Filed: 1994-03-11
Abstract: PURPOSE:To eliminate a need of an auxiliary battery by bringing both power source packs into contact with power input terminals to slide them at the time of attaching and detaching the power source packs and preventing the stop of power supply in the middle of replacing one power source pack with the other. CONSTITUTION:A power source unit 3 is provided with rails 3a and 3b, and they are fitted to grooves 2a and 2b of a power source pack storing mechanism 2, and the power source pack 2 is stored while being slided.

Abstract: PURPOSE:To eliminate the need for an exclusive use of control information line between a time-division switch control part and the unit of a time-division switch to be monitored, by using a time-division multiplex link for call signals for the transfer of control information and return information between the control part and the unit to be controlled. CONSTITUTION:Since control information consists of (n1+1)X8 bits, one piece of control information is multiplexed by control information multiplexing circuit 2 over control information channel (a) of n1+1 continuous frames of time-division mutliplex link 41 and sent to each highway. On the other hand, control information  reading circuits 21-2m of respective highways monitor channel (a) at any time to  read as control information the information of channel (a) for (n) frames after a  start flag is detected, and then transfer it to highway control circuits 11-1m of  respective highways. Return information multiplexing circuit 3i of highway (i)  (i=1, 2...m) multiplexes the return information from control circuit li to time- division switch 1 over return information channel (b) of time-division multiplex  link 4i.

Abstract: PURPOSE: To simplify a construction procedure at a field by making it easier to avoid an interference of a stop bolt for a supporting fixture, in a column while keeping a mounting strength. CONSTITUTION: A supporting fixture 12 is bent in such a manner that insertion surface portions 2 are normal to a pair of vertical sides of a mounting surface 1 for a column 5 so that the fixture 12 has an approximately U-shaped transverse cross section, and a bottom plate 13 is formed at the lower sides of the portions 2 to support the underside of an end of a beam. A groove 15 having a size corresponding to the size of the surface 1 is provided beforehand in a side surface of the column 5 so that the depth of the groove is slightly larger than the thickness of a head of each stop bolt 4 for fixing the fixture 12.  After the fixture 12 is put into the groove 15 and fixed by means of the bolts 4, if slit grooves 7 are fitted onto the fixture 12 from above, the plate 13 supports the underside of an end of the beam 6, in a temporarily fixing state, and thereafter through pins 16 are inserted into through holes 8, 14 to join the column and the beam.

Title: Blower with air velocity controller
Inventor: KINOSHITA HIROSHI
IPC: F04D25/10
Filed: 1979-04-06
Abstract: PURPOSE: To insure the generation of the wind whose velocity can be automatically reduced through the automatic handling of the wind-velocity control member of a wind velocity controller or its manual handling regardless of the revolutions of a vane when a time has elapsed.  
     CONSTITUTION: When a check valve 21-1 is rotated through the automatic or manual handling of a knob 18 until the knob 18 contacts with a stopper 13-2, a wind-velocity control member 33 becomes parallel to the wind current generated by a vane 4. At this time, the member 33 works to rectify and increase in velocity the eddy current air generated by the vane 4 so that more powerful wind than that generated by the vane 4 becomes fed to a narrow range. Next, when the knob 18 is released, a spring 28 is reset. Then, a bevel gear 31 rotates while reduced in speed by a reducing gear group, and the member 33 becomes orthogonal with the wind generated by the vane 4 so that very weak wind can be fed to a wide range.

IPC: G05B19/02
Filed: 1987-02-26
Abstract: PURPOSE:To ensure a simple and quick reoperation by providing a self-holding circuit, etc., to all commands preceding the final command so that a command which is through before interruption of the control is not carried out when the control is restarted. CONSTITUTION:For a sequence controller which controls sequentially four valves, an under-progress signal 4 and an A-valve full open signal 13 are supplied to an AND 30. A self-holding signal (a) of the output of the AND 30 is supplied to the other input terminal of an OR 29 and then to a wipe-out circuit 31 which is turned off when an AND 14 and the signal (a) are turned on and turned on when the signal (a) is turned off to output the signal 4 as an A-valve open command 12. The output of an on-delay timer 33 which works by an exceptional PB 32 is supplied to the AND 30 together with input of an end signal 6. Thus the control can be restarted at its interrupted time point owing to a self-holding state even in case a D-valve which is controlled after a timer circuit has a trouble.

Title: Abnormality detection system for gas insulated switchgear
Inventor: SAKAKIBARA TAKAAKI
IPC: G01R31/00
Filed: 1989-02-23
Abstract: PURPOSE:To enable removal of effect of an excessive voltage caused with an operation of a switch gear by controlling an operation of a partial discharge detecting section by an input signal into a time measuring section for monitoring an opening/closing operation of the switch gear. CONSTITUTION:Switch 28 is always ON and ready for monitoring the presence of a partial discharge. When an opening/closing operation command enters a switching gear, a pulse corresponding to a rising of a command current waveform is outputted to a time measuring section 24 from a receiver 23. The pulse is branched off to be outputted to the switch 28 connected to a corona sensor 27 to turn OFF the switch. In other words, while a discharge is generated between electrodes of the switch gear, information from the corona sensor 27 fails to be inputted into a corona measuring section 30. In addition, as the switch gear operates normally for several ten ms to several sec, the switch 28 is so arranged as to return to the ON state automatically after time of this much passes. This allows the control of an operation of a partial discharge detecting section by an input signal to the time measuring section of the switch gear, thereby removing adverse effect caused by an opening or closing surge.

Title: Triaxial orthogonal type gas laser device
Inventor: TAKEBE SHIN
IPC: H01S3/097
Filed: 1987-02-25
Abstract: PURPOSE:To symmetrize the sectional shape of laser beams, to simplify structure and to miniaturize a device by mounting a blade member extending over the whole region in the longitudinal direction of a discharge section in said section. CONSTITUTION:A first blade member 25 is elongated extending over the whole region of either longitudinal direction of a pair of electrode holders 23, 24, and second blade members 26, 27 are each protruded also extending over the whole region of the longitudinal direction of both electrode holders 23, 24 at the centers in the cross directions of both electrode holders 23, 24. The first blade member 25 is formed curvedly, and the second blade members 26, 27 are formed to a planar shape. When an assembly A is turned as shown in the arrow of a broken character by a motor, a laser gas is guided to a curved surface in the direction of rotation of the first blade member 25, and flows into a discharge region. Since the discharge region is rotated, using an optical axis as a shaft, the mode pattern of laser beams outputted takes a symmetric shape at that time, thus allowing working with high precision.
