Title: Ultrasonic treatment probe
Inventor: OGASAWARA TADAHIKO
IPC: A61B17/22
Filed: 1987-05-15
Abstract: PURPOSE:To treat the calculus in the body cavity within a short time, by finishing the leading end part of an insert part into a rough-surface state. CONSTITUTION:A horn 10 has a conical shape and a metal pipe 14 constituting an insert part 3 is connected to the leading end thereof. A suction hole 15 is formed inside the pipe 14 and communicates with the piercing hole 16 formed to the axis parts of both of the horn 10 and a front metal block 8. This piercing hole 16 communicates with the piercing hole 11 of a bolt 12 and the suction passage 17 of an ultrasonic treatment probe 1 is formed by all of the piercing holes. The outer periphery of the leading end part of the pipe 14 is finished into a rough surface 18. Since a large broken piece generated by crushing can be removed out of the body in the state spit on the leading end part of the insert part 3 by finishing the leading end part of the insert 3, it is unnecessary to finely divide the large broken piece and, as a result, a treatment time can be shortened.

IPC: H02M3/28
Filed: 1994-05-31
Abstract: PURPOSE:To obtain a current transformer in which the mounting space can be made smaller, and the contact resistance in a soldering connection part is low. CONSTITUTION:A coil 11 with a magnetic core is inserted into a source terminal 4 of an FET 3, forming a current transformer 21. When the current flowing at the terminal 4 is changed, a current is generated in a winding wire 13 through a magnetic core 12. Thus, the current flowing in the FET 3 can be detected. Therefore, the terminal 4 is used commonly for a primary winding wire of the transformer 21. As the result, terminals 14 and 15 on secondary side are just connected for completion. In addition, the coil 11 is arranged three- dimensinally at the terminal 4, thereby making the mounting space to be smaller.

IPC: H01L21/66
Filed: 1993-05-21
Abstract: PURPOSE:To enable the carrier concentration of a Si dope GaAs single crystal wafer to be measured nondestructively and optically by measuring the luminous intensity of two peaks through optical measurement using photo-luminescence and obtaining the carrier concentration from that intensity ratio. CONSTITUTION:A region where the carrier concentration of a Si dope GaAs single crystal wafer is to be measured is irradiated with excitation light of a wavelength having energy in excess of the band gap of a GaAs semiconductor, and the luminous intensity of the resultant two peaks of a photo- luminescence(PL) spectrum is measured. Under the ambient condition of two PL spectrum peaks being in the vicinity of 77K, the luminous spectrum is the one which belongs to an impurity Si giving rise to the luminous peak in the vicinity of 1.45eV and the luminous peak in the vicinity of 1.18eV. This enables a PL measurement to be made in regard to any Si dope GaAs wafer in terms of correlation between a PL peak intensity ratio b/a and the carrier concentration, and the carrier concentration can be obtained from the PL peak intensity ratio b/a.

Abstract: PURPOSE:To eliminate a transient response and thereby to enable stable detection of an edge by detecting the edge on the basis of a signal of deviation between an edge signal of a web and the like and a delayed edge signal obtained after the edge signal is delayed. CONSTITUTION:A laser light of a laser generator 5 is applied to a web 1 and reflected by a concave mirror 2, part of the light transmitted through the web 1 is made to enter an optical sensor 6 such as a photodiode, and the quantity thereof is thereby detected. While a raw signal A is inputted directly to a comparator 10, on the occasion, the raw signal A is delayed for a prescribed time by a delay circuit 20 and thereafter a delay signal B is given to the comparator 10. A difference between the two signals A and B is taken up by the comparator 10, a difference signal C thus obtained is compared with a threshold level, and an edge signal is outputted when the signal C exceeds the level. Therefore an overshoot resulting from a transient response can be eliminated, and also the effect of the density or quality of the web can be removed substantially.
