Title: Production of high-chromium alloy steel
Inventor: YOSHIDA MASASHI
IPC: C21C7/00
Filed: 1985-11-02
Abstract: PURPOSE:To make blowing of steel of a wide range of Cr levels at a good yield of Cr by using a top and bottom blown refining furnace, controlling the flow rate of a bottom blowing gas and oxygen blowing rate from the upper part and quantitatively determining the cross relation between the latter and the transition of the concn. of Cr.C, then executing the blowing. CONSTITUTION:A steel bath of 1,600-1,800 deg.C is subjected to blowing at the flow rate of the bottom blowing gas controlled to >=0.06Nm<3>/min per ton of the molten steel and at the oxygen blowing rate from the upper part controlled to <=3.5 Ko2 (Nm<3>/min/ton of the molten steel) in the stage of producing a high-Cr alloy steel by a top and bottom blown refining method. The blowing is executed by controlling the oxygen blowing rate Ko2 in such a manner that the value of RIDAS expressed by the equation attains 15-30. In the equation, [%Cr], [%C] are respectively the concn. (wt%) of Cr and C in the steel bath. The blowing of the stainless steel in a wide range of Cr levels is thus executed at the good yield of Cr and alloy iron such as ferrosilicon and Al necessary for the reduction of the Cr oxide is reduced. The considerable reduction or elimination of the load of a finish decarburization stage is made possible.

Title: Sheet feeding mechanism
Inventor: MINAGAWA HIROYUKI
IPC: B65H3/06
Filed: 1989-09-21
Abstract: PURPOSE:To liberate a transport roller from excessive burden by forming a pick roller so as to have D profile, and mounting an idling disc having a little smaller dia. than the pick roller at either or both of its ends in such a way as rotatable on a drive shaft. CONSTITUTION:When the leading edge of a sheet for slip 11 transported by a pick roller 3 reaches a transport roller 5, the pick roller 3 transfers from the circumferential part 3A to a notch part 3B and separates from the sheet 11, which is instead contacted by an idling disc 6. Accordingly, the sheet 11 is liberated from the drive force given by the pick roller 3, and thereafter the transport is made by the transport roller 5. The pick roller 3 rotates until the notch part 3B becomes parallel with sheets 11 in a hopper 1, and the rotation of the drive shaft 2 due to external force is stopped when parallelism is attained, and then the pick roller 3 also stops rotating.

Title: Foul state discrimination device
Inventor: NAKAGAWA KAZUYO
IPC: G07D7/06
Filed: 1994-10-11
Abstract: PURPOSE: To provide a foul state discrimination device capable of always accurately discriminating a foul state without largely depending upon feature amount relating to a foul state used for learning. CONSTITUTION: Image data for an object P to be discriminated are inputted to an image input part 1 and a specific area extracting part 3 extracts image data in a specific area from the inputted image data. Feature amount extracting parts 5 to 8 extract physical feature amount from the extracted image data in the specific area. An average value calculating part 12 prepares leaning data by averaging respective extracted feature amounts in each foul state of the object P which is judged by a person. A discriminating part 9 is constituted of a neural network constructed based upon the prepared learning data and discriminates the foul state of the object P by evaluating respective extracted feature amounts.  An error calculating part 13 calculates an error between an output value from the discriminating part 9 and the foul state judged by the person at the time of inputting the leaning data and executes the leaning of the neural network until the error becomes a prescribed value.

Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To reduce noise to give no unpleasant feeling to an operator by preventing generation of alarm by interference alarming means when a structure on the side of a boom is in a retracted state. SOLUTION: Since a structure on the side of a boom which is in a retracted state, at the time of start of operation, is so close to a structure on the side of a vehicle that there is a danger of interference, posture detection means 20 detects it, and according thereto comparison means 26 determines that entering in an interference danger region stored in danger region storing means 25 is made, then a danger informing signal is output. In this condition, however, since a boom rest supports a lower surface of the boom, the retracted condition of the boom is detected by boom retract condition detection means 32 and a length detector 23 and the retracted condition of a platform is detected by a turning position detector 24.  Then, alarm generation preventing means 33 works when retract condition detection means 31 detects the retracted condition while the comparison means 26 outputs the danger informing signal prevents generation of alarm from interference alarm means 27. Similar operation is made when the structure on the side of boom is in the retracted posture in the case of retracting.

Title: Magnetic recording and reproducing device
Inventor: MITSUBE AKISHI
IPC: G11B15/48
Filed: 1994-10-12
Abstract: PURPOSE: To obtain a magnetic recorder with which electric power consumption and the load on a microprocessor are reduced. CONSTITUTION: The winding position of a tape is determined from the signals proportional to the respective rotating frequencies of a capstan motor 2, a supply reel 16 and a take-up reel 17. An LED (light emitting means) 18 for detecting the tape end and phototransistors (light detecting means) 19, 20 for detecting the tape end are made to effectively function only when the winding position of the tape exists near the tape end. As a result, the need for energizing the LED 18 for detecting the tape end and the phototransistors 19, 20 for detecting the tape end is eliminated unless the tape exists near the tape end. The electric power consumption required for detecting the tape end is thus drastically reduced.

Abstract: PURPOSE:To exactly adjust the position of a pickup in such a manner that the angle formed by the optical axis of the pickup and a data recording surface is maintained always constant with simple construction by vertically moving a guide shaft with a supporting part as a fulcrum. CONSTITUTION:The pickup 21 detects the inclination of the data recording surface 23a of an optical disk 23 in the radial direction and detects whether the angle formed by the optical axis of the pickup 21 and the data recording surface 23a is 90 deg. or not. A motor 33 is rotated to a prescribed amt. if the angle is not 90 deg.. The driving power of the motor 33 is transmitted to a circular cylindrical cam gear 29. An end part 25b is vertically moved and the guide shaft 25 oscillates around the supporting part 27a as the circular cylindrical cam gear 29 turns. The supported pickup 21 oscillates as well upon oscillation of the guide shaft 25. The position of the pickup is thus exactly adjusted until the angle formed by the optical axis of the pickup and the data recording surface of the optical disk is maintained always constant with the simple construction.
