Abstract: Provided is technology that makes it possible to design a progressive power lens appropriate for visual behavior of a subject. A method for designing a progressive power lens includes: a step (a) of determining a relationship between a line-of-sight passage position on a surface of a progressive power lens through which a line of sight of a subject wearing the progressive power lens passes and a reactive accommodation amount that the subject exhibits when the line of sight passes through the line-of-sight passage position, based on visual behavior of the subject; a step (b) of judging whether or not the reactive accommodation amount is within an appropriate range; a step (c) of determining a correction method for correcting the progressive power lens based on a result of judgement made in the step (b); and a step (d) of correcting a design of the progressive power lens based on the correction method determined in the step (c).

Abstract: A motor is contained in a motor container space. A controller is contained in a controller container space. The motor container space and the controller container space are arranged in series in a direction of a rotation axis of a motor shaft, while interposing a partition wall therebetween. The motor shaft is inserted in a motor shaft through-hole of the partition wall. A magnet is disposed at an end of the motor shaft, in the controller container space. A rotation sensor is disposed in the controller container space oppositely to the magnet, for monitoring a rotational position of the motor shaft on the basis of variation in magnetic field due to rotation of the magnet. A cover made of nonmagnetic metal is disposed between the magnet and the rotation sensor so as to cover the motor shaft through-hole.

Abstract: A liquid crystal display device includes plural reflective electrodes supplied with a video signal, second light-blocking conductive films below the reflective electrodes with a first insulating layer therebetween, and a first light-blocking film below the second light-blocking conductive films so as to cover spacing between the second light-blocking conductive films. Each of the second light-blocking films is electrically connected to a corresponding one of the reflective electrodes, and is disposed to cover at least a portion of spacings between the corresponding one of the reflective electrodes and ones of the reflective electrodes adjacent thereto. A second insulating layer is interposed between the first and second light-blocking films, and its thickness is from 150 nm to 450 nm.

Abstract: An electronic mail system is provided that can control suppression of a transmission band and a storage area of a mail, and can communicate all contents of a mail transmitted from a sender to a receiver. The electronic mail system is provided with a transmission apparatus (1) and a reception apparatus (2). The transmission apparatus (1), when transmitting a mail A with a signature added, transmits a mail A′ whose size is made smaller by converting the signature to a signature ID. The mail A′ is held in a mail server 4 through a mail server 3. The receipt apparatus 2, when receiving the mail A′ from the mail server 4, restores the mail A by converting the signature ID in the mail A′ to the signature.
