IPC: H04L12/56
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To appropriately cope with the increase of switching desired in the following process by allowing a permanent virtual circuit to transmit a control data packet from a control aggregate to a control processor and controlling the establishment of the virtual connection of a user through a network structure. SOLUTION: A permanent virtual circuit transmits a control data packet from a control aggregate to a control processor, and controls the establishment of the virtual connection of a user through a network structure. For example, a node control aggregate 201 controls the set-up and decomposition of virtual connection by writing data in an entrance structure interface, exit structure interface, and shared memory structure memories. When this node control aggregate 201 desires the establishment of uni-directional virtual connection from a line card 211 to a line card 213 by transmitting a control cell to a permanent virtual connection at first and then transmitting this through the shared memory structure to an exit structure interface 225.

Title: Controlling of generator
Inventor: TAKADA HIDEFUMI
IPC: H02P9/04
Filed: 1989-04-10
Abstract: PURPOSE:To effectively operate a turbo generator and a shaft generator by detecting variation in an input vapor amount by a pressure signal oscillator, comparing the pressure signal with a set pressure to obtain a deviation, automatically altering the set value of a governor in response to the deviation, and subsequently automatically altering the opening of a vapor amount control valve. CONSTITUTION:When an output of a main engine 1 is raised, vapor amount is increased, a pressure detection signal is compared with a set pressure to automatically obtain a deviation signal. This deviation signal automatically raises the set value of a governor 18 to increase the opening of a vapor amount control valve 16, and the output and frequency of a turbo generator 19 are raised as compared with reference values. The frequency is automatically detected to so control it as to reduce the output of a shaft generator 21. Then, the sharing power of the generator 19 is increased, and the sharing power of the generator 21 is decreased. Here, in the case of the deviation in which the vapor pressure is higher than the set pressure, marginal power is supplied to the generator 21 if the generator 19 has room for load.

Filed: 1986-04-18
Abstract: PURPOSE:To miniaturize a housing, by installing an engaging member at the outside of the housing, in case of a steering lock device provided with a double- operation safety mechanism. CONSTITUTION:The engaging member 8 attached to a fulcrum shaft 7a of a housing 7 makes its side face 8b at the central part contact with an outer surface of the housing 7. And, when a key cylinder is put back to a lock position from an on-position and rotated, an engaging surface 4c of a cam member 4 comes into contact with a projecting part 8d of the engaging member, checking its return rotation. Here, if an operating lever 10 is pulled downward, the engaging member 8 is rotated counterclockwise, whereby the engagement between the projecting part 8d of the engaging member 8 and the engaging surface 4c of the cam member 4 comes off, thus return rotation to the lock position is made performable.

Abstract: PURPOSE:To detect the position of an object to be detected with an excellent precision even on a specific condition by arranging two photoelectric transducers at an interval one-dimensionally to detect the position with a slight change of the detection precision even if the size of the object to be detected is changed. CONSTITUTION:The image of an object 15 to be detected which is illuminated with an illuminating device 14 is formed onto two photoelectric transducers 19a and 19b, which are arranged at an interval one-dimensionally, by an image forming lens 16. The detection signal of brightness of the image is inputted to a controller 17, and the image is moved in the arrangement direction of photoelectric transducers 19a and 19b by a scanning signal from the output of the controller 17. On condition that an interval (a) satisfies a<2d and a/2+d<D< a+2d, the position derection precision is improved. Since two photoelectric transducers are arranged at an interval one-dimensionally, the position of the object to be detected is detected with a slight change of detection precision even if the size of the object is changed. On a specific condition, the position of the object to be detected is detected with an excellent detection precision.

Title: Cylinder group discrimination device of internal combustion engine
Inventor: KATO TATSUNORI
IPC: F02D45/00
Filed: 1995-04-14
Abstract: PURPOSE: To discriminate a cylinder group and detect a crank angle stably based on a few memory data when a rotation change is big like the start time of an internal combustion engine. CONSTITUTION: In the rotary body 1 installed on the crank shaft 6 of an internal combustion engine, projections 2, 3, 4, 2', 3', 4' at a prescribed angle position as for a crank angle discrimination and projections 5, 5' at a prescribed angle position as for a cylinder group discrimination are formed respectively on its outer periphery. It is discriminated whether or not a discrimination function T1<2> -K(T0×T2) is more than 0 by using continuous three signal intervals T2, T1, T0 and a prescribed value K of an angle signal outputted from an electro- magnetic pick up sensor 10 based on the rotation of the rotary body 1.  In this case, a cylinder group can be discriminated and a crank angle can be detected stably even when the rotation change is big, as the discrimination function is more than 0 at only the point of an angle signal detection time at the projection 5 due to that the signal interval between the projection 2' and the projection 4 is long.

IPC: H03H9/72
Filed: 1991-03-29
Abstract: PURPOSE:To reduce electrode finger resistance and to improve efficiency for convolution by providing a piezoelectric thin film having acoustic velocity higher than that of a piezoelectric substrate at an interdigital electrode for output on the piezoelectric substrate at least. CONSTITUTION:A piezoelectric thin film 7 having the acoustic velocity of Y- direction surface acoustic waves higher than that of a substrate 1 at least is provided under an interdigital electrode 5 for output on the surface of the substrate 1 at least. The film thickness of the thin film 7 is gradually made thick from the side of a waveguide 4-n in a tapered shape. When an electric signal is inputted to an interdigital electrode 2 for excitation, the surface acoustic waves are excited, and when an electric signal is inputted to an interdigital electrode 3 for excitation, the surface acoustic waves are excited, and the surface acoustic waves are respectively made incident to waveguides 4-1-4-n. For the surface acoustic waves mutually reversely propagated from the both ends of the waveguides 4-1-4-n, the surface acoustic waves propagated in + or -y axis directions are generated to the both sides by a parametric mixing phenomenon. These surface acoustic waves arrive at the interdigital electrode 5 for output, and the convolution signal of two input signals is obtained.

Filed: 1987-04-10
Abstract: PURPOSE:To contrive suppressing noise and vibration and speeding up the revolution of the spindles of a turret drilling machine by providing such an arrangement that a drive friction disc adapted to be made into press-contact with friction rollers coupled to spindles so as to transmit the rotation of a motor thereto, is brought into press- contact with only the friction roller of a spindle located at a specific position. CONSTITUTION:A friction roller 4 coupled to a spindle 3 located at a specific position, is made into press-contact with a drive friction disc 6 so that the rotating direction of a spindle drive motor 5 is changed by about 90 deg., and then the rotation of the drive motor 5 is transmitted to the spindle 3. Since the center axis of the drive friction disc 6 is not coincident with the rotary center axis 22 of a turret head 1, and is inclined, when the friction roller 4 of the specific spindle 3 comes into press-contact with the drive friction disc 6, friction rollers 4 of the other spindles 3 are separated from the friction disc 6 so that the rotation of the drive motor 5 is transmitted to only the spindle 3 located at the specific position. Thus, in the rotary transmitting mechanism, the friction rollers 4 of the spindles 3 are brought into press-contact with the drive friction disc 6 for transmitting the rotation of the motor 5 so that the rotation is frictionally transmitted, thereby it is possible to speed up the rotation of the spindles 3.
