Title: Method of detecting heat-generating part of semiconductor integrated circuit
Inventor: HAMAGISHI KENJI
IPC: G01R31/26
Filed: 1991-12-18
Abstract: PURPOSE:To detect the highest heat-generating part and the abnormally heat- generating part on the surface of an IC chip by a method wherein the IC chip is cooled down by flowing cooling gas against it, frost is formed on the surface of the IC chip, then an electric current is applied to the IC chip, and the heat- generating part is defrosted. CONSTITUTION:Cooling gas is blown against an IC chip 1 using a cooling spray 6 after opening or before hermetically sealing the package of the IC chip 1, the surface of the chip 1 is cooled, and frost 3 is generated on the surface of the IC chip 1. Then, when an electric current is applied to the IC chip 1 from a power supply 7, the frost 3 only on the heating part 4 of the IC chip 1 is melted. At that time, when the surface of the IC chip 1 is observed by a microscope 5, the circuit pattern on the surface of the IC chip of the heating part 4 where the frost is melted can be seen, and the other part is looked white by the adhesion of frost. Accordingly, the heating part 4 can be specified clearly and discovered easily.

Abstract: PURPOSE:To dispense with a cooling mechanism and make it compact and efficiently and quickly radiate the heat generated by extending a lead, which is connected from the side of resin to the electrode of a semiconductor chip, in front or rear of a heat sink or at the side of it. CONSTITUTION:A lead frame 30 is loaded, through an insulating film 20, at the center of the topside of a heat sink 10.

Title: Attitude controller for antenna on moving body
Inventor: HAYASHI TAKESHI
IPC: G01S3/44
Filed: 1990-11-30
Abstract: PURPOSE:To reduce the installation space of the title controller, to simplify attitude correcting operation and to decrease the apparatus cost by correcting the elevation attitude corresponding to the change in roll-angle attitude only when the azimuth attitude of an antenna is within a specified range. CONSTITUTION:A yaw-angle-change-tracking control means (MPU) 4 turns and drives an antenna Ant through an azimuth mechanism 141 in the direction correcting the deviation of the attitude in elevation of the BS antenna Ant with respect to a radiowave source in correspondence with the attitude change detected with a yaw-angular-velocity detector 30. Thus, the attitude deviation of the antenna Ant with respect to the radiowave source by the directional change of a moving body is automatically corrected. The antenna Ant is turned and driven with a roll-angular-velocity detector 40 in the direction correcting the attitude deviation in elevation of the antenna Ant with respect to the radiowave source in response to the detected 40 attitude change, when the attitude of the antenna Ant in azimuth has an angle within a specified range with respect to the advancing direction of the moving body. Thus, the attitude deviation of the antenna Ant with respect to the radiowave source due to the rolling of the moving body is automatically corrected.

Title: Crime prevention reporting system
Inventor: HASE SHIGENARI
IPC: H04M11/04
Filed: 1993-12-28
Abstract: PURPOSE:To detect the occurrence of a fault despite the disconnection of a telephone circuit by outputting a monitor signal to a general subscriber telephone circuit from a monitor signal oscillator after the signal showing the disconnection of the telephone circuit is received from a disconnection detector means. CONSTITUTION:A control part 21 receives a disconnection signal from a disconnection detecting part 22 and outputs a stop signal to a monitor signal oscillator 5. Thus the monitor signal is never superposed on an incoming line 31 so that the occurrence of disconnection is reported to a center from the nearest switchboard. Under such conditions, however, it is impossible for the center to concretely and directly know the relevant situation. Then the center can indirectly know the situation since the occurrence of disconnection is reported from an exchange station.

Title: Testing system for lsi
Inventor: KATSUKI KENICHI
IPC: G01R31/28
Filed: 1992-12-16
Abstract: PURPOSE:To reduce number of operating test patterns of an LSI and a time to be consumed for testing one LSI by deleting number of the patterns to be used for a scan path test mode. CONSTITUTION:When a switching signal to a scan path test mode is input to an external input pin 1, F/Fs 11.1-11.n disconnect from combination circuits 8, 9, 10 to become one large shift register. A phase inverter 6 outputs an inversion signal of an input signal SCK of an external input pin 4 as an output signal SCKN of a clock phase inverter 6, and supplies it as a clock signal of the F/F via a signal line distribution line 7. In this case, when a test signal is input to an external input pin 2, the F/F 11.1 holds the test signal at a rise of the signal SCK and outputs it. Then, the F/F 11.2 holds the output signal of the F/F 11.1 at a rise of next signal SCKN, and outputs it. Thus, the test signal is shifted to the external output pin 3 at the rises of the signals SCK and SCKN.
