Title: Data transmission control system
Inventor: ABE HITOSHI
IPC: H04L12/70
Filed: 1989-11-29
Abstract: PURPOSE:To reduce the processing burden of firmware by counting up an untransmission management counter by packet reception from a packet line and counting down it by the completion of packet transmission to a LAN transmission line. CONSTITUTION:An untransmission management counter 10j for a corresponding line reception descriptor 6j is counted up by one at each time of registration. A data fundamental unit storage address is registered in an idle data fundamental unit storage address register area, which is determined on the control, in a LAN transmission descriptor 8. When the LAN transmission descriptor 8 completes transmission of a data fundamental unit to a LAN transmission line 4, an untransmission management counter 10k discriminated by the line number of the line number register area corresponding to the transmitted data fundamental unit is counted down by one. Thus, the processing burden of firmware for management is reduced.

Title: Take-up collar for friction winding shaft
Inventor: KIKUTAKE NAOYUKI
IPC: B65H18/04
Filed: 1986-12-24
Abstract: PURPOSE:To perform expansion and contraction of a take-up collar outer diameter by manual operation as well as to prevent fixation failure and separation failure from occurring, by rotating an annular ring in a state of clamping a ring, and constituting a rolling element so as to rolled by dint of frictional force. CONSTITUTION:When a sheet is rolled in a core 9, an annular ring 8 is manually rotated from the top of this core 9 in the state that a ring 3 is clamped, and the core 9 is fixed on an outer circumference of the annular ring 8. At this time, a rolling element 7 is moved, as being rotated, toward a shallow side of a stepped part 4 together with a dowel 6 of a side plate 5 by dint of frictional force, widening the annular ring 8 partially cut, and it rolls the sheet in the core as surely unitized with the core 9. In this case, since this stepped part 4 is formed into more than three steps, even in front and in the rear of the step, there is none of a large variation so that the expansion force will not suddenly be increased, thus sufficient tightening force is produced there even by man power. On the other hand, when the core 9 is removed from the collar after winding the sheet, if it is rotated in the reverse direction to the abovementioned, the rolling element 7 is moved toward a deep side of the stepped part 4, whereby the annular ring 8 is contracted and separated from the core 9.

Abstract: PURPOSE:To obtain high-purity silicic acid in high yield, by melting quartz rock or silica sand fed to a melting furnace under heating and continuously drawing silicic acid in a molten state from the melting furnace while finely vibrating the melting furnace. CONSTITUTION:A melting furnace 1 lined with zirconia brick 3 as lining refractory is charged with quartz rock or silica sand as a raw material. Then the quartz rock or the silica sand is heated by a combustion gas jetted through a hole 5 from a burner 4, melted into molten silicic acid 8 and continuously drawn in a beltlike state through an outlet 6 by a drawing device 7 to give a product silicic acid 8'. During the operation, the furnace 1 is finely vibrated in the horizontal direction by two vibration generating machines 9 attached to outer sides of the furnace 1 at symmetrical positions. By the vibration, small gap is produced between the inner face of the zirconia brick 3 of the lining refractory of the furnace 1 and the molten silicic acid 8 in the furnace 1. Consequently, the brick is rubbed and taken out by the molten silicic acid 8 and the brick can be prevented from attaching itself to the outer peripheral surface of the product 8'.

IPC: C02F1/50
Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To reduce the number of equipment, reduce equipment costs and maintenance costs, and surely clean raw water by simplifying the system by integrating an ozone sterilizer with the casing of a foam separator to remove suspended matter from the raw water in a method for pre-treating for cleaning raw water such as seawater, river water, lake water and the like, and also to decrease machine costs, electric power costs or the like by recycling ozone in waste gas. SOLUTION: Raw water and air containing ozone are introduced to the bottom of the casing 1 of a foam separator, or of a plurality of foam separators. When the raw water flows upward in the casing 1, the fine bubbles of the air containing ozone are brought into direct contact with the raw water. In this parallel flow process, suspended matter in the raw water is stuck on the surface of the fine bubbles, and also the raw water is sterilized by the ozone in the fine bubbles. The suspended matter is separated and removed, and the sterilized raw water is taken out to the outside of the casing 1. When occasion demands, waste gas containing ozone or waste gas having higher zone concentration is again introduced to the bottom of the casing 1.

Title: Apparatus for visual inspection of capsule
Inventor: ENDO KOICHI
IPC: B65B57/10
Filed: 1988-12-09
Abstract: PURPOSE:To improve the packing rate of capsules in a supply drum and further the efficiency of inspection by installing bearing members in the manner partially crossing a path in a hopper and a vibrating member approximately parallel to a tangent to a guide in the vicinity of a lower outlet. CONSTITUTION:Pressure near the lower outlet of a hopper 11 under the own weight of capsules 9 in the hopper 11 is partially shared by a lower bearing plate 5 and intermediate bearing plates 6 and 7. Therefore, pressure to the upper face of a vibration frame 4 is reduced and the transfer force thereof effectively acts to smoothly transfer the capsules to the outer face of a supply drum 13. The principal direction of the transfer force caused by the vibration of the vibration frame 4 is parallel to a tangent to one side of the guide frame 8 or the supply drum 13 at the point of the vibration frame 4 because the shape of the vibration frame 4 is square and chevron-shape and one of the sides thereof is parallel to the tangent to the guide frame 8 or the supply drum 13 at the point of the vibration frame 4. Thereby the capsules 9 are easily fitted to the slits 8a and 8b of the guide frame 8 and contained into the recession 13a of the supply drum 13.
