Abstract: A cationic resin containing blocked isocyanate groups which is suitable for use in electrodeposition is disclosed. The cationic resin is derived from an epoxy resin and contains in the resin molecule cationic salt groups, active hydrogen groups and blocked isocyanate groups. The blocked isocyanate groups are incorporated into the resin molecule by reacting the epoxy resin with a compound selected from the class consisting of mercapto compounds and acid group-containing compounds where the compounds also contain blocked isocyanate groups. The resin can be formulated into an electrocoating composition which is free of lead and yet provides outstanding corrosion resistance when electrodeposited over steel substrates. The outstanding corrosion resistance can be attained when the substrate has not been given a chrome rinse which is conventional in pretreating the steel substrate before electrodeposition.

Abstract: Magnetic tape cassettes are typically stored in a case (1) which includes a cover (2) having a pocket (4), and a casing (8) portion. To identify the contents recorded on the magnetic tape, an index card (11) is disposed between the magnetic tape cassette and case. When the index card is inserted into the case at high speeds during manufacturing thereof, air is trapped between the case and the index card causing inefficient production and damage, such as bending, to the index card. To remove air, air passage holes (10) are provided within a side wall of the pocket of the case or within the bent portion of the index card.

Abstract: A cooling device for optical and/or electronic elements, for example diode lasers, and/or other test devices (elements) has a stock container for a cryogenic liquid which is fed to a vaporising chamber in which it completely evaporates, thereby extracting heat from the element. In its lower section, the vaporising chamber has an inlet opening through which the cryogenic liquid enters the vaporising chamber and in its upper section it has an outlet opening through which the vapour escapes via a throttle into the cryogenic liquid stock container. Preferably, the upper end of the vaporising chamber is lower than the lowest level of the cryogenic liquid stock, and the cryogenic liquid is supplied and the vapour removed by means of pipelines which can be shaped in any desired way. The element to be cooled is connected in a heat-conducting manner to a heat-conducting element which has a low thermal resistance and which projects into the vaporising chamber in such a way that the cryogenic liquid in the vaporising chamber wets the heat-conducting element. In the cryogenic liquid stock container, the heat-conducting element is thermally insulated.

Abstract: Two rollers (44,55) with lobes for feeding a sheet are disposed below the plane feed surface (22). The two rollers are rotatable on axes perpendicular to one another and move the sheet or the document to be printed in a direction perpendicular and parallel, respectively, to the printing direction (20) of the head (14) to align the sheet against inverted V elements (80) movable parallel to the printing direction, and against lateral guide (158) perpendicular to the printing direction. Suitable optical sensors (155,156) detect possible misalignment of the sheet and cause further rotation of the rollers to complete the alignment of the sheet against the guides.

Abstract: A wavelength-tunable semiconductor laser of distributed feedback (DFB) type wherein a diffraction grating having periodic corrugations along the direction of travel of light is formed on an active layer (3) or at least one of the layers (2) adjacent thereto. An electrode on one side is separated into four or more electrodes (12 to 16) in the direction of the cavity of the laser. Nonadjoining ones of these electrodes are electrically connected to form two electrode groups (12;14;16 and 13;15). The total length of first regions (7,9,11) corresponding to one of the two electrode groups (12;14;16) is larger than the total length of the other regions (8,10) corresponding to the other electrode group (13;15). The refractive indexes of the first regions are changed through current injection change to its electrode group to vary the lasing wavelength and the gain of the second regions is controlled through current injection to its electrode group, thereby generating output light of a constant output power and a variable single wavelength.

Abstract: The problem of noise enhancement is eliminated in communications systems by predistorting the amplitude of the transmitted information signal in a manner which compensates for the amplitude distortion introduced in a portion of the communications channel. In the disclosed embodiments, the communications system includes two signal transceivers which communicate with one another through a communications channel. The communications channel includes two-wire subscriber loops adjacent to each signal transceiver with a four-wire transmission path disposed between the subscriber loops. Each transceiver transmits an information signal which, depending on the system noise characteristics, is predistorted to compensate for all or a portion of the amplitude distortion introduced in a subscriber loop adjacent to that signal transceiver. The predistortion necessary to provide such compensation is determined at each transceiver in response to received signals at that transceiver.

Abstract: A service network has several computer systems connected together. A computer system can either be a "Service Requestor" (SR) (110), a "Service Provider" (SP) (150), or a hybrid of the two, a "Service Provider/Requestor" (SP/R) (140). The status of the resolution of the problem can be monitored by the computer systems of the support network. Each SR, SP/R, and SP contains a problem log to track the status of each problem. Problems can have a status of OPEN, READY, PREPARED, SENT, ANSWERED, FIXED, VERIFIED, and CLOSED. The problem log present in each computer system makes it possible for status of the network to be easily monitored. The monitoring activity can be user queried via a series of screens or by graphically displaying a pictorial representation of the network or a portion of the network on a console associated with a computer system of the network. A system can also send an advisory to other computer systems to notify them of problems for which they do not have support responsibility.

Abstract: A localized subemitter collector region (SEC) is formed in the buried collector layer (BCL) underlying the emitter region (E) and active base region layer (ABL) of a bipolar transistor structure (12). The subemitter collector region (SEC) is implanted with relatively fast diffusing N type atoms distributed in a retrograde concentration upward from the buried collector layer (BCL) into the epitaxial layer (EPI) and preferably up to the active base region layer (ABL) below the emitter region (E). Preferably, phosphorous atoms are implanted in the subemitter collector region to a relatively high N+ concentration. The subemitter collector region (SEC) occupies a horizontal cross section area approximately 10% to 20% of the horizontal cross section area of the buried collector layer. The bipolar NPN transistor structure (12) is incorporated in a BICMOS integrated circuit. In the BICMOS IC fabrication process the NWELL definition and implant mask for the CMOS transistor structure is also a subemitter collector definition and implant mask providing an SEC definition opening for the bipolar transistor structure.
