Cooling air conveyed through a cooling ductis supplied to a discharge lampvia a cooling air exithaving a plurality of flow pathstopartitioned by a partition plateAn air flow direction changeover sectionchanges a flow path through which the discharge lamp is supplied with the cooling air from the cooling air exit. An air flow blocking ballin the air flow direction changeover section moves by its own weight through a guide portionto thereby block the flow path of the cooling air exit. This allows the cooling air to be directed specifically toward an upper sidein a direction of gravity of a lamp bulb of the discharge lamp to eliminate a temperature difference, even if a mounting style of the discharge lamp is varied among desk mounting, ceiling mounting, and vertical mounting.

A projection type image display apparatus for projecting optical fluxes from a light source onto a projection plane so as to display an image, provided with a reflection mirror arranged in such a manner that the reflection mirror interrupts an optical path of the projection light in the direct projection mode when the reflection mode is set and reflects the projection light to the backside of the projection type image display apparatus, and when the reflection mode is set, the projection type image display apparatus is tilted to the backside. The projection type image display apparatus is further provided with an adjustment leg arranged in a front portion of a bottom plane of the projection type image display apparatus and extended by a predetermined leg length, and thereby the projection type image display apparatus is tilted to the backside.

Copy pair monitoring is provided for a storage system having plural host computers, at least one storage subsystem, and a management computer. The storage subsystem including volumes storing data requested by the host computer, the management computer being accessible to the host computer and the storage subsystem. The copy pair monitoring includes obtaining every piece of copy pair definition information that is stored in the host computer, removing duplicate copy pair definition information from the whole copy pair definition information obtained, and collecting the copy pair status based on the obtained copy pair definition information from which duplicate copy pair definition information has been removed. Each host computer is assigned a priority level, and, when more than one host computer includes the same copy pair, the host computer with the lowest priority obtains the copy pair information to reduce the load on the higher priority host computers.

Method of improving efficiency of replication monitoring

Provided is a copy pair monitoring method which is for a storage system having at least one host computer, at least one storage subsystem, and a management computer, the storage subsystem including volumes storing data requested by the host computer to be written, the management computer being accessible to the host computer and the storage subsystem. The copy pair monitoring method is characterized by including the steps of: obtaining every piece of copy pair definition information that is stored in the host computer; removing duplicate copy pair definition information from the whole copy pair definition information obtained; and collecting the copy pair status based on the obtained copy pair definition information from which duplicate copy pair definition information has been removed.

A projection type image display unit has a housing on which a light source and an image display part for transmission or reflection of light from the light source are mounted. The unit includes a position adjusting device, by which a displayed position of an image is adjusted. The position adjusting device comprises: a manipulation member being vertically movable with a part thereof projecting from a side of the housing; a leg member projecting from a bottom of the housing and adapted to freely vary an amount of the projection thereof; and a connecting member connecting the manipulation member with the leg member to set the amount of the projection of the leg member by manipulating the manipulation member in a vertical direction. The connecting member comprises a lever member so that a movement direction of the manipulation member becomes the same as a movement direction of the housing and a movement amount of the manipulation member substantially becomes the same as a movement amount of the housing.

A frosting agent in which particulate silica suspends with high dispersibility without lowering the flow-out and formability of an aqueous polyurethane as a binder of frosting coating agent. Such a frosting agent for use in an aqueous polyurethane is obtained by adding 0.5-5.0 parts by weight of .gamma.-ureidopropyltriethoxysilane and 0.1 part by weight or more of water to 100 parts by weight of particulate silica and reacting said substances at a temperature of 15.degree.-100.degree. C. to modify the surface of said particulate silica. By this reaction, .gamma.-ureidopropylsilane liberated by hydrolysis of ethoxysilane groups reacts with acid hydroxy groups. Thus, the wettability and compatibility of the frosting agent with respect to aqueous polyurethane increases. This improves the dispersibility and the resistance to scuff of the coating.
