Inventor: TANIGUCHI YASUNORI
IPC: B41J29/48
Filed: 1994-03-10
Abstract: PURPOSE:To reset a carriage in a short time in the carriage resetting system of a printer. CONSTITUTION:A reset processing part 2 moves a carriage 9 in a predetermined direction in order to reset the position of the carriage 9 holding a printing head 10 and subsequently detects the presence of a reset error. The reset processing part 2 applies first force having a predetermined magnitude moving the carriage 9 in the predetermined direction to the carriage 9 when the change of the moving speed of the carriage 9 moved in the predetermined direction for the sake of resetting is large and subsequently applies second force larger than the first force to the carriage 9 in the same direction as the first force and emits a reset error when the position of the carriage 9 is changed by the second force.

Title: Method of forming recessed and protruded pattern on fibrous board
Inventor: FUKATSU MIKIO
IPC: B29C33/00
Filed: 1979-04-02
Abstract: PURPOSE: To efficiently form recessed and protruded pattern of sufficient solid appearance, by hotpressing a sheathing insulation board and by forming the pattern on the board as board treating asphalt is fluid.  
     CONSTITUTION: While or after a sheathing insulation board is hotpressed, this board is treated with asphalt. A recessed and protruded pattern is made on the board as the asphalt is fluid. For example, a synthetic resin paint is coated on the surface of a sheathing insulation board complying with the JISA5,905 standard and is dried. The board is then inserted in between metal molds so that the board is hotpressed at a temperature of 20°C under pressure of 20W100kg/cm 2  for 5W10 seconds. As a result, blown asphalt in the board is molten and fluidized and a recessed and protruded pattern corresponding to that on the surface of the upper metal mold is made on the board.

Title: Method for deciding life of fixing device
Inventor: ISHINO MASAHIRO
IPC: G03G15/20
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a method for deciding the life of a fixing device, capable of more accurately judging the life of the fixing device than in a conventional method. SOLUTION: The life of the fixing device is decided based on the accumulation volume of toner fixed by the fixing device. The accumulation volume of the toner fixed by the fixing device is obtained from the cumulative toner replenishment time of a cartridge for replenishing the toner to a developing device, the pixel accumulation value of a printed image, or the number of times of replacing the cartridge for replenishing the toner to the developing device. The cumulative toner replenishment time (t) of the cartridge is obtained at steps S3 and S4, the time (t) is compared with a 1st reference value (t0) at a step S5, and in the case the judgment (t>=t0) is established, a display for urging a user to replace the fixing unit is imparted at a step S6. Next, when the time (t) reaches a 2nd reference value (t0'), the operation of the device is forcibly stopped at a step S8.

Title: Vortex flow wet scrubber and coating spray booth equipped therewith
Inventor: YAMAZAKI MAKOTO
IPC: B05B15/12
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To ensure the uniform inflow of liquid into an acceleration cone by providing a height adjusting member as an annular member to be fitted to the peripheral edge part of an inlet of the acceleration cone which adjusts the height of an inflow region of the liquid into the acceleration cone to the same level height across the entire periphery edge of the inlet. SOLUTION: The height adjusting member 7 is a separate strip annular member from the body of the wet scrubber and is fitted to the peripheral edge part of an inlet 25 of the wet scrubber. The height adjusting member 7 is of a more lightweight structure, so that when it is fitted to an acceleration cone 2, the height adjusting member 7 can be easily and simply adjusted so as to make the level height of an inflow region of water (p) into the acceleration cone 2 the same across the entire circumference of an inlet peripheral edge 27 of the acceleration cone 2. Consequently, when the wet scrubber is fitted to the flow plate 17 of a coating spray booth, the wet scrubber can be easily fixed in such a position that the inlet peripheral edge 27 of the acceleration cone 2 is retained at the same level height across the entire circumference.

Filed: 1988-02-23
Abstract: PURPOSE:To accomplish long lifetime under high current density operation by forming a scandium oxide layer of 10mum thick or less previously on a base, and covering it with an electron emitting substance layer, which contains chiefly oxidated alkali earth metal incl. barium and also scandium oxide in specific wt.%. CONSTITUTION:A scandium oxide layer 13 of 10mum thick or less is formed on a base 1 containing nickel as main component, and thereover an electron emitting substance layer 2a is put, which contains chiefly oxidated alkali earth metal 11 incl. at least barium and also a scandium oxide layer 12 in 0.1-20wt.%. This prevents oxidating reaction of the base 1 likely to occur when carbonates of alkali earth metal are decomposed at the time of activation of the electron emitting substance layer 2a, and concentrated formation of an intermediate layer consisting of complex oxides in the neighborhood of the interface between base 1 and electron emitting substance layer 2a due to reductive elements included in the base 1 will be prevented. This provides an emission characteristic stable for a long time under high current density operation.

Title: Dynamic balance device for machine press
Inventor: OTONASHI KENSUKE
IPC: B30B15/00
Filed: 1988-02-25
Abstract: PURPOSE:To prevent the vibration of a press and to reduce the equipment cost by arranging the centroid of a lever in opposition by interposing a crankshaft center for a connection rod in the link and lever converting the rotation of a main gear into an ununiform rotation. CONSTITUTION:One end of a link 10 is fitted by a pin 9 to the inner peripheral part of the main gear 8 of a press and the other end is pivotally fitted by a pin 13 to the lever 12 of the crank shaft 11 having a center shaft at an eccentric position o'. In this case a lever 12 is formed by arranging it at the side opposing 180 deg. to a connection rod 14 so as to serve for a counter balancer as well and the weights of the connection rod 14 and lever 12 are balanced by interposing the center of the crank shaft 11. In case of a slide being driven the lever 12 acts to cancel the vibromotive force by the rotary inertia of the connection rod 14. The vibration of the press is thus prevented. The equipment cost of the press is reduced because a counterweight, etc., are not provided separately.

Abstract: PURPOSE: To decrease the amount of O 2  in an electric furnace, and increase the yield of the molten iron in the electric furnace by allowing the carbonaceous material which has been imperfectly burned to CO to exist in the electric furnace.  
     CONSTITUTION: Grained coal and a small amount of O 2  are blown into a combustion chamber 6 and the grained coal is imperfectly burned to the state of CO, after which it is removed 7 of ash and is blown into an electric furnace 1.
