Title: Noise elimination circuit
Inventor: KOMURO SETSU
IPC: H04N5/21
Filed: 1988-02-20
Abstract: PURPOSE:To naturally eliminate a noise by controlling the mixing level of a noise according to the signal level of a video signal. CONSTITUTION:A difference between a video signal 1H delayed in a 1H delay line 3 and a video signal which is not delayed is taken in a differential amplifying circuit 4 to extract a noise component, limit in a limiter circuit 5 so as not to apply a large loss and input to the mixing control part 10 of a mixing circuit 6 in an opposite phase. The video signal is detected in a detecting circuit 11 to output the level signal of the video signal. When the level signal is high, the quantity of eliminating the noise component in the mixing control part 10 is reduced and when a S/N is small, the quantity of mixing in the mixing control part 10 is increased to completely eliminate the noise from the video signal.

Title: Method and instrument for measuring grain size of coke
Inventor: MATSUNAGA MASAO
IPC: C21B5/00
Filed: 1992-02-25
Abstract: PURPOSE:To obtain a means which can accurately and automatically obtain the information about the grain size of cokes from each coke oven by simultaneously performing sampling and grain size measurement upon applying a picture processing technique to the grain size measurement of the cokes. CONSTITUTION:While coke grains (c) from which fine particles are separated are dropped down in a hopper 1 provided with an image pickup camera 6, the pictures of the coke grains are taken and processed by regarding the grain sizes as the lengths of the shortest sides of the circumscribed rectangles of the pictures and volumes of the coke grains as equivalent spheres. Upon applying the picture processing technique, the disturbance is minimized so as to improve the measurement accuracy by establishing a picture taking environment in which overlapping of coke grains (c) is prevented by providing a screening plate, scattering coke grains, and reducing the transferring speed of a belt conveyor 2.

IPC: G06T11/00
Filed: 1993-02-26
Abstract: PURPOSE:To make even a small character font easy to see by generating dot data consisting of plural pixels, extracting the data by specific areas, and performing gradation processing. CONSTITUTION:A dot data means 12 generates dot data consisting of plural pixels showing a character font and an area extracting means 14 extracts the dot data by the specific areas. A multi-level font processing means 16 performs the gradation processing of the extracted dot data by the areas to generate multi-level font data. Here, the multi-level font data showing the character with density information on dots as the display font of the character are generated, so when there is a thick line drawing in an area, the multi-level font value becomes large and the font is displayed in, for example, black and when there is a thin line drawing in an area, the multi-level font value becomes small and the font is displayed in, for example, white. Consequently, when characters constitute a document of some size, characters of the multi-level font become easier to see.

Title: Cooling/heating apparatus
Inventor: WATANABE TAKAO
IPC: F24F11/76
Filed: 1983-03-11
Abstract: PURPOSE:To make it possible to perform smooth cooling or heating with the cooling capacity and hot air current temperature being prevented from lowering and also with a noise being prevented from being made, by using members of a configuration memory alloy in passages so as to control the flow rate of an air current so that the flow rate of an air current can be changed to follow the cooling operation or heating operation in a cooling/heating apparatus including a heat exchanger for heating with a burner and a heat exchanger for cooling. CONSTITUTION:When heating is carried out, the configuration memory alloys 13 receive heat from fins 8 by the heat generated by the burning operation of the heat exchanger 3 for heating and push air flow control plates 14 to close the passages between heat screening plates 12 and covers 10. Accordingly, after the current from a blower 4 comes in well contact with the heat exchanger 3 for heating and the fins 8 and exchanges the heats, the current is sent via the heat exchanger 2 for cooling into the room. When cooling is carried out, the configuration memory alloys 13 are not heated, and the passages of the heat screening plates 12 remain open, so that the current can pass through the passages between the fins 8 of the heat exchanger 3, the heat screening plates 12 and the covers 10. Thus, the flow rate of an air current can be changed to follow the heating operation or cooling operation, the cooling capacity and hot air current temperature can be prevented from lowering and a noise can be prevented from being made.

Inventor: ISHIZUYA TORU
IPC: G01J5/38
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To facilitate the assembly and to vary characteristic unique to the device. SOLUTION: The inclination of respective reflection parts 5 arrayed on a substrate 1 in two dimensions vary corresponding to the heat generated by a corresponding infrared-ray absorption part which absorbs infrared rays from a heat source 31. The readout light from a light source 10 becomes a nearly parallel light beam 52 through a lens system 11 to irradiate the respective reflection parts 5 obliquely. Its reflected light beam 53 passes through the lens system 11 and only a desired light beam of the light beam 54 having passed selectively passes through a light transmission part of a transmission type liquid crystal panel 12.  The passing light beam 55 reaches the photodetection surface of a CCD 20 arranged conjugately to a reflection part 5 through the lens system 12, so that an optical image composed of images of respective reflection parts 5 is formed on the photodetection surface. The reflective reflection parts 5 differ in the quantity of image light according to the inclination of the reflection parts. In this constitution, the positions, sizes, etc., of light transmission parts can be set by a setter 42.
