Title: Over voltage protection system of parallel operation system
Inventor: SHIMAMORI HIROSHI
IPC: H02M3/28
Filed: 1990-11-08
Abstract: PURPOSE:To realize over voltage protection while keeping redundancy of parallel operation by providing a comparing means which generates an over voltage decision signal when a voltage obtained by rectifying and smoothing an impulse, obtained in the secondary side of a transformer of each power supply unit, in addition to a DC output, has exceeded the reference voltage. CONSTITUTION:When a fault where a resistor R1a of a power supply unit 30a becomes open is generated, an output voltages Vo1, Vo2 rise and a partial voltage of output voltages Vo1, Vo2 exceed the reference voltages Vref 2a, Vref 2b. In this case, comparators 15a, 15b generates an over voltage detecting signal. Moreover, with rise of the output voltage Vo1, the voltage Vc1a rises and a partial voltage of the voltage Vc1a exceeds the reference voltage Vref 3a and a comparator 31a generates an over voltage decision signal. On the other hand, since the PWM circuit 12b executes the control operation to lower the output voltage Vo2, the voltage Vc1b is lowered and the comparator 31a does not generate the over current decision signal and the PWM circuit 12b continuous operations.

Title: Step difference measuring apparatus
Inventor: TAKASU NOBORU
IPC: G01B21/02
Filed: 1987-12-02
Abstract: PURPOSE:To achieve a higher measuring accuracy, by mounting a load sensor on the reference pawl to check whether a reference pawl abuts evenly with an object to be measured. CONSTITUTION:When the tip of a reference pawl 13 abuts against an object 2 to be measured placed on a carrier 1 to press the object 2 being measured by an energizing force of a first spring 6, a tension stress on the top surface of the object 2 being measured while a compression stress on the undersurface thereof appear. Deformations of parts 13c orthogonally crossing in pairs of reference pawls 13 arranged respectively on the right and the left caused by these stresses are detected with strain gauges 14, signals of which are amplified to be inputted into a judging unit 1. At this point, when the object 2 being measured is placed aslant on a stand 1, the reference pawls 13 fail to abut the object 2 being measured evenly, which causes a difference of a load on the reference pawls 13. As the difference can be detected based on a difference in signals from the strain gauges 14, it can be determined whether the object 2 being measured is placed exactly on the stand 1. Thus, a highly accurate and reliable measurement is achieved by employing a measured value only as given when the reference pawls 13 abut against the object 2 being measured evenly.

Title: Projection aligner
Inventor: YASUDA MASAHIKO
IPC: H01L21/027
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a projection aligner which can provide good projection of a mask pattern by lightening a warpage of a mask caused by its own weight and a thermal deformation thereof. SOLUTION: A mask 10 is fixedly sucked by a sucking device 14 onto a mask holder 12 made of material, having the same thermal expansion coefficient as the mask and having a constant thickness. Since the absorption surface of the mask holder 12 is flat, the mask 10 is contacted with the surface of the mask holder 12 over substantially the entire surface except for sucking grooves, thus lightening deformation of the mask caused by its own weight. Even when exposure light is illuminated from a light source 18 to cause the temperature of the mask 10 to increase, the heat to the mask is transmitted to the mask holder 12 to cause the temperature of the older to increase. Because of the same thermal expansion coefficient in both the mask and the holder, the heat of the mask 10 is property transmitted to the mask holder 12, so that the mask 10 and the mask holder 12 can have substantially the same level of thermal deformation caused by the temperature change, thus lightening even the thermal distortion of the mask 10.
