Inventor: KONNO HIDETOSHI
IPC: C08G18/79
Filed: 1992-02-21
Abstract: A crosslinked polyurethane polyurea spherically particulate polymer having an average particle diameter of 0.1 to 500 µm, wherein the polymer molecule contains an isocyanurate ring in an amount of 10 to 30% by weight is disclosed. A process for producing the crosslinked polyurethane polyurea spherically particulate polymer is also disclosed. The process comprises the steps of: reacting an isocyanurate ring-containing polyisocyanate compound with a polyhydroxy compound to form an organic phase capable of forming a three-dimensional crosslinked structure due to the reaction, wherein the amount of isocyanate groups in the polyisocyanate compound is stoichiometrically larger than that of hydroxyl groups in the polyhydroxy compound; finely dispersing the organic phase into water; and adding a polyamine to the dispersion to make interfacial polymerization between the organic phase and the polyamine and a polyurethane-forming reaction within particles, wherein the amount of the polyamine is stoichiometrically equivalent to or smaller than the stoichiometrical excess of isocyanate groups. The particulate polymer is excellent in solvent resistance and has a completely spherical shape without wrinkle on the particle surface. The particulate polymer has a good toughness and mechanical properties. Further, the particulate polymer has no reactive isocyanate group in the polymer molecule.

Abstract: A method and a device for coding and decoding an analog low-frequency signal into a PCM format, especially for transmitting speech information in a simplex or duplex intercom system. The low-frequency signal is re-coded through A/D conversion into a digital signal, where an 8-bit data word corresponds to each sampling value. Each data word is transmitted in a time slot of a PCM frame on the PCM multiplex line. On reception, the data words are decoded through D/A conversion into an analog low-frequency signal. For the transmission of speech signals with a bandwidth between 7 and 8 kHz, the sampling frequency of the A/D-D/A conversion is twice the PCM synchronisation frequency and, on transmission following coding, every other data word is temporarily stored until the following data word is available and the consecutive data words are sent to the PCM multiplex line in such a way that they occupy two consecutive time slots. On reception, the data word obtained from the first time slot is in each case decoded immediately, while the data word obtained from the second time slot is temporarily stored until the decoding of the preceding data word is completed. <IMAGE>

Abstract: A wavelength variation measuring apparatus is disclosed. A light beam from a light source device capable of controlling an oscillation wavelength is divided into two light beams by a light divider. A predetermined optical path length difference is imparted to the divided light beams to synthesize the beams by a light synthesizer. A part of the synthesized light is used as detection light and the rest of the synthesized light is used as measuring light. A beat signal is detected from the detection light by a photodetector. A feedback control is effected to the light source device by use of the beat signal to thereby stabilize the oscillated wavelength of the light source device and to direct the measuring light to an object to be measured. The beat signal is rendered as a measurement data correction signal, and measurement data obtained by directing the measuring light to the object to be measured is corrected.

Abstract: In a method for forming a semiconductor wafer with a cleavage plane as an orientation flat, a groove or a hole is formed through the substrate so that it may be on a line along which the substrate is cleaved to form an orientation flat, and surface treatment is applied to the substrate to provide a mirrorlike surface of the substrate. Then, the substrate having the mirrorlike surface is cleaved from the groove or hole to form the orientation flat. Accordingly, edges of the cleavage plane are not rounded due to the surface treatment. In addition, the substrate is easily cleaved along the cleavage plane from the groove or the hole. As the result, a semiconductor wafer having a sharp cleavage plane as an orientation flat is produced with improved yield, and an alignment is performed with high precision in a subsequent process, such as a photolithography.

Abstract: A housing accommodating a fur brush and a cleaning blade is pivoted to a position close to a photoconductive drum or at another position far from the photoconductive drum by positioning a positioning shaft. When the positioning shaft is slid for moving the positioning shaft away from a photoconductive drum, an operating member attached to the positioning shaft is put into contact with a pivoting lever to raise the pivoting lever away from the photoconductive drum. Since the pivoting lever is attached to a blade shaft, a cleaning blade attached to the blade shaft is pivoted away from the photoconductive drum.
