Title: Controlling method for injecttion of active carbon in water purification plant
Inventor: SUZUKI NORIHISA
IPC: C02F1/28
Filed: 1980-10-08
Abstract: PURPOSE: To obtain disinfected water free from noxious trihalomethane, when raw water is disinfected with chlorine, by detecting a mass of humic cohtent in the raw water, injecting chlorine into the raw water, and then charging active carbon in response to the amount of the humic content when a fixed period has passed after injection of chlorine.  
     CONSTITUTION: The raw water from a water-collecting source such as a river is introduced into a sedimentation pool 1, where sand is settled and separated from the water. The water is then disinfected in a water-reserving well 2 by injection of chlorine from a chlorine injector 9. Thereafter, the water is introduced into a mixing pool 3, where powdery active carbon is added to the water with an active carbon injector 8 and a flocculant is added at the same time to form flocks of sorid matters in th raw water. The flocks are then precipitated in a sedimentation pool 4 and the water is carried into a filtration pool 5 and filtered. Thus, purified water is produced. In this process, a small amount of raw water in the sedimentation pool 1 is sampled, its COD value is detected with a COD meter, and the detected value is compared with an allowable value in a comparing circuit 10. The comparison value is inputted through a time-delayed circuit 11 into an injection-control circuit 12, and the injection amount of active carbon  from the active carbon injector 8 is controlled by its output. Consequently, clarified  water free from noxions trihalomethane generated by reaction of chlorine with  humic content in the raw water can be obtained.

IPC: G11B7/12
Filed: 1983-07-29
Abstract: PURPOSE:To prevent a skew detection error due to the contents of a record signal by reflecting the light given from a diffusing light source on the recording surface of a disk to form a real image of the light source on a 2-split detector and using the output of the detector to control an optical pickup so that it is vertical to the recording surface. CONSTITUTION:The light delivered from a lamp 10 is irradiated on the recording surface of a disk 1 through a quadrilateral diffusing plate 11, and the reflected light is condensed on a 2-split photodetector 15 via a condenser lens 16 of a photodetecting part 13. Thus a real image 18 of a diffusing light source 9 is formed. Both the direction and the degree of the skew of the disk 1 are detected based on the difference between the outputs of areas 15A and 15B of the photodetector 15. Then an optical pickup is controlled so that its optical axis is always vertical to the recording surface of the disk 1. This reproducer prevents a skew detection error due to the contents of a record signal.

Title: Radio equipment to be shared by transmission and reception
Inventor: MOCHIZUKI TAKUSHI
IPC: H04B1/40
Filed: 1992-05-06
Abstract: PURPOSE:To switch transmission and reception required for one-way communication control by a simple constitution in transmission/reception shared radio equipment. CONSTITUTION:A C-class amplifier 1 is provided with the final stage of a transmitting high output amplifier 1. Direct current(DC) power source voltage is always supplied from a bias circuit 10 to the amplifier 1 through a resistor 11. Since a current Ic starts to flow into the amplifier 1 when a transmitting RF signal is fed, a voltage drop Vd due to the resistor 11 is detected by a comparator 14. When a switching transistor(TR) 15 is turned off by the detection output, a power source for a receiving low noise amplifier 4 is turned off. Consequently the size and cost of the equipment is reduced without requiring a special complex circuit for detection of transmission RF signals as well as a connector for inputting a transmission/reception switching control signal.

Abstract: PURPOSE:To promote transfer to an arc discharge and improve the starting performance by winding three layers of electrode coil around an electrode shaft of a main electrode in a light emission tube such that the first layer is rough while the second and third layers have predetermined coil length. CONSTITUTION:In a metal halide light emission tube encapsulated with mercury, metal halide and starting rare gas, electrode oil 7 is wound in three layers around the electrode shaft 6 of a main electrode provided in said tube. The first layer coil 7a is rough winding, while the coil length L of the second layer coil 7b and the coil length 1 of the third layer coil 7c are arranged to satisfy the relation 0.3<=(l/6L)<= 0.8. With such structure the glow discharge will occur at the top G of the coil 2b and the heat at the top G is prevented from radiating to the electrode shaft 6 and the discharge space by the coils 2a, 2c. Since the temperature rise at the top G is quickened, the transfer to the arc discharge is quickened resulting in the improvement of the starting performance.
