IPC: G01D1/18
Filed: 1990-11-27
Abstract: PURPOSE: To restrain occurring noise by determining a reference value based on a given part of one cycle of a signal, in a device which compares signal amplitude of a cyclic signal with the reference value following a signal value prior to this signal and outputs a trigger signal when it reaches the reference value. CONSTITUTION: In a circuit device 1 having a trigger circuit 2 which processes a cyclic signal S from a inductive needle movement sensor 3 placed on an injection valve of an internal combustion engine, the cyclic signal S is compared with a reference voltage REF proportional to a peak value of a first half wave in a cycle prior to the signal S with a comparator K2.

Title: Hydromechanical transmission
Inventor: KINOUE KENJI
IPC: F16H47/04
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To display the same or more efficiency as AT transmission even at the specific number of revolution, while maintaining a higher efficiency than the AT transmission at the nearly entire area of a variable speed change range. SOLUTION: At a specific number of revolution time, the slant plate VM of a hydraulic motor M is rendered to a neutral position and HST is rendered to an idle rotation state and a torque from HST to an output shaft O is not transmitted.
