Abstract: PURPOSE:To form a branching filter circuit as one independent function part and to mount the branching filter circuit onto the surface stably at low cost by commonly connecting conductors for ground on the front and rear surfaces by through hole plating applied at plural spots around a three-layer printed circuit board. CONSTITUTION:A synthesizing/branching filter is composed of the three-layer printed circuit board laminating two printed circuit boards as shown in a figure (d). When the surface conductor is defined as A, the rear conductor is defined as B and the inner layer conductor is defined as C, a figure (a) shows the patterns of the printed wiring conductors A and B on the front and rear surfaces and a figure (b) shows the pattern of the printed wiring conductor C in the inner layer. These patterns are patterns before laminating the printed circuit boards as the three-layer printed circuit board. For the parts of a circle shown by a dot line on the inside of a circular part, hole boring work is executed in the pose process and through hole plating is applied. Then, respective terminal pads Tx, Rx and ANT of the inner layer conductor C are connected to the respective three independent pads for external connection of the surface and rear conductors A and B by through hole plating.

Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a method by which various laser pulse beam can be made a short pulse as a single-shot pulse and made strong with a simple device by' filling up two kinds of mix Raman medium having a difference in rising time of a vibration level in Raman cells. SOLUTION: A mix Raman medium 21 consisting of two kinds of medium is changed in a Raman cell 11. Thereby, a first rear Stokes light obtained by the result of Raman scattering by a Raman medium rising faster based on the difference of a rising time of a vibration level of two kinds of Raman medium receives power redoubling in rear Raman scattering process, self compression of a pulse width occurs, and it is outputted backward from the Raman cell 11. However, a group of pulses after the second in a pulse train by a Raman medium rising faster is suppressed by Raman scattering light by a Raman medium rising slowly, so that only a single short pulse made strong is outputted.

IPC: B01D35/027
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent lint from clinging to a net, so that smooth circulation of washing water is not impeded. SOLUTION: This filter is so designed that a net 420 mounted on a front panel 410 constituting a pocket type filter 400, in order to filter lint mixed in washing water, is mounted integrally on the inside surface of the reinforcing member 416 of the front panel 410. A washing water accelerating part which reduces the cross-sectional area of space formed between a filter case 500 storing the pocket type filter 400 and a spin-drier, to increase the speed of the washing water poured into the pocket type filter 400 through the space, is formed below the filter compartment 520 of the filter case 500. Thus, because lint filtered by the net is prevented from clinging to the net, circulation of the washing water is smoothed to prevent filter performance from deteriorating and to enhance the washing efficiency of the washing machine.

Title: Flow control of fuel cell power generating system
Inventor: TAKAGI YASUO
IPC: H01M8/04
Filed: 1984-03-06
Abstract: PURPOSE:To prevent performance drop and failure caused by crossover by arranging pressure detectors of air and fuel gas of fuel cell and control valves between fuel cell and bypass passage. CONSTITUTION:Control valves 20a and 20b are arranged between outlets of air line X and fuel line Y from fuel cell (FC) 9 and bypass passages 18b and 18a. Pressure gauges 23a and 23b which measure pressure of air and fuel gas within the FC are installed. When gas flow from bypass passage to the FC is changed, either one of control valves of air line and fuel line is gradually opened in response to predetermined function, and the other control valve is controlled so that pressure difference between air and fuel gas within the FC is suppressed. In the steady operation, the former control valve is completely opened and the latter control valve controls pressure difference between air and fuel gas. When the system is stopped, as the flow rate of the FC is throttled, one valve is closed in response to predetermined function and the other valve is controlled so that no pressure difference occurs.

To the inside surface of the cooling duct 6, in other words, the surface getting contact with a metal sheet 2, an insulation coating 16 is applied except a part, for instance the end part of the circumference direction. Therefore, the metal sheet 2 and the cooling duct 6 are brought into contact with each other at the end part of the circumference direction to make the sheet 2 and the duct 6 equipotential. At other parts, the metal sheet 2 and the cooling duct 6 are electrically isolated by the insulation coating 16 and compressed by a tightening force applied at the time of the winding of the metal sheet 2.
