    摘要: In an LDMOS, an n-type region 6, which is formed to have a concentration higher than that of an n-type substrate 1 and whose concentration gradually increases from the n-type substrate 1 to an n+ type drain region 5, is disposed so as to surround the n+-type drain region 5. Further, a p+-type contact region 9 disposed adjacent to an n+-type source region 8 is formed so as to extend below the n+-type source region 8 so that a parasitic transistor formed by the n+-type source region 8, a p-type base region 7 and the n-type substrate 1 is hardly turned ON.

    摘要: An apparatus for testing integrity of a printed circuit board is provided which employs a probe with moveable and/or fixed needle portions at its ends and a flange, probe retention boards having apertures for sliding the probe through, an interface board disposed parallel to the probe retention boards. The flange is disposed between the retention boards and the interface board. The needle portion provided away from the interface board comes in contact with the printed circuit board for testing. No socket is used in the apertures for accommodating the probe in the apertures. An assembly kit including these parts are provided for assembly by a user.

    摘要: A transistor causes a current to flow through a heat generating resistor in response to a picture signal and simultaneously, a capacitor coupled to the transistor is charged. When a charged voltage on the capacitor reaches a predetermined magnitude, the transistor stops the current to prevent the resistor from exceeding a predetermined magnitude and the capacitor begins to discharge. A plurality of resistors mentioned above are disposed in a row to form a thermally sensitive head which records a picture image on thermally sensitive paper as determined by the respective picture signals.
