  • Patent number: 11879461
    Abstract: An oil pump includes: a shaft member; an inner rotor configured to rotate integrally with the shaft member; an outer rotor forming a rotor chamber into which oil is sucked from a suction passage and from which the oil is discharged toward a discharge passage, between the inner rotor and the outer rotor; a body member having a recess-shaped housing chamber in which each rotor is housed so as to be rotatable about an axis; and a cover member attached so as to close the housing chamber. The rotor chamber has first and second suction ports through each of which the oil to be sucked from the suction passage passes. The oil pump includes a straightening member branching the suction passage from a main path to the first suction port side and the second suction port side.

  • Patent number: 11040280
    Abstract: A game processing method that causes a computer to execute a game program includes displaying, with a touchscreen, a reference operation and a deck that comprises an item, receiving a first input operation to select the deck and second input operations, determining a matching degree between the reference operation and each of the second input operations, outputting, from a processor to a memory, a level of the matching degree based on the determination, counting, with the processor, a number of consecutive times that the level continuously exceeds a predetermined threshold level, calculating, with the processor, a score of the user based on the number, and outputting, from the processor to the memory, the score. When the item comprises a card having a predetermined effect and continuation of exceeding the predetermined threshold level is interrupted, the number is counted as if no interruption has occurred.

  • Patent number: 10302185
    Abstract: In an oil passage structure for a power transmission device including a case provided to accommodate a power transmission device, a baffle plate attached to an inner wall of the case, and an oil pump, the oil passage structure includes a supply oil passage through which oil is pumped from the oil pump to an oil supply destination via the baffle plate. The baffle plate has a structure in which two members of a plate body and a plate-shaped auxiliary member are superposed and integrated with each other. The baffle plate is provided with a plate oil passage that constitutes a portion of the supply oil passage and passes through the inside of the baffle plate. The plate oil passage is formed by a recess provided in at least one of a surface of the plate body and a surface of the auxiliary member which face to each other such that the auxiliary member is interposed on the plate body.
