摘要:
A signal processing device detects information drop-out parts of an incoming information signal by dividing the information signal received for a given period of time into an n number (n: an integer which is at least 2) of blocks and by forming an information drop-out part signal indicating a part that has an information drop-out within each of the blocks. The device is thus arranged to be capable of promptly finding the parts of the information signal having information drop-outs.

A recording and/or reproducing apparatus includes a plurality of time base changing elements arranged to perform band compression and expansion by altering the time base of an incoming signal; a switching circuit arranged to selectively change audio signals inputted into and outputted from these time base changing elements from one over to another; and a recording-and-reproducing circuit arranged to record and reproduce the band compressed audio signal on and from a recording medium.

Provided is a glass composition for protecting a semiconductor junction which contains at least SiO2, B2O3, Al2O3, ZnO and at least two oxides of alkaline earth metals selected from a group consisting of CaO, MgO and BaO, and substantially contains none of Pb, As, Sb, Li, Na and K, wherein an average linear expansion coefficient within a temperature range of 50° C. to 550° C. falls within a range of 3.33×10−6 to 4.13×10−6. A semiconductor device having high breakdown strength can be manufactured using such a glass material containing no lead in the same manner as a conventional case where “a glass material containing lead silicate as a main component” is used.

A rotary connector includes a case, a cover, a rotor having a top panel part and a first cylindrical part, a rotor snap having locking parts locked with an outer surface of the cover and a second cylindrical part snap-fitted to the first cylindrical part, flexible cables wound windably/rewindably in the case, and a ring-shaped plate part. In this case, a holding projection project outward in a radial direction from the outer circumferential surface of the second cylindrical part between a lower end of the first cylindrical part and the locking parts, and an inner rim of the cover is provided with a holding step so as to form a step. Furthermore, a wall surface forming the step of the holding step faces side surface of the holding projection, and an inner rim of the cover is rotatably interposed between lower surface of the holding projection and an upper surface of the ring-shaped plate part.

A motor-driven power steering apparatus includes a motor for generating assisting force to be imparted to a steering mechanism, a control signal generation section for generating a motor control signal on the basis of at least steering torque applied to a steering wheel, a motor drive unit for driving the motor in accordance with the motor control signal, and a step-up circuit provided between a battery to the motor drive unit. The step-up circuit includes a step-up coil whose one end is connected to the battery, a first switching element connected between the other end of the step-up coil and the ground, a second switching element connected between the other end of the step-up coil and an output terminal, and a capacitor connected between the output terminal and the ground and smoothing output voltage appearing at the output terminal. The apparatus further includes a step-up circuit control unit which detects the output voltage and controls the first and second switching elements on the basis of difference between a target output voltage and the detected output voltage. During power generation periods, at least the first switching element is turned on and off in order to increase the output voltage supplied to the motor through step-up operation. During regeneration periods, at least the second switching element is turned on and off.

A fluorescent lamp operating apparatus comprises a power switching element electrically connected to a fluorescent lamp having a pair of electrodes, and means for limiting the current flowing through the power switching element by controlling its conductance so as to prevent the power switching element from being broken by a large current flowing from the power line through the fluorescent lamp when the impedance between the pair electrodes decreases from infinity at the start-up of the fluorescent lamp.
