Title: Electronic device
Inventor: MATSUGI TAISUKE
IPC: H01L23/467
Filed: 1989-06-26
Abstract: PURPOSE:To mount electronic parts having big calorific value together with electronic parts on the same printed board while obtaining effective dissipation by cooling compressed air, removing condensed water in a downstream drain bank and injecting air on the electronic parts from a cooling nozzle. CONSTITUTION:Air being rid of dirt by an air filter 10 is compressed by a compressor 9 to rise in its temperature. Being cooled by a heat sink 1, the condensed water generated at this time is stored in a drain bank 5 for being discharged outside by property opening a drain cock 6. The air being cooled and reduced in a water content is injected toward the electronic parts 2 having big calorific value from a cooling nozzle 7, while the air having cooled the electronic parts 2 is discharged outside from an air outlet 11 provided on a box body 8. Thereby, the electronic parts 2 having big calorific value similarly to the other electronic parts can be mounted on the printed board 3 while efficiently cooling the electronic parts 2.

A perpendicular can be drawn down on the segment to connect the adjacent points of front and rear paths Pi-1, Pi+1 from the midpoint Pc and the minimum segment of the length of the perpendicular is selected. Smooth curves f(t), g(t), h(t) to pass points (Pi, j, Pi, j+1, Qs, Qe, Rs, Re) on both ends of the respective segments are calculated. An auxiliary point PjH is inserted between the points Pi, j, Pi, j+1 by a midpoint f(1/2) of the curve for the path Pi and positions g(tq), h(tr) on the respective curves corresponding to positions Qc, Rc of respective legs. The auxiliary points are inserted between respective points, the auxiliary points are added to a command point string of the path Pi and the smooth curve is calculated.  Such calculation is similarly performed for respective paths as well, the difference in levels between the paths are eliminated and the curve is made to be smoothly continued.

Abstract: PURPOSE: To make it possible to plate a substrate for titled board uniformly at high denseness, by arranging an anode plate having arc-shaped projecting part facing to a cathode made of an insulating plate having electroconductive through hole wall, and by plating the one side of the insulating plate alternately by applying pulse current across the electrodes.   
     CONSTITUTION: An anode plate 300 having arc-shaped projecting central part is arranged facing  to the one side of a cathode plate made of insulating plate 100 which is to be used e.g. as a substrate for a printed wiring board and which has electroconductive through hole wall, then pulse  current is applied across both electrodes by connecting an electric power source 400 to the electrodes. At first, electroplating is performed with the anode 300 arranged on the right side of the  substrate 100, then with the anode 300 arranged on the left side of the substrate 100, said alternative arrangement being repeated 1W60 times, hereby plating is iniformalized by controlling the  increase in denseness at the circumferential end of the substrate 100. Installation of a shield board  200 having large aperture ratio at the central part between the cathode plate 100 and the anode  plate 300 exhibits the same effect as the anode 300 having curved structure. This method is particularly effective against the substrate having a large hole diameter: plate thickness ratio.

IPC: G01R29/12
Filed: 1990-06-22
Abstract: PURPOSE:To detect a minute electrostatic capacity under an adequate sensitivity by making the dump amount of Q of a ceramic resonator variable with a control input of variable impedance circuit. CONSTITUTION:When the change of minute electrostatic capacity is detected by a detection part 3 under the state that an oscillating frequency signal is being outputted from an oscillation circuit 1, the resonance frequency of ceramic resonator 12 is deviated, and an amplitude modulation wave, the carrier wave of which is the oscillating frequency signal of circuit 1, is produced and applied to a detection circuit 4. In the circuit 4, the AM wave is detected and outputted as a detection signal for electrostatic capacity change. When a DC input is applied from a control input terminal 11, at the detection of this minute electrostatic capacity, the value of voltage level outputted from the resonator 12 is changed in accordance with the amount of the input. Consequently, in the case the Q of resonator 12 is made large to detect the minute electrostatic capacity with ultrahigh sensitivity, the control input is made to zero, and when the detection is made with low detection sensitivity, the control input signal is applied.
