Title: Contamination evaluation device and contamination evaluation method using the same
Inventor: TAMARU HIROSHI
IPC: G01N27/06
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To quantitatively evaluate the contamination degree of an entire article to be evaluated for its contamination by detecting the potential difference between both ends of a flow-in route of an electrolyte being sent from one side of the flow-in route to the other side, and glowing contacting with a charged surface. SOLUTION: An inert gas is introduced to an electrolyte tank 11 by opening a gas cylinder and the liquid surface of the electrolyte 1 of the electrolyte tank 11 is pressed. The electrolyte 1 is sent through an electrolyte piping part 13 to a flow-in route 31, and made flat to be sent from one side of the flow-in part 31 to the other side along the charged surface 21 of an article 2 to be evaluated for contamination. Then, it is passed through the electrolyte piping part 13 of the other side and housed in an electrolyte tank 12. In this case, when the electrolyte 1 flows to the flow-in route 31, the potential difference of the electrolyte 1 between both sides of the flow-in route 31 is changed according to the electric charge holding amount of the charged surface 21, that is, the degree of contamination.  This potential difference is detected by a detection electrode 5, amplified by a potentiometer 6, calculated by a personal computer 8 and then the contamination degree of the article 2 to be contamination- evaluated is evaluated.

Title: Laser distance measuring equipment and travel control system for vehicle equipped with laser distance measuring equipment
Inventor: SHIMIZU KAZUHISA
IPC: B60R21/00
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To perform constant inter-vehicle distance follow-up traveling in safety even on an entering lane, e.g. an interchange of highway or an uphill lane, into which a vehicle enters at low speed. SOLUTION: The lane width detecting section 35 of a laser distance measuring equipment 21 detects a laser pulse L reflected on a road side reflector installed on a guide rail, or the like, thus detecting the lane width or the road width. An entering lane detecting section 36 detects an entering lane based on the variation of lane width or road width. A travel control section 22 enlarges the detecting region from its own lane to other lane when an entering lane is detected and monitors an entering vehicle. Subsequently, traveling speed of its own vehicle is controlled depending on the speed or inter-vehicle speed of the entering vehicle.

Title: Image forming device and process cartridge
Inventor: SATO HIROSHI
IPC: G03G21/16
Filed: 1995-01-09
Abstract: PURPOSE: To prevent a process cartridge, using a contact electrification member as a member for electrifying a photoreception drum, from causing unsatisfactory electrification due to deformation as a result of being left out of the device for a long period. CONSTITUTION: The electrifying roller 2 is pressurized to the photoreception drum 1 by means of a pressurizing member 13, and is so supported with a light-shield member 12 as to move upward and downward freely. The pressing member 11 of the main body rotates the light-shield member 12 around a rotation center 10 to open an opening 6a, thereby exposing the photoreception drum 1 to exposure light L1. When the process cartridge 7 is detached in the direction of the right of an arrow, the light-shield member 12 moves away from the pressing member 11, rotates counterclockwise around the rotation center 10 by means of a spring to close the opening 6a and also separates the electrifying roller 2 from the photoreception drum 1. This prevents deformation of the electrifying roller 2 and partial deterioration of the photoreception.

While because the low temperature part 4 is provided in the side of the magnet 3, when the mover 1 moves to the side of the magnet 3, the mover 1 is cooled till it is in a superconducting state. And the mover 1 is repulsed by a Meissner effect, moving to a side of the high temperature part 5. As a result, the mover 1 reciprocates between the low temperature part 4 and the high temperature part 5.
