Filed: 1983-08-29
Abstract: PURPOSE:To absorb a difference in belt tension due to a difference in length between the belts, by a method wherein a pinch roller is formed integrally with a tension roller, and the rollers are energized with each other through the force of a spring to allow independent application of tension on each belt. CONSTITUTION:In a roller constitution body 6 mounted to each belt 2, by installing a compression spring 14, an arm 10 is energized such that it presses a pinch roller 8 against a belt 2 on a support roller 3. An arm 11 is also energized so that it presses a tension roller 9 against the belt 2. As a result, the pinch roller 8 presses the belt 2 against the roller 3 to achieve the function of the pinch roller, and the further movement is stopped by the roller 3. Meanwhile, the tension roller 9 presses the belt 2 to apply tension, proportioning the force of the spring 14, on the belt 2. This enables absorption of the tension of the belt 2 due to a difference in length between the belts 2.

Title: Method and device for measurement and machining
Inventor: HOSOI KEIICHI
IPC: G01B11/00
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To avoid reduction in accuracy, caused by vibration with the uniformity of measuring and machining atmosphere, being secured by suppressing the generation of the vibration by decreasing the air-blowing capability of an air blower, immediately before the measurement after enhancing the uniformity of the measuring atmosphere by the air blower. SOLUTION: Laser light 11A, emitted from a laser source 11, is condensed on a sample 1 by an objective lens 13. The reflected and scattered light is received by a photodetector 14. When a measuring point crosses patterns 1A, 1B and 1C, the intensity of the detected light of the photodetector is changed at the position of the edges of theses patterns. The coordinates of the edges of the patterns 1A, 1B and 1C can be measured as the position of a stage 2 at that time, from the measured data of an interferometer 5, when the intensity of the detected light changes. When the measuring points are separated from the patterns 1A, 1B and 1C and the ambient temperature is higher than a target temperature, an air blower 201 is rotated at high speed, so as to approach the target temperature.  When the measuring point approaches by a constant distance, the air blower is switched to the low-speed rotation, and the coordinate measurement of the edge is performed, after the number of rotation has sufficiently lowered.

Title: Fuel control device for engine
Inventor: CHIKAMORI TAKESHI
IPC: F02D41/14
Filed: 1991-06-28
Abstract: PURPOSE:To control a fuel injection amount by the desired air-fuel ratio over a total load region even in the case that an opening/closing point displacement amount of the second intake passage relating to the first intake passage is displaced from a preset value, in the case of a fuel control device by which the fuel injection amount in an engine, closing the second intake passage of a pair of the intake passages by a load of predetermined value or less, is controlled by using an intake pipe pressure detection value of the first intake passage. CONSTITUTION:A study correction value is calculated based on a difference between a detection value 44 of air-fuel ratio A/F, when fuel injection amount control 12 is performed in a region as shown by meshes, and an air-fuel ratio feedback target value. This calculated study correction value is reflected only to fuel injection amount control in a load region of opening the second intake passage 24S. Thus in a load region (load region of closing the second intake passage) with no influence by an opening/closing point displacement amount, the study correction amount is prevented from being reflected to prevent a bad effect where the fuel injection amount control can not be performed by the desired air-fuel ratio.

IPC: G01R31/26
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To collectively measure each gate length of all MOSFET device, where a design gate length on a reticle differs by measuring the channel resistance of the MOSFET devices and then measuring the gate length of the devices. SOLUTION: A channel resistance for each gate length is obtained for a plurality of MOSFET devices with a different gate length on a reticle with respect to each specific gate device, and a straight line that has been approximated to each specific gate device is obtained from the characteristics of an actually measured value (S1). The actually measured value of the channel resistance of the MOSFET device of a gate length on a specific reticle is obtained for each specific gate bias (S3 and S4), and a gate length is corrected (S5) so that the actually measured value approaches a straight line that is linearly approximately with respect to all the previous gate biases.  Further, the actually measured value of a channel resistance are obtained for all of a plurality of MOSFET devices with different gate lengths on the reticle for each specific gate device and a gate length is corrected, thus collectively measuring the gate length of the plurality of MOSFET devices with differing gate lengths.

Title: Drum winding/tightening controller
Inventor: HASHIMOTO JUNYA
IPC: B21C47/30
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent a drum from being damaged by installing a means to predict the coefficient of friction between a drum and a strip, a means to detect the tension of the strip, a means to calculate the internal pressure of the drum, a means to set the upper limit value of the internal pressure of the drum, an internal-pressure comparing means to output the speed correction amount of the drum, and a means to control drum speed, and by operating various controlled variables before the internal pressure of the drum becomes too high. SOLUTION: The means to predict the coefficient of friction predicts through an inverse operation, the coefficient μ of friction between a drum and a strip by relating it to the rolling load. A tension detecting means converts a tension t outputted from a tension gauge to a digital signal T. The predicted value of the coefficient μ of friction and the tension T are added to an internal-pressure calculating means and converted to a shearing force τ for each winding unit. The means to set the upper limit value of internal pressure sets an upper limit value P' in consideration of the mechanical allowable stress, and the internal-pressure comparing means outputs a speed correction volume to the speed controlling means if the internal pressure P>=P'.  From the relationship of P=τ(T)/μ, if the tension T decreases due to speed increase, the shearing force τ decrease and the internal pressure P also decreases.

Title: Delay circuit
Inventor: OBATA HIROYUKI
IPC: H03K5/13
Filed: 1989-06-20
Abstract: PURPOSE:To configure a delay circuit in which no delay time is fluctuated even when the characteristic (absolute accuracy) of a MOS-FET is fluctuated by deciding the accuracy of the delay time essentially only with the accuracy of a capacitance value and a resistance value. CONSTITUTION:The circuit is comprised of first, second, fourth, and sixth MOSFETs (P1, P2, P4, and P6) of P-channel type, third, fifth, and seventh MOSFETs (N3, N5, and N7) of N-channel type, first and second resistor terminals (R1 and R2), the capacitance element (C), and an inverter. The delay time tD of the delay circuit can be given by equation I, and the delay time tD can be set by setting the capacitance value, the resistance value, and the gm ratio of the MOSFETs P2 and P4. Here, when MOS integrated circuits formed on the same substrate are used, the gm ratio (relative accuracy) of the same conduction type MOSFETs can be set with very high accuracy. Thereby, the delay time can be prevented from fluctuation at all even when the characteristic of the MOS-FET comprising the delay circuit is fluctuated.
