Title: Sonar
Inventor: SHIMIZU TOSHIO
IPC: G01S7/527
Filed: 1983-12-27
Abstract: PURPOSE:To extract even a feeble signal immediately after a high-level pulse by applying a mean signal to a mean circuit when a detected output signal exceeds the time mean signal thereof by a predetermined level. CONSTITUTION:A signal A detected and outputted with a detection circuit 1 is delayed by a time equivalent to the half of the time means of a means ciruit 3 with a delay circuit 2. The signal A is also intputted into one inlet of a selection circuit 10 while an output signal E of the mean circuit 3 for determine the time average of the output of the circuit 10 is fed back to the other inlet of the ciruit 10. The circuit 10 compares the signal A with the signal E to select the signal E when the signal A is inputted as exeeding the signal E by a predetermined level. Then, the signal E is inputted into an output circuit 11 together with the output signal C of the circuit 2 and a signal G with the controlled level is outputted.

Title: Image forming device
Inventor: KUSUMOTO KEIJI
IPC: G03G15/01
Filed: 1987-10-02
Abstract: PURPOSE:To improve the separation property of a paper in a photosensitive body separating part when humidity detected by a humidity detecting means deviates from a permissable level by automatically attaching toner whose color is the same as that of the paper onto a photosensitive body corresponding to an edge part on a paper feed side. CONSTITUTION:When there is a coincidence in color between the paper and the toner, which is identified by paper color identifying means 32 and 33 and toner color identifying means 4a-6a and only when the detected humidity of the humidity detecting means 36 is judged that it deviates from the permissable level, the developing devices 4-6 are selectively driven so that the toner whose color is the same as that of the paper is attached onto the photosensitive body 1 corresponding to the fixed area of the edge part on the paper feed side. The separation property from the photosensitive body of the edge part is improved. In addition to that, toner is attached by driving the developing device having the toner, whose color is selected for image forming, in areas other than the specified area. Thus, the separation property of the paper in the photosensitive body separating part is improved and the occurrence of paper jamming can be prevented.

Title: Waste water treatment
Inventor: TASHIRO EIICHI
IPC: C02F3/00
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of excess sludge and to increase a treating capacity by adding the prescribed quantity of succinate indicated by the specified formula to the total waste water. SOLUTION: Succinae indicated by the formula (R represents a hydrocarbon group) is diluted and is added to a process of biological treatment. A place to be added may be any point such as a sedimentation tank and an aeration tank. And the adding quantity is 10-1000 ppm, and since this amount depends on the amount (concentration) of organic matter in water water, it is not constant and is determined by comparing with MLVSS (organic matter content) of waste water to be treated. In the case of ordinary domestic waste water, 30-500 ppm is most effective. And since the treating method can be performed similarly to the conventional biological one, special contrivance or equipment is not needed at all.  In this way, since by a treating device of the same capacity, various treatment can be performed and the generation of excess sludge is notably reduced, labor cost and time required for removing it can be sharply reduced and a bed smell is not given off.

Title: Apparatus for deaeration by heating, method for deaeration by heating, and vacuum distillation apparatus and vacuum distillation method
Inventor: CHIBA AKIZO
IPC: F28B3/00
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To easily carry out deaeratian of a solution by providing a deaeration-by- heating mechanism to generate a vapor by heating a solution and deaerates dissolved air, a heat-exchange mechanism to condense the generated vapor by a heat-exchange apparatus, and a discharging mechanism only for the condensed water and evaporated air. SOLUTION: Air in an evaporator 11 is removed by replacing air with a vapor and, after that, the inside of the evaporator 11 is kept in air-free state by being shut from the outside. Then, sea water is led to a pipe 12 in the evaporator 11 to condense the vapor and decrease the pressure of the evaporator 11. The sea water which passes the evaporator 11 is indirectly heated by the vapor, further heated in 11 deaeration tank 13 until the sea water boils, and due to the boiling, dissolved air in the sea water is removed. The sea water from which dissolved air is removed is introduced into a vapor generating chamber 4 of the evaparator 11 through a pipe 15 and, since the inside of the evaporator 11 is at a lowered pressure, evaporation is accelerated.  The generated vapor is transported to a cooling and condensing chamber 16 and cooled to become fresh water and separated from concentrated sea water and discharged.

The 1st developing device 4 contains developer consisting of magnetic carries and insulating color toner, while the 2nd developing unit 5 contains developer consisting of magnetic carrier and normally used insulating black toner. By replacing the whole developing device with assembly, toner of any color can be selected.

Title: Temperature fixing method of laser beam machining system
Inventor: IWASAKI TAKASHI
IPC: B23K26/00
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption by changing the capacity of a cooling equipment according to the thermal load generated in the laser beam machining system. SOLUTION: Most of the thermal load generated in the laser beam machining system is generated from a laser beam oscillator 3. The heat radiation of the laser beam oscillator 3 is proportional to the discharge injection power. The laser beam oscillator 3 is operated by the command of an NC equipment 7, and the output command value from the NC equipment 7 is the discharge injection power to the laser beam oscillator 3. The output command signal of the NC equipment 7 is used as the signal of the thermal load of a cooling equipment 9, and when the cooling capacity is controlled in proportion to the signal, the cooling capacity in balance with the heat radiation of the laser beam oscillator 3 is obtained. A buffer tank of the cooling water can be reduced in size. The power consumption can be reduced. An existing program of the NC equipment 7 can be used.  Because the temperature of the cooling water is controlled in advance, the accuracy of the temperature control can be improved. The operation of the laser beam is stabilized.
