Title: Drill
Inventor: MURATA KOJI
IPC: B23B51/00
Filed: 1992-01-09
Abstract: PURPOSE:To completely cut glass fibers by forming the top end angle formed by a preceding edge to 20 deg.-40 deg.. CONSTITUTION:Cutting is first started with a preceding edge 5. Since the top end angle beta is formed to 20 deg.-40 deg., and the cutting force acting on the preceding edge 5 is large, glass fibers are completely cut even in the shaft center position of a drill body 1. Cutting with the outer circumferential end 4a of an outer circumferential edge 4 is then started. Since the angle alpha formed by an outer circumferential edge 4 and the direction orthogonal to an axial line C is 10 deg.-20 deg., the cutting force acting on the outer circumferential edge 4 is large, and therefore, the glass fibers are completely cut even on the outer circumferential end 4a of the outer circumferential edge 4. Further, by forming the axial step in difference between the top end 5a of the preceding edge 5 and the outer circumferential end 4a of the outer circumferential edge 4 to 25%-30% of the diameter of the drill body 1, the inside end 4b of the outer circumferential edge 4 can be situated sufficiently on the outer circumferential side from the shaft center position of the drill body 1, and the pressing force of this part can be reduced.

IPC: H05G1/32
Filed: 1982-01-13
Abstract: PURPOSE:To reduce to the utmost the difference between output voltage in time  of no-load and that in time of load in a high-tension transformer, by making up this power unit to control the bias voltage of a high-tension switching element  so as to cause the impressed voltage of an X-ray tube to be turned into the  specified tube voltage. CONSTITUTION:When a switching circuit 2 is turned on, a three-phase AC power supply 3phiAC is fed to a high-tension transformer 3 via both a tube voltage adjusting transformer 1 and the switching circuit 2 and, after the pressure is raised up, full-wave rectification is carried out with a high-tension rectifier 4 whereby the rectified power is fed to a high-tension condenser 5. Accordingly, the high- tension condenser 5 starts charging but the charge voltage is divided in part, which is detected by charge-voltage detecting resistors R2 and R3 and inputted into a comparator 11 in consequence. On the other hand, as this comparator 11 is provided with the output of an adding signal made by an adder 10 summing each signal corresponding to those of setting tetrode share voltage and setting tube voltage, the comparator 11 turns off the switching circuit 2 when series- capacitor-charging voltage arrives at the sum voltage of these setting tetrode share voltage and the tube voltage.

Filed: 1986-01-10
Abstract: PURPOSE:To protect an amplifier from the temperature rise together with a transient rise by obtaining a power consumption from a voltage fed to a power device and a current flowing therethrough and calculating a transient temperature change from the power consumption. CONSTITUTION:When a power amplifier 7 outputs a transmission signal, a current signal vI and a voltage signal vV are outputted respectively from a current detection circuit 1 and a voltage detection circuit 2, a multiplication circuit 3 makes operation of P=vIXvV to obtain a power consumption P of a power transistor (TR) Q1. A junction temperature calculation circuit 4, based on a transient heat resistance or the like of the TR Q1 and the power P, makes an operation to obtain the transient response of the temperature of the junction of the TR Q1. When the transient response exceeds the normal operating range of the TR Q1, a junction temperature discrimination circuit 5 outputs a fault signal, which operates an operation control circuit 6 thereby protecting an amplifier 7 from the temperature rise. Thus, the power amplifier is protected from the temperature rise together with the transient rise.
