Abstract: A variable nozzle device 20 for a variable geometry turbocharger includes: a nozzle mount 21; a nozzle plate 22 disposed so as to face the nozzle mount, the nozzle plate forming a nozzle flow passage 4 having an annular shape between the nozzle plate 22 and the nozzle mount 21; and a plurality of variable nozzle vanes 6 disposed at a predetermined interval in a circumferential direction of the nozzle flow passage 4 so as to be individually rotatable about a pivot axis O2. The nozzle plate 22 includes a first surface 33 facing the nozzle mount 21, a second surface 34 opposite to the first surface 33, and at least one through hole 36 formed through the first surface 33 and the second surface 35.

Abstract: A numerical controller for a grinding machine, wherein one of plural reference sizing points is selected according to the contents of a numerical control program. Measured analog data indicating the diameter of a workpiece is received continuously to determine if the size of the machined workpiece coincides with the selected reference sizing point. Upon the coincidence of the size of the machined workpiece with the reference sizing point, a sizing signal is provided, and then machining control is changed in response to the sizing signal. An analog signal provided by a measuring device is sampled at a predetermined interval in a predetermined time. The analog signal is tested to see if the analog signal is in a predetermined range, which is decided based upon the temperature variation or vibrations of the grinding machine. And the result of the test is displayed to facilitate checking the output characteristics of the measuring device.

Abstract: The present invention relates to a reinforced corrugated board which is specifically reinforced in only those locations where such reinforcing is required in the product produced from this board. The board has a smooth top face or liner and a first corrugated layer adhesively affixed therebeneath. To the bottom of the first corrugated layer, a second corrugated layer is affixed. This second layer is only as large as the area requiring special reinforcing in the final product and need not be as large as the first corrugated layer. A bottom liner or facing is affixed to the second corrugated layer and any of the first corrugated layer which extends around the second layer.An apparatus and method for producing this board sheet are also presented.
