摘要:
A semiconductor device with multilayer wirings can be produced with high yield by applying a liquid source for silicate film to a surface of a chemically vapor deposited insulating layer placed on a surface of the semiconductor substrate in order to provide a smoothed surface. After solidification of the liquid source, the substrate is subjected to a controlled etching to leave the same contour as the one of the smoothed surface on the resultant surface. An upper wiring layer is placed on the resultant smoothed surface in contact with a lower wiring layer through the insulating layer thereby decreasing disconnections in the upper wiring layer which could easily be caused by steep edges existing on an insulating surface layer of a conventional device.

A common-source type buffer amplifier circuit has a microphone capsule, a diode and an FET. An output end of the buffer amplifier circuit, or a drain of the FET is connected to an input end of the current mirror circuit. An output end of the current mirror circuit is connected to one end of a load resistor of which the other end is grounded. A voltage across the load resistor corresponds to an output of the amplifier and is supplied to the speaker amplifier.

A cooling apparatus for a V-type internal combustion engine has a water pump disposed at a central portion of a front end surface of an engine cylinder block. A cooling water inlet passage, provided between the radiator and water pump for introducing cooling water into the water pump, includes an external pipe extending along the front end of the engine cylinder block and turning into a V-shaped space defined by and between elongated first and second cylinder banks set at an angle relative to each other and an internal passageway formed in the cylinder block. The internal passageway has one end communicated with the water pump and its other end opening to the bottom of the V-shaped space and connected to the external pipe.

A crankcase ventilating system for a V-type, OHC internal combustion engine comprising a substantially hollow engine body structure having a pair of upwardly diverging cylinder banks and an oil pan secured to the body structure from below to define a crankcase, and also having a pressure buffer chamber, defined between the cylinder banks, at least one engine cylinder, defined in each of the cylinder banks, and a cam chamber defined therein at top of each of the cylinder banks, and an intake system for the introduction of a controlled combustible air-fuel mixture into the engine cylinders. The system comprises first separate oil return passages each defined in the body structure and communicating between the respective engine cylinder and the buffer chamber, and a connecting passage communicating between the buffer chamber and the crankcase. The connecting passage comprises a blow-by gas passage portion, having one end in communication with the crankcase and the other end projecting a distance into and in communication with the buffer chamber, and a second oil return passage portion having one end in communication with the crankcase and the other end opening at the bottom of and in communication with the buffer chamber.
摘要:
An object is to provide an immunoassay method requiring neither a solid-phase immobilization step nor a washing step, enabling quick and simple quantitative measurement of a target substance in a liquid phase and capable of visualizing an antigen. Such an object is attained by measuring the concentration of a target antigen present in a test substance by sequentially performing a step (a) of bringing an antibody light-chain variable region polypeptide and an antibody heavy-chain variable region polypeptide labeled with a fluorescent dye into contact with an antigen in a test substance in a liquid phase; or bringing an antibody heavy-chain variable region polypeptide and an antibody light-chain variable region polypeptide labeled with a fluorescent dye into contact with an antigen in a test substance in a liquid phase; a step (b) of measuring the fluorescence intensity of the fluorescent dye; and a step (c) of computationally obtaining the level of the antigen contained in the test substance with reference to a positive correlation between the concentration of the antigen in a liquid phase and the fluorescence intensity of the fluorescent dye.
