust tube 7 of a stem 2 is supported with an exhaust device 4. While the periphery of a flare 16 is preheated by flame discharged from a burner nozzle 15, the exhaust device 4 is sleeved along a supporting shaft 21 and moved toward the end of a tubular bulb 1. When the flare 16 touches the end of the tubular bulb 1 and further moves ahead, a supporting plate 8 becomes apart from a stage part 19 of the tubular convex part of the exhaust device 4, and comes to be pressed by a spring 12. After that, the movement of the device 4 is stopped, and main baking is performed. Next, the plate 8 supporting a burner 3 is moved to the right in the figure, against the spring 12, by means of a cum 11. As a result, only the burner 3 moves, and the end 17 of the burner 3 stops at a point 2-3mm. apart from the flare 16. At this point, the flame of the burner 3 reaches through the above space between the flare 16 and the end 17 to the base part of the flare 16, so that the distortion of the flare 16 is removed.

Abstract: PURPOSE:To extract automatically a sample vessel which indicates an abnormal result of measurement and to make measurement again after diluting the same by housing the sample vessel in a circulation type sample vessel imposing means. CONSTITUTION:A control circuit 23 sucks the sample of a specified volume V0 and specified volume of pure water successively from the sample vessels B of a turn table 3, dispenses the same into reaction tubes 18, and transfers the tubes 18 to a reagent injecting mechanism 19 and an absorptivity detector 20. On the other hand, the table 3 is driven and a circuit 15 for selecting the amt. of the sample to be sucked is operated simultaneously to select either of the suction volume V1 or V2 for reinspection when a reinspection command signal is outputted from a circuit 22 for monitoring the result of the measurement. The circuit 23 inserts a sample suction nozzle 6 into the vessel requiring the reinspection and drives a pulse motor 12. The sample of the volume V1 to be reinspected is thereby dispensed into the tube 18, then the specified volume of the pure water is injected therein. The volumes of the pure water and reaction reagent at the time of the reinspection are the same as at the time the ordinary inspection; therefore, a reagent blank value fluctuates. A measurement value correcting circuit 21, therefore, corrects the output from the detector 20.
