Title: Floating point addition/subtraction device
Inventor: MIYOSHI AKIRA
IPC: G06F7/50
Filed: 1990-11-28
Abstract: PURPOSE:To simplify a circuit and to shorten the time required for operation by providing a circuit which does not shift an operand mantissa part whose index value is smaller for aligning digits in two operands before it is shifted to right, or which shifts and digit to right or left. CONSTITUTION:The shift means 103 which does not shift the mantissa operand before the addition/subtraction of two mantissa part operands is executed based on information whether two pieces of data to be operated are normalization numbers or non-normalization numbers or whether an execution operation is addition or subtraction, or which shifts it to right or left by one digit is pro vided. Consequently, only one subtraction circuit 104 calculating the shift quan tity of an operand mantissa part is required. Thus, a floating point addition/ subtraction device where the circuit is simple, power consumption is small and the time required for the operation is shortened can be obtained.

Title: Node assembly of magnetron
Inventor: SAI HEITAI
IPC: H01J25/587
Filed: 1992-12-14
Abstract: PURPOSE: To prevent abnormal oscillation and reduce parts cost by performing a plating processing with oxygen free copper in which impurity material content is extremely reduced on the surfaces of a hollow anode cylinder and a flat plate anode vane which are formed by electrolytic copper. CONSTITUTION: An anode cylinder 2a and an anode vane 10a are formed by electrolytic copper and a plating of oxygen free copper of prescribed thickness is performed for the external surface of an anode assembly. When magnetron constituted in this way is operated, generation of gas due to impurity materials at working space 12 between a filament and the anode cylinder 2a is prevented because of layers of oxygen free copper 20 formed on the surfaces of the anode cylinder 2a and the vane 10a when microwave energy is generated by thermoelectron discharged from the filament. As a result, the pattern of a frequency mode within working space is maintained constant and exact oscillation can be obtained.

Title: Liquid crystal element and production of liquid crystal element
Inventor: TOKUNAGA HIROYUKI
IPC: G02F1/136
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To produce MIM(metal insulator metal) elements of a small capacitance by an inexpensive and simple process. SOLUTION: The MIM elements 11 are formed on a lower substrate 10 by successively laminating metallic layers 12, insulating layers 13 and conductive layers 14. The surfaces of the metallic layers 12 among these layers are provided with ruggedness of a prescribed roughness and the insulating layers 13 are formed thin only in the projecting parts. Then, the metallic layers 12 and the conductive layers 14 eventually conduct to each other only near the projecting parts of the metallic layers 12 and the capacitance of the MIM elements 11 may be made smaller than the capacitance of liquid crystals 15. Consequently, sufficient voltage is eventually impressed on the MIM elements 11 and the liquid crystals 15 are switched. There is no need for forming slopes on the metallic layers 12, unlike heretofore. The production stages are made simpler and the production cost lower.

Abstract: PURPOSE:To utilize effectively the capacity of a DC power,source device for backup of small size and low cost CONSTITUTION:When power is fed from a commercial AC power source, the voltages of condensers C6, C7 become equal mutually so as to produce no voltage at the output terminal of a rectifying bridge composed of diodes D6-D9. Accordingly a photo coupler PC is set to an off state so that no signal is input to an inverter control circuit 5, and a lamp 6 is lighted with normal output by an inverter circuit 3. If a DC power source E is applied at interruption, the voltage of either of the condensers C6, C7 becomes higher, and current flows to the light emission diode side of the photo coupler PC. The current is input to the inverter control circuit 5 as an lights-out signal. If a switch SW is set to an off state, the lamp 6 can be lighted even at the interruption.
