Title: Reflectivity measuring apparatus
Inventor: KOIKE MASAHITO
IPC: G01N21/55
Filed: 1987-05-29
Abstract: PURPOSE:To measure the reflectivity of a mirror surface caused by the vertical input of light directly, by using 1/4 wavelength plates, crossing the linearly polarized light at the incident side and the linearly polarized light on the reflecting side at a right angle, and making it possible to split the incident light and the reflected light. CONSTITUTION:Luminous flux from a light source is made to pass through a polarizer 3. The luminous flux is split into two luminous fluxes through a polarized light beam splitter 4. One luminous flux is made to pass through a 1/4 wavelength plate 5 and inputted into a sample Ms. The other is made to pass through a 1/4 wavelength plate 6 and inputted into a reference mirror Mr. The reflected light beams from the sample Ms and the reference mirror Mr are inputted into a photodetector D through the 1/4 wavelength plates 5 and 6. At this time, the incident light and the reflected light are converted into the linearly polarized lights, whose polarizing directions are crossed at a right angle each other. Therefore, the incident light and the reflected light can be readily separated. The detected signals based on the reflected light from the sample Ms and the reflected light from the reference mirror Mr are separated in a sampling circuit Sw, which is synchronized with the rotation of the polarizer 3. A control circuit C computes a relative reflectivity based on said detected signals.

Abstract: PURPOSE: To accurately measure an extension due to the urea of a link chain in a short time, by engaging sprockets spaced a constant distance with the link chain, moving the sprockets relatively and detecting the amount of a mutual shift of the sprockets. CONSTITUTION: When an electric motor 6 is driven, an engaging thread 2g of a sprocket wheel 2 and an engaging thread 3g of a sprocket wheel 3 are started to be engaged. When the wheel 2 rotates once and a measuring hole 4 reaches a horizontal position, a measuring point detection sensor 8 receives a light projected from a light-emitting element and passing the measuring hole 4, and detects the measuring hole 4. Similarly, a measuring point detection sensor 9 detects a measuring hole 5 of the sprocket wheel 3. If a link chain 33e in a first engagement route of the wheel 3 extends, a time difference is brought about in detection times of the sensors 8 and 9. A rotating angle detection sensor 7 counts the number of pulses in the time difference of the sensors 8 and 9 and, an operation circuit calculates the amount of the extension of the link chain from the counted number of pulses.

IPC: H04N5/76
Filed: 1985-06-20
Abstract: PURPOSE:To record even a reservation time which exceeds the time of the rest of a tape by switching automatically a recording speed mode from a short- time mode to a long-time mode at proper timing. CONSTITUTION:The reservation time set in a reservation time setting means 3 is converted into a voltage by using a converting means 4. The integral time obtained by integrating the time length of recording from the reservation by an integrating means 5 is converted into a voltage by a converting means 6.

Then, the 2nd voltage obtained by converting the time required to record the remaining tape in the long-time mode into a voltage is compared by a comparing means 8 with the 3rd voltage and when the difference reaches zero or a predetermined value, the comparing means 8 generates an output signal. A recording speed mode switching means 9 switches the recording speed mode from the short-time mode to the long-time mode by using the output signal of the comparing means 8.
