Title: Forward movement device for juxtaposed work
Inventor: ADERUBERUTO RAUFUAA
IPC: B23D47/04
Filed: 1988-06-29
Abstract: PURPOSE: To cut even short workpieces into desired length by bringing a plurality of workpieces of different length placed side by side, into pressure contact with a stopper by a device provided with a slider, to array the workpieces, and cutting them with a circular saw. CONSTITUTION: When a slider 12 advances in a feed direction R and the front ends of segments 21 come in contact with the segment side members of workpieces W, reaction brought about by a chamber (gas spring) 20 is larger than the force required to feed the workpieces W, so that the workpieces W are fed in a feed direction. Since the mutual spacing of the respective segments 21 is small, the workpieces of small diameters can be fed. At the time of arraying the workpneces different in length, the segments 21 are successively made to act upon the workpieces so as to be moved in the direction of a stopper. As soon as the front end of the longest workpiece W1 reaches the stopper, the segment 21 moves in an opposite direction to the feed direction and enters the chamber 20. When three workpieces come in pressure contact, the slider is stopped by a switch 32 to cut the workpieces.

Title: Porous static pressure guide
Inventor: KANAI MUNENORI
IPC: C23C18/31
Filed: 1987-06-29
Abstract: PURPOSE:To make it possible to obtain desired resistance of a passage by providing electroless plating matted material in porous substance used for a static guide which holds a space between a male screw and a female screw. CONSTITUTION:Porous substance used for a static guide which holds a space between a male screw and a female screw is subjected to electroless nickel plating. Plating liquid passing the inside of the porous substance flows from a flow-in side 39 to a flow-out side 40 to minimize the resistance of a passage. Consequently, the plating liquid concentrates in a rather thick fluid passage 37 in the porous substance and a plating film 41 is formed into further deep portion, but in rather a narrow fluid passage 38 it is limited to a surface layer plating film 42 so that fluid resistance is equalized. The passage resistance of the porous substance can be accurately controlled by adjusting the quantity of the entire plating.

Title: Drive device for motor
Inventor: TAKAHASHI TSUNEO
IPC: G11B19/28
Filed: 1982-09-14
Abstract: PURPOSE:To prevent a motor from reversely rotating with a simple structure without using a reverse rotation detecting sensor or the like by detecting the presence or absence of a reference clock signal, and rapidly stopping the drive of a motor when the clock signal is defective. CONSTITUTION:When a reference clock signal is applied to a terminal A, it is detected at the point B by a diode 12 and a condenser 13. When the values of the condenser 13 and resistors 11, 14 are set so that the voltage at the point B becomes the voltage for turning ON a transistor 16, i.e., VBE or higher at the normal reference clock signal inputting time, the voltage at the point C becomes L level. If the clock signal is defective, the voltage at the point B decreases, the transistor 16 is turned OFF, and the voltage at the point C becomes H level. When the output level of the point C is used for the ON and OFF signal of a switch 4, it can prevent the motor 4 from reversely rotating when the clock signal is defective, thereby stopping the motor.
