Title: Cable laying pipe, and its connecting structure
Inventor: SHIBATA TETSUYASU
IPC: F16L9/19
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To keep inserted cable or others safe, by placing cutout recessed grooves, through which communicating cables or others can pass, on a surface of the outer peripheral wall of a hollow pipe, and by providing a lid on an opening part of the cutout recessed groove. SOLUTION: Three cutout recessed grooves 6, through which communicating cables 4 or propulsion work piping hoses 5 can pass, are drilled axially in parallel with a given interval on the outer peripheral wall surface of a thick wall part 3a of a cable laying pipe 1. A lid 13 is attached to the opening edge of the cutout recessed grooves 6 via a supporting shaft 13a such that the lid 13 can be opened or closed. As a result, only insertion of the communicating cables 4 or the propulsion work piping hoses 5 into the cutout recessed grooves 6 can facilitate insertion work. Because the lid 13 prevents the cutout recessed grooves 6 from being exposed during propulsion of the cable laying pipe 1, the communicating cables 4 or the propulsion work piping hoses 5 can be kept safe.  In addition, because no recessed part is formed, coefficient of friction is low and propulsion can be smoothly performed when a propulsion method is employed and construction is performed.

Title: Clamping circuit
Inventor: OKADA TAKAFUMI
IPC: H04N5/16
Filed: 1977-12-22
Abstract: PURPOSE: To obtain a clamping circuit which features the current operation suited to formation of the semiconductor integrated circuit.  
     CONSTITUTION: With supply of video signal A to input terminal 1, the level of current IS is decided by constant current source 7. When the current level is less than prescribed clamping current IR, Tr6 is off and the same current as signal current IS flows to Tr5, 4 and 10 to be obtained at output terminal 11. When current IS becomes over the level of current IR, the current flowing to Tr4 becomes insufficient with only current IR supplied from current source 7. As a result, Tr8 and 6 are turned on, and the collector current of Tr4 is reduced. In other words, the base negative feedback circuit of Tr8→Tr6→Tr4 is formed with increase of IS more than IR, the collector current of Tr4 turns to clamping currnet TR which decides the tip of the synchronous signal of the video signal, and the current flowing to Tr4 is obtained drectly at terminal 11. Thus, the video signal is obtained with the tip of th synchronous signal is clamped like B.
