Title: Treating apparatus of waste water through use of rudaceous material having capillary void
Inventor: NIIMI TADASHI
IPC: C02F3/00
Filed: 1978-07-19
Abstract: PURPOSE: To accelerate propagation of microbes even in the cobble layers on waste water surface and obviate clogging by letting waste water or the like ascend in the capillary voids possessed by the cobble-form material filled in a vessel and letting microbes live.  
     CONSTITUTION: The cobble-form material 3 having capillary voids such as lapilli peaks at its central part and protrudes above the side wall 2 of the water vesssel composed of the bottom wall 1 and side wall 2. A netting 4 is put on the top of the cobble-form material 3 and is covered thereon with soil. Since this is so designed that waste water ascends like the arrow A along the capillary voids of the cobble- form material 3 and that when the capillary water becomes insufficient the waste water is supplied at all times from below, the conditions under which microbes are liable to live are established. The anaerobes live in the capillary voids in the cobble-form material 3. In the soil on the cobble-form material 3, purification by plant roots, soil small animals, etc. takes place.

Title: Engine controller
Inventor: SHIBANO MASARU
IPC: G05B9/02
Filed: 1994-04-26
Abstract: PURPOSE:To prevent an engine from being broken by preventing the contents of a ROM from easily be modified on the market. CONSTITUTION:A program in the ROM 8 is provided with a deciding function which decides whether or not the ROM data are regular data and if it is decided that control data are modified, control output from a CPU 3 is stopped. Consequently, a CPU backup circuit 12 judges abnormality of the CPU 3 and switches the mode to a CPU backup mode to perform control under which only an irreducible necessary run is allowed. Therefore, if the ROM data are altered on a user side, engine output is never increased more than necessary and the engine is prevented from being broken owing to alterations of the engine controller 1.

Title: Device for preventing radiator from clogging
Inventor: MUTO TOSHIMI
IPC: F01P11/06
Filed: 1994-04-26
Abstract: PURPOSE:To prevent impurities from reversing by pouring the impurities in engine cooling water from a cooling water path to a reserve tank in one direction. CONSTITUTION:A radiator constituting a portion of a cooling water path of an engine cooling water circulating system performs the breathing action between the radiator and a reserve tank. In the expansion of cooling water accompanying heating, impurities in cooling water flowing in a cooling water circulation system flow from the cooling water path to the reserve tank in one direction to accumulate in a receptacle of the reserve tank. The impurities in the cooling water are accumulated in the reserve tank by repeating the running and stop of the engine. In the reserve tank, an immersion pipe 17 immersed in the cooling water, a ball 27 for opening and closing an exhaust port 25 according to the flow of the cooling water and a mesh filter 20 provided on the radiator side rather than the valve position are provided. The path resistance of the mesh filter 20 is larger than that of the exhaust port 25.

Title: Toner remainder detector of electrophotographic copier
Inventor: MARUYAMA KOUJI
IPC: G03G15/08
Filed: 1978-07-21
Abstract: PURPOSE:To exactly detect the amount of toner remainder, by electrically catching decrease of torque in the drive motor of a developing unit. CONSTITUTION:Drop of development torque can be caught as drop of the current of a drive motor circuit. The current value of drive motor 7 of a developing vessel can be caught by resistance 9 as voltage change. This voltage is rectified and amplified and sent to comparator 12, where a reference voltage is set to the voltage level corresponding to current Ci at the limit point of developing ability due to consumption of the toner, and the above detected value is compared with this set value. When the detected value exceeds the set value, comparator 12 provides a signal to indicate this state in display device 13, permitting the toner remainder limit to be exactly detected.

IPC: G01P5/00
Filed: 1993-04-15
Abstract: PURPOSE:To highly accurately detect the velocity and the direction of the flow of a fluid in a gas flow velocity detecting apparatus, to detect an abnormal value of the apparatus itself thereby to find the calibrating/repairing timing and to improve the temperature characteristic. CONSTITUTION:Three flow sensor elements 1M, 1Y2, 1Y3 having different maximum detecting/sensing directions are used. The first flow sensor element 1M is used to detect the speed of a main flow, and the second and third flow sensor elements 1Y2, 1Y3 are used to detect a side flow. The angle of a gas and the size of the flow velocity are obtained from a state functional formula of the detected value of the main flow by the first flow sensor element and that of the side flow by the second and third flow sensor elements. When the difference of corrected outputs of the second flow sensor element 1Y2 and the third flow sensor element 1Y3 is larger than a preset value, an abnormality signal is generated. Further, the detected value by each flow sensor element is corrected by the output of a temperature sensor for the temperature correction.

Title: Casting method in twin roll type continuous casting machine
Inventor: FUKASE HISAHIKO
IPC: B22D11/06
Filed: 1983-05-20
Abstract: PURPOSE:To permit easy startup of continuous casting for a thick steel strip by starting casting at a small roll gap in the stage of starting charging of a molten metal with a twin roll type continuous casting machine then increasing gradually the roll gap. CONSTITUTION:A twin roll type continuous casting machine is so constituted as to draw a metallic strip from a roll gap by rotating plural horizontally and parallelly disposed rolls and supplying a molten metal thereon. The roll gap is decreased in the state of starting charging of the molten metal and casting is started from the metallic strip thinner than the prescribed thickness at a relatively high circumferential speed of the rolls to prevent generation of splashes and V-blocks. The roll gap is then increased and at the same time the circumferential speed of the rolls is made lower than the speed for casting the thinner strip, by which the thick metallic strip is cast. The generation of splashes right after the start of charging the molten metal is avoided by the above-mentioned method without using a dummy bar to permit easy startup and casting efficiency is improved.
