Title: Waveguide measuring instrument
Inventor: EKUMA SHUNJI
IPC: G01B15/00
Filed: 2001-02-14
Abstract: PROBLEM TO BE SOLVED: To provide an instrument and a method for waveguide measurement which precisely measure the circularity of the internal diameter of a waveguide. SOLUTION: A converter 10 is mounted on a turntable 2 and a coaxial- waveguide transducer 3 connected to a port 1 of a vector network analyzer is applied to the waveguide 7 to input an electromagnetic wave. One end of the waveguide 7 is closed with a reflecting material 5 made of metal, so the electromagnetic wave passes through an attachment 4 and the waveguide 7, is reflected by the reflecting plate 5, and then passes through the waveguide 7, attachment 4, and coaxial-waveguide transducer 3 again to return to the port 1 of the vector network analyzer. Consequently, phase characteristics of the S11 (reflection) mode of the vector network analyzer 9 are measured. Then the turntable 2 is rotated by 90 deg. so as to input an electromagnetic wave at right angles to the measured electric field direction and phase characteristics of reflection are similarly measured.

Title: Image forming device
Inventor: SHIMURA EIJI
IPC: G03G15/00
Filed: 2001-03-23
Abstract: PROBLEM TO BE SOLVED: To decrease the occurrences harshness images, restrict development of harshness of the image, and prevent the harshness from occurring in an early stage after toner replenishment. SOLUTION: One of discard patch formation set values a, b, and b' is set in an area where an amount of remaining toner is before and after the end that includes a set value end for toner replenishment. When the amount of toner remaining in a developing unit reaches one of discard patch formation set values a, b, and c', a discard patch is formed on a photoreceptor, and a specific amount of toner in the developing unit is consumed. Thus, the toner of a relatively large diameter, which has not hitherto been used for an image forming operation is consumed, so that the proportion of the large-diameter toner remaining in the developing unit after the formation of the discard patch decreases. Accordingly, the occurrences of harshness images caused by the large-diameter toner decreases and development of the harshness of the image is restricted.  Further the harshness of the image is prevented from occurring in the early stage.
