Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a flowmeter which can make high speed and high accuracy measurement. SOLUTION: A frequency measuring part 21 measures frequency of a pulse signal corresponding to a flow rate from a sensor 11, and an instantaneous flow rate calculation part 22 and an integration flow rate calculation part 23 calculate an instantaneous flow rate and an integration flow rate based on the frequency. In addition, a prediction calculation part 25 calculates a predicted integration flow rate at next measurement timing, and when the predicted integration flow rate exceeds a set integration flow rate value, a measurement cycle of the frequency measuring part 21 is shortened. Thus when the integration flow rate reaches the set integration flow rate value which has been preset, an integration batch operation terminate signal is output to a centralized monitor device EXCT without delay.

Abstract: PURPOSE:To prevent erroneous alignment caused by difference in quality or reflectance of films on a wafer, by controlling a gain of an alignment signal in every fine region with reference to zero-th order diffracted light of laser reflected from the wafer. CONSTITUTION:A laser beam is applied to a lattice alignment mark on a semiconductor substrate 4 so that positional detection is performed by means of diffracted light therefrom. For that purpose, a diffracted light separating plate 5 is provided for separating it into a plurality of diffracted lights including zero-th order diffracted light. Respective intensities of the separated lights are detected by a plurality of detectors 7. With reference to the intensity of the zero-th order diffracted light thus obtained, gains of alignment output signals dependent on intensities of the other diffracted lights are adjusted. In this manner, it is made possible to eliminate erroneous alignment or need of correction by an operator that is caused if adjustment fails to correspond to alignment signals which vary greatly in accordance with qualities of the films on the wafer.

IPC: G06F9/45
Filed: 1990-10-05
Abstract: PURPOSE:To accurately find the value of the constant of rearranging addresses that require operation at the time of linkage edition by outputting the kind of operation and value of an operand to a rearrangement table. CONSTITUTION:A translation processing program 5 generates an object module 6 by translating a source program 4 and the kind of operation and value of an operand are contained in addition to control information, such as rearrangeable addresses, etc., required for rearrangement on a rearrangement table 7 which is generated and outputted when the module 6 is generated. A linkage edition program 8 links object modules A and B to each other and converts the values of the rearrangeable addresses in accordance with the table 7. At the time of the conversion, operation is executed on those that require operation of the rearrangeable addresses. For example, an address constant LABEL 1/16 is operated in the form of (LABEL1+X'B00')/16 and replaced with the value obtained as the result of the operation. Therefore, the value of the constant of rearranging addresses that require operation can be found accurately at the time of linkage edition.

Title: Self-diagnosing pyroelectric detector
Inventor: SOTANI TOSHIYUKI
IPC: G01J1/02
Filed: 1992-09-09
Abstract: PURPOSE:To enable self diagnosis with a weak current and require approximate zero wait time after the diagnosis by adhering a pair of electrodes to the face of a pyroelectric material, adhering a common electrode to the other face, and forming an additional resistor in the vicinity of grounding terminal of one of the pair of the electrodes. CONSTITUTION:Light receiving electrodes 2, 3 adhered to the surface of a pyroelectric material 1 have a shape and a light receiving area equal to each other where light reception sensitivity is equal, while an additional resistor R is integrally formed in the vicinity 2a of a grounding terminal of one of the electrodes 2. On the other hand, a common reflecting electrode is adhered to the back of the material 1. Since the light reception sensitivity is equal in the electrodes 2, 3, common mode noise such as sunlight or lighting is offset, and if there is an invader, difference in temperature occurs between the surface and the rear face of the material 1 to have a detection signal output. At the time of self diagnosis, weak current for checking is applied to heat the electrode 2 by the resistor R to raise its temperature so that difference in temperature is caused from an electrode 4, thereby, checking detection sensitivity by detecting pyroelectric current caused by the difference.

Filed: 1988-10-25
Abstract: PURPOSE:To prevent the jamming of paper by erroneous operation by issuing an alarm when a comparing means detects the change of a paper selection and detection means when a paper detection means detects the presence of paper. CONSTITUTION:When the power supply of a printing apparatus is turned ON, the state of a paper selection means 2 is stored as an initial value. Next, the state of paper is detected by a paper detection means 1. In the case of no paper, the state of the paper is detected until reaching a paper presence state and, when the paper presence state is detected, the state of the paper selection means at the present point of time is stored as a value for comparison due to a comparing means 5. In the case of the presence of the paper, the state of the paper selection means at the present point of time is compared with the stored state of the paper selection means by a comparing means. In the case of the presence of the paper (wherein no change is confirmed in the state of the paper selection means), nothing is said and, in the case of no paper, an alarm is emitted to again return to a paper detection processing. So far as the power supply of the printing apparatus is turned ON, an alarm is issued according to procedure and the jamming of the paper due to erroneous use can be prevented.
