IPC: G01C17/30
Filed: 1981-08-21
Abstract: PURPOSE:To make it possible to detect the accurate azimuth at all times, by providing a demagnetizing coil in the vicinity of a geomagnetism sensor, and providing a power source device which supplies AC to said coil. CONSTITUTION:The azimuth detecting device comprises the geomagnetism sensor 1, the loop shaped demagnetizing coil 2 which is arranged around the sensor 1, and the power source device 3 which supplied the AC to said coil. The sensor 1 and the coil 2 are mounted, e.g. in the inside of the roof of a body. When an automobile passes a railroad crossing and the like, a power source switch 33 of an operating part B is turned ON. At the same time, the AC, which is supplied to the demagnetizing coil 2 through a battery 30 in a power supply part A, a DC-AC converter 31, and attenuator 32, s slowly decreased from the maximum value by an adjusting dial, and the magnetized magnetic field of the body is demagnetized. Therefore the geomagnetic sensor senses the geomagnetism without the effect of disturbance, and the accurate azimuth detection is performed.

Filed: 1994-05-20
Abstract: PURPOSE:To reduce the installation space of a discharge conveyor by dropping vessels in order from the push-out level on the uppermost step of a pallet onto the discharge conveyor of the lower part through a vertical discharge passage. CONSTITUTION:Vessels 1 of the uppermost step is elevated up to a specific push-out level by an elevator mechanism 4 through a control mechanism.

Next one line of vessels 1 are pressingly transferred again by a push-out mechanism 6. Each shutter 16-18 is opened/closed in cooperation with push-out operation of the push-out mechanism 6 under the condition in which the succeeding vessels exist on the over part and the preceding vessels do not exist the under space. Hence, the vessels on the uppermost step can be in order discharged one line by one line onto a discharge conveyor 24.

Title: Reddish water preventing device
Inventor: FURUHATA SATOSHI
IPC: C02F1/70
Filed: 1994-06-14
Abstract: PURPOSE:To effectively prevent the generation of reddish water even if a ball- shaped semiconductor catalytic material having a relatively small surface area- to-volume ratio is used in a reddish water preventing device for reducing rust with the semiconductor catalytic material by enhancing the contact degree between the semiconductor surface and water with respect to time and space. CONSTITUTION:City water is struck against the blade of a driving impeller 20 facing an inlet 13 to rotate the impeller 20, hence a shaft 19 is rotated, and agitating blades 21 and 22 are rotated. Consequently, the water passing through a chamber 17 is agitated, and the semiconductor catalytic materials 1 dipped in the water are agitated, suspended and revolved. Accordingly, city water is brought into contact with the catalytic members 1 widely for a long time while the water flows down to an outlet 14, hence the reducing action is remarkably activated, and the generation of rust is effectively suppressed.
