Title: Position detecting system
Inventor: TUHRO RICHARD H
IPC: G03G21/14
Filed: 2000-08-22
Abstract: PROBLEM TO BE SOLVED: To reduce variation of image formation light with Z-direction position change by determining a position of a support body based on an electric signal generated from the image formation light on an image plane, and providing a telecentric diaphragm between a lens and an optical sensor system. SOLUTION: A light emitting diode 154 radiates light to an optical sensor array 156, and the light transmitting through a support body 162 is imaged on the optical sensor array 156 by a lens 158. An optical assembly 157 comprises a telecentric diaphragm 160. An electric signal from the optical sensor array 156 is supplied to a position determining network 161. The support body 162 progresses in an arrow 164 direction through an LED 154 and the lens 158. The support body 162 is apparently disposed on an objective plane of the lens 158, and the telecentric diaphragm 160 reduces an effect based on the variation in the Z-direction of the position of the support body.  The position determining network 161, when the support body 162 progresses in the arrow 164 direction, senses reduction of light quantity, determines that it comes to a sensing region, and can accurately track the progression of the support body 162.

Title: Rainwater intake joint
Inventor: IMAMURA HIROSHI
IPC: E04D13/08
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a rainwater intake joint which reduces its tendency to be clogged with dust, and facilitates cleaning thereof even if it is clogged with dust. SOLUTION: Dust contained in rainwater flowing from an upper down pipe to an opening 4 at an upper edge of an external cylinder of the rainwater intake joint 1, is removed by a filter member 11, and therefore it does not fall into a rainwater reservoir 8. Further, the filter member 11 is formed like a funnel, so that the dust is not deposited on the filter member 11 but discharged from the interior of an internal cylinder 3 via a lower down pipe to the outside. Therefore, only rainwater containing no dust is stored in the rainwater reservoir 8, and then stored via an intake pipe 9 into a rainwater tank. The rainwater intake joint is arranged at a location between the upper down pipe and the lower down pipe by forming a gap therebetween, which facilitates detachment thereof from the down pipes.  Therefore, the interior of the intake joint can be easily inspected, and the joint per se can be easily detached, which facilitates cleaning of the joint main body, whereby routine maintenance thereof becomes convenient.
