Abstract: FLOW IMAGING CYTOMETER ABSTRACT OF THE DISCLOSURE:       A white-light image and a fluorescent image are capable of being captured by a single video camera, and a single light source for producing exciting light is used to pick up the fluorescent image and monitor arrival of particles to the image capturing area.  Specifically, besides a strobe light source, a light source, the output of which normally is low, is provided for exciting fluo-rescence and for monitoring cell flow-through.  An image intensifier is used in the light-receiving system of the fluorescent image and is supplied with a voltage the size and timing of which are controlled in such a manner that the irradiation of a cell with the strobe light when the white-light image is captured will not have an adverse effect upon the aforementioned light-receiving system. This makes it possible to pick up two images each in a different zone on the light-receiving surface of image capturing means.

Abstract: In an optical communication system with a passive star coupler, measurement between a station and a central node should not interfere with the operation of other stations. Distance measurement is accomplished by determining the echo delay using a wavelength not being used by other stations. The system uses combined wavelength- and time-division multiplexing. One wavelength is always kept free for measurements if possible. For the measurement, the same data format as that employed during normal operation can be used. Measurement can be continuously repeated unchanged during operation.

Abstract: ABSTRACT An improved crankcase gasket, for use in an internal combustion engine with a vertical crankshaft, having web portions that substantially cover the oil sump.  The construction of the crankcase gasket baffles oil thrown around the inside of the engine by mechanical turbulence and prevents excess oil from reaching the cylinder bore.  Gasket material under the valve spring box drain operates as a check valve and eliminates the need for an expensive valve stem valve.  Oil temperature is reduced with an increased ability for engine operation at greater angles of crankshaft tilt from vertical.

Title: Process for conducting site-directed mutagenesis
Inventor: SLILATY STEVE N
IPC: C12N15/10
Filed: 1990-10-26
Abstract: The present invention relates to an approach to site-directed mutagenesis of double-stranded DNA. This approach involves the generation of structures capable of directing full-length complementary-strand synthesis of DNA. The structures are formed following heat denaturation and cooling of linear DNA templates in the presence of what is a ''closing'' oligonucleotide. This closing oligonucleotide is a nucleotide sequence having at least part of its sequence complementary to at least one of the free ends of the DNA  template. The closing oligonucleotide functions as an agent for circularization of a DNA strand and generation of a primer-circular template structure suitable for polymerase-dependent full-length complementary-strand synthesis and ligation into a covalently-closed heteroduplex DNA molecule.
