To prevent a reduction in an amount of an ion emission while preventing generation of electromagnetic noise. A high-voltage generating circuit section () that supplies a high voltage to an ion generating element () that generates ions is housed in a housing (), and sealed with filled resin (). An emission port () for emitting the generated ions is formed in the housing (), and an outer surface of the housing except the emission port is covered with a shield case (). A passage port () communicating with the emission port is formed in the shield case. A periphery of the passage port of the shield case is covered with an electrically insulating covering sheet () so that emitted ions do not adhere to the shield case. The ions emitted from the emission port do not adhere to the shield case covered with the covering sheet.

Ion generating device

In an air-conditioner control unit, when pollen mode control is set by a vehicle occupant to perform the pollen mode control that can provide a defogging effect while maintaining the pollen removal effect, the opening of an air inlet door is forcibly set to an inside-air introduction mode (S) when the following two conditions hold: ambient temperature Tam is higher than a threshold (5 to 6&#xb0; C.) set in a low-temperature region (S), and a compressor system is able to operate normally without causing an abnormal pressure (S). If even one of these conditions does not hold, the opening of the air inlet door is not forcibly set to the inside-air introduction mode, and the air inlet door is operated as in normal control. In this way, in the pollen mode control, since the pollen removal effect in the inside-air introduction mode is enabled only when the ambient air is relatively high, the occurrence of windshield fogging can be suppressed.

Automotive air-conditioning system

In an automotive air-conditioning system, when pollen mode control is effected by a vehicle occupant, air outlet mode is forcibly set to a face mode. Further, the air flow amount determined from the air flow amount Vm used in the usual auto mode and the air flow amount f(Tw) used during warm-up control or the air flow amount determined by the air flow amount correction value f(Tam) having a relatively small upper limit value when ambient temperature is higher than a predetermined temperature (15&#xb0; C.), whichever is larger, is taken as the set value for the air flow amount in the pollen mode control. With this arrangement, when coolant temperature and ambient temperature are low, a relatively small amount of air can be blown to the upper part of the occupant's body, and thus, while maintaining the pollen removal effect, occupant discomfort can be reduced by preventing a fast flow of air from being blown toward the occupant's face, etc.

A vehicular air-conditioner with a pollen mode setting intake to an inside air mode, vents to a face mode, and a blower air flow to a limit maximum air flow Mbetween a minimum air flow Lo and a maximum air flow Hi (Lo&#x3c;M&#x3c;M&#x3c;Hi), with an air-conditioning unit provided with a filter for trapping pollen and blowing clean air from which pollen has been removed from the vents to the vehicle compartment, whereby by starting the pollen mode simultaneously with the start of the engine, clean air is immediately blown to the vicinity of the face of the driver from the face vents and thereby the pollen entering the vehicle or pollen carried into the vehicle in the vicinity of the face is blown away, the air flow at this time being a maximum air flow Mable to be withstood in terms of temperature sensation, so a pollen free comfortable environment being created without causing discomfort.

Vehicular air-conditioner

A filter corrugated in wave shape along a first axis has an end filter material piece positioning at an end of the first axis and adjacent filter material piece positioning adjoining to said end filter material piece. The end filter material piece and said adjacent end filter material piece are adhered to each other by an adhesive. In another embodiment, a filter element has a cushion material disposed between the end filter material piece and the adjacent end filter material piece. A filter material has convex and concave crease portions alternately disposed along a first axis thereof and extending along a second axis thereof. The convex and concave crease portions define alternating convex and concave spaces therein. An elastic material fills at least a portion of at least one of said concave and convex spaces.

Filter and filtering apparatus

In a liquid crystal display apparatus in which a selection signal is simultaneously applied to two scanning signal lines, the application of the selection signal to one of the two scanning signal lines is terminated earlier than that of the selection signal to the other one of the two scanning signal lines. Alternatively, the level of the selection signal to one of the two scanning signal lines is made higher than that of the selection signal to the other one of the two scanning signal lines.
