Title: Production of iron oxide from waste hydrochloric acid liquor for pickling
Inventor: TEJIMA YASUTAKA
IPC: C01G49/02
Filed: 1982-10-19
Abstract: PURPOSE:To obtain economically a low-Si iron oxide which is a raw material for high- class ferrite, by roasting or crystallizing a waste liquor obtained by ultrafiltering a waste liquor after pickling a steel material with hydrochloric acid. CONSTITUTION:A waste liquor produced by acid washing of a steel material with hydrochloric acid such as steel plates, molds, rods, wire materials, etc. with the hydrochloric acid is ultrafiltered to reduce the SiO2 content to 2-10ppm. The resultant ultrafiltrate is then roasted and crystallized to give the aimed low-Si iron oxide. In a schematic drawing of an example, the above-mentioned waste liquor of acid washing charged into a waste liquor tank 1 is passed through a preliminary filtration apparatus 3 to a module 4 consisting of ultrafiltration membranes. The resultant ultrafiltrate obtd. in the filtration apparatus 3 is passed through a solenoid valve 5 to a filtrate tank 6. The concentrated solution is then returned to the waste liquor tank 1 and recirculated therethrough. The ultrafiltrate is suitably taken out of an extraction pipe 7, fed to a roasting apparatus and passed through a roasting stage to prepare iron oxide. The back washing necessary for the ultrafiltration is carried out by using a counterflow pump 8 and a check valve 9.

Title: Rolling method of shape steel
Inventor: MATSUMURO TOMOMI
IPC: B21B1/088
Filed: 1980-12-23
Abstract: PURPOSE:To make the stripping of a material to be rolled during caliber rolling easy and to make the material rollable in a fallen down state by screwing down a bloom or billet to an (approximately) square molding angle, and further forming notches or recesses symmetrically on the four faces thereof. CONSTITUTION:A bloom or billet is rolled for a number of passes whereby it is molded to a square molding angle or shape nearly a square, and its four faces 1a, 1b, 1c, 1d are formed with notches or recesses 2 symmetrically vertically and laterally. At this time, the notches 2 are first formed on the faces 1a, 1c by upper, lower rolls, after which the bloom or billet is turned laterally 90 deg. and the notches 2 are formed on the faces 1b, 1d. Then, it is caliber-rolled in accordance with conventional methods. If shape steel is rolled in this way, there is no need for correcting the same in spite of turning laterally during the transfer to the caliber rolling, the side pressure of the caliber is reduced and the material to be rolled is stripped easily from the caliber.

Title: Ball for pinball game
Inventor: YASU TOSHINORI
IPC: A63F7/40
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To reduce the damage of a ball for pinball game, and suppress the volume reduction due to wear by coating the surface of the ball for pinball game with a resin. SOLUTION: Balls for pinball game which have been used for a certain period of time, are washed by ultrasonic waves by placing them in a container in which a solvent such as acetone, is placed. After drying them, the balls are moved in a passage made of teflon, etc., for resin application, while making them rotate, and a thermosetting resin 3 is jetted to the balls several times, and a thin and uniform film is formed, and the film is hardened in a drying oven. By doing so, the resin 3 enters flaws K and fine unevennesses P on the surface of the balls 1 for pinball game. Also, by the thermally hardened resin 3, the surface of the ball 1 for pinball game becomes hard and smooth, and the elasticity becomes higher than that of a metal being used.  Therefore, flaws become hard to generate by collisions between the balls 1 for pinball game with each other, or between the balls 1 and nails, and wear can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To realize a high productivity without influence of job interruption by predicting whether or not the image data output is interrupted halfway according to the detected resource state and suspending the output of the image data with the interruption prediction. SOLUTION: In outputting image data received by a facsimile or image data inputted from a computer by scanning, interruption due to insufficiency of the resource necessary for the output is predicted so as not to ruin the productivity. A digital copying machine main body 11 connected with an image input and output part 105 monitors the state of each resource by a remaining sheet amount sensor, a stable remaining amount sensor, or the like, in each part for judging whether or not the output is interrupted halfway. In the case it is judged to be interrupted, input of a command on whether or not it is outputted forcibly is awaited. In the case of no input after passage of a predetermined time, it is reregistered as an output reserved job at the last of the queue.

Abstract: PURPOSE:To eliminate an inconvenience due to a duplicating transfer or the deficiency of a capacity by delivering required information relating to the mutual file at the initial time of a transfer, deciding the propriety of the transfer for every type of data and repeating the transfer only the possible data on all the types. CONSTITUTION:At the time of generating a data transfer request, a self-file using status is added to a data transfer start request telegraphic message and transferred to a host side from a terminal side. In the host side, a data transfer start response telegraphic message to which the data transferring file using status is added is transferred to the terminal. A terminal operator selects the transfer file and requests the transfer request for a file unit to the host side. In the host side, the propriety of the transfer is decided as one processing of the start processing for the file unit. When a result is impossible, the transfer request of a relevant file is rejected, when it is possible, the data stored in a center device is taken out to transfer the data between the center device and the terminal, consequently, the data is stored in the disk or the like of the terminal side. This data transfer is repeated until the completion of all the files.

Title: Digital ground fault distance relay
Inventor: FUJII KYUICHI
IPC: H02H3/40
Filed: 1988-07-25
Abstract: PURPOSE:To reduce processing load of a CPU by employing and identical calculation process of the amount of input current upto the distance element in each stage and compensating zero-phase current of adjoining line corresponding to the position of fault point. CONSTITUTION:Zero-phase current I01 in one line is multiplied by K01 through a multiplier means 1 while zero-phase current I02 in an adjoining line is multiplied by K02 through a multiplier means 2. A judging means 3 employs K1, K2 as constants and closes a switch 13 when the formula (1) is satisfied while provides an opening signal when the formula (1) is not satisfied. Consequently, it is determined whether information of the adjoining line is added to the input of an adder 4. Since identical inputs are fed to all relays in this system, calculation is simplified when compared with a conventional system where information of adjoining line is fed to the input of 44GX1, 44GX2 relays but not fed to the input of a 44GX3 relay.

Abstract: PROBLEM TO BE SOLVED: To suppress the distortion of waveform of a reproducing signal caused by the fluidization of a recording film at the time of rewriting many times in the information recording method capable of recording information by irradiation of an energy beam. SOLUTION: By using a recording medium having a recording area 14 between dummy areas 15, 16 succeeded to a preformat area 10, information recording is performed by means of a signal adding a dummy signal to at least one signal before or after a recording information signal. Consequently, since the fluidization of a recording film at the time of rewriting many times is kept within a dummy area and does not affect the inside of an objective recording area, the objective recording information is surely reproduced.
