Title: Solvent spectrum erasing type spectrophotometer
Inventor: FUKUDA JIYUNICHI
IPC: G01J3/42
Filed: 1979-01-24
Abstract: PURPOSE:To obtain a spectrophotometer which permits conducting an analysis operation at a very high effieiency, by memorizing spectra of various kinds of solvents in a memory element, such as a casette tape in the spectrophotometer, and subjecting a spectrum from a cell on the sample side and the corresponding spectrum in the memory element to operation. CONSTITUTION:A solvent and sample are placed in a cell on the signal sample side 2. A cell on the reference sample side 3 is left as it is. Light is applied from a light source 1 to send a spectral output to a data processing unit 5. A spectrum which is included in the spectra of various kinds of solvents memorized beforehand in a memory element 6 and which corresponds to the solvent actually used is extracted, and both of the spectra are subjected to operation to be erased. Thus, a spectrum of the sample alone is obtained. This allows a troublesome operation for preparing a solvent to be omitted, so that the analysis of a sample can be carried out at a very high efficiency. Since a casette tape is used to memorize the spectra of solvents, it is possible to preserve semipermanently the spectra of solvents as specimens.

Title: Intake air flow detector of internal combustion engine
Inventor: TOMIZAWA NAOMI
IPC: G01F1/698
Filed: 1992-01-17
Abstract: PURPOSE:To ensure the detection response until a temp.-sensitive resistor becomes the vicinity of usual control temp. and to control fuel well in response to a change in intake air flow by correcting response delay on the basis of the characteristics corresponding to the elapse time after the power supply of a temp.-sensitive flowmeter is turned ON. CONSTITUTION:The output voltage Us of a temp.-sensitive flowmeter 1 is inputted to a microcomputer 4 through an A/D converter 3. The microcomputer 4 has an elapse time measuring means, a change quantity operation means, a coefficient variable setting means, an intake air flow correction output means or the like. The change quantity per a predetermined time of the detection value of the flowmeter 1 is operated and the value obtained by multiplying said change quantity by a predetermined coefficient is added to a this-time detection value to obtain a final detection value. Therefore, the value obtained by amplifying the detection value when the detection value changes is set to the final detection value to make it possible to correct the response delay of the detection value. Moreover, by variably setting the predetermined coefficient corresponding to the elapse time after the power supply of the flowmeter 1 is turned ON, response delay can be corrected on the basis of the characteristics corresponding to response characteristics changing with the elapse of time.

IPC: G06F11/00
Filed: 1979-01-26
Abstract: PURPOSE: To ensure the diagnosis up to the final step of the digital circuit with diagnosis by extracting the feedback signal out of the driver circuit.  
     CONSTITUTION: Each digital input signal 2, featuring H, is latched to each FF circuit 5 by timing signal 1, and the output signal 11 becomes H. Thus each transistor 8 is turned on, and each process signal 15 becomes L along with each load 9 functioning. At the same time, each diode 14 is turned on, and each signal 17 becomes L. And each feedback output signal 3 of driver circuit 16 becomes H via timing signal 4. Now in case transistor 8-1 has some fault and thus can not be turned on, process signal 15-1 becomes H along with diode 14-1 turned off and signal 17-1 changed to H each. And thus feedback output signal 3-1 becomes L to inform the circuit fault to the computer. Thus the diagnosis can be given up to the final step of the circuit.

Filed: 1993-01-20
Abstract: PURPOSE:To accomplish highly precise superposition by a method wherein the amount of rotational deviation computed by an automatic compensation system, with which relative positional deviation between a reticle and a wafer is measured by the projected image of the reticle using an exposing light, is corrected by rotating the reticle. CONSTITUTION:The amount of deviation of relative rotation of a reticle 2 and a wafer state 8 is measured by an automatic compensation system which recognizes the position of the reticle 2 by the reticle image which passed through a reduction lense 7 using the exposure optical system of a reduced projection- exposure device. The amount of rotational deviation, which is computed by the above-mentioned automatic compensation system, is reflected to the reticle 2 by rotating a reticle stage 6. Consequently, as the correction of rotation by wafer is unnecessitated and reduced by the reduction lense, a highly precise positioning can be conducted.
