Abstract: 2.1 Containers which are subdivided by bottom plates into mutually separate compartments for magnetic tape cassettes are known. A slide which can be locked and can move the magnetic tape cassette out into a removable position by means of spring element is mounted on the bottom plate and has arranged on it resilient arresting devices, engaging in the two reel hubs of the magnetic tape cassette. 
<??>2.2 In order to ensure permanent functioning of the arresting devices, rocking levers with laterally attached lugs are provided as arresting devices, which lugs disengage the rocking lever from the reel hub when the slide is moved out, by running under noses arranged on the bottom plate, and engage the rocking lever in the reel hub when the slide is pushed in, by running onto ridges.

Abstract: A data coupler assembly (30) provides an improved electromagnet insert (52) having conductive wires (22A,22B) positioned within arcuate channels formed along with the electromagnet insert. Sealing means to position and seal the conductor wires to the assembly are included. Improved electromagnetic shielding by using metallic plating on the upper member of the coupler assembly provides effective, but lightweight, EMF/RFI protection. A rugged resilient spring means improves the formation of an electromagnetic core by biasing the electromagnet insert (52), and thereby biasing together each electromagnet pair to form electromagnet cores having a minimal air gap. A quick-action panel mounting means secures the coupler assembly to a panel (42), and improved aligning means precisely secures the upper member of the coupler assembly to the lower member.

IPC: G06F3/06
Filed: 1991-08-23
Abstract: A cached DASD controller is illustrated which is attached to a high speed serial channel, such as an optical fiber channel. The data rate of the serial channel is much greater than the data rate of a DASD connected to the controller. The serial channel has a relatively long propagation time such that synchronous operations between the host processor 10 and the DASD cannot be efficiently performed. Operation of a data transfer, whether read or write between the host processor 10 and the DASD is monitored. Whenever a copy of the track contents is in cache and the DASD reaches either an index mark with or a break point from a roll mode operation or certain write operations occur resulting in predetermined data being stored in cache, then a GOCACHE flag is set in a control portion of the controller. The device operations are then momentarily idled while cache to host processor operations are enabled.

Abstract: Field information for a predetermined number of fields produced by another field judgment circuit is stored in a first memory. The output of the field decision circuit which is indicative of the field information for the predetermined number of fields is stored in a second memory. The contents of the first memory are compared with those of the second memory. When the contents of the first memory disagree with the contents of the second memory for all of the predetermined number of fields, the field information is output as the field information from the field decision circuit.

Abstract: This invention relates to modified phase change ink compatible colorants which comprise a phase change ink soluble complex of (a) a tertiary alkyl primary amine and (b) dye chromophores, i.e., materials that absorb light in the visible wavelength region to produce color having at least one pendant acid functional group in the free acid form (not the salt of that acid). These modified colorants are extremely useful in producing phase change inks when combined with a phase change ink carrier, even though the unmodified dye chromophores have limited solubility in the phase change ink carrier. Thin films of uniform thickness of the subject phase change ink compositions which employ the modified phase change ink colorants exhibit a high degree of lightness and chroma. The primary amine-dye chromphore complexes are soluble in the phase change ink carrier and exhibit excellent thermal stability.

Abstract: The brake force generator has, for the purpose of generating the brake force, a pre-loaded spring (22, 23) which can be tensioned by means of a non-selflocking helical gear which can be driven by an electric motor (13). The helical gear comprises a first screw connection component (16) which can be driven in rotation by the electric motor (13) and which is loaded by the pre-loaded spring (22, 23). The first screw connection component (16) is screwed to a second screw connection component (24) which can be braked tight in an axially non-displaceable fashion by means of a controllable first brake (28). A third screw connection component (30) which is screwed via a thread of the same kind to the first screw connection component (16) is coupled in a rotatable but axially not-displaceable fashion to a force output element 34, can be braked tight by means of a second brake (36) and can be supported against a fixed stop (44) counter to the direction of the tensioning force. By releasing the first brake (28), a braking process can be enabled, by releasing the second brake (36) it can be disabled again and, subsequently, the pre-loaded spring (22, 23) can be tensioned again by means of the electric motor (13); the re-tensioning of the pre-loaded spring (22, 23) is also possible even during the braking process. Since only one brake (28 and 36, respectively) has to be opened to enable or disable a braking process, these processes can take place quickly and independently of the electric motor (13), thus no special emergency braking or emergency brake release devices are required. Since, in particular, the release time does not depend on the power of the electric motor (13), the electric motor (13) can be designed to be low in power and small, and the power supply for the electric motor (13) can also be correspondingly designed to be low in power. <IMAGE>

Abstract: An apparatus for controlling an air-fuel ratio in a lean burn internal combustion engine, such that three different air-fuel ratio zones are set, the three zones being an ultra lean zone with a low load, a medium lean zone with a medium load, and a non-lean zone with a high load. When the engine is under low load conditions, a map FLEANPM is selected to obtain an ultra lean air-fuel ratio based on detected intake pressure PM values and engine speed NE. When the engine is under medium load conditions, a map FLEANTA is selected to obtain a medium lean air-fuel ratio based on a detected throttle opening values TA and engine speed NE. When the engine is under high load, conditions the lean correction control is canceled, thereby obtaining a theoretical air-fuel ratio or an air-fuel ratio smaller than the theoretical air-fuel ratio, and when the engine remains at a point in the medium lean zone, the air-fuel ratio decreases gradually toward the theoretical air-fuel ratio as time elapses.
