Abstract: A substrate cleaning device includes a chamber, a first processing part and a second processing part. The chamber forms a processing space including a first processing position and a second processing position. The first processing part performs a first process on a substrate disposed at the first processing position in the chamber. The second processing part performs a second process on the substrate disposed at the second processing position in the chamber. A main robot loads and unloads the substrate with respect to the substrate cleaning device by moving a hand holding the substrate. In addition, the main robot receives the substrate disposed at the first processing position by causing the hand to enter the processing space, transporting the substrate to the second processing position, and positioning the substrate.

Abstract: A substrate cleaning apparatus includes an upper holding device holding an outer peripheral end of a substrate, and a lower surface brush contacting a lower surface of the substrate to clean the lower surface. The lower surface brush moves from a state of being separated from the lower surface to contact a first partial region of the lower surface when cleaning of a lower surface central region of the substrate is started. Then, the lower surface brush moves into contact with the lower surface central region on the lower surface. The lower surface brush moves from a state of being in contact with the lower surface to be separated from a second partial region of the lower surface when cleaning of the lower surface central region is completed. At least one of the first partial region and the second partial region does not overlap the lower surface central region.

Abstract: A substrate cleaning apparatus includes an upper holding device holding an outer peripheral end of a substrate, and a lower surface brush contacting a lower surface of the substrate to clean the lower surface. The lower surface brush moves between a contact position where the lower surface brush contacts the lower surface of the substrate held by the upper holding device and a separation position where the lower surface brush is separated from the substrate held by the upper holding device by a certain distance. At the separation position, the lower surface brush rotates at a first rotation speed. At the contact position, the lower surface brush rotates at a second rotation speed higher than the first rotation speed at a time point when the lower surface brush contacts the lower surface and a time point when the lower surface brush is separated from the lower surface.

Abstract: A dielectric filter includes a laminate substrate formed by laminating and bonding a plurality of dielectric sheets, belt-like resonance electrodes formed on predetermined bond surfaces of the dielectric sheets, input/output electrodes formed at predetermined positions of an outer periphery of the laminate substrate and connected to the belt-like resonance electrodes, and earth electrodes formed on the outer periphery of the laminate substrate under a non-connection state with the input/output electrodes. The end portions of the belt-like resonance electrodes extend to both side surfaces of the laminate substrate. One end of each belt-like resonance electrode is connected to the earth electrode formed on one of the side surfaces of the laminate substrate and serves as a short-circuit terminal, and the other end of the belt-like electrode is exposed on an ungrounded portion on the opposite side surface and serves as an open terminal.

Abstract: In a laminated dielectric resonator and filter having a folded microstrip line type resonator structure, an internal-to-external grounding conductor distance within which an open-end-side internal conductor pattern is disposed is selected to be shorter than an internal-to-external grounding conductor distance within which a short-circuit-side internal conductor pattern is disposed. In this constitution, since the front end of the resonator structure is loaded with a capacity, the resonance frequency is lowered so that it is possible to provide a resonator having a reduced longitudinal resonator size with respect to the same resonance frequency. In addition, since the resonator has no steps, manufacture and mounting are easy. Accordingly, it is possible to reduce the sizes of the laminated dielectric resonator and filter to a further extent, whereby it is possible to reduce a resonator or filter mounting area in a device.

Abstract: A reflective optical rotary encoder device detects an angular speed or position of a rotatable member with a light beam applied to and reflected from a reflective optical encoder disc. The reflective optical rotary encoder disc has an annular encoder track for reflecting the light beam, the encoder track being composed of an annular pattern of angularly spaced pit units each including a plurality of radially spaced arcuate pits, and a pit-free annular focus servo track for focusing the light beam onto the encoder track, the focus servo track extending along and being disposed radially substantially centrally in the annular encoder track.

Abstract: A reflective rotary optical encoder device for detecting an angular speed or position of a movable member includes an optical encoder disc rotatable with the movable member, the optical encoder having an encoder track composed of a series of equally spaced pits alternating with inter-pit lands therebetween, the pits and the inter-pit lands having equal lengths l. A laser beam pickup applies three laser beams as respective laser beam spots to the optical encoder and detects laser beams reflected from the laser beam spots on the optical encoder to produce electric signals representative of the encoder track. Adjacent light beam spots on the optical encoder are spaced at a pitch P expressed by: ##EQU1## where n is an integer of 1 or more. The length l may be substantially the same as or larger than the diameter of each of the laser beam spots.

Abstract: An optical detection system for detecting a displacement amount of a movement device with an optical encoder movable in accordance with a movement of the movable device has on a light-reflecting layer a plurality of pits successively strung in a predetermined direction. An optical pickup optically picks up the pit information by irradiating the optical encoder with light beams and receiving reflected light beams from the optical encoder. The optical pickup comprises a light-division device for dividing the light beam from a light-emitting device into three light beams so that the divided three light beams are directed to the pit string to apply three light spots to the pit string. The light-division device is adapted to be rotatable with respect to the optical encoder so that a light passing through the three light spots intersects the pit string at a predetermined angle.
