Title: Method of operation control for sludge concentration tank
Inventor: SUGIURA KIYOSHI
IPC: C02F1/00
Filed: 1979-11-05
Abstract: PURPOSE: To enhance the economy and efficiency of the operation of a sludge concentration tank by a method wherein the change in the concentrating unit capacity is judged by measuring the time variation of the level of the sludge concentration tank, and on this basis, the sludge treatment equipment operation is controlled.  
     CONSTITUTION: From top to bottom of the secondary sludge concentration tank 20, detection levels L 1 , L 2 , L 3  are installed for the operational control of the secondary concentration unit; and detection levels L 4 , L 5 , for the sludge treatment equipment. The level L 4  is the lowest level at which it is possible to supply sludge to the freeze- melt tank 18 of the equipment, and specifies the permission of sludge supply. To detect each such level, the use of electrode-type liquid-level detector is preferable. If the sludge level is lower than the L 4 , the time needed for the level to reach L 4  is measured, and that time is used as the judgement of the change in the capacity of the secondary concentration unit. According to this judgement, sludge feed to the freeze-melt tank 18 is continued or waited for. The level L 5  specifies the lower limit below which the sludge pump 22 running is stopped and alarm is generated.

Title: Gear slip-off preventing mechanism for transmission
Inventor: SHIMOYASU KINYA
IPC: F16D23/06
Filed: 1994-05-31
Abstract: PURPOSE:To surely prevent the slip-off of a sleeve which is easily slipped off, by forming a stage part only on the male spline of a hub at the position in one revolution direction where the sleeve of a gear slip-off preventing mechanism in a transmission is easily slipped off and by putting the rear end of the sleeve into contact with the stage part. CONSTITUTION:On a main shaft 8, a hub 5 having a male spline 5a formed on the outer periphery is fixed, and a sleeve 4 is spline-fitted in a slidable manner in the axial direction with the male spline 5. On both the sides of the hub 5, main gears 9 and 10 having each different diameter are fitted in a turnable manner with the main shaft 8, and the slip-off of the sleeve 4 is prevented by attaching the rear end of the sleeve 4 with the stage parts 5b and 5c formed on the male spline 5a of the hub 5. In this case, the stage parts 5b and 5c formed on the hub 5 are formed only at the position in one revolution direction where the slip-off of the sleeve 4 is easily caused. Accordingly, the excellent operation performance is secured, keeping the operating force of a shaft lever constant, for all the main gears 9 and 10.

Title: Illuminating device for micro camera
Inventor: OKABAYASHI HIROYUKI
IPC: G03B27/32
Filed: 1985-07-01
Abstract: PURPOSE:To equalize the illumination distribution by providing a louver in the forward direction of the illuminating light source and constituting the louver blade arranged in the vicinity of the irradiating axis line of the illuminating light source wider than other louver blade. CONSTITUTION:The device is composed of a light source 8 for illumination supported at the inside of a reflector 7 and a louver 9 fitted freely detachably into the opening part of the reflector 7. A wide louver blade 20 arranged near an irradiating axis line LO is extended almost in parallel to the axis line LO, and therefore, the light flux vignetted by the blade 20 is very little. The light flux interrupted by the blade 20 at the position away from the shaft line LO comes to be much compared with the case when it is a narrow louver blade 10. As a result, the light flux to reach near the central part on the original surface which is the illuminating surface comes to be little, the illumination of the part is low, and therefore, the illumination of the whole of the original surface can be equalized.

Title: Automatic plate thickness controlling method for rolling machine whose speed is accelerated/decelerated
Inventor: INAMURA KAZUMI
IPC: B21B37/18
Filed: 1992-06-03
Abstract: PURPOSE:To improve the precision of plate thickness when rolling speed is accelerated or decelerated by changing rolling reduction by increasing or reducing the controlling constant for correcting the oil film thickness according to the direction of change of deviation of the plate thickness at the exit side of a rolling machine. CONSTITUTION:The deviation of plate thickness DELTAh of a rooled metal 1 at the exit side of the rolling machine 4 is tracked and measured by an exit side thickness measurer 6 and the measured value is stored in a controller 10. The acceleration or deceleration of speed of the rolling machine 4 is recognized and whether the deviation of thickness value DELTAh is larger than the reference- deciding value (E) or not is decided. If the value DELTAh is larger than the value (E), the way of control is devided. When the speed is accelerated, the controlling constant (C) is reduced with 0.1 when DELTAh is plus and the constant (C) is added with 0.1 when DELTAh is minus. When the speed is reduced, the constant (C) is added with 0.1 when h is plus and the constant (C) is reduced with 0.1 when DELTAh is minus. Thus, the deviation of plate thickness is controlled not so as to be fluctuated.
