Title: Instrument for analyzing surface of semiconductor substrate
Inventor: KONAKAWA YOSHIKO
IPC: G01N23/22
Filed: 1992-06-09
Abstract: PURPOSE:To improve the ability of the instrument for qualitatively and quantitatively analyzing the surface of a semiconductor substrate for contaminants by making primary X rays from a plurality of X-rays generators incident to nearly the same area on the surface of the semiconductor substrate. CONSTITUTION:Incident X rays 5-1, 5-2, and 5-3 the incident angles of which to a semiconductor substrate 2 are controlled to low angles are made incident to nearly the same incident section 2a on the surface of the substrate 2. Most of the X rays 5-1, 5-2, and 5-3 are reflected by the surface of the substrate 2 as reflected X rays 6-1, 6-2, and 6-3, but only an extremely limited amount of the X rays intrude into the surface section of the substrate 2 and is diffused into or adhere to the material and surface of the substrate 2. As a result, contaminant elements near the surface section of the substrate 2 are excited and fluorescent X rays 9 having large energy values against noise are generated from the contaminant elements. The X rays 9 are detected by means of a detector 9 and qualitatively and quantitatively analyzed and, as a result, the contaminant elements are detected.

Title: Antenna for automatic tracking device
Inventor: SUZUKI HIDEKI
IPC: H01Q3/00
Filed: 1995-06-16
Abstract: PURPOSE: To simplify the structure of the antenna and to improve the gain of a tracking use primary radiator by fitting the tracking use primary radiator to the antenna at a same angle as that of a main channel use primary radiator. CONSTITUTION: A main channel use primary radiator 2 is arranged in the middle of a parabolic antenna 1 and four tracking use primary radiators 3 are fitted as a same angle as that of the main channel use primary radiator 2 to the parabolic antenna at upper/lower/left/right positions of the radiator 2. When a signal source is in existence in front of the parabolic antenna 1, the four tracking use primary radiators 3 receive a signal of the same level. Furthermore, when the signal source is located above with respect to a face of the parabolic antenna 1, for example, the signal is focused at a position lower than the main channel use primary radiator 2 by the parabolic antenna 1. Thus, the electric field strength of the tracking use primary radiators 3 fitted to the lower side is stronger and the direction of the signal source is recognized.  When the signal source is in existence in a direction of lower/left/right with respect to the face of the parabolic antenna 1, the direction of the signal source is recognized by the same operation as above. Since the gain of the tracking use primary radiators 3 is increased, the sensitivity of the tracking device is improved.

Title: Power source and arc generator
Inventor: SATO RYODA
IPC: H02M9/00
Filed: 1991-05-23
Abstract: PURPOSE:To properly use a single-phase AC to meet characteristics of a load and to improve a power utility efficiency by converting in ranges of each phase by different power converters. CONSTITUTION:A phase controller 110 of a first power converter 101 supplies only a part of 0-60 deg. of a sine wave of each phase to primary coils 151-153, and outputs a single-phase AC from a secondary coil 154 through a transforming section 150. Similarly, second, third power converters 102, 103 output only parts of 60-120 deg., 120-180 deg. of the sine wave of each phase. Since a frequency of three times as large as that of the three-phase AC of the primary side is obtained as each single-phase output of a secondary side, the welding speed becomes, if it is used for an arc welding, etc., three times. Since the output of the converter 103 is a sawtooth wave which abruptly rises and becomes zero in a drooping state, an arc is easily obtained at the time of arc welding, and a stable arc is obtained.

Abstract: PURPOSE:To recognize the state of a telephone set terminal efficiently by providing a database storing a data representing a current state of each telephone set terminal and reading the content of the database corresponding to a telephone set terminal on request when a service request comes from the telephone set terminal so as to inform it to the telephone set terminal on request. CONSTITUTION:When a service request is given to a system control section 5, the section 5 confirms it that a telephone set terminal on request 2 is available of the request and sends a signal representing the permission of the service request to the telephone set terminal 2. Then the operator of the terminal equipment 2 dials a telephone set terminal of service request destination, that is, a telephone set terminal number whose current state is desired to be recognized. When the request destination is a telephone set terminal 3 and its number is 001, the control section 5 retrieves a database 6 corresponding to the terminal equipment 3, reads the information and sends it to the terminal equipment 2. Thus, since the information representing the current state of the terminal equipment 3 is displayed onto a display device or the like provided to the terminal equipment 2, the operator resident at the terminal equipment 2 recognizes the state without calling the terminal equipment 3.

Filed: 1993-06-22
Abstract: PURPOSE:To eliminate the need for the output pin for testing and to improve system operation speed by connecting a node where output data are output and a node where reference data are output. CONSTITUTION:After a reset signal RST- is negated, output data are stored in FF41 at the leading edge of a clock CLK and at the same time reference data are stored at FF42. Q output is connected to Q output and Q- output is connected to Qoutput in the FF41 and FF42. When the output data and reference data stored at the FF41 and FF42 differ, current flows between the output of FF41 and FF42. The fluctuation in the voltage between a power supply pin and a ground pin is monitored externally and conformance and non-conformance of the data stored at the FF41 and FF42 are detected according to the voltage fluctuation. The outputs of FF41 and FF42 are connected by a plurality of lines to prevent misjudgment of conformance and non-conformance due to the failure in a failure diagnostic circuit itself, namely the disconnection of line.
