Title: Twist drill
Inventor: HATTORI TATSUO
IPC: B23B51/02
Filed: 1989-03-09
Abstract: PURPOSE:To drill a hole without causing burrs or peeling due to reinforcing fibers by forming a twisted groove into a helical shape advancing in the direction of rotation according as it goes from the tip side toward the base end side, and making web thickness of a drill body 8-20% of the diameter of the drill. CONSTITUTION:A twisted groove 2 is formed into a helical shape advancing in the direction of rotation according as it goes from the tip side toward the base end side, and web thickness of a drill body 1 is kept at 8-20% of the diameter of the drill. Aa a result, axial rake angle of a cutting edge 3 becomes minus, and reinforcing fibers can be cut as if they were cut off with scissors. No reinforcing fibers thus remain on the surface machined by the cutting edge 3, and frictional resistance between the drill body 1 and a hole is small since the web thickness of the drill body 1 is thin. Reinforcing fibers can thus be cut with good cutting action, and thereby generation of burrs or peeling on the edge part and the inner periphery of the hole can be efficiently prevented.

Title: Method for displaying abnormality discriminating area for image processor type state monitoring device
Inventor: KAWAMOTO OSAMU
IPC: G01M3/00
Filed: 1991-03-20
Abstract: PURPOSE:To easily input an appropriate abnormality discriminating value in accordance with a monitored image so as to improve the operability of the title device by displaying the abnormality discriminating value on the same screen together with the monitored image as an area. CONSTITUTION:When an abnormality discriminating value is inputted from a processing condition input section 6 in the unit of cm<2>, the value is sent to a picture processor 4 by means of a signal 12. A telephoto degree signal 9 obtained from a TV camera 1 with zoom lens and distance signal 10 obtained from a distance sensor 7 are transmitted to the processor 4 through a TV camera control section 2 and the extent of the visual field of a monitored picture is calculated from the telephoto degree and distance. Then the abnormality discriminating area (cm<2>) is displayed on a screen by finding the area value of one picture element by converting the extent of the visual field into the number of picture elements and calculating the number of picture elements of the abnormality discriminating area (cm<2>). Therefore, the abnormality discriminating area can be compared with the picture at a glance and an abnormality discriminating area suitable for the screen can be easily inputted.

Abstract: PURPOSE:To reduce an input side harmonic wave current, to improve an input power factor by a main converter, to reduce a size and a weight and to enhance an efficiency by adding a capacitor, an inductor and a diode to the converter. CONSTITUTION:Energy charged in a capacitor 4 flows through a conversion transformer 5, a switch element 6 and a diode 13 in a state that the element 6 is closed, and is discharged to a secondary side through the transformer 5. Simultaneously, a current IBR flows through the capacitor 4, an inductor 12 and a diode 15 to charge the capacitor 4. Then, if the element 6 is turned OFF, energy stored in the inductor 12 flows through the inductor 12, a diode 14 and the capacitor 4 to charge the capacitor 4. Thus, harmonic wave components of an input current of a converter are removed, and an input power factor is improved.

Title: Voltage current conversion circuit
IPC: H03F3/34
Filed: 1992-03-16
Abstract: PURPOSE:To allow the circuit to be operated by an input voltage Vin from being almost at a ground potential and to surely output a current in response to the input voltage with less V/I conversion error. CONSTITUTION:A collector of a transistor (TR) Q1 receiving an input voltage Vin is connected to a R Q3 being a component of a current mirror circuit CM2 via TRs, Q5, Q2 and a resistor R1 being components of an impedance conversion circuit CM1. A current flowing to the TR Q5 is proportional to a current flowing to the TR Q2 by the current mirror CM3. Since the current flowing to the TRs Q1, Q5, Q2, Q3 is equal to each other, the base-emitter voltage of the TRs Q1, Q5, Q2, Q3 is cancelled and the conversion error is reduced.
