Title: Sewage treating device
Inventor: KATAOKA KATSUYUKI
IPC: C02F3/06
Filed: 1990-03-08
Abstract: PURPOSE:To produce treated water with high efficiency by forming a bed packed with a granular filter medium having a specified sp.gr. at the upper part in a tank, providing an air diffuser below or in the filter medium bed, using the lower part as a settling part and furnishing a raw water inlet part to the settling part and a treated water outlet part at the upper part of the tank. CONSTITUTION:The raw water contg. SS, soluble BOD, etc., such as sewage is introduced into the settling part 5 in the tank from the raw water inlet part 6 to settle and separate SS in the raw water. The raw water with the SS separated and removed in the settling part 5 is passed as an upward flow through the bed 2 packed with the granular filter medium having >=1.0 sp.gr. at the upper part of the tank, hence the fine SS which has not been settled and separated at the settling part 5 is filtered off, and the soluble SS is removed and the NH4 is converted to N by the action of the biological membrane deposited on the surface of the filter medium constituting the bed 2. The oxygen necessary for the absorbing action of the biological membrane deposited on the filter medium surface is supplied from the diffuser and allowed to ascend in the bed 2.

Title: Lighting system
Inventor: MURAKAMI KENTARO
IPC: F21V7/09
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a lighting system having excellent focusing performance such that no color aberrations and unevenness occur even with a light source of a wide wavelength range or of short wavelengths. SOLUTION: Light from a lamp 10 is focused by reflectors 40, 50 which extend along an ellipse (e) whose foci are located at the luminescent point P and focusing point Q of the lamp 10. The focusing point of a light beam reflected by the center reflector 40 and re-transmitted through a bulb 11 is made to deviate from the focusing point Q by the action of the bulb 11 as a negative lens, but the focusing point Q provided by the reflector 50 and that provided by the reflector 40 are made to almost coincide with each other by moving the reflector 40 a predetermined distance δ from the ellipse (e).  Further, the reflecting surface of the reflector 40 is made into an aspherical surface to correct spherical aberrations that occur when the light beam passes through the bulb 11, and an imaging magnification achieved by the reflector 50 at the focusing point Q and that achieved by the composite optical system of the reflector 40 and the bulb 11 are made to almost coincide with each other to prevent brightness unevenness.

     CONSTITUTION: The inside of an enclosed container 1 is provided with an ultrasonic wave absorption structure. A liquid 2 is filled in 70% of the capacity of the container 1. An ultrasonic wave converter 3 is attached to the central part of the bottom of the container. An ultrasonic lens 4 is located on the top of the converter 3 to face the surface of the liquid. The converter is connected to an ultrasonic processor 5. A rod 6 is secured with struts 7 on the bottom of the container 1. When the surface of the liquid 2 in the container is parallel with the bottom surface of the container, ultrasonic waves emitted from the converter 3 by the output of an ultrasonic oscilator 52 proceed toward the surface of the liquid 2 as shown by a full line in Fig. and are regularly reflected by the liquid surface. The reflected waves proceed in the direction of a dotted-line arrow and are received by the converter 3. The reception is indicated by a detector 53 and a display unit 54. A direction perpendicular to the ground surface can be detected from the indication. When the surface of the liquid 2 is oblique, the ultrasonic waves are absorbed by the inside surface of the container 1. At that time, indication is not performed.

Title: Signal line changeover circuit
Inventor: KAMEI SHINJI
IPC: H03K17/62
Filed: 1991-02-26
Abstract: PURPOSE:To prevent another signal line or another circuit from being affected by not applying a signal to a signal line not selected by a selector switch from the signal block to a switch block. CONSTITUTION:A selector switch 7 is thrown to the position of a contact R at the recording and an output of a gain variable amplifier 3 is led to a detection circuit 8. Since a switch 24 is opened and then a switch 25 is closed, a voltage Vcc of a power supply line 26 is applied to an emitter of an emitter follower 23 of block 12a through the switch 25 and a signal line 15. Thus, an emitter follower 23 is turned off and no signal is outputted from an amplifier 12 to the signal line 15. In this case, an emitter follower 22 is set on without being affected by the operation of the switch 25. Thus, since no signal is given to the signal line not selected by a selector switch 7 from the signal block, a non-riquwired signal line does not give any effect on another signal line and another circuit.
