A slot nozzle assembly for extruding a fluid material includes a slot for extruding a fluid material, a plurality of material exit ports, and a plurality of material dispersion passages communicating with the slot and the plurality of material exit ports, respectively. The widths of the plurality of material dispersion passages in the longitudinal direction of the slot widen from the plurality of material exit ports toward the slot for extruding a fluid material essentially uniformly in the longitudinal direction of the slot.

When the damping time constant Dτ is changed to Dτ=0, the sampling period Ts is automatically changed from 100 ms to 50 ms. The sampling time is automatically changed from 60 ms to 30 ms. Thus, when the damping time constant Dτ is changed to Dτ=0, a processing unit samples an electrical signal corresponding to the pressure difference of a fluid detected by a differential pressure sensor for the sampling time ts=30 ms in every sampling period Ts=50 ms, and finds the measurement value ΔP of the differential pressure by performing a variety of operation processing including a linearization operation and a square root operation on the sampled electrical signal. In the operation processing, the processing unit does not perform a damping operation.

A processing method for a package substrate having a base substrate partitioned by a plurality of crossing division lines to form a plurality of chip forming areas where a plurality of semiconductor chips are respectively formed and molded with resin. The package substrate has a resin surface and an electrode surface opposite to the resin surface. The processing method includes a warp correcting step of cutting the package substrate from the resin surface or the electrode surface along the division lines by using a cutting blade to form a cut groove, thereby correcting a warp of the package substrate, and a grinding step of grinding the resin surface of the package substrate in the condition where the electrode surface of the package substrate is held on a holding table after performing the warp correcting step, thereby reducing the thickness of the package substrate to a predetermined thickness.

A manufacturing method for a stacked wafer configured by bonding a mother wafer having a plurality of first semiconductor device and a stacking wafer having a plurality of second semiconductor devices. The manufacturing method includes the steps of attaching a protective member to the front side of the stacking wafer to protect the second semiconductor devices, next grinding the back side of the stacking wafer, next bonding the front side of a reinforcing wafer through a bonding layer to the back side of the stacking wafer, next dividing the stacking wafer together with the reinforcing wafer into the plural second semiconductor devices, next bonding the front side of each second semiconductor device to the front side of the mother wafer to thereby connect the electrodes of each second semiconductor device to the electrodes of the corresponding first semiconductor device of the mother wafer, and finally grinding the reinforcing wafer bonded to the back side of each second semiconductor device to thereby remove the reinforcing wafer.

An undefill material is provided on the surface of a wafer in such a manner as to cover bumps, then the wafer is irradiated with a laser beam from the surface thereof and along planned cutting lines so as to remove an insulation layer and the underfill material present over the planned cutting lines, and the debris generated in this instance are deposited on the underfill material and are thereby prevented from being deposited on the wafer surface and/or on the bumps. Subsequently, a surface layer of the underfill material is cut so as to make the bumps flush in height and to expose the tips of the bumps.

By using a new pretreatment agent consisting essentially of a carboxylic acid-type cation exchange resin fiber or a siliconized glass fiber, the interfering components and the elements of turbidity present in a subject fluid for immunologic pregnancy test can be specifically removed without entailing a substantial loss of human chorionic gonadotropin contained in the subject fluid.

A hybrid vehicle driving device is capable of causing a motor-powered travel of a hybrid vehicle in which only an electric motor is used as a drive force source, by driving the electric motor with electric power from an electric storage device while a rotational driving of an internal combustion engine has been stopped. A control device for the hybrid vehicle driving device includes a rotational drive portion that determines whether or not supply of a lubrication oil to at least a portion of the power transmission device by the lubrication oil supply device is necessary based on a travel distance in the motor-powered travel following a stop of the rotational driving of the internal combustion engine, and rotationally drives the internal combustion engine based on determination as to need for the supply of the lubrication oil.

摘要:
A hybrid vehicle power transmission device provided with a power distribution mechanism composed of a planetary gear device for distributing motive power of a drive source to a motor and an output shaft is further provided with a damper device in a power transmission path between the power distribution mechanism and a first motor. Consequently, the damper device receives only reaction torque dealt by the first motor through the power distribution mechanism with respect to drive torque of an engine. Thus, since the torque transmitted to the damper device is smaller than the drive torque of the engine, the torque capacity of the damper device can be decreased and the size of the damper device can be reduced. As a result, the overall size of the power transmission device can be similarly reduced.
