Patent JP-H03246624-A (JP)
Title: Characteristic discriminator
Inventor: HARADA NORIO
IPC: G06F9/44
Filed: 1990-02-23
Abstract: PURPOSE:To simply output the degree of an input belonging to a certain characteristic without requiring statistic processing or the like by providing the characteristic deciding device with a means for calculating a characteristic function value based upon an input value. CONSTITUTION:The characteristic deciding device is constituted of an input means 1, a calculating means 2 for calculating a characteristic function value based upon an input value (x) and an output means 3. The means 2 calculates the sum of the combinations of input values (x) for the characteristics of each single attribute based upon a prescribed theorem relating to the standard type of characteristic functions, calculates the applied non-negative integer width of the calculated value and then calculates a characteristic function value by the addition/subtraction of products of these calculated values and the coefficient of the standard type of characteristic functions. Consequently, the degree of an optional input value belonging to a certain characteristic can be simply outputted as a character function result without executing the statistic processing or the like of the input value.

IPC: G03G15/00
Filed: 1978-04-15
Abstract: PURPOSE: To prevent paper clogging or deviation of recording images by providing one set of paper detecting means in the relation of detecting the arrival of recording paper and detecting the arrival of the recording paper heading toward dischage line after having passed the transfer part in the front stage of a transfer charger.  
     CONSTITUTION: A reflecting face 15 of a reflectance lower than that of recording paper is formed on a guide plate which guides the recording paper PR from a resist roller 13 to the transfer part. When the recording paper does not exist, the light of a light emitting element 50 2  reflects on the reflecting face 51, escapes to the underside of a guide roller 29 and enters a photoelectric transducer 50 1 . When the recording paper is sent from the resist roller 13 and its leading end comes onto the reflecting face 51, the quantity of light received in the photoelectric transducer 50 1  becomes maximum, whereby the arrival of the paper is detected. When the leading end of the paper passes the underside of the transfer charger 14 and guide roller and is changed of its direction so as to wind up on the guide roller 29, the optical path from the reflecting face 51 is cut off and the quantity of light received in the photoelectric transducer 50 1  becomes minimum, thus the discharge of the paper from the transfer part is detected.

Abstract: PURPOSE:To realize the effective control of a plant, by identifying successively the models of the plant with a one-to-integer control period and then using these models to identify a model which has its transition of state with the same period as the control period. CONSTITUTION:A turbine steam current demand FMSD given from a generator output controller controls a primary steam control valve 416 via a turbine controller 301.

These obtained moduli are given to an optimum control system 100 incorporated to model. The system 100 defines the modulus LDR as the disturbance and then the primary steam temperature  deviation TMSE, the modulus TWWR and the reheated steam temperature deviation TRSE given from the controller 200 as the control quantity. Thus the models combining the disturbance generating processes and controlled systems are successively identified, and the controlled system is controlled by means of a secondary type evaluation function.

Title: Blow nozzle for molding machine of cold box type mold
Inventor: KAWAI KIYOMITSU
IPC: B22C15/24
Filed: 1980-04-04
Abstract: PURPOSE:To prevent the formation of defects such as stickers in a mold by using a blow nozzle of a specific shape to a molding machine of cold box type mold. CONSTITUTION:A nozzle 1 made of a flexible material is mounted to a blow plate 10 of a cold box type mold molding machine using wet sand by means of a nozzle holder 2 made of steel. A baffle bar 3 provided with a circular conical baffle part 4 at the tip at the axial center in the central part of the nozzle 1 is fitted and fixed by means of a baffle bar root part 5 to the nozzle holder 2. At the time when the wet sand blown through the hollow part formed by the baffle bar 3 in the nozzle 1 from the sand box is ejected into the metal mold cavity from the end part of the nozzle 1, it is ejected in a diagonal direction by the slope of the circular conical baffle part 4. Hence, the angle of injection spreads to a wide range of 360 deg. and this prevents the wet sand from vigorously colliding against only the specified place of the inside surface of the die and peeling the mold releasing powder, thereby preventing the formation of stickers in that part.

Title: Serration shaft
Inventor: UEDA YUJI
IPC: H01C10/00
Filed: 1991-03-11
Abstract: PURPOSE:To eliminate an excess stress to a body side in which a serration shaft is mounted. CONSTITUTION:A serration shaft 1 to be used as a coupling shaft is made of resin, its head side is formed as a bottomed hollow cylinder, divided into one half 2 and the other half 3 by a split groove 21, and both are coupled by a bottom 4. Serration teeth 7, 8 are respectively formed on one half 2 and the other half 3. Since the groove 21 is wide, the teeth 7, 8 formed on the one and the other halves 2, 3 are reduced, a contact area of them with other component to be engaged therewith is largely reduced. Thus, since the other component can be simply mounted when the other component is mounted on the shaft, a stress to a movable shaft coupled to the serration shaft can be reduced at the time of mounting.

Filed: 1984-03-09
Abstract: PURPOSE:To obtain a sound joint free from defect by detecting and calculating welding current and a feeding speed of consumable electrode to determine the length of protrusion of the electrode, and controlling the position of a torch based on the pattern of change. CONSTITUTION:Average welding current is determined by a current detector 24 and an amplifier 29, and the effective value of welding current is determined by the detector 24 and the amplifier 29. The relation between the average value and the effective value of welding current and the wire feeding speed is given by an approximate formula. The length of protrusion of the wire is determined from a program of the approximate formula by a digital electronic computer 36. The average value of the length of protrusion of the wire for one cycle is compared with a set value of a setting device 30, and outputted to a controlling device 7, and each shaft of a robot is controlled to conform the average value with the set value. By this method, the width of oscillation follows up variation of groove interval automatically, and at the same time, follows the weld line automatically. Accordingly, a joint free from defect can be obtained.
