IPC: H01R12/79
Filed: 1994-09-29
Abstract: PURPOSE: To connect contactors without causing a wiping phenomenon by bending the contactors in the inside of a housing by a load. CONSTITUTION: A contact 11 is installed in the inside of a housing 13 and held at a part under a point P by the lowest part of the housing 13. The rest part is projected out of an upper part chamber 17. The chamber 17 is extended while practically covering the whole length of the upper part. Parts 19, 21 are both closed as to push a lower part of the contact 11. An electric connector comprising at least one electric contactor installed in the inside in the above mentioned manner is claimed. The connector can previously apply a load as a result of a pushing function at a preset position along the contactor as to effectively have a contact with each conductor of respectively projected tip end parts of the contactor by the connection without causing a practical wiping.  Moreover, the connector can be kept in static state in relation to relevant circuit parts used for a housing or the conductor can be kept in static state instead and the connector can reliably be moved to there.

Filed: 1988-09-21
Abstract: PURPOSE:To reduce the extent of mass in an overflow valve by setting up a pressure control chamber eccentically at the side of a sliding hole to the axis of a piezoelectric element, and shortening axial length of the overflow valve, in a device where fuel injection is performed when the overflow valve is closed by a rise of working fluid pressure in the pressure control chamber. CONSTITUTION:When an electric charge is impressed on a piezoelectric element 77 and extended, a piston 73 goes down whereby fuel pressure in a variable- displacement chamber 78 and a pressure control chamber 66 goes up so suddenly, and an overflow valve 31 moves to the left via a rod 60, thus this overflow valve is closed. Then, fuel pressure in a fuel pressurizing chamber 15 goes up by the down motion of a plunger, and when the fuel pressure exceeds the specified one, a needle 7 is opened so that fuel is sprayed out of a nozzle 3. In a suchlike fuel injection valve, an axis M of the piezoelectric element 77 is set nearly at a right angle with reference to a common axis of a sliding hole 30 and the pressure control chamber 66, and this pressure control chamber 66 is set up on an axis N decentered to the side of the sliding hole 30 as far as (e) to the axis M of the piezoelectric element 77.

Abstract: PURPOSE:To exactly detect track moving velocity even at any position on a disk by storing the track cross angle of a beam spot in advance even when this angle is different, and correcting it. CONSTITUTION:For a tracking error signal obtained from the photodetector of an optical head 1, a track cross signal detection part 2 detects a pulse corresponding to track crossing. This signal is inputted to a current track counter 3. On the other hand, the pulse signal from the detection part 2 is transmitted to a velocity detection part 8, and current moving velocity is detected. In this case, while receiving the value of the current track counter 3, a correction reference part 11 calculates the track crossing angle or track of the beam spot, and a detected velocity correction part 12 corrects the detected velocity. The corrected detection velocity is transmitted to a comparison part 9 together with the output signal of a command velocity detection part 7 and transmitted to a swing arm actuator driving circuit 13 as a drive signal.

Title: Method and device for detecting speed of fluid
Inventor: WATANABE YOSHIJIROU
IPC: G01P5/00
Filed: 1993-08-30
Abstract: PURPOSE:To easily detect the flow velocity of a fluid based on the frequency of sounds corresponding to the flow velocity of the fluid by generating the sounds by periodically rotating the fluid. CONSTITUTION:When a fluid is sucked in a supplying passage 2a from an inlet 2b, the fluid spouts into a cylindrical body 1 in a direction A from an outlet 2a through an opened window section 1a at a speed higher than the flowing-in speed, since the cross-sectional area of the passage 2a becomes gradually smaller as going toward the outlet 2c. Then the fluid starts to rotate along the internal surface 13 of the body 1 and, when the fluid reaches a point D, the internal pressure of the body 1 rises, because the fluid spouting in the direction A obstructs the flow passage of the rotating fluid. When the internal pressure becomes higher than a prescribed value, however, the flowing direction of the spouting fluid is abruptly changed to another direction E and the fluid rotating in the body 1 is discharged in a direction F. As a result, the internal pressure of the body 1 abruptly decreases and the fluid from the outlet 2c spouts into the body 1 and raises the internal pressure. When such operations are repeated, sounds are produced and the flow velocity of the fluid is measured based on the frequency of the sounds.
