IPC: B63H20/08
Filed: 1984-03-19
Abstract: PURPOSE:To exclude the troublesomeness in manual lock operation by permitting the locking into the tilt state automatically when an outboard motor is put into tilt-up state. CONSTITUTION:When an operating lever 28 for releasing tilt lock is turned clockwise, a reverse lock hook 25 turns upwardly through a link 30, and the engagement with a thrust rod 24 is released.

Title: Automatic transmission for four-wheel drive vehicle
Inventor: HOJO YASUO
IPC: B60W10/10
Filed: 1990-03-05
Abstract: PURPOSE:To provide a sufficient start accelerating property even if the distribution ratio of a driving force is changed by constituting a value of change gear ratio at the lowermost speed stage in nearly even distribution ratio larger than that in the uneven distribution ratio. CONSTITUTION:An electronic control unit E calculates speed change stages to be set on the basis of the input data of vehicle speed, throttle opening, shift position signal, cooling water temperature, distribution ratio of a drive force in a transfer 7 and the like so as to output signals to a hydraulic controller C. The electronic control unit E enlarges in response to the distribution ratio in the transfer 7 the change gear ratio of the lowermost speed stage in nearly even distribution ratio and lessens the change gear ratio of the lowermost speed stage in the more uneven distribution ratio. Thus, even if torque appearing on output shafts 5, 10 as the change gear ratio is enlarged, the torque is distributed relatively uniformly to four wheels according to the distribution ratio to provide a start accelerating property near limit torque shared by tires.

Title: Camera
Inventor: KANEKO KIYOTAKA
IPC: H04N5/238
Filed: 1988-03-07
Abstract: PURPOSE:To obtain a correct exposure level and a satisfactory color reproduc tion by executing a shutter speed prior exposure in a exposure time integer-fold that of the period of the luminance ripple of an illuminating light source, and adjusting a white balance to the color temperature of the illuminating light source. CONSTITUTION:Whether the light source to illuminate a subject has the luminance ripple or not is detected by a sensor 42, and when it has the luminance ripple, the period is decided. A CPU 26 executes the shutter speed prior exposure in the period integer-fold that of such a period. Further, a light from the light source is light-received for the period integer-fold that of 1 period, the color temperature is detected by a signal arithmetic circuit 43, and the white balance is adjusted to the color temperature. Thus, even under the light source to have the luminance ripple such as a fluorescent lamp, the correct exposure can be always executed even through the use of an image pick-up element, in which a dynamic range is narrow, such as an electronic still camera, and an image with the satisfactory color reproduction can be obtained.

Title: Recording and reproducing device for magnetic card of lamination of temperature sensing magnetic material
Inventor: ASHIKAWA MASATAKA
IPC: G11B5/02
Filed: 1979-05-02
Abstract: PURPOSE:To provide a magnetic card with the function of protection by using the magnetic card formed of temperature-sensing materials stacked on a magnetic film with the function of magnetic recording and reproduction. CONSTITUTION:In the section of a magnetic card, a magnetic film of high coercive force are applied on substrate 1 in stripes and on magnetic film 2, temperature- sensing magnetic material 3 with a Curie point much lower than that of the magnetic film is stacked. Recording head core 4, even in contact with temperature-sensing magnetic material 3, is unable to perform recording below the Curie point of magnetic material 3 even when a current is applied to recording coil 6. Additionally, even the movement of reproducing head core 5 in contact with magnetic material 3 never brings reproduction to effect because of a magnetic flux path formed of a magnetic flux form magnetic film 2 as shown by the dotted line. Heating temperature-sensing magnetic material 3 by a heating roller makes magnetic material 3 into a paramagnetic material exerting no influence on magnetic film 2, making it possible to pick up reproduced signals.

The invasion detecting means specifies the invading position of the object into the detecting area 10 based on the position of the light receiver which does not receive the beams. Thus the inexpensive invasion sensor having the flat invasion detecting area in a simple configuration can be obtained.
