Title: Sewage treating device
Inventor: IZUMI SEIJI
IPC: C02F3/00
Filed: 1994-05-02
Abstract: PURPOSE:To eliminate the influence of a fluctuation in an inflow rate by executing a biological treatment under an aerobic condition in an aeration chamber, executing a sepn. of solid from liquid with a membrane separator which is immersed into an activated sludge mixing liquid and utilizes a natural water head as a driving pressure and automatically changing the filtration rate thereof by the fluctuation in the natural water head meeting the fluctuation in the inflow rate of the water to be treated. CONSTITUTION:The water which is to be treated and is introduced by a supplying pipe 2 for the water to be treated is subjected to removal of extraneous matter by a screen 7 of a filter section 8 and is sent to the aeration chamber 3. This water is mixed with the activated sludge mixing liquid in the aeration chamber 3 and aerating air is supplied to the water by a blower 18. The water is thus subjected to the biological treatment under the aerobic condition. On the other hand, the other end of a filtrate pipe 15 is installed in a position lower than the lower part of membrane cartridges 12 of the membrane separator 10. The activated sludge mixing liquid in the aeration chamber 3 is supplied to the upper part of the membrane cartridges 12 via the filtrate chamber 5, by which the natural water head is generated. The sepn. of the solid from the liquid is executed by the membrane cartridges 12 with this natural water head as the driving pressure.

IPC: F25B1/00
Filed: 1995-04-19
Abstract: PURPOSE: To prevent refrigerant from being decomposed under an abnormal high temperature of the refrigerant and to perform a forced convection cooling of a compressor by a method wherein when a temperature of discharged gas is detected and this detected gas temperature keeps an abnormal temperature of the discharged gas for a specified period of time, the compressor is stopped in its operation and a blower is electrically energized and driven subsequently even after the compressor is stopped in its operation. CONSTITUTION: If a temperature of a discharging pipe of a compressor is increased and a temperature detected by a discharged gas sensing means 6 keeps a higher temperature than an abnormal temperature of the discharged gas for a specified period of time, for example, 5 seconds, the operation is transferred to a discharged gas abnormal mode. Then, a compressor 1 is turned off by a relay 11 and is stopped in its operation for a predetermined period of time. However, a fan motor 4 is electrically energized and driven as it is after elapsing a specified period of time. Then, after elapsing a specified period of time, the relay 11 is turned on by a control circuit 13, the compressor 1 is again electrically energized and driven to start a cooling operation. At this time, the fan motor 4 is subsequently electrically energized and driven.  With such an arrangement as above, a recovering of the compressor 1 is rapidly carried out, an inner side of a refrigerator is cooled again to enable a foodstuff in the refrigerator to be prevented from being decayed.

Title: Detection of class of recording sheet
Inventor: SUZUKI AKIO
IPC: B41J29/38
Filed: 1988-04-18
Abstract: PURPOSE:To remove a malfunction of a recording process by automatically detecting a class of a recording sheet and to achieve extension of an adoption width of the recording sheet, by a method wherein a quantity of reflected light from a front surface and a rear surface of the recording sheet is detected, and its class is discriminated based on a difference in reflected light between the front and the rear surfaces or on a quantity of the reflected light of either side surface. CONSTITUTION:Sensors 66, 67 detecting conditions of a front surface and a rear surface of a recording sheet are arranged at required positions on a path of a recording sheet 45, and detection signals 66A, 67A from the sensors are transmitted to a control circuit 53. In the case of a coarse surface of paper or the like, light of an intensive directivity irradiated through a slit 73 from a light source 71 is scattered on a surface of the recording sheet 45, and a quantity of reflected light incident upon a light receiving element 72 arranged on a path of the reflected light decreases to a low level of a fraction of irradiation light. In the case of a smooth surface such as a surface of a BPF or the like, the quantity of reflected light incident upon the light receiving element 72 does not decrease less than irradiation light, and is kept at a high level. Thus, a class of, or a front or rear surface of the recording sheet 45 can be detected based on a difference in the quantity of reflected light between the front and the rear surfaces of the recording sheet, or otherwise based on the quantity of reflected light of either side surface.
