  • Patent number: 11915947
    Abstract: Substrates can be suppressed from being separated from supporting grooves. A substrate processing apparatus includes a substrate holding unit and a processing tub. The substrate holding unit is configured to hold multiple substrates. The processing tub is configured to store a processing liquid therein. The substrate holding unit comprises a supporting body, an elevating device and a restriction unit. The supporting body has multiple supporting grooves and is configured to support the multiple substrates with a vertically standing posture from below in the multiple supporting grooves, respectively. The elevating device is configured to move the supporting body between a standby position above the processing tub and a processing position within the processing tub. The restriction unit is configured to be moved up and down along with the supporting body by the elevating device and configured to restrict an upward movement of the substrates with respect to the supporting body.

  • Patent number: 6564480
    Abstract: In a working apparatus, a recessed portion is formed at an end surface of a pin provided at a boom to house a case of an angle sensor in the recessed portion. A flange is projected from the case along the direction of the axis of an input shaft so as to enclose the input shaft outside the movement range of a lever. By projecting the flange further out than the distance over which the input axis projects out, the protection provided by the flange for the input shaft is enhanced.
