Patent JP-S57108305-A (JP)
Title: Draft gate
Inventor: UEDA YUKIHIKO
IPC: E02B7/52
Filed: 1980-12-24
Abstract: PURPOSE: To lessen the intrinsic vibration frequency of a gate to be used in a pumped storage tye power station, etc., as well as to absorb vibrational extenal force acting on the gate by stopping the gate by the pressure of an oil-pressure cylinder serving as a stopper during the ordinary period.   
     CONSTITUTION: During the ordinary period, a gate 14 is stopped by the pressure of an oil-pressure cylinder 16, whereby the intrinsic vibration frequency of the gate 14 is lessened and vibrational external force, e.g., high-frequency pulsative pressure, acting on the gate is absorbed. Whereupon, a buffer device 17 is in unloaded state, and the screen of a buffer bolt 19 is protected from breakage by vibration because it follows the piston 16' of the oil-pressure cylinder 16. Air inside a diversion channel 4 soon goes upwards into a bonnet 9 along the slope 15 of lip when lifting up the gate 14 by the oil-pressure cylinder 16, whereby preventing the vibration of the gate 14. Also, when water passes through the lower part of the gate 14 when tracting the gate 14, no swirl flow occurs and no vibration takes place in the gate 14 because the lip of the gate is inclined.

Title: Interference calculating method
Inventor: SATO TOSHIAKI
IPC: G06F17/50
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To stably calculate interference between two three-dimensional shapes. SOLUTION: Two pieces of three-dimensional shape data whose interference is to be calculated are referred to in a three-dimensional shape database 10 (S1) and a rectangular parallelepiped (or sphere) covering line and plane data of two shapes is generated (S2) and saved in an interference candidate database 20 (S3). The interference of the saved rectangular parallelepiped is checked and a line or plane as an interference candidate is marked (S4). When the marked line or plane has an error larger than the permissible error of interference calculation, the error is corrected to be below the permissible error or when the length or area of a line or plane present at a place as the candidate for interference is smaller than a permissible error, the line or plane is removed (S5). The obtained corrected shape is saved in the three-dimensional shape database 10 (S6) and the correction result is used to perform interference calculation (S7).

Abstract: PURPOSE:To eliminate the device phase deciding function and to simplify the structure of each controller, by giving the priority to plural controlles and stopping the transmisson of the control signals of the controllers having lower priority with the control signals of the controllers of higher priority. CONSTITUTION:The priority is given in order of controllers 103, 102 and 101.  The output switches 201 and 202 of controllers 101 and 102 are controlled with  the output signal 108 of the controller 103, and the output signal 107 controls the switch 201.

Title: Driving power control device for vehicle
Inventor: TAMURA MINORU
IPC: B60W10/10
Filed: 1986-08-05
Abstract: PURPOSE:To promote the compatibility of both the earlier focusing of a driving wheel slip and the prevention of an excessive fall-in of driving power, by obtaining a target throttle opening value by an accelerator control amount and a control characteristic map in accordance with a slip rate. CONSTITUTION:A driving power control device A controls a throttle valve 22, not mechanically connected with an accelerator pedal 20, to be opened and closed in accordance with a control of the accelerator pedal 20. In a throttle valve control circuit 34, if a slip rate between a tire and a road surface, calculated by a wheel speed obtained from a rear wheel speed sensor 30 and a car body speed obtained from front wheel speed sensors 31, 32, increases to a preset value or more, the throttle valve 22 is controlled to its fully closed direction. Further the throttle valve 22, when it is fully closed, is released from the full closing in a region where rear wheels 16, 17 are placed in a deceleration condition further with the slip rate exceeding the preset value. Accordingly, the control device A earlier starts a control of full closing, if a driving wheel slip begins to high increase, while earlier performs the release of the full closing if the slip begins to focus.

Title: Four-wheel drive vehicle
Inventor: HARA TOMOYUKI
IPC: B60K17/348
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To provide a four-wheel drive vehicle prevented from the generation of a gear squeal or the like even at the time of mutual connecting action between the dog teeth of wheel clutch mechanism in order to put a vehicle in a four-wheel drive state during the travel of the vehicle. SOLUTION: When the supply of operating quantity (operating air) from a wheel clutch control means is stopped due to some cause during the travel of a vehicle selecting a two-wheel drive state, wheel clutch mechanism 18a, 18b are put in action to connect an auxiliary propeller shaft 26 to auxiliary driving wheels 12FL, 12FR. At this time, rotating speed difference is generated between a drive gear of the wheel clutch mechanism connected to the auxiliary propeller shaft side and a sliding gear connected to the auxiliary driving wheel side, but a distribution ratio changing means changes the driving force distribution ratio of a driving force distribution adjusting means so that a driving force distribution ratio to the auxiliary driving wheel becomes the value exceeding zero, thus nullifying the rotating speed difference between the drive gear and the sliding gear.  A hub squeal and the damage of the gears at the time of connecting action of these gears can thereby be prevented.

Title: Packet collision settling system in local network
Inventor: TAKAGI AKIHIRO
IPC: H04L12/413
Filed: 1981-11-17
Abstract: PURPOSE:To reduce a transmission waiting time, by shifting a transmitting right in order from one end of a collision node to the other end, after a collision has occurred, then settling the collision. CONSTITUTION:A node 3-1 of the left end waits until a transmission line 1 becomes a non-signal state, and after that, sends out a packet in both directions on the transmission line. Nodes 3-2, 3-3 receive it, and after that, send each short reserved signal 8, 9 to the right side only. As soon as the signal 8 is received, the node 3-3 stops sending out the signal 9, and waits for the end of packet transmission of a collision node. The node 3-1 sends a packet 10 in both directions after sending the signal 8, since no reserved signal enters from the left.  The node 3-3 sends out a reserved signal 11 to the right side after receiving the packet 10. Subsequently, since a reserved signal of other node does not enter from the left, a packet 12 is sent in both directions after sending the signal 11. After packet transmission of the node 3-3 has ended, the transmission line 1 has no signal. All the nodes are returned to concurrence phase when a non-signal period is detected for a sufficient long time.

Title: Eddy current inspecting device
Inventor: ANDO SEIGO
IPC: G01N27/90
Filed: 1986-08-07
Abstract: PURPOSE:To achieve a higher inspecting accuracy, by making an AC magnetic field cross the inner surface of a steel pipe to detect pitting from changes in the magnetic field while erroneous detection of an output voltage is prevented with a signal processing circuit as caused by changes in the relative distance between a magnetic sensor and the inner wall of the pipe. CONSTITUTION:As a detection head having a plurality of secondary coils 3a-3n outside a primary coil 2 is moved in a steel pipe, an induced voltage of the coil 3a approaching pitting changes and is outputted from a synchronous detector 10. The output voltage is averaged with a movement averaging circuit 13 and fed to a differential amplifier 14 cleared of a pitting signal. The amplifier 14 determines a difference between an output of the detector 10 and an output of the circuit 13 and only the pitting signal is outputted with a higher S/N ratio. This can prevent erroneous detection of an output voltage due to changes in the relative distance between the secondary coil and the inner wall of the pipe as caused by the flatting of the steel pipe and variations in the diameter thereof thereby achieving a higher inspecting accuracy of pitting.
