IPC: G11B5/588
Filed: 1987-09-10
Abstract: PURPOSE:To attain a reproducing without noises even at the time of a head switching transition, by controlling the displacement of a pair of movable heads in the vertical blanking period of a reproducing signal by another pair of fixed heads. CONSTITUTION:Fixed heads 5B are used when a tape feeding speed is a regular speed and when the tape feeding speed changes against the regular speed, movable heads 5A are used, by corresponding to the tape feeding speed, displacement is controlled in the transverse direction of an oblique track on a tape.

A target in-stroke intake air quantity MGa4 for throttle-opening angle setting is calculated from MGa3, and the control level of the throttle opening angle is set on the basis of MGa4, an actual in-stroke intake air quantity, an intake-air supply rate and an engine-speed index value.

Title: Digital delay detector
Inventor: FUKUDA SHINJI
IPC: H04L27/14
Filed: 1988-09-12
Abstract: PURPOSE:To surely detect a modulation wave by leading out the result of multiplication of outputs of exclusive OR gates when a deviation of phases between an intermediate frequency signal and a retarded intermediate frequency signal is within a predetermined range and leading out the result of multiplication of outputs of data flip-flops when the deviation of phases is at the outside of the said range as a detection output. CONSTITUTION:When a phase deviation DELTAtheta between an intermediate frequency signal fIF from a BPF 37 and a retarded intermediate frequency signal fIFa from a delay circuit 39 is within a predetermined comparatively small range, at the reception of a header part or a preamble part of a data to be sent, an output from an exclusive OR gate 42 is led out as a detection output and an output from a data flip-flop 38 is lead out as the detected output when the deviation is comparatively large. Thus, even in the event of fluctuation such as fluctuation of a transmission frequency or fluctuation of a local oscillation frequency fLO or a reference clock frequency fCL, the sent data is accurately decoded.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To grow a semiconductor crystal with high purity by a method wherein diffusion and segregation of As, Ga, Al and take-in from the atmosphere, and crystallinity of Ge are individually controlled. SOLUTION: First, when substrates are set in a group 10-group V dedicated growing chamber to grow Ge, AlAs being an underlayer is formed. Next, a surface structure is controlled so that AlAs is heated and a group V-group III ratio of a face is set less than about 0.5 not exceeding a (3×2) structure. Next, the surface structure is kept without reducing temperature of this AlAs, while the substrates are carried into a Ge dedicated growing chamber, and Ge is grown on the AlAs. Thereby, the surface structure of the underlayer for growing Ge is the one having a few As, and diffusion and segregation of As into Ge are controlled, and crystallinity of Ge can be enhanced.
