Title: Two-wire bidirectional repeating installation
Inventor: YASUKAWA HIROSHI
IPC: H04B3/23
Filed: 1984-10-11
Abstract: PURPOSE:To equalize two reception levels of an automatic gain control circuit to stabilize the operation by controlling the gain of a variable gain attenuator or a variable gain amplifier, which is inserted onto a transmission line in the four-wire side of a two-wire four-wire converting circuit, with the automatic gain control circuit. CONSTITUTION:Audio signals transmitted from telephone sets 11 and 21 are subjected to the line loss on transmission lines a1 and a2. Reception levels are observed by level detecting circuits 15 and 25, and respective under sound volumes (g) and g' are determined by an automatic gain control circuit 30. Gains of variable gain amplifiers 14 and 24 are equalized to larger one. That is, G=max(g, g') is true, and a variable gain attenuator 17 or 27 on a transmission line b1 or b2 in the four-wire side of the smaller under sound volume between variable gain attenuators 17 and 27 is attenuated by the same quantity as a difference DELTA between under sound volumes, namely, DELTA=g-g'. By this structure, the input reception level of the automatic gain control circuit 30 is made uniform independently of balance or unbalance of the line loss to stabilize the operation of the automatic gain control circuit 30.

Title: Recognizing method of semiconductor manufacturing device
Inventor: YOKOYAMA NAOMI
IPC: H01L21/68
Filed: 1991-08-26
Abstract: PURPOSE:To recognize points on a semiconductor chip in a semiconductor manufacturing device without being affected by the personel errors by a method wherein in a recognizing method of the semiconductor manufacturing device, a decision that the form of a triangle formed by linking recognition points with one another is not remarkable or is not characteristic at all is automatically performed on the basis of the ratio of the length of one side of the triangle to the length of a perpendicular to the side. CONSTITUTION:In a recognizing method of a semiconductor manufacturing device, when the longest side of a triangle formed by line segments connecting recognition points A, B and C is the base BC and a perpendicular drawn to the base BC is AP, the ratio (gamma) of the side to the perpendicular = AP:BC is a condition that a triangle is formed. When the value (gamma) obtained on this condition is a prescribed reference value or higher on the side of the manufacturing device, the triangle is automatically judged to be characteristic and necessary recognition is performed. Thereby, there is no possibility that an irregularity in a decision and a recognition due to the difference among operator individuals is generated and a reduction in a working efficiency due to the stop of the manufacturing device based on an erroneous recognition and defective products can be prevented from being generated.
