Abstract: A wiper control device that properly detects restriction of a wiper blade according to a travel distance of the wiper blade. When a state in which a rotation speed of an output shaft calculated from a rotation angle of the output shaft detected by a rotation angle sensor is equal to or slower than a speed threshold defined according to a travel distance of the wiper blade and in which a current detected by a current detector is equal to or larger than a current threshold continues for a predetermined determination period, a microcomputer stops a wiper motor or reverses a direction of a wiping action of the wiper blade.

Abstract: A wiper motor control circuit carries out control in which a driving circuit generates, and supplies to a wiper motor, a voltage that eliminates deviation between a target speed and an actual speed of an output shaft. In a case in which a state in which the deviation between the target speed and the actual speed is greater than or equal to a predetermined threshold value continues for a predetermined time or more, the wiper motor control circuit carries out control that lowers the target speed and in which the driving circuit generates, and supplies to the wiper motor, a voltage that eliminates deviation between the lowered target speed and the actual speed of the output shaft.

Abstract: A balloon catheter including an elongated catheter main body portion and a balloon provided on the distal portion of the catheter main body portion. The balloon is inflatable to expand radially outward into an inflated state and deflatable to contract radially inward into a deflated state. The catheter main body portion includes a hollow outer tube and a hollow inner tube disposed within the outer tube. The balloon includes a contact portion that contacts the outer surface of the inner tube and a vane portion protruding from the contact portion radially outward when the balloon is in the deflated state. The contact portion of the balloon includes a connecting portion that connects the balloon to the catheter main body portion.

Abstract: A balloon catheter which can rather smoothly move inside living body organs, and can improve trackability and pushability. The balloon catheter has an inner shaft that includes a guidewire lumen into which a guidewire can be inserted, an outer shaft that forms a fluid lumen for introducing a fluid on an outer periphery of the inner shaft, a membranous material that causes a space portion into which the fluid can flow to communicate with the fluid lumen, and that partitions the space portion on the outer periphery of the distal portion side of the inner shaft, and an inflatable and deflatable balloon in which a lumen into which the fluid can flow is formed on an outer periphery of the membranous material.

Abstract: Each of a plurality of nozzles is placed to correspond with a corresponding one of a plurality of washing subjects of a vehicle and is adapted to spray washer fluid over the corresponding one of the washing subjects upon receiving the washer fluid from a pump. A switch valve is adapted to switch a supply destination of the washer fluid, which is pumped from the pump, among the nozzles. A control conduit is placed in a flow path between an inlet of the switch valve and an outlet of a corresponding one of the nozzles and limits a flow quantity of the washer fluid, which is fed from the switch valve to the outlet of the corresponding one of the nozzles.

Abstract: A vehicle wiper device including a wiper arm, a wiper blade, and a wiping range enlarging mechanism is disclosed. The wiper arm is driven by driving force of a drive source. The wiper blade is coupled to a distal portion of the wiper arm at a constant position relative to the wiper arm. The wiper blade moves back and forth between first and second reversing positions while wiping a wiping surface of a vehicle body when the wiper arm is driven. The wiping range enlarging mechanism drives the wiper arm while moving a basal portion of the wiper arm so that a wiping angle of a basal portion of the wiper arm becomes greater than a wiping angle of a distal portion of the wiper arm at the second reversing position.

Abstract: An arm main body is rotatably connected to an arm head. A spring urges a distal end portion of the arm main body toward a wiping surface to urge a wiper blade toward the wiping surface. The arm main body includes a receiving recess, which receives the spring and the arm head. The spring is placed on a side of a fixing portion of the arm head where the distal end portion of the arm main body is located. The arm main body is rotatably connected to the arm head at a location that is spaced from the spring on a side opposite from the distal end portion of the arm main body.
