Title: Production of pottery article
Inventor: KAWAI HIDEJI
IPC: C04B33/13
Filed: 1992-05-08
Abstract: PURPOSE:To obtain an apparently soft-toned pottery article by baking a stock formulation incorporated with a specific flux raw material to make a pottery base. CONSTITUTION:The objective pottery article can be obtained by baking a stock formulation incorporated with a specified proportion of a flux material containing 30-100wt.% of 10 to 100-mesh particles (e.g. feldspar) to make a pottery material. In the above production process, only parts being in contact with the peripheral textures among the flux material with a specified particle size distribution reacts to form a vitreous phase, the rest being left unreacted, resulting in the inside of the texture in a sort of uneven state and also in forming ruggedness, on the surface of the flux material particles left on the base surface. The asperities represent round shape with the surface melted, thereby the whole base represents soft-toned planar shape and soft color tone.

Title: Overcurrent preventing circuit
Inventor: AZUMA MASATO
IPC: G05F1/56
Filed: 1987-06-09
Abstract: PURPOSE:To improve the detecting accuracy of an overcurrent by using a bipolar transistor (TR) having small fluctuation to an overcurrent detecting TR. CONSTITUTION:A bipolar TRQ2 is used to an overcurrent detecting TR. A MOS TRQ1 raises the gate voltage of an output TRQ4 up to a VIN level when the overcurrent detecting TRQ2 is turned on. Thus the overcurrent of the TRQ4 is avoided. Thus the overcurrent detecting accuracy is improved since a bipolar TR having small voltage fluctuation between the base and the emitter is used as the TRQ2.

Filed: 1989-06-06
Abstract: PURPOSE:To perform fine welding of high quality on an underwater vertical lap joint by removing water locally in the vicinity of a joint part to form a, cavity and performing welding while executing magnetic stirring by using a welding wire. CONSTITUTION:CO2 shielding gas is first fed and the shielding gas is injected in a shield hood 6 wherein a magnetic stirring coil incorporated welding torch 13 is stored and the water is removed and the local cavity is formed. In this local cavity, a welding arc 17 is generated between the welding wire 15 tip and the vertical lap joint 2 to form a weld bead 18. In addition, while the shield hood 6 being maintained airtight by sealing materials 9 by operating a driving motor 10, it is elevated along a guide shaft 8 and the welding arc 17 is elevated on the vertical lap joint 2 and the weld bead 18 is formed extending over the entire length of the joint. At this time, even if a certain amount of water content remains in the vertical lap joint 2, since a specified magnetizing current is impressed on the welding arc 177, weld metal receives a stirring action and steam is dispersed and raised to the surface and the generation of a blowhole in the weld bead 18 is prevented.

Title: Changing method of quantity of water in water storage tank for building, and block body used for the same
Inventor: ASAKA NAOYA
IPC: E03B11/00
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To adjust the quantity of water stored, and to reduce the stagnant quantity of water and prevent the deterioration of the quality of water, by charging a plurality of block bodies made heavier than water onto the inner bottom of a water storage tank when the tenants of a building are decreased and the quantity of water used is diminished. SOLUTION: A water storage device 1 for the building has a water storage tank 2, a water supply pipe 3, etc. When water is sent into the water storage tank 2 from the water supply pipe 3 and reaches a specific water level, water supply is stopped by the working of a ball tap 7. A block body 12 is set in size, in which the block body 12 can be introduced into the water storage tank 2 from an inspection hole 10, and formed in a cubic shape, and a hook section for taking-in-and-out is formed to the block body 12. The block body 12 is made heavier than water. When the tenants of the building are decreased, the block bodies 12 are introduced into the water storage tank 2. The number of the block bodies 12 entered into the water storage tank 2 is increased in conformity with the reduction of the tenants.  Consequently, the quantity of water collected in the water storage tank can be adjusted in response to the variation of the tenants. Accordingly, water staying at all times is reduced, and the deterioration of the quality of water can be inhibited.

Filed: 1983-08-05
Abstract: PURPOSE:To stabilize a immobilized immunologically active substance by treating in immersion an immunologically active substance immobilized on a carrier with the single presence or coexsistence of a sugar solution, protein solution and lower polyvalent alcohol solution. CONSTITUTION:An immunologically active substance is immobilized on a carrier by the covalent bonding or physical adsorption. The carrier is immersed in a solution of one or more kinds of compounds selected from sugar, protein and lower polyvalent alcohol.

Title: Television signal converter
Inventor: NARITA YOSHINORI
IPC: H04N5/073
Filed: 1993-05-24
Abstract: PURPOSE:To provide a television(TV) signal converter capable of suppressing the disturbance of a picture of an output TV signal. CONSTITUTION:At every input of the prescribed frequency of vertical synchronizing signals in an input TV signal, an I/O synchronizing part 36 outputs a synchronizing signal. At the time of receiving the synchronizing signal from the I/O synchronizing part 36, a synchronizing signal generating part 24 synchronizes an output TV signal with the input TV signal. Thereby the disturbance of a picture due to the deviation of timing between the synchronizing signal of the input TV signal and that of the output TV signal can be suppressed. This TV signal converter is also provided with a horizontal synchronizing signal period rough adjustment part 38 and a horizontal synchronizing signal period fine adjustment part 42 to adjust the field period of the output TV signal so that the ratio of the field period of the input TV signal to that of the output TV signal becomes a simple integer ratio at the time of receiving the synchronizing signal from the I/O synchronizing part 36. Consequently the generation of V jitter due to initialization based upon the synchronizing signal generating part 24 can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To prevent a mode in a set state from being changed to other modes for instance and to improve operability by making the interval between a first state setting position and a second state setting position adjacent to it different from that between adjacent other second state setting positions. SOLUTION: For instance, five kinds of mode's names 11-15 are printed on a mode dial 6. This mode dial 6 is turned to make one of the mode's names coincident with an index 10 provided on the outer periphery of the dial 6, so that the mode is selected. At this time, a display name (AUTO) for a full automatic mode 13 is printed to be larger in size than other mode's names. As the angle between the respective modes, parts (angles α) for holding the full automatic mode 13 are widest. In other words, the intervals (angles β) between modes 11 and 12 and 14 and 15 are set comparatively narrow, but the interval (angle α) between the full automatic mode 13 and the mode adjacent to it is set wide.
