Title: Sheet feeding mechanism with back tension device
Inventor: KANEZUKA HIDEO
IPC: G06K13/26
Filed: 1991-04-09
Abstract: PURPOSE:To provide a sheet feeding mechanism which reduces the change of a back tension by increasing the diameter of a rear pulley on the rear side, in a feed direction, of a recording sheet to a value slightly higher than that of a front pulley and intercoupling the two pulleys through a belt. CONSTITUTION:Front and rear pulleys 5 and 6 are coaxially fixed on the respective rotary shaft of a drive drum 1 and a rubber drum 3. Since the diameter of the rear pulley 6 on the rear side, in a feeding direction, of a recording sheet is slightly higher than that of the front pulley 5, the rear pulley 6 is rotated at slightly lower speed. In relation to the drum to which the pulley is coaxially fixed, the rubber drum 3 on the rear side is rotated slightly more slowly, a back tension is produced at a recording sheet 2. Since the recording sheet 2 is pressed against the surface, made of rubber, of the rubber drum 3 by means of a pressure drum 7, the recording sheet 2 does not slip. When, from a point of view of the nature of belt transmission, a load higher to some extent is applied, idling occurs, whereby by properly selecting a belt 4 and the pulleys 5 and 6, a proper back tension is produced at the recording sheet 2.

Title: Adaptive control method and its device
Inventor: KOSAKA MANABU
IPC: G05B13/02
Filed: 1993-04-01
Abstract: PURPOSE:To simplify a pre-processing when a system is made robust by obtaining a dead zone width based on the characteristic of a controlled system and executing an identification rule processing and a control rule processing only when control input is larger than the dead zone width. CONSTITUTION:A dead zone width holding part 7 obtains and holds a dead zone based on the characteristic of the controlled system 2. The parameter of the controlled system 2 is identified by supplying the respective output values of a controller 1 and the controlled system 2 through low pass filters 3 and 4. The output of the identifier 5 is supplied to the controller 1 as gain change indication data through a swtich 6. The output value of the controlled system 2 is fed back to the controller 1. When a control input value is within the range of the dead zone, a size discrimination part 8 discriminates it, controls the switch 6 to an OFF-state and sets it to a state where adaptive control is not executed. Thus, the pre-processing can be simplified, only control input beyond the range of the dead zone is adaptively controlled and the system can be made robust.

Title: Selection of optimum receiving antenna from more than two receiving antennas
Inventor: BUYORUN OROFU PIITAA EKERUNDO
IPC: H04B7/26
Filed: 1991-04-09
Abstract: PURPOSE: To provide a method for selecting an optimum reception antenna from the two or more antennas of a mobile station in time division multiplex radio communication. CONSTITUTION: Signal strengths S1 and S2 received by the two separated antennas fluctuate along with the time. A code T indicates a time slot at the time of transmitting information to a station which is about to select one of the two receiver antennas. The signal strengths S1 and S2 are respectively measured over the appropriate number of times in a measurement period M. The signal strength S2 is provided with an average value higher than the signal strength S1 in the measurement period M, however, since the signal strength S1 is higher than the signal strength S2 over the large part of the time slot T, it is more suitable to select the antenna 1 provided with the signal strength S1 than the antenna 2. The adaptation is judged by calculation depending on both of the signal strength and the time differentiation.

Abstract: PURPOSE:To compact the ground strongly by inflating an airtight tube with a pressurized fluid, expanding a cylindrical textile having irregular diameter through a sheet material, pressing the inside surface of a hole provided in the ground, and squeezing off the water from the surrounding ground. CONSTITUTION:A small hole is bored in the ground from the surface, and a compacting tool 1 is inserted to a certain depth. At this time, an airtight tube 3 is slack, and the major diametric portion of a cylindrical textile 2 having irregular diameter is wrinkled, and it is easy to set into the hole. From a pipe 11, a pressure fluid such as pressurized water or compressed air is fed into the tube 3 so that it is inflated. The tube 3 pushes wide a sheet material 4, which pushes wide the textile 2 so that it expands. This causes its surface to press the inside surface of the hole so that the bole diameter enlarges, and the water is squeezed off from the ground area surrounding the hole, and thus the ground is compacted. Therein the sheet material 4 supports the tube 3 situated inside, so that the tube 3 is prevented from swelling out through the mesh of the textile 2 or rupturing.
