Title: Feeding device for machine tool
Inventor: ABE YOSHINORI
IPC: B23Q1/26
Filed: 1987-09-02
Abstract: PURPOSE:To reduce the abrasion of thread type grooves and rotary bodies by providing a control means for expanding/contracting a piezoelectric actuator in the axial direction of nut members so as to release the increase in axial load between each of thread type grooves and the rotary bodies accompanying the rise in the rotating speed of a driving means. CONSTITUTION:A screw member 13 is rotated in the desired direction by means of a motor 12 to move a feed table 19 together with nut members 14, 15 in the desired direction. At this time, when the rotating speed of the motor 12 is gradually increased, a controller 22 gradually contracts a laminated type piezoelectric actuator 16 in the axial direction making both nut members 14, 15 mutually approach, thereby, gradually reducing the pre-load (f) between each of thread type grooves 13a, 14a, 15a and balls 17, 17.... On the other hand, when the rotating speed of the motor 12 is gradually reduced, contrarily, the controller 22 gradually expands the actuator 16 in the axial direction to gradually increase the pre-load (f). Thereby, the abrasion between each of the thread type grooves 13a-15a and the balls 17 can be reduced at the time of the high speed rotation of the screw member 13.

Title: Logic circuit
Inventor: SAWADA SOSAKU
IPC: H01L27/095
Filed: 1990-08-21
Abstract: PURPOSE:To make it possible to apply a logic circuit to a circuit in a FET system by using the gate of the JFET as the input of the logic circuit and the metallic electrode side of a schottky barrier diode as the output of the logic circuit. CONSTITUTION:When input Din of logic circuit X is at L level, the JFETQ21 is in OFF state and node (y) that is the input of a logic circuit Y is set at H level. Then, since the JFETQ22 is turned on, the node (y) is clamped by the gate source rise voltage VH of the JFETQ22. On the other hand, when the input Din of the logic circuit is at H level, the JFETQ21 becomes conductive. Accordingly, the voltage of node (y) becomes the voltage of a sum of the on voltage between the drain and source of the EFETQ11 and the rise voltage of schottky barrier diode S21. Then, if voltage VL is lower than voltage VH, this circuit becomes an effective logic circuit.

Title: Ink jet recording device
Inventor: MATSUMOTO KAZUAKI
IPC: B41J2/175
Filed: 1989-08-29
Abstract: PURPOSE:To make printing stable and enable high-speed printing by providing a constitution in which a part where the first plate hole is placed over the second plate slit becomes a discharge orifice and ink is supplied to a discharge orifice part through the second plate slit. CONSTITUTION:Ink is supplied to an ink reservoir 7 from an ink discharge orifice 8 in a substrate 1 to the full capacity of the reservoir. In addition, the ink is allowed to flow to a lateral slit 5 from a part where the ink reservoir 7 is placed over the lateral slit 5, then is allowed to flow into a hole 4 to the full capacity via a part where the reservoir 7 is placed over the lateral slit 5. Next, a heating element becomes not, if an electric current is applied to it from an electrode 11. Consequently, the ink which comes in contact with the heating element is thermally evaporated to form vapor bubbles. This process results in the instantaneous squeezing-out of the ink to form splashed ink droplets, which are received on recording paper. Thus printing takes place. After discharging the ink, the heating element cools down and the vapor bubbles are caused to contract and disappear. At the same time, the amount of ink equal to that discharged to the part 6 is allowed to flow in through the lateral slit 5 to restore the state.
