Title: Oscillation circuit and its adjustment method
Inventor: TATEUCHI TSUGUJI
IPC: H03L7/00
Filed: 1988-06-01
Abstract: PURPOSE:To attain large scale circuit integration for an oscillation circuit of lots of circuits by inputting two signals (clock signal and shift clock signal) in common to plural oscillation circuits and holding a count enable signal by holding circuits connecting in multi-stage. CONSTITUTION:Count enable circuits 19 transfer a count enable signal sequentially from the front stage to the post stage in response to a shift clock signal inputted externally through the series connection of stages. While the count enable signal is inputted to the count enable circuit 19 and the count is permitted, a counting circuit 13 counts a clock pulse, the count is converted into a voltage by a digital-analog converting circuit 12 and the voltage controls the oscillating frequency of a voltage controlled oscillation circuit 11. Thus, the oscillating frequency of lots of VCOs is adjusted. Then lots of circuits are easily subject to large scale integration.

Title: Method and device for reforming refining slag
Inventor: SUZUKI MIKIO
IPC: C21C5/28
Filed: 1991-06-04
Abstract: PURPOSE:To recover slag having a low P2O5 content and reusability by inserting a cooling body into molten slag having a high P2O5 content and separating the slag having much P2O5 content, stuck to the cooling body and solidified. CONSTITUTION:In the slug at the time of executing pre-phosphorizing refining to molten iron or the slag at the time of executing steelmaking refining with a converter, as P2O5 is concentrated in dicalcium silicate (2CaO.SiO2) composition, these molten slags 3 are charged into a vessel 1 composed of steel-made outer plate 5 lines with graphite lining 7 and refractory 6. The metal-made flat plate-like cooling body 2 having water supplying/draining part 9, is dipped into the molten slag 3 and the slag is cooled with circulating flow of the cooling water and the dicalcium silicate phase 4 having high P2O5 and high m.p. is stuck to the periphery of the cooling body and solidified and taken out from the molten slag 3. This treatment is repeated and the P2O5 content in the remaining molten slag 3 is reduced and the slag having high P2O5 content is utilized as phosphatic fertilizer.

Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To structure a new system which can be constituted at a low cost and can use a bus efficiently by connecting each bus slave to one of buses which has corresponding transfer capability and connecting bus masters directly to the address buses and data buses of the respective buses. SOLUTION: The respective bus slaves 20 and 21 are connected to the buses 10 and 11 which have corresponding transfer capability or operation speeds corresponding to response speeds. The bus masters 1 and 2 are connected directly to the address buses and data buses of the buses 10 and 11. Consequently, a decrease in the use efficiency of the buses 10 and 11 due to the coexistence of the bus slaves 20 and 21 differing in data transfer capability is prevented to actualize the efficient use of the buses 10 and 11. Further, the problem that the data transfer width of the bus 10 with high transfer capability is consumed by the bus 11 with low transfer capability in hierarchical bus system is solved.

Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a control device for tilling height capable of lowering a tiller from a high position to a height of tilling depth control based on a laser beam rapidly and without causing shock. SOLUTION: An automatic control system for lifting and lowering a tiller 9 is constituted so as to pass a standard light L from a sending part T on the ground into a target incidence position at the middle position in the vertical direction of a receiving part S attached to the tiller 9. When the tiller 9 is dropped from an upper limit to a height of an automatic control, the tiller is lowered at a high speed while reducing a speed until the standard light L is received by the receiving part S. After receiving the light, the tiller continues dropping while further reducing the speed.  The dropping speed when the tiller is lowered sets a control operation for continuing the drop of the tiller 9 at a speed for an automatic control based on an incidence position of the standard light L against the receiving part S at a timing coincident with the dropping speed for an automatic control assumed based on the incidence position of the standard light L based on the receiving part S.

Abstract: PURPOSE:To obtain a reagent exhibiting specific agglutination reaction of high sensitivity by sensitizing an antibody (antigen) with the latex obtd. by polymerizing styrene by the use of a water soluble radical initiator in the presence of a silicic acid anhydride of ultrafine particles then treating the same with an antibody (antigen)-contg. serum. CONSTITUTION:A silicic acid anhydride of ultrafine particles of about 5-50mmu grain sizes (''Aerosil '': Product of Nihon Aerosil Co., Ltd., or the like) is dispersed in water, and strene is polymerized by using a water soluble radical initiator such as K2S2O7 or the like in water, whereby latex of small variance in grain sizes of about 0.384mu average grain sizes is prepd. This latex is sensitized with an antibody (or antigen) at 7-8.6pH. A serum contg. an antibody (antigen) is further added to the sensitized latex and these are stirred for a short time, after which the serum treated latex is again suspended, whereby a latex reagent is prepd. When the resultant reagent is caused to react with a specimen contg. an antigen (an antibody when the reagent is sensitized with the antigen), it makes specific agglutination reaction, and the antigen is detected without the disturbance by the other protein or the like in the specimen and with high sensitivity. In this way, this reagent is adapted for detection of hepatitis B virus and the like.

Title: Groove cover support device for groove block
Inventor: TODA EIZO
IPC: E03F5/04
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a colliding sound with an inside surface of a groove block without tilting in the concrete groove block even when a metallic groove cover receives an unbalanced load by the passing of an automobile. SOLUTION: Mutually opposing cover support surfaces 6, 6 in a groove opening 3 of a groove block 1 are respectively extended inward in a downward inclined shape from the lower end of an inside surface 5 to present an upward expanding state. While, taper surfaces 10f, 10f abutting to the cover support surfaces 6, 6 are formed on the respective outside lower ends of both leg parts 10, 10 of a groove cover 2, and the mutual inclined faces 10f, 10f of both leg parts 10, 10 present a downward narrowing state. Thus, even when a slight dimensional error is caused between a dimension in the groove opening 3 of the groove block 1 and both leg parts 10, 10 of the groove cover 2, the groove cover 2 can be supported in the groove block 1 without looseness.  Rotation preventive projections 18 are respectively arranged in both leg parts 10, 10 of the groove cover 2, and these are engaged in contact with a step part 7 of the groove block 1. Thus, the groove cover 2 does not incline and rotate even when an unbalanced load is applied by the passing of an automobile to prevent an end part of the groove cover 2 from colliding with the inside surface 5 of the groove block 1.
