    摘要： A susceptor support shaft for an epitaxial growth apparatus capable of forming a high quality epitaxial film by suppressing in-plane resistance variation of the epitaxial film due to deflection of a susceptor, wherein the susceptor support shaft supports a susceptor at an underneath portion of the susceptor in an epitaxial growth apparatus. The susceptor support shaft includes a support column located substantially coaxial with a center of the susceptor; a plurality of arms extending radially from the support column to positions under a peripheral portion of the susceptor; an arm connecting member connecting tips of the arms next to each other; and support pins extending from the arm connecting member, thereby supporting the susceptor.

    摘要： The invention relates to a method of manufacturing a stamper with a uniform groove having a width smaller that the beam diameter of the exposure light spot for use with the optical information recording medium. In the method of manufacturing the stamper for exposing and developing the photoresist layer on the glass base plate, a water-soluble resin layer having a film thickness equal to the depth of the groove formed on the surface of the stamper is provided between the glass base plate (master plate) and the photoresist layer. A micro-pattern is formed on the photoresist layer by way of exposing the master plate. The photoresist layer is used as a mask. A micro-pattern is formed on the lower layer (water-soluble resin layer), by etching the water-soluble resin layer. Thereafter, the photoresist layer is removed. In this way, the glass master plate has a micro-pattern formed thereon.

    摘要： An NC-EDM machine is safeguarded against feed errors arising from both mechanical and erosive-machining effects. The disclosed safety arrangement includes two detecting circuit units. The first unit is arranged to respond to NC-furnished driving command signals for producing a first detection signal representative of a commanded relative displacement to be effected between the tool electrode and the workpiece along a programmed machining path in a given time period. The second detecting unit is arranged to respond to effective electrical discharges caused in the EDM gap to produce a second detection signal representative of an actual relative displacement effected between the tool electrode and the workpiece along the path in the given time period. A comparator is connected to the two detecting units for comparing the first and second detection signals to produce an output signal indicative of a deviation of the actual advancement from the commanded advance.
