摘要:
A color cathode-ray tube where an electron beam selection mask with an aperture grille type beam selection electrode of a thin metal plate attached to a frame is supported by engagement of stud pins with support springs and is thereby positioned stably opposite to a color luminescent screen formed on the inner surface of a panel. A projection is formed on either the top of each stud pin or the bottom of each cap opposed thereto, while a recess is formed in the other for engagement with the projection in the direction orthogonal to the action of the support spring. The mutual contact portions of such projection and recess are coated with solid lubricant films so that the beam selection mask can be reset at its proper position despite any external impact applied thereto. The elasticity constant of the frame is selectively set at a desired value with additional disposition of reinforcing plates having the same thermal expansion coefficient as that of the frame, thereby averting vibration of the beam selection mask. And rotary mechanisms are formed relative to the support springs and are rotated in accordance with thermal expansion of the frame, so that the frame is shifted toward the panel surface having a color luminescent screen thereon, whereby mislanding of the electron beam due to temperature rise in the beam selection mask can be prevented.

A transformer integrated type printed circuit board includes: a transformer including a core, a primary winding wire, and a secondary winding wire; and a printed circuit board including a surface layer and an internal layer in which wiring patterns are respectively formed, and having a plurality of insertion portions into which a plurality of leg portions of the core are respectively inserted. The primary winding wire is disposed in the surface layer of the printed circuit board so as to be wound between the leg portions, and the secondary winding wire is disposed in the internal layer of the printed circuit board so as to be wound between the leg portions. The primary winding wire is small in number of windings, is large in width, and is large in thickness, in comparison with the secondary winding wire.

A power supply device includes: a power factor correction circuit which includes a capacitor and which corrects a power factor of power; a DC-DC converter which includes a switching element and which steps up or down an output voltage of the power factor correction circuit; a control unit; and a voltage detection unit which detects a voltage of an input side of the power factor correction circuit. The control unit controls the switching element such that an output voltage of the DC-DC converter is gradually reduced when stopping an operation of the DC-DC converter in a normal state in which the voltage detection unit does not detect a voltage lower than a predetermined value. When the voltage detection unit detects a voltage lower than the predetermined value, the control unit immediately turns off the switching element to stop the operation of the DC-DC converter.

A liquid crystal display device includes a liquid crystal display panel having an active area in which pixels are arranged in a matrix including first and second signal lines and connecting lines. The second signal lines and connecting lines extend in a column direction in the active area. The first signal lines extend in a row direction so as to cross the second signal lines and the connecting lines. The first signal lines are connected to the connecting lines through contact portions provided at the cross area where the first signal lines cross with the connecting lines interposing an insulating layer. The second signal lines and the connecting lines are pulled out from the active area to a signal supply source provided at outside of the active area without detouring in a peripheral region of the display panel.

摘要:
A multi-cell battery system includes a plurality of modules connected in series, each of the modules comprising a battery cell and a slave for monitoring a state of the battery cell, and a master for monitoring the state of the battery cell by communicating with the slave of each of the plurality of modules. The master transmits, in order, to the plurality of modules a series of numbers to be numbered on each module as a numbering signal. Each of the plurality of modules numbers the series of numbers in the series-connected order by receiving the numbering signal from the master and executing numbering based on number information contained in the numbering signal when receiving a numbering reception request signal for executing the numbering, and transmitting the numbering reception request signal to a module of a next stage in the series when the numbering is completed.

Provided are scissors with excellent safety that can more reliably prevent finger pinch when being closed. In the present invention, finger pinch prevention guards 20a, 20b for preventing fingertips from entering the opposing inner surfaces 10a, 10b side from above or below are formed on left and right operation portions 7a, 7b. This can prevent user's fingertips from reaching the opposing inner surfaces (10a, 10b) by setting the user's fingertips inserted into finger placing holes (6a, 6b) along upper and lower surfaces of the finger pinch prevention guards 20a, 20b. Consequently, when the operation portions 7a, 7b are in the closed position, the fingertips are prevented from being pinched between the opposing inner surfaces 10a, 10b so as not to cause finger pinch.
