  • Publication number: 20200391327
    Abstract: A method for manufacturing an SiC wafer from an SiC ingot includes a verifying step of applying a test laser beam to the SiC ingot in a predetermined area with the focal point of the test laser beam set inside the SiC ingot at a predetermined depth from the end surface of the SiC ingot. The test laser beam has a transmission wavelength to SiC, thereby forming a test separation layer inside the SiC ingot at the predetermined depth. The test separation layer has a test modified portion where SiC is decomposed into Si and C and test cracks extend from the test modified portion along a c-plane in the SiC ingot. Whether or not the test cracks have been properly formed is verified. When verifying, the power of the test laser beam is changed to set a proper power at which the test cracks are properly formed.

  • Patent number: 10831996
    Abstract: A problem to be solved is to assist input of information by a user. An information processing device of one embodiment includes a keyword sequence generator generating a keyword sequence by performing morphological analysis on text data in natural language; a category information sequence generator acquiring category information corresponding to each keyword of the keyword sequence based on a database in which keywords are associated with category information and generating a category information sequence; the pattern extractor selecting a category information sequence pattern from category information sequence patterns according to correlation between the category information sequence and each category information sequence pattern; and a determiner comparing the selected category information sequence pattern with the category information sequence and generating presentation information according to a difference between the selected category information sequence pattern and the category information sequence.

  • Patent number: 10799987
    Abstract: Disclosed herein is a laser processing apparatus for forming a separation layer inside an ingot by applying a laser beam to an end surface of the ingot in the condition where the focal point of the laser beam is set inside the ingot, the laser beam having a transmission wavelength to the ingot. The laser processing apparatus includes a holding unit for holding the ingot, a moving unit for moving the holding unit in a direction parallel to the end surface of the ingot held by the holding unit, a laser beam applying unit for applying the laser beam to the ingot held by the holding unit, an imaging unit for detecting the position of the ingot in the direction parallel to the end surface of the ingot, and a height detecting unit for detecting the height of the end surface of the ingot held by the holding unit.

  • Publication number: 20190281718
    Abstract: A passenger protection control device for effectively preventing an infiltration of water into the interior of a case without the use of a sealant includes: a printed circuit board; a connector; and a case that accommodates such that, while a connection end surface with a wire harness of the connector is exposed, the printed circuit board is isolated from the outside. The case is formed by: a box shaped cover in which the periphery of a ceiling wall is enclosed by side walls and a floor surface is opened; and a rear cover that plugs the floor surface of the cover. The connector is installed in an opening provided in the side wall of the cover. The rear cover has a first standing wall projecting so as to face a connector in the portion of the cover in which the connector is installed. The first standing wall of the rear cover has a planar region in a head top part. The planar region has an inclined surface having a falling gradient facing outwardly from the cover.

  • Patent number: 4562424
    Abstract: An integrator circuit comprising reset means by which, when it is detected that an integrator output V.sub.p for an input analog signal coincides with a plus or minus reference value, the integral output is reset to the vicinity of the middle of the plus and minus reference values, in effect, without interrupting the integrating operation; a circuit which produces a pulse each time coincidence is detected; and a circuit which produces a direction signal indicating whether the coincidence results from an increase or a decrease of the integral input.The pulses produced in the state in which the direction signal is indicating an increase are counted up, and the pulses produced in the state in which the direction signal is indicating a decrease are counted down, whereby the precise integral value of the input analog signal can be detected.

  • Patent number: 4152716
    Abstract: A voltage dividing circuit comprises a plurality of series-connected insulated-gate FETs, each having its gate and drain short-circuited with each other and its source and substrate short-circuited with each other. A substrate in which one FET is formed is isolated from another substrate in which another FET is formed.
