Title: Production of thermoplastic resin
Inventor: KUDO NORIAKI
IPC: C08F246/00
Filed: 1984-11-06
Abstract: PURPOSE:To produce a thermoplastic resin of excellent heat resistance while keeping the reaction system in a state of a stable emulsion, by polymerizing a mixture of a maleimide monomer and a vinyl monomer in an aq. emulsion in the presence of a small amount of a silicon compound. CONSTITUTION:100pts.wt. monomer mixture comprising 1-50wt% maleimide monomer (e.g., maleimide or N-phenylmaleimide) and 99-50wt% other vinyl monomers copolymerizable therewith [e.g., styrene or methyl (meth)acrylate] are polymerized in an aq. emulsion emulsion at 30-120 deg.C in the presence of 0.01-10wt% silicon compound (e.g., silica powder). Conventionally, when the monomer mixture is polymerized in an aq. emulsion, the pH shifts to an acidic side with the progress of polymerization, the state of emulsion becomes unstable, and polymer deposition in a polymerization kettle and on impellers is marked, so that such a conventional process is not suitable for industrial production. By the addition of the silicon compound to the monomer mixture, it is possible to produce the copolymer while the reaction system is being kept in a state of a stable emulsion.

IPC: H04N3/14
Filed: 1987-09-18
Abstract: PURPOSE:To output an end pulse at a fixed pulse width independently of the characteristics of a thin film transistor (TFT) by using a polycrystal silicone as a resistor in a signal delay means of a differential circuit and mixing impurity with the polycrystal silicone by a specific volume. CONSTITUTION:In case of using polycrystal silicone as a resistor 110, its registance value can be almost fixed by controlling the forming condition of the polycrystal silicone thin film and the dose of the impurity. The width of dispersion is <=1/5 the distortion of ON resistance of the TFT. Thereby, the signal delay time of the differential circuit can be almost uniformed and set up to a required value. For instance, about 10<14>-10<20>cm<-3> impurity is dooped in a resister 118 made of the polycrystal silicone. When about 10<20>cm<-3> boron is dooped, about 100kOMEGA/ of rhos at film thickness 1000A can be obtained. Even when solid state image pickup devices having different TFT characteristics are connected to each other, the devices can be operated without fail and rapid reading can be attained.

Title: Aerator utilizing wind force
Inventor: MIYAUCHI SUNAO
IPC: C02F3/22
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to increase the passage air quantity of an air suction pipe and to improve aeration performance by connecting an air suction pipe to the low-pressure part of a water releasing pipe connected to the discharge port of a pump and freely rotatably mounting a wind collecting and pressurizing member at the inlet of this air suction pipe in communication therewith. SOLUTION: The water discharged from a discharge port 2A by operating the pump 2 is released into the water from the outlet of a diffuser 3C. At this time, a negative pressure is generated in a suction chamber 3B by passage of the discharge water through the throttling part 3A of an ejector 3. This negative pressure acts on the air suction pipe 4. The wind collecting and pressurizing member 5 of this time is held in a posture at which its wind collecting port 5A is directed to the windward at all times by the wind direction effect of a wind direction plate 6 so that the wind collected by the wind collecting and pressurizing member 5 is pressurized and is forced into the air suction pipe 4.  In addition, the negative pressure of the suction chamber 3B acts on the air suction pipe 4 and, therefore, the air increased in the quantity is incorporated into the water in the suction chamber 3B of the ejector 3, by which the aeration performance is enhanced.

Title: Actuator shock absorber for magnetic disc device
Inventor: SUZUKI MASAMI
IPC: G11B21/12
Filed: 1985-10-23
Abstract: PURPOSE:To obtain an ideal shock-absorbing characteristic of the titled shock absorber by constituting its shock-absorbing member with a spring made of a superelastic alloy. CONSTITUTION:If an actuator 1 is run away in the direction of arrow X1, a stopper plate 12 fixed on the actuator 1 with a screw hits against the flange 11a of a second stopper member 11, then the stopper member 11 shifts in the same direction. And the coil spring 9 made of Ni-Ti alloy deflects further than its initial bending deltas to convert the impact energy of the actuator 1 into the elastic energy and absorb it, by which the actuator 1 is bufferingly stopped. In this case, the coil spring 9 deflects, for instance, for a distance Xs and absorbes the impact energy corresponding to an area As. Even though the spring 9 bends, its elastic force does not change but is maintained at fs. A breakage of the actuator 1 likely when elastically stopping it can be exactly prevented from occurring even when the speed of the actuator 1 is fast.
