摘要： An SR (Selective Repeat) ARQ system with limited buffer memory is realized by modifying a part of a user data area. A transmitter side modifies a part of a user data area in a data frame so that it differs at least one bit from corresponding part of a frame with the same frame number as that of a current frame in a preceding modulo turn, and a receiver side compares said part of a user data area with corresponding part of a frame with the same frame number as that of a current frame in a preceding modulo turn. When they coincide, the receiver side disregards the received frame as it is re-transmitted frame which is already received correctly, and when they do not coincide, the receiver side takes the received frame. Preferably, said part of a user data area is the last word area in a user data area in a frame structure. When a user data has more words than capacity of a user data area in a frame structure, and when last word is completely equal to last word of a frame with the same frame number as that of a current frame in a preceding modulo turn, the last word in a user data area is transferred to a succeeding frame, and an area for that last word is filled with a data which differs at least one bit from a data in the last word in the corresponding frame having the same frame number as that of the current frame in a preceding modulo turn.

摘要： A torque sensor comprising a magnetic amorphous film whose magnetostrictive characteristics vary with the amount of torque applied thereto and coils for detecting magnetostrictive variation disposed opposite the magnetic member. The torque sensor is constituted as an independent unit separate from the shaft whose torque is to be measured. The independent unit comprises a tubular or a shaft member having the magnetic amorphous film attached thereto and a housing with the coils at its inner wall. The housing covers the tubular or shaft member and is rotatable about the same axis as the member. The tubular member is easily mounted on the shaft through spline fittings in one embodiment and the short shaft member of the other embodiment is easily mounted between the two shaft ends via spline fittings and flange couplings.

摘要： A semiconductor device has a semiconductor substrate including a body region, a drift region, a trench that extends from a surface of the semiconductor substrate into the drift region through the body region, and a source region located adjacent to the trench in a range exposed to the surface of the semiconductor substrate, the source region being isolated from the drift region by the body region. A specific layer is disposed on a bottom of the trench, and it has a characteristic of forming a depletion layer at a junction between the specific layer and the drift region. An insulating layer covers an upper surface of the specific layer and a sidewall of the trench. A conductive portion is formed on a part of the side wall of the trench.
