  • Patent number: 6436472
    Abstract: A slit nozzle is positioned above an end of a glass substrate placed in an inner cup, and, while a coating solution is being ejected with reduced surface tension from the slit nozzle toward the glass substrate, the slit nozzle is translated parallel to the surface of the glass substrate to roughly coat the coating solution on substantially the entire surface of the glass substrate. Thereafter, the upper opening of the inner cup and the upper opening of an outer cup around the inner cup are closed by respective lids, and then the inner cup is rotated to rotate the glass substrate for thereby spreading the coated solution uniformly over the surface of the glass substrate under centrifugal forces.

  • Patent number: 5344536
    Abstract: An electron cyclotron resonance plasma chemical vapor deposition system has a reaction chamber for introducing a reaction gas therein, the reaction chamber housing a table for supporting a semiconductor wafer. A microwave oscillator is connected to the reaction chamber through a waveguide for generating and introducing a microwave into the reaction chamber to produce a plasma in the reaction chamber for activating the reaction gas to etch or deposit a film on the semiconductor wafer in the reaction chamber. A pair of upper and lower coils is disposed around the reaction chamber for generating respective magnetic fields in opposite directions in the reaction chamber. The magnetic fields cancel out each other creating a region with substantially no flux density in the magnetic fields between the coils. A bias voltage is applied to the table to attract the plasma to the table in a uniform manner.

  • Patent number: 5137144
    Abstract: A conveyor system having conveyor pieces connected together, without gaps, and links having projections engageable with sprockets connected in an endless manner to thereby constitute an endless conveyor. The arrangement permits powdery goods or fluid goods to be conveyed without falling or spilling from the link portions of the loading surface of the endless conveyor. A plurality of side protect fins are placed one on another without gaps on the sides of the endless conveyor in its width direction. This allows powdery goods or fluid goods to be conveyed without falling or spilling from the overlapping portions of the side protect fins at the sides of the loading surface.

  • Patent number: 5131524
    Abstract: Disclosed is a conveyor system with movable partitions, which is so designed that powdery goods, grainy goods or other shapeless goods, or loose stuff, such as molded resin articles, can surely and safely be conveyed, when excessive resistance is applied to the lower end portion of a partition moving within a load-receiving tray, the partition swings rearward to run free of the load, when goods to be conveyed get stuck at the lower end portion of the partition, the partition moves in that state in the tray dragging the goods along, and when the partition reaches the front sprocket in the running direction and the partition-attached portion of an endless caterpillar engages with the sprocket and rotates about a quarter, the partition is flipped over, permitting the goods to be set free or removed.
