Title: Process for pickling hot rolled steel belt
Inventor: KAIHARA RIICHI
IPC: C23G3/02
Filed: 1978-08-02
Abstract: PURPOSE:To subject the edge of a hot rolled steel belt to a mechanical grinding operation prior to the introduction of the same into a pickling tank thereby to reduce the piclking cost and improve the piclking efficiency. CONSTITUTION:The difference in the pickling ability between the edge part and central part of a hot rolled steel belt increases as the take-up temperature increases. Accordingly, contribution due to the improvement in the pickling ability at the central part of said steel belt becomes remarkable in a high-temperature take-up material. Even in the high-temperature take-up material the pickling ability at the central part is not so different from that in the ordinary take-up material. Accordingly, prior to the introduction into the piclking tank of the steel belt mechanical grinding is applied thereto by means of a grain-containg nylon bruch, a hard metal wire brush or the like in the length of 50 to 200 mm at one side of the edge part under sufficient grinding allowance. The grinding allowance is determined to such a such a degree that an oxidized film remains, which requires 0.8 to 2.0 times, preferably 1.0 to 1.3 times, necessary pickling time based on the necessary pickling time at the central part of said steel belt.

Title: Method for inputting image information
Inventor: SHIJO KUNIO
IPC: H04N1/21
Filed: 1986-04-23
Abstract: PURPOSE:To eliminate a line memory and to extremely simplify the constitution of a circuit by inputting image information directly to a memory controlled by a CPU bus. CONSTITUTION:During the output of invalid data from a reading element 41, a CPU 40 executes a dummy instruction to adjust a period. After the execution of the instruction, the CPU 40 inputs effective image information outputted from the element 41 regularly and directly to the memory 43 controlled by the CPU BUS. At that time, the CPU 40 executes the succeeding dummy instruction to make the processing time, i.e., an input period Tb, coincide with the time required for shifting the image information in a shift register 50 by the bit width of a data bus 44. Consequently, the transfer timing of the image information outputted from a reading element control port 54 and the element 41 is synchronized with the input timing of the CPU 40 and the image information is directly inputted and stored to/in the memory 43 based on the synchronized timing.

Abstract: PURPOSE: To enhance the measuring accuracy by inductively coupling the ground measuring facilities, which have guide lines extended in a speed measuring section along the running passage of a moving body and intersecting at a preset spacing, and the antenna of a moving body with the use of frequencies having a preset relationship.  
     CONSTITUTION: The signals of two frequencies having a relationship of f 2 =mf 1 / (m-1) (wherein m stands for an integer equal to or larger than 2) are inductively transmitted from a transmitter 10 at a moving body side through guide lines 1 and 2 to a ground station. Since the guide line 1 intersects at two fixed points S 1  and S 2 , the phase of the input signal waves to a speed meter 7 is inverted 180 degrees each time the position of an antenna 8 passes through the points S 1  and S 2 . This inversion does not take place at the guide line 2. Then, the f 2  and f 1  wave components are extracted at BPFs 11 and 12 and made to have a preset amplitude by ALs 13 and 14 so that they are made to have a relationship of 2f 1 =f 2  by a multiplier 15. Then, they are fed as reference phase waves to a phase discriminator 16. As a result, the counted value of a counter 19 is read out by a speed information output device 20 in accordance with that output so that the speed level of the moving body can be accurately determined.

Title: Fm modulating and demodulating circuit
Inventor: AKIYAMA RIYOUTA
IPC: H03L7/18
Filed: 1980-07-11
Abstract: PURPOSE:To improve an S/N ratio and to reduced distortions with simple constitution by applying a control voltage to a voltage-controlled oscillator via a distortion compensating circuit, composed of a diode and a resistance, in a circuit which uses a PLL. CONSTITUTION:In an FM modulating and an FM demodulating circuit, distortion compensating circuits CPS1 and CPS2 are connected between amplifiers AMP1 and AMP2, and voltage-controlled oscillators VCO1 and VCO2. The CPS1 and CPS2 are each composed of a parallel circuit of a diode and a resistance, and characteristics inverse of voltage frequency characteristics of the VCO1 and VCO2 are obtained by adjusting resistance values of them. Consequently, distortions due to the nonlinearity of the VCO1 and VCO2 are compensated and an S/N ratio is therefore improved by making the sensitivity of the VCO1 and VCO2 relatively small. In addition, distortions are reduced.
