Title: Gun drill
Inventor: KURODA SHINJI
IPC: B23B51/06
Filed: 1987-11-26
Abstract: PURPOSE:To enable a great amount of cutting oil to be efficiently discharged without impairing the stiffness of a solid tip by arranging a line segment connecting points which are most apart each other on the periphery section of an oil hole in an ellipse form in such a way as to be perpendicular to the radial direction of a tool main body. CONSTITUTION:An oil hole 17 formed at the center of an oil feeding port 16 is of an ellipse in cross section the minor axis of which is arranged toward the radial direction of a solid tip 11. As a result, a line segment connecting points which are most close each other on the periphery section of the oil hole 17 is in the direction perpendicular to the radial direction of the solid tip 11. Since the oil hole 17 is formed into an ellipse form in cross section as set forth herein above, the hole will never interfere with a feeding port 15, and the oil hole 17 can thereby be made efficiently large in a cross sectional area. In addition, since the minor axis of the oil hole 17 is arranged in the radial direction of the tip, even if the dimension E of the major axis of the oil hole 17 is set to be large in order to obtain a necessary cross sectional area, the periphery section of the oil hole 17 will never come close to the rake face 13a of the solid tip 11, and the stiffness can thereby be maintained, which sufficiently withstands the principal component of cutting resistance. The solid tip can thereby be effectively used for high speed cutting.

Abstract: PURPOSE:To carry out the temp. control of glow plugs simply and securely by providing a switching means for the combined use of one temp. measuring resistor by glow plugs, in a device having a combustor in which glow plugs for vaporization and ignition of fuel are provided. CONSTITUTION:When an engine is started with a main relay 8a and relays 2b, 3b turned on, the temperatures of glow plugs for vaporization and ignition rise rapidly with their respective resistor lines 2a, 3a being electrified. After a certain time has elapsed, a controller 7 turns off the relay 3b, feeding a current to the resistor line 3a only through a power limiting resistor 3c, while cutting off the feed from a measuring series resistor 7a.

Title: Method and apparatus for measuring neutron
Inventor: UEDA KIYOSHI
IPC: G01T7/00
Filed: 1992-11-10
Abstract: PURPOSE:To accurately find a neutron counting rate by removing a neutron background counting rate from a neutron counting rate obtained with reference to at least two conditions whose response characteristic to neutrons from a neutron-radiating body is different. CONSTITUTION:A neutron detector 3 is arranged at the inside of a polyethylene member 7. A core element, i.e., a square tube 8, is arranged between a neutron- radiating body 2a and the detector 3. The response characteristic of the detector 3 to neutrons from the radiating body 2a is changed by filling water into the inside of the tube 8 or by emptying the inside. On the other hand, the response characteristic of the detector 3 to background neutrons from a neutron-radiating body 2b is hardly changed by whether water exists inside the tube 8 or not because the volume ratio of the tube 8 to the member 7 is small. Thereby, respective neutron counting rates with reference to both measuring conditions can be computed by a true neutron radiation intensity from the radiating body 2a, a neutron radiation intensity from the radiating body 2b and a proportional coefficient.

CONSTITUTION:A synchronization acquisition section 14 obtains a frequency spectrum of an inverse spread signal at a frequency band Bx in which a frequency shift  fd caused by the effect of Doppler effect or the like from a digital signal of the inverse spread signal is allowed for each data period of an information data D, a discrimination circuit 14 uses a frequency of a spectrum in excess of a prescribed value as a control signal and gives it to a correction circuit 15, and the oscillating frequency of a local oscillator 4 is adjusted so that the frequency of the inverse spread signal is always equal to a center frequency f1 of a band pass filter 10. Thus, even when the reception frequency is changed due to the effect of Doppler effect or the like, the original information data is demodulated without deteriorating the S/N.
