Abstract: PROBLEM TO BE SOLVED: To improve formability, impact resistance, amounts of work hardening and baking hardening, and a balance between strength and elongation by providing a specific composition containing C, Si, Mn, and Cr, also providing a structure where primary phase is composed of pro-eutectoid ferrite and secondary phase is composed of martensite, acicular ferrite, and retained austenite, and regulating the crystalline grain size of pro-eutectoid ferrite to a specific value or below. SOLUTION: This steel sheet has a composition consisting of, by mass, 0.05-0.40% C, 1.0-3.0% Si, 0.6-3.0% Mn, 0.2-2.0% Cr, and the balance essentially Fe, and the crystalline grain size of pro-eutectoid ferrite is regulated to <=5 μm. A slab having the above composition is roughed, and finish rolling is finished at 780-980 deg.C while regulating the draft at the final pass to >=15%, followed by cooling down to 620-780 deg.C. Subsequently, the resultant plate is cooled down to 350-500 deg.C by isothermal holding or slow cooling treatment, coiled, and then cooled down to <=300 deg.C at (10 to 100) deg.C/h cooling rate. By this method, the steel plate can be produced.

Title: Data reception circuit
Inventor: OKADA AKIHIRO
Filed: 1985-07-31
Abstract: PURPOSE:To attain high throughput and high reliability and to reduce the circuit scale by outputting parallel information data appearing at the 2nd predetermined shift location group of a shift means in response to a predetermined comparison result output when it is generated. CONSTITUTION:Since an 8-bit parallel information data is set to a flip-flop 24 after a comparison result output is given at first, there is a sufficient time margin and high speed discrimination of a high speed data is attained. The extraction of the information in the unit of 8-bit is repeated for a predetermined number of times and after it is finished, a clear signal is generated on a line 18 to reset registers 10-14 and flip-flops 20-24 to the initial state and flip-flops 38, 40 are reset. Even when shift-in of a serial data to the shift registers 10-14 is generated, if the coincidence with an address data set to an address set switch 32 does not exist, no output from a AND gate 45 exists and no information data is extracted. Thus, the improvement of the throughput is progressed.

Title: Interpolation circuit
Inventor: NAKAI NOBUO
IPC: G11B20/18
Filed: 1983-09-16
Abstract: PURPOSE:To reduce the scale of an interpolation circuit by using a 1-bit adder to perform interpolation after applying the serial conversion to all data. CONSTITUTION:The input data (a) of a word and 16 bits having a separated error flag EF is supplied to a shift register 1 containing a synchronizing load of 16 bits. Then the register 1 converts the data (a) into the serial data through the LSB side. At the same time, the flag EF corresponding to the data (a) of a word is latched by a 1-bit latch circuit 10. In case the data (a) has no flag EF, the data (a) is sent to a 34-bit shift register 3 in the next timing. In this case, ''0'' is added by a bit as a dummy data by the 17th clock pulse. While if the flag EF is attached to the data (a), the EF held by the circuit 10 for a time interval of a word. Thus a 1-bit multiplexer 2 selects the output of the register 3.

Then a surfactant such as polyethylene glycol alkyl ether is added in an amount of 40wt.% based on the silicon alkoxide to advance the hydrolysis. At this time, the hydrolysis is carried out so that the pH of the hydrolyzing agent such as hydrochloric acid is kept at 2 to 6. Then the reaction mixture is condensed by dehydration to form a gel of 2 to 30CP viscosity. The gel is dropped on the base which is rotating at 1,000 to 3,000rpm to form a thin film on the base. Finally the thin film is dried at 60 to 90 deg.C to give an amorphous thin film having a high transparency and nonlinear optical effects.

Filed: 1982-09-29
Abstract: PURPOSE:To prevent a casing from vibrating due to its thermal deformation and reduce the loss of energy, by defining the cross-sectional shape of the inner surface of a packing as two arcs which are symmetric with each other as to a vertical axis extending on the center of a rotary shaft at a standstill and are coupled to each other as a closed curve. CONSTITUTION:The cross-sectional shape of the inner surface of a packing 12 is defined as two arcs nearly symmetric with each other as to a vertical axis X-X and coupled to each other as a closed curve, so that the vertical gap is larger than the horizontal gap. Wedge-shaped portions are provided inside the meeting points of the two arcs so that the resistance to the flow in the portions is higher than that in other regions. As a result, the leak of steam is diminished to provide a pressure distribution nearly symmetric in the circumferential direction, to prevent a turbine casing from vibrating due to its forward or backward stoop deformation or the like. Because of the symmetric distribution of pressure, a vibration due to a steam whirl is also prevented. Because of the reduction of the leak of steam, the loss of energy is decreased to keep the efficiency of a turbine from falling.
