Title: Printed wiring board
Inventor: MIZUNO HIDEAKI
IPC: H05K1/18
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To mount an LSI which generates heat such as a TCP highly efficiently by simple process control by not providing a through hole in a fixed range inside and outside an edge of an LSI chip of a mount region of an LSI chip. SOLUTION: A printed wiring board 3 is not provided with a through hole 3 in a specified region 11 of a part whereon an LSI chip 1 is mounted. An outer diameter of the specified region 11 is made larger than an outer diameter of the LSI chip 1 and than a region whereto and adhesive agent 2 for fixing the LSI chip 1 to be mounted is applied. An inner diameter of the specified region 11 is made smaller than an outer diameter of the LSI chip 1 by a specified amount. Therefore, it is possible to avoid contact defect, etc., generated by change of the state of the adhesive agent 2 caused by the fact that preliminary solder stops up the through hole 3 provided for heat dissipation of the LSI chip 1 which generates heat without complicating control of an application amount and an application region of the adhesive agent 2.

Abstract: PURPOSE:To prevent the scattering of condensed water to the fan provided to the rear stage of a heat exchanger used, for example, in a heat pump type air conditioner or freezing refregerating machinery or to the circumference thereof and to also prevent the damage to the fan due to icing. CONSTITUTION:A heat exchanger 1 is arranged on the suction side of a fan 4 and a filter 5 is arranged between the fan 4 and the heat exchanger 1. When the fan 4 is rotated, the open air passes through the heat exchanger 1 and the filter 5 to be sucked by the fan 4. At this time, the air passing through the heat exchanger 1 is subjected to heat exchange by the heat exchanger 1 and contains condensed water 7 not removed by the heat exchanger 1. This condensed water 7 is removed by the filter 5 and the adhesion of the condensed water to the surface of the blade of the fan 4 is prevented.

Filed: 1979-08-22
Abstract: PURPOSE:To obtain a correct ratio getting rid of fading effect by selecting outputting speed signals larger in the level corresponding to ground speeds detected with two Doppler modules so arranged to deviate the polarized surfaces by a specified angle from each other. CONSTITUTION:Ground speeds are detected with Doppler modules 5 and 6 provided parallel with the body of a vehicle so arranged to deviate one polarization surface by a specified angle, for example 90 deg., and corresponding speed signals ea and eb are separately inputted into Schmitt trigger circuits 13 and 14 and detectors 15 and 16. Square wave signals Pa and Pb from Schmitt trigger circuits 13 and 14 are inputted to frequency voltage converters 17 and 18 and analog signals Va and Vb are applied to analog switches 20 and 21. On the other hand, a comparator 19 turns on a switch 21 to select a signal Vb when ea'<eb' in comparison of the level thereof while turning on a switch 20 to select Va when ea'>eb' as true ground speeds respectively. This allows a slip ratio es to be obtained from a Vc/drive wheel speed signal Vd free from any fading effect.

Abstract: PURPOSE:To issue exact response signals and make it possible to obtain signal for determining a correct cooking time by providing detection sections with strain gauges for detecting the amount of deflection of the second spring plate at approximately the center section in the direction of the plate width, in two places at a spot near the stem side of a second spring plate and at a spot near the end side. CONSTITUTION:A second spring plate 13 is installed so as to be positioned at approximately below the axial line of a shaft 9a and two strain gauges 8a and 8b are mounted at two places on the lower face of the spring plate as detection sections. Those places are the positions where the largest stain develop when the moving end is lowered, that is at the spot near the stem side of the second spring plate and at the spot near its end side and nearly at the center of the width of the plate. When an object to be thermally treated is placed on the central section of a rotating base 2, its weight is transmitted to the movable end 15 through a shaft 9a and electric motor mechanism 9 to lower the movable end 15, and as a result corresponding signals are generated at the strain gauges 8a and 8b. If a cooking time is set by utilizing the signals, it becomes possible to set the cooking time which corresponds to the weight of an object to be thermally treated. If an object 3 to be thermally treated is shifted to one side, the case 9 of the electric motor mechanism tilts. With this tilting a first spring plate 12 is subject to a biased load, but the second spring plate 13 is not subject to a large twisting.

Abstract: PURPOSE:To provide a high quality and equal white balance over the full screen. CONSTITUTION:Added color signal sampled at sampling circuits 10 and 11 is sent to multiplexers 12 and 13 and to a WB compensation control circuit 14. The WB compensation control circuit 14 detects the ratio between a specified color component of the added color signal and other color components when a white object is exposed and calculates a WB coefficient to be multiplied with an added color signal so that the ratio becomes equal over the full screen. The multiplexer 12 and 13 multiply a WB coefficient with an added color signal to adjust the white balance of the screen. This results in a high quality and equal white balance to the full screen.

Abstract: PROBLEM TO BE SOLVED: To obtain higher rigidity, to enlarge a motor space, and to reduce costs by bending an iron plate along a 1st bend part by pressing, and forming the cross section in a U-shape in one body. SOLUTION: For example, a 1st bend part 13 and a 2nd bend part 14 between both end parts of a 1.4 mm thick iron plate, which has a Young's modulus several times higher than that of an aluminum plate of the same thickness, are bent into two steps by pressing, and a base part and a side rail part are formed into one body structure. Here, since the 1st bend part 13 is provided with 20-30 mm notch parts, the iron plate can easily be bent squarely along the 1st bend part 13. Moreover, since the circumferential part of a motor mounting part 7 is provided with an annular rib 16, the motor mounting part 7 obtains higher rigidity, and this prevents the motor mounting part 7 from being deformed even when the outer part of the rib 16 is deformed at the time of pressing.
