Abstract: PURPOSE:To expand a detecting region readily and to improve resolution in the direction of a height by providing a filter to the rear stage of a conversion means, shaping the intensity of the detected signal, and making the resolution uniform. CONSTITUTION:An electron beam is condensed with an electronic lens. X-ray are projected on a substance to be inspected from an X-ray source 1. The transmitted X-rays are converted into visible light in a conversion means 3. When the visible light is transmitted or cut off, the amount of the image focusing light of the substance to be inspected 2 in the rectangular cross-section shape which is converged by an image focusing means 5 is corrected in the filter 4. The resolution of the visible light is made uniform in the filter 4.

Air arrives at the exhaust passage, which has become negative pressure, from an open air, which is in atmospheric pressure, through the dewing prevention suction hole 11 and mixed with combustion exhaust gas. In consequence of the above, the dew point in the inside of an exhaust extension pipe 4 is raised along with a rise in excess air factor of the combustion exhaust gas and it becomes that dewing in the inside of the pipe is prevented. In all sorts, therefore, of operation modes of a gas hot water supply device body 1, the dewing in the inside of the exhaust extension pipe 4 is prevented.

Title: System and device for file transfer
Inventor: NAKAMURA YOSHIHIRO
IPC: H04L23/00
Filed: 1990-03-19
Abstract: PURPOSE:To decrease the length of a data to be sent and received by coding the pattern of a character string and transferring the result by a file transfer device when it is discriminated that the pattern of the character string is identical to that already sent by a character string retrieval means. CONSTITUTION:When a command of file transfer is issued, a read control section 12 reads one by one character string sequentially from a file device 11. A deciding circuit 13 decides whether a read-out character string has a pattern having already sent or a first pattern. Thus, a retrieval control section 17 retrieves whether or not a character string of the same pattern as that of the read-out character string exists in a storage table 18. The circuit 13 decides the character string as an unsent pattern character string when the pattern is not retrieved and registers the pattern in a table 18 together with a code number and sends it to a transmission circuit 16. On the other hand, when the relevant character string is retrieved, the circuit 13 decides the pattern as the pattern character string sent already and sends only the code number added to the retrieved character string via the circuit 16. Thus, the length of data to be sent/received is reduced.

CONSTITUTION:A coder 1 separates an input video signal into a luminance signal and a chrominance signal at a Y/C separation circuit 11, they are ADD- converted by A/D converters 12, 13 and the result is stored in a frame memory 14. A frame format signal in the memory 14 is converted into a block format signal by a conversion circuit 17 and fed to an encoder 18. The encoder 18 encodes the signal by using a first weighting coefficient of a weighting matrix as complete M-bit data and by using a succeeding weighting coefficient being a difference from one-preceding weighting coefficient as N-bit data (N<=M).

Inventor: UEKI ISAMU
IPC: H03F3/343
Filed: 1980-05-26
Abstract: PURPOSE:To ensure a linear conversion between the voltage and the current, by inserting a current Miller circuit into a feedback circuit of a differential input operational amplifier and then flowing the current having no relation with the voltage between the base and the emitter of a transistor to an input resistance. CONSTITUTION:A negative input terminal of a differential input operational amplifier (amplifier) 6 is connected to an input terminal IN and a current Miller 7 via a resistance 5 of resistance value R, and the earth potential is connected to a positive input terminal. The output terminal of the amplifier 6 is connected to the other end of the Miller 7 to form a feedback circuit of the amplifier 6. With application of the positive signal voltage V to the terminal IN, a feedback is applied to set the voltage between two input terminals at 0. Thus the output of the amplifier 6 becomes negative to the earth potential by the voltage VBE between the base and the emitter of a transistor (TR) 8. Accordingly the current of flowing to the resistance 5 becomes V/R, and the samd current V/R flows to the TRs 8 and 9. As a result, an accurate voltage-current conversion is possible to flow the current proportional to the input voltage V to an output terminal OUT.

Title: Hot water tank with electric heater
Inventor: SUZUKI KOUICHI
IPC: F24H1/20
Filed: 1983-04-20
Abstract: PURPOSE:To prevent the wall of a resin tank from being heated to its melting temperature by a method wherein a plate-like heat dissipating member made of a metal is provided near both terminals of an electric heater held within the resin tank. CONSTITUTION:When an electric heater 2 is energized while the resin tank is not filled with water sufficiently by mistake, a thermostat heat sensitive section 4 is heated and the supply of electricity to the heater 2 is cut through a switching section 42. The heat at the center of the heater 2 is transmitted to both terminals of the heater. The heat thus transmitted is transferred to the heat dissipating plate and the heat is discharged into the air by radiation, condution or convection. Consequently, both terminals of the heater 2 are kept at a comparatively low temperature and the upper wall of the resin tank 1 is not deformed due to its melting by the heat.
