Abstract:
A moisture-proof container including: a container body; a lid hermetically closing the container body to be openable and closable; and a desiccant storage case that is put on a bottom portion of the container body. The desiccant storage case includes: an inner case having an opening at one end; a desiccant stored in the inner case; and a moisture transmission dustproof sheet to seal the opening of the inner case. The inner case has, at an outer circumferential wall thereof, a groove connecting between an open end and a bottom portion, the container body includes a base on a bottom plate, and the desiccant storage case is put in the container body such that the moisture transmission dustproof sheet abuts the base, and a gap is formed between the bottom plate of the container body, and the moisture transmission dustproof sheet.
Abstract:
An infrared spectrophotometer, which is capable of preventing measurement data measured from being adversely affected by moisture vapor. An internal space of an attachment receiving therein an optical element is sealed and isolated from ambient air by providing a tube and others, and a dehumidifier is provided in the internal space of the attachment for an optical path. Thus, the dehumidifier is disposed in a relatively narrow space, so that the internal space of the attachment can be efficiently dehumidified within a short period of time so as to reduce humidity in the internal space to suppress absorption of moisture vapor which would otherwise occur on the optical path in the internal space of the attachment. This makes it possible to prevent a negative influence of moisture vapor on measurement data, while reducing a standby time due to the dehumidification.
Abstract:
A rear projection type image display apparatus having an arrangement that a projection distance of a projection lens thereof is shortened and a density of mounting of parts relating to an optical system and an electric system is made higher. Furthermore, a width of a rear portion of a housing of the rear projection type image display apparatus is reduced rearwards at any position from the upper portion to the lower portion thereof, and the lower portion of a back cover is depressed inwards. Thus, a space required to install the rear projection type image display apparatus can be reduced, the rear surface of the apparatus can be disposed on a wall without any gap when the apparatus is installed along the wall, and the overall body of the apparatus can be received deep into a corner of walls when the apparatus is installed at the corner.
Abstract:
Disclosed is a projection lens system for use in an optical system for magnifying and projecting original images displayed on plural image display devices onto a screen through projection lenses provided in corresponding relation to the image display devices, which projection lens system comprises plural lens elements and in which according to colors or degrees of fineness of original images, the number of constituent lenses, or the shape of lens surface, or an effective aperture of at least one constituent lens element surface, or the number of constituent lenses and the shape of lens surface, or the number of constituent lenses and an effective aperture of at least one constituent lens element surface, or the shape of lens surface and an effective aperture of at least one constituent lens element surface, or the number of constituent lenses, the shape of lens surface and an effective aperture of at least one constituent lens element surface, are changed at a time.
Abstract:
A power window control apparatus has a transmitter, detachably mounted to a fixed member in a compartment, for transmitting coded infrared ray signals corresponding to opening/closing operations of right and left windows of a vehicle and a receiver fixed in the compartment, the receiver being provided with a manual switch for driving the relay circuit independently of the signal from the transmitter, a reset circuit for resetting the decoder for a predetermined period of time after an ignition switch is turned on, and a braking circuit for braking a corresponding one of motors when a driver releases a transmitter switch.
Abstract:
An automatic message announcement system for announcing the approach, arrival, and departure of vehicles such as trains at a train station. An addressable voice memory is provided for storing sequences of voice segments which are read out upon receipt of announcement command input signals to form messages for announcing that a vehicle is approaching or has arrived or is departing, with specific information such as the vehicle's destination being included in the announcement by inserting the appropriate voice segments at the proper points in the sequence. The messages are composed in such a manner that the sequences of voice segments can be altered to form shorter, but still intelligible, messages if vehicles traffic is so heavy that one message is due for announcement before the previous announcement is completed. A priority selection circuit is provided for giving priority to the announcement command input signals, along with a memory for storing the addresses of the voice segments, a control circuit for reading out the memory content on the basis of the announcement command input signals and generating a message pattern to be announced, and an edition control circuit for supplying the appropriate addresses to the voice memory so that the proper voice segments can be read out in the desired sequence in order to produce the announcements.

Abstract:
In order to manage a plurality of sets of multidimensional data positioned in a specific area of a computer, when hierarchically dividing a first area within the specific area into second areas that are to constitute child areas thereof, a decision is made as to whether or not a division condition, which is based upon the state achieved when the sets of multidimensional data are allocated to the first area and the state achieved when the sets of multidimensional data are allocated to the second areas, is satisfied. When it is decided that the division condition will be satisfied, the first area is hierarchically divided into the second areas to allocate the sets of multidimensional data to the second areas.
