Patent CA-2088047-A1 (CA)
Inventor: INOUE MATSUHISA
IPC: C12Q1/34
Filed: 1991-12-18
Abstract: A cephalosporinase testing agent comprising a cephalosporin antibiotic such as cephaloridin, a penicillinase inhibitor in an amount of 20 wt% or less based on the antibiotic, and a pH indicator such as bromocresol purple. A cephalosporinase producing bacterium can be judged by smearing a sample containing a test bacterium on the testing agent and observing the color tone change. According to this agent, a cephalosporinase-active penicillinase producing bacterium is judged cephalosporinase-negative by the action of a penicillinase inhibitor such as clavulanic acid. Therefore only a cephalosporinase producing bacterium is judged cephalosporinase-positive. Thus this agent is useful since it is free from misjudgment.

Abstract: A surface acoustic wave device has a package and a surface acoustic wave element mounted therein face down.          The package includes a side wall comprising linear inner side surfaces close to respective outer side surfaces of the surface acoustic wave element and recesses defined where the inner side surfaces of the side wall intersect at respective inner corners. When the surface acoustic wave element is inserted into the side wall along the inner side surfaces thereof, the corners of the surface acoustic wave element do not engage the side wall because of the recesses.          Therefore, the outer side surfaces of the surface acoustic wave element may be positioned very closely to the inner side surfaces of the side wall. The surface acoustic wave device may be reduced in size, and the surface acoustic wave element may have input and output electrode pads and ground pads positioned highly accurately with respect to electrode pads on the bottom plate of the package.

IPC: H04J13/16
Filed: 1992-04-03
Abstract: A wireless communication system including a repeated pattern of cells (203) in which base station transmitters (204) and user station transmitters (202) for each all may be assigned a spread-spectrum code for modulating radio signal communication in that cell. Radio signals used in that cell are spread across a bandwidth sufficiently wide that both base station re-ceivers and user station receivers in an adjacent cell may distinguish communication which originates in one cell from another. Adjacent cells may use distin-guishable frequencies and distinguishable codes, but it is sufficient if adjacent cells use distinguishable fre-quencies and identical codes. A repeated pattern of cells allows the codes each to be reused in a plurality of cells.

Title: Electronic Module of Extra-Thin Construction
Inventor: NICKLAUS KARL
IPC: H01L21/56
Filed: 1993-11-23
Abstract: In the electronic module (M) of extra-thin construction disclosed, it is the principal object to substantially reduce the tendency to fracture of the module's semiconductor chip (1) embedded in the plastic casing (10) of the module (M), notwith-standing the extremely small thickness of the casing. The chip is fitted on the chip pad (22) of a system support (20) formed by a thin metal strip, commonly known as a lead frame. The chip (1) may partly overlap the external contacts (21) of the module that lie on one of the flat sides of the module's plastic casing (10). Slits (23) in the system support, which form the boundaries of the chip pad (22) and are inevitable lines of weakness in the thin metal strip, are situated at an oblique angle relative to the edges of the square or rectangular chip (1), preferably at about 45°; hence the slits extend also at an oblique angle to possible fracture lines within the monocrystalline structure of the material used in chip manufacture, because said fracture lines are parallel to the chip's edges. Other slits (24) in the metal strip, which extend from said boundary slits (23), should preferably also be at an angle relative to the edges of the chip. Further characteristics disclosed relate to the  mechanical bond between parts of the system support (20) and the module casing (10), and the bonding of the entire module (M) to the surrounding plastic material when it is moulded into a supporting body or medium, for example in the manufacture of chip cards.

Title: Digitally controlled fractional frequency synthesizer
Inventor: RIEDER KLAUS-HARTWIG
IPC: H03L7/197
Filed: 1994-06-08
Abstract: The circuit arrangement of the invention presents an oscillator, whose frequency can be linearly varied within a wide control range, without affecting the oscillator's stability.  The frequency of a fixed frequency generator (1) is divided to the desired frequency by a frequency divider (2), whose divider ratio can be varied in very small steps, and the resulting jitter is filtered out by a very simple phase control circuit (3).  Improved short-term stability and holdover performance are also achieved.  The oscillator can be universally used as clock generator in all digital circuit arrangements.
