Abstract: PURPOSE:To prevent operation stop or deterioration of the whole structure of a cell module in a power generating furnace by forming cell module from a plurality of unitary cell modules in series connections, and furnishing the terminals being led out of the furnace. CONSTITUTION:A plurality of unitary cell modules Al-An are connected in series in a power generating furnace 10 to constitute one cell module 12. From these cell modules, terminals B1-Bn+1 are led out of the furnace 10 through leads, and the amount of current flowing through each unitary module is made control table by connecting these terminals with one another or by connecting a bypass circuit between two terminals. If during long-term operation, deterioration or any failure is sensed in for example a cell module A2 in operation, a bypass circuit incl. external power supply is inserted between the plus side terminal B2 and minus side terminal B3. Propagation of the deterioration of cell module A2 can be stopped by bypassing the cell module A2 to sink the amount of the current flowing through it.

Title: Frequency conversion circuit
Inventor: NAGASE TORU
IPC: H03D7/18
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent the reflected wave of an image signal from entering the signal output terminal of a mixer and to stabilize the power level of the output signal of a frequency conversion circuit regardless of the frequency of an intermediate frequency signal by providing a resistance line having specific resistance value and a transmission line having specific length between the mixer and a BPF. SOLUTION: A resistor 7a having the resistance value equal to the characteristic impedance of a transmission line connected to a signal output terminal 5 of a mixer 1 and a transmission line 8 connected to the other end of the resistor 7a and having the length of 1/2 wavelength of an image signal are provided between the mixer 1 and a BPF 2. In such a constitution, the image signal is short-circuited by the input terminal of the BPF 2 which transmits a desired signal and attenuates the image signal. Therefore, the image signal is apparently terminated by the resistor 7a at a point ahead of the line 8. As a result, the reflected wave of the image signal is never inputted to the terminal 5 of the mixer 1.

Such strip is passed through a quick cooling zone 4 and a controlled cooling zone 5 and is annealed in an overaging zone 6, by which the tensile strength, yield point, elongation, Lankford value and crystal grain size of the steel strip as a blank plate for plating are adjusted. The steel plate is introduced, in succession thereto, into a vacuum sealing device 8 via a nitrogen replacing chamber 7 and seal rolls 7. Vapor 9 of molten Zn 11 is then plated by vapor deposition on one surface of the strip 18 in a vacuum deposition device 10. Zn is likewise plated by vapor deposition on the other surface in a vacuum deposition device 10'. The steel strip is passed through a vacuum sealing device 8' and a nitrogen replacing chamber 7' and is electroplated thereon with Zn in an electrogalvanizing cell 15. The above-mentioned method is also utilizable for an alloy in place of single metal such as Zn.

Title: Active fet body device and manufacture therefor
Inventor: ASSADERAGHI FARIBORZ
IPC: H01L23/52
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To obtain an active FET body device capable of balancing high-speed electric charges, decreasing off-current, and increasing on-current. SOLUTION: This embodiment comprises a silicon substrate 2, a silicon dioxide layer 3, a monocrystal silicon layer 4, a silicon dioxide layer 5, a spacer 13 of N+ doped polysilicon, a conformal layer 15 of a conductive diffusion preventing substance, a metal silicide layer 16, a CVD silicon dioxide layer 17, an insulator spacer 18, a silicon oxide layer 19, and a polysilicon 21. In an off-state, a gate contact with a body holds the body at a low word line level. In this state, a threshold takes a larger value. In addition to a voltage added to the N+ part 13 of a gate conductor, a potential from the body to a source rises. As a result, if the device is turned on, Vt lowers. By the effects of a dynamic Vt fall accompanied by a low off-current, this embodiment is suitable for a device using a very low voltage.

Title: Variable power supply
Inventor: HATSUTORI HIDEO
IPC: G05F1/573
Filed: 1983-11-29
Abstract: PURPOSE:To obtain the new set value quickly and with high accuracy when the set value is changed by controlling the electric power to be supplied to a heating wire so as to obtain a fixed sum total between the detecting resistance and the power consumption of each heating wire. CONSTITUTION:A heating wire 7 is unified thermally with a current detecting resistance 3, and the electric power P is supplied to the wire 7. Then the power P to be supplied to the wire 7 is controlled to obtain the fixed value for P+E<2>/R or P+RI<2>, where R, E and I show the resistance value, the set voltage and the set voltage and the set current respectively. As a result, the heating quantity of a composite material of the resistance 3 and the wire 7 is kept constant regardless of the set value. Therefore the temperature is also kept constant. Then it is possible to eliminate a problem where the temperature and the resistance value change since the heating quantity of the resistance 3 differs according to the set value to produce a drift to the set value.
