Abstract: PURPOSE:To prevent a fitting section from enlargement of a diameter to promote pipe drawing work efficiency and to reduce manpower for cutting the front end of a pipe or excess materials by fitting the rear end of a through-hole head to the front end of a buried pipe, and providing a slipping preventative member. CONSTITUTION:The front end section 1a and the rear end section 1c are provided to a through-hole head 1, and the front end section of a buried pipe 5 is internally fitted to the rear end section 1c and is held to form a pipe drawing device. A slipping preventative member 2 preventing the buried pipe 5 from slipping is provided, and a wire 3 connecting the slipping preventative member to the through-hole head 1 and a tightening screw 4a of the wire 3 are provided.

Title: Digital communication equipment
Inventor: HORI AKIHIRO
IPC: H04J3/06
Filed: 1985-02-22
Abstract: PURPOSE:To realize a high-speed synchronizing restoration circuit with a low- speed logical element by using a parallel processing circuit, providing a frame synchronizing circuit to apply frame synchronization to divided data in parallel and applying data processing in response to the synchronizing information. CONSTITUTION:Data 3, 4 are inputted to a frame synchronizing circuit 210 and DATA 5, 6 are inputted to a frame synchronizing circuit 211 respectively among data 3-6 divided into four by a serial converter 56. The frame synchronizing circuit 210 applies one bit instantaneous shift system to 2 parallel data and the frame synchronizing circuit 211 applies synchronization restoration. Since a frame bit exists in one data among the DATA 3-6, the synchronizing restoration is applied to any of the frame synchronizing circuits 210 and 211 and the other synchronizing circuit is in the hunting state. The synchronization restoring time is doubled but the number of the frame synchronization circuits is decreased. Thus, a low-speed and low-power consumption element is used in place of a high-speed and large-power consuming element.

The compressed air from an air source 26 is thereafter supplied via an air vibrator 24 into the molding space 37 to act the air pressure on the molding sand 41. This air vibrator 24 feeds and discharges the compressed air at prescribed periods by a rotary type air valve 27 to induce the pneumatic vibrations. At this time, the vibrations are acted on the molding sand for a vibration time of 0.3 to 2 seconds at a frequency of 8 to 20Hz and the max. amplitude of 0.1 to 0.6MPa. As a result, the molding sand 41 is fluidized, by which bridges are broken and the sand is settled and packed uniformly. The molding sand 41 is thereafter mechanically compressed by squeezing feet 19.
