Title: Drawing method
Inventor: OKA KIYOSHI
IPC: B21C1/00
Filed: 1993-04-12
Abstract: PURPOSE:To produce a steel wire having a stable quality with a smaller labor power by successively drawing a wire rod with a drawing die through pinch rollers after forming a borax coating film. CONSTITUTION:The surface ruggedness of a hot rolled wire rod 1 which is mechanically descaled is uniformly adjusted and the borax coating film is formed. After that, an electric signal that is detected with a piezoelectric element 14 which is attached on the drawing die 13 is measured by separating the frequency of <=300kHz from the frequency of >=300kHz by a signal processor while drawing the wire rod with the drawing die 13 and outputted by contrasting them with a signal in the stable state. Then, after forming the borax coating film, successively the wire rod is drawn by the drawing die 13 through the pinch rollers 12 which are mounted on the inlet side of a die box 11 of a wire drawing mill within 20sec as continuously blowing warm wind. In this way, trouble such as die wear, disconnection, are prevented.

Title: Manufacture of cathode-ray tube
Inventor: KONUMA KAZUO
IPC: H01J9/39
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To improve an electron emission characteristic through purifying a cathode, by emitting an electron from the cathode in a period where gas is emitted due to heating a getter device. SOLUTION: A degree of vacuum for heating a getter device is 1×10<-6> Torr or less, and various gases exist in a tube body in the first half in a gas emitting mode of gas, emitted from a getter T directly after getter heating. An electron is emitted from a cathode cone when the partial pressure of a gas component other than argon and helium becomes 1×10<-8> Torr or less, and argon partial pressure becomes 1×10<-8> or more and 1×10<-6> or less. Electron emission is finished in one or two min. and then vacuum drawing is continued to perform sealing in a condition where the argon partial pressure is 1×10<-8> Torr or less. After sealing, the partial pressure in a residual gas, an active gas in particular, is reduced by the pump action of the getter device.  A CRT can be driven in a condition where the residual gas partial pressure of gas other than argon and helium is 5×10<-9> Torr or less.

Title: Assorting system
Inventor: JONES KEITH MALCOLM
IPC: B07C3/08
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an assorting system in which group objects having no allocated carry-out containers are temporarily stored in a system until a quantity to make assorting processing more efficient is attained by determining whether the carry-out containers are allocated thereto or are recycled when these group objects approach an ejection apparatus. SOLUTION: The essence of the system lies in that postal item groups more than the existing carry-out containers 12 may be handled. Not all the postal item groups have the allocated carry-out containers 12. This allocation may be achieved by the control system 16 which makes decision in such a manner that the groups are housed into the respective storage containers 4 of a circular conveyor 6 until the quantity sufficient for efficiently gathering and assorting the objects having the common forwarding destinations is attained. When judgment is made that the objects having the same forwarding destinations accumulate sufficiently at the circular conveyor 6, the system executes control in such a manner that the objects are discharged into the carry-out containers 12 when the respective storage containers 4 pass above the related carry-out containers 12.
