Title: Manufacture of vinyl chloride polymer
Inventor: ISHII YASUMICHI
IPC: C08F2/20
Filed: 1987-12-28
Abstract: PURPOSE:To shorten the time required for charging and the heating time and to improve the operation efficiency of a polymerizer remarkably in aqueous suspension polymerization of a vinyl chloride monomer, by charging a monomer, water, a suspending agent and a polymerization initiator in a specified manner. CONSTITUTION:When a vinyl chloride monomer or a mixture thereof with a monomer copolymerizable therewith is subjected to suspension polymerization in the presence of an oil-soluble polymerization initiator in an aqueous medium, the following procedure is taken. The monomer and preheated water each in a amount of 70wt.% or more of the total feed are charged simultaneously, while a suspending agent in an amount of at least 20wt.% of the total feed is charged during the charging of the monomer. After the amount of the charged monomers has reached 30% of the total feed, and until it reaches 100%, and at the point where the weight ratio of the monomer to the water in the polymerizer is 1.5 or below, the whole of the polymerization initiator is charged, and the polymerization is carried out continuously. It is necessary that the water is previously heated so that the internal temperature (t) of the polymerizer at the time when the charging of all the monomers and the water is completed may be T-10<=t<=T+5( deg.C) for a prescribed polymerization temperature T.

Abstract: PURPOSE:To decrease the clamp potential of a common source wiring, simultaneously decrease a constant at a discharging time constant and to shorten the sense time of a column bar pattern by dividing and arranging a sense amplifier driving circuit in the both edge parts of the common source wiring. CONSTITUTION:In the both edges of a common source wiring the inverse of SAN of a bit line sense amplifier SA which is arranged along a core circuit, sense amplifier driving circuits 4a and 4b are provided and controlled by a low block selecting signal RBS and a sense amplifier activating signal SEN. A word line WL0 is selected and only a first column is caused to be '0'. Then, when a sense is started, the driving circuits 4a and 4b are simultaneously operated and the both edges of the common source wiring the inverse of SAN are linked to a VSS. Accordingly, transistors Q4, Q6...Q8 after an SA2 are turned on and the charge of a bit line is discharged in the two directions of the inverse of SAN. Accordingly, the resistance value of the wiring the inverse of SAN goes to be 1/2 of the conventional value and the clamp potential falls down. Then, the discharging constant is decreased and a sense amplifier transistor Q1 in the column of '0' data is turned on with a rapid timing.

Title: Vehicle driving force transmission control device
Inventor: IKEDA AKIHIKO
IPC: B60K17/344
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a driving force transmission control device for automobiles that provides sufficient durability against vehicle vibrations and foreign objects. SOLUTION: In a clutch device 10, an electromagnet 60 is prevented from turning as it is engaged with an engaging protrusion (engaging member) 92 provided in a bearing retaining member 86 of a bearing retaining unit 90 secured to a vehicle body. As a result, vibration from the vehicle body is transmitted via a cushioning member 84 to the engaging protrusion 92 and the electromagnet 60. This substantially reduces mechanical vibration transmitted from the vehicle body to the electromagnet 60 or clutch device 10, allowing a driving force transmission control device for automobiles to provide sufficient durability.

Title: Production of bismuth-substituted rare earth iron garnet single crystal film
Inventor: HIRAMATSU MASAO
IPC: C30B29/28
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To make it possible to control the corrosion state of the platinum to be used and to suppress the crack of a substrate under crystal growth by charging a crucible material into a melt or pulling up the previously charged crucible material from the melt, thereby executing the liquid surface movement of the melt. SOLUTION: The liquid surface movement of the melt is effectual in controlling the corrosion of the crucible. The charging of the crucible material or the liquid surface moving material is executed as one thereof. A hollow structural body formed by coating Al2 O3 refractories, etc., with the crucible material layer, such as platinum, having about 0.5mm thickness is used as the liquid surface moving material. The liquid phase epitaxy of a single crystal is ended with the melt formed by melting the constituting components of Bisubstd. rare earth iron garnet and the melt temp. is raised during the execution of the next liquid phase epitaxy to replenish the components taken in for the next crystal growth. At this time, the liquid surface moving material is simultaneously charged to raise the liquid surface.  The liquid surface moving material sinks on the bottom of the crucible in the melt and, therefore, the corrosion is slight. This material is recovered at the time of the exchange and is repetitively usable.

Title: Starter for carburetor
Inventor: TSUTSUI KATSUHIKO
IPC: F02M1/16
Filed: 1987-12-28
Abstract: PURPOSE:To enable the supply of a starting fuel quantity matching an engine atmosphere temperature by enabling the restriction of a shift stroke toward the side of an atmosphere chamber for a division body such as a diaphragm for increasing or decreasing the volume of a starting fuel pump chamber with an increase in the engine atmosphere temperature. CONSTITUTION:In starting an engine at a low temperature, an operation lever 20 is first fully drawn toward the left side against the force of a spring 23, and a diaphragm 6 is displaced in the same direction. Fuel in a float chamber 4 is thereby drawn into a starting fuel pump chamber 7 via an intake side check valve 11. Then, a tension force for the operation lever 20 is released and this lever 20 is returned to the right side by the help of the force of the spring 23 and the pump chamber 7 is compressed, thereby injecting starting fuel into an intake passage 2 via a delivery side check valve 17 and the like. On the other hand, at an engine start in a condition where the engine atmosphere temperature rises from a low temperature condition, a thermal expansion and contraction body 33 expands and a movable retainer 32 is moved to the right side. Consequently, the displacement of the diaphragm 6 due to the pull operation of the lever 20, or a starting fuel quantity is reduced.

IPC: B41J2/045
Filed: 1990-11-28
Abstract: PURPOSE:To enable an always stabilized recording state to be secured by supplying smoothly ink even for increase of an amount of air in an ink chamber by a method wherein an intermediate part interconnected to an ink discharge opening and an ink supply tube is formed in a narrow width form in the ink chamber. CONSTITUTION:When a recording head 100 scans laterally, ink I in an ink chamber 106' rolls laterally and ink pressure fluctuates. Then, though a discharge state of a meniscus Io of the ink I becomes unstable due to this pressure fluctuation and inconveniences such as fluctuation, a blur, etc., of a dot are occasionally caused, fluctuation of the ink I itself is restrained little by throttle action of the narrow intermediate part 106a' near an ink discharge opening 107 in this high speed scanning. Therefore, pressure fluctuation in the ink chamber 106' is restrained to keep constant ink pressure, and discharge of the meniscus Io of the ink I is kept in a stabilized state.

SOLUTION: The discharge flow rate at the position of the distance X(mm) along the discharge flow 6 from a discharge port 3 of a dipping nozzle 2 is 1.5d/x times the discharge flow rate at the discharge port, where d(mm) is the diameter of the dipping nozzle at the discharge port 3. The distance to the position where the discharge flow rate from the meniscus is <=1/2 of the flow rate at the discharge port, is expressed by L+3d.sinθ, where L(mm) is the distance from the meniscus 4 to the discharge port, and θ deg. is the angle of discharge from the dipping nozzle 2. To obtain the effect to suppress the stable entering flow, the electromagnetic stirring device is installed in the mold so that the distance from the meniscus to the electromagnetic force application position 5 is >=L+3d.sinθ and <=700mm.  A cast slab less in non-metallic inclusions and bubbles can be manufactured.
