Title: Load alteration measuring method
Inventor: ARIGA ATSUSHI
IPC: H02P23/07
Filed: 1994-12-06
Abstract: PURPOSE: To measure a stirring and granulating process at high precision and stably provide a granulated material with excellent fluidity by measuring a microscopic load alteration in by carrying out frequency analysis for electric power of an induction motor. CONSTITUTION: The electric power of an induction motor for a stirring and granulating apparatus is measured by an electric wattmeter 2, the output of the meter is inputted to an FFR analyzer 3, and after d.c. components are removed, frequency is analyzed by Fourier transformation. Then, analysis is carried out by the FFT analyzer 3 compute the electric power difference Δp1 base on the alteration of phase difference and electric power difference Δp2 proportional to the difference of the phase difference. Since the Δp1 can be measured from the intensity of the components with the frequency about the rotational frequency of a load, the Δp1 can be quantified based on the overall power spectrum in a specified region.  Since the Δp2 is components with frequency two times as high as that of the electric power source, Δp2 can be quantified based on power spectrum with 120Hz if the electric power source frequency is 60Hz. The quantified values are collected by a personal computer 4 and based on the set values obtained from past experiment values, control and abnormality diagnosis are carried out.

Inventor: KIMURA ARATA
IPC: H02P27/06
Filed: 1989-12-22
Abstract: PURPOSE:To suppress voltage oscillation by a method wherein the parasitic capacity of an IGBT(Insulated Gate Bipolar Transistor) is increased or a capacitor is connected instead of increasing the parasitic capacity to absorb the energy of the inductance L of a wiring. CONSTITUTION:Upon recovery of a diode, current, discharging accumulated carriers and charging a parasitic capacitance such as a junction capacitance and the like, is conducted through the diode. When it is supposed that a big capacitor is connected between both terminals of a module, a relation between an energy accumulated by the peak value IRP of the recovery current of the diode and the half period T of resonance is shown by formula I and formula II (L means the inductance of a wiring in the module and C means the total parasitic capacitor of an IGBT and the diode). Accordingly, the peak value V of voltage oscillation can be reduced and the oscillating period T can be elongated by increasing the parasitic capacitance of the IGBT and the diode or connecting a capacitor having a capacitance corresponding to the increased parasitic capacitance.

Abstract: PROBLEM TO BE SOLVED: To provide a multilayer printed wiring board, where a conductor layer and an interlayer resin insulating layer are prevented from separating from each other, and the interlayer resin insulating layer is protected against cracking under conditions such as heat cycles, high temperature, high pressure, and high humidity. SOLUTION: A latticed conductor layer where a roughened layer 5 is formed on a part of its surface is formed on the board of a multilayer printed wiring board. Therefore, the conductor layer is brought into close contact with the interlayer resin insulating layer through the intermediary of the roughened layer 5. Furthermore, an electroplating film is formed on the outer layer of the latticed conductor layer, and a non-electroplating film is formed in the inner layer of the latticed conductor layer. Therefore, the roughened layer on the surface of the conductor layer gets into the interlayer resin insulating layer, and an electroplating film follows the interlayer resin insulating layer even if the interlayer resin insulating layer expands or shrinks attendant on surrounding conditions such as heat cycles, moisture absorption or dryness.  Therefore, the conductor layer is prevented from separating from the interlayer insulating film, and the interlayer resin insulating layer is protected against cracking.

SOLUTION: A protrusion and recess base plate 1 and a film-like resin 2 are mounted on a film 8 of a lower plate 6. The plate 6 is raised, sealingly engaged with an upper plate 5, and evacuated in vacuum to a predetermined pressure by sucking from upper and lower vacuum evacuating ports 10. Then, an atmosphere is introduced from an upper part to open from the vacuum state, and the plates 6, 5 are separated to complete a lamination of the plate 1 and the film 2. The obtained laminate is heated and pressurized by a laminator roll 4 or a planar press to smooth the protrusions and recesses of the laminated surface caused by the protrusion and recess plate 1, thereby eliminating adhesive property fault at the time of forming a circuit. Thus, followability of the resin 2 is good and surface smoothness of the laminate is excellent without a microscopic void.
