IPC: B08B9/34
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To prevent a great amount loss of jet water while a label is efficiently thoroughly peeled off in a short time by a method wherein high pressure water is jetted with a swing nozzle swinging vertically or left and right to the stuck label. SOLUTION: A conveyor 11 carries automatically a label sticking case 10. A swing nozzle 1 jets high pressure water swinging vertically in a stuck paper- made label 10a at right angles to a label advancing direction.

Patent JP-S60160709-A (JP)
Title: Differential amplifier
Inventor: KUMANO MASAHIRO
IPC: H03F3/34
Filed: 1984-01-31
Abstract: PURPOSE:To obtain an output having an excellent frequency characteristic and a large dynamic range by connecting each current line of transistors (TR) of a differential pair in a way of addition/subtraction and connecting a constant current source and an output TR to the connecting point. CONSTITUTION:When a positive voltage is impressed to an input terminal (d), a current of a TR18 is increased and a current of a TR14 is decreased. The current flowing to the TR14 becomes a collector current of a TR21 via TRs 15, 16, 17 and 21 constituting a current mirror. Moreover, the current flowing to the TR18 is applied with current mirror operation by TRs 19, 20 and the result becomes a collector current of a TR20. Thus, the difference between the collector currents of the TRs 20, 21, that is, the current twice the current change component flows to a TR25. This is because the current value of the constant current source 26 is constant at the emitter of the TR25. The output signal is converted by a load resistor 27 and extracted from an output terminal 30 via a TR28.
