    • A projector has an image generating device for generating an image, and a housing, having the image generating device disposed therein and having an opening defined therein for emitting therethrough projection light representing the image from the image generating device. A projection mirror is mounted on an outer surface of the housing for reflecting the projection light to project the image onto a projection surface. An optical system is disposed in the opening for applying the projection light to the projection mirror. The projector also has a foreign matter detector for detecting foreign matter which enters a light path of the projection light between the optical system and the projection mirror.

    • Exemplary embodiments of the present invention include a light source unit in which lowering of an illumination intensity of an emitted luminous flux is reduced or prevented. A light source lamp unit includes a light source lamp having a light emitting section in which discharging emission is performed between electrodes, an elliptic reflector to emit a luminous flux radiated from the light source lamp in a certain uniform direction, and a secondary reflecting mirror provided on the opposite side of the light source lamp opposite from the elliptic reflector. A center of light emission C2 between the electrodes does not match a first focal point F1 of the elliptic reflector, a center of the source of reflected light C1 of the secondary reflecting mirror does not match the first focal point F1 of the elliptic reflector. The center of light emission C2, the first focal point F1, and the center of the source of reflected light C1 are disposed on a straight line perpendicular to a straight line connecting the first focal point F1 and a second focal point F2 of the elliptic reflector.

    • Disclosed are a method and an apparatus for protecting data on a storage medium by encrypting the data to be recorded on the storage medium with a password. This method comprises a step of, generating, for changing key data on each memory unit by one password, the key data, thereafter encrypting the key data with the password and writing the encrypted data to the storage medium, and a step of encrypting the data with the key data and encrypted data to the storage medium. The method further comprises a step of reading the encrypted key data from the storage medium, a step of decoding the encrypted key data with the password, and a step of decoding the data on the storage medium with the decoded key data. The encryption is done by using the key data generated separately from the password, and it is therefore feasible to prevent the password from being analyzed by decoding a cipher text.
    • 公开了一种通过用密码加密要记录在存储介质上的数据来保护存储介质上的数据的方法和装置。 该方法包括以下步骤:通过一个密码生成用于通过一个密码改变每个存储器单元上的密钥数据的密钥数据,然后用密码加密密钥数据并将加密数据写入存储介质;以及加密数据的步骤 密钥数据和加密数据到存储介质。 该方法还包括从存储介质读取加密的密钥数据的步骤,用密码对加密的密钥数据进行解码的步骤,以及用解码的密钥数据对存储介质上的数据进行解码的步骤。 通过使用与密码分开生成的密钥数据来完成加密,因此可以通过对密文进行解码来防止密码被分析。
