Patent EP-0814596-A2 (EP)
Title: Scanning system
Inventor: SCHMIDT JACK H
IPC: G02B17/08
Filed: 1997-06-04
Abstract: In a system for scanning a document (43), a light source (22) illuminates the document; an imager (24, 41, 41', 61, 62) receives light from the document and directs it toward a detector array (25) which produces a corresponding array of electrical signals. The imager has several optical properties that are useful either individually or in combination. The imager is telecentric and thereby ensures that image size and magnification are insensitive to object displacement along the optical axis (46, 46') and image brightness is uniform independent of object off-axis distance. An aspheric element (33) within the imager balances focus variation (82-81-83) within the depth of field with spherical aberration and thereby provide nearly uniform image resolution. A diffraction pattern (33'), carried by the imager, corrects for spectral dispersion which occurs when light passes (63) from air into a refractive material (61, 62). An imager with a reflecting surface (32, 33) provides a system that is subject to little or no chromatic aberration. A solid imager (61, 62) with multiple internal reflecting surfaces (32, 33, 42) in optical series (32-33-32-42), configured to include the previously mentioned optical properties, also provides for highly stable alignment of reflecting surfaces.

Abstract: The present invention relates to the improvement of metal bonding strength in
polypropylene films through the addition of ethylene in a mini-random ethylene-propylene
copolymer in an amount of no more than about 1 weight percent, more preferably no more
than about 0.7 weight percent, and most preferably between about 0.3 weight percent and
about 0.5 weight percent, or even amounts between about 0.05 weight percent and about 0.2
weight percent. The invention allows the improvement of metal bond strength in metallizable
films. The invention encompasses both the resulting films with enhanced metal bond strength
and the process for producing such films. In the preferred embodiment, the proposed mini-random
copolymer is formed into a film layer used in place of a propylene homopolymer layer,
providing improved bonding properties over a simple polypropylene homopolymer, while
maintaining at acceptable levels the physical and optical characteristics of a film layer made
from a propylene homopolymer, such as stiffness.

IPC: H03F3/24
Filed: 1998-10-19
Abstract: Disclosed is a transmitter for switching and
transmitting signals of plural frequency bands. For
example, the signals of two frequency bands are switched and
transmitted. For the transmission in a first frequency band,
both of transistors 104, 105 are turned off, whereby a power
amplifying transistor 102 is matched by an input wide band
matching circuit 101 and an output main matching circuit 103,
so that the high efficiency linear amplification is
accomplished. For the transmission in a second frequency
band, the transistor 104 is turned on while the transistor
105 is turned off, whereby the power amplifying transistor
102 is matched by a capacitance 108 as well as the input wide
band matching circuit 101 and the output main matching
circuit 103, so that the high efficiency linear
amplification is accomplished. An external switch for
switching the matching circuits is thus unnecessary.

Abstract: A method for manufacturing ink jet recording heads

inorganic material in the form of ink flow path pattern
using the soluble first inorganic material on the
substrate having ink discharge pressure generating
elements formed thereon, forming a film of a second
inorganic material becoming ink flow walls on the film

thus arranged, it becomes passible to set the ink
discharge pressure generating elements and the ink
discharge openings (ports) of each head in extremely
high precision in a shorter distance with a good
reproducibility to record images in higher quality
without any deformation of the head due to the applied
heat, while providing a good resistance to ink and
erosion, as well as a higher dimensional precision and
reliability that may be affected otherwise by swelling

Abstract: The invention provides a pulse modulation
operation circuit comprising a current bus (3), a
plurality of switch current sources (2, 32) connected
parallel to each other and commonly connected to the
current bus for generating current pulses corresponding
to external input signals, charge conversion means (10,
11, 38) connected to the current bus for integrating
the current pulses and converting them into a charge,
and output means for converting the charge into a
binary digital signal and outputting the binary digital
signal. Each PWM signal (1) is input to a
corresponding one of the switch current sources (2),
which in turn generates a constant current for a period
corresponding to the width of each pulse of the signal,
to convert each signal pulse into a current pulse. The
thus-obtained current pulses are added on the common
current bus (3), thereby obtaining, by capacitive
integration, a total charge Q total  proportional to the
sum of the widths of the current pulses. To this end,
a reference charge counter circuit (6) has a function
for integration and a function for digitizing the total
charge Q total  in units of a reference charge Q std  in
real time. Further, an extra charge Q r  which occurs as
a quantization error is digitized in a time-series
manner by a charge-time converter circuit (7) to
improve the time resolution of calculation. Each
digitized value are weighed and added by digital
counter circuits (8) and (9), and output in the form of
a binary digital signal as the addition result of the
PWM signals.
