Title: Circuit simulation method
Inventor: NAKANO TADASHI
IPC: G06F17/50
Filed: 1995-05-12
Abstract: PURPOSE: To prevent a divergent phenomenon at a circuit with a large amount of MOS capacity by using a half, or the average, of the sum of a last-time capacity value and a this-time capacity value under iteration at the same time as the this-time capacitor value as the capacity value of a voltage dependency capacity. CONSTITUTION: The this-time capacity GGGS of iteration is obtained first. A substrate source voltage VBS sets only positive MOSFETs to be objects. If all MOSFETs converged already are set to be the objects, convergence is delayed so that only MOSFETs whose substrate source voltage is a forward bias are set to be the object. At the time of the first time point of transient analysis and the first iteration of the time point of transient analysis, this-time capacity is made to be the last-time capacity. At the time of excepting for it, the last time capacity under iteration is taken out to GGGS1. Then the half, or the average, of the sum of the this-time capacity and the last-time capacity is used as the this-time capacity. The final this-time capacity is set to be the last-time capacity.

Title: Electric fuel injection pump governor
Inventor: OGISO HARUHIKO
IPC: F02D41/08
Filed: 1983-06-24
Abstract: PURPOSE:To keep the idle engine speed constant by calculating the directed fuel injection quantity adjusting member position based on the internal value obtained from the input value when the accelerator opening is not zero and updating it based on the engine speed deviation between the target and actual engine speeds when the accelerator opening is zero. CONSTITUTION:The input value alpha1 is the accelerator operation quantity inputted from the signal of an accelerator position sensor 122, the internal value alpha2 is the virtual accelerator operation quantity determined by alpha2=(100-KalphaL)X alpha1/100+KalphaL, and the target injection quantity is determined based on it and the engine speed. this governor pattern is the value of alpha2 when alpha1 equals 0%, and alpha2 is 100% when alpha1 equals 100%. Next, when an engine is in an idle condition and the actual engine speed and target engine speed differ, the internal value alpha2 is increased or decreased to make the actual engine speed near the target engine speed. Here, the target engine speed is determined by the signal from an idle regulator 126. Thereby, the idle engine speed can be kept constant.

By driving the embroidery frame to negative direction of the X axis, the mobile lever is attached to the back of the embroidery frame and the position of the back of the embroidery frame is detected. Thus detected position of the front part of the embroidery frame and the position of the back of the embroidery frame are stored in a RAM. Further, the size of the embroidery frame can be obtained by the arithmetic operation based on the positions and the type of the embroidery frame is automatically discriminated (S6). Then, whether the embroidery frame is proper to the sewing of the selected embroidery pattern is checked (S7).

IPC: H01L21/302
Filed: 1988-05-13
Abstract: PURPOSE:To enable the exact detection of an end point of resist decomposition reaction, by a method wherein, when organic material on the surface of an object to be treated is decomposed and eliminated, ultraviolet rays whose wavelength is absorbed by the organic material, and not absorbed by oxygen/ozone mixed gas is projected on the surface of the object to be treated, and the reflected light is detected. CONSTITUTION:A wafer 4, wherein processes of resist coating, exposure, development and etching are finished, is horizontally mounted on the upper surface of a wafer mounting stand 3 heated at a specified temperature. Then, the wafer mounting stand 3 is rotated at a specified speed; oxygen/ozone mixed gas is supplied to the inside of a chamber 2, from the tip of a gas feeding pipe 6; the gas is sprayed against the central part of the wafer 4. Excited oxygen molecule is generated by ultraviolet rays radiated from a low pressure mercury lamp 8: this active molecule is uniformly diffused on the wafer 4 surface, and decomposition reaction of resist is started. While the resist decomposition reaction of the wafer 4 surface progresses, the ultraviolet rays radiated from the low pressure mercury lamp 8, whose wavelength is 313nm (or 365nm), are absorbed by the resist. As a result, whether there is resist on the surface of the wafer 4 can be accurately discerned, by detecting the reflected light intensity by a photo detecting means 10.

IPC: B41J13/00
Filed: 1988-05-13
Abstract: PURPOSE:To avoid a printer from stopping as much as possible and to improve an operation rate by permitting arranged sensors to decide abnormal printing because a sheet is carried at an inappropriate timing. CONSTITUTION:The sheet 2 is picked up from a sheet tray 1 by means of a pickup roll 3, sent to resist rolls 4 and 4' through the sensor 5, passed by the transfer device 10 of a printing part, fixed in a fixing device 13, and sent to an eject tray 16. At that time, the sensor 20 checks the way that the sheet 2 is carried through the resist rolls 4 and 4', and transmits various instructions. When the sheet is detected by the sensor after a prescribed length of time has passed, it is regarded as a case where the sheet is sent at an inappropriate timing, and the sheet is discharged, and simultaneously a signal instructing to pick up a next sheet is outputted. Thus, the stoppage of a printer is not needed to significantly improve the operation rate.
