Abstract: The objective is to suppress a delay in the response of pressing force of an electric brake, when braking and non-braking are alternately repeated in an electric-brake control apparatus. An electric-brake control amount calculation unit of an electric-brake control apparatus according to the present disclosure calculates a control amount for securing a clearance between a brake pad and a brake disk, based on a position of the brake pad, calculated by a position calculator at a non-braking time, and secures the clearance by changing the control amount in two or more separate steps at a time when the braking is switched to the non-braking. As a result, it is made possible to obtain an electric-brake control apparatus that can suppress a delay in the response of pressing force of an electric brake, when braking and non-braking are alternately repeated.

Abstract: The electric-power conversion apparatus comprises: switching devices each permitting a current to flow therethrough or shutting off that current; a device temperature detector that detects a temperature of one or more of the switching devices; a cooler that cools down the switching devices; a cooling-medium state detector that detects a state of a cooling medium passing through the cooler; and a control unit that controls the switching devices to perform electric-power conversion, and performs overheat prevention control of the switching devices; wherein the control unit determines a temperature threshold value for judging whether the overheat prevention control is necessary or not, on the basis of the state of the cooling medium detected by the cooling-medium state detector, and performs the overheat prevention control by restricting operations of the switching devices, when the temperature detected by the device temperature detector is higher than the temperature threshold value.

Abstract: An electrical power conversion apparatus is provided in which a heat generation abnormality-state such as an abnormal state of a cooling device is determined earlier in its determination, so that it becomes possible to securely perform a protective operation even in the heat generation abnormality-state. A control device estimates a change rate of a temperature detection value on the basis of a switching-element loss calculation value of a semiconductor switching element(s) calculated at least based on an electric current detection value, and compares a temperature-detection change-rate calculation value calculated from a temperature detection value with a temperature-detection change-rate estimation value, so that a heat generation abnormality-state of the semiconductor switching element(s) is estimated.

Abstract: A measuring apparatus includes: a measuring section which performs an invasive blood pressure measurement, and which detects that a predetermined abnormal condition occurs in a blood pressure during the measurement; a detector which detects whether or not a zero point calibration is being executed on a transducer to be used in the measurement; and a notification controller which, in a case where the blood pressure measured by the measuring section is in the predetermined abnormal condition, controls whether an alarm is output or not, based on a detection state of the detector. The notification controller can select a first mode in which an alarm sound is output, or a second mode in which the alarm sound is not output, based on an elapsed time period from a predetermined timing relating to the zero point calibration, and an output from the measuring section.
