Patent number: 4922570Abstract: A vehicular windshield washer system in combination with a windshield wiper having a wiper arm. The washer system is comprised of a pair of washer nozzles mountd on the wiper arm and so directed to eject washer fluid to opposite sides of the wiper arm upon being supplied with washer fluid. The washer fluid from a washer fluid source is selectively supplied to the washer nozzles in accordance with movement of the wiper arm. The washer fluid is suppliable to one of the washer nozzles upon rotational movement of the wiper arm in one direction and to the other washer nozzle upon rotational movement of the wiper arm in the other direction. The rotational movements turn at a turning position of the wiper arm.Type: GrantFiled: July 6, 1988Date of Patent: May 8, 1990Assignees: Nissan Motor Co., Ltd., Jidosha Denki Kogyo Kabushiki KaishaInventors: Yuji Hirohama, Eiichi Ono, Yukiho Murata

Windshield wiper with means for adjusting force with which wiper blade is pressed against windshield
Patent number: 4777695Abstract: A control lever is driven by a driving unit to cause variation in tension of a coil spring and therefore variation in force with which a wiper blade is pressed against a windshield. The driving unit is disposed in an arm head and includes a geared motor, a male screw member in the form of a bolt and secured to an output shaft of the geared motor and a female screw member having an internally threaded socket portion screwed onto the male screw member and a sliding portion in the form of a rectangular bar and installed in a guide member for longitudinal movement but against rotation. The output shaft of the geared motor, male screw member and the female screw member are so arranged as to have axes in line with each other and exending longitudinally of the arm head.Type: GrantFiled: December 22, 1987Date of Patent: October 18, 1988Assignees: Nissan Motor Co., Ltd., Ichikoh Industries LimitedInventors: Haruo Okuda, Yukiho Murata -
Patent number: 4718139Abstract: A novel and useful automotive wiper device, of which the depression force can be adjusted with a compact mechanism for adjusting the depression force of the wiper blades. The automotive wiper device employes a plurality of springs exerting a biasing force on a wiper arm and a wiper blade against a vehicular window surface. At least one of the springs has an adjustable spring force. The adjustable spring is associated with an adjusting means which allows adjustment of the spring force thereof.Type: GrantFiled: September 4, 1986Date of Patent: January 12, 1988Assignees: Nissan Motor Company Limited, Ichikoh Industries LimitedInventors: Haruo Okuda, Yukiho Murata

Patent number: 4326667Abstract: An air conditioner of an automatic temperature adjusting type used particularly for controlling the air temperature within a passenger compartment of an automotive vehicle. According to the present invention, the air conditioner controls simultaneously the air flow rate of a fan providing the air supply, and an air mixing door which controls the flow of air through either a heater or a bypass around the heater. The control is such that over an intermediate portion of the adjustment range the fan and air mixing door are operated together whereas at end portions of the adjustment range the fan is adjusted without moving the air mixing door. This is achieved by use of a particularly convenient gear mechanism of novel design.Type: GrantFiled: December 18, 1980Date of Patent: April 27, 1982Assignee: Nissan Motor Company, LimitedInventors: Yukiho Murata, Yasushi Inoshita
