Title: Apparatus for measuring thickness of clad
Inventor: NAKANO TETSUO
IPC: G01B17/02
Filed: 1991-02-25
Abstract: PURPOSE:To enhance the measuring accuracy for the thickness of a clad and to shorten the measuring time by providing a full-thickness-echo receiving amplifier, a clad-echo receiving amplifier, a gate means, a zero-cross detecting means, a clad-thickness computing means and the like. CONSTITUTION:A full-thickness-echo receiving amplifier 5a and a clad-echo receiving amplifier 5b are connected to a receiving-side piezoelectric transducer 3b. The amplifiers 5a and 5b are adjusted to the different amplitudes corresponding to the respective levels of a full-thickness echo B and a clad echo C. The output signal of the amplifier 5a is sent into a B-gate selector 11 and a B-zero- cross detecting circuit 13. The output of the amplifier 5b is sent into a C-gate selector 14, and C-zero-cross detecting circuit 15. A clad-operating part 20 operates the difference between the first counted value until the zero-cross point of the full-thickness echo B is detected and the second counted value until the zero-cross point of the full-width amplified signal of the clad echo C and sends the difference into a sound-speed operating part 21. The operating part 21 obtains the thickness of a clad material 2 based on the difference between the first counted value and the second counted value which is sent from the operating part 21 and the sound speed of the clad material 2.

IPC: B41J2/385
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To suppress heat generation by a driver current by selecting between power supplies for supplying a first pulse potential which allows passage of an image visualizing particle through the gate of a control electrode and a second pulse potential which does not allow the passage, and supplying the first pulse potential to a switching means at least, through a resistance element. SOLUTION: A control power supply part consists of a first power supply 85 which supplies a potential allowing passage of a toner through a gate to a band-like electrode, a second power supply 84 which supplies a potential not allowing the passage, a resistance 83, an FET 88 as a potential switching means, an image signal control circuit 86 and an FET 89 as a pulse generating means. In this case, the time for supplying the potential not allowing passage of the toner through the gate is longer than the time for supplying the potential allowing the passage, and almost all the potential applied is the potential now allowing the passage. In addition, a power supply 95 is applied to an FET 94 through a resistance 93, and to electric current runs through the FET when the potential now allowing the passage is applied.  Thus it is possible to avoid the non-conformity relative to heat generation and power consumption.
