Title: Event qualification test architecture of integrated circuit
Inventor: RII DEII UIITSUERU
IPC: G06F11/267
Filed: 1990-02-08
Abstract: PURPOSE: To execute a boundary test in an operation mode of an IC, by storing and logically operating arriving data by a logic circuit connected between an input and an output circuits of the IC, and comparing the data with estimation data. CONSTITUTION: Arriving data are stored, logically operated, etc., by a logic circuit connected between a data input D0-7 and a data output Q0-7 of an IC. The data are analyzed and stored by an input and an output test registers(TCR) 12, 22 when a predetermined state is detected. At this time, the predetermined state can be detected by comparing data from the logic circuit with a stored estimation data word. On the occasion of a boundary test, test data are shifted into a test circuit of the TCR 22 under the control from a test port 48. An event recognition module 30 generates a control in accordance with an input of the predetermined state via a CTERM signal, and outputs a test pattern to the output Q0-7. Accordingly, data passing a boundary of the IC can be dynamically observed.

Abstract: PURPOSE:To elevate bonding strength, and to prevent the increase of the thermal resistance of a joining layer by laminating a solder material for joining containing an active metal for joining with a ceramic board to one of the surfaces of a metallic plate for a circuit board. CONSTITUTION:In a metallic plate 20 for circuit board, a solder material 22 for joining including an active metal is laminated onto the whole surface of a metallic plate 21. It is favorable that the solder material 22 is laminated only onto one surface of the metallic plate 21, but the solder materials 22 may be laminated onto both surfaces. Thickness required for firmly cementing the metallic plate 1 and a ceramic board 1 is sufficient as the laminating thickness of the solder material 22 for joining, and the laminating thickness is not limited particularly, but approximately 3-100mum is enough. 5-50mum is more preferable. The quantity of the solder material 22 is insufficient and the metallic plate 21 and the ceramic board 1 cannot be joined sufficiently when the thickness is less than 3mum, and the solder material 22 is too much as thermal resistance is increased with the increase of thickness when the thickness exceeds 100mum.

Title: Mosfet switch circuit
Inventor: MASUDA EIJI
IPC: H03K17/16
Filed: 1982-02-25
Abstract: PURPOSE:To reduce the on-resistance and an offset voltage, by connecting a plurality of MOSFET switches in parallel and turning off them with a plurality of delay circuits at turn-off. CONSTITUTION:The sum of channel widths of FETs constituting a plurality of MOSFET switches is taken for one FET. When a signal -phi given to an inverter 5 is ''H'' level, signals -phi1--phi4 are stable at the ''H'' level and the FETs of switches 21-24 are set on. When the signal -phi goes to ''L'' level, the signals -phi1--phi4 are sequentially delayed with resistors 25-32 and given to the FETs. Even if an offset voltage is generated with the switch 21 to be set off, when the switches 22-24 are still set on, the offset voltage is cancelled immediately. The offset voltage generated at the switches 21-23 is sequentially cancelled. Thus, the offset voltage generated in the switch 24 is made sufficiently small.
