摘要： PURPOSE:To know the coverage of a program to be measured by loading an object program in a control mode and carrying it out in a carry-out mode to set the control mode again after execution of the program and reading all addresses stored in the object program. CONSTITUTION:When the coverage of a program is measured, a control mode line 12 is set at 1 (control mode) and the program to be measured for its coverage is loaded. Then 0 is loaded into an additional bit memory part 1 and the program to be measured is loaded into the data bit memory parts 2-0-2-7 respectively. In this case, the control mode is released and a program carry-out mode is set (the line 12 set at 0). Thus the program to be measured is carried out and 1 is written into the part 1 corresponding to the relevant access address every time an access is given to a memory. When the execution is through with the program to be measured, the control mode is set again and a storing area for the program to be measured is read out. Thus the contents of the part 1 can be read out to the 0-th bit of data. Based on said contents, it is possible to know whether the relevant address received an access or not.

摘要： PURPOSE:To quickly detect the faulty areas by storing the fault information obtained in a working state prior to the separation of a system from a duplex system and executing a prescribed diagnosis program for the separated system via a service processor to edit and output the result of said diagnosis when the abnormality is detected. CONSTITUTION:The fault information obtained in a working state is stored before a faulty system is separated from a duplex system and a service processor started with occurrence of a fault carries out a prescribed diagnosis program to the system separated from the duplex system. When a fault is detected, the result of said diagnosis is edited and outputted. While the stored fault information is analyzed and the result of this analysis is edited and outputted when no fault is detected. Thus the general faults excluding the intermittent faults, etc., can be detected quickly and accurately with conventional execution of the diagnosis program. In addition, the areas of special faults like the intermittent faults, etc., are estimated based on the result of analysis of the stored information.

摘要： PURPOSE:To readily achieve probing of lower layer wirings in a semiconductor integrated circuit having a multilayer interconnection structure by forming a dummy through hole having no electric connection with upper layer wirings on the lower layer wirings. CONSTITUTION:Lower layer wirings 1, 4 are formed through a field insulating film 6 on a semiconductor substrate 9, and upper layer wirings 2 are further formed through an interlayer insulating film 7 thereon. The wirings 2 and 1 are electrically connected through a contacting through hole 3. A dummy through hole 5 which is not electrically connected with the wirings 2 is formed on the wirings 4 to be exposed. The entire surface is covered with a protecting film 8. Since the wirings 4 are exposed through the hole 5, a charge by the film 7 is not generated even by a probing under a scan type electron microscope.

摘要： PURPOSE:To eliminate waveform distortion of the output after an analog low- pass filter and to mold a frequency spectrum in the desired band by latching the logical gate output once, executing the outputting through an inverter, and making constant the time width of respective pulses of the aperture output sent to an aperture correcting circuit. CONSTITUTION:In an aperture output generating circuit 5, a signal D and a clock phi are inputted into a NAND gate 6, and an output 6a is inputted into a latch circuit 7. In a latch circuit 7, by a clock phi1 and an inverting clock phi', the data are latched and outputted. Thus, when the data are latched once, the constant value is latched even when a signal 6a fluctuates with time, and since the data are outputted as an inverter, the signal of the constant pulse width can be obtained as an aperture output Q1.

摘要： PROBLEM TO BE SOLVED: To perform file updating without stops, even in a processing system for performing an on-line service for which continuous services are required. SOLUTION: At storing of a new file in a first or second application software part 3 or 5, according to the sweeping processing instruction of service of APL, a service is temporarily degenerated on an APL degeneration software 8 of a basic software part 2. At finishing of the sweep of service of the APL, processing is moved to the first or second application software part 3 or 5, where the new file is stored. Whereas at updating of the file of a basic software, the service is degenerated and executed by pseudo basic software parts 4 and 6 of the first and second application software parts 3 and 5 and the APL and after the file is updated, processing is returned from the pseudo basic software parts 4 and 6 to the basic software part 2.

摘要： PURPOSE:To measure with high accuracy a frictional characteristic between a semiconductor sealing material and a packing material by measuring simultaneously an electrification state of a rubbing object and an object to be rubbed and a momentary variation of the electrification of each of them, with regard to an electrification characteristic which follows up a friction. CONSTITUTION:An object to be rubbed 1 being an object to be measured is installed on a moving stage 6. A rubbing object 2 is attached to an insulating supporting body 4 provided with a frictional pressure adjusting weight 5. Weight of the weight 5 is allowed to work on the rubbing object 2 and it is placed on the object to be rubbed 1. On the surface of the rubbing object 2 and the object to be rubbed 1, surface potential sensors 3a, 4b are provided, and when the moving state 6 is moved in the right and the left directions as indicated with an arrow, a friction is generated on the interface of the rubbing object 2 and the object to be rubbed 1, therefore, each electrification characteristic is measured simultaneously by said surface sensors 3a, 3b. As for the rubbing object 2, a thin sheet-like object is used.

摘要： PURPOSE:To prevent an IC incorporated in an IC card from being damaged, by constituting the carrying-in and the carrying-out openings of the IC card of an insulating material, constituting and grounding a card carrying mechanism of a conductive material, and furthermore, providing a mechanism which performs the static elimination of the surface of the card. CONSTITUTION:The IC card 9 inserted from a card insertion opening 1 is carried to an IC card reading part 8 by card carrying loaders 4, 5, and 6 and auxiliary loaders 7a and 7b, and is carried further to the carrying-out opening 2 of the card. In such a case, the card insertion opening 1 is constituted of the insulating material, and the static elimination at the time of inserting the IC card can be prevented from being generated. Also, since the feeding mechanisms 4, 5, 6, 7a, and 7b of the card are constituted of conductive components and connected, the triboelectrification of the card 9 can be reduced. Furthermore, static eliminating brushes 10 and 11 are provided on the upper and lower sides of the carrying path of the IC card 9, thereby, the static elimination of the IC card is performed. Also, since the carrying-out opening 2 of the card is constituted of conductive plastic, the electrification of the card 9 can be prevented from being generated.

摘要： PURPOSE:To prevent local deviation of electric charge and to prevent a high potential at a local plate, by forming a highly resistive printed resistor film on the entire surface of a substrate except for electrodes and an integrated- circuit-chip attaching part of the substrate, thereby uniformly distributing the electric charge on the entire surface of the integrated-circuit mounting substrate and an IC. CONSTITUTION:A COB is formed as follows. An integrated-circuit chip 2 is mounted on an insulating substrate 1. Electrodes 3 are taken out of the integrated circuit chip and arranged on the insulating substrate. A highly-resistive printed resistor film 7 is formed on the entire surface except for an integrated- circuit-chip attaching part and the electrode on the substrate. Thus, the highly resistive (about 1MOMEGA/square) printed resistor is applied on the entire surface of the COB. Therefore the substrate of the COB and the IC become the almost equal potential.
