Title: Picture special effecting device
Inventor: IIDA HIROYUKI
IPC: G06T3/00
Filed: 1985-10-07
Abstract: PURPOSE:To obtain the video special effect with high picture quality by dividing an input picture into the unit of triangle plates and applying coordinate conversion at every triangle plate. CONSTITUTION:A digitized input picture is divided into triangle plates by a conversion address operating circuit 13 and the divisions are adhered to an optional stereoscopic object, e.g., a sphere. A coordinate is subjected to coordinate transformation such as rotation or movement and the picture is converted on a new screen after the perspective transformation. A cave filling circuit 15 obtains all new pattern picture element addresses in the inside of the triangle plates from three apexes of the transformed triangle plate. An interpolation circuit 6 operates the addresses of an input picture corresponding one by one to the obtained new screen picture element addresses. The reduction rate of a picture applied to an LPF 8 inserted to prevent a reflection distortion is operated individually as the horizontal direction reduction ratio and the vertical direction reduction ratio by a reduction rate operation circuit 11 for each triangle plate subjected to coordinate transformation. Thus, the video special effect with high picture quality is attained.

Title: Range finder mechanism by image processing
Inventor: YANO HIROSHI
IPC: G05D1/12
Filed: 1991-09-03
Abstract: PURPOSE:To unnecessitate plural image sensors by obtaining two image data based on the positional change with time of the image sensors and measuring the distance to a target based on the viewfield angles of the image data and the moved distance between them. CONSTITUTION:An image sensor 2 attached to a mobile object acquires the image data on a target 1 by the infrared rays (passive). An image processor 3 analyzes the viewfield angle for the full length of the target 1 based on the image data given from the sensor 2. The viewfield angles lambda1 and lambda2 are respectively measured at time points t1 and t2 and outputted to a computer 5. Meanwhile an inertia navigation device 4 measures respectively the positional coordinates (x1, y1) and (x2, y2) at the points t1 and t2. Then the computer 5 calculates the moved distance between both coordinates and then calculates the distance between the mobile object and the target 1 based on the angles lambda1 and lambda2 and the moved distance between them.

Title: Optical heterodyne receiver
Inventor: WATANABE SHIGEKI
IPC: H04B10/516
Filed: 1989-08-31
Abstract: PURPOSE:To reduce the influence of phase noises of a transmission light source and a local oscillation light source by providing a narrow-band-pass filter circuit, a delay circuit, and a demodulating circuit which multiples and demodulates the output signals of both the circuits and sufficiently reduce the delay time difference tau of the two divided signals. CONSTITUTION:The optical heterodyne receiver which is applied to an ASK system branches an intermediate frequency signal from an amplifier 18 into two and inputs one to the narrow-band-pass filter circuit 20 and the other to the delay circuit 19. The signal delay time of the delay circuit 19 is set nearly equal to the signal delay time of the narrow-band-pass filter 20. In concrete, only the use of, for example, a conductor cable with proper length is allowed. The delay time difference tau needs to be reduce to 0 so as to make the influence of the phase noises as small as possible. Strict time matching like this, however, is performed by using a variable length coaxial tube or observing the delay of a pulse on an oscilloscope.

Title: Controller of separate type air conditioner
Inventor: MORI MASATO
IPC: F24F11/02
Filed: 1985-10-07
Abstract: PURPOSE:To carry out the defrosting operation only when frost is surely attached without lowering the cooling ability so as not to impair the comfortableness by rotating a fan motor in correspondence to the air flow direction at the outer part of an outdoor machine. CONSTITUTION:When it is assumed that a fan motor 11 is overloaded by an adverse air flow, a fan is rotated by the adverse air flow, and a voltage which is different from that at the ordinary time is produced between terminals of the fan motor 11. Upon this occasion, while the output of a comparator 19 is inverted depending upon the direction (polarity) of a terminal voltage, even when the terminal voltage is directed to any direction, it is smoothened by a diode bridge 23 and becomes a voltage at both ends of a resistor 27. When the voltage valve exceeds a threshold value (reference voltage) set by resistors 24 and 25, the output of the comparator 26 is inverted. Accordingly, after stopping the fan motor 11, when a microcomputer 13 detects that the output of a comparator 19 shows that the fan is rotating in a direction inverse to that before the stoppage and further the output of the comparator 26 shows that it exceeds the threshold value, the microcomputer 13 judges that the load is an overload due to the adverse airflow state, and an instruction for rotating the fan motor in a direction reverse to that before the stoppage of the motor is imparted to rotate the fan motor 11 in the reverse direction.

Abstract: PROBLEM TO BE SOLVED: To obtain a sufficient heat transmission restraining effect without degrading a signal transmitting characteristic of a low frequency area by forming external conductors as a double structure, and exposing only one end side of the inside external conductor outside. SOLUTION: First and second external conductors 10 and 11 are arranged in a concentric shape through a first dielectric 12.

Abstract: PURPOSE:To prevent any damage to the folded portion of a sack-like separator by making the separator by performing embossing work on a laminate body consisting of a microporous sheet containing polyolefin-system synthetic pulp and a nonwoven sythetic-fiber cloth so as to provide the separator with irregular wavy form. CONSTITUTION:After a microporous sheet 2 containing 15-65wt% of polyolefin- sysem pulp is heated with a preheating roller 3, a nonwoven fabric 5 made of polyproyleye fiber and supplied from a roller 4 is superposed on the microporous sheet 2. Next, the thus formed laminate body is heated and pressed with an embossing roller 6 to stick the microporous sheet 2 and the nonwoven fabric 5 together and to form an irregular wavy body 7, thereby making a separator. After that, a battery is constituted by folding the separator into sack-like form before a negative plate 8 is wrapped in the sack-like separator, being followed by placing the thus formed body in such a manner as to face a positive plate 9. As a result, any separation of an active material can be prevented by increasing the mechanical strength of the folded portion without increasing the thickness of the microporous sheet 2, and favorable electric resistance and acid-proof property can be realized.

Title: Thermal transfer recording medium
Inventor: KITAMURA SHIGEHIRO
IPC: B41M5/40
Filed: 1985-10-07
Abstract: PURPOSE:To provide a thermal transfer recording medium capable of applying good quality printing to rough paper inferior in surface smoothness, by setting the film thickness of an ink layer containing an aqueous emulsion of a thermoplastic resin to a specific value or less. CONSTITUTION:In a thermal transfer recording mediumm wherein a layer containing an aqueous emulsion of a heat-meltable substance is provided on a support and at least one ink layer containing an aqueous emulsion of a thermo plastic resin is provided thereon, the film thickness of the ink layer is set to 2mum or less. In such a case that the ink layer is formed of the aqueous emulsion, the adhesive strength between the ink layer and paper is slightly lowered as compared with such a case that the ink layer is formed of a solvent system but, because flocculation force is also lowered, this ink layer is extremely advan tageous in a thermal transfer system. If ink formed of the solvent based on a polymer is used, a whisker like stringing phenomenon is easy to generate at the edge part of a printed character but this phenomenon is less significant in the emulsion system. The thickness of the lower layer may be thin but, when thicker than the ink layer, especially good quality printing is obtained.
