Title: Ultra-high-molecular weight polyethylene molding and manufacture thereof
Inventor: TAKAHASHI TATSUMI
IPC: B29C45/37
Filed: 1987-07-13
Abstract: PURPOSE:To prevent a skin layer from falling off under loading and to improve surface peeling resistance, by reducing the surface skin layer due to flow orientation. CONSTITUTION:In injection molding or transfer molding, turburent flow is generated on the surface of ultra-high MW polyethylene filled in a cavity by setting projected stripes extended roughly in the perpendicular direction to the flow direction of the resin on the mold surface or by roughening the surface of the mold cavity 3 to reduce the occurrence of a skin layer due to flow orientation. A ultra-high MW polyethylene resin poured in the cavity 3 through a gate 4 flows from the center of the cavity 3 toward to the outer circumference. A plurality of circular grooves corresponding to the projected stripes are formed on a molded item obtained. In this case, to reduce sufficiently the skin layer, the depth (a) of this groove and the thickness (d) of the molded item satisfy a relation represented by a formula: d/1000<=a<=d/10 and the width (b) of the groove and the depth (a) satisfy a relation represented by a formula: a/10<=b<=5a. Moreover, it is preferable that the pitch (p) of the groove and the width (b) satisfy a relation represented by formula: b<p<=100 b.

Title: Electroosmostic dehydrator
Inventor: SHINOHARA TAIZOU
IPC: C02F11/12
Filed: 1983-09-21
Abstract: PURPOSE:To reduce electric power consumption by performing predehydration simultaneously with electroosmotic dehydration by constructing an external cylinder constituted of a front half part with an insulating material and a hind half part with an electroconductive material and arranging conveying screw blades serving also as electrode to the inside of the external cylinder. CONSTITUTION:Sludge 80 is charged from a hopper 15 through an inlet 14 into an external cylinder 10. The sludge 80 moves toward an outlet 16 while being compressed and stirred by the screw blades 30. Since the front half part of the external cylinder 10 is a screen cylinder 11 constituted of an insulating material. The sludge is first dehydrated by the gravity of its own weight. The sludge is further dehydrated by compression by the transporting effect due to the screw blades 30; thus, predehydration is accomplished. The predehydrated sludge is then dehydrated by electroosmosis by being conveyed to the hind half part by the screw blades 30 between a cylinder 12 constituted of a conductive material as an anode and a rotary shaft 20 of the screw blades 30 as a cathode, both serving as counterelectrodes. Contained water is discharged to the outside of the dehydrator through perforated holes 21 on the rotary shaft 20, a conveying passage of filtrate in the shaft, and a water discharge pipe 60.

Title: Sending system for power failure information
Inventor: BEPPU YUICHIRO
IPC: H04B3/46
Filed: 1987-07-15
Abstract: PURPOSE:To recognize a power failure easily by sending a specific power failure signal by the operation of a power failure detection circuit, a specific power failure signal generating circuit and a switching circuit at the time of power failure of a sender side and using a power failure decision circuit at a receiver side to detect the specific power failure signal. CONSTITUTION:If power supplied to a power line 4 of the transmitter 1 is interrupted and a power failure takes place, a power failure detection circuit 6 detects a power failure and sends a power failure detection signal to an auxiliary power supply 7, a specific power failure signal generating circuit 80 and a switching circuit 9. When the power failure detection signal is received respectively, the power supply 7 starts to supply power to the transmitter 1 and the specific signal generating circuit 8 generates a specific signal not relating to the signal to be sent substantially and the switching circuit 9 switches the connection of the line 3 to the circuit 8. Thus, after the power failure in the transmitter 1, the specific power failure signal is given to the receiver 2 through the line 3. Then in the receiver 2, when the specific power failure signal is received, the circuit 10 detects the specific signal from the sender to decide that the transmission section has a power failure.

At this time, the film thickness t1 near the end part in the width direction has a height in the position of 5% of the width W from the end part in the width direction, i.e., in the position of 0.05 W from the end part in the width direction.  In addition, the film thickness t2 has a film thickness and a maximum film thickness near the central part of the width W.

Title: Large floating body structure
Inventor: OKADA SHINZO
IPC: E02B3/14
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To reduce oscillation caused by waves and to reduce construction cost by forming uneven shape horizontally at the peripheral edge of a floating body floating on the sea. SOLUTION: A large floating body structure is provided with a large rectangular floating body 21, and four sides of this floating body 21 is formed in rectangular corrugated shape. Rectangular parts 22 of this rectangular corrugation are equal in height and width and set into L-shape. With uneven shape thus formed at the edge of the floating body, when a wave of certain wavelength reaches the large floating body structure, phase difference of wave power is generated. As a result, wave power offsets each other to suppress the oscillation of the floating body 21 caused by the waves. The oscillation of the floating body 21 caused by the waves can therefore be reduced, and cost can be reduced.
