Granted: 2002-07-02
Abstract: A blood analyzer system incorporates means for handling and transporting sample blood through at least one blood analyzer and an automatic blood smear generator under the control of a programmable controller. Blood samples are stored in sample containers having identifiers for the sample blood that they contain. These sample containers are transported through the system in protective racks that permit the reading of the identifiers. The results of analysis by one or more blood analyzers in the system determines the need for performing or omitting subsequent operations on a particular sample blood. When a smeared blood sample is to be made, the controller assures that the smear thickness is consistent with other samples regardless of the thickness or viscosity of the sample blood. If the system fails to make a required smeared blood sample, a detector sounds an alarm, warning of a system failure.

Title: Inscribed meshing planetary gear construction
Inventor: TAKAHASHI ATSUSHI
IPC: F16H1/32
Filed: 1992-08-12
Granted: 1999-02-09
Abstract: An  inscribed  meshing  speed  increasing  and reduction gear construction in which external teeth (for example, a1 and a2, b1 and b2, and c1 and c2) cut at the same position during processing are not simultaneously meshed with (outer pins 111 of) internal-tooth gear during operation in order to improve the accuracy after completion of assembling even if the gear is cut by a machine of similar processing accuracy.  Thereby, (although it seems to be contrary to a conventional idea that said external teeth cut at the same position should be simultaneously meshed with the internal-tooth gear), the actual accuracy after completion of assembling can be improved.   In this case, when both the number of teeth (24 in Fig.  1) of external tooth gears 105a and 105b, and a difference in the number of teeth (4 in Fig. 4) between the external-tooth gear and (outer pins 111) internal-tooth gear, are set to integer times of the number (2 in Fig. 1) of the external-tooth gears, the external teeth of the external-tooth gears and various holes formed in the external-teeth can be all simultaneously  (by  one  setting)  cut,  and  remarkably improving  the  accuracy  of  the  positional  relationship between the external teeth and various holes.

Granted: 2002-01-15
Abstract: An efficient buffering mechanism for access and retrieval of stored high bandwidth data and sufficient storage is disclosed. In a typical operating system, a channel containing only a limited buffer between the input devices and the running applications is provided by the operating system. This invention provides a parallel channel of a higher bandwidth with a far superior buffering capability that complements that of the operating system.     When an input event from an input device with a high bandwidth is received by the system, messages are sent to both the operating system channel and the high bandwidth channel in a compatible format for each channel. The message sent to the operating system channel generally contains only limited data which may have to be translated from the actual input data to be acceptable to the operating system. The message sent to the high bandwidth channel contains the full spectrum of data generated by the input device, The buffer in the operating system channel also has the property of discarding data if the application does not retrieve them quickly enough during periods of high CPU utilization. The buffer in the high bandwidth channel keeps all data for up to 1000 input events, or whatever is deemed sufficient for the computer system, regardless of CPU usage.      In response to the interception of a translated event in the operating system queue for one of the applications in the system, the method of the present invention will check to see if there are any events in the high bandwidth buffer.     If there are, the system dequeues all the events to send them to the intended application. Various flags are set if task preemption is detected by the system upon examination of the events in the high bandwidth queue. Further, certain events may be sent asynchronously to the high bandwidth channel alone from various input devices; the system is prompted by a false "mouse" message in the operating system queue to cause the system to examine the high bandwidth buffer for the true input event.
