A suction chuck and an inner cup are rotated in unison with each other to spread a coating solution uniformly over a planar object in the inner cup under centrifugal forces. Vent holes defined in an outer cup lid which closes an outer cup are held out of communication with vent holes defined in a ring-shaped closure member, so that the interior space in the outer cup is kept out of communication with the exterior space around the outer cup. The concentration of a solvent in the outer cup remains so high that no mist is produced in the outer cup. After the planar object has been coated and before the outer cup lid is opened, the ring-shaped closure member is turned to align the vent holes in the outer cup lid with the vent holes in the ring-shaped closure member, breaking any vacuum in the outer cup with ambient air introduced through the vent holes into the outer cup. Thereafter, the outer and inner cup lids are opened, and the coated planar object is taken out.

According to the invention disclosed, application liquid such as spin-on-glass (SOG) is dropped on the surface of a substrate such as a semiconductor wafer having irregularities thereon and is dispersed on the substrate surface using a centrifugal force generated by rotating the substrate. The rotation of the substrate is performed in a first rotational action at a low speed and a second rotational action at a high speed, the first and second rotational actions being separated by a time interval. The second rotation may be at a constant speed. Alternatively, the rotational speed of the second rotational action may comprise rotation at an intermediate speed continuously followed by rotation at a higher speed. The time interval between the first and second rotational actions is ten times the duration of the first rotational action or longer. The duration of the second rotational action is three times that of the first rotational action or longer. Such time interval and relative durations make the application liquid more conformable to the substrate surface and causes the application liquid to be sufficiently dispersed on the substrate to provide a film having the desired thickness on the substrate, even though the substrate has irregularities thereon.

A hybrid vehicle includes an input device that is used by a user to request an increase in the amount of charge of the power storage device. When a request for increasing the amount of charge is made using the input device, a control device controls charging of a power storage device by a generating device so that charging of the power storage device is promoted, warms a catalyst device by operating an internal combustion engine while limiting the output of the internal combustion engine, and when the warming of the catalyst device and the request for increasing the amount of charge that is made using the input device overlap each other, the control device eases the output limitation of the internal combustion engine.

A hybrid vehicle includes a controller that executes control such that a second motor is regeneratively driven within the range of input and output limits of a high-voltage battery that exchanges electric power with the second motor that outputs power for traveling without running an engine using a first motor when charging electric power is smaller than the input limit of the high-voltage battery and an EV traveling priority mode is set. The invention also relates to a control method for the hybrid vehicle.

A Wout control unit increases a discharge allowable power to W1 greater than W0 when the running mode is at a CD mode and an engine is stopped. An engine operation determination unit determines whether the engine is to be set at load operation or not based on W0 when the running mode is at the CS mode, and based on W1 when the running mode is at the CD mode. In the case where the engine is at no-load operation, the engine operation determination unit determines whether the engine is to be set at load operation or not based on W0 even if the running mode is at the CD mode.

An ECU includes a running mode control unit, a Wout control unit, and an engine start/stop determination unit. The running mode control unit controls switching of a running mode including a CD mode in which an engine is stopped and running using a motor generator alone is given priority, and a CS mode in which the engine is operated and the SOC of a power storage device is maintained at a predetermined target. The engine start/stop determination unit carries out a start determination of the engine based on a discharge allowable power indicating electric power that can be discharged by the power storage device. The Wout control unit modifies the discharge allowable power based on the running mode and operation/stop of the engine.

An ECU executes a program including the steps of: executing first restriction control if the temperature of coolant is equal to or greater than a first temperature and smaller than a second temperature; executing second restriction control if the temperature of the coolant is equal to or greater than the second temperature; and executing normal control if the temperature of the coolant is smaller than the first temperature.

There is provided an IP network system. The IP network system includes: a plurality of relays making up a ring network; a source host for transmitting a packet and connected to the ring network; and a destination host which conducts a packet communication with the source host through the ring network. Each of the relays is operable to transfer received packets containing a transfer direction information to the destination host through a right-handed route of the ring network and through a left-handed route of the ring network, based on the transfer direction information.

A method for forming a coating film, comprises the steps of: applying a raw material of a low dielectric constant onto a surface of a plate-like material; reducing oxygen concentration in the atmosphere surrounding the plate-like material to be less than or equal to 1% before a surface temperature of said plate-like material to be treated rises to 200° C.; thereafter heating said plate-like material to a temperature greater than or equal to 400° C.; and then maintaining the oxygen content in the atmosphere to be less than or equal to 1% until the surface temperature of said plate-like material to be treated lowers to 200° C. The raw material is an organic SOG obtained by hydrolyzing and condensing at least one alkoxysilane compound into an organic solvent under an acid catalyst.
