Title: Method and device for detecting mark distribution pattern, and image forming device
Inventor: HOSOKAWA JUN
IPC: H04N1/29
Filed: 2000-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a mark distribution pattern detecting method for reading several marks in array by relatively scanning by optical sensors, performing an A/D conversion of a read signal at a prescribed pitch, specifying a scanning position and storing it in a memory and forming the distribution information on each mark based on the scanning position on the memory, as for a data group whose scanning position is adjacent to each other and which belongs to a specified read signal changing area. SOLUTION: Mark arrays Akr,.../Akf,... are read by relatively scanning (y) by the sensors 20r/20f, and the A/D conversion of the read signal is performed at the prescribed pitch Tsp, and only the conversion data of the read signal in intermediate areas 2-3 V is stored in the memory after specifying the scanning position Nos. The positions of the leading end edges (a) and (c) of the mark are calculated based on the scanning positions of the data groups having the adjacent scanning positions and belonging to the area of changing from 5 V (absence of mark) to 0 V (presence of mark) on the memory, and then, the positions of the trailing end edges (b) and (d) are calculated based on the scanning position of the data group belonging to the area of changing from the subsequent 0 V to 5 V, then, the mean value of both edge positions is calculated as the center point position of the mark.

Title: Displacement sensor
Inventor: MOMOSE SHOGO
IPC: G01B7/00
Filed: 2000-12-07
Abstract: PROBLEM TO BE SOLVED: To obtain a stable detection result while obtaining a good detection sensitivity in a simple constitution. SOLUTION: Exciting coils 13c, 13d are disposed separately from a detecting coil 12 for detecting the displacement, based on the balance between the pair of exciting coils 13c, 13d. This cancels impedances ascribed to d-c resistances thereof, etc., and a compact core 11 is used to obtain a change quantity remaining after this cancel at a high sensitivity with a satisfactory linearity. Thus a low-cost circuit allows the stable detecting operation, irrespective of the ambient temperature change, without using any constant-current circuit as in the prior art.

Abstract: A primary metal-air power source containing one or more metal-air cells incorporating an air manager in a power source housing of the power source. The power source provides intermittent use at high power levels over a long lifetime while demonstrating a high utilization of the metal, such as zinc, making up the metal-air cell's metal anode. The power source provides 80% of its amp hour capacity for at least 30 days after the initial partial discharge at a power level of at least 50 milliwatts. The cumulative run time may comprise any number of intermittent connections to a load having varying duration. The ventilation system of the power source draws ambient airflow through an isolating passageway by operating an air mover which distributes the airflow to the metal-air cells. A portion of the airflow is recirculated by the air mover and returned to the metal-air cells and the remaining portion of the airflow is moved through a second isolating passageway to the exterior of the power source's power source housing. The movement of airflow into and out of the power source is minimized during in-service storage.

Abstract: A precision, micro-mechanical semiconductor accelerometer of the differential-capacitor type comprises a pair of etched opposing cover layers fusion bonded to opposite sides of an etched proofmass layer to form a hermetically sealed assembly. The cover layers are formed from commercially available, Silicon-On-Insulator ("SOI") wafers to significantly reduce cost and complexity of fabrication and assembly. The functional semiconductor parts of the accelerometer are dry-etched using the BOSCH method of reactive ion etching ("RIE") thereby significantly reducing contamination inherent in prior art wet-etching processes, and resulting in features advantageously bounded by substantially vertical sidewalls.
