Title: Method of monitoring controllability of phase control circuit
Inventor: BUORUFURAMU ERUNSUTO
IPC: H03L7/095
Filed: 1990-01-31
Abstract: PURPOSE: To quickly evaluate the controllability of a phase control circuit and to set an alarm threshold to a low level even when the input side allowable frequency jump of a phase discriminator is large. CONSTITUTION: At the time of monitoring the gradient of a phase difference PD to discriminate frequency jump, a 1st time interval element TU1 having a 1st time interval T1 sets a gradient threshold in relation to a relative threshold FS. Phase is corrected every time when the gradient threshold exceeded and the element TU1 is newly started, i.e., a state that the gradient threshold is newly exceeded is monitored. Thereby the output signal OUT of the phase discriminator exceeds the alarm threshold due to frequency jump and the trigger of a synchronizing alarm is blocked even if the phase control circuit is normally driven. This means that the alarm threshold can be set to an extremely low level without depending upon the level of the allowable frequency jump.

Title: Reduction gear
Inventor: MATSUNAGA KATSUO
IPC: F16H1/32
Filed: 1987-01-29
Abstract: PURPOSE:To ease the hole machining work, by providing an eccentric circular cam, which is firmly fixed to an input gear, a planet gear, which substantially receives this eccentric circular cam in both closely and in freely and relatively rotatable manner, and an internal gear, which is engaged with this planet gear in an inscribed state and which is supported by an input gear concentrically with the input gear, in addition to a connecting member. CONSTITUTION:A shaft of an input gear 15 and an output shaft 8 can face an axial direction that is common to both shafts. Therefore, the direction of hole machining, which is performed to form a bearing or the like for the input or output shaft, can be the same, thereby easily obtaining the hole machining of high accuracy. In addition, when an internal gear 18 is supported in a freely rotatable manner, a planet gear 19 can revolve round the sun gear owing to a connecting member 22. As a result, the transfer of the torque from the input gear 15 toward the output shaft 8 is suspended. Accordingly, when an electromagnetic unit 32 is used as a fastening means, the on-off control over the torque- transfer can be carried out without changing the engaging condition of the gears.

Abstract: PURPOSE:To reduce the error for the drift of a pressure sensor, by making the state of zero differential pressure of a pressure sensor on condition that an ignition switch is closed and the number of revolutions is lower than a certain value and using this pressure as a reference to detect a differential pressure. CONSTITUTION:When a vehicle is stopped and the output of an FV converter FV is low-level, the short-circuit state of a pressure sensor 10 is made.

At this time point, a sample holding circuit S & H holds the output of a differential pressure sensor which is in the short-circuit state. Hereafter, a differential amplifier AMP 3 outputs a difference e2=e1-e0 between a held voltage e0 and an output e1 of the differential pressure sensor 10.
