Title: Laser beam machine
Inventor: KAJIKAWA TOSHIKAZU
IPC: B23K26/06
Filed: 1989-06-23
Abstract: PURPOSE:To obtain the laser beam machine having high accuracy by providing a driving means for rotating and inclining an optical axis of an optical system, moving a focusing laser light in a plane by this driving means and correcting a working position. CONSTITUTION:A working optical system 2 executes a minute rotation by a piezo-element 4 by using a rotation axis fixed spatially as an axis. A working object is placed on a moving stage 6, and can move in a focal plane of the working optical system 2 by a driving motor 8 controlled by a driving circuit 7. Also, a calibration table is written in advance in a ROM 10, and whenever the moving stage 6 is moved, the position error quantity corresponding to a stop position is read out of the ROM 10 and by driving the piezo-element 4, the position is corrected. In such a way, by using the moving stage 6 whose accuracy is comparatively low and whose cost is low, positioning can be performed with high accuracy.

IPC: C30B23/06
Filed: 1991-06-03
Abstract: PURPOSE:To prevent, in a molecular beam cell for heating a raw material with a ribbon heater, that a part of heater warps toward outside due to thermal expansion when it is in contact with a reflecting plate provided at a side of the heater, resulting in short-circuit when the ribbon heater is partly in contact with a through hole of a heater support. CONSTITUTION:Individual belt-shaped current path 9 of a ribbon heater 1 is warped and bent transverse to the longitudinal direction in order to enhance rigidity in the longitudinal direction. Due to a high stiffness, the belt-shaped current path 9 of ribbon heater never warp toward inside or outside, even when it is thermally expanded.

Filed: 1983-09-02
Abstract: PURPOSE:To damp the vibration of a carrier without being affected by the inertia of the carrier itself, by providing a delaying means for delaying a driving current supplied to a motor for driving the carrier. CONSTITUTION:When the absolute value of a positional error is largest in a predetermined range, a positional error latch converter 20 outputs signals X, Y and Z for the period of time for which a signal I is inputted, and when the absolute value is smallest in the predetermined range, the converter 20 outputs the signal X for said period of time. On the other hand, a timer 22 generates an output signal for a predetermined period of time on being triggered by the trailing edge of a signal from an AND gate 18. Therefore, at times other than the time of an initilizing operation, the output signal from the timer 22 is inputted into an OR gate 23, and a signal X1 is inputted into a designated current delaying circuit 21 for a predetermined period of time. Accordingly, the value of a driving current supplied to the motor 1 gradually increases from 0, so that the vibration of the carrier can be securely damped.

IPC: B21H1/18
Filed: 1985-07-23
Abstract: PURPOSE:To obtain a cylindrical member being free from an underfill part and a burr, etc., by controlling a penetration quantity of a pair of mandrels, based on a difference of a proceeding condition of a plastic deformation of both side end parts, when bringing the cylindrical member to plastic working from a columnar billet.

Each detector 18 is connected to a control device 19 for controlling an operation of a mandrel driving device 15 for driving a pair of mandrels 14, respectively. In case a proceeding state of a plastic deformation of the left end side of the columnar billet 2 is faster than that of the right side, a detected light quantity by the light quantity detector 18 of the left side becomes larger than that of the right side. In this case, a penetration quantity of the mandrel 14 of the right side is set so as to be more than a penetration quantity of the mandrel 14 of the left side, and a part of the billet 2 is made to flow to the side where the proceeding state of the plastic deformation has been delayed.

Abstract: PURPOSE: To improve drivability of an engine used with kerosene fuel or the like of low volatility, by the charging method of downward inversion scavenging, in which imperfectly vaporized liquid drop fuel is promoted its evaporation and vaporization by heat exchange on the top surface of a piston.  
     CONSTITUTION: Residual gas in the preceding cycle in a cylinder is rapidly moved to the side of an exhaust port 2' at the beginning of opening of an exhaust valve 2, and cancelled by a downward gas flow component following up to a piston because the piston 1 is on the way of lowering motion at the final period of blow down, then a gas flow is moderated. Scavenging air is mostly inverted its motion in a lower down stroke of the piston 1 further on top surfaces of the piston and fed into the cylinder, then the top surface of the piston is fully cooled by the scavenging air, further the scavenging air is decelerated in a  process when colliding against the piston surface and inverted, thus an excessive amount of swirl is not caused.
