IPC: D05B35/08
Filed: 1988-10-31
Abstract: PURPOSE:To make it easy to alter a dart depth of dart sewing in every number of sheets or every one time by providing a movable mechanism which makes it possible to turn a movable base-plate and by providing a controlling mechanism which adjustably alters a stopping position of the movable base-plate at plurality of specified position by means of the movable mechanism. CONSTITUTION:When a first switch 25 provided on a mounting base-plate is pulled up, its port, OUT 1, is connected to a port, OUT, of a switch 26 and by operating the switch 26, its ports, OUT and IN, are passed through. The air is thus led into a chamber on the right side of an air cylinder 24 from an air source 7 through the OUT port of the switch 26 and the OUT 1 port of the switch 25 and then a speed control valve 29. In this way, since a piston rod is retracted and a movable base plate is turned, a metal fitting 23 for setting a position contacts to a position-adjusting screw 22, and a dart depth of dart sewing is thus made shallow. On the other hand, when the switch 25 is pushed down, the air is led into a chamber on the left side of the air cylinder 24 through a speed control valve 28. In this way, since the piston rod is extended and the movable base-plate is turned, the metal fitting 23 contacts to a position- adjusting screw 21, and a dart depth is thus made deep.

Title: Intermediate voltage generation circuit
Inventor: MORI SHIGERU
IPC: G11C11/407
Filed: 1992-10-14
Abstract: PURPOSE:To enable restoration even when an output voltage fluctuates from a stipulated level by providing two internal voltage output stages and lowering output impedance. CONSTITUTION:When the output voltage VOUT is turned lower than 1/2VCC, a transistor Q5 is turned on. Thus, the voltage level of a node NO5 is lowered and the transistor Q7 is turned on and then is operated so as to turn the output voltage VOUT back to the voltage level of 1/2VCC, through an intermediate voltage output stage 3a. At this time, the transistor Q8 is automatically turned on 2 and is operated so as to turn VOUT back to the voltage level of 1/2VCC through the intermediate voltage output stage 3b. At this time, the ratio of a current ia flowing through the intermediate voltage output stage 3a to VOUT and the current ib flowing through the intermediate voltage output stage 3b to VOUT is equal to the ratio of the transistor sizes of Q7 and Q8. Thus, by making the transistor size of Q8 larger than the one of Q7, the output impedance at the time of the fluctuation of the output voltage can be lowered.

Title: Detecting method for positional deviation
Inventor: FUJII KIYOSHI
IPC: G01B7/00
Filed: 1989-10-25
Abstract: PURPOSE:To obtain an accurate positional deviation detecting method by forming an index mark at a predetermined position on a workpiece, and measuring a tunneling current or an electric field electron emission current flowing between the mark and a predetermined position on a mask. CONSTITUTION:An electrode 9 secured to a mask stage 10 is brought into contact with a metal electrode 8 on a mask to be conducted, and connected to the positive terminal of a DC power source 12. A workpiece 6 is conducted from a rear surface with a board stage 11, and connected to a micro current measuring unit 13. A voltage is applied from the source 12 between the workpiece 6 and a metal stylus 7 formed on a X-ray mask 4. When it is approached to a distance of several nanometers, a tunneling current flows between both. Since the current is exponentially varied with respect to the distance between the both, the relative position between the uneven mark 16 formed on the workpiece 6 and the stylus 7 on the mask 4 can be detected with high resolution. An interval can be accurately set by equalizing the length of the stylus 7 to the gap between the mask 4 and the workpiece 6.
