Title: Ballast mounting structure for discharge lamp apparatus
Inventor: IKEDA TAKAMASA
IPC: H01F37/00
Filed: 1987-07-27
Abstract: PURPOSE:To improve the radiation property of a ballast and lower noise as well, by fixing a narrow width part of an elastic supporting plate having a broad width part which covers the whole base plane of the ballast to a mainframe of the title apparatus, thereby fixing the broad width part to the ballast. CONSTITUTION:Two pieces of straight pipe fluorescent lamps are fixed to lamp sockets of the mainframe 2 of this apparatus. Each elastic supporting plate 6 is formed at the mainframe 2 by providing slittings 5 around the mounting part of a ballast 4. As the elastic supporting plate 6 having a broad width part 6a which almost covers the whole base plane of the ballast 4 is installed, the apparatus may have a large effective radiation area of the ballast 6 and makes temperature increase of the ballast 6 small. As the base plane of the ballast 4 is almost covered by the broad width part 6a of the elastic supporting plate 6, no gaps are formed between the ballast 4 and the mainframe 2 of the apparatus and oscillations due to the leakage of magnetic flux can be avoided. Thus the apparatus prevents a noise.

Abstract: PURPOSE:To obtain a spacer ring of high quality having highly accurate parallelism and flatness with low cost by applying the prescribed working and processing to an extrusion (pull-out) tube of an Al alloy which has the prescribed length and can produce plural products and obtaining plural spacer rings. CONSTITUTION:A long extrusion or pull-out tube of an Al alloy from which the internal stress is previously deleted is cut in the prescribed length for production of plural spacer rings.

These holes are successively drilled with shift of the positions to be drilled. Both inner and outer circumferential surfaces of such a source tube are ground and the fats and oils are deleted. Then a chemical polishing or etching process is applied, and V-shaped circulator grooves 30a are cut with prescribed intervals by an NC lathe. Then plural spacer rings are produced by a cutting process. The end surfaces of spacer rings are finished. Thus it is possible to obtain a spacer ring of high quality having highly accurate parallel and flat degrees.

Title: Reproducing device of magnetic video signal
Inventor: YAMAMOTO MOROHISA
IPC: H04N9/84
Filed: 1982-10-29
Abstract: PURPOSE:To prevent the generation of a flicker phenomenon due to skew distortion by compensating the pulse width varied by the skew distortion. CONSTITUTION:If the 4th pulse of a horizontal synchronizing signal appears faster by the skew distortion, an edge pulse generating circuit 35 generates an edge pulse P5 to reset a pulse generating circuit 31 at the switching of a channel. Consequently, the pulse width t1 of a pulse P3 is synchronized with a pulse P5 and turned to an L level and the pulse width t1 is turned to t1''. Since a pulse P1 resets also a counter 32, no counted output is obtained from the counter 32. On the other hand, the pulse generating circuit 31 is actuated again by the 4th pulse of a horizontal synchronizing signal and the H level part with the time width t1 corresponding to the 4 pulses of the horizontal synchronizing signal appears in the pulse P3 again. Therefore, an upper flicker due to the skew distortion does not appear in a reproduced picture.

A series of recessed parts 40D is formed at a specified arraying pitch angle along the peripheral direction on the inside surface of the ring 40 and a pin element 46 is held on the focusing ring side.  When the ring 40 is at the MF position, the pin element is engaged in optional one of the series of the recessed parts.
