Title: Polyester fiber bonded bat
Inventor: IRAN MARUKUSU
IPC: D06M101/16
Filed: 1990-09-26
Abstract: PURPOSE: To obtain the subject batt excellent in durability and moisture transporting properties and reduced in flammability by heat-treating a mixture of polyester fibers having a cured film of a slickener having a poly(alkylene oxide) chain with a binder having a lower binding temperature than the softening point of the fibers. CONSTITUTION: This bait is obtained by blending polyester fibers having a cured coating of a slickener comprising a poly(alkylene oxide) chain [e.g. poly(ethylene terephthalate) fibers] with binder fibers having a lower binding temperature than the softening temperature of polyester fibers, then superimposing and processing the blend in plural parallel layers without crosslapping, heat- treating the material at 160 deg.C temperature in a furnace and binding the material at cross over points. Thereby, the batt bound to all of the fiberfills of a polyester having improved durability, moisture transporting properties, soft hand and reduced flammability is obtained.

Title: Eccentric rotary valve
Inventor: UENO YOSHIRO
IPC: F16K5/06
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To provide an eccentric rotary valve simple in structure, excellent in flow rate characteristics, and compact in structure by a method wherein a valve element is provided with a radial size between upper and lower support arms larger than the outline size of a valve plate. SOLUTION: A valve element 30 is formed in such a manner that a relation between the outside diameter (D1) of a truncated spherical shell-form valve plate 31 and an outline size (D2) between upper and lower support arms 32 and 33 extended to the back thereof is set to D1<D2. An inside size between the upper and lower support arms 32 and 33 is set to a value being high as far as possible, and the pass area of fluid is set to a high value. Further, a relation between a valve element size, the inside diameter D3 of the outflow flow passage 12 of a valve casing 10, and the inside diameter D4 of the central part of the valve casing is set to D1<D3 and D2<D4.  From the above, the upper or the lower support arm 32 or 33 of the valve element 30 is inserted from the outflow flow passage 12 side and consecutively, the valve plate 31 is inserted, and finally, the valve element 30 is inserted through a remaining support arm into the valve casing 10. Thus, when a valve rod 20 is mounted on the upper support arm 32 and a support shaft 22 on the lower support arm 33, the valve element 30 is accurately and rotatably mounted in the valve casing 10.

Title: Method for preheating flat nozzle for twin belt continuous casting
Inventor: SADANO MASAHIRO
IPC: B22D11/06
Filed: 1990-09-28
Abstract: PURPOSE:To execute a stable continuous casting operation by covering surroundings in the molten metal flowing end of a nozzle with the upper opening type vessel made of a fusible material with a molten metal introducing combustion gas from the upper end of a vertical penetrating gas flow passage in a stopper and blowing the gas to the molten metal flowing end at the upper end of the nozzle through a molten metal discharging hole in a tundish. CONSTITUTION:As preheat is executed by blowing the combustion gas into the flat nozzle 20 through inside of the stopper 13 closing the molten metal discharging hole in the tundish 10, the preheat can be continuously executed during supplying the molten metal into the tundish from a ladle, and the flat nozzle can be preheated just before casting. Further, since the surroundings in the molten metal flowing the end of the flat nozzle are covered with the upper opening type vessel 30 and moisture in discharged gas is not dewed by hitting the discharged gas flow to a mold wall, there is no danger of occurring of explosion caused by the moisture. Since the upper opening type vessel is made of the fusible material with the molten metal, there is no disturbance to the execution of the casting. By this method, the generation of spalling crack in the nozzle and the stickness of metal to the nozzle at the time of submerged casting, are prevented, and the stable twin belt continuous casting operation is attained.

Filed: 1988-10-13
Abstract: PURPOSE:To eliminate the wastefulness of recording paper by making it possible to record a predetermined number of pages from an end mark even when said end mark is detected. CONSTITUTION:The detection output of the detection means of an end mark 16 provided in an apparatus main body is supplied to a CPU 21.

Title: Driving method for electrooptic display device
Inventor: FUJITA MASANORI
IPC: G02F1/133
Filed: 1985-11-18
Abstract: PURPOSE:To prevent a display element from deteriorating and the contrast from decreasing by applying the display element with AC pulses generated by superposing AC pulses whose frequency is higher than that of display control pulses upon such a pulse group that different-polarity pulses are mutually equal in waveform and number. CONSTITUTION:A selecting circuit SE generates a selection signal which selects one-side electrodes L1-L7 sequentially on a time-division basis and when this selection signal is not supplied, a nonselection signal NS1 is generated. A driving control circuit DR, on the other hand, generates an answer signal D1 or reverse answer signal NS1, which is supplied to other-side electrodes R1-R5. Consequently, an answer display element is applied with a pulse group P1 and a reverse answer display element is applied with a pulse group P2. AC pulses A1 and A2 generated by superposing AC pulses whose frequency is higher than display control pulses are applied by a signal NS1 after pulse groups P1 and P2 are applied. Then, the pulses P1 and P2 and A1 and A2 are different in polarity and equal in waveform and number to prevent the display element from deteriorating and the contrast from decreasing.
