摘要:
In a positioning apparatus (40), a fixed scroll (34) is positioned with respect to an assembly body (11) in which a compressor motor (25) has been incorporated. In positioning the fixed scroll (34), electric power is supplied to the compressor motor (25) from an inverter (81) to rotate a crank shaft (20) by the compressor motor (25), thereby shifting a movable scroll (31). In the positioning apparatus (40), the shift of the movable scroll (31) leads to calculation of an appropriate position of the fixed scroll (34). A striking unit (70) applies impact force to the fixed scroll (34) to stir the fixed scroll (34) to the appropriate position.

There is provided a metal/ceramic bonding substrate having improved reliability to heat cycles, and a method for producing the same. In a metal/ceramic bonding substrate 10 wherein a circuit forming metal plate 14 is bonded to one side of a ceramic substrate 12 and a radiating metal base plate 16 is bonded to the other side thereof, at least part of the ceramic substrate 12 is embedded in the metal base plate 16. The ceramic substrate 12 is arranged substantially in parallel to the metal base member 16.
摘要:
A releasing device of the present invention selectively moves one of a pair of conveying members for conveying a sheet into or out of contact with the other conveying member. A first moving device moves the one conveying member into or out of contact with the other conveying member. A second moving device 72is connected to the first moving device for moving the one conveying member in a releasing direction independently of the operation of the first moving means.

In a ceramic circuit board having a ceramic substrate and a metal circuit plate bonded to one surface of the ceramic substrate, assuming that the warpage of the ceramic circuit board is a difference in height between the center and edge of the metal circuit plate and is positive (+) when the circuit board warps so as to be concave on the side of the metal circuit plate, the warpage of the ceramic circuit board is in the range of from −0.1 mm to +0.3 mm when the ceramic circuit board is heated to 350° C., and in the range of from +0.05 mm to +0.6 mm when the temperature of the ceramic circuit board is returned to a room temperature after the ceramic circuit board is heated to 350° C. The initial warpage of the ceramic circuit board is in the range of from +0.05 mm to +0.6 mm.

A portable device includes a portable device body, a touch panel provided on a surface of the device body, and a cover pivotally coupled to the device body for covering the touch panel when it is closed and uncovering the touch panel when it is opened. The portable device further includes a window provided at the cover to allow the touch panel to be seen through the window when the cover is closed. The portable device further includes a button provided at a position on the cover corresponding to the touch panel. The button is operable from an outer side of the cover to control an operation of the touch panel while the cover is closed. A concentrator includes a concentrator body and a device receiving unit attached to the concentrator body for receiving therein the portable device so as to perform data transmission and reception and/or power feeding relative to the portable device. The device receiving unit is capable of receiving the portable device of any size within a given range and performing the data transmission and reception and/or the power feeding relative to the portable device received therein.
摘要:
A plurality of combinations of overcurrent detection voltages and delay times are set in a charge and discharge control circuit. Accordingly, a charge and discharge control circuit is formed in which an overcurrent condition having unexpectedly large consumption current, such as a short circuit, does not damage the circuit. In one embodiment, the charge and discharge control circuit comprises a pair of external connection terminals connected to a secondary cell, a switch circuit connected between the cell and at least one of the external connection terminals, an overcurrent detection element connected in series with the power source for producing an output voltage in accordance with a current flowing therethrough, a voltage detecting circuit for determining whether the output voltage of the overcurrent detection element is above one of a plurality of overcurrent detection voltage levels and outputting an overcurrent detection signal for controlling the switch circuit to disconnect the power source from the external connection terminal, and a delay circuit for delaying the overcurrent detection signal by a delay time which depends upon the level of the output voltage of the overcurrent detection element.
