Patent JP-H0254310-A (JP)
Title: Numerical controller for drilling
Inventor: NAKAHARA TSUTOMU
IPC: G05B19/4155
Filed: 1988-08-19
Abstract: PURPOSE:To omit the labor and the time required when the deviation value is set and changed and to improve the cutting accuracy by performing each time the correcting arithmetic applying deviation value produced actually for the drilling control via a correcting part. CONSTITUTION:When a drill 11 touches the surface of a work, a signal SC is produced and invalidated by a data processing part DP2. Then a contact signal processing part SP8 stops temporarily an interpolator IC4 to stop the feed of the drill 11. An interpolating part RS9 reads the deviation value Z2 out of a servo control part CT5 and corrects the cutting value Z2 into Z2-DELTAZ2. This corrected value is stored in an information storing part DM3 and updated. Then the part DP2 sends the value Z2-DELTAZ2 and the feed speed F2 via the part DM3. Thus the IC4 moves the drill 11 to a cutting surface 13. When a cutting process is over, the DP2 instructs the stop of the time T with the signal of the IC4. The IC4 reads the total shift value measured from a start point 21. The return value Z3 and the feed speed F3 are obtained from the total shift value and supplied to the part DM3. Then the IC4 is started and the drill 11 is moved back to its start point.

Title: Hydraulic buffer
Inventor: MIZUTANI YOICHI
IPC: F16F9/46
Filed: 1989-08-09
Abstract: PURPOSE:To reduce the weight of a hydraulic buffer by a method wherein a piston rod is formed of a pipe while the pipe is enlarged in diameter at a piston part, the piston rod is equipped with a communicating path between a piston upper chamber and a lower chamber, and a synthetic resin ring having low friction coefficient is closely attached to the outer periphery of the piston part. CONSTITUTION:During shrinking process, a piston part 22 and a piston rod 21 enter an inner cylinder 1, and a part of oil in a piston lower chamber 1c flows into a piston upper chamber 1b from a communicating hole 24 while remaining oil operates an attenuation power generating mechanism 38 from an oil path 26 and a passage 31 to generate attenuation power to be stored in an accumulator 11. During stretching process, the piston rod 21 protrudes from the inner cylinder 1 and an outer cylinder 2 and pressure oil in the upper chamber 1b flows into the lower chamber 1c from the communicating hole 24 as well as oil in the accumulator 11 flows into the lower chamber 1c. Thus even if the diameter of the piston rod 21 is large, increase in weight is small owing to a thin pipe, thereby increasing support weight with hydraulic pressure unaltered.

Title: Automatic drain apparatus in fuel or waste oil tank
Inventor: TANDA KUNIHARU
IPC: B01D17/12
Filed: 1984-10-03
Abstract: PURPOSE:To dispense with manual work, by automatically detecting the drain flowed into an oil-water detection box by using an oil-water detection sensor and inhibiting the inflow of an oil component while allowing only moisture to flow in to entirely flow the same over a barrier plate. CONSTITUTION:When a valve 2 is opened by a solid-state timer, a drain is flowed into the detection chamber 6 of an oil-water detection box 3 and an oily component or moisture is detected by an oil-water detection sensor and, when the oily component was detected, the valve 2 is closed to allow the timer to count and, when moisture was detected, it is succeedingly flowed in as it is to overflow a barrier plate 5 and flowed into a discharge chamber 7 to be discharged from a discharge pipe 20. Detection is repeated during the set time of an IC timer or until a lead switch 12 is closed and, thereafter, the timer is reset and again begins to count.

Title: Constant current circuit
Inventor: SANO YOSHIAKI
IPC: H03F1/30
Filed: 1983-11-02
Abstract: PURPOSE:To obtain a constant current circuit possible for selecting an optional and desired temperature coefficient and less in the fluctuation of a power supply voltage by combining two circuits where the temperature coefficient of flowing current has a positive and a negative value. CONSTITUTION:The emitter area of transistors (TR) Q1, Q2 and Q3 is manufactured identically, and that of a TRQ4 is manufactured (n) times that of them. Through the constitution shown in Fig., a current I2 is given as I2=(kT/qR2)ln (n) and on the other hand, a current I3 is expressed approximately as I3 VBE/R3. Since the voltage VBE has a negative temperature coefficient, the current I3 has a negative temperature coefficient. Thus, a constant current output I0=I2+I3 is the sum of currents of the positive and negative temperature coefficients and the temperature coefficient of the current I0 is set bipolar by setting optionally the ratio of the currents I2 and I3. Then the current I2 is independently of a voltage Vcc and the current I3 is affected very slightly of the current I1 depending on the voltage Vcc, then the effect of power supply voltage fluctuation is not almost caused.

Title: Method for removing cut hip from drill
Inventor: YOKOI MASAHIRO
IPC: B23B47/34
Filed: 1990-08-03
Abstract: PURPOSE:To remove cutting chips that twined around a drill without preparing any cutting chip removing member by pulling out the drill from a work each time drilling work is completed and rotating it at swift acceleration in a direction opposite to that of processing time. CONSTITUTION:A drill 6 rises till a specified height when the depth of a hole reaches a specified depth and processing is completed. Here, when it is rotated at swift acceleration and at high speed in a direction opposite to that of cutting time after the rotation of the drill 6 is once stopped, the cutting tips 10 twined around the drill 6 cannot follow the rotation of the drill 6 and attempt to stay at the place, however, downward force that works along the side face of a relief groove acts on them by the rotation of the drill 6, and slip off below in a moment from the drill 6 along the relief groove. In an example of a case where a work 9 is S45C, after cutting work is completed, reverse the drill 6 at high speed by swift acceleration to raise rotation speed after the rotation of the drill 6 is once stopped.
