Title: A two-wheel to four-wheel drive shifting device
Inventor: YAMADA HIROAKI
IPC: B60K17/26
Filed: 1997-10-15
Abstract: A two/four wheel drive shifting device capable of detecting a success or failure in shifting of a free wheel mechanism to a locked state without encumbering components for detecting free and locked states of the free wheel mechanism being directly disposed in the free wheel mechanism. The two/four wheel drive shifting device has a two/four wheel drive shifting mechanism disposed in a transfer mechanism, a device for detecting shifting between two wheel and four wheel drive, an indicator for showing the shifting, an actuator for shifting a free wheel mechanism which is disposed in either a front wheel or a rear wheel differential mechanism, a pressure pump for supplying working pressure, a pressure detector for detecting the working pressure, and a control to actuate the pressure pump to supply working pressure to the actuator when shifting to four wheel drive is successful. The control also deactivates the pressure pump and actuates the indicator in order to show a successful shifting to four wheel drive when the working pressure has achieved a predetermined pressure.

Title: Method and apparatus for time division duplex pilot signal generation
Inventor: GILHOUSEN KLEIN S
IPC: H04W36/14
Filed: 1996-08-07
Abstract: A method and apparatus for providing a reliable means to perform handoff from a code division multiple access (CDMA) system using a pilot signal to an alternative access technique system. Simple pilot box circuitry (350) is added to a set of border base stations (C2A-C2R). The border base stations are base stations (C2A-C2R) which operate only in the alternative access technique and which have coverage areas which are contiguous with coverage areas of CDMA operation base stations (C1H-C1S). The mobile unit (10) monitors for the pilot signal from the border base stations (C2A-C2R) in the same manner as it monitors for pilot signals from the CDMA operation base stations (C1A-C1S). When the mobile unit (10) detects the pilot signal corresponding to a border base station (C2A-C2R), it notifies a system controller (202) in accordance with standard operation. The system controller (202) is aware that the pilot signal corresponds to a border base station and thus triggers a hard handoff process to the alternative access technique system in response thereto. The border base stations (C2A-C2R) use a time division duplex technique to monitor a pilot and synchronization sequence from a neighboring one of the CDMA operation base stations to obtain an estimate of absolute system time.

Abstract: A recombinant, thermostable DNA polymerase is provided herein. Such polymerase comprises the amino acid sequence LeuSerXaaXaaLeuXaaXaaProXaaXaaGlu (SEQ ID  NO: 1), wherein "Xaa" at positions 3, 6, 9, and 10 of the sequence are any amino acid residue, "Xaa" at position 4 in the sequence is a polar amino acid, or a positively-charged amino acid and "Xaa" at position 7 of the sequence is Val or Ile. The recombinant, thermostable DNA polymerase has a level of discrimination against incorporation of nucleotides which are labeled with fluorescein family dyes which is reduced in comparison to the native form of the polymerase. Such modified recombinant, thermostable DNA polymerases have enhanced efficiency for incorporating unconventional nucleotides, e.g., those labeled with fluorescein family dyes. Such modified recombinant, thermostable DNA polymerases can be prepared by methods of recombinant DNA technology. Such recombinant, thermostable DNA polymerases are advantageous in many in vitro DNA synthesis applications, e.g., DNA sequencing, synthesis of labeled DNA or the production of labeled primer extension products. Such recombinant, thermostable DNA polymerases are particularly useful in chain termination nucleic acid sequencing methods. Nucleic acids encoding the recombinant, thermostable DNA polymerases, as well as vectors and host cells each including them are also provided. Kits comprising the recombinant, thermostable DNA polymerases are also provided. The recombinant, thermostable DNA polymerases and methods provided herein provide significant cost and efficiency advantages for DNA sequencing.

Title: Magnetic menu board
Inventor: DUGUAY ELOI
IPC: G09F7/04
Filed: 1998-04-09
Abstract: A menu board system comprising a support structure, made of magnetically attractable material, and various strips indicating, for instance, products sold and magnetic elements indicating prices at which products are sold. Once all the elements and strips are in place on the support structure, the front surface of the menu board seems flat and continuous as all pieces are cut to fit perfectly in an edge-to-edge pattern. The price elements are easily removed by simply pressing an element's bottom portion allowing the top portion to lift off the support structure. The ease of removal is caused by a magnet fixed only to the top portion of the back surface of the price element. The bottom edge of the magnet acts as a fulcrum point and the back surface of the element left uncovered is simply pushed into the support structure, permitting the top portion of the element to be grasped.

Title: Fluid pump control apparatus and method
Inventor: FUKUMA TAKAO
IPC: F02M41/14
Filed: 1999-01-18
Abstract: An apparatus and a method control an amount of pressurized fluid to be pumped by a high-pressure fluid pump to a common rail, by using a control circuit (ECU), in order to improve the controllability of the fluid pumping amount of the fluid pump. The ECU sets a base fluid pumping amount based on a target value of pressure in the common rail and an amount of fluid ejected from the common rail. The ECU also calculates a fluid pumping amount required to cause the actual pressure of the common rail to follow a change of a target pressure of the common rail on a basis of an amount of change of the target pressure. The ECU sets the sum of the basic fluid pumping amount, the required fluid pumping amount and a earned-over amount of fluid, as a set value of the fluid pumping amount. If the set value of the fluid pumping amount exceeds a predetermined capacity of the fluid pump, the ECU sets a difference between the set value of the fluid pumping amount and the predetermined capacity as the carried-over amount of fluid that is carried over to a next setting of fluid pumping amount, thereby reflecting the difference therebetween in a next set value of the fluid pumping amount.
