Patent EP-0274613-A1 (EP)
Inventor: BOYLE DAVID H
IPC: H01L29/78
Filed: 1987-11-17
Abstract: The performance predicting circuit is embodied on the same integrated circuit chip as are the integrated circuits whose signal propagation characteristics are to be measured. The circuit has an input node 40 to which is applied a tester driver frequency which is characteristically approximately a 3 MHz square wave. A series connected array of three FET load devices, Q10, Q11 and Q12 are connected between the input node 40 and the node 42. Each FET load device Q10, Q11 and Q12 has the same dimensions as the FET load devices in the circuits to be characterized on the integrated circuit chip. In that manner, variations in the degree of etching of the polycrystalline silicon gates and variations in the diffusion temperature for the source and drain of the FET load devices will equally affect the characteristic impedance of the FET load devices Q10, Q11, Q12 and the circuit devices. Variations in the gate oxide thickness which occur during the manufacture of a given integrated circuit chip will also influence the effective transconductance of the FET load devices and will be reflected in the behavior of the devices Q10, Q11 and Q12 of the performance predicting circuit. 
     Connected to the node 42 are three capacitive equiva­lent circuits CʹM2, CʹM1 and CʹGX. The capacitive equivalent circuit CʹM2 consists of a depletion mode FET device Q13 which has the same characteristics as the devices Q10, Q11 and Q12. CʹM2 also includes the enhancement mode active device Q14 which is connected through the feedback capacitor CM2F. The capacitor   CM2F has a structure which characterizes the capaci­tance CM2 of second level metal conduction lines. 
     The capacitive equivalent circuit CʹM1 includes a depletion mode load device Q15 which is the same as the device Q10 and an enhancement mode active device Q16 which is connected to the feedback capacitor CM1F. The capacitor CM1F is made up of a serpentine array of M1 conductor line whose capacitance with respect to the substrate 20 characterizes the capacitance for unit length of conductor lines on the M1 level. 
     The capacitive equivalent circuit CʹGX also includes a depletion mode FET load device Q17 which is the same as the device Q10. It includes an enhancement mode active device Q18 which is connected through an MOS capacitor Q19. The MOS capacitor Q19, provides a thin oxide capacitance whose magnitude characterizes the thin oxide capacitance CGX for the polycrystalline silicon gate capacitance with respect to the semicon­ductor substrate.

Abstract: Apparatus and method for generating thermal and electrical energy, in which thermal energy is derived from an internal combustion engine (12) by a flow of coolant and electrical energy is derived from an A.C. generator (14) driven by the engine (12). Outputs required of the apparatus are determined automatically by a control system (50) which monitors the required loads and then adjusts the relative outputs of the engine (12) and generator (14) to optimal levels. Engine speed is variable without affecting the generator output frequency because of e.g. an epicyclic gear train (42) between engine (12) and generator (14). The apparatus may be used in combination with external energy sources, monitoring these and adjusting its own outputs according to efficiency; on a substantial drop in electric power from the external source the system may by automatic override cause maximum output from the electrical generator (14) regardless of the thermal load.

Abstract: A printhead is formed by injecting unfilled nylon by injection unit 1 and mineral filled nylon by injection unit 3. The filling adds impact resistance for printing, while the unfilled nylon is particularly resistant to flexural fatigue near the hub of the printwheel. 
     Unit 1 is operated first to form an outer layer, with quantity limited so that the outer layer comes to about the middle of the arms of printheads. Unit 2 is then operated to form a core and to be the only material forming the character elements. 
     The resulting printhead is durable and is capable of use at greater deflection than the same printhead made of only the impact resistant material.

Abstract: This invention relates to a microwave incinerator for incinerating organic matter having a high water content, such as garbage. by using microwaves This incinerator consists of a primary combustion chamber (4) in which garbage, an object to be incinerated. is placed, and a secondary combustion chamber (18) in which a gas of the decomposed garbage (2) is burnt. In the chamber (4). the garbage (2) is decomposed or carbonized by microwaves and, in the chamber (18) in which microwaves are not radiated, the decomposition gas is burnt by an igniter. The incinerator of the above-described construction has the following characteristics. The garbage is dried by microwaves into a high-quality fuel, which is then decomposed and completely burnt. Accordingly, the waste gas from the incinerator is clean. Since the garbage can be reduced into ashes completely at a high temperature, the incineration of the garbage can be carried out sanitarily. This invention relates to a structure, a control method and a material required for a novel microwave incinerator. These essential elements enable the above-described operations.
