Title: Distortion measuring method for lens for infrared camera
Inventor: MATOBA YUJI
IPC: G01M11/00
Filed: 1988-06-09
Abstract: PURPOSE:To accurately measure the distortion of a lens by an easy method by regarding spheres which have low emissivity as gauge marks, and irradiating infrared light with the wavelength range of the camera and taking a picture. CONSTITUTION:On a substrate 2 which is painted in black to have high emissivity, steel balls 5 which have the low emissivity and about 3mm diameters are fitted as the gauge marks longitudinally and laterally at constant intervals according to specific coordinates. Then, the light having the wavelength range that the infrared camera 1 has sensitivity to is irradiated from a heater 4 installed by the substrate 2 and the camera 1 which is installed in front of the substrate 2 takes a picture, so that a clear coordinate image of the part of the steel balls 5 is taken. Here, if the lens has distortion, the square coordinate images has distortion, so it is compared with specific square coordinates to find the distortion curve of the lens, which is used to correct the coordinates of the photographed image.

Title: Dry control system for grain dryer
Inventor: NISHINO EIJI
IPC: F26B25/22
Filed: 1990-05-30
Abstract: PURPOSE:To improve the dry efficiency of grains by controlling the process time which specifies the circulation and suspension of grains based on the time elapsed from the start of dry operation and the moisture of the grains and drying the grains accordingly when drying the grains through the ventilation of dehumidified air, circulating the grains intermittently. CONSTITUTION:While the grains are intermittently circulated from a storage chamber 1 to a dry chamber 2 by the intermittent rotation of a delivery valve 3, dehumidified air at a specified temperature and a specified humidity set from a dehumidification device is generated. When the dehumidified air passes through the dry chamber 2, the grains flowing in the dry chamber 2 are exposed to the dehumidified air so that the grains may be dried up. During the dehumidification/dry operation, when specified time passes from the start of dehumidification/dry operation or the moisture of the grains drops to a specified moisture and below, the process time which circulates and halts the grains is controllably reduced so that the grains may be dried up. This construction makes it possible to enhance the dry efficiency of the grains since surface dry is carried out while intermittent dry operation is properly used.

Title: Spot killer circuit and television receiver provided with the circuit
Inventor: KIKUCHI HIROAKI
IPC: H04N3/20
Filed: 1995-06-09
Abstract: PURPOSE: To completely eliminate a remaining raster and spot by grounding the second grid of a CRT for the prescribed time at the time of the initial motion of the rise and fall of a power supply voltage. CONSTITUTION: When a power supply switch is turned on, the voltage of a terminal T8 rises with a certain inclination. At the time, an instantaneous current is made to flow through a capacitor C3, a resistor R10 and the resistor R9 and a voltage drop is generated at both ends of the resistor R9. It takes the prescribed time for the voltage drop to turn on a transistor Q2. During the prescribed time, the voltage of the output terminal 7 of a focus block 2 is grounded through the transistor Q2 and thus, the voltage of the terminal 6, that is the voltage of the second grid, is kept at a ground voltage as it is during the time. Thus, in the period, the electronic beam of the CRT does not reach the tube surface and the remaining raster or spot is not generated.

Title: Logical gate circuit
Inventor: FUKUDA TERUMASA
IPC: H03K19/088
Filed: 1981-09-11
Abstract: PURPOSE:To quicken the operating speed without increasing power consumption, by providing a means for discharging a base storage charge of an output transistor (TR). CONSTITUTION:When a high level is applied to an input terminal 11, a current flowing to a resistor 1 flows to a base of a phase inverting TR22, a collector potential is decreased and a discharge TR29 is transferred from the interrupting state to the conductive state. In this case, the collector potential of the TR22 is lowered to cut off a level shift TR23. A stored charge of the base of a phase division TR24 is rapidly discharged to a discharge TR29 through a resistor 7 and that of an output TR27 is also to the TR29. Thus, the TR27 is transited to the cutoff state in high speed.
