In order to provide a reactor power control apparatus which can maintain a stable water level when reactivity control based on control rod operation and water level adjustment is performed, this invention comprises a turbine control which calculates the load set error signal from the error between the set target generator power value and the generator power that was fed back and outputs to the turbine control apparatus; control rod control in the natural circulation boiling water reactor which calculates the control rod operation signal and outputs it to the control rod drive control apparatus; water level control inside the natural circulation boiling water reactor which calculates the water level set signal and outputs it to the feed water control apparatus; and the switch determining device which selectively outputs one of the control rod control and water level control based on the generator power that was fed back, the reactor power and water level, as well as switching rules and determination values.

An electrical connecting box suitable to widely-ranging temperature conditions from high temperature to low temperature inside the engine room of a vehicle is described, having a printed circuit board 300 and a first protecting member 100 and a second protecting member 200 housing the printed circuit board in a sandwich state. In this electrical connecting box an extended portion 310 being a part of electrical parts is formed upon a board surface 301 on the side of the first protecting member of the printed circuit board. Additionally, first pillar portions 110 and a second pillar portion 120 are formed upon the inside surface of the first protecting member facing one side of the board surfaces, and a tip 111 and a tip 121 of these pillar portions, according to bending of the first protecting member, can be in either a contacted state or a spaced state with respect to the board surface 301 or, alternatively, a projecting body 321 fixed to the board surface. When the first pillar portions are contacting the one side of the board surfaces, there is a gap between the extended portion and the inside surface of the first protecting member such that they do not interfere with each other.

An image forming apparatus includes at least one image bearing member, an intermediate transfer member, a secondary transfer member, and at least one optical sensor. In the image forming apparatus, it is determined that output values of the respective amounts of toner detected by the at least one optical sensor are affected by an impact caused due to a separation of the secondary transfer member from the intermediate transfer member and the output values are ignored as image adjustment input information, when the secondary transfer member separates from the intermediate transfer member during any of writing, developing, and transferring the plurality of image adjustment patterns, if the output values fall outside a given range and an interval between the output values of adjacent image bearing members is substantially equal to a distance between the two adjacent image bearing members for the primary transfer.

An image forming apparatus is configured that a developing unit develops a latent image with a toner, which is controlled by a toner-supply control unit based on a deference between a toner-density of the toner that is supplied to the developing unit and a reference-value. A reference-value determining unit determines the reference-value. A condition determining unit determines whether a predetermined condition is satisfied. The reference-value determining unit updates the reference-value with a different reference-value when the condition determining unit determines that the predetermined condition is satisfied.

A device for detecting image information includes an intermediate transfer member configured to hold a pattern image; a detecting unit configured to optically detect the pattern image; a secondary transfer unit configured to contact with and separate from the intermediate transfer member; and a control unit that controls the secondary transfer unit in such a manner that the secondary transfer unit does not contact the intermediate transfer member while the detecting unit is detecting the pattern image, and that controls the secondary transfer unit in such a manner that the secondary transfer unit contacts the intermediate transfer member after the detecting unit finishes detection of the pattern image.

An image forming apparatus, which comprises a toner density detection device for detecting the density of a toner inside a developing device, acquires the number of pixels from inputted image information, calculates the toner replenishment amount from the toner density detection value and the information on the pixels, and thereby performs replenishment control so that excessive replenishment or insufficient replenishment of the toner is not caused. The upper limit value of the amount of toner to be replenished at once to the developing device is changed in accordance with the amount of information on an input image such as the image area, pixels of the input image.

An ink-jet head includes pressure chambers arranged in a row in a row-direction, and a manifold flow passage communicated with the pressure chambers and extending in the row-direction. An ink inflow port is formed at one end of the manifold flow passage. The manifold flow passage has a main portion, a connecting portion, and an extended portion which are arranged in this order from a side close to the ink inflow port. The manifold flow passage is communicated with the pressure chambers at the main portion. The main portion has a constant cross-sectional area greater than that of the connecting portion. A cross-sectional area of the extended portion is greater than that of the connecting portion. The pressure wave, generated in the pressure chamber and propagated to the manifold flow passage, can be efficiently attenuated by the manifold flow passage constructed as described above.
