Title: Lock bolt falling preventing metal fitting
Inventor: EGUCHI TAKUMI
IPC: E21D20/00
Filed: 1995-08-14
Abstract: PROBLEM TO BE SOLVED: To surely prevent falling of an expansion type lock bolt. SOLUTION: Prior to the drive of an expansion type lock bolt 7 into a bore hole, the opening part 21 of the cylindrical body 22 of a falling preventing metal fitting 20 is expanded by a tool, and fitted to a sleeve 5 fitted to the tip of the lock bolt 7.

Abstract: PURPOSE:To prevent dewing on a surface cooled by radiation without using a special recovery apparatus by comprising blast adjusting means for supplying part of the radiation means of second heat exchanger means with the air heat- exchanged with a pressure-reduced liquid refrigerant from circulating means. CONSTITUTION:In cooling, a high temperature and high pressure refrigerant from a compressor 2 is cooled to be condensed by an outdoor heat exchanger 4, the pressure is reduced to 17-18 deg.C by a first throttle device 5 and enters a second indoor heat exchanger 8 to be vaporized. At this time, latent heat of vaporization is supplied indoors by radiation from the radiation panel 15 of the second indoor heat exchanger 8 and contributes to cooling a room. Thereafter, the pressure of the refrigerant is reduced to 12-13 deg.C by a second throttle device 9 and vaporized in a first heat exchanger 7. Then, the refrigerant is converted to a low pressure gas and fed to the compressor 2. As described above, since indoor heat exchange at two temperatures can be realized, dewing to the radiation panel 15 can be collected in the first indoor heat exchanger 7 and recovered. Therefore, an increase in the dewing on the panel 15 of the second heat exchanger 8 can be prevented.

Filed: 1987-08-20
Abstract: PURPOSE:To correctly detect a header and to improve transmission efficiency, by performing error inspection after detecting the code of the header, and shifting a reading position in a memory sequentially until the correct result of the error inspection is obtained. CONSTITUTION:When a shift register 3 reads data of one block, a switch 2 is connected to (b) side, then, the output terminal Q of the register 3 is connected to the input terminal of the register. Simultaneously, the data is supplied from the terminal Q of the register 3 to a header detection circuit 5 and a CRC inspection circuit 6 in synchronism with a clock signal. When the header detection circuit 5 detects the same code as that of the header, the circuit 6 is reset, and CRC inspection is started. When an error exists in the result of the CRC inspection, the register 3 shifts again a readout data position by every bit until the circuit 5 finds out the same code as that of the header. In such a way, when the correct result of the CRC inspection is obtained, the data is sent from a multiplexer 8 via a port 9.
