Title: Device for reporting start of preceding vehicle
Inventor: MATSUMOTO KAZUHISA
IPC: G08G1/16
Filed: 2000-01-25
Abstract: PROBLEM TO BE SOLVED: To give proper report on the start of a preceding vehicle. SOLUTION: A reporting vehicular gap Lk corresponding to a relative velocity arithmetic value Vr is set and when the detected value of the vehicular gap exceeds the distance Lk when the detected value of a self-vehicle speed is 0, report that a preceding vehicle has started is given. Thus, the report on the start of the preceding vehicle is given properly without delay whichever the preceding vehicle starts suddenly or gently or though the preceding vehicle repeats starting and stopping in traffic jam.

Title: Heat sealer for wrapping material
Inventor: SAKAMOTO AKIRA
IPC: B65B9/00
Filed: 2000-02-14
Abstract: PROBLEM TO BE SOLVED: To improve a seal finishing by preventing bubbles from remaining on a sealed surface in heat-sealing a wrapping material. SOLUTION: A seal belt 12 is traveled synchronously with feeding of the wrapping material, and sealing heat is applied while contact-bonding a seam S of the wrapping material with a heater block in slide contact with an inner peripheral face of the belt 12. Since a heating surface of the heater block is formed to broaden along a traveling direction of the wrapping material in its sealing section, during a process that the material is sealed, a sealed region M which is heat-welded gradually increases to the maximum width W. Since air existing between the seams S is expelled to both sides of the sealed region M during such a sealing process, no bubbles remain in a sealed face after sealing is completed.

Title: Method and circuit for improving voltage regulator load transient response and minimizing output capacitor size
Inventor: REDL RICHARD
IPC: G05F1/565
Filed: 2000-02-14
Abstract: PROBLEM TO BE SOLVED: To minimize the capacitor size by maintaining the regulator's output voltage within specified boundaries for large bi-directional step change in load current. SOLUTION: A current sensor 64 at a controllable power stage 50 generates an output signal which varies along with the output current from the power stage 50. A current controller 66 receives the output signal thus generated along with the output 62 from a voltage error amplifier 59 to produce an output 67. In response to the output 67 from the current controller 66, a power circuit 68 generates an output voltage Vout. The output capacitor 56 of the power circuit 68, i.e., a regulator, maintains the output voltage within a boundary specified for the bi-directional step change in load current. Consequently, the capacitor size is minimized and the power circuit 68 can be compensated.
