Title: Flowing water energy recovery method and apparatus
Inventor: KAWASAKI HIDEAKI
IPC: F03B13/08
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To recover the energy of flowing water at high recovery efficiency by rotating a water turbine by flowing water, and rotating an air compressor by the water turbine to manufacture compressed air. SOLUTION: A water stream of a dam final effluent or the like is let flow in a water turbine 1 from a water inlet 5 through a flow regulating valve 11 to rotate the water turbine, and then released from a water outlet 6. The rotation of the water turbine 1 is accelerated through a step-up gear 2, and an air compressor 3 is driven at the accelerated rotating speed. Thus, the air sucked from an air suction opening 7 of the air compressor 3 is compressed, and the compressed air is sent from a discharge opening 8 to a tank inlet 9 to be stored in a storing tank 4. The compressed air in the storing tank 4 is taken out through a discharge valve 12 to be used.  Thus, the rotating force of the water turbine 1 is transmitted to the air compressor 3 through the step-up gear 2 to be driven, so that even if the rotating speed of the water turbine 1 is changed, the air compressor 3 can be operated without any obstacle.

Abstract: PURPOSE:To obtain a proper control of a throttle valve opening degree even in case of a false contact of an idling switch by providing a control means to drive an actuator in accordance with the difference between an actual opening degree and a target opening degree of the actuator. CONSTITUTION:In case of a false contact (NG) of an idling switch ISW and a dash pot mode is released, the dash pot is not controlled. The termination of the dash pot is decided when a target planned opening degree PSI becomes equal to a water temperature opening degree PTW. A motor 5 is controlled to rotate for pulling an actuator rod 7 backward with a pulse width of L1 till a switch 10 is put on and as soon as the switch is put on, the rod 7 is pushed forward with a pulse width L2 and stopped at the right position when the switch is put off. Then, the rod 7 is projected up to the target opening degree PS, i.e. the water temperature opening degree PTW to keep an opening degree of a throttle valve 2 properly. Also when an air-conditioner is switched from ON to OFF, just like the above case, a calibration is made to eliminate a speeding at the time of a high speed revolution.

Title: Camera provided with automatic focus detector
Inventor: HONMA AKIRA
IPC: G02B7/34
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To align the position and the range of a range-finding zone on a photographic image plane or a finder visual field with the position and the range of actual range-finding regardless of subject distance and focal distance by selecting a line sensor used for detection based on the variance of an optical device. SOLUTION: In the case of wide-angle photographing, range-finding is executed by utilizing a substance image projected in a light receiving range 53W, that is, range-finding calculation is executed by using signal charges accumulated in all the photodetectors of the line sensor 52A. In the case of standard photographing, range-finding calculation is executed by using the photodetector in a narrower light receiving range 53S and in the case of telephotographing, it is executed by using the photodetector in a much narrower light receiving range 53T. Thus, the width of the line sensor 52 is made larger than the conventional one, and the light receiving range of the line sensor 52 used for the range- finding is selected in accordance with the field magnification of a variable power finder. Therefore, the size of the range-finding zone in a finder visual field 56 becomes constant regardless of the field magnification and coincident with that of a range-finding frame.

Filed: 1981-07-21
Abstract: PURPOSE:To prevent a film end from being detected erroneously, and to reduce power consumption, by providing a latency time switching means, and varying the latency time length of said means. CONSTITUTION:When there is a great difference in the time from the starting of film feeding to the ending of winding owing to a difference in the kind of a film, for example, when the drawing-out torque of a film is large, the time from the starting of film feeding to the generation of a winding completion signal is set long with a changeover switch 6 to lower the possibility that a part other than a film end is recognized as the film end erroneously. When the drawing-out torque of a film is small, the latency time is set short to reduce the power consumption even if the film is tensed at its film end.

Abstract: PURPOSE:To perform control of an advance angle to an optimum value responding to the state of an internal combustion engine by a method wherein by using the maximum delay angle correction item of a plurality of delay angle correction items containing a delay angle correction item for at least acceleration, an advance angle item is corrected to determine a final ignition advance angle. CONSTITUTION:In a control device 1, by effecting interpolating computation of the map of a memory 45 by means of a processing circuit 43, in relation to an advance angle item, a fundamental advance angle item ABSE is determined based on the rotation speed of an internal combustion engine and the state of a load and an advance angle correction item ACLD based on a cooling water temperature. In relation to a delay angle correction item, a delay angle correction item ATRN and a delay angle correction item ATRQ responding to the speed change motion of a transmission are respectively determined from the change rate per a unit time of an intake air pressure by a circuit 43. A delay angle correction item is selected from a total sum of all delay angle correction items during steady running in which the correction item ATRN is below a given value and a highest delay angle correction item is selected during acceleration in which it exceeds the given value. This method determines an ignition timing by means of a final ignition advance angle the advance angle item of which is corrected.
