Title: Dust removing device
Inventor: KAWACHI KAZUHIKO
IPC: H01L21/304
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To completely remove dust on a work without adjusting a stage, without exercising adverse influence on a destaticizer, and without scattering dust containing air to the surroundings. SOLUTION: In this device, two dust collectors 10A and 10B are formed connected to each other, and a valve 11 is installed in a line 7 on the pressure side of the dust collector 10B installed on the upstream side to the advancing direction of a glass substrate. When washing the glass substrate, without lowering the sucked quantity from a head part 2d on the upstream side, discharge force of air discharged from a head part 2c on the upstream side is set weaker than that of air discharged from a head part 2a on the downstream side by opening the valve 11. In this way, air leakage from a cleaning head 2 to the surroundings can be prevented.

Title: Defrosting method and defrosting device
Inventor: YAMAJI YASUHIRO
IPC: F25D21/06
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To permit preventive defrosting, reducing the front formation on a cooler, by a method wherein air, cooled by the cooler, is passed through the front formation medium of a mesh structure to adhere moisture, contained in the air, to the frost formation medium and, thereafter, the frost adhering medium is vibrated.

Moisture, contained in the air A and separated by the round wire material of frost formation medium 10, is adhered to the round wire material, cooled under cooling atmosphere, as frost. Dry air, injected out of an air nozzle 30, oscillates the frost formation medium 10 to vibrate the same. The vibration is transferred from respective round wire materials of mesh structure to frost S, adhered to the round wires of the frost formation medium 10. As a result, the frost S is slipped along an interface between the round wire and the frost S and, thereafter, is separated and dropped from the round wires.
