Patent JP-S63151820-A (JP)
Title: Rotor meter
Inventor: YAMAGISHI TOSHIO
IPC: G01F1/22
Filed: 1986-12-16
Abstract: PURPOSE:To attain the safe operation of an apparatus by preventing the generation of trouble when a liquid involves gas, by providing a float stopper composed of an electromagnet or permanent magnet to the upper part of a taper pipe. CONSTITUTION:When a liquid during feed involves gas such as air, a rotor 1-1 violently bounds up and reaches an upper frame body 4-4. At this time, the rotor 1-1 made of a ferromagnetic material is attracted to the magnet 5-5 (float stopper) mounted to the upper frame body part. That is, the upper surface of the rotor 1-1 and the lower surface of the frame body 4-4 are brought into a close contact state to become such a state that a valve is hermetically closed and the feed of the liquid on and after is stopped. At this time, when the attraction force of the magnet 5-5 is weaker than the tensile force due to the gravity of the rotor 1-1, the rotor 1-1 falls and, therefore, the attraction force of the magnet 5-5 is preset so as to be slightly larger than the tensile force of the rotor 1-1. Next, since normal use is impossible in such a state that the rotor 1-1 is attracted, the rotor 1-1 is pushed down by a float thrusting down rod 6-6 to return the rotor 1-1 to normal operation.

Title: Tv receiver
Inventor: TAMURA MANABU
IPC: H04N5/60
Filed: 1988-11-29
Abstract: PURPOSE:To keep a level of an audio output constant by varying the amplification factor of an audio amplifier section depending on a level of an output signal from an FM detection section to be monitored. CONSTITUTION:An audio signal in a received TV signal is extracted from an FM detection section 1, amplified by an audio amplifier section 2 and the result is fed to a speaker 3. On the other hand, an audio signal from the detection section 1 is fed to a level monitor section 4 and monitored. The monitor section 4 gives an amplification signal in response to the level change of the audio signal to the amplifier section 2 to vary the amplification factor of the amplifier section 2 properly. Thus, even when the content of a normal program is broadcast, or even when the content of CM is broadcast, the final level of the audio output from the speaker 3 is kept constant.

Title: Trial-and-error method for correction of error burst and correction method of multibyte error
Inventor: JIYON SUKOTSUTO ETSUGENBAAGAA
IPC: H04L1/00
Filed: 1992-11-10
Abstract: PURPOSE: To reduce the correction time and to minimize the error probability by determing a burst error position employing a reduced trial and error technology which drastically limits the number of latent error positions that are tested. CONSTITUTION: The test against the subblock, which is incorrigible by an ECC, is limited by a first level. Then, the number of bytes, which are continuous and corrigible in an error burst, is limited to the number of bytes in a parity cell so that a parity cell syndrome analysis is made possible. By the analysis. the possible error burst position in a correction incorrigible subblock is identified. Then, the data are corrected at a respective burst position by a temporary trial and error and the correction is inspected by a CRC. When one trial correction and one trial correction only are verified as a success by the CRC, the burst error correction is accepted as an effective one.
