Title: Operating rotary shaft sealing device for gas insulating type switching equipment
Inventor: TANIGUCHI YOSHINOBU
IPC: H01H33/42
Filed: 1990-05-09
Abstract: PURPOSE:To reduce the frictional force of a sealing bearing and prevent the increase of the frictional force even if the sealing bearing is left for a long period, by connecting a contact point part to an operating mechanism via an operating rotary shaft, and installing a magnetic fluid sealing bearing which supports the operating rotary shaft and seals the insulating gas in a container. CONSTITUTION:The insulating gas which fills the inside of a container 1 is sealed by a magnetic fluid 18. Accordingly, in comparison with the seal by using a solid material such as sealing packing, the frictional force can be reduced drastically. Further, the magnetic fluid 18 is kept in the gap between the magnetic poles 14 and 15 and a flange 4 by the magnetic flux generated by a magnet 19, and dispersion and leak are reduced. Further, an operating rotary shaft 2 is supported by roller bearings 7 and 8, and pressed to the atmospheric pressure side A by the pressure supplied from a gas pressure side G, and supported in the axial direction by a thrust bearing 9. Accordingly, each size h1, h2 of the gaps between the flange 4 and the magnetic poles 14 and 15 is kept at nearly constant value not only in a static state but during the operation of the operating rotary shaft 2. Accordingly, the force for holding the magnetic fluid 18 is made constant, and the stable sealing performance is obtained.

Title: Switching circuit for operation of chrominance signal matrix
Inventor: ONDA TETSURO
IPC: H04N9/67
Filed: 1986-05-22
Abstract: PURPOSE:To eliminate the generation of a noise in a G signal by forcibly holding the present output state of a switching pulse by an output indicating the absence of a chrominance signal. CONSTITUTION:If the level of the chrominance signal is lower than a prescribed level or brought into a black and white broadcasting state, the output of a black and white detection circuit 44 goes to high level and the output of an inverter G16 goes to low level. In such case, the output of a NAND circuit G13 only goes to high level and the output of a NAND circuit G15 is not changed from the high level. Accordingly, in a flip flop circuit operating by the trailing of an input, a change is not produced. Namely, the output (switching pulse) holds an original state. This indicates that the changeover of a switch 16 is not carried out and means that the direct current offset is not produced in the output. Thereby, at the time of deciding the black and white state, the signal synthesis ratio of a matrix circuit is prevented from switching and the generation of the noise is prevented in the G signal.

A water-cooled jacket 6 having a spacer 9 fitted in the non-cooled part of a graphite mold 5 is provided in this runner X'. This spacer 9 possesses a runner Y corresponding to the mold 5. The water-cooled jackets 6 should be prepared in the same sizes, shapes, kinds, and quantity as the casting slab to be continuously cast in the tundish 1. When exchanging the molds, since the runner X' is large and short, residual hot metal or slag will never deposit, saving the trouble of removing such deposit or repairing. Thus, the mold exchange efficiency may be increased, and the facility cost may be reduced.

Filed: 1990-05-10
Abstract: PURPOSE:To decrease the cracking at the time of production of thin type large-sized porcelain in a roller hearth kiln and to allow efficient production by constituting essential components of specific ratios of clay, pottery stone, wollastonite, and cordierite. CONSTITUTION:The large-sized porcelain is obtd. by shaping the body compsn. for porcelain essentially consisting, by weight %, of 20 to 50 clay, 10 to 40 pottery stone, 5 to 25 wollastonite, and 3 to 10 cordierite, then drying and firing the shaped body in the roller hearth kiln. The shaping property and sinterability of the clay are poor if the ratio thereof is below the lower limit and the deformation at the time of the firing increases if the ratio exceeds the upper limit. The pottery stone requires the high-temp. firing for porcelainization to low moisture absorbance and increases deformation if the ratio is below the lower limit. The coefft. of thermal expansion near the silica transformation point increases and the cracking arises frequently in the cooling process after the firing if the ratio exceeds the upper limit. The strength holding effect of the wollastonite is low if the ratio thereof is below the lower limit and the cracking arises frequently in the cooling process if the ratio exceeds the upper limit. The cracking arises frequently if the ratio of the cordierite is below the lower limit and the high-temp. firing is required for the porcelainization to low moisture absorbance if the ratio is above the upper limit.
