IPC: F23C10/18
Filed: 1981-01-19
Abstract: PURPOSE:To make fuel capable of complete combustion in an open tower part in a furnace in which powdered fuel is burnt on a fluidized bed by a method wherein the height of the open tower part is decided so that the remaining time of unburnt gas becomes equal or superior to the combustion completing time of the unburnt gas. CONSTITUTION:A porous plate 2 is arranged in the lower part of the fluidized bed furnace body 1. The fluidized bed 3 and an air chamber 4 are formed respectively on the upper part and on the lower part of the porous plate 2. Now, the speed at which waste gas G of fuel F burnt on the fluidized bed 3 rises in the open tower part 6 is controlled by the supply speed of fluidized air supplied from a blower 5 and the speed is considerably high, usually 5-10m/sec. On the other hand, the unburnt gas scattering in the open tower part 6 requires a combustion time of about 2sec. Therefore, the height H1 of the open tower part 6 is set within the range of about 15-20m and the remaining time of the unburnt gas in the open tower part 6 is to exceed about 2sec. Thus, the fuel F is burnt completely in the open tower part 6.

Title: Lead screw device for drive of reciprocative table
Inventor: MASUDA MASAMI
IPC: F16H25/24
Filed: 1983-01-18
Abstract: PURPOSE:To provide a lead screw device in simple construction and with excellent motion and location accuracies by using a lead screw made with smaller pitch than the dimension according to regular projection method and by installing this lead screw at the bearing while a tensile load is applied in the axial direction. CONSTITUTION:If a tensile load F is applied to a lead screw 1A, the elongation DELTAp between pitches caused thereby can be expressed as DELTAp=p.F/(A.E), where p is nominal pitch of lead screw, A is effective section area of lead screw and E is Young's coefficient of lead screw. Accordingly, if tensile load F is applied to the lead screw 1A by giving it a pitch smaller by DELTAp than the regular dimension, an eventual temp. rise of the lead screw 1A will only lead to reduction of tensile force, i.e. reduction of the internal force, not causing movement of the actual nut 4 position, to secure excellent motion and location accuracies.

Title: Man conveyer
Inventor: YOSHIKAWA TATSUYA
IPC: B66B29/00
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To provide high safety of passengers and prevention of damage to apparatuses by taking it as an abnormal condition if the speed of a stairway or a handrail has not reached prescribed reference speed even at required prescribed time for obtaining the prescribed speed after a stairway and handrail operating command is received. SOLUTION: When the operation of a man conveyer is started, a stairway speed detection device 16 and a handrail speed detection device 17 inputs the output signal of an operating signal generating means 18. A small computer 19 discriminates if detected stairway speed and handrail speed have reached the values higher than stall detection set speed at the time of the ordinary operation of the stairway 16 and the handrail speed detection device 17 and higher than preset first reference speed respectively. If it takes longer time than the time corresponding to the minimum first prescribed time to conduct ordinary start, it is taken as occurrence of an increase in starting resistance due to stuck brake lining or failure of a handrail drive part, consequently, the man conveyer is stopped.

Title: Scratch marker
Inventor: YONENAKA KAZUHISA
IPC: H01L21/66
Filed: 1987-01-13
Abstract: PURPOSE:To form a circular flaw, and to discriminate between nondefectives and defectives easily owning to a circular scratch mark by cutting a wafer, turning a cylindrical marker body. CONSTITUTION:A semiconductor wafer 3 is cut by a diamond chip 2 by rotating a marker body 1, and a circular scratch is shaped. The marker body 1 is pushed upward by the force of a spring 7 in the state in which no flaw is formed, and separated from the semiconductor wafer 3. A motor 4 is rotated at all times, the marker body 1 is lowered against the force of the spring 7 by a pusher 6 when the semiconductor wafer 3 reaches a position where the wafer must be flawed, and the semiconductor wafer 3 is cut. Consequently, the semiconductor wafer is cut by the revolution of a cylindrical marker, thus reducing a shock in the vertical direction applied to the wafer. The quantity of cutting can be increased by lengthening the time when the marker is pushed against the wafer, thus resulting in no trouble of the limit of the quantity of cutting, then stamping a deep scratch.
