Abstract: An editing system in which a personal computer is easily configured as an editing apparatus that performs editing processing in synchronization with predetermined timing. According to the invention, a personal computer 2 transmits an acquisition command C1 to a timing notice apparatus 4 over a USB cable 3, as a result, the personal computer 2 receives a timing notice signal S2 transmitted from the timing notice apparatus 4 under frame timing over the USB cable 3. Thus, it becomes possible to notify the personal computer 2 of the frame timing as reception timing of the timing notice signal S2 by connecting the timing notice apparatus 4 to the personal computer 2 over the USB cable 3 without the need of troublesome works such as installing a PCI board in a main body of the personal computer 2, thereby realizing an editing system 1 in which the personal computer 2 is easily configured as an editing apparatus that performs editing processing in synchronization with predetermined timing.

Abstract: Temporarily storing audio data to be reproduced in the block form, temporarily storing synthesized audio data in the block form, generating and supplying a reference signal, and calculating the first address of the block of audio data, the editing system of the present invention enables identifying the buffering position of the recording signal and then matching the position to the reproduced signal, resulting in quick editing.

Abstract: A bolt set is provided that is made of steel free from technical difficulties in production, inexpensive in production cost, and improved in fatigue strength by a simple configuration. More particularly, a bolt set made of steel in which a tensile fluctuation stress acts upon an external thread side, characterized by setting a pitch difference ?P(=Pf?Pm) between a pitch Pm of the external thread and a pitch Pf of the internal thread within a range of 0.5-0.8% based on a pitch P prescribed in JIS B 0205 of Japan Industrial Standard.
