An imaging lens substantially consists of six lenses of a negative first lens, a negative second lens, a positive third lens, a positive fourth lens, a negative fifth lens and a positive sixth lens in this order from an object side. An object-side surface of the second lens has a shape having negative refractive power at a center, and including a part having positive refractive power in an area between the center and an effective diameter edge, and having negative refractive power at the effective diameter edge (concave shape facing the object side), and the refractive power at the effective diameter edge being weaker than the refractive power at the center. Further, an object-side surface of the third lens is convex toward the object side.

This invention relates to a method and apparatus for separation of rare stable or radioactive isotopes from their atomic or molecular isobars in mass spectrometry (MS). In the present invention, the approach taken to removing atomic isobars utilizes a high transmission device for decelerating ions in combination with low energy reactions, such as ion-molecule reactions or near resonant electron transfer, in RF ion guides. The isobar is selectively depleted by electron transfer or other reactions between negative ions and gaseous targets in pressurized RF ion guides at low energies. The energy is controlled in such a way as to prevent reaction of the ion of interest while inducing reactions with the undesired isobar interference. The technique is of particular relevance to accelerator mass spectrometry (AMS) for which it allows substantial reductions in the necessary terminal voltage. The effect is to allow reductions in the size and cost of AMS installations.

A predetermined conditional formula about a combined focal length of the fourth lens and the fifth lens is satisfied.

A FET of a power supply reverse connection protection section is connected between a battery and an electronic device, and at a time of reverse connection of the battery, the FET is turned off and a parasitic diode of the FET prevents a current flowing in a direction opposite to a direction at a time of normal connection. A transformer is used in a DC / DC converter of a first power supply section that supplies power to a control section, and a voltage generated in a secondary winding is applied to the FET.

An electric power steering apparatus includes a power supply and a power supply management unit that controls an operation of the power supply. The power supply includes a main power supply, an auxiliary power supply connected in series to the main power supply, a boost circuit that charges the auxiliary power supply by boosting an output voltage of the main power supply and applying the boosted output voltage to the auxiliary power supply, and a voltage sensor that detects an output voltage of the auxiliary power supply. When a reduction amount per unit time of the output voltage detected by the voltage sensor exceeds a voltage reduction amount over a predetermined time, the power supply management unit determines that an abnormality has occurred in an output destination of the power supply.

In a gaming table (1), image light L1 emitted from a display surface of a liquid crystal module (2) that carries out a dual image display arrives, directly through a window of a frame (4b), at a player in front of the gaming table. Image light L2 emitted from the display surface of the liquid crystal module (2) is reflected by a reflecting surface of a mirror member (3) so as to also arrive at the player through the window of the frame (4b). The player recognizes a first image formed from the image light L1 and a second image formed from the image light L2. Thus, the first and second images are supplied to the player as a background image on the gaming table (1). This makes it possible to realize a gaming machine having a display device that can display a large screen and can reduce the size and cost of the gaming machine.
