Patent CA-2196007-A1 (CA)
Inventor: ISHIKAWA YOHEI
IPC: H01P5/02
Filed: 1997-01-27
Abstract: A variable-frequency resonator has a dielectric strip serving as a main line and a dielectric strip serving as a sub line. A dielectric resonator is disposed therebetween, and a diode board is disposed at an intermediate point of the dielectric strip serving as the sub line. The electrical length of the sub line is switched according to the electrically conductive/open state of the diode. With this switching, the resonant frequency of the dielectric resonator is changed. Therefore, a variable-frequency resonator having a high Q value, a variable-frequency oscillator having a high C/N ratio, and a variable-frequency filter having low loss are implemented.

Patent CA-2198161-A1 (CA)
Inventor: NISHIYAMA NAOKI
IPC: H03F3/08
Filed: 1997-02-21
Abstract: The photocurrent generated by a photodiode receiving light substantially flows through a feedback resistor when the incident light intensity is low.  As the incident light intensity increases, the source and drain of a FET connected in parallel to the feedback resistor establish a conducting state therebetween, whereby the photocurrent is divided into a current flowing through the feedback resistor and a current flowing through the FET connected in parallel to the feedback resistor.  Accordingly, transimpedance is equivalently lowered, while the feedback resistor is restrained from lowering the output potential.  When the incident light intensity is further increased, a gate bias current flows into the gate of an input-stage FET of an amplifier, whereby the photocurrent is divided into the current flowing through the feedback resistor, the current flowing through the FET connected in parallel to the feedback resistor, and the gate bias current.  Accordingly, the preamplifier can operate even under a larger optical input.  Thus realized is a novel configuration of a preamplifier for optical communication, from which a stable operation is expected even when the power supply voltage is lowered and which can operate at a single power source voltage as well.

Inventor: RODIER SYLVAIN
IPC: H05K13/02
Filed: 1997-04-15
Abstract: A fully automatic device is provided for handling components-containing tubes and for feeding the components contained in these tubes into the input rail or "accumulator" of the loading area of a component processing equipment. Another fully automatic device which is very similar in structure to the above device is also provided for recovering the components from the output rail of the unloading area of the component processing equipment, and reinserting such components into their tubes. Both of these devices have a column holder mounted on a frame for receiving and holding a column of tubes stacked one above the other. A rotatable barrel having a conical shape and a horizontal axis supports a set of tube catching assemblies. A motor rotates the barrel to position successively each of the tube catching assemblies horizontally just in front of the bottom end of the column holder to pick up oneof the tubes of the column holder, which is pushed forwards by a pusher mechanism, and then to move the catching assembly and tube held by the same up to a vertical, inclined position where the tube extend in line with the loading or unloading area of the equipment and can be emptied or filled up with components. An ejecting system pushes the emptied or filled tubes out of the barrel and into a chute. Such devices are very efficient and may easily handle up to 45,000 electronic components per hour.

Patent CA-2207226-A1 (CA)
Title: Optical fiber grating and method of manufacturing the same
Inventor: ITO MASUMI
IPC: G02B6/24
Filed: 1997-06-09
Abstract: This invention relates to an optical fiber grating and a method of manufacturing the same. According to the method, a hydrogen doping process is performed before ultraviolet irradiation in order to obtain a sufficient photoinduced refractive index change. In particular, a target for the hydrogen doping process of the method is characterized by a coated fiber obtained by covering the outer surface of the bared fiber having a core region and a cladding region with the resin.      After the coated fiber is exposed in a hydrogen atmosphere in a predetermined pressurized state for a predetermined period of time, the resin is partially removed. An ultraviolet ray is irradiated on the predetermined area of the bared fiber from which the resin is removed, thereby forming a reflection grating in the core region. The method is also characterized in that the pressure of the hydrogen atmosphere is reduced from the pressurized state while adjusting the pressure reducing rate. Degradation of the bared fiber surface can be prevented, and generation of bubbles or the like between the bared fiber and the resin coating can also be prevented, thereby obtaining an optical fiber grating with high reliability.

Title: A novel form of dipeptidylpeptidase iv (cd26) found in human serum, antibodies thereto, and uses therefor
Inventor: MORIMOTO CHIKAO
IPC: C12P21/08
Filed: 1996-06-03
Abstract: A circulating, soluble form of DPPIV/CD26 isolated from human serum is disclosed. The serum form shares similar enzymatic and antigenic properties with the ubiquitous membrane form. However, in several biochemical aspects there are distinct differences. In particular, the circulating serum form has a molecular weight of 175 kDa (in contrast to the 105 kDa molecular weight of the membrane form), and it does not bind Adenosine Deaminase Type-1. Nevertheless, the circulating form expresses functional dipeptidylpeptidase IV activity and retains the ability to costimulate the T lymphocyte response to recall antigen. Circulating DPPIV has been determined to be the soluble form of a 175 kDa DPPIVCD26-related molecule rapidly expressed on the surface of activated T cells, prior to the expression of 105 kDa CD26. Although 105 kDa membrane type CD26 may be found in the serum in small amounts, the majority of serum DPPIV activity is provided by a novel peptidase structurally distinct from 105 kDa CD26/DPPIV. Polyclonal and monoclonal antibodies capable of distinguishing the 175 kDa form from the 105 kDa form are also disclosed.

Filed: 1998-01-22
Abstract: A large, mechanically agitated pump box is used between a mixer, for mixing oil sand and water to produce a slurry, and a pipeline for conveying the slurry to a processing facility. Prior to the aqueous slurry being discharged into the pump box from the mixer, it is screened to reject large solids. The oversize is directed to an impactor where it is comminuted and the comminuted product is screened again prior to being discharged into the pump box. The pump box is designed to increase the residence time of the slurry in the pump box and to separate the slurry into two phases, the suspended slurry and the larger lumps that cannot be suspended. The larger lumps that settle in the pump box are recycled to the impactor for comminution.
