Abstract: PURPOSE:To obtain a rotary polygon mirror of synthetic resin having low-cost reflecting mirror surfaces which has superior surface accuracy by mass- production by specifying the diameter of a pin point gate according to its polyhedral shape. CONSTITUTION:Pin point gates 20 as many as mirror surface parts 11 are set and weld lines are formed almost at intersections of the respective mirror surface parts 11 without any hindrance to reflection utilization surfaces of the rotary polygon mirror, while resin pressure applied to the respective mirror surface parts at the time of injection molding is made uniform. Here, let d=logL+ or -0.2mm, where L is the length of the mirror surface parts 11 and (d) is the diameter of the pin point gates. Consequently, the proper gate diameter is set accurately and immediately according the length of the reflecting mirror surfaces and reflecting mirror surfaces with invariably high accuracy are molded by injection.

Title: Apparatus and method for measuring semiconductor device
Inventor: HIRAI TAKEHIRO
IPC: H01L21/66
Filed: 1989-07-19
Abstract: PURPOSE:To perform highly accurate measurement by detecting the contact state of a probe needle and an electrode part on the basis of an electrical reflection coefficient and controlling the contact state so as to obtain the same value. CONSTITUTION:In this measuring apparatus, the contact state of a contact state detecting probe needle 6 and a contact state detecting electrode 7 is measured, for example, by a voltage reflection coefficient measuring apparatus 8. It is judged whether the value of the measured voltage reflection coefficient shows the value alpha in such a case that the contact state of the contact state detecting probe needle 6 and the contact state detecting electrode 7 is proper. When the value does not show the proper value alpha, the contact state of a measuring probe needle 4 and a measuring electrode 5 is not proper and, therefore, a wafer stage 2 raised or lowered by a wafer stage controller 9 in order to change the contact state. When the value becomes the proper value alpha, desired measurement is performed by various measuring devices through the measuring probe needle 4.

Filed: 1987-07-27
Abstract: PURPOSE:To well suppress an unnecessary signal with simple constitution by controlling an input signal based on the residual difference to a value predicted by using a predicting filter. CONSTITUTION:An input acoustic signal (input terminal 1) is supplied to the predicting filter 4, and a residual difference for the input acoustic signal to a value predicted by the filter is obtained, to control (variable gain control circuit 2) an input acoustic signal based on the said residual difference.
