Title: Microwave integrated circuit package
Inventor: NAGATA EIJI
IPC: H01L23/02
Filed: 1992-06-03
Abstract: PURPOSE:To avoid the deterioration in the isolation from output side to input side as well as in the frequency characteristics by the waveguide transmission mode and resonance mode excited inside a MIC package by a method wherein a resistive thin film is formed on the inner side surface of a cap of the MIC package. CONSTITUTION:Within the title microwave integrated circuit package composed of a cap 5 and a header 1, a resistive thin film comprising Ta is formed on the whole inner side ceiling surface of the cap 5 by sputtering step. Thus, the electromagnetic waves of waveguide transmission mode and resonance mode are attenuated by the resistive thin film 6. Accordingly, even if the inner side width of the package fails to meet a specific requirement, the isolation from the output circuit side to the input circuit side inside the package can be satisfactorily secured by the existence of the resistive thin film 6. Therefore, any unfavorable effect on the circuit operations can be averted.

Title: Quality judgement of cam surface
Inventor: UNO HIROSHI
IPC: F01L1/46
Filed: 1989-06-30
Abstract: PURPOSE:To judge in a short time with high accuracy whether the surface of a cam is of high-quality by comparing the data based on the collected displacement data of said cam with the displacement data of a master cam collected under the same condition. CONSTITUTION:A measuring element (s) of a displacement detector Sy is brought to butt against the surface of a cam (c) fixed in a predetermined state. The measuring element (s) is then linearly moved in a direction orthogonal to a rotating axis (o) of the cam (c). The displacement data of the cam surface in a preset section are collected. Then, the data based on the collected displacement data are compared with the master data based on the displacement data of a master cam collected under the same condition. Whether the cam surface is of high-quality can be detected from the result of the comparison whether the data based on the collected displacement data are within a predetermined range to the master data. Since the cam surface is detected through comparison with the data of the master cam collected under the same condition, the cam (c) is not necessary to be rotated, thereby generating no errors in the detection of the cam surface. Accordingly, the cam surface can be judged correctly in a short time.
