Patent number: 7434668Abstract: A brake cable connecting apparatus that prevents a connecting pin from falling out, and whereby it is unnecessary to adjust the insertion depth of the connecting pin. The brake cable connecting apparatus comprises a regulating projection in the strut to prevent over-insertion of a connecting pin. A cable connecting groove is formed in the plate-like brake lever and is supported on the strut by the two facing surface walls. Two resilient members are deformed to allow the connecting pin to move into a cable connecting groove if an inner cable is pulled to insert the connecting pin laterally bridged between two facing plates of the clevis of the brake cable. Further, a cable disengagement restriction portion prevents passage of the connecting pin if the connecting pin may potentially fall out from the cable connecting groove.Type: GrantFiled: October 6, 2005Date of Patent: October 14, 2008Assignee: Nisshinbo Industries, Inc.Inventor: Masami Fujiyama

Patent number: 7411408Abstract: This invention provides a solar simulator measurement method capable of high-accuracy measurements with fast-response photovoltaic devices as well as with slow-response photovoltaic devices, and a solar simulator for implementing the method. A flash having a pulse waveform with a flattened peak is generated from a xenon lamp. The flash is sensed by an irradiance detector, its irradiance measured, and the irradiance of the light source is adjusted to fall within a prescribed narrow range based on the detected irradiance value. Then, the flash with irradiance within the prescribed range irradiates photovoltaic devices under measurement, and the current and the voltage output by the photovoltaic devices are measured at multiple points while a load of the photovoltaic devices is controlled. This process is repeated with multiple flashes to obtain an I-V curve for the photovoltaic devices.Type: GrantFiled: June 16, 2006Date of Patent: August 12, 2008Assignee: Nisshinbo Industries, Inc.Inventors: Mitsuhiro Shimotomai, Yoshihiro Shinohara
