IPC: H04B10/516
Filed: 1995-04-05
Abstract: PURPOSE: To utilize a wavelength area efficiently by multiplexing a transmission wavelength of each station from an end of the wavelength area sequentially on a wavelength axis in the order of transmission start. CONSTITUTION: Two kinds of channels are provided for the communication system. In this case, a channel A has a low transmission speed such as from several tens to 100Mb/s and a channel B has a high transmission speed such as 1Gb/s. In Fig. λan (n=1-7) indicates a wavelength of the channel A and λbn (n=1-3) indicates a wavelength of the channel B (a smaller (n) indicates a faster transmission start time). Furthermore, a Δλa indicates a channel interval required for the transmission of the channel A, and a Δλb indicates a channel interval required for the transmission of the channel B.  Then the channel A is arranged with signals at an interval of the Δλa from a shorter wavelength in the order of faster transmission start time, and the channel B is arranged with signals at an interval of the Δλb from a longer wavelength in the order of faster transmission start time.

Abstract: PURPOSE: To shorten a length of time required for closing the guide vane, by providing a driving mechanism for suppressing an opening operation command from a speed detector during a closing operation of the guide vane and making the closing operation continued of the guide vane.  
     CONSTITUTION: When a load is cut off during a water-wheel generating operation, with a guide vane closing command outputted and the guide vane closing, a rotational speed, lowering below the specified value, causes a speed detector to output an opening command of the guide vane. Therefore, at the same time of the load cut off from the water-wheel, until a position switch 27, for setting near to no- load opening degree, operates, with a load limiting device motor 12 driven to rotate a handle 11 in the closing direction, a valve 15 is lifted upward with a point 0 being the supporting point, to drain a pressurized oil through a tube F with a main valve 13 depressed down, and a piston 26 is shifted to the right side by a pressurized oil from a tube E, to close the guide vane. Accordingly, the guide vane continues a closing operation till a rotation of the motor 12 is stopped.

Filed: 1989-03-31
Abstract: PURPOSE:To miniaturize a device by gradually and stepwise shifting front ends of banknotes to be successively carried at the time of clipping these banknotes by clipping rotary bodies to temporarily hold them. CONSTITUTION:An inserted banknote is carried on a carrying path by a carrying means 4; and when it reaches clipping rotary bodies 20, its front end is clipped between clipping rotating bodies 20, and a second banknote is carried; and when it reaches the front of the bodies 20, at least one clipping rotary body is rotated by a prescribed extent to clip this banknote. The preceding banknote is fed out by a prescribed extent at this time, then, plural banknotes are clipped with front ends shifted stepwise and are temporarily held. At the time of returning these temporarily held banknotes, the bodies 20 are reversed by a prescribed extent to release them one by one, and the released banknote is returned to an insertion hole 3. Thus, the whole of the device is miniaturized, and many banknotes are temporarily held and arbitrarily stored and returned.

Title: Rodless cylinder
Inventor: KUBOTA HIDEYUKI
IPC: H01F7/02
Filed: 1994-03-29
Abstract: PURPOSE:To restrain eccentric force from being produced, and prevent the occurrence of erroneous operations by setting the magnetic flux density of a magnetic pole section at the side of a yoke roughly at a magnetic flux saturated condition. CONSTITUTION:Since the magnetic flux density of the magnetic pole section 9b of a yoke 9 is roughly in a magnetic flux saturated condition in the rodless cylinder, even when a piston 7 is made eccentric by some reason with respect to a cylinder tube 6, and even when a permanent magnet 8 and a magnetic pole member 21 are accordingly made eccentric, in a place where a distance between the magnetic pole member 21 and the magnetic pole section 9b in the direction of eccentricity is made small, the magnetic flux density of the magnetic pole section 9b is hardly increased. Even in the direction opposite by 180 deg., magnetic flux density therein is hardly decreased. Therefore, eccentric force caused by suction or magnetic force can be confined in a very small range, this situation thereby can practically prevent the occurrence of erroneous operations such as sliding abrasion or stick slip and the like.

Abstract: PURPOSE:To obtain the adjusting method and zoom lens barrel to allow an easy zooming adjustment by executing the zooming adjustment of the variable focus zoom lens in which the 2nd group is a focusing lens by the movement of the 1st group lens in the optical axis direction thereof. CONSTITUTION:This zoom lens has the respective lens groups of the 1st group A, the 2nd group B and the 3rd group C successively from a subject side. The zooming is executed by changing the air spacing between the 1st group A and the 2nd group B which executes the focusing. The zoom lens of this type is generally required to be adjusted in a manner as to obviate the generation of a focus movement even if the lens is zoomed at a reference object distance (infinite in general) in the assembling. Such adjustment with this lens is executed by the 1st group A with which the position adjustment in the optical axis direction is easier to be made than the intermediate 2nd group B. Namely, a 1st lens frame 22 is turned relative to a 1st lens moving ring 23 in accordance with an adjusting screw 22a in the infinite state, by which the position in the optical axis direction of the 1st group lens A is adjusted.
