Abstract: PROBLEM TO BE SOLVED: To form a capacitor used for an integrated circuit that can follow high frequencies by injecting an impurity ion of high density to a mono-crystal silicon board using a white ribbon oxide film as a buffer. SOLUTION: An n-type mono-crystal silicon board 11 is oxide processed on its whole surface with a mixture gas of oxygen and nitrogen, then a P-well 15 and a silicon nitriding film are formed, and by forming a photo-resist in element domain and removing, a p-type high density impurity layer 19 and a gate oxide film 20 are formed after formation of a field oxide film 17 and a white oxide film, then the impurity diffuses toward the board. Then, a polycrystal silicon film 21 is formed and the silicon film 21 except for a capacitor domain is patterned by etching. A gate electrode on an upper electrode is formed, and after a layer insulation film 23 is formed, a wiring 24 is formed by activating the impurity by heat processing and opening a contact hole.  Therefore, a reduced resistance is realized without damage to other parts, so a capacitor that can follow high frequencies is formed without giving influences to other elements.

Abstract: PURPOSE:To convert data of m-bit width into data of optional n-bit width (m>n) by utilzing a 1H line memory for a vertical filter and extracting the data with the equal number of fits to the input number of bits to a video memory from the line memory. CONSTITUTION:A 2nd line memory 13 generates data of a final stage (256th stage) in 4-bits from the MSB side and applies the data to a video RAM 2. Simultaneously the data of the final stage in 2-bits from the LSB side are sequentially stored to a 1st stage 6-bit D-FF through four terminals toward the MSB side. Then the memory 13 acts like a parallel shift register of 384 stages in 4-bit width substantially and all data by one line are able to be stored in a 4-bit RAM. Data from the RAM 2 to a 3rd line memory 14 and a D/A converter 15 are transferred by using a clock from a PLL circuit 16 locked to a synchronizing signal in a video signal of a master screen.

Filed: 1993-12-28
Abstract: PURPOSE:To provide a vacuum cleaner easy to operate with a function of letting the cylinder automatically revolve when required without manual operation, and further improve the safety by protecting fingers of a user from being carelessly caught in the machine. CONSTITUTION:When cleaning a wooden floor, the bottom tip of a roller 20 is positioned above the front and rear wheels 12, 11. The roller 20 does not touch the floor, and accordingly, it does not rotate even when an air inlet 7 is moved. In this state, there is no outputting from neither a sensor 24, AND circuit 26 nor a driving circuit 27, thus an electric motor 17 does not function. Accordingly, a revolving cylinder 13 does not rotate. On the other hand, in the case of cleaning a carpet, front and rear wheels 12, 11 sink in the surface of the carpet and a roller 20 touches the carpet. When the air inlet 7 is moved on the carpet, the roller 20 rotates due to the frictional resistance against the surface and eventually functions. As an AND circuit 26 receiving output from a sensor 24 beings outputting, and an electric motor 17 starts driving by the driving circuit 27. Accordingly, a revolving cylinder 13 starts its rotary movement and functions.

IPC: H02M7/48
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To start the switching operation of a switching element positively even if power is shut off and then is turned on immediately. SOLUTION: When power is turned on and a discharge lamp 4 is on, capacitors C1 and C3 are connected to the base circuits of transistors Tr1 and Tr2 in parallel and the base circuits are in a low-impedance state since the terminal voltage of a capacitor C7 is fully high, a transistor Tr3 is on and FET Trs 5 and 6 are on. At this time, when the power supply is turned off, the terminal voltage of the capacitor C7 drops, a zener diode ZD1 is turned off, the transistor Tr3 is turned off, at the same time the FETs Tr5 and 6 are turned off, the capacitors C1 and C3 are separated from the above base circuits, and the base circuits become high impedance simultaneously and immediately, As a result, even if power is turned on immediately, the transistors Tr1 and Tr2 perform smooth switching operation and continue operation.

Inventor: ONO YASUHIRO
IPC: H05K1/02
Filed: 1993-12-28
Abstract: PURPOSE:To provide a flexible printed circuit board in double-layer structure suited for a high-speed signal transmission. CONSTITUTION:In a flexible printed circuit board 1 in double-layer structure, ground wire patterns 32 and 32' on the upper and lower surfaces of an insulating material strip 2 and each through hole 5 connecting the ground wire patterns form a plurality of small loops.
