Title: Continuous production of metallic screen for screen printing
Inventor: KAMIJIYOU EIJI
IPC: C25D7/00
Filed: 1979-07-13
Abstract: PURPOSE: To improve the process-ink permeability, water resistance, oil resistamce and the like by a method wherein a stainless-steel mesh is passed through a plating bath while being kept in close contact with a rotary cathode to electrodeposit a metal foil integrally on one side of the mesh.  
     CONSTITUTION: The stainless-steel mesh 1 is introduced into the plating bath 2 in a tank 4 serving also as an anode, and passed through the plating bath 2 while being kept in contact with a rotating cathode drum 5. A metal foil 1' is electrodeposited so as to fill up the surface of the mesh 1 nearer to the anode 4, thereby continuously producing the metallic screen comprising the stainless-steel mesh provided integrally with the metal foil on only one side thereof. The rotating cathode drum 5 may be substituted by a belt-formed conductive sheet 5a traveled continuously through the plating bath 2. For another choice, a thin metal foil 1' may be formed first and then it may be thickened by passing the mesh through a plating tank provided with anodes 10, 11, 12 on only the side of the foil 1'.

Title: Method for nmeasuring dna amplified by pcr
IPC: C12N15/09
Filed: 1992-03-13
Abstract: PURPOSE:To measure a DNA fragment amplified by PCR(Polymerase Chain Reaction) by a sandwich hybridization method using a solid phase in excellent handleability and improved sensitivity. CONSTITUTION:When PCR is carried out in a method for measuring a DNA amplified by PCR, 5' end of one of two kinds of primers is phosphorylated and the prepared product amplified by PCR is treated with gamma-exonuclease to form a single stranded DNA suitable for sandwich hybridization. The single stranded DNA is caught on a solid phase and hybridized with a labeled probe to measure its labeling activity. Since the single stranded DNA is caught on the solid phase, disturbance by re-annealing can be avoided and measuring sensitivity and accuracy are improved.

IPC: H01L21/52
Filed: 1993-04-16
Abstract: PURPOSE:To make it possible to continue die bonding without halting the operation of a device by picking up the tip of a collet with an ITV and spraying a gaseous body to a foreign matter if detected and removing the foreign matter. CONSTITUTION:A collet 2 loads a die 4 on an island 6 on a lead frame 5 and then operates so as to pick up a succeeding die as shown in an arrow F and moves to a ring 3. During the movement of the collet, an ITV 7 picks up the tip of the collet 2 and feeds the image to an image processing device 9 and compares the image with a collet preliminarily memorized and determines the presence of a foreign matter and the type of the detected foreign matter. In case when the attracted foreign matter is a metal, such as solder, a heater 20 installed to the collet 2 is heated by the command from a die bonding control device 10 and the metal foreign matter is softened. After the foreign matter is softened, an air or an N2 gas is fed into a space 22 installed coaxially with a hollow hole 21, thereby blowing off the foreign matter. This construction makes it possible to continue the die bonding.
