Title: Floor cleaning device for unmanned carriage
Inventor: SATO MAKOTO
IPC: E01H1/14
Filed: 1989-09-21
Abstract: PURPOSE:To enable the removal of a large quantity of chips attracted with a cleaning device via a simple operation and in a short time by providing the front and rear bumpers of an unmanned carriage with a magnet storage case of non-magnetic material, and a magnet so housed in the case as to be slidable in a vertical direction. CONSTITUTION:A floor cleaning device 10 is so mounted to the safety bumpers of an unmanned carriage 1 as to form a pertinent gap between the underside of the device 10 and a floor surface. In addition, the carriage 1 is made to travel in the condition where a magnet 12 housed in a magnet storage case 11 is lowered. Then, chips 17 scattered on the floor surface of a travel route are attracted to the lower half and bottom of the outside of the case 12 with a magnetic force generated by the magnet 12. When a large quantity of the chips 17 is attracted to such an extent as incapable of further attraction, the unmanned carriage 1 is stopped, the support 16b of the magnet 12 is moved up by hands and the magnet 12 is lifted, while being made to slide within the case 13, thereby eliminating the magnetic force and causing the natural fall of the chips 17.

Title: Drive circuit for transistor
Inventor: KATO YOSHIRO
IPC: H02P7/29
Filed: 1988-09-28
Abstract: PURPOSE:To simplify circuit constitution, and to miniaturize the whole circuit by directly driving a transistor by a pulse transformer and obtaining the continuous ON state of the transistor. CONSTITUTION:In a circuit driving a transistor 1 insulated from a main power supply, a pulse signal (an ON signal) having a fixed period input to the transistor 1 is insulated by a pulse transformer 31, and the period and duty of the signal are set properly, thus continuously turning the transistor 1 ON. Since there is surely the storage time until the transistor 1 is turned OFF actually after the ON signal is interrupted in the transistor 1, the time when the base input of the transistor 1 is cut off may be brought to the time less than the storage time. Accordingly, a power circuit and a photo-coupler need not be used completely, thus simplifying and miniaturizing the whole circuit.
