    摘要： In one surface of a semiconductor substrate, an n− layer, a p base layer, a p well layer, another p well layer, a channel stopper layer, an emitter electrode, a guard ring electrode, and a channel stopper electrode for example are formed. In the other surface of the semiconductor substrate, an n+ buffer layer, a p+ collector layer, and a collector electrode are formed. In a curved corner of the p well layer, a p low-concentration layer having a lower impurity concentration than the impurity concentration of the p well layer is formed from the surface to a predetermined depth.

    摘要： A semiconductor includes an N-type impurity region provided in a substrate. A P-type RESURF layer is provided at a top face of the substrate in the N-type impurity region. A P-well has an impurity concentration higher than that of the P-type RESURF layer, and makes contact with the P-type RESURF layer at the top face of the substrate in the N-type impurity region. A first high-voltage-side plate is electrically connected to the N-type impurity region, and a low-voltage-side plate is electrically connected to a P-type impurity region. A lower field plate is capable of generating a lower capacitive coupling with the substrate. An upper field plate is located at a position farther from the substrate than the lower field plate, and is capable of generating an upper capacitive coupling with the lower field plate whose capacitance is greater than the capacitance of the lower capacitive coupling.

    摘要： A ferrule holder and a coil spring are provided in a main body formed in an approximately tube shape. A cable adaptor including a front opening part at a large diameter part is inserted from a back opening part into the main body having slits and. A first small diameter part of the main body fits with the large diameter part of the cable adaptor and prevents the cable adaptor from translating in the z-axis direction. And the second small diameter part of the main body controls transfer of the ferrule holder in the z-axis direction. At the forward part of the large diameter, a taper part which helps to insert the cable adaptor is formed around the circuit of the optical axis. Each slit formed at the back opening part also helps to insert the cable adaptor.

    摘要： A screwing part 1220 is inserted into a large through-hole 1110 from its front side and is screwed together with a male screw part of a jig. A convex part 1230 in an approximately ring shape is formed at a back end part of the screwing part 1220. The convex part 1230 is adjacent to a fitting part 1111 which is made of an approximately ring convex part projecting toward inside of the large through-hole 1110. The back of the fitting part 1111 is adjacent to a front end opening part 1310 of a back tubular part 1300. In short, the fitting part 1111 of the adaptor main body 1110 is sandwiched between the convex part 1230 and the front end opening part 1310. By inserting and pressing the back end opening part 1210 of the front tubular part 1200 into the front end opening part 1310 of the back tubular part 1300, the front tubular part 1200 and the back tubular part 1300 are connected and fixed with each other. Sign β represents their pressing part.
