Patent JP-S5897904-A (JP)
Title: High frequency generating circuit
Inventor: MORI MASAKAZU
IPC: H03B19/16
Filed: 1981-12-08
Abstract: PURPOSE:To generate higher harmonics by connecting a diode between the base of a transistor (TR) and an AC input terminal and further connecting another diode in the opposite polarity relation between the emitter and the AC input terminal, and thus folding an AC waveform. CONSTITUTION:The base B of an NPNTR4 and an AC input terminal 3 are connected mutually through a capacitor C3, a diode (D)1 and a resistance R6. Between the emitter E of the TR4 and the input terminal 3, a D2 connected reversely to the D1 and a variable resistance Rv are connected. When an alternating current appearing at the terminal 3 is positive, the TR4 operates as a common emitter TR and a negative component waveform appears at an output terminal 5 through the collector C. When it is negative, the TR4 operates as a common base TR and an univerted waveform is outputted to the collector C. Therefore, the AC waveform is folded and outputted from the output terminal 5. The waveform at this time takes a waveform obtained by rectifying the input alternating current on full-wave basis to generate higher harmonics easily.

Title: Device for working material wood into columnar body
Inventor: YABUSAKI OSAMU
IPC: B27L1/08
Filed: 1991-07-10
Abstract: PURPOSE:To work material wood into a columnar body having the smooth surface at a stroke by rotating an annular body and sending the whole cutter in the axial direction. CONSTITUTION:The title working device is constituted of both a roughing cutter A for roughly cutting a fixed material wood into a columnar body and a finishing cutter for finish-cutting this columnar body. A first roughing edge 4 is inserted freely movably forward and backward into a supporting hole 10 formed in a nearly truncated conical part 2. A supporting member 11 is fixed to the rear end of the supporting hole 10. Push bolts 12, 12 are screwed into the supporting member 11. The front ends of the bolts 12, 12 are allowed to abut against the rear end of the first roughing edge 4. Moreover a drag bolt 13 equipped with a stopper 13' in the rear end is inserted into the supporting member 11. The front end of the drag bolt 13 is screwed to the female screw of the first roughing edge 4. Thereby material wood is worked into a columnar body having required diameter at a stroke while both the roughing cutter and the finishing cutter are moved to the other end of the material wood from one end thereof. Therefore efficiency of working operation is remarkably enhanced.

Title: Semiconductor memory device
Inventor: TAKADA SHIGEKAZU
IPC: H03K19/0175
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To further decrease power source noises by further relaxing current consumption from a power source. SOLUTION: When the level of an input signal IN11 is 'H', an output control circuit 11 supplies electric charges stored in a first capacitor 25 to an output terminal 19 before applying the power supply voltage of a first power source. When the level of an input signal IN12 is 'H', the electric charges of the output terminal 19 are pulled to a second capacitor 26 before applying the power supply voltage of a second power source to the output terminal 19. Thus, since the level of the output terminal 19 is made close to the power supply voltages of the first and second power sources, a current to be consumed from the power source in the case of applying the prescribed power supply voltage to the output terminal 19 by turning on first and second transistors 18 and 20 is reduced. Therefore, power source noises can be reduced.
