A display device includes at least one pixel including a plurality of sub-pixels, and a linear sensor electrode extending along a boundary of the plurality of sub-pixels and surrounding a periphery of the at least one pixel. The sensor electrode has at least one cut-off portion at the boundary of the plurality of sub-pixels. The sensor electrode can include a first sensor electrode extending along the boundary of a plurality of sub-pixels and a second sensor electrode that surrounds the periphery of at least one pixel continuous from the first sensor electrode, and the cut-off portion can be located at the boundary of the first sensor electrode with the second sensor electrode.

For the purpose of providing a particle beam therapy apparatus which is unnecessary to be separately verified for operational integrity of its dose monitors and is unnecessary to have an additional failure diagnosis function, a particle beam therapy apparatus is so configured that, by a dose-monitoring system controller, the main and sub roles of two dose monitors are switched therebetween at every radiation and their corresponding dose monitor circuits are controlled accordingly, so that operation checking of the two dose monitors can be performed during a therapeutic flow, without the need of a special operation.

Particle beam therapy apparatus

A Si diode is used as a rectifying diode on a transformer secondary side of an isolated DC/DC converter, and a high-voltage Schottky barrier diode made of a wide bandgap semiconductor is used as a free-wheeling diode arranged between a rectifier circuit and a smoothing reactor. Thus, there may be provided an in-vehicle charger capable of suppressing a diode recovery surge voltage with a circuit configuration that is simpler and suppressed in cost increase as compared to a case where a related-art synchronous rectifier circuit system is employed.

In-vehicle charger

Plural equipment control devices of a particle beam therapy system comprise an equipment operation parameter calculation unit calculating equipment operation parameters based on data given by equipment data servers individually and an equipment operation verification data generation unit generating equipment operation parameter verification data for verifying soundness of the equipment operation parameters, an equipment data server comprises an equipment operation parameter integrating calculation unit calculating so as to obtain equipment operation parameters of each equipment, an equipment operation parameter verification data integrating generation unit generating an equipment operation parameter verification data of each equipment for verifying soundness of equipment operation parameters of each equipment, and a verification data comparison unit comparing equipment operation parameter verification data of each equipment which is received from plural equipment control devices with equipment operation parameter verification data of each equipment which is generated by the operation parameter verification data integrating calculation unit.

Particle beam therapy system

A method and device for safety protection of a secondary battery capable of preventing smoking and ignition thereof. A lithium cellas a chargeable and dischargeable secondary battery, a protection circuitfor shutting down charging power Pc at the time of overcurrent, overvoltage, etc., and an electric power restriction circuitfor limiting the charging power Pc input to the lithium cellare incorporated into a battery pack. A battery charger, equipped with a stabilized electric sourceand a charging circuit, inputting the charging power Pc to the lithium cell, is connected to a previous stage of the battery pack. The electric power restriction circuitlimits the charging power Pc within a boundary value Pmax of a safety operation region for safely using the lithium cell, thereby permitting the lithium cellto operate safely under any conditions.

Method and device for safety protection of secondary battery

A paper punch apparatus comprising a flange-storing space for storing the flange portion in an elevating unit, an insertion/removal portion for insertably supporting a supporting axis of a bit reception plate in communication with the flange portion, and a bit-reception-plate engagement/disengagement portion for engagement/disengagement with respect to the flange portion of the bit reception plate in the flange-storing space, so that the bit reception plate can be parallelly and linearly inserted/detached with respect to the elevating unit, insertion/detachment can be steadily and securely performed at all times, whereby the apparatus is simple in structure, inexpensive, and excellent in, for example, paper punch functions, handling functions for a hole punch bit(s), bit reception plate(s), punched-paper-scrap discharge functions, and punch-position adjustment functions, and further the punch apparatus enables quality improvement, cost reduction, and the like to be implemented.

Paper punch apparatus

An apparatus for calibrating a pulse oximeter which can improve the repetitivity of measured values for calibration tests and which can calibrate the pulse oximeter with a high reliability. A tissue model having a light-absorbing characteristic approximated to that of the tissue of a living body is inserted into a space between a light-emitting section and a light-receiving section of a measuring probe that is connected to the pulse oximeter, and a blood model having a light-absorbing characteristic that is approximated to that of the blood is moved within the tissue model so as to enter into or exit from the space between the light-emitting section and the light-receiving section.
