Title: Electrophotographic photoreceptor and image forming apparatus equipped with the same
Inventor: FUKUSHIMA KOUTARO
IPC: G03G5/04
Filed: 2003-06-20
Abstract: <P>PROBLEM TO BE SOLVED: To obtain an excellent wear-resistant life and to prevent flaws or density irregularity in a formed image for a long period of time by specifying the physical properties of the surface of an electrophotographic photoreceptor to be subjected to non-contact electrifying processes.  <P>SOLUTION: The electrophotographic photoreceptor to be subjected to a non-contact electrification process has ≥2.70%, preferably ≥3.00%, creep C<SB>IT</SB>, and ≥220 N/mm<SP>2</SP>and ≤275 N/mm<SP>2</SP>plastic deformation hardness (Hplast) of the surface when the surface is loaded with indent force of 30 mN maximum in the environment at 25°C and 50% relative humidity. Because the electrophotographic photoreceptor 1 having such characteristics has excellent flexibility but is not too soft and has plasticity without showing no brittleness, the photoreceptor causes little reduction in the film thickness by wear for long-term use. Further, the photoreceptor has excellent surface smoothness and induces no flaw or density irregularity in a formed image.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: G03F1/84
Filed: 2003-06-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of inspecting and cleaning a mask, which efficiently detects and removes foreign matters adhering on a reticle.  <P>SOLUTION: A mask inspecting and cleaning apparatus 50 is provided with a light source 51 that irradiates a reticle 21 with a pulsed laser light, and a means 53 for adjusting the light intensity of the pulsed laser light. In inspecting the reticle 21, the reticle 21 is irradiated with a pulsed laser light whose intensity is reduced by a light-quantity adjustment mechanism 53, and the transmitted light or the reflected light is detected and analyzed to detect adhesion of foreign matters. In cleaning, the reticle 21 is irradiated with a relatively strong pulsed laser light from the light source 51 to remove foreign matters from the reticle surface. Thereby, the inspection and cleaning of the reticle are carried out with a sequence of works, and the working time is shortened.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Motor driving device
Inventor: SAKAMOTO KEIJI
IPC: G01R31/34
Filed: 2003-06-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a motor driving device for inexpensively predicting the insulation deterioration of a motor.  <P>SOLUTION: This motor driving device is structured so that a closed circuit is formed by turning on a relay contact K1 while a motor drive amplifier 8 is off, the closed circuit comprising a grounded G2 housing of the motor 10, a motor coil, a resistance R1, a resistance R2, a relay contact K1, diodes D4, D5 and D6, an AC power supply 1, and ground G1. This causes a voltage-to-ground of the power supply 1 to be impressed on the closed circuit. When the insulation resistance of the motor 10 is high, a current flowing through the closed circuit is small to cause a potential difference across the resistance R1 to be small. When the insulation of the motor is deteriorated, leak current increases. When potential difference of the resistance R1 exceeds a reference voltage determined by a zener diode, an output signal is outputted from a comparator 32 and a signal is outputted from a photo-coupler 35, causing an indicator of a controller 11 to display insulation resistance deterioration. This makes it possible to simply and inexpensively predict insulation deterioration of the motor to prevent electric leakage, etc. from causing sudden operation stoppage.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
