Title: Operation control device for marine engine
Inventor: IWATA YOSHIFUMI
IPC: F02D41/16
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent an engine stall, by controlling ignition timing according to an extremely-low-speed rotational frequency at a more delayed angle than that at idling rotation, when the engine rotational frequency decreases to the extremely-low-speed rotational frequency lower than the idling frequency in the condition that a throttle valve a aperture is substantially the full opening. SOLUTION: In the case of switching an operation lever to the back running position during running ahead, when the engine rotational frequency decreases to the extremely-low-speed rotational frequency lower than the idling frequency by rotation of the operation lever to a neutral position, ignition timing is controlled to correspond to the engine rotational frequency and elapsed time detected at that time. In other words, as soon as the engine rotational frequency decreases to the extremely-low-speed rotational frequency, ignition timing is controlled to an ignition timing T2, and then gradually to the neighborhood above the dead point (TDC) with a delay angle. Furthermore, when the engine rotational frequency rises with the passing of time, the ignition timing is progressed near an ignition timing T1. Thus, necessary rotation power can be secured, and engine stall can be avoided.

Title: White balance adjustable tv camera system
Inventor: HIDARI HIROBUMI
IPC: H04N9/73
Filed: 1992-05-20
Abstract: PURPOSE:To allow an object to be shown as a white object to surely show white by indicating an optional position on an output picture, extracting the video signal of the indicated position and adjusting white balance based upon the video signal. CONSTITUTION:A controller 25 in a frame memory device 20 stops the input of an image signal inputted from a TV camera 10 to a memory element 22 to stop image output from the element 22. When a user points out a position to be processed by white balance on the screen of a monitor 30 by means of a user's light pen 26, a pointing mechanism 24 inputs a position signal to a controller 25. The controller 25 obtains a video signal corresponding to the position pointed out by the light pen 26 and transfers the video signal to a controller 13 in a TV camera 10. The controller 13 computes gain for allowing the specified position to show white. The computed gain is applied to respective output signals outputted from an image pickup element 11 by a white balance adjusting circuit 12 and the signal adjusted at its white balance is outputted to the device 20.

IPC: G11B5/39
Filed: 1988-05-24
Abstract: PURPOSE:To enable the reproduction with good sensitivity from a medium formed with narrower tracks by disposing a nonmagnetic conductor bridged and installed with a magneto-resistance effect element between either of the middle of 3 leader terminals and either of both ends to the spacing between two shielding magnetic materials. CONSTITUTION:The magneto-resistance effect element 35 having the 3 leader terminals 32-34 is sandwiched between a magnetic substrate 11 and the shielding magnetic material layer 18 by nonmagnetic insulating layers 12, 17 to constitute the head. The element 3 bridges the middle among the common leading out parts consisting of the nonmagnetic conductor films of the three terminals and either of both ends. Taking out of the intermediate terminal 33 is, therefore, easy even if the core width W for formation of the magnetic recording medium to the narrower tracks is decreased; in addition, the thermal noises by heat generation of the element 35 are effectively removed at the time of reproduction by setting this terminal at a reference potential and differentially detecting the potentials outputted to the terminals 32, 34 of both ends. The reproduction characteristic of the good sensitivity is thus obtd.

Title: Bias current control circuit
Inventor: HATAKEYAMA MOTONOBU
IPC: B41J2/30
Filed: 1995-05-26
Abstract: PURPOSE: To prevent futile power consumption by connecting a switch to a base of a transistor(TR) so as to execute on/off-control of the TR, thereby controlling a current supplied to a bias circuit. CONSTITUTION: A photo interrupter circuit 2 is provided on the way of a carrying path so as to allow paper to pass between a diode 10 and a transistor(TR) 11. When the paper is carried and passes between the diode 10 and the TR 11, a light of the diode 10 is interrupted by the paper and no light is given to a base of the TR 11. Since no current flows through a resistor R5, an output voltage END-P of the resistor 5 changes. Thus, whether or not the paper is normally carried is detected and discriminated by a voltage change. Since the bias current control circuit 3 supplies a current to the bias circuit only when a voltage change is detected, the TR 12 is turned on/off. Thus, only when the bias circuit requires a power supply, the current is supplied, then the power consumption is reduced.
