Title: Reproducing device for video signal
Inventor: YOSHINAKA TADAAKI
IPC: H04N5/93
Filed: 1982-08-26
Abstract: PURPOSE:To eliminate the generation of a guide noise band, by extracting a reproduction output when a tape is run at a different speed from that during recording and its delay output selectively, and compensating the reproduction output. CONSTITUTION:Heads 1A-1D reproduce signals Sfa and Sfb, field by field, from tracks alternately and signals Sa and Sc, and Se and Sf are generated from those signals. A switch circuit 28 selects the signals SC and Se alternately at every horizontal period to extract a signal Sd. In this case, the signals Sfa and Sfb are supplied to a detecting circuit 29 to detect the guide band noise, and since there is constant time difference between the guard-band-noise period of the signals Sfa and Sfb and that of the signals Sc and Se, its detection output is supplied as a control signal to the circuit 28 to select the signals Sf and Sa instead while guard band noises are generated in the signals Sc and Se, leading the signal Sd out of the circuit 28. This signal Sd has a guard band noise compensated by the signals Sa and Sf and the line number increases monotonously.

Title: Nonaqueous electrolyte battery
Inventor: TANAHASHI TAKAYUKI
IPC: H01M4/50
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To suppress the rise of the internal pressure and keep a high battery capacity even in the storage of a battery progressed in discharge or in the long-time use with low-rate discharge by using manganese dioxide having a specified ratio of boron mixed thereto and baked at a specified temperature as the manganese dioxide mainly contained in a positive electrode constituting a battery together with a negative electrode lithium or its alloy and a nonaqueous electrolyte. SOLUTION: Manganese dioxide mainly constituting a positive electrode material is obtained by baking a mixture with 0.1-1.0 wt.% of boron at 350-450 deg.C. Instead of boron, aluminum may be added. The trivalent manganese is reacted with the nonaqueous electrolyte and partially dissolved as divalent manganese, and the lithium oxide film formed, when reduced in a negative electrode, arrests the movement of lithium ion and raises the impedance of the battery. Since the ion of the added boron or aluminum is solvated more preferentially than manganese ion, elution of manganese is suppressed, so that no compound of the added element is generated.
