Abstract:
A method of producing the silicon nitride sintered body includes the steps of forming a compact of molding materials including silicon nitride powder, a Mg component and a sintering aid, and sintering the molding materials at 1,800 to 2,000° C. under a nitrogen atmosphere. The materials at least include an oxide of Mg in a range of 0.3 to 10 wt. %. A constant temperature is kept for at least 0.5 hours in a temperature range of 1,400 to 1,700° C. before the temperature is increased to the sintering temperature. A silicon nitride body having high thermal conductivity and excellent electrical insulation properties at high temperature can thus be provided.
Abstract:
A conveyance system in a semiconductor manufacturing process comprises a process unit processing a semiconductor wafer, a conveyer conveying the semiconductor wafer, a conveyer controller controlling the conveyer, and a computer controlling the conveyer and the conveyer controller. In the system, the process unit sends a warning signal to said computer, indicating time of the process completion in the process unit before the process is completed, and the conveyer is moved to the process unit in response to the warning signal.
Abstract:
A method for bonding a chip part, having solder bumps on the underside thereof, to a base material. The method includes the steps of placing the chip part at a specific position on the base material, placing a weight on the chip part, the weight being based on the number of solder bumps mounted on the chip part and a surface tension of the solder bumps at melting, and irradiating, with an electromagnetic wave, an upper surface of the weight to transfer heat to the solder bumps through the weight and the chip, thereby melting the solder bumps and bonding the chip part to the base material.
Abstract:
A system test apparatus for verifying whether or not a tested system works according to particular specifications is disclosed. The system test apparatus comprises a storage device for storing the particular specifications as a finite state machine model including elements represented with time sections which may take place, a detecting device for periodically detecting operation information which represents an operation of the tested system as a combination of events and actions represented with the time sections which may take place and a verification device for comparing the operation information with the particular specifications stored in the storage device according to the finite state machine model. In the above finite state machine model, events, actions, and the like are represented with time sections which may take place.
Abstract:
This invention provides a communication apparatus, which designates, when a line designated as that used for a specific application falls into a disabled state, another line as a new line used for the specific application. To accomplish this, even when at least one of a plurality of lines falls into a disabled state, and when the line in the disabled state is designated as a line used for the specific application, the communication apparatus designates a line other than the line in the disabled state among the plurality of lines as a new line used for the specific application.
Abstract:
An image processing apparatus includes a receiving unit configured to receive a job ticket from an information processing apparatus, a determination unit configured to determine whether it is permitted for a user to use an extended function not included in functions described in function information defined in the job ticket received by the receiving unit, and a control unit configured, if it is determined by the determination unit that it is permitted for the user to use the extended function, to permit execution of processing on image data that uses a function described in the function information defined in the job ticket received by the receiving unit and execution of processing that uses the extended function.
Abstract:
There is provided a bonding material composition for obtaining a joined body by unitarily joining two or more members to be joined by means of a bonding material layer, wherein the bonding material composition contains flat particles, non-flat particles, smectite-based clay, and an inorganic adhesive as main components. The bonding material composition costs little, can relax thermal stress generated in the joined body without using fibers which may do harm to a human body, and can reduce defects such as a crack and a void upon drying or a thermal treatment.
Abstract:
The invention relates to an optical apparatus having a vibration detector that detects vibration, a holding member that holds an image stabilizing optical system, an elastic member that elastically supports the holding member so that the holding member can shift within a plane perpendicular to an optical axis, a drive unit that generates a drive force resisting against an elastic force of the elastic member, a drive circuit that drives the drive unit, a control circuit that controls the position of the holding member, a temperature sensor that measures temperature, and a viscous damper that damps movement of the holding member in the drive direction. The control circuit changes the image stabilizing drive control characteristic of the drive circuit to compensate for changes in viscosity of the viscous damper with temperature.
