Title: Device for reduction converting rotation into linear motion
Inventor: BAN ITSUKI
IPC: H02K7/06
Filed: 1991-05-27
Abstract: PURPOSE:To reduce step width of load by constituting a reduction converter of a spiral rod having spiral teeth, a motor for rotary driving the spiral rod, and a load driven through a long rod. CONSTITUTION:When a spiral rod 4 is rotated by a motor A to rotate a spiral rod 5 in the opposite direction through gears 2, 3, a gear 6 meshed with the spiral rods 4, 5 moves, together with a long supporting rod 7, in parallel with the spiral rods 4, 5. Rotary shaft 6a in the center of the gear 6 moves together with a load B linked with the long rod 7. The spiral rods 4, 5 have same diamerters and the spiral teeth thereof have also same pitch S. Assuming the number of teeth of the gears 2, 3 are N-1 and N, respectively, upper teeth of the gear 6 move by a distance S to the right for single revolution of the motor A whereas the lower teeth move by a distance S(N-1)/N or (1-1/N)S to the left. Consequently, the long rod 7 moves by a distance S/N to the right. According to the invention, accuracy of the movement of load can be enhanced through a simple mechanism.

Title: Functional property inspection method of tank vent device in vehicle
Inventor: FRITZ THORSTEN
IPC: F02D41/00
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To detect the oversight of error diagnosis on the basis of inappropriate use by deciding and memorizing a tank liquid level at the time of start and completion of a stop, generating a difference between liquid levels, and outputting an error message only when the difference does not exceed a predetermined threshold value. SOLUTION: It is specified by measuring current supplied to a pump motor whether flow supplied from a pressure source 50 is different from supplying flow which exists when excessive pressure is supplied through a reference leakage 81 or not. When an engine is stopped, the liquid level in a tank is measured and memorized. And the other of the liquid level in the tank is measured and memorized, and a difference between the measured liquid level and a memorized liquid level is decided. It is decided whether the difference exceeds a predetermined threshold value or not. In the case where the difference is not larger than the threshold value, the existence of leakage is presumed, and an error message is outputted. It is thus possible to detect error diagnosis oversight due to inappropriate use.

Filed: 1990-08-28
Abstract: PURPOSE:To produce a laminated material of copper foil in which the coating thickness of soft solder is uniformized and the growth of an intermetallic compound of tin and copper is minimized by allowing molten solder to flow continuously onto a moving copper foil and subjecting the above molten solder to rapid cooling. CONSTITUTION:In a box 1 evacuated by means of a pressure reducing device 2 and containing a nonoxidizing atmosphere, a tape-shaped copper foil 3 is allowed to travel in the direction of arrow A. This copper foil 3 is cleaned by removing an oxide film from the surface by means of an oxide film removing device 8. Then, molten solder is allowed to flow onto the surface of the copper foil 3 through a nozzle 10 connected to the bottom of a molten solder tank 9. The molten solder flowing out through this nozzle 10 is cooled rapidly from the rear of the traveling copper foil 3 by means of a cooling drum 7. Because the molten solder flowing onto the copper foil is metallically joined to the copper foil 3 and also the length of time when the solder exists in molten state on the copper foil 3 is extremely short, the growth of the intermetallic compound of copper and tin in the soft solder can prevented. Further, the soft solder practically be adhering to the copper foil 3 surface is spread thin and regulated to uniform thickness.
