A method of mounting a chip in which an underfill agent having specific viscosity behavior and a trigger temperature is applied to at least one of a substrate and the chip, bumps are press-contacted to electrodes, the underfill agent is spread around the press-contacted bumps and the electrodes between the chip and the substrate, the bumps are melted by heating while the bumps are embedded in the underfill agent to bond the molten bumps and the electrodes, and in melt-bonding the bumps, a time to wet-spread the molten bumps is kept before the underfill agent is cured. Highly reliable excellent bonding between the bumps and the electrodes can be achieved by thoroughly wet-spreading the molten bumps while secondary oxidation in the underfill agent does not occur, and the time required until the underfill agent is cured to a specified state, and further resultantly, the time required until the press of the chip is stopped can be shortened. By this method, drastic simplification of the mounting process in total and drastic shortening of the tact time are possible.

A ceramic holder 2 is mounted on the lower end of a connecting block 30 of metal mounted on the lower end of a tool main body 1 of metal, such ceramic holder 2, a ceramic heater 4 and a ceramic presser 5 being sintered. In addition) the coefficient of linear expansion of the ceramic holder 2 is approximately equal to those of the ceramic heater 4 and ceramic presser 5; furthermore, the thermal conductivities of the ceramic holder 2 and ceramic presser 5 are greater as the pressure side of the ceramic presser 5 as seen from the ceramic heater 4 is approached and are smaller as the attaching surface side of the ceramic holder 2 is approached.

To provide a vacuum pump that may heat a flow path of gas effectively with small electric power. A vacuum pump provided with an outer sleeve, a stator received in a hollow portion of the outer sleeve, a rotor received rotatably within the hollow portion of the outer sleeve for forming a flow path of gas in cooperation with the stator, a base to which the outer sleeve and the stator are to be fixed and supported, a heating electromagnet for generating heat by current supply and forming a magnetic field, a magnetic member forming a magnetic path of magnetic force by the heating electromagnet, and a heat radiation plate made of aluminum and fixed to the magnetic member.
摘要:
A vacuum pump comprises an inlet port into which a gas is introduced, an outlet port from which the gas is discharged, a stator, a motor, and a rotor opposing the stator and driven by the motor to undergo rotation to cooperate with the stator to force the gas from the inlet port to the outlet port. The rotor has a body, a spiral thread disposed on the body, and a thread groove disposed between adjacent lines of the spiral thread. An axial length of the spiral thread is shorter than an axial length of the rotor so that a terminal end portion of the spiral thread terminates short of an axial end of the rotor. The terminal end portion of the spiral thread slopes inward toward a surface portion of one of the thread grooves. A junction surface between a terminal end portion of the slope of the spiral thread and the surface portion of the thread groove forms a recessed portion.

To provide magnetic bearing devices capable of preventing undesirable consequences caused by conical mode or parallel mode resonance which is liable to occur during acceleration of a rotor. A band-pass filter 24 is connected in series with a PID control circuit 12 is for improving stiffness in a specific frequency band. A displacement of a rotor 2 detected by a displacement detector 30 is entered to a switcher 32. On the other hand, a rotational speed sensor 7 detects the revolving speed, and a compensator switching discriminator 26 causes a switch 32s of the switcher 32 to connect to an output terminal 32b or to an output terminal 32c when the revolving speed coincides with preset revolving speed data. The preset revolving speed data defines specific revolving speeds occurring below and above a frequency band which includes a first conical mode resonant frequency and a second conical mode resonant frequency. The position of the rotor 2 is adjusted by a magnetic bearing 38 based on an output of the PID control circuit 12.
