Abstract: PURPOSE:To obtain a film thickness measuring method which can measure the thickness of films with high accuracy even when the refractive index of the films are unknown, not to mention when the refractive index is known, and is the optimum for on-line measurement which must be completed at a high speed. CONSTITUTION:This film thickness measuring method which measures the thickness of films by irradiating a light transmissive film 3 having a known refractive index with electromagnetic waves measures the thickness of the film 3 in such a way that, after electromagnetic waves 1 having a single wavelength form an image on the surface of the film 3 through an image forming element 2, the formed image is again passed through an image forming element 4 and the image is taken by means of an image pickup element set to the focal point of the element 4. Then two positions where the signal intensity on the image pickup element becomes the extremal values due to the interference action of the electromagnetic waves in the film 3 are measured and the thickness of the film 3 is measured based on the information. When the refractive index of the film 3 is unknown, the thickness and refractive index of the film 3 are measured by measuring at least three positions where the signal intensity becomes the extremal values.

Title: Differential recording system
Inventor: WATABE KIYOSHI
IPC: G06F3/06
Filed: 1994-05-23
Abstract: PURPOSE:To enable the limitation of recording by preferentially reducing the recording amount at the time of a data restoration by not recording such data that can be regarded as equal to each other in the case of referring the log data. CONSTITUTION:When the data are supplied from a data generating source 1 in a data absence state and at a unit time, a log comparing part 31 assorts the data with an assorting key 42 and records an index, the recording record and the time to the log data 41 to be set in a log recording state. If new data is generated under such condition, the log comparing part 31 decides the presence or absence of the same assorting key and the differential data. If the presence of the same assorting key and the differential data 43 are confirmed, the part 31 decides whether the collected data reached its upper limit value. If the collected data are less than the upper limit value, the data 43 is recorded. Meanwhile, the final differential data is recorded in an idle area based on the next entry as long as the entry is confirmed for the differential data and the data 43 already exists. When the differential data reaches it upper limit of collection, only the disuse number of a disuse counter 44 is updated and the differential data is not recorded.

Title: Transistor device with current limiter
Inventor: ISHIKAWA HIROYUKI
IPC: G05F1/567
Filed: 1985-05-20
Abstract: PURPOSE:To maintain a value of an output current flowing through an output transistor, at a prescribed value irrespective of an ambient temperature, by forming a circuit by an output transistor, a current detecting resistor, a comparator, a reference voltage generating circuit, a control transistor, etc. CONSTITUTION:As a current flowing to an output transistor TR0 increases, a voltage drop in a detecting resistor R0 becomes large. Accordingly, a + terminal potential of a comparator 1 becomes higher than a - terminal potential, an output of the comparator 1 becomes a high potential, and a control transistor TR1 is turned on. Therefore, a conducting current is controlled to a prescribed value by decreasing a base current of the transistor TR0. Also, since a temperature characteristic of the resistor R0 and a reference voltage generating circuit 2 is very small, this prescribed current is maintained irrespective of an ambient temperature.
