Title: Upward moving bed filtration method
Inventor: ASAOKA MASAO
IPC: B01D29/62
Filed: 1978-10-06
Abstract: PURPOSE: To eliminate clogging of filter material by introducing the water to be filtered from the  lower part of a filter barrel and passing the filtering water through the interface of the descending  filter materials in a convergent state in the upper part of the filter layer then taking it out at the  time of filtering the liquid while regenerating and replenishing the granular filter materials extracted from the bottom of the filter barrel.   
     CONSTITUTION: The SS-contained waste water 3 supplied from inlet port 4 into the lower part of  a filter barrel 1 ascends in the marked direction in granular filter material layer. On the other  hand, the filter materials having captured SS go down the hopper-form part 5 in the direction of  the broken line arrow and enter a filter material transfer chamber 6. Next, the filter materials  ascend in a transfer pipe 9 while making friction with each other and being stripped of the  deposited SS by the force of the air 8 lifting the waver 7 and are discharged into a regenerating-  separating barrel 10. Next, the filter materials are discharged to the bottom of the barrel 10 and  SS is discharged through discharge port 11 as sludge waste 12. The regenerated filter materials  flow down between conical tapered walls 13, 14 and form the filter layer while creating the  natural interface 16 of inverted cone form flowing down in a convergent stage from the wall end  15 of the lower conical wall 14 toward the center of the barrel 1. The waste water to be filtered  gushes out from the interface 16, passes through holes 17 and is taken out as treated water 19  through a takeout port 18.

Abstract: PURPOSE:To reduce the number of the component parts as well as to ensure the ideal characteristics for each control circuit by providing the voltage comparator to be used common as part of the automatic modulation control circuit at the transmitting time and the squelch control circuit at the receiving time respectively. CONSTITUTION:At the transmitting time, voltage comparator 11 containing inverse input terminal (1), non-inverse input terminal (2), output terminal (3), power terminal (4) and earth terminal (5) respectively is inserted to feedback circuit 8 feeding back to pre-amplifier 2 from the output side of modulated signal amplifier circuit 5 via cathode terminal 9 of diode D6 provided at the output side of output transformer 4 in order to constitute part of the automatic modulation control circuit which performs automatic control of the degree of modulation in the CB transceiver. While at the receiving time, comparator 11 is used as the amplifying element for the input signal of squelch Q3. The squelch action point is determined by standard voltage E2 of terminal (2), i.e., the value of resistance R3 and R4. Thus, the difference voltage between variable voltage E1 and E2 of terminal (1) is amplified largely with improved temperature characteristics and a high gain, so the quick response can be obtained for the squelch action.

Title: Method and equipment for plating through hole of circuit board
Inventor: FUJISHIMA HIDEKI
IPC: H05K3/42
Filed: 1990-05-15
Abstract: PURPOSE:To obtain a through hole plating method and its equipment capable of completely depositing electroless plating even when the diameter of a through hole is smaller than or equall to 0.4mm, by passing two or more times catalyst process necessary for deposition of electroless plating. CONSTITUTION:Catalyst 5 is a process for imparting catalyst to copper foils on both surfaces of a substratum layer 11 of epoxy resin or the like of a circuit board. When catalyst 13 is imparted in said process, it happens that the catalyst is not completely imparted to the inner side of a through hole 20. This is because, when the diameter of a through hole is smaller than or equal to 0.4mm, the movement of liquid is decreased, the liquid does not circulate, and therefore the efficiency of catalyst impartment is reduced. However, when catalyst is again imparted in catalyst 6 being a second catalyst imparting process, the catalyst 13 is completely imparted to the inner side of the through hole 20. After rinsing, the catalyst is activated by an accelerator 7, and electroless plating is completely deposited in the through hole 20 in virtue of the catalyst in electroless copper plating 8.

Abstract: PURPOSE:To obtain a picture in which an object such as a person image can be clearly recognized by providing a brightness detecting picture frame signal having a brightness non-detecting area for the bright part of a fixed or nearly fixed background and a brightness detecting area for the most of the other parts of the picture. CONSTITUTION:The brightness detecting picture frame signal is composed of a brightness non-detecting area 8 for the bright part of the fixed or nearly fixed background and a brightness detecting area 7 for the most of the other parts of the picture. This detecting picture frame signal is inputted to a detecting picture frame signal input terminal 2 of an automatic light control circuit. Thus, in a gate circuit 4, the video signal of a bright background 9 having no correlation with the brightness of a background 10 and that of an object 11 inputted from a terminal 1 is obstructed by the area 8, and the most parts of the video signals of the background 10 and the object 11 are passed by the area 7. Thereafter, the video signals are averaged at an averaging circuit 5 and outputted from a terminal 6 as diaphragm control signals. Thus, the person image can be clearly recognized from the output of an image-pickedup scene which is fixed or nearly fixed.
