Title: Displacement/speed measuring instrument
Inventor: TAMAMURA HISASHI
IPC: G01B11/00
Filed: 1994-09-30
Abstract: PURPOSE: To easily measure the displacement and speed of an object to be measured with high accuracy by offsetting errors caused when a polarizing plane maintaining optical fiber is given bending, impact, or vibration, by simultaneously transmitting measuring light rays and reference light rays through the optical fiber. CONSTITUTION: First and second laser beams having different angles of polarizing planes and frequencies are propagated through a polarizing plane-maintaining optical fiber 12 while maintaining the relation between the polarizing planes after being emitted from a light source 10, and separated from each other through a beam splitter 36 in a measuring head 14, and the first laser beam is projected on an object 15 to be measured. The second laser beam is reflected by a reference reflection mirror 38, reversely propagated through the optical fiber 12 together with reflected light from the object 15, and transmitted to a measuring means 16 after being reflected by a half mirror 26. The measuring means 16 only transduces the component which is polarized in a prescribed direction through a polarizing filter 40 into electric signals.  The electric signals are processed 44 by an optical heterodyne method and the speed and displacement of the object 15 are measured.

Title: Image forming device
Inventor: SAITO HIROSHI
IPC: G03G15/08
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device where image forming with excessive density and surface staining are surely reduced. SOLUTION: A CPU firstly executes developer stirring processing for 30 seconds (substep sb1-2) after starting the rotation of a photoreceptive drum (substep sb1-1). The triboelecltricfication of two-component developer is accelerated by the developer stirring processing, so that the surface staining at the non- image part of the photoreceptive drum is reduced. Next, after a P-pattern is formed at a specified position on the photoreceptive drum by the CPU (substep sb1-3), the toner stuck amount measured value (hereinafter referred to as Vsp) of the P-pattern is referred to (substep sb1-4). Then, in the case of judging as Vsp<0.39 (yes at substep sb1-4), it is judged that the surface staining of a quantity exceeding a tolerance is caused on the photoreceptive drum, so that the sequence of control is looped with the substep sb1-2 so as to stir the two-component developer at the inside of a developing device more. Looping is executed until the CPU judges as Vsp>=0.39 at the substep sb1-4.
