Title: Methane fermentation method
Inventor: KAMEOKA TOSHINORI
IPC: C02F11/04
Filed: 1987-01-28
Abstract: PURPOSE:To generate a high-calorie gas with high efficiency by deproteinizing blood stock, etc., methane-fermenting the stock, circulating the generated gas to agitate the methane-fermentation soln., and removing ammonia and hydrogen sulfide in the course of circulation. CONSTITUTION:Acetic acid, etc., are added to the blood stock or meat stock generated from the aquatic food processing to coagulate and separate protein. When the deproteinized soln. is methane-fermented in a methane fermenter 1, the methane fermentation soln. 5 is agitated by circulating the generated gas. Ammonia is removed by the sulfuric acid 3 in a sulfuric acid tank 22 in the course of circulation, and hydrogen sulfide is removed by the iron oxide 4 in an iron oxide-packed vessel 23. As a result, the blood stock or meat stock which has been difficult to normally methane-ferment heretofore can be used as the raw material in this method, a high-calorie gas can be stably generated with high efficiency from the material, and the separated and recovered protein can be used as a high-quality feed stuff.

Title: Image exposing device
Inventor: TAKEUCHI YUKIHISA
IPC: H04N1/107
Filed: 1989-01-31
Abstract: PURPOSE:To prevent picture quality from being deteriorated due to oscillation at the part even when interruption/re-start is performed during a reading operation by providing a buffer memory to store image data exceeding one scan data of an optical scanning means at an image processing part, and also providing a control means to control the driving force of a driving means. CONSTITUTION:The image processing part is provided with the buffer memory 25 to store the image data exceeding one scan data of the optical scanning means, and also, is provided with the control means 27 to control the driving force of the driving means 9. The unrequired torque of a motor 9 can be reduced by reducing a motor driving current at a time when the rotation of the motor 9 arrives at a constant rotating state after the reading operation is re- started, which suppresses oscillation in the motor itself or a scanning system. Also, since the scanning system performs no waste reciprocal movement after the interruption of the reading operation, it is not feared that additial time for reading time is attached. In such a way, smooth picture quality equivalent to that in continuous reading can be obtained even an interruption/re-start operation is performed during performing the reading of an image, and also, reading speed can be preveted from being lowered.

Abstract: PURPOSE:To prevent a time lag due to calculating time of a disturbance estimating observer from occurring in a speed control system by performing speed detection at first upon provision of the edge of an FG and then outputting a result thereafter performing calculation in the disturbance estimating observer. CONSTITUTION:The controller comprises an FG section 2 for converting the angular speed of a motor 1 into Frequency Generator(FG) frequency, a speed detector 3 for detecting a speed based on the FG frequency, and means for operating a disturbance estimating observer 12. Upon input of the edge of the FG, speed is detected at first and the speed detection result is added to a calculation result of the disturbance estimating observer 12 at the time when the edge of preceding FG is inputted, and then a calculation is carried out in the disturbance estimating observer 12 and the calculation result is added to the speed detection result. Consequently, speed detection is carried out immediately upon input of the edge of FG and the detection result is outputted. By such arrangement, time lag due to calculation time of the disturbance estimating observer 12 is prevented from occurring in the speed control system.

Abstract: PURPOSE:To make it possible to coexist improvement of power in high speed with improvement of combustibility in low speed and light load by setting the opening timing of an intake valve positioned for from an exhaust valve earlier than the opening timing of an intake valve positioned at the exhaust valve side. CONSTITUTION:The opening timing of an intake valve 3 is set earlier than exhaust/intake valves 1, 2. The overlapped term of the intake valve 3 and exhaust valves 11, 12 is thereby lengthened. Consequently, scavenging in a com bustion chamber 7 can be accelerated in high speed to improve charging effi ciency for aiming at improvement of power of an engine. Meantime, the over lapped term of intake valves 1, 2 and the exhaust valves 11, 12 are set relatively short so that the spitting of burned gas toward intake ports 4, is not increased particularly. Even if the overlapped term of the intake valve 3 and the exhaust valves 11, 12 is long, the intake valve 3 is arranged relatively for from the exhaust valves 11, 12 so that the spitting of burned gas toward the intake port 6 is not increased particularly.

Abstract: PURPOSE:To make the title driver less susceptible to the effects of external noises and variations in voltage, without modifying the hardware of the driver, by providing a process of writing data from a driving signal generating part into a signal holding part, in a process loop which is provided in a control program for the driving signal generating part and is repeated at predetermined time intervals. CONSTITUTION:Driving data to be outputted is prepared in an MPU in a step P6, and then the content of a timer function incorporated in the MPU is cleared in a step P7. In a step P8, the driving data is written from the MPU into a flip-flop, and a driver causes an actuator to start operating according to a driving signal from the MPU. Next, in a step P9, the timer in the MPU is started. When it is detected in a step P10 that the content in the timer reaches a set value, the step P7 is again executed to clear the timer, and the same data as the previous data is written in the step P8. Therefore, the rewriting of the data does not cause any change in the operation of the actuator. The above operations are repeated until the driving data is changed to the next driving data.
