Title: Chuck for wafer
Inventor: TAKAHASHI KAZUO
IPC: B23Q3/08
Filed: 1988-03-11
Abstract: PURPOSE:To suck a wafer successively from the center in the outer circumferential direction of the wafer to enable correcting a plane shape of the wafer while plane-sucking the deformed wafer by increasing the ratio per unit area of a wafer contact section to a wafer noncontact section with the top face of a wafer loading base in the outer circumferential direction of the wafer. CONSTITUTION:Vacuum grooves 5 as noncontact sections with a wafer are formed among each island 2, and a plurality of the vacuum grooves 5 are shaped concentrically and radially to the center of a wafer loading base 1 and communicate mutually, thus forming the shape of the islands 2 to a fan shape. The wafer contact areas of the top faces of the islands 2 are increased generally toward the islands on the outer circumference of a wafer chuck. The value acquired by dividing the wafer contact areas by wafer noncontact areas is elevated toward the outer circumference of the wafer chuck. A plurality of suction ports 4 are shaped into the vacuum grooves 5, and the wafer is sucked and fixed. Frictional force is reduced toward the outer circumferential direction of the wafer in such as island chuck, thus easily correcting the wafer to a plane shape.

Title: Rotor of induction motor
Inventor: SHIMAMOTO KOUJI
IPC: H02K17/16
Filed: 1983-04-04
Abstract: PURPOSE:To reduce vibration and noise when operated with an inverter by reducing the stack thickness of a rotor smaller than that of an armature, and providing an annular magnetic member in a shortcircuiting ring of the rotor to form a leakage magnetic flux passage. CONSTITUTION:The stack thickness l8 of a rotor core 8 of an induction motor is reduced smaller than the stack thickness l2 of an armature core 2, and an annular magnetic member 40 which is formed by cutting from a cylindrical member of a material having large magnetic permeability such as a silicon steel is engaged with the outer periphery of a shortcircuiting ring 9c provided in a squirrel-cage winding 9 of the core 8. Accordingly, when a 3-phase AC is supplied to an armature winding 4, a magnetic flux which passes through a magnetic member 40 does not cross the winding 9. Thus, it becomes leakage magnetic flux, thereby increasing the leakage reactance. In this manner, the vibration and the noise when a motor is operated with an inverter having large output waveform distortion can be readily reduced.

Abstract: PURPOSE:To restrain minority carriers from being injected into a substrate by installing a back gate bias voltage generation circuit composed of a feedback means which controls an output of a driving means on the basis of a detection output of a minority-carrier detection means. CONSTITUTION:A minority-carrier detection means 14 provided with a collector electrode structure is installed around an impurity diffusion region of a transistor which forms a rectification means 13. As a result, even when a potential of the impurity diffusion region becomes lower than an output voltage of the rectification means 13 by any cause and minority carriers e<-> caused by a parasitic diode of the rectification means 13 is leaked to a substrate, the minority carriers e<-> are captured and detected by using the minority-carrier detection means 14. A driving voltage of a driving means 12 can be lowered by a control voltage on the basis of a detection data of the minority-carrier detection means 14. Thereby, it is possible to reduce a potential difference which is applied to the parasitic diode of the rectification means 13 and to restrain the minority carriers e<-> from being injected into the substrate.
