Abstract: PROBLEM TO BE SOLVED: To uniformize the discharge state and to improve the concn. of generated ozone by providing the ozonizer with an ozone generation tube(s) consisting of a grounding electrode on the inner surface of which a dielectric layer is formed, and a high voltage electrode placed on the inner side of the grounding electrode and improving the uniformity of a discharge gap formed between these two electrodes. SOLUTION: In this ozonizer provided with an ozone generation tube(s), the ozone generation tube consists of a hollow cylindrical grounding electrode 5 on the inner surface of which a dielectric layer 52 is formed and the both ends of which are open, and a high voltage electrode 6 placed on the inner side of the grounding electrode 5 through a discharge gap 56, wherein a gaseous raw material is allowed to flow into the discharge gap 56 through one opening of the grounding electrode 5 to ozonize the gaseous raw material by silent discharge and the generated ozone is withdrawn through the other opening of the grounding electrode 5.  In the ozone generation tube, the parallelism between the opposing surfaces of the grounding electrode 5 and high voltage electrode 6 and uniformity of the discharge gap 56 are improved by subjecting the surface of the high voltage electrode 6 to mechanical polishing, pressing the surface of the high voltage electrode 6 or the surface of a base tube of the grounding electrode 5 with e.g. press rollers, while moving the electrode 6 or 5 in the longitudinal direction, or adjusting the thickness of a glass layer for lining the inner surface of the grounding electrode 5, to about <=1 mm.

Title: Digital signal processing system
Inventor: ABE MASATOSHI
IPC: H04M3/56
Filed: 1983-10-13
Abstract: PURPOSE:To provide digital time-division electronic switching with a diversity of circuit switching service by adding data for circuit data processing to circuit switching data from a control memory. CONSTITUTION:Data for the modulation, attenuation, composition, etc., of a signal of a circuit is added to corresponding circuit switching data from the control memory CM. When an ordinary circuit switching connection is made, data sent to a channel memory SPM and a signal attenuating circuit PAD are used and signal switching in the term of the signal switching of a common part is made ineffective. When signal processing is performed through the circuit, signal switching in the term of the signal switching of the common part is made effective and the circuit number is written in an additional channel memory ASPM and an additional signal attenuating circuit APAD. Consequently, when the signal is mixed with a signal of another channel, the objective channel is replaced at the same time on the additional signal attenuating circuit APAS to synthesize data.

Title: Double-voltage smoothing circuit
Inventor: KANAIDA IKUYUKI
IPC: H02M7/06
Filed: 1990-07-20
Abstract: PURPOSE:To facilitate a highly reliable double-voltage smoothing circuit having a reduced size structure by a method wherein rush current suppressing resistors which are connected to avalanche diodes in series and suppress currents applied to the avalanche diodes are provided. CONSTITUTION:Current suppressing resistors 6 are connected in series to two avalanche diodes 5 respectively. When a voltage outputted from a rectifying diode 2 exceeds a predetermined voltage and the avalanche diodes 5 start avalanche operation, currents applied to the avalanche diodes 5 are suppressed by the current suppressing resistors 6. Therefore, large current capacity avalanche diodes are not necessary. From the viewpoint of design, the values of the current suppressing resistors 6 are so determined as to have rush currents at the time of the start of the avalanche operation within a range of the rated current capacity of the avalanche diodes 5.

Title: Refining method for molten steel
Inventor: SAITOU TETSUYA
IPC: C21C7/072
Filed: 1981-11-30
Abstract: PURPOSE:To obtain molten steel of particularly low content of oxygen by blowing an inert gas from the lower part and top of a refining vessel to substitute the atmosphere in the vessel with the inert gas. CONSTITUTION:If an inert gas such as Ar is blown into molten steel 2 from the bottom of a vessel 1 in the stage of refining of chromium-contg. molten steel or the like, the steel 2 is vigorously agitated to form many flow drops 21 which repeat ascending and descending. When an inert gas is blown there through a top blowing lance 3, the atmosphere 4 in the vessel 1 is substituted virtually thoroughly with the inert gas. Therefore, partial pressure of oxygen is made substantially zero. The surfaces of the flowing molten steel and the drops 21 are exposed to the fresh inert gas at all times. Thus, the oxygen in the molten steel dissipates in the form of mainly CO from the surfaces of the molten metal and the drops 21 into the atmosphere 4 and is carried away by the inerg gas, by which the disoxidation a high degree is realized.

Filed: 1994-08-16
Abstract: PURPOSE: To provide a remote controller which can be handled conveniently and can prevent its presence from becoming obscure by forming the controller in a specific size and shape so that the user of the controller may easily hold and grasp in his hand. CONSTITUTION: A remote commander 10 is formed in such a way that the width of the commander 10 becomes broader as going toward its upper end 12 and narrower as going toward its bottom end 14. Since the commander 10 is formed in such a shape, the user of the commander 10 can easily grasp the commander 10. In addition, since the commander 10 has a flat bottom face, the remote commander 10 can be put on a flat surface 16 in an upright state. The flat bottom section can be attached rotatably to the main body of the commander 10 so that the bottom section may be non-rotated and may function as a function selecting switch. The function selecting switch 32 allows the selection of a device to be controlled and, when a numeric key pad 22 is operated by the user, a signal to be transmitted is decided. Thus an appropriate control signal is transmitted to the device to be controlled.

Abstract: PURPOSE:To improve strength and ductility by conveying, in an unconcentrical ring state, a hot rolled carbon steel wire rod finished at specific high temp., holding it at high temp., and subjecting it to cooling down to specific temp. by means of air-water mist spray and then to controlled cooling by means of warm water. CONSTITUTION:A hot rolled carbon steel wire rod 1 rolled at 980-1100 deg.C by a finish rolling mill 2 is coiled by a coiler 3 at the same temp. This wire rod 1 is moved onto a roller conveyer 4 and held at high temp. for 3-15sec via a heat holding cover 5 while being conveyed in an unconcentrical ring state, by which crystalline grains are grown. Subsequently, the wire rod 1 is passed through an air-water mist spray 6 and cooled down to 850-750 deg.C in 5-17sec. At this time, it is preferable to regulate an air-water mist 10 so that the wire rod 1 can be conveyed while controlling the temp. difference between the central part of the coil and both ends to a value in the range of 0 to 40 deg.C. Subsequently, the wire rod 1 is passed through a warm water tank 12 and subjected to controlled cooling by means of warm water 11 in the range between 80 deg.C and boiled state, by which pearlite transformation is done over the whole length. By this method, the hot rolled carbon steel wire rod having high strength and high ductility can be obtained.
