Title: Constant current device
Inventor: MATSUDA TETSUYA
IPC: G05F1/00
Filed: 1988-05-10
Abstract: PURPOSE:To easily obtain a constant current device by providing a first superconducting material having a critcal current larger than a current supplied from the constant voltage power source and a second superconducting material having the critical current smaller than the current. CONSTITUTION:The title device has a first high temperature suprconducting material 1 having a critical current ICI larger than a current I of a lead wire 6 a little and a second high temperature superconducting material 2 having a critical current I$dc2$X smaller than the current I of the lead wire 6 a little. When the current I is larger than the critical current I$dc1$X of the first superconducting material 1, the first superconducting material 1 shows a normal conduction change, the whole resistance of the lead wire 6 including superconducting materials 1 and 2 rises and the current I is reduced. On the other hand, when the current I is reduced more than the critical current I$dc2$X of the second superconducting material 2,the second superconducting material 2 in the normal conduction condition is changed to the superconducting condition, the whole resistance of the lead wire 6 including the first and second superconducting materials 1 and 2 is reduced and a current is increased. Thus, a constant current action can be obtained.

Title: Range finder
Inventor: NONAKA OSAMU
IPC: G01C3/06
Filed: 1992-05-01
Abstract: PURPOSE:To enable a range finder to have multiple functions with simple circuit configuration without using any expensive IC for auto-focusing by controlling two current signals outputted from position detecting means by means of a switching means and amplifying all or part of the signals, and then, comparing the number of integrating times until the integrated value of the amplified outputs reach a prescribed value. CONSTITUTION:While two current signals corresponding to the incident position of light are outputted from two output terminals of a PSD 1, all of the current signals are inputted to an amplifying means 3 and integrated 8 when a change- over switch 10 is turned off. When the switch 10 is turned on, on the other hand, only one of the two signals is inputted to the means 3. When the numbers of integrating times until the integrated outputs reach prescribed values in the two state where the switch 10 is turned on and where the switch 10 is turned off are compared wit each other, the incident position of reflected signal light on the PSD 1 can be found without relying on the intensity of reflected signals from the object 11. Therefore, the distance to the object 11 can be accurately measured.

Title: Image processing method
Inventor: HYODO MANABU
IPC: H04N9/11
Filed: 1994-05-26
Abstract: PURPOSE:To correct the dispersion in a color temperature by recording color temperature information at image pickup to a magnetic recording layer formed to each frame of a photo film and applying image processing to the information when the film is reproduced based on the color temperature information. CONSTITUTION:An integration block 24 counts frequency for each gradation (e.g. 255) of a signal of a prescribed picture element number for each of R, G, B digital signals by one frame to generate a simple histogram. A CPU 28 uses the signal with low gradation whose accumulation frequency exceeds a prescribed value (e.g. 1% of total number) for a reference minimum value and uses the signal with high gradation for a reference maximum value. A signal processing circuit 22 conducts black level correction, white level correction and gamma correction or the like under the control of the CPU 28 and corrects the reference maximum value and the reference minimum value of the signals R, G, B to closer values respectively, then the signal is reproduced on a TV monitor with a matched gray balance. When color temperature information read by a magnetic head 14 is within a range of a day light color temperature, the said processing is implemented and when a color temperature at image pickup is other than the day light, since optical quality is corrected depending on the color temperature at image pickup, even when the color temperature at image pickup in dispersion, a frame image with excellent color reproduction is reproduced.

Title: Method for approximation to circle and arc
Inventor: ONDA TOSHIKAZU
IPC: G06T11/20
Filed: 1994-05-27
Abstract: PURPOSE:To speed up processing calculation when a dot array in image data is approximated to a circle or arc, to make the circle or arc pass a start point and an end point without fail, and to eliminate the need for a special CPU for the calculation. CONSTITUTION:In the step S1, the circle or arc which passes three points in total, i.e., two end points of the object dot array and another point is assumed when the dot array in the image data is approximated to the circle or arc. In the step S2, it is decided whether or not the point of the dot array other than the former two points is on the circumference of the circle when the circle or arc is assumed in the step S1, and when the decision result is YES, it is decided in the step S3 that all the elements in the dot array are on the circumference, so that the dot array is recognized as the assumed arc. When the result is NO, on the other hand, an advance to the step S4 is made to decide that there is a point farther away from the circumference than a certain distance, so that the dot array is not approximated to the arc. The step S1 is a process for selecting representative points of the dot array and when those dot array is the arc, the two end points are the start point and end point of the arc.
