Title: Transfer system for control information of remote station
Inventor: ASAI TOSHIO
IPC: H04M11/00
Filed: 1981-04-16
Abstract: PURPOSE:To make a private data transfer line unnecessary and to economize the control of a remote station, by transmitting control information from the remote station through a subscriber's line. CONSTITUTION:Control information such as the temperature related to the house or the like of a remote station (unattended) are gathered by sensors 23-26 and are connected to an unused subscriber's line 26 through a transfer device 6. When control information are inputted to accepting parts 61-63, a special number generating part 64 is started to set the cell state to the subscriber's line 26. In this case, a subscriber to which contorl information should be transmitted is called, and the connection between subscribers, as it were, is performed. Further, the line is occupied only in a time required for transmission of information to transmit control information.

Title: Monopulse antenna device
Inventor: INOUE MASATO
IPC: H01Q21/20
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To evade such case where the radar cross section of an antenna measured at the target side is maximized even in a target tracking state by placing four radial waveguide feeding probes in a point symmetrical form to a point that is offset from the center point of a radial waveguide by a prescribed extent. SOLUTION: This monopulse antenna device includes four feeding probes 9 which are placed in a point symmetrical form to a virtual center point 18 that is offset from the center of a radial waveguide by a prescribed extent. In such a constitution, the relative positions vary between the proves 9 and an exciting probe 6 respectively and accordingly the exciting phase set against an element antenna has a deviation compared with a no-offset state. The both sum and difference patterns have the similar deviations in the beam direction in proportion to the offset value S. Thus, it's possible to properly reduce the radar cross section from its maximum value in the beam direction by selecting the proper offset value S.

Title: Hydraulic driving device for construction equipment for civil engineering
Inventor: HIRATA TOICHI
IPC: F15B11/00
Filed: 1989-03-13
Abstract: PURPOSE:To eliminate fluctuation in a speed change caused by temperatures of actuating oil by varying a pilot pressure which serves to open branch flow compensation valves controlling differencial pressures in front and behind of flow rte control valves, according to the discharge flow rate of a main pump. CONSTITUTION:A pilot pressure is increased by a pilot pressure variable means 61 when a discharge flow rate from a main hydraulic pump 22 is high, while branch flow compensation valves 35 to 40 are so controlled as to be relatively opened, so that pressure oil is rapidly passed through rotary left-run and right- rum motors 23 to 25 and flow rate control valves 29 to 34 which drive a boom, arm, and bucket cylinders 26 to 28. When the discharge flow rate is low, the pilot pressure is decreased so that the pressure oil is slowly passed. In the case that a large rate of flow passes through the main hydraulic pump 22 even at the time of starting under a low temperature, the same rate of oil as this under the normal temperature is supplied to an actuator irrespective of viscosity of actuating oil. In the case that the discharge flow rate is constant, the actuator is driven at a constant speed irrespective of the oil temperature.

Title: Dust removing means for sweeping machine

IPC: A47L9/10
Filed: 1978-05-17
Abstract: PURPOSE: To clean the prefilter surface by adapting a prefilter to be movable in the axial direction and rotatable in association with a dust dropping lever.  
     CONSTITUTION: When a person's hand rotates a dust dropping lever 9, the hand's force is added also in the axial direction. As a result, the dust dropping lever 9 moves toward a main filter 5, so that a dust dropping spring 12 can hit a diaphragm 13 to drop off the fine dust attaching to the main filter 5. On the other hand, with the axial movement of the dust dropping lever 9, a prefilter 4 also moves in the axial direction, whereby the rough dust attaching to the prefilter 4 is more compressed by being pressed against the dust within a dust collecting box 3. Further, the prefilter 4 makes a rotation, which scratches off the rough dust attaching to the mesh 17 for cleaning the prefilter surface.

Abstract: PURPOSE: To effect the control of charging mode of a storage battery with priority to that of its discharging mode depending on the variation in the temperature of the battery and fully charge the battery only when the temperature of the battery is within a prescribed range.  
     CONSTITUTION: When a latching relay 5 is connected to a contact S and the full charging of the battery is being effected and a control signal 101 having been a logic "0" has become a logic "1" at the time to, a signal 103 is produced to shift the latching relay 5 to another contact R to perform trickle-charging. When the voltage of a solar battery falls below a prescribed lower limit at the time t2 in the trickle-charging, a signal 104 becomes a logic "1" but is blocked by a gate 15. Thus, a signal 108 is maintained at a logic "0" and does not connect the latching relay to the contact S. Therefore, the storage battery 4 develops no trouble.
