  • Publication number: 20190162618
    Abstract: In order to provide a vacuum monitor that, even if a sensing mechanism is exposed to an atmosphere into which various types of material gases are introduced, enables the deposition of matter on the sensing mechanism to be prevented, and enables the lifespan of the sensing mechanism to be extended, there are provided a sensing mechanism that is in contact with an atmosphere inside a measurement space, and outputs an output signal that corresponds to a pressure inside this measurement space, and a heater that adjusts a temperature of the sensing mechanism, wherein a set temperature of the heater is adjustable.

  • Publication number: 20190153626
    Abstract: An object of the present invention is to provide a polyolefin fiber, particularly a core-sheath composite polypropylene fiber which is possible to be easily deformed corresponding to a stress applied from a direction perpendicular to a fiber axis, to be less fibrillated, and to have an excellent knot strength. The problem of the present invention is solved by providing the polyolefin fiber having a compressive strength of 30 to 51 MPa calculated by the following formula 1 when compressed and deformed by 30% with respect to a fiber diameter in a direction perpendicular to the fiber axis in each single fiber.

  • Publication number: 20010021973
    Abstract: In order to achieve a processor that does not require processing time for branching processing and is ensured the flexibility of the processing content, an adder adds a start address stored in start address parts and selected by a selector and a stored content (relative address) of a program counter to output a current execution instruction address. An execution unit executes an instruction of the address of a program storing part. A comparator compares the address with an end address stored in end address storing parts and selected by a selector. When the addresses are matched, the selectors are switched, and the program counter is reset, so that branching can be performed without requiring an instruction cycle. The start address storing parts are rewritten by a supervisory processor, where appropriate.

  • Patent number: 5103300
    Abstract: A camera of the type in which a rotary filter having color filter sections formed for three different colors is rotated between an image pickup and an object and the image pickup repeatedly stores one frame of a video signal therein. The camera comprising a rotation controller, a memory and an output controller. The rotation controller controls the rotation of the rotary filter in such manner that the image pickup scans by at least two frames of the video signal for a certain residence time during which each of the color filter sections is disposed between the image pickup and the object. The output controller controls the outputting of the video signal from the image pickup into the memory. The output controller inhibits the image pickup from outputting into the memory the first frame of the video signal during residence time.
