Patent JP-H06303131-A (JP)
Title: Pll circuit
Inventor: ASAHI KOJI
IPC: H03L7/087
Filed: 1993-04-15
Abstract: PURPOSE:To satisfy a broad capture range, a narrow band and a low steady- state phase deviation simultaneously in the PLL circuit by providing two loops having a high phase comparison frequency and a low phase comparison frequency and selecting the response speed of the loop whose phase comparison frequency is low to be higher than that of the loop whose phase comparison frequency is high. CONSTITUTION:A phase comparator 2 detects a phase difference between an input clock and a clock resulting from frequency-dividing an output clock at a 1/N frequency divider circuit 7 in a loop I. On the other hand, a phase comparator 10 detects a phase difference between an input clock subjected to 1/M frequency division and a clock resulting from NXM frequency-dividing an output clock in a loop II. Then the detected differences are added via LPFs 3,11 and the sum is fed to a VCO 5 to apply frequency control to the output clock. The loop II is dominant when the PLL is in the transient state by setting the response speed of the loop II sufficiently higher than that of the loop I, the capture range is set wider and a narrower band is attained. On the other hand, in the steady-state, the loop I is dominant and a steady-state phase deviation is reduced.

Title: Modeling method for field effect transistor
Inventor: SAITO TOSHIYUKI
IPC: G06F17/50
Filed: 1987-05-06
Abstract: PURPOSE:To decrease a calculation cost and also improve modeling in accuracy by a method wherein the property of a field effect transistor is modeled through a numerical table formed at each intersection of bias meshes of a gate, a bulk, and a drain. CONSTITUTION:The bias dependency of the property of a given field effect transistor is obtained through sampling of internal information of the device and the meshes of a bias voltage is so set as to be fine in the region where the property changes rapidly and coarse in the region where the property changes slowly. Therefore, the meshes of the bias voltage can be determined depending not on the size of a field effect transistor but on a generalized manner and a few bias mesh intersections can represent the property of a field effect transistor very accurately, and thus, for example, modeling of the property can be accomplished with better accuracy through the bias mesh intersections less than 1/3 those required in a conventional manner. By these processes, the calculation cost of the device simulation needed for the formation of a table model can be remarkably reduced.

Title: Temperature detector
Inventor: WATANABE YOSHIHARU
IPC: G01D7/00
Filed: 1979-08-31
Abstract: PURPOSE:To enlarge the measured temperature range by expanding changes in the magnitude of mechanical energy generated with an electromagnetic mechanism through an injection pressure of pressure gas. CONSTITUTION:A change in the temperature of a test material 1 generates electromotive force of a thermocouple 2 to provide current to a coil 6, which then rotates solidly with an arm 8 and a center shaft 7 through the electromagnetic effect with a permanent magnet 5 while an injection pressure receiving member 13 turns solidly. This varies a clearance between a nozzle 12 and the injection pressure receiving member 13 to break the balance between the injection pressure of the pressure gas and a spring 19 pressing the nozzle 12 so that the nozzle 12 displaces in such a direction that the clearance with the injection pressure receiving member 13 is kept constant. At this point, the injection pressure of the pressure gas injected from the nozzle 12 expands the change in the force turning the coil 6 by an electromagnetic mechanism 4, which is extracted as displacement of the nozzle 12. The displacement of the nozzle 12 is transmitted to a lever 25 of an expansion device 24 to swing a pointer 27, whereby the detected temperature is displayed.
