Title: Antenna system
Inventor: HIROSE MASANOBU
IPC: H01Q1/38
Filed: 1993-06-30
Abstract: PURPOSE:To make an antenna system high-gain and wide-band by constituting this system of an inverted-F type antenna and a quarter-wave micro strip parastic element having the same resonance frequency as this antenna system and making the open end of the parastic element parallel with and close to one side of the inverted-F type antenna. CONSTITUTION:A quarter-wave micro strip parastic element 3 is set on a side face 2a of a metallic enclosure 2 of an inverted-F type antenna 1. The resonance frequency of the parastic element 3 is slightly shifted from that of the inverted-F type antenna 1, and an open end 3C is at right angles to the side, to which a feed point member 1b is connected, out of four sides of a radiation element 1d like a plate and is parallel with and close to a side, and the distance between them is shorter in comparison with the resonance frequency. The opposite side of the open end 3C is formed together with a plate-shaped part 3a as one body and is connected and fixed to a side face 2a by a short flange part 3b to become a short-circuit end. Double resonance is brought about by the interaction of both of them to not only realize a wide band but also improve the gain.

Abstract: PURPOSE: To extremely lower the nitrogen content of the chromium-containing metal or alloy to produce an extremely low-nitrogen product by heating metallic chromium, ferrochromium or the like to a specified temperature together with alkali metal and/or alkaline earth metal and halide thereof as a flux.  
     CONSTITUTION: A powder of metallic chromium, ferrochromium or the like with a particle size of 10W200 mesh, together with one or more alkali metals and/or  alkaline earth metals and one or more halides thereof as the flux, is heated in an Ar gas atmosphere at 800W1,000°C for 30minW5hr and is then cooled in Ar gas or a gas having an extremely low nitrogen partial pressure to reduce the nitrogen content, thereby producing the extremely low-nitrogen product. In this case, not more than 2.0S tons of the chromium-containing material is placed in a reaction vessel having a horizontal cross-sectional area of not greater than 0.2m 2  and is treated in situ. As the flux, the alkali or alkaline earth metal such as Ca, Mg, etc. is used in an amount of not less than 5 times of that of the nitrogen to be removed, while the halide such as CaCl 2 , MgCl 2 , NaCl, etc. is used in an amount of 3W30% of the metal to be treated. After the treatment, water is added to remove the used flux from the powdery chromium-containing metal.

Title: Developing device for single color copying machine which permits color selection
Inventor: IMAI TSUTOMU
IPC: G03G15/01
Filed: 1985-08-29
Abstract: PURPOSE:To obtain a dark and good image density regardless of the kind of an original by changing over development time according to the image condition of the original and the kind of a developer. CONSTITUTION:The change-over of the development time is made possible according to the image condition of the original and the kind of the development. For example, electrostatic charging, erasing, exposing and developing are executed in the conventional manner in the 1st copying; thereafter, the rotation of a photosensitive drum 1 is continued while the transferring, separating, cleaning and destaticizing are not-operating. The drum 1 is subjected to the 2nd rotation in succession thereof and in this stage the charging, erasing and exposing are in the non-operating state but the developing, transferring, separating, cleaning and destaticizing are operated. Since the development is eventually executed twice during one copying process with the drum 1, the deposition of the developer increases and the developing power improves. As a result, the reproducibility of the solid image improves as well.

Abstract: PURPOSE:To obtain a stable positional shift signal without exerting no effect of the drift of the angle of deflection of a galvano mirror on the positional shift signal by obtaining the quantity of positional shift from the phase difference between the diffracted beam signal from a mask and that from a wafer. CONSTITUTION:A mask 1 and a wafer 2 are arranged so as to be spaced apart by a predetermined gap S from each other and a large number of linear diffraction lattices 3 are arranged on the mask 1 at a definite interval so that the longitudinal direction thereof crosses a positional shift detection direction A at a right angle.

When the diffracted beam signal from the linear diffraction lattice 3 on the mask 1 and that from the linear diffraction lattice 4 on the wafer 2 are separately detected, the phase difference between the AC components of the respective diffracted beam signals shows the relative positional shift of the mask 1 and the wafer 2.
