A non-sliding vacuum gate valve has a valve housing with a valve opening therethrough which is opened and closed by a gate valve body moved by a valve rod. The valve rod moves with linear and tilting movement so that the valve body tilts against the valve seat surrounding the valve opening. The valve rod is moved linearly by cylinder rods extending from a pair of cylinders attached to the valve housing on either side of the valve rod. A cam body having an angular cam slot is attached to a connecting member which spans between the end portions of the cylinder rods above the valve rod. The valve rod has a cam follower engaging the angular cam slot to provide the tilting movement of the valve rod and valve body responsive to the alternate reciprocal vertical movement of the cylinder rods, to open and close the valve opening.

An insulating film including characteristics such as low permittivity, a low etching rate and a high insulation property is formed. Supplying a gas containing an element, a carbon-containing gas and a nitrogen-containing gas to a heated substrate in a processing vessel to form a carbonitride layer including the element, and supplying the gas containing the element and an oxygen-containing gas to the heated substrate in the processing vessel to form an oxide layer including the element are alternately repeated to form on the substrate an oxycarbonitride film having the carbonitride layer and the oxide layer alternately stacked therein.

An object is to form a crystalline semiconductor film including a plurality of semiconductor regions with different average grain sizes by a simple manufacturing process.The surface of a crystalline silicon film 30b is irradiated with a laser beam 5, to crystallize the crystalline silicon film 30b. At this time, in the crystalline silicon film 30b below which a gate electrode 21 and a radiation portion 22 having a large area are provided, part of generated heat energy escapes to the radiation portion 22, and hence the crystalline silicon film 30b is insufficiently melted. For this reason, a formed first silicon region 30c1 has a large average grain size. On the other hand, in the crystalline silicon film 30b below which agate electrode 71 having a small area is provided, generated heat is resistant to escaping, and hence the crystalline silicon film 30b is completely melted. Thereby, the second silicon region 30c2 has a small average grain size.

A thermistor device having a high-speed response to temperature and a large ON/OFF ratio at the operating temperature. The thermistor device comprises a first layer of a first material having a positive temperature coefficient of resistance and a second layer of a second material having a semiconductivity and formed directly on the first layer. As the first material changes from conductive to a semiconductive or an insulative at or near the transition temperature TM-I, the interface between the first and second layer changes to a pn junction.

To provide an eutectic crystalline sugar alcohol representing a single melting peak obtained by differential scanning calorimetry, which does not show any one of problems of requiring the addition of a comparatively large amount of a seed crystal to be added for crystallization and a prolonged aging period of several days for crystal growth as well as problems in production, such as an inefficient and complicated production process, while having excellent taste, low hygroscopicity, and excellent uniformity, grindability, and non-consolidation property; and a manufacturing method thereof, which comprises allowing a liquid composition containing two or more kinds of the sugar alcohol at a predetermined ratio to be added with a powder containing crystals of the same two or more kinds of the sugar alcohol at substantially the same usage ratio as that of the sugar alcohol, and kneading and aging a resulting mixture.
摘要:
An image forming system comprises a request analysis section which analyzes an input image forming process request and specifies a peripheral device for use in executing an image forming process and a judgment section to judge whether or not a version upgrade is performed in the peripheral device. A process execution control section executes the process when it is judged that no version upgrade is being performed in the peripheral device, and instructs an input/output section to display, via a report section, a message indicating a version upgrade being performed when it is judged that a version upgrade is being performed. In this manner, user convenience during version upgrade time is enhanced.

A capacitive pressure sensor is provided. The capacitive pressure sensor includes a glass substrate that has a pair of surfaces facing each other. A first silicon substrate has a fixed electrode passing through the glass substrate to be exposed at one surface and a projection passing through the glass substrate to be exposed at the one surface. A second silicon substrate is bonded to the one surface of the glass substrate and is disposed to face the fixed electrode so as to form a cavity between the second silicon substrate and the fixed electrode.

Disclosed is a golf ball having improved impact resilience, which comprises a core and a cover covering the core, wherein the cover is a lithium neutralized ionomer resion which is a copolymer of 10 to 20% by weight of an alpha, beta-unsaturated carboxylic acid and the rest of ethylene, of which 20 to 70 mol % of carboxyl groups are neutralized with lithium ion, and the ionomer resin has a melt index of 0.5 to 5.0 and a shore D hardness of at least 60. The lithium neutralized ionomer resin may be combined with a di- or tri- valent metal neutralized ionomer resin which is a copolymer of 10 to 20% by weight of an alpha, beta-unsaturated carboxylic acid and the rest of ethylene, of which 40 to 70 mol % of carboxyl groups are neutralized with di- or tri- valent metal ion, and which has a melt index of 0.5 to 5.0 and a shore D hardness of 60 to 80.
