Title: Manufacture of double-side printed wiring board
Inventor: HASEGAWA AKIRA
IPC: H05K3/20
Filed: 1988-01-19
Abstract: PURPOSE:To make it possible to manufacture a double-side printed wiring board at a low cost, by bending a printed wiring film in an approximately U-shape, molding a resin in a gap formed in the inside, and forming a unitary body of the molded resin board and the printed wiring film. CONSTITUTION:A printed wiring film 11 is bent in an approximately U-shape at the intermediate part. A flat gap 12 is formed in the inside. Under this state, the film is set in metal molds 21 and 22. Resin is injected into the insides of the metal molds 21 and 22 through a sprue 26. When the metal molds are removed, a unitary planer body of a molded resin board 27 and the printed wiring film 11 is obtained. When a base film 13 is released from the planar body, a double-side printed wiring board 28 is obtained. In this way, the double-side printed wiring board 28 under the state wherein wiring patterns 14A and 14B on the upper and lower surfaces are conducted, can be simply manufactured without machine through holes. Thus, the cost can be reduced.

Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for efficiently predicting dielectric breakdown over aging (TDDB) over a wide region with fewer number of insulating film samples. SOLUTION: In this predictive method, in a process 11, plural insulating film samples having a fixed thickness and a fixed area are prepared, and dielectric breakdown voltages thereof are measured. In a process 12, the film thinning quantities of respective insulating films are calculated from data provided in the process 11. In a process 13, the data provided in the process 11 are sorted, and a dielectric breakdown voltage distribution is determined. In a process 14, the defect distribution (number of defects per unit area) of insulating films is found from data provided in the process 13. In a process 15, the defect distribution provided in the process 14 is determined as a function of film thinning quantities of insulating films provided in the process 12.  In a process 16, while using the defect distribution which is determined as a function of film thinning quantities in the process 15, TDDB at an arbitrary voltage and an arbitrary temperature are predicted concerning the insulating film of an arbitrary area.

Abstract: PURPOSE:To put an irregular impact excitation method in practice without manual operation and to achieve not only the facilitation of measurement but also measuring accuracy and stability, by driving an exciter on the basis of the signal of a signal generator irregularly generating a pulse like signal. CONSTITUTION:A force detector 8a is mounted to the impact part of the exciter 2 suspended at the position close to a structure 10 being an object to be measured by wires 20 and the force added by the impact of the exciter 2 is detected by said force detector 8a.

This irregular pulse like signal is passed through a filter to adjust the pulse width thereof to a degree suitable for operating the exciter 2 and imparted to the exciter 2 as an excitation signal. Since the exciter 2 irregularly applies impact to the structure, by measuring the excitation force detected by the force detector 8a and the vibration response (e.g., vibration acceleration) of the structure 10, a frequency response function can be calculated.

Filed: 1992-01-21
Abstract: PURPOSE:To provide a device for detecting stopping of rotation of a rotary machine, capable of outputting the point of time of finish of machining as reliable information after the rotary machine has machined material. CONSTITUTION:The rotary motion of a rotary machine 1 is transmitted by an air pintle 2. A pulse of a frequency corresponding to the number of rotation is obtained from an encoder 3 mounted to the air pintle 2 and is converted into voltage by an F/V convertor 5. This output is compared with a reference voltage 6 corresponding to a first predetermined number of rotation by a comparator 7. The output is also compared with a reference voltage 9 corresponding to a second predetermined number of rotation by a comparator 10. As the number of rotations is decreased and the comparator 7 is inversed, a retriggerable on-shot mutlivibrator 8 operates and outputs a pulse (C) of a fixed width of time. As the number of rotations is further decreased, the comparator 10 is inversed and outputs a pulse (D). The logical product of the pulses (C) and (D) is obtained to provide an output (E).
