Title: Method for processing signal of underground probe
Inventor: KANEMITSU YASUO
IPC: G01V3/12
Filed: 1994-11-08
Abstract: PURPOSE:To enable only echos from foreign matter to be detected by comparing received signals with each other which are obtained from different positions at different probing distances along the same forward direction of an underground probe, and eliminating signals that are invariable with respect to the different positions along the forward direction of the probe. CONSTITUTION:Images produced by noise signals temporarily and discretely appear at almost the same position on a B-scope screen irrespective of the movement of an excavator, so echos from foreign matter can be distinguished from the noise signals by comparison of received signals obtained at different positions along the forward direction of the excavator. Pulse-like electromagnetic waves 30 generated by a transceiver 28 are radiated into the ground from a transmitting antenna 24. A receiving antenna 26 captures waves 34 reflected by any underground foreign matter 32 and sends them to the transceiver 28. The transceiver 28 is connected to a signal processor 38 via a rotary connector 36 and sends signals from the receiving antenna 26 to the signal processor 38. A display device 40 for displaying the underground condition in front of the excavator 20 and a warning portion 42 that sounds an alarm if any foreign matter 32 is detected are connected to the respective portions of the signal processor 38.

Title: Process cartridge and electrophotographic image forming device
Inventor: MIYAMOTO JUN
IPC: G03G15/08
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To surely hold waste toner in a toner storing part by making the tilt direction of the gigging of a 1st seal member a forward direction with respect to the rotating direction of a toner image carrier and that of a 2nd seal member a reverse direction thereto. SOLUTION: An end seal member 71 is a gigged member similarly to a cleaning seal member 74 and is inclined to a more downstream side than perpendicular to the rotating direction of a photoreceptor drum. Namely, the tilt direction of the gigging of the member 74 is the reverse direction to the rotating direction of the photoreceptor drum and that of the member 71 is the forward direction with respect to the rotating direction of the photoreceptor drum. When the photoreceptor drum is rotated, the toner adhering to the photoreceptor drum passes through the member 71 whose gigging tilt direction is the forward direction, and is scraped by the member 74 whose gigging tilt direction is the reverse direction, and scraped down into a slit. Since the gigging tilt directions of the members 74 and 71 are set to be tilted toward the slit, the toner is surely held.
