Title: Terminal and communication method
Inventor: NUNOME TOMOYA
IPC: H04W72/04
Filed: 2019-04-04
Abstract: Provided is a terminal which can suitably apply precoding to a PDCCH. In the terminal (100), when a first CC is notified of scheduling information for each of a first component carrier (CC) and a second CC, a restriction determination unit (105) determines, on the basis of a subcarrier interval of the CC to be scheduled by means of the scheduling information among the first CC and the second CC, the maximum number of blind decodings when the scheduling information is blind-decoded. An extraction unit (102) performs the blind decoding on the basis of the maximum number of blind decodings and extracts the scheduling information.

Abstract: [Problem] To improve the quality of a water pump device. [Solution] In a pump housing 22, an opening 47a serving as a steam vent hole is provided in a second boss portion 46 having a point P1 that is the shortest distance thereof from the inner circumferential surface of a pump pulley 28, and in the vicinity of the outer edge portion of the opening 47a, an extension piece 47b that extends in the same direction as the extension direction of the second boss portion 46 is provided rearward in the rotating direction of the pump pulley 28 in relation to a virtual line VL. Thus, in association with the rotation of the pump pulley 28, the airflow produced in a space 92 between the inner circumferential surface of the pump pulley 28 and the outer circumferential surface of a main boss portion 42 including a first boss portion 44 and the second boss portion 46 hits the extension piece 47b and the pressure around the opening 47a becomes higher than the pressure in other sections. As a result, regardless of the placement of the opening 47a, it is possible to suppress the occurrence of a differential pressure between an opening 44b and the opening 47a, and also possible to well suppress the entry of foreign substances and the like into a space 70 from the outside.
