Title: Wafer positioning apparatus
Inventor: SHIGEHATA SHIYUUICHI
IPC: H01L21/68
Filed: 1989-09-06
Abstract: PURPOSE:To surely convert an image of a wafer into a binary-coded value without being influenced by a surface state of the wafer such as a reflected light and to smoothly process the image by a method wherein an illuminant is placed in a background and a shadow of the wafer is picked up by using a television camera. CONSTITUTION:Images of positioning marks M1, M2 of a transparent cover 23 are picked up by using a television cameral 11; the central position of a wafer holder 22 is found; an instruction to position an xytheta table in the origin for an x-axis, a y-axis and a theta-axis is sent. Then, a wafer 21 is placed on the wafer holder 22; a shadow of the wafer 21 is picked up by using the television camera 11; a displacement from the origin and an angle of rotation are found; an operating instruction is sent to an xytheta table controller 15; a direction and a position of the wafer 21 are decided. When a positioning operation is finished, the shadown of the wafer 21 is picked up again. When the position and an angle error are not within a definite range, a correction signal is sent to the xytheta table controller 15 and a correction operation is executed until they are set withing a preset range. Thereby, it is possible to surely process the image of the wafer 21 without being influenced by a reflection state of the wafer 21.

Title: Loading device, unloading device, and attaching and detaching device for memory cartridge
Inventor: ORIMOTO MASAAKI
IPC: G06K17/00
Filed: 1988-09-19
Abstract: PURPOSE:To improve the operability to surely load or unload a memory cartridge by combining a frictional feed means and an engaging feed means to load or unload the memory cartridge. CONSTITUTION:At the time of loading a memory cartridge 10, the memory cartridge 10 is pulled to the vicinity of a connector 26 by a frictional feed means 70 and is pressed into a connector 26 by the engaging means. The frictional feed means 70 drives a pressing member 76, which presses the memory cartridge 10 so that a prescribed frictional force is caused, in the direction of memory cartridge insertion by a motor to draw in the memory cartridge 10 by the frictional force. Consequently, when the memory cartridge 10 is reverse inserted, the load of the memory cartridge 10 is larger than the frictional force to cause slip, and the memory cartridge is not drawn in more than necessary. Thus, the memory cartridge is surely loaded and unloaded with a good operability.

Title: Device and method for logic composition
Inventor: OSUGA HIROSHI
IPC: G06F17/50
Filed: 1992-09-01
Abstract: PURPOSE:To provide the device and method for logic composition which can generate such a logic circuit that a fault detection rate becomes high without inserting a scanning circuit for fault simulation when the input/output pattern of a function table is used as a test pattern. CONSTITUTION:When logic is composed on the basis of function specifications, a logic cube selecting means 132 selects a way of taking a logic cube out of the function table. As for the selected logic cube, an evaluated quantity calculating means 133 finds a fault detection rate when the input/output pattern of the function table are used as a test pattern. Consequently, the logic circuit which can obtain a high fault detection rate in logic verification can be generated. An increase in area as a result of the insertion of the scan circuit is therefore suppressed. Further, no scanning circuit is inserted, so the test time can be prevented from becoming long. Further, an increase in circuit delay is precluded.

Abstract: PURPOSE:To adjust temperature coefficient in a desired range in such a manner as to eliminate the need for additional adjustment in another range, by once converting an output voltage from a reference voltage generation source into a pulse signal having a duty ratio according to a selected measuring range. CONSTITUTION:Current flowing through a force coil 1 is converted into a voltage signal with an output resistance R to be inputted into an A/C converter 6. A reference voltage signal to be supplied to the converter 6 is obtained by converting a DC voltage signal from a voltage generation source 10 into a pulse with the opening or closing of a switch element 11 and again, into DC with an LPF9. The opening or closing timing of the element 11 is determined by an output signal from a pulse forming device 12, which outputs a square wave signal with a duty ratio corresponding to selection of a changeover switch 14a from a fixed cycle of signal from a timing signal generator 13. The switch 14a forms a measuring range switching means in linkage with a switch 14b which changes coefficient of an computing section 7. Moreover, as the resistance R is only one, the adjustment of the temperature coefficient will not be deviated regardless of any change in the range only is once done.
