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.

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 bioactive material is obtained by heating pearl. A calcium component and conchiolin, which is contained in pearl, are activated by heating. Said bioactive material is useful as a plant growth agent, an animal growth agent, a fish growth agent, a medicine, a preservative, and the like.
摘要:
An image is formed in a photographic element by a process comprising a step of heating a heat-developable photosensitive material in the presence of a specific compound which typically releases a phenylmercaptotetrazole having a substituted benzene ring and serving as a development retarder.
摘要:
A heat-developable light-sensitive material is described, comprising a support having provided thereon at least(a) a binder;(b) a light-sensitive silver halide;(c) at least one silver salt of a compound represented by formula (I) or (II) ##STR1## wherein Z represents a non-metallic atomic group forming a heterocyclic ring together with the nitrogen atom,A--C.tbd.C--H (II) wherein A represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;(d) a silver salt of a compound represented by formula (III)B--S--H (III) wherein B represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group; and(e) a reducing agent.The material exhibits stable developability despite variations in development temperature or time, and provides an image having high maximum density and low minimum density.
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.
