A first intake air control mode of setting an intake throttle valve to (or close to) a fully-opened state and setting an EGR valve to (or close to) a fully-closed state is performed when DPF temperature and a particulate matter deposition quantity are greater than corresponding predetermined values respectively, a no-injection operation state exists, and engine rotation speed is higher than a corresponding predetermined value. A second intake air control mode of setting the intake throttle valve to (or close to) a fully-closed state and setting the EGR valve to (or close to) a fully-opened state is performed when the DPF temperature and the particulate matter deposition quantity are greater than the corresponding predetermined values respectively, the no-injection operation state exists, and the engine rotation speed is lower than the corresponding predetermined value.

A liquid discharge head includes a recording element board having a first face on which multiple recording elements are provided, and discharge orifices for the recording elements, where pressure chambers are formed for each recording element and liquid is discharged from discharge orifices. A liquid supply channel and a liquid recovery channel are provided in common to the plurality of recording elements, in a second face opposite to the recording element board from the first face. The pressure chambers are each made to communicate with the liquid supply channel and the liquid recovery channel by the supply ports and recovery ports respectively, and a flow from the liquid supply channel through the pressure chambers to the liquid recovery channel is generated. A composited flow resistance of the liquid recovery channel and recovery ports is greater than a composited flow resistance of the liquid supply channel and supply ports.

A method for breeding beef cattle and mutton sheep standardly on a large scale through photovoltaic facilities includes the four parts that first, a photovoltaic facility greenhouse is built, maize seedlings or high-quality green forage grass Zea mexicana is produced throughout the year to be used as green fodder of beef cattle and mutton sheep; second, the beef cattle and the mutton sheep are bred and bio-organic fertilizer is produced standardly on a large scale through the photovoltaic facility greenhouse; third, photovoltaic power generation is performed for self use, and excessive electricity is connected into the state grid; fourth, a beef cattle and mutton sheep traceable system is built, and foods are made safe and sanitary. Through the method, not only can solar resources be effectively utilized to output clean and green energy, but also efficient planting and breeding can be achieved, by-products are processed into organic fertilizer, and a new path is provided for green agricultural production. Because a full-frame high-standard support system is adopted for the photovoltaic agricultural greenhouse and photovoltaic modules are arranged on the greenhouse, the space of the greenhouse can be effectively utilized, power utilized in the greenhouse can be supplied through a photovoltaic power station, and equivalently, stereoscopic production is formed on the land with the same area.

The present invention provides a self-ballasting fluorescent lamp (1) which can obtains an external appearance that is approximate same to the common illuminating electric bulb and reduces the heat influence of the luminous tube (4) to the electronic component (60) that is configured at the inner side of the lamp holder (2). One end side of the cover body (3) is arranged with a lamp holder (2) andthe other end side of the cover body (3) is supported with a luminous tube (4). The substrate (58) of the lighting device (7) is installed with an electronic component (60) of the light circuit (59)which lights the luminous tube (4). The substrate (58) is formed to a breadth dimension that can be inserted in the inner side of the lamp holder (2) and is longitudinally arranged along the center line direction of the lamp holder (2), the cover body (3) is minimized to obtain an external appearance approximately same to the common illuminating electric bulb. The heat insulating material (64) isarranged at the opening between the longitudinally arranged substrate (58) and the cover body (3). The heating insulating material (64) is used for insulating the heat between the side of the lamp holder (2) and the side of luminous tube (4) and reducing the heat influence of the luminous tube (4) to the electronic component (60) arranged at the inner side of the lamp holder (2). At the inner sideof the lamp holder (2) the front end part of the tubule (38) enveloped with main mercury alloy (39) is thermally connected with one part of electronic component (60) and the lamp holder (2) by the heat conducting material (65).

A printing apparatus includes: a printing device configured to print an image on a sheet; a temperature detector configured to detect a temperature in the printing apparatus; and a controller. The controller executes: a first processing in which the controller changes a first indicator based on printing performed by the printing device; a second processing in which the controller changes the first indicator based on a first temperature detected by the temperature detector at a first point in time and a second temperature detected by the temperature detector at a second point in time; and a third processing in which the controller suppresses a rise in the temperature in the printing apparatus when the first indicator reaches a predetermined value.

An optical scanner for an image forming apparatus has a housing having a wall surface provided with a through-hole, and an optical scanning unit, which is provided within the housing, scans light on an object to be scanned in order to form an image on the object to be scanned, and includes: a polygon motor; a polygon mirror that reflects the light while being rotated by a driving force of the polygon motor; a mirror member that reflects the light reflected by the polygon mirror, toward a target object; and a mirror holding member that is attached to the wall surface of the housing and holds the mirror member. The mirror holding member has a heat radiation part that is exposed to the outside of the housing through the through-hole.

PROBLEM TO BE SOLVED: To provide a washer-dryer machine capable of effectively annihilating mites, while preventing the temperature of laundry such as a blanket having a low resistance against heat from excessively rising in heating, such that the laundry is protected from the heat.SOLUTION: When a heating treatment for supplying warm air into a washing tub is performed, water is supplied into the washing tub by water supply means to perform a cooling treatment for cooling the laundry.SELECTED DRAWING: Figure 1

An inverter is disposed at a position on the upstream side relative to a compression mechanism along the flow of a refrigerant and the position cooled by the refrigerant. A motor is disposed at a position heated by the refrigerant compressed by the compression mechanism. A control device changes an upper limit value of a driving current supplied to the motor on the basis of at least one of first information relating to the temperature of the motor or second information relating to the temperature of the inverter.

The invention provides a refrigerator air door deicing control method and device. The refrigerator air door deicing control method comprises the steps that a motor is controlled to drive an air door to move from the initial position to the target position; the driving current of the motor in the process of driving the air door to move is detected; first motion time of the air door from motion starting to motion finishing is detected; whether the air door has a deicing need or not is judged according to the driving current and the first motion time; and if the air door has the deicing need, a heating wire is controlled to heat the air door for a period of time equal to the preset heating duration, and the motor is controlled to drive the air door to move from the initial position to the target position. The refrigerator air door deicing control device comprises a motion control module, a current detecting module, a time detecting module, a need analysis module and a deicing control module. According to the scheme, the effect of deicing treatment on the air door of a refrigerator can be improved.
