Inventor: WATABE EISAKU
IPC: H01L23/50
Filed: 1984-03-26
Abstract: PURPOSE:To improve the reliability of an electronic component part by removing an Al clad before plating external leads to prevent a plated film from separating, thereby preventing the film from readhering to the other portion and removing a cause such as a shortcircuit between lead frames and between wirings of a mounting substrate.

Title: Low distortion amplifier
Inventor: OTOBE KENJI
IPC: H03F1/32
Filed: 1993-02-22
Abstract: PURPOSE:To form a low distortion amplifier circuit without increasing the number of components and power consumption by providing a FET, an input matching circuit and an output matching circuit in a unit amplifier and adjusting the output matching circuit so as to minimize output distortion of the FET. CONSTITUTION:An output impedance of each of output matching circuits Bout1- Boutn of each of unit amplifiers A1-An is matched so as to provide an optimum intercept point to each of FETs Q1-Qn. The intercept point provides a gain of 33dBm and the distortion of the FET is effectively reduced by widening the gate width. However, the gate width of the FET is limited by a signal band. In this low distortion amplifier, the plural FETs Q1-Qn are operated in parallel to attain the same performance as that of the case when the gate width is extended. Thus, each FET whose gate width corresponds to a required operating frequency band is adopted. Thus, the intercept point is much more improved by adjusting optimizingly the output impedance of each of the unit amplifiers A1-An.

Abstract: PURPOSE:To omit transmission/reception of signals between a conventional moving element and a control part and installation of a feeding cable by making it possible to detect an absolute position on a coordinate plane even after floating the moving element once from the coordinate plane. CONSTITUTION:When a switch 22 is depressed, a light beam 100 radiated from a light emitting part 12 at an angle alpha is reflected by a reflector 23 on the moving element 20 and received by a light receiving element of #m. On the other hand, a light beam 101 radiated from the light emitting part 12 at an angle beta is reflected by a reflector 23 on a different plane of the moving element 20 and received by a light receiving element of #n. When the switch 22 on the moving element 20 is not depressed, the reflectors 23 are shielded by shutters 21, so that reflection is not generated. Thereby, alpha, beta, #m, and #n can be found out at the depression of the switch 22 by scanning the light emitting part 12 periodically at a certain time interval with the angle theta of 0 deg.<=theta<=90 deg. and the coordinates of the moving element 20 on the coordinate plane 10 can be uniformly determined.
