Abstract: The present invention is a method and apparatus for
centering a belt-shaped material. A conveying direction
leading end portion and a conveying direction trailing end
portion of triangular portions of the belt-shaped material
are displaced in advance in directions opposite directions
in which the conveying direction leading end portion and the
conveying direction trailing end portion of the belt-shaped
material are displaced when applied onto a forming drum.
Centering of a constant-width portion of the belt-shaped
material is carried out as follows. A width of the
constant-width portion of the belt-shaped material is
measured while the belt-shaped material is conveyed. In
accordance with the measured width, a distance between a
pair of guide portions which are disposed so as to be
movable in a widthwise direction of the belt-shaped material
is adjusted. The belt-shaped material is passed through a
space between the adjusted guide portions.

Abstract: A method for manufacturing a ceramic shell-and tube type heat exchanger provided with fins, includes the steps of: inserting heat transfer tubes (2) of sintered tubular ceramic into throughholes of tube plates (1a, 1b) of unsintered plate-like ceramic each having a plurality of the throughholes for fixing the heat transfer tubes inserted thereinto; standing the heat transfer tubes vertically to a floor surface; positioning the tubular plates at both the upper and lower end portions of the heat transfer tubes; disposing between the tube plates many fin plates (6) of unsintered ceramic so as to pile up the fin plates in the direction of a length of the heat transfer tubes, each of the fin plates including: a thin plate (6a) having a plurality of throughholes for fixing the heat transfer tubes inserted thereinto, and protrusions (6b) formed on the both edge portions of the thin plate; firing them so as to unitarily join them by the utilization of differences of firing shrinkage ratios among the heat transfer tubes, the tube plates, and the fin plates; and removing the protrusions from the fin plates. Deformation of heat transfer tubes in a process of firing join can be effectively controlled. A jig for positioning tube plates is not necessary upon firing join because the tube plates are supported by fin plated and can be positioned in a predetermined place. Fin plates function as fins for enlarging a heat transfer area outside heat transfer tubes by removing the protrusions after firing join.

Abstract: An ultrashort pulse laser apparatus of the this invention includes (1) a laser medium, (2) a laser resonator which stores the laser medium and externally extracts a laser beam, and (3) an excitation source for outputting an excitation energy to the laser resonator to excite the laser medium. The laser resonator includes (i) a plurality of resonant mirrors disposed on both sides of the laser medium to form a resonant optical path, and (ii) a phase dispersion compensation unit which includes two optical members respectively arranged on two light input/output surface sides of the laser medium on the resonant optical path and compensates phase dispersion of light in the resonant optical path. That is, the laser medium is disposed in the optical path between the two optical members of the phase dispersion compensation unit. With this arrangement, even when the laser medium is arranged almost at the center of the laser resonator to stabilize mode locking, the cavity length of the resonant optical path can be reduced. Therefore, the repetition frequency of laser pulses can be increased, and simultaneously, size reduction of the laser apparatus itself can be achieved.

Abstract: A plasma addressed liquid crystal display panel comprises a channel substrate (4) having plasma channels (20) in its upper surface thereof and an upper substrate (14) over the upper surface of the channel substrate. A first polarizer (50) is disposed over the upper surface of the channel substrate and transmits only light that is polarized in a first state. An electro-optic layer (10) preferably comprising liquid crystal material extends over the first polarizer and has a first condition in which it transmits light that is polarized in the first state without changing the state of polarization and a second condition in which it converts light that is polarized in the first state to a second state of polarization that is orthogonal to the first state. A second polarizer (16) is over the electro-optic layer and transmits only light that is polarized in the second state. When the electro-optic layer is in the first condition, the second polarizer blocks the light that is transmitted by the first polarizer, whereas when the electro-optic layer is in the second condition, the second polarizer passes the light that is transmitted by the first polarizer.

Abstract: The invention relates to a transmitting and receiving method and a radio system. In a transmitter the signals to be transmitted are spread coded in means and modulated by subcarriers in means. In a receiver (R) the signals are demodulated in means and submitted to multiuser detection in means by using the subcarriers to limit the number of detectable signals in the means. The receiver uses multiuser detection for reducing multiple access interference and correcting frequency-selective fading.

Abstract: An object language application (e.g., c++, JAVA, etc.,) is enabled
to issue a query over a view and to receive back, as query results,
handles to application type objects which can be further manipulated by
the application. A view is defined herein as a collection of a view
type, and a view type is defined as a class or type. In a preferred
embodiment, a tool is used by a programmer writing an application to
create object language class definitions that are based upon the view
type of the view referenced by the query. Upon receipt of the query
referencing a view type, a query engine generates a query plan that
builds mock (i.e., proxy) application type objects in memory based upon
the view types. The application objects have a form that is consistent
with the class definition for a type of object returned as a result. The
application can run methods on the application type objects or point to
other application type objects from the handles, to the application
objects, that are returned to the application; and these manipulations
will be understood by the query engine. In a preferred embodiment, query
rewrite optimizations are applied to the queries over views requiring
object building in order to optimize the evaluation of the query and the
building of view objects as query results. For example, when a query
over a view is analyzed and it is determined that the query is not
requesting a handle, and is not referencing a method, but only asks for
values, no objects are built. Also, if a query traverses a reference
type attribute, but the query can be transformed into a join or outer
join operation between relational tables, then no object building is
required. In these above described situations, the rewritten query can
be pushed down to the database management system of the data source for
resolution. If the query does request a handle or references a method,
then some object building is required. However, query rewrite techniques
can still be applied so that parts of the query are pushed down to the
DBMS to minimize the number of objects that are built.
