    摘要: A magneto-optical recording apparatus capable of maintaining decoding performance even if the recording density at the magneto-optical recording is high. The magneto-optical recording apparatus comprises a modulator for RLL (Run-Length Limited) encoding recording data, an NRZI encoder for NRZI-encoding a RLL code from the modulator, an equalizer for equalizing a read-out analog signal obtained from a magneto-optical recording medium into a waveform (1+D).sup.n (n is a positive integer) assuming that the delay time for one bit period of the read-out signal is D, a low pass filter, and a Viterbi decoder that uses the difference between a sample value obtained by quantizing an output from the low pass filter and an expected value obtained from a theoretical value of a data column to make the most probable path to be decoding data.

    摘要: The present invention relates to an full-arc admission steam turbine having its output controlled by regulating the opening of a steam regulating valve. The full-arc admission steam turbine is run at a higher efficiency than that of the full-arc admission steam turbine of the prior art by improving the drop in the internal efficiency of the turbine due to the throttle loss of the valve. Moreover, a substantially constant high efficiency is maintained for the time period from the designed point of a partial load to the rated load if the second blade stage group is selected to provide an internal efficiency substantially equal to that of the blade stage group of the prior art.

    摘要: A brake booster, in particular, a construction for strengthening the coupling between the brake booster and a master cylinder, is disclosed. The head of a bolt which extends through an enclosed shell is welded to the internal surface of the shell so as to maintain a hermetic seal, and a strengthening plate disposed around the bolt head is welded to the internal surface of the shell. Additionally, a reinforcing member fixedly connected to the strengthening plate is welded to the bolt head to improve the rigidity of the strengthening plate.

    摘要: A vacuum power servo booster including a disc-shaped inner shell and a cup-shaped outer shell with a diaphragm secured between the two shells. A radially opening annular groove is formed in peripheral portions of the inner shell by a first annularly bent portion bulging radially inwardly and a second annularly bent portion oriented along the axial direction of the booster. The outer shell includes rectangular recesses into which extend inwardly at the open faces.
