IPC: H05K3/06
Filed: 1988-01-08
Abstract: PURPOSE:To decrease the number of processes by using a base substrate in which a coating film is stuck onto a copper foil, cutting the coating film and forming a pattern through etching. CONSTITUTION:A copper foil section 13 is shaped onto a substrate section 12 while a coating film 14 is stuck onto the copper foil section 13. When a printed board is manufactured from the base substrate 11, a pattern protocol is prepared, information for cutting is prepared, and the coatlng film 14 on the copper foil 13 is cut by an automatic drawing instrument on the basis of the information for cutting. The unnecessary section of the coating film 14 after the completion of cutting is peeled, and the printed board 15 is prepared through etching.

Title: Impregnated cathode body structure
Inventor: NIKAIDO MASARU
IPC: H01J1/28
Filed: 1985-01-11
Abstract: PURPOSE:To almost eliminate the fluctuation of the content of electron emissive material and thereby to improve reliability by forming a hole-sealing layer in the predetermined thickness on the back face of an impregnated cathode body by mechanical working or PVD method and thereafter interposing a soldering material layer. CONSTITUTION:A hole-sealing layer 16 is formed in the predetermined thickness on the back face of a porous impregnated cathode body 11. Said hole-sealing layer 16 plugs a hole part 11b at the opposite side face of the electron emissive face of the cathode body 11 and thereby prevents electron emissive material from diffusing to the back face. And a layer composed of soldering material 15 is interposed between the sealing layer 16 and filler 14 including a heater 13 therein. Next, the sleeve 12 of the outer side of a case filled with the filler 14 is fixed at the periphery of the cathode body 11. Thus, the layer of the soldering material 15 eliminates the fluctuation of the content of the electron emissive material and at the same time, improves the reliability of the cathode body 11.

Filed: 1979-01-17
Abstract: PURPOSE: To adjust the scraping resistance of buckets to scrape precipitated sand under the best condition by moving an underwater head chain wheel by a constant- speed accelerator and providing a mechanism for tensing the chain in response to the movement of the underwater head chain wheel.  
     CONSTITUTION: When a predetermined pressure is applied through a relief valve 20 from a pump 11 to a cylinder 10, the underwater head chain wheel 5 is press- fitted to the precipitated sand deposit, and buckets 7 bite into precipitated sand. When the precipitated sand scraping resistance of the buckets 7 increases, the tension of the chain becomes greater than a predetermined pressure, and the underwater head chain wheel 5 is pulled between a driving chain wheel 3 and an underwater tail chain wheel 6, thus the buckets 7 being separated from precipitated sand. A tensed chain wheel 4 and a cylinder 13 follow up the reciprocating movement of the underwater head chain wheel 5 and tension-operate a chain 8. For this reason, the hydraulic pressure of the pump 11 is reduced beforehand by a reduction valve 18.
