Abstract: PURPOSE:To facilitate the decision on the presence of an agglutination reaction, by employing an organic pigment having a color clearly distinguishable from white as carrier to make the carrier adsorb an antibody or antigen. CONSTITUTION:Any of yellow, red, blue and green organic pigments clearly distinguishable from white is dumped into a buffer containing a surfactant and an ultrasonic wave of 25-35kHz is applied thereto to crush the organic pigment to obtain an organic pigment suspension with an organic pigment concentration of 0.5-2.0wt.% and a particle size of 0.05-2.0mum by centrifugal separation of the buffer. Typical of an antibody or antigen is human (rabbit) gamma-globulin, human albumin, streptolysin O and the like and one thereof is mixed into said suspension, for example, at a rate of 200mug per 1mg of the organic pigment together with an additive such as 300mug of bovine serum albumin and the mixture is heated up to 36-56 deg.C so as to make the antibody or antigen adsorb on organic pigment particles.

Title: Acceleration slip control device
Inventor: UCHIDA KIYOYUKI
IPC: F02D41/04
Filed: 1990-11-19
Abstract: PURPOSE:To prevent control by means of value of mu different from an actual road surface condition by calculating friction coefficient of the road surface from vehicle acceleration, and prohibiting the use of the calculated friction coefficient of the road surface for control while travelling on a sloping road in the case of carrying out slip control according to its magnitude. CONSTITUTION:An acceleration slip control device has a slip detecting means A to detect slip volume of a driving wheel, and also has a friction coefficient renewing means C. The friction coefficient renewing means C calculates friction coefficient muof the road surface by using vehicle acceleration detected by means of an acceleration detecting means B, vehicle weight W and a driving wheel load Wr, and in the case the calculated friction coefficient is different from the value mu using at present for control, it inputs new value mu obtained by renewing the value mu to a control means D. The control means D carries out driving torque control according to the renewed value mu and the slip volume. In this case, a sloping road detecting means E to detect sloping road travel is arranged, and when the fact that the vehicle is now travelling on a sloping road is detected, renewal of the friction coefficient of the road surface by means of the friction coefficient renewing means C is prohibited by means of a prohibiting means F.

IPC: H04N11/04
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To generate a clock signal with a fixed phase relation to a reference frequency signal with a simple circuit configuration and also to reduce a quantization phase error. SOLUTION: A digital burst signal obtained from an A/D converter 22 is given to a sampling circuit 28 and a band elimination filter(BEF) 30. Then sampling circuit 28 samples the burst signal by a subcarrier frequency or at a period shifting the frequency by a prescribed amount.

Title: Manufacture of member material for lead frame
Inventor: SEO TAKEHISA
IPC: H01L23/50
Filed: 1989-12-01
Abstract: PURPOSE:To remarkably reduce fin bubbles generated at the time of clad working, between a metal plate and resin, by interposing resin between metal plates, and applying heat and pressure in a vacuum of specified degree. CONSTITUTION:Resin is interposed between a plurality of metal plates, and heat and pressure are applied in a vacuum lower than or equal to 10Torr, thereby manufacturing clad material for a lead frame. The reason why heat and pressure are applied in a vacuum lower than or equal to 10Torr is based on that the air on the interface between the metal plates and the resin is compulsorily extracted and the adhesion is increased. When the degree of vacuum exceeds 10Torr, deaeration effect becomes insufficient and possibility of the decrease of adhesion is generated. The metal bonding surface is desirable to be comparatively rough and the roughness is set as Ra 0.3-0.7mum. Thereby deaeration is facilitated, and resin adhesion is increased by anchoring effect.

Title: Semiconductor device
Inventor: HARA TOSHIO
IPC: H01L27/10
Filed: 1987-12-11
Abstract: PURPOSE:To facilitate local temperature rise at the time of laser beam irradiation, and make cut-off of a fuse easy and sure, by making the laser beam irradiation part of a fuse have a two-layer structure composed of a polycrystalline silicon film and a metal silicide film. CONSTITUTION:A fuse is formed as follows. On a main surface of a semiconductor substrate 1, a field insulating film 2 is stucked, and, adjoining to the film, a rectangular non-doped polycrystalline silicon film 3 and a metal silicide film 4 composed of W-Si are stuck thereon. Both ends of the fuse part formed by using a metal silicide film are connected to aluminum electrode wirings 6-1, 6-2 and link in other circuits. The fuse part formed in this manner is cut off more easily than a fuse made of only silicide, because polycrystalline silicide film has inferior thermal conductivity and low melting point as compared with the metal silicide so that the silicide film combines with oxygen by laser beam energy, and easily disperses.
