Title: Load decentralizing system for packet exchange
Inventor: HIWATARI YOSHIMI
Filed: 1986-02-24
Abstract: PURPOSE:To improve the processing efficiency of the entire exchange by assigning a packet processing unit at every logic channel on a packet multiplex communication line so as to decentralize a load finely. CONSTITUTION:When a connection request between the logic channel line #11 of a packet multiplex communication line 2a and the logic channel line #21 of a packet multiplex communication line 2b exists, a connection controller 5 selects a packet processing unit 3a having the least load at this point of time. Then a command is given to a line exchange switch 1 so as to connect the logic channel lines #11, #21, accommodated in the packet processing unit 3a and lines #a2, #a3 in the logic channel unit. Thus, an optional packet multi plex communication line is connected finely in details.

Title: End structure of optical fiber
Inventor: KASHIWAZAKI AKIRA
IPC: G02B6/02
Filed: 1995-02-24
Abstract: PURPOSE: To make it possible to obtain high-efficiency optical coupling without requiring a high-accuracy fixing operation in the case an optical fiber is packaged and fixed to a laser beam source by expanding the core diameter at the front end of the optical fiber having a conical shape at its end. CONSTITUTION: The shape at the front end 4 of the optical fiber 2 is worked to the conical shape having the center at the end face of the core 3 as its vertex. The light emitted from the front end 4 of the optical fiber 2 formed with a taper angle θ is refracted by the end face and is condensed to the inner side and, therefore, the spot diameter of the exit beam is reduced. The shape of the core 3 of the optical fiber 2 is formed large in the core diameter at the front end 4 of the optical fiber 2. Then, even if the light emitted from a laser diode deviates from the center of the optical fiber, the core diameter is expanded and, therefore, the exit light can propagate successively in the optical fiber 2.  As a result, the drastic deterioration in coupling efficiency does not arise even if the central (vertex of the cone) position of the core end face deviates slightly from the center of a beam waist at the time of packaging and fixing.

Filed: 1985-02-26
Abstract: PURPOSE:To provide a room heating which does not occupy the living room space by sealing a heat accumulating material in the inside of walls, floors, pillars or on the ceiling or by installing a panel in which a heat accumulating material is sealed. CONSTITUTION:A heat accumulating material 3 that has the property to be supercooled is sealed in the inside of a building material or a panel. A plate 1 (a material of high heat conductivity such as a metal plate) that is not heat insulating is used as a material for at least the faces of the building material and panel that face the living room space. For the material to accumulate heat a material that has melting point over 50 deg.C in the process of temperature rise and has supercooling property with freezing point below the room temperature in the process of cooling by itself. After this heat accumulating material is heated over its melting point by an electric heater 4, using night electric power, it is left in molten state and left to cool to the room temperature. When room heating is required, the heat accumulating material in molten state is solidified by giving local shearing stresses. This heat accumulating material is preferably sodium acetate tri-hydrate dispersed in xanthen rubber. Discharge of latent heat is started by operating a trigger device 5.

Title: Transfer system for plural incoming calls
Inventor: SAITO YASUKO
IPC: H04M3/54
Filed: 1989-02-16
Abstract: PURPOSE:To transfer a call to a transfer receiving subscriber as long as one of circuits of the transfer receiving subscriber is kept idle by securing such a constitution where a switchboard decides the idle one of plural circuits of the transfer receiving subscriber based on the registered key number and transfers the idle circuit. CONSTITUTION:The telephone numbers of transfer receiving subscribers 7 are registered to a transfer sending switchboard 5 via the calling subscribers 1, 2 and 3 with use of a key number. When the subscribers 7 receive the calls, the switchboard 5 decides based on the registered key number whether either one of those subscriber circuits 7a-7c is idle or not. If so, the incoming call is sent to the subscriber 7. Thus it is possible to transfer plural incoming calls addressed to the same subscriber 7 to the due subscriber 7 as long as the circuits 7a-7c include an idle one.

Title: Acoustic impedance converter
Inventor: HONDA TOSHIHISA
IPC: G10K11/02
Filed: 1992-02-25
Abstract: PURPOSE:To obtain optimum acoustic impedance by adding high molecular resin or carbon to the same material as an ultrasonic oscillation element to form an acoustic impedance converter.

Title: Electrical type meter device
Inventor: HAYASHI NORIO
IPC: G01D11/00
Filed: 1994-02-10
Abstract: PURPOSE:To automatically move a pointer to an initial position by generating a sweep signal for restoring the pointer to an initial position and operating a coil driving means by the signal. CONSTITUTION:A pointer 5 fitted on a rotational axis 3 rotates from the set initial position to direction A by mutual attracting force of a fixed permanent magnet corresponding to a movable permanent magnet 6 and the magnet 6. The initial position is position 0 for the pointer 5. Therefore, even if the magnet 6 rotates max. 180 deg. in the direction A forcibly against the magnetic force of the fixed permanent magnet, the attracting force of both the magnets restores the pointer 5 to the initial position when the power supply is turned off. However, when the magnet 6 rotates 180 deg. or more, the pointer 5 restores in the reverse direction by the attracting force and a stopper 7 blocks its return to normal initial position. In this case, a sweep signal is generated in a sweep signal generating means 13 by turning on the power supply or manual operation so that a coil driving means 12 will drive coils 8 and 9. Then, the rotational axis 3 rotates in a synthesized magnetic-field direction of both the coils, that is, direction B, and returns the pointer 5 to the initial position automatically.

Gain sections 109 and 111 give a gain to the signals 105 and 107, respectively, and add a bias voltage 117 by voltage addition circuits 113 and 115. A feedback signal 119, namely either of the addition signals, is supplied to an addition circuit 125 via a D/A converter 21, and a speed deviation signal 129 that is obtained by adding the signal to a speed command value signal 127 is supplied to a comparator 131.

Title: Seat belt take-up device
Inventor: TAGUCHI MASAHIRO
IPC: B60R22/44
Filed: 1983-03-08
Abstract: PURPOSE:To enable a seat belt to be comfortably attached by bringing a take-up force of the seat belt to zero in attaching the seat belt while taking up the seat belt only when looseness takes place in the seat belt during attaching it. CONSTITUTION:When a seat belt is withdrawn to be worn, a slip joint for guiding the seat belt is swung to open a slack sensor 7 attached to the slip joint. Also, since a buckle sensor 52 is then opened, the outputs of filter circuits 91A, 91B become H, one shorts 92A-92D do not generate the outputs and a motor 2 becomes inoperative. Next, when a tongue plate is combined with a buckle, the buckle sensor 52 is closed and the one shot 92A generates the output pulses for a predetermined time. Thus, current is supplied to the motor 2 through a motor drive circuit 92G and a voltage supply circuit 92H to take up the seat belt.
