Title: Decoder ic card and scramble system
Inventor: OI SHINICHI
IPC: H04N21/4623
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a scramble broadcast decoder IC card and a scramble system where the number of trial audio visual IC cards is never limited by the number of receiver ID (identification code) bits. SOLUTION: A decoder IC card 11 can be attached to and detached from the device body of a scramble broadcast decoder and controls the scramble. In such card 11, a decoding key (Km) and a tentative receiver identification cord (tentative ID) are previously stored in the nonvolatile storages 31 and 33 for the audio and visual purposes. In a formal reception contract mode, a normal receiver identification code(normal ID) that is multiplexed to an enciphered broadcast is fetched by means of the tentative ID and then decoded by the Km. The decided normal ID is stored in the storage 33.

IPC: H04Q9/00
Filed: 1994-02-02
Abstract: PURPOSE:To control a motor driving voltage without requiring any special electronic parts or mounting space by changing the duty ratio of an output signal from a remote control output terminal. CONSTITUTION:The REM terminal of a microcomputer 1 is connected through a transistor 3 and an integration circuit (a resistor 7 and a capacitor 8) to the VS terminals of motor driving circuits 9 and 10, the transistor 3 is turned on/off by outputting a '1' /'0' signal in a fixed cycle from the REM terminal, and the motor driving voltage is controlled by changing the duty ratio of this signal. When the duty ratio of the output signal is changed by the microcomputer 1, the valid driving voltage is changed and therefore, the turning speed of motors 11-14 is changed. Thus, the motor power supply voltage can be extremely easily and economically controlled without requiring any special electornic parts or space like the conventional method, and power consumption can be reduced as well.

Title: Color copying device
Inventor: KURAMOTO AKIMASA
IPC: H04N1/48
Filed: 1986-01-23
Abstract: PURPOSE:To obtain a sharp black picture without mixed color with less power consumption by using two image sensors, projecting an infrared light to one sensor among reflected lights from an original so as to obtain a signal for a black picture only, projecting a visual light to the other sensor so as to obtain a signal and synthesizing the said signal after being inverted. CONSTITUTION:An original 1 is scanned by a halogen lamp 2 and a mirror 3. The mirror 4 is a dichroic mirror reflecting an infrared ray and transmitting a visual light and the reflected infrared ray is formed to the sensor 6. Although the sensor 6 cannot identify the white background and a color character among the black and color characters on the original printed on the white background since the print ink absorbs the infrared ray, only the back character remains in the picture of the sensor 6 by the reflected infrared ray. The visual light transmitted through the mirror 4 is formed on the sensor 7 as the cyanide and black picture by the lens 5 and the red filter 8. The output signal of the sensor 6 is inverted by an inverting circuit 10 and synthesized onto the output signal of the sensor 7 and only the cyanide signal is inputted to an optical printer 9. Similarly, the black character picture not being a mixed color is obtained by using a green/blue filter 8.

Title: Molten metal level position measuring method for dual-drum type continuous casting
Inventor: UEJIMA YOSHIYUKI
IPC: B22D11/16
Filed: 1995-01-27
Abstract: PURPOSE: To accurately detect the position of a molten metal level even when the surface of a drum reflects a light emitted from the high-temperature molten metal by using a polarizing lens in the case of measuring the molten metal level position in a dual-drum type continuous casting, and forming the image of an image receiver by the transmitted light of the lens. CONSTITUTION: A molten metal level position is measured based on the image of a boundary 8 between the molten metal 1, the image of which is received by a CCD type image receiver 10 and the surfaces of the drums 2, 2' of a dual-drum type continuous casting machine. In the case of measuring the level position, a polarizing lens is used to form the image of the receiver 10 by the transmitted light of the lens. When the radioactive ray of the sum generated from the surfaces of the drums 2, 2' is passed through the lens, the ray from the metal 1 reflected on the surfaces of the drums is cut off by the lens. Accordingly, the image of the receiver 10 becomes a tint image corresponding to σT1 <4> (where T1 is the absolute temperature of the molten metal) of the metal 1, the images of the drums 2, 2' become dark color images corresponding to σT24 (where T2 is the absolute temperature of the drum), and hence the boundary is clarified.

Title: Canned motor pump
Inventor: HASHIMOTO KAZUAKI
IPC: F04D13/06
Filed: 1983-01-29
Abstract: PURPOSE:To hold the amount of lubricating liquid to a minimum required limit so as to reduce a leakage amount in a pump part and improve efficiency of a pump, by setting the flow path resistance for the lubricated surface of a front bearing larger than the flow path resistance for the lubricated surface of a rear bearing. CONSTITUTION:For a front bearing 30, a large differential pressure is generated between a front rotor chamber 34 and a shaft through hole 52 of a partition 46 communicated to the low pressure part of a pump chamber 18, but in this case, the internal peripheral surface, being a lubricated surface of the front bearing, is not provided with a groove and setting flow path resistance to a large level, accordingly the internal peripheral surface can hold the amount of lubricating liquid to the front bearing in a minimum required limit. On the contrary, the internal peripheral surface being a lubricated surface of a rear bearing 32 is provided with a helical groove 62 engraved in the direction allowing the liquid to easily flow when a rotor shaft 24 is turned or a straight line 64 engraved in the axial direction thus setting flow path resistance to a small level, accordingly the internal peripheral surface can hold the amount of lubricating liquid in a minimum required limit similarly to the above described. Accordingly, a leakage amount in a pump part is reduced, and improvement of the total efficiency of a pump can be easily attained.
