| 20100274704 | TRANSACTION MANAGEMENT DEVICE AND READABLE STORAGE MEDIUM - A transaction management device can executed, with a simple procedure, a plurality of if-done orders in parallel and can reduce the risk of the client. In the transaction management device, an order receiving unit receives buy and sell order application information from client terminals. An order information generation unit generates a plurality of order information groups for each of the items of the buy and sell order application information received by the order receiving unit, the order information groups each including: a first order for placing one of a buy order or a sell order at a first order price; a second order for placing the other one of the buy or the sell order at a second order price; and a stop order for placing the other one of the buy order or the sell order at the stop order price. The first order price, the second order price, and the stop order price are set to different values for each of the order information groups. A storage unit stores the order information groups generated in the order information generation unit. An execution information generation unit, when starting transaction processing corresponding to each of the order information groups, sets the first order to be valid, the second order to be invalid, and the stop order to be invalid. | 10-28-2010 |
| 20110161221 | TRANSACTION MANAGEMENT DEVICE AND READABLE STORAGE MEDIUM - A transaction management device of executing plural if-done-orders in parallel. An order information generation unit of the device generates plural order information groups each including a first order for placing one of a buy or sell orders at a first order price, a second order for placing the other of these orders at a second order price, and a stop loss order for placing the other of these orders at a stop loss order price. This unit acquires the upper limit price for transactions, the lower limit price for transactions, and the number of simultaneously generated order information groups, and calculates the first and second order prices in such a manner that the price difference between the first orders is constant, the price difference between the second orders is constant, and the price difference between the first and the second orders belonging to the same group is constant. | 06-30-2011 |

| 20080198465 | OPTICAL PICKUP DEVICE AND OPTICAL DISK DEVICE - An optical pickup device is disclosed. The device includes: a light source that emits a light beam of a predetermined wavelength of about 405 nm; an objective lens being a plastic lens provided with, on at least one surface, diffraction means of a zone diffractive structure suppressing generation of aberration to be caused by a temperature change, and has a numerical aperture of 0.82 or larger for gathering the light beam emitted from the light source with respect to an optical disk; and a collimator lens disposed between the light source and the objective lens, and derives a substantially-collimated light by converting an angle of divergence of the light beam emitted from the light source. | 08-21-2008 |
| 20100103801 | OBJECTIVE LENS, OPTICAL PICKUP APPARATUS USING THE SAME, OPTICAL RECORDING/REPRODUCTION APPARATUS USING THE SAME, AND METHOD OF CORRECTING ABERRATION USING THE SAME - Provided is an objective lens for which expressions 0.83<(p | 04-29-2010 |
| 20110069598 | OBJECTIVE LENS, AN OPTICAL PICKUP, AND OPTICAL INFORMATION RECORDING/REPRODUCING APPARATUS - An objective lens has a numerical aperture of 8.0 or more and focusing a light beam of a wavelength λ of at least 450 nm or less on an optical information recording medium. In this objective lens, a wavefront-aberration deterioration level TOR, accumulative value of aberration deterioration, satisfies the equation (1): | 03-24-2011 |
| 20110110217 | OBJECTIVE LENS, OPTICAL PICKUP AND OPTICAL DISC APPARATUS - An objective lens is made of a resin material and focuses incident rays, which have a wavelength of 410 nm or less and are emitted from a light source, on an optical disc at a numerical aperture of 0.8 or more, wherein when a lens tilt sensitivity is defined as an amount of a 3rd-order coma aberration caused per a lens tilt of 1 degree which is an angle formed between an optical axis of the objective lens and a system optical axis of an optical system including the objective lens at 0° C., the lens tilt sensitivity is 130 mλrms/degree or less. | 05-12-2011 |
