Title: Position detector for cutting edge of tool
Inventor: FUKUHISA NOBUO
IPC: B23Q17/22
Filed: 1984-07-17
Abstract: PURPOSE:To correctly work a workpiece without measuring the workpiece by correctly and easily detecting the position of the edge of a cuttig tool by using a position detector and calculating the feeding amount of the tool from this position. CONSTITUTION:A position detector 12 is installed onto the tail stock or the chuck of a lathe. Then a shank 15 is electrically connected to the lathe body and a cutting tool installed onto the lathe, and also the center shaft coincides with the center shaft of a work. Therefore, when the edge of the cutting tool is attached onto the cylindrical surface 31 of a contact-point member, an electrical circuit consisting of a battery 22 and an LED which are connected in series is closed, and the LED24 comes ON, and the contact between the cutting tool and a contact-point member 18 is detected, and the position of the top edge of the cutting tool can be correctly detected. In other word, the radius R of the cylindrical surface 31 of the contact-point member 18 can be worked with high accuracy, and the contact between the cylindrical surface 31 and the edge of the cutting tool is electrically detected, and the position of the cutting edge is set at the position far by R from the revolution center shaft. Therefore, it is enough to calculate the feeding amount of the tool from this position.

Title: Method of forming metal protruded electrode
Inventor: MATSUMURA KAZUHIKO
IPC: H01L21/60
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To form metal protruded electrodes on a metal electrode of a semiconductor chip or the like with a uniform height and a proper shape. SOLUTION: A semiconductor chip 1 is set in an electrode-forming chamber 7 into which an inert gas 10 can be introduced. This electrode-forming chamber 7 is dipped in a dipping tank 6 containing a low melting point metal 9. The low-melting point metal 9 adheres to a metal electrode 2 by immersing the chamber for about two seconds. An inert gas 10 is injected into the electrode- forming chamber 7 by an air-supplying pipe 8. Consequently, the low melting point metal 9 adhering to the metal electrode 2 is separated from the low melting point metal 9 in the dipping tank 6, and metal protruded electrodes 5 with a uniform height of about 10 μm are formed on the metal electrode 2. Then, the electrode forming chamber 7 is removed from the dipping tank 6, while further injecting the inert gas 10 into the electrode-forming chamber 7.

Title: Travel device in duct line
Inventor: AOSHIMA SHINICHI
IPC: G01N27/82
Filed: 1987-06-17
Abstract: PURPOSE:To simplify a mechanism and miniaturize a device, by providing a travel device with a piezoelectric unit and a shape memory alloy. CONSTITUTION:On the side surface of the piezoelectric bimorph 15 of two piezoelectric elements which are put together, two sets of resistors 14 confronted with each other are arranged. By applying AC voltage to the piezoelectric elements, flexible oscillation is generated on the bimorph 15. By this flexible oscillation, the resistors 14 are oscillated alternately on the left and right in the direction of a duct axis. Then, by applying a shape memory alloy wire 16 to this oscillation, a moving mechanism which can be run in both the left and right directions is considered. In other words, by conducting current to a shape memory alloy A to heat it and by transforming the resistors 14 to remove the tips from a duct line, the mechanism is run in the left direction. By repeating this action, the mechanism is continuously advanced. On the contrary, when current is conducted to a shape memory alloy B, then the mechanism is run in the counter direction by the same action. Accordingly, a wheel or a motor is not used, and so the mechanism is simplified and is easily manufactured and can be miniaturized.

Abstract: PURPOSE:To eliminate the limit of an increase in speed based upon transistor(TR) characteristics by speeding up the discharging of an MOSFET gate capacitor to be driven by a simple circuit without using any TR. CONSTITUTION:A TR 2 is turned on and off with rectangular control pulses and the output of a DC power source 22 are converted by the alternate conduction of FETs 3 and 4 connected to PP form into rectangular driving pulse, which is supplied to the connection point between the FETs 3 and 4.
