摘要:
A grating forming method for forming a fine grating with a grating period of at most 1 μm on a surface of a blank material including (1) feeding realatively a diamond cutting tool and the blank material in a groove extended direction while rotating the diamond cutting tool about the axial line and (2) cutting the surface of the blank material with a blade tip part of the diamond cutting tool to form the grooves while rotating and feeding the diamond cutting tool. When the fine grating with the grating period of “P” μm is formed and the feed amount per revolution of the diamond cutting tool is set to be “S” μm, the feed amount per revolution “S”, with which the diamond cutting tool is fed in the groove extended direction while rotating the diamond cutting tool about the axial line, is set to satisfy the following conditional expression: S

A server capable of eliminating the inconvenience which is caused when a request is made after a “back” operation on a client's browser. A request from a client is received, and processed in compliance with the received request. Confirmation information for confirming a display status of the client side is affixed to a result of process, stored, and transmitted. When a request is made again from the client, the confirmation information included in the request is extracted, and it is determined whether the extracted confirmation information extracted coincides with the stored confirmation information. A process performed in compliance with the request is withheld if it is determined that the two sets of confirmation information do not coincide.

A robot control apparatus with great safety is provided by detecting access of a teacher to a robot and automatically reducing the operating speed of the robot when the teacher accesses the robot. The robot control device equipped with a pendant (10) to be manipulated by a teacher, for controlling the operation of a robot on the basis of an operation command from the pendant (10), includes a detecting device (8) for detecting the position of the teacher; a signal processing unit (11) for receiving a signal from the detecting device to produce the position information of the teacher; and a limited speed selecting unit (12) for selecting the operating speed of the robot on the basis of the position information. The robot is controlled at the maximum speed set at the operating speed selected by the limited speed selecting unit (12) on the basis of the operation command from the pendant (10).

A data processing system which allows a client to request or release multiple computing resources with a single action. A grouping unit defines groups of resources, and those groups are maintained by a group manager. When a request is received from a client demanding a specific group of resources, a detection unit finds such a member resource of the requested group that is currently used by any other client. If the detection unit has found a member resource in use, then a determination unit determines whether the detected member resource is to be modified. A permission unit permits the requesting client to make access to the requested group of resources if the detection unit finds that none of the member resources of the requested group are being used by any other client, or if the determination unit finds that neither the current user nor the requesting client intends to modify the detected member resource in use.

A discharge lamp operation apparatus includes an AC power supply (10), a voltage converting circuit (11), an inverter circuit (13), a load circuit (15), a controller (1), and a pulse voltage superimposing section (3). The pulse voltage superimposing section (3) controls the switching elements (Q3, Q4) of the inverter circuit (13) to superimpose a pulse voltage to the voltage applied across the discharge lamp (LA). The period until the discharge lamp (LA) is lighted is divided into a preheating period to preheat the discharge lamp and a startup period to start the discharge lamp. During the startup period, the controller (1) raises gradually the output voltage (Vdc) of the voltage converting circuit (11), and the voltage superimposing section (3) superimposes the pulse voltage on the voltage applied across the discharge lamp (LA).

The current method and system generates an animation sequence for a live character during communication. In response to a performer's voice and other inputs, the animation sequence of the character is generated on a real-time basis and approximates human speech. The animated character is capable of expressing certain predetermined states of mind such as happy, angry and surprised. In addition, the animated character is also capable of approximating natural movements associated with speech.
摘要:
A stamp unit 1 is formed so that the circumference of the stamp material 3 is made as a slant surface 83 by heat-pressing both the lower end 4a of the holder 4 and the circumference of the stamp material 3. The lower end 4a of the holder 4 is formed in a wedge 82 so as to hook the circumference of the stamp material 3. Thereby the stamp material 3 can be surely retained to the holder 4, and the stamp material 3 and the holder 4 can be firmly sealed. As a result, stamping durability is remarkably improved when many stamping operations are repeated.

Apparatus and process for synthesizing a diamond film of high purity at a high rate. Mixture gas of hydrocarbon gas and hydrogen gas is introduced into an arc discharge to produce a gas plasma. This gas plasma is blown against a substrate to deposit diamond. A plasma current power supply is connected with a third electrode disposed above the substrate to place the third electrode at a positive potential. An electrical current is supplied into the gas plasma from the third electrode. Flow of the electrical current through the plasma promotes the decomposition of the hydrogen and hydrocarbon. A diamond film of high purity can be deposited at a high rate. The invention is characterized in that the substrate is placed at a lower potential than the third electrode or the direction of the electrical current intersects the flow of the gas plasma although the electrical current is passed through the plasma. Therefore, it is unlikely that the accelerated electrons reach the substrate, elevating its temperature. Hence, diamond of high quality can be synthesized.

An electronic component mounting apparatus includes a table for feeding in and out a printed circuit board and holding the board thereon, a supply section for supplying an electronic component, a head portion for suctioning the component thereto and mounting the component on the board, an XY-robot for placing the head portion at an arbitrary position, a suction device for suctioning the component thereto, arranged at the head portion and vertically moving with respect to the head portion, and having a function of placing the component in a rotational direction thereof, a recognizing camera for recognizing the component and measuring an error amount of a position of the component before and after correction of the position of the component, and a controller for controlling the head portion, the XY-robot, and the camera. The error amount of the position of the component is measured after the suction device suctions the component thereto, the position of the component is again measured after the correction of an erroneous position of the component in the rotational direction is accomplished, and the component is mounted on the board after the correction of the erroneous position of the component is accurately accomplished.
