IPC: G01N29/28
Filed: 1983-12-19
Abstract: PURPOSE:To enable the good observation of a specimen, by providing a container having a liquid metal held therein to the leading end part of an acoustic wave lens. CONSTITUTION:A holding part 14 is provided to the leading end part of a spherical lens 1 and a cylindrical hole having a diameter same to or slightly larger than that of a recessed hole possessed by the lens 1 is provided to the central part of said lens 1. When a liquid metal 15 as a medium is inserted into said hole in the almost same amount as a sphere formed along the radius of curvature of the recessed hole, the liquid metal 15 is contacted with the holding part 14 and the lens 1 and held. In this case, because a part of the leading end part of said lens 1 is contacted with a specimen 17 and an acoustic wave can be propagated to the specimen 7. Because the sphere of the liquid metal 17 is held from the periphery thereof by the holding part 14, it is not scattered even by shock from the outside and stable operation can be operated and the good observation of the specimen is enabled.

IPC: H03H11/32
Filed: 1987-09-22
Abstract: PURPOSE:To set an impedance conversion ratio freely with low loss even with a conventional transformer employed and even with an operating frequency increased by using the impedance conversion ratio to form both a voltage waveform and a current waveform given to the transformer into nearly sinusoidal waves. CONSTITUTION:An impedance conversion circuit 141 consisting of a coil L1 and a capacitor C1 of a matching circuit 14 is connected to a balanced output end of a class D bridge power amplifier circuit 11, impedance conversion is applied by the conversion circuit 141 and the converted output is given to the primary winding of a transformer 142. Then one terminal of the secondary winding of the transformer 142 is connected to the input end of an unbalanced load circuit 13, the other terminal is connected to the ground and the transformer 142 applies balanced/unbalanced conversion. When a square wave voltage is applied to the input of the matching circuit 14, the current flowing to the impedance conversion circuit 141 is a sinusoidal wave comprising nearly the fundamental wave only. Thus, both the voltage and current fed to the primary winding of the transformer 142 are formed almost by fundamental waves only and almost no power loss is caused in the transformer 142.

Filed: 1992-09-07
Abstract: PURPOSE: To increase the voltage loop band width, and to obtain a high speed and exact dynamic response by continuously monitoring load current and load voltage, and executing control through two different feedback loops with an adder. CONSTITUTION: When an input voltage Vin from a power source 120 is applied, a current sensor and feedback loop 140 outputs a voltage Vi in direct proportion to currents pulled by a load 110 to an adder 130. Also, a voltage in direct proportion to a difference between a voltage Vout and a fixed reference voltage is inputted from a voltage sensor and feedback loop 150 to the adder 130. The adder 130 gates a path device 160, and generates a resistance almost in inverse proportion to a voltage impressed to a gate. As a result, when either or both the current feedback input and the voltage feedback input to the adder 130 are increased, the voltage from the adder 130 is increased, the resistance through the path device 160 is decreased, currents are increased, and the Vout is held in a desired level.

IPC: B24B21/00
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To improve finishing conditions by providing a locus operation means which performs acceleration/deceleration operation after distributing the pulses to respective shafts to operate smoothly without stopping according to unsmooth shapes obtained from the outside program of working locus. SOLUTION: A shape error is compensated by connecting across correction vectors of tool diameter correction blocks B1, B2, which have different correction quantities and positioned in the front and the rear each other, by a linear block, and by using a tool diameter correction mechanism which can change the correction quantity according to a tool diameter correction block in a working cycle. Namely, when the lengths of the correction vectors V1, V2 are different, a different level part is connected by a linear vector V3, a collinear line of the correction vectors V1, V2. The shape which is obtained by an outside program of a formed working locus and is not always a smooth shape is smoothly corrected by pulse distribution to respective shafts and acceleration/ deceleration operation afterward.
