An electric mobility vehicle in a facility includes a mobility body having a wheel, a driving unit driving the wheel, and a seat for the user, and sensors, and the mobility body has a controller which controls the driving unit for at least one of automatic driving and automatic stopping by using detected data of the sensor, the controller is configured to be able to set a detection cancel area, which is an area where a part of the user can exist in front of the user, the electric mobility vehicle further includes a lower side sensor which detects an object to be avoided from under a footrest surface or from a front end portion of a footrest portion.

Electric mobility vehicle system in a facility

Disclosed herein is a pulse transformer that includes: a drum core including a winding core part and first and second flange parts provided at both ends of the winding core part in an axial direction; a plurality of wires wound around the winding core part; and a plate-like core fixed to the drum core so as to face a first surface of the first flange part that is parallel to the axial direction and a second surface of the second flange part that is parallel to the axial direction. A value of S/Sis 0.19 or more and 0.47 or less, where an area of the cross section of the winding core part that is perpendicular to the axial direction is Sand a facing area between the plate-like core and the first or second surface is S

Pulse transformer

A transformer that improves the DC superposition characteristic without incurring eddy-current losses. In the transformer, a part of a plate-like core opposing a top face of a flange of a drum core is formed with a first opposing portion opposing none of input and output terminals and a second opposing portion opposing the input and output terminals. A first gap is formed between the top face and the first opposing portion by a spacer. A second gap greater than the first gap is formed by a recess of the plate-like core provided so as to correspond to the second opposing portion. This allows magnetic fluxes to pass between the top face and the first opposing portion where the gap is formed and inhibits them from passing between the plate-like core and the input and output terminals where the second gap greater than the first gap is formed.

A drug ejecting apparatus has an ejection port and an element which generates energy for ejecting a drug from the ejection port; a drug containing unit is connected to the drug ejection apparatus, and contains the drug; a movable wall is attached to an end of the drug containing unit, and is displaced by difference between pressures inside and outside of the drug containing unit; and a control unit displaces the movable wall. The drug ejection apparatus is filled with the drug, and the inside pressure of the drug containing unit is put in a negative pressure state in advance of ejecting of the drug, by displacing the movable wall by means of the control unit.

Drug ejecting apparatus and control method thereof

A medicine ejection apparatus which ejects a medicine for medicating a user has a medicine ejecting unit, which has an element that generates energy for ejecting the medicine, a drive control unit which controls a drive start and a drive stop of the element, and an ejection amount determining unit, which determines a total amount of a medicine that is ejected from the medicine ejecting unit after the element performs a drive stop. The drive control unit enables the element to perform driving to eject an amount of medicine calculated from a difference between a set ejection amount and the total amount of medicine that has actually been ejected, when the total amount ejected, as determined by the ejection amount determining unit, is less than the set ejection amount.

Medicine ejection apparatus and control method thereof

A drug ejection apparatus comprises a drug ejection assembly having an ejection port and an element for generating energy for ejecting a drug through the ejection port, a drug container connected with the drug ejection assembly for holding the drug, a pressure sensor unit for sensing a pressure change in the inside of the drug container in correspondence with ejection of the drug through the drug ejection assembly, and a drive control unit for deciding driving conditions of the element for ejecting a prescribed amount of the drug by reference to an output level of the pressure sensor unit on driving the element under prescribed conditions.

Drug ejection apparatus, estimation of ejection performance thereof, and method of drug ejection

Provided is an ultrasonograph and the like capable of easily specifying defective parts of an ultrasound probe and appropriately treating the defective parts. A test method of an operation of an ultrasound probe that transmits and receives a signal of ultrasound for creating a diagnostic image in an ultrasonograph includes: bringing a test material into contact with the ultrasound probe and transmitting a first ultrasound from the ultrasound probe to the test material by a first transmitting circuit connected to the ultrasound probe; receiving, by a first receiving circuit connected to the ultrasound probe, a received signal of a reflected wave of the first ultrasound received by the test material and receiving, by a second receiving circuit connected to the test material, a received signal of the first ultrasound received by the test material; and comparing the received signals with each normal received signal stored in a memory and determining whether the operation of the ultrasound probe is normal or defective based on the comparison result.
