摘要:
Disclosed are an apparatus and a method for bonding electronic components, a circuit board, and an electronic component mounting apparatus, whereby various kinds of circuit boards can be manufactured, each by a small amount, with high productivity as compared with the conventional art. There are provided a stage member and a heating device, so that a circuit board is heated by the heating device while held in contact with the stage member, which stage member has a size almost equal to that of one circuit board. Generation of losses can be reduced for compact circuit boards, and heating can be performed individually, correspondingly, for each kind of circuit board. Manufacturing various kinds of circuit boards, each by a small amount, with high productivity as compared with the conventional art is enabled accordingly.
摘要:
An object of the present invention is to provide a highly sensitive semiconductor light receiving device wherein the efficiency of light convergence into the light receiving region has been increased. The semiconductor light receiving device includes a light receiving region formed on a semiconductor substrate, and an electrode formed in a peripheral portion of the light receiving region on the semiconductor substrate for transferring a charge generated through photoelectric conversion in the light receiving region to the outside of the light receiving region, wherein a part of or the entirety of the peripheral portion of the electrode is processed so as to recede toward the center of the electrode as the electrode is away from the semiconductor substrate. In addition, two types of etching of isotropic etching and anisotropic etching are used at the time of the pattern formation of the electrode at least once, respectively.

摘要:
A control apparatus for input screens includes a display unit, a switch portion and a control unit including a microcomputer. If one of a menu switch of the switch portion and a plurality of dummy switches included in a screen displayed by the display unit is operated, the microcomputer causes the display unit to display a new screen including a plurality of dummy switches. The microcomputer estimates a time period required for the operator to watch a screen to operate the dummy switch, depending on the displayed screen (the number of dummy switches). If the sum of estimated time periods exceeds a reference time period, the microcomputer nullifies operation of the dummy switch to prevent the screen from being switched. After the lapse of a predetermined time period, the microcomputer cancels the nullification of the operation of the dummy switch.
