Title: Monitoring device of rotary shaft sensor
Inventor: KAJIMA TAKASHI
IPC: G01B7/30
Filed: 1982-12-03
Abstract: PURPOSE:To obtain a solid device, which can detect the abnormal operation of a machine beforehand, by checking the output of an angle sensor by a comparator circuit at a predetermined rotary position by using a pulse sensor. CONSTITUTION:An angle sensor 1 is coupled to a rotary shaft and connected to latch circuits 5 and 6 through a converter 8. The bit number of the angle signal, which is given to the latch circuits 5 and 6, is determined by the abnormal detection sensitivity of the angle sensor 1. In the case of 8 bits, 360/2<8>=1.4 deg. is obtained. When the angle sensor is different by + or -0.7 deg. or more from the correct value, the angle sensor 1 judges the abnormality. This is kept in the latch circuits 5 and 6 by the rise up of a pulse signal, which is applied to a terminal CK of the latch circuit 5. The outputs of the latch circuits 5 and 6 are sent as 8 bit signals from terminals Q. The output signal A from the terminal Q of the latch circuit 5 is imparted to a terminal A of an adder circuit 7. The output signal B from the terminal Q of the latch circuit 6 is imparted to a terminal B of the adder circuit 7. The signals A and B are added and outputted to a terminal S.

Title: Microwave discharge light source apparatus
Inventor: OONUKI KAZUSHI
IPC: H01J65/04
Filed: 1982-12-06
Abstract: PURPOSE:To obtain a necessary amount of light required for exposing within a constant period, irrespective of a change of rising characteristic of light flux by providing a means which detects and integrates the light from electrodeless discharge lamp and by controlling a switch connected to the charging capacitance by such integrated value. CONSTITUTION:The microwave generated by a magnetron 1 propagates within a waveguide and is radiated to the cavity 4, forming a microwave field within the cavity 4. The rare gas of discharge lamp 6 discharges by such microwave field and the light having the particular luminous spectrum depending on the kind of metal gas is emitted. However, the time for obtaining a constant amount of light t1 changes due to fluctuation in manufacturing of discharge lamp 6, ambient temperature environment and restarting condition. Accordingly, an optical output Aa from the electrodeless discharge lamp 6 is detected and such output and the other optical output B are integrated (with time) from the strating period. When an integral value of output A and BXT become equal (time T), the switch Ts is opened. Thereby, if the rising characteristic changes like A' in the figure, any effect is given to the required time t and it can be made constant for the required total amount of light indicated by the area OBoBt1.t1.

Inventor: YODA HIDEO
IPC: B30B11/00
Filed: 1986-09-10
Abstract: PURPOSE:To prevent an increase in the size and weight of equipment by connecting a mold plate to a crank mechanism, disposing lower pestles to a crank arm in such a manner that the pestle can move upward and downward in mold holes, disposing upper pestles to face the mold plate and permitting the positional adjustment thereof. CONSTITUTION:The mold plate 11 formed with the plural mold holes 10 is mounted to a fixing base 9 of a vertical interlocking plate 6. The plate 6 is fixed to a main spindle 5 pivotally fitted to the crank arm 4. The lower pestles 15 are fitted into the mold holes 10 and are so constituted that the pestles can move vertically. A feeder 22 is disposed above the mold plate 11. The powder in the feeder 22 is charged into the mold holes 10 when the feeder is slid and advanced. The plate 6 is moved upward by the arm 4 to fit the upper pestles 20 into the holes 10, thereby stamping the powder. Since the mold plate 11 is vertically moved together with the lower pestles 15, the stamping force increases. The increase in the size and weight of the equipment is thus prevented.

IPC: F23N1/00
Filed: 1989-08-22
Abstract: PURPOSE: To prevent production of nitrogen oxides by employing a catalyst containing palladium and enabling high catalyst activity and operating a catalytic combustor using a new combination of operating factors effective for sustaining and regenerating the high catalyst activity. CONSTITUTION: Fuel and air pass together through a mixer 17 and enter into a precombustion chamber 20 into which hot combustion gas is sprayed from a preburner 12. A catalyst is located on an integrated support 10 and hot combustion gas moves downward therefrom to drive a gas turbine 30. Hot gas flow from the burner 12 is utilized for heating up the catalyst to an initial temperature of 800 deg.C or above, e.g. decomposition temperature of the catalyst. Subsequently, hot gas flow from the burner 12 is reduced while supplying combustion air and fuel to the downstream of combustor in the preheater 20. Temperature of the catalyst is then lowered down to a regeneration temperature range and sustained thereat until a desired catalytic activity is achieved thus recovering catalytic activity and sustaining the temperature of the catalyst at about 800 deg.C or below.
