Patent number: 5400664Abstract: In an automatic analyzer such as blood analyzer, it is important to observe whether the sample, such as a blood sample, is sucked correctly or not. In an apparatus for observing suction of a sample, comprising a sample suction tube, a luminous element for emitting light toward the sample suction tube being driven by a driving circuit, a photo sensor for receiving the light from the sample suction tube, and a judging circuit for judging the sample suction on the basis of the signal from the photo sensor, a controller is provided in order to drive the luminous element so that the output (Vp) of the photo sensor may be nearly the reference value (Vr) before a sample suction, and to drive the luminous element so as to hold the driving state during the sample suction. Thus, the sensitivity adjustment of the apparatus for observing suction of a sample may be automated, and the observing capability of the apparatus is enhanced.Type: GrantFiled: July 27, 1992Date of Patent: March 28, 1995Assignee: Toa Medical Electronics Co., Ltd.Inventor: Katsuhiko Kio

Patent number: 5381687Abstract: An escalator combplate is equipped with a stop switch that will interrupt the power to the escalator when objects trapped between the stop treads and combplate impose a predetermined lifting force on the combplate. The necessary lifting force is determined by code requirements, and the combplate is subjected to an upward spring force which equals the code-dictated lifting force. While the combplate is being lifted by the spring force, the stop switch or switches are set so that they will actuate at the calibrated position of the combplate. The spring force is then removed to allow the combplate to settle back to its normal operating position.Type: GrantFiled: October 19, 1992Date of Patent: January 17, 1995Assignee: Otis Elevator CompanyInventors: Dat Nguyen, James A.
