Title: Production of chlorinated resin
Inventor: MIWA KUNIHIKO
IPC: C08F8/00
Filed: 1982-02-25
Abstract: PURPOSE:To prevent the formation of by-products and the presence of unreacted chlorine gas and produce a chlorinated resin effectively, by dissolving chlorine gas in a system prepared by dissolving (dispersing) a resin in a solvent and irradiating the resulting solution (dispersion). CONSTITUTION:A resin to be chlorinated (e.g., polyolefin, ethylene/vinyl acetate copolymer, diene polymer) is dissolved (or dispersed in the form of finely divided powder) in a solvent resistant to a chlorination reaction (e.g., carbon tetrachloride, water), then a necessary amount of chlorine gas is introduced into the system and dissolved therein at about 30-50 deg.C (in this state, the system is yellow), and the system is irradiated with ultraviolet rays under agitation until the color of the system disappears. When the chlorination of the resin is carried out in several stages, the 2nd and subsequent chlorination reactions can proceed  as soon as chlorine gas is dissolved in the system. Therefore, it becomes possible  to carry out the subsequent chlorination reactions at a markedly decreased  dosage of ultraviolet rays.

Title: Detector for rotating directions and rotating speeds of ac machines
Inventor: NOMURA TOSHIHIRO
IPC: G01P3/44
Filed: 1978-03-14
Abstract: PURPOSE: To enable the rotating directions and speeds of AC machines to be detected with always stable accuracy by rectifying the electromotive force in synchronization to the rotating vector obtained through operation of the electromotive force.  
     CONSTITUTION: Electromotive force is operated from the terminal voltage and current of an AC machine 10. From this electromotive force, magnetic flux is operated with a magnetic flux operator 18. The phase of the magnetic flux having been operated is advanced by 90° with a vector rotator 20 so that the magnetic flux having been phase shifted becomes in-phase when it is forward rotation with respect to the electromitive force vector and anti-phase when it is backward rotation. Further an electromotive force rectifier (R 1  thru R 3 , switching elements 22 thru 26, R 4 , operational amplifier 28) is provided and the electromotive force is synchronously rectified in synchronization to either one of positive or negative half wave of the magnetic flux having been phase-shifted by the rotator 20. From the polarity and magnitude of the rectified output voltage EUVW, the rotating directions and speeds of the AC machine are detected.

Title: Nozzle of gas-sampling/supplying tool for inspection
Inventor: NISHIDA MITSUTERU
IPC: G01N1/00
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To efficiently inspect a gas detector without thermally damaging the cover of a gas detector and greatly increasing costs by providing a heat- resistant cover that can freely cover a nozzle body and can be freely removed from the nozzle body. SOLUTION: In a gas-sampling/supplying tool A for inspection, a nozzle N of combustion flame (a) such as a gas cooking stove and a gas lighter is inserted for sucking and sampling a combustion gas as gas for inspection. Then, the nozzle N is inserted into an inspection hole (c) of a cover (b) of a gas detector B for discharging and supplying the gas for inspection to a gas sensor S. A heat-resistant cover 5 is mounted on a holder 2 while the cover freely slides for changing a state where a nozzle body 3 is covered with the cover for sampling the gas to that where the cover is removed. Therefore, the heat- resistant cover 5 is inserted into the combustion flame (a) for sucking while the cover 5 is set to a covering state, thus suppressing the heating of the nozzle body 3 due to the combustion flame (a) for avoiding high temperature.  Also, the heat-resistant cover 5 is set to a state where covering is released for inserting into the inspection hole (c), thus preventing thermal damage around the inspection hole (c).

Title: Gas lighter fuel injection valve structure
Inventor: KURAFUJI HIDEKI
IPC: F23Q2/16
Filed: 1990-02-09
Abstract: PURPOSE:To inject fuel more smoothly by forming a ring-like exhaust passage having a V-shaped cross section and a cone-shaped basic end in the lower part on a valve box side, which is formed as a narrow passage, and moving both a sealing material and a movable nozzle to a fine exhaust passage forming position in an interlocking manner with a narrow passage forming edge. CONSTITUTION:When a non-fuel is to be injected, a seal material 4 comes to contact with the top 16U of a movable nozzle 3 at its neck 16 and blocks a branch hole 17S and closes a narrow passage forming edge 11 of an exhaust passage port 10 having a V-shaped cross section formed on a side of a valve box. During fuel injection, the seal material 4 is brought into contact with the bottom 16d of the neck 16 16 interlocking with the vertical movement of a movable nozzle 3 which is pushed by a fuel cylinder, and opens the branch hole 17a and holds a position which allows the formation of a fine exhaust passage 19 with the narrow passage forming edge 11 of the exhaust port 10. This construction makes it possible to exhaust air more smoothly and inject fuel more smoothly as well.

Abstract: PURPOSE:To lessen changeover shock caused by the difference in level for torque by dividing a plurality of variable valve timing mechanisms individually or into a plurality of groups, and thereby providing a changeover timing control means which switches each variable valve timing mechanism while being shifted by a specified time. CONSTITUTION:Delivered hydraulic pressure out of an oil pump driven by an engine is led to each oil gallery 42 at the sides of a suction and an exhaust valve for each cylinder via passages 111 which is composed of a main passage 110 while being branched by each cylinder. And each changeover valve 103 the operation of which is controlled by a control unit, is disposed at the branch passages 111. The changeover of each variable valve timing mechanism by each cylinder is controlled while being shifted by a specified time by controlling the change-over operation timing of each changeover valve 103 while a specified time is being shifted by each cylinder. Changeover shock can thereby be lessened by shifting changeover timing for each variable valve timing changeover mechanism by a specified time, which is independent so as to be controllably divided.
