There is provided a process for producing an aromatic hydroxycarboxylic acid which is capable of suppressing the formation of by-products and enhancing the selectivity of the intended product and is free from any purifying step. The process is characterized in that it is obtained by reacting an alkali metal salt of an aromatic hydroxy compound and carbon dioxide in a non-proton polar solvent in the presence of a solid basic catalyst.

An image processing apparatus includes an estimating unit and a hiding unit. The estimating unit extracts a subject specifying mark image corresponding to a specifying mark from a recording area image corresponding to a recording area in which an image is recorded, plural predetermined types of specifying marks having predetermined attributes different from an attribute of the image of the recording area and being used for specifying a region within the recording area by using different specifying methods, at least one of the plural predetermined types of specifying marks being recorded in the recording area. The estimating unit estimates the type of specifying mark corresponding to the extracted subject specifying mark image. The hiding unit hides the region specified by the type of specifying mark estimated by the estimating unit by using a hiding method which is uniquely determined for the estimated type of specifying mark.

An image processing apparatus includes following components. A blank-area identifying unit identifies a blank area having a size exceeding a predetermined size, from a non-specifying-mark image portion of a recording area image of a recording area that includes individual images and a specifying mark specifying an area containing images among the individual images. A concealing unit conceals a divided area specified by the specifying-mark image, among divided areas obtained by dividing a non-blank area by a gap having a width equal to or larger than a threshold in a specific direction, among gaps between the individual images arranged in the specific direction in the non-blank area. The non-blank area is an area of the non-specifying-mark image portion of the recording area image other than the blank area identified by the blank-area identifying unit.

A hydroforming apparatus and working method able to simply find a load path are proposed, which system and method use a mold in which contact sensors able to judge contact with a metal tube inside the mold are mounted at least at two different positions in the tube axial direction, perform a first step of axially pushing tube ends in a state with the internal pressure held at a constant value and stopping the progress of the axial pushing action when judging that among the contact sensors not yet in contact mounted at positions closest to the tube ends detect contact with the metal tube, next perform a second step of raising only the internal pressure while leaving the positions of the tube ends fixed and stopping the increase in the internal pressure when the contact sensor not yet in contact judges contact, next perform a third step of lowering the internal pressure to the value before raising it while leaving the positions of the tube ends fixed, and repeat said first step to third step until all of said contact sensors judge contact so as to obtain a hydroformed part.

According to one embodiment; an antenna device according to this embodiment includes the first antenna element formed from a folded monopole element and a capacitor element. The first antenna element has a first end connected to a feeding terminal, a second end connected to the first ground terminal, and a middle portion folded, with a stub being provided between the forward portion and backward portion formed by this folding. The capacitor element is inserted between the stub and the above feeding terminal of the forward portion of the first antenna element.
摘要:
The object is to raise the yield by greatly eliminating the disposed amounts of the tube ends, prevent wrinkles due to closing the mold while applying internal pressure, cutting the plurality of steps of hydroforming and pre-processing of the tube ends, cutting the mold costs by simplifying the mold mechanism, and obtaining a hydroformed product formed with a flange along its entire length.For this reason, the present invention provides a hydroforming method which places a metal tube to a lower mold in the state with the tube ends sticking out from it and injects a pressurizing fluid into the metal tube through the inside of a seal punch and gradually presses seal punches against tube ends of the metal tube to apply a predetermined pressing force and fill the inside of the metal tube with the pressurizing fluid to apply a predetermined internal pressure, next, in the state with the internal pressure and pressing force applied, lowers the upper mold and closes the mold so as to deform the tube and end the processing in the state with the tube ends sticking out from the mold, and, further, boosting the internal pressure in the metal tube after closing the mold and ending the forming operation and a hydroformed product processed using these methods and having a flange across the entire length in the longitudinal direction.
