Title: Exposure adjusting device of solid-state image pickup device
Inventor: ARAKI AKISHI
IPC: H04N5/378
Filed: 1990-11-28
Abstract: PURPOSE:To allow the execution of a smooth and adequate exposure adjustment even if a shutter speed is extremely high by generating saw tooth waves of a large gradient just before the next reset pulse is supplied right after a reset pulse is supplied. CONSTITUTION:A shutter speed control circuit 20 has a saw tooth wave generating circuit 30. The saw tooth waves which increase an output potential at every time when a connecting switch 33 attains a connected state (i.e., every one field) and restore the original potential instantaneously when the specified potential is attained are obtd. from the saw tooth wave generating circuit 30. The output current value of a constant current source 31 of a vertical blanking signal V BLK is increased from the other period in this case and, therefore, the gradient at which the potential changes steepens. The saw tooth waves compared with a shutter control voltage in a high-speed shutter region are more steeply graded in the increase rate of the potential than the saw tooth waves compared in a low-speed shutter region and, therefore, the brightness of the subject is detected with a high resolving power in the high-speed shutter region and the control of the shutter speed with the high accuracy is executed.

Title: Coupling for connecting resin tube
Inventor: UMEZAWA KATSUSHI
IPC: F16L33/22
Filed: 1993-12-01
Abstract: PURPOSE:To sufficiently develop the function of an insertion member and permit the insertion of a tube having a small diameter in a reasonable manner by forming a large diameter part which is nearly equal or slightly larger than the inside diameter of a tube, at a part of the outer periphery of an insertion part corresponding to the hook wall part on the holding member side of the insertion member. CONSTITUTION:When an insertion member 3 is inserted inside the top end of a tube T or the top end of the tube T is externally fitted with the insertion member 3 which is inserted in a coupling body 1, the deflection deformation to the tube T side in the vicinity of the biting-in part of the hook wall part of a holding contact member 2 is effectively prevented by the insertion in a local contact state to the inner peripheral surface of the tube T side by a large diameter part 3' which is nearly equal or slightly larger than the nominal dimension of the inside diameter of the tube T of the insertion member 3. Accordingly, the holding force of the holding member 2 is sufficiently developed, and the trouble of the generation of leak even under an oscillation state is prevented. Further, even in the case of a tube having a small diameter, the insertion into the insertion member 3 in a reasonable manner is enabled by spreading the diameter on the tube side, accompanied with the local contact with the large diameter part 3'.

Title: Method of purifying contaminated air on highway
Inventor: NONOYAMA NOBORU
IPC: E01F8/02
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To purify contaminated air on a highway without occupying much space and impairing a fine view. SOLUTION: When a solar battery panel 10 is irradiated with sunlight, a fan 8 is driven by electric power generated by the solar battery panel 10 to suck the contaminated air on the highway 2 through first, second air sucking ports 22, 24, and the contaminated air flows downwards while it expands right and left by a wind guiding plate 2006 along a surface layer 6 of a sound arresting wall 4 from an air blowing port 20. On the other hand, on the surface layer 6, titanium dioxide receives sunlight to cause photocatalytic reaction. Therefore, among contaminants in contaminated air blown out from the air blowing port 20, for example, nitrogen oxide is finally converted into nitric acid by photocatalytic reaction and is held on the surface layer 6 as nitric acid. The contaminant such as nitric acid held on the surface layer 6 is washed away by rainwater during rain and is removed.
