Patent EP-0383195-A2 (EP)
Inventor: TAKAHASHI TOSHIYASU
IPC: G11C11/4096
Filed: 1990-02-08
Abstract: A DRAM controller comprises an address output con­troller (30) for transferring an address-designating signal to a dynamic RAM, a data output controller (32, 34, 36) for transferring data to be written into and read-out from that memory region of the dynamic RAM which is designated by the address-designating signal, and a control circuit responsive to a mode-designating signal for generating various control signals corre­sponding to an access mode of the dynamic RAM designated by the mode-designating signal, and supplying the con­trol signals to the dynamic RAM, address output control­ler (30), and data output controller (32, 34, 36) in a predetermined sequence. In the DRAM controller, the con­trol circuit includes a signal-generating unit (50B) for generating the control signals in a specific access mode which requires an access time longer than the machine cycle of a processor for generating the address-­designating signal, the data to be written, and the mode-designating signal, and for delaying the generating of the control signals every time the designation of the specific access mode is repeated.

Abstract: The invention relates to a sensor and a method for measuring the relative speed of a flowing medium. 
<??>In the case of measurement by means of a conventional Prandtl's Pitot tube, the problem exists that a stationary shock wave (9) is built up in the supersonic region as a zone of unsteady pressure behind the front end (2) and migrates to the rear as the speed increases. For this reason, pressure measuring points (5) must be located far behind the front end (2), as a result of which the overall length of the sensor becomes undesirably large. 
<??>Said problem is solved when the sensor body has a sensor head (1a), the largest diameter of which is greater than the outside diameter of the sensor shaft (1b), and at least one pressure measuring point (5) on the rear of the sensor head (1a) opens outwards directly behind a distinct shoulder, doing so from the latter or from the sensor shaft (1b). 
<??>This results, moreover, in an increase in the measurement reliability even for relatively large angles between the flow and the longitudinal axis of the sensor, and the same applies to the measurement sensitivity. 
<??>The preferred field of application is aviation technology.

Title: Structure of system for automatically controlling vehicle speed to desired cruise speed
Inventor: SENOO TETSUO
IPC: B60K31/00
Filed: 1990-08-31
Abstract: A structure of a system for automatically controlling a vehicle speed to a desired cruise speed is disclosed in which, when a signal generated by a cancel switch (19) provided for halting a control operation of the system, is generated by a turning on of the cancel switch (19), a voltage applying portion, intervened between the cancel switch (19) and each signal lines (5,7) connected between one of set/coast switch (1) and acceleration/resume switch (3) and a corresponding input end (IN₁,IN₂) of a control circuit (11), generates a voltage whose level is different from that generated when either set/coast (1) or acceleration/resume switch (3) is operated, the voltage being supplied to each of the signal lines (5,7). A signal generating portion (27) provides a third signal in response to the applied voltage from the voltage applying portion to another input end (IN₃) of the control circuit (11). Thus, the cancel switch signal can be distinguised and identified from the other switch signals derived from the set/coast (1) and acceleration/resume switches (3) even if one or all of the signal lines (5,7) has failed.

Abstract: The invention relates to a method of monitoring a process of growing a thin film of silicon di­oxide doped with phosphorus, comprising growing a sample thin film by the growing process to be monitored on the surface of a substrate; and determining the relative phosphorus concentra­tion of the thin film. In the present invention, to enable simpler determination of phosphorus concentration more rapidly and more accurately than previously, the sample thin film is grown on a substrate made of a material containing no silicon, whereby it is possible to measure the intensity of the fluorescent radiation of both phosphorus and silicon separately by an X-ray fluorescence method and to determine the propor­tional amount of phosphorus in the thin film as the ratio of the measured intensities. The method is calibrated by preparing standard films having equal phosphorus/silicon ratios on the same substrate material.

Abstract: A test driver (104) for connecting a controlling computer (106) to an IC chip (102) having a standard test access port (TAP) is both hardware and software efficient. The last stage (226) of a wrap-around or circulating control register (230) is connected to a further bit storage stage (228) and serves to drive a test mode select (TMS) pin of the TAP. The last stage (226) is fed back to the first stage (206). As a result of the control register configuration, its original contents are automatically restored after each shift cycle, thus abrogating the need to reload it if the same control pattern is again needed, and abrogating the need to maintain (via software) the correct value on the TMS pin in between shifting sequences of the control register. Proper shift times in a data register of the test driver are achieved by replicating the IC chip TAP controller state machine.

Abstract: A neutron detector is formed from a layer of polycrystalline diamond (12, 24, 40) which is deposited by a chemical vapour deposition process. The diamond material contains  10 B as a dopant, in a concentration of 1 000 ppm or less. In one embodiment, the layer of diamond material is deposited on a supporting substrate (10). Advantageously, the substrate itself may comprise a layer of diamond material. In another embodiment, the substrate comprises a layer of conductive or semiconductive material (22). The diamond material is deposited on top of the substrate, with at least two regions in contact with the semiconductive material. A central portion of the semiconductive material is etched away, and electrical contacts (26, 28) are applied to the remaining portions (22.1, 22.2) of the semiconductive substrate. An advantage of the neutron detector of the invention is that the diamond layer is very thin, less than 50  f Lm thick, so that the sensitivity of the detector to other radiation, particularly y radiation, is reduced.
