Title: Oil-water separation filter
Inventor: ISHIZAKI ISAO
IPC: B01D17/022
Filed: 1986-03-27
Abstract: PURPOSE:To separate oil efficiently, continuously, and selectively by surrounding the outer surface of a porous duct with an oil proof pressure surrounding body having at least one oil outlet at intervals. CONSTITUTION:The porous duct 2 having 1.0-7.2mum mean pore diameter is pierced through the oil-proof pressure surrounding body 3 provided with the oil outlets 4 and 5 in the axial direction of the body to form a filter 1, and a space 8 is formed between the inner surface of the surrounding body 3 and the outer surface of the duct 2. A fluid mixture inlet pipe 9 and a treated fluid mixture outlet pipe 10 are connected to the respective end parts of the duct 2. A fluid mixture of oil and water is introduced along the inner wall of the duct 2 in the lengthwise direction, for example, in the direction shown by the arrow 7. Only the oil in the fluid mixture introduced under pressure is selectively separated by the porous body, flows out into the space 8 formed with the outer surface of the duct 2 and the inner surface of the surrounding body 3, and then further flows out to the outside of the system from the oil outlet 4. The oil freed of water is obtained in this way.

IPC: H04L7/00
Filed: 1984-04-06
Abstract: PURPOSE:To improve remarkably the reliability of the entire digital device operated by a basic clock and also to reduce the manufacture cost by forming duplicated clock oscillation and allowing the other clock to reset the entire digital device even if one is stopped. CONSTITUTION:When the device is normal, oscillators 3, 4 oscillate clock pulses CLK1, CLK2 of the same period, the input to stop detecting timers 5, 6 is normal and both detected outputs are at an L level. Thus, either of both the clock pulses of the oscillators (e.g., oscillator 3) is outputted to an output terminal 10. If the oscillation of the oscillator 3 stops at a point of time A, the timer 5 detects it and outputs an oscillation stop signal CLK1OUT of H level at a point of time B, a discrimination flip-flop circuit 7 a CLK1ENB of an L level and a CLK2ENB of an H level to tri-state buffer elements 8, 9 at a point of time B and an input CLK2 of the buffer element 9 is outputted to an output terminal 10. Further, the output of the timers 3, 4 outputs a reset pulse via an OR circuit 11 and a monostable multivibrator 12 to apply initial start of the entire device.

CONSTITUTION:A reproducing FM signal which is reproduced from a rotary magnetic disk 1 by a reproducing head 2 is inputted to the one side of the input terminal of a frequency conversion circuit 12 and a signal with a single frequency f0 from a reference signal source 11 is inputted to the other side of the input terminal and from the frequency conversion circuit 12, the reproducing FM signal of the difference frequency of these two signals is outputted. In the period that the picture of the second field is reproduced, the high frequency reproducing signal that is delayed for 0.5 horizontal period at a delay circuit 4 is inputted to a video signal demodulating circuit 6 and by demodulating the signal, a video signal of the second field is obtained. Assuming that the carrier-frequency of the reproducing FM signal that is made to delay at the delay circuit 4 is 14mHz, the passband of the delay circuit 4 is enough to be 14+ or -4mHz.

Abstract: PURPOSE: To form a sharp rugged pattern on a substrate surface without causing any damage to the substrate by a method wherein an ultraviolet (electron beam)- curing type coating material applied on the substrate surface is pressed by a relief printing roll and then it is cured by irradiating with ultraviolet rays (electron beams).

Then, the substrate coated with the coating material is passed between a feeding means (e.g., a roll) and the relief printing roll provided with protuberant parts corresponding to the recessed parts of the desired pattern, thereby imparting the rugged pattern to the uncured coated film. Thereafter, the coated film is cured by irradiation with ultraviolet rays (electron beams).

Abstract: PURPOSE:To prevent boots from being cracked, by eliminating the generation of a small curvature part and a clearance in the vicinity of the peripheral end part of a spiral cir-clip when it is mounted. CONSTITUTION:A spiral cir-clip 10 is designed so that a number of turns of the winding, when the cir-clip is mounted, previously obtains almost 7/4 turns. The spiral cir-clip 10, spreading its internal diameter in the free condition, is mounted to a boots groove 9. Consequently, the spiral cir-clip 10 comes to tighten a boots large opening edge part 8 to a peripheral groove 15 of a socket 11. While also a part in the vicinity of a peripheral end part 21 of the spiral cir-clip 10 comes to be brought into close contact with the internal peripheral side with no generation of a small curvature radial part. Accordingly, when the spiral cir-clip is mounted, a crack of the boots is eliminated by generating no small curvature part and clearance in the vicinity of the peripheral end.

Title: Thermal switch for high temperature

IPC: H01H37/58
Filed: 1988-03-24
Abstract: PURPOSE:To make opening and closing in high temperature atmosphere sure by arranging such that the material used for an operation plate is released of the magnetic attraction at high temperatures above the Curie point. CONSTITUTION:Under the normal operating condition of a fast reactor, an electromagnet 5 in a thermal switch 10 is in the energized condition, an operation plate 4 is attracted to the underside of the electromagnet 5, and at the same time the upper surface of an opening-closing plate 3 is kept in a condition of contact with the fore-end of an electrode 2. As a result, a current for operating an electromagnet 13 of a driving mechanism 11 is flowing between the electrodes 2, 2 and a control rod 12 is in a retained condition. When the temperature in the reactor rises because of some cause above a certain value which disturbs the operation, the thermal switch 10 becomes off. Namely, because of the physical property of a Curie point material used for the operation plate 4, the magnetic characteristic rapidly decreases, the contact with the electromagnet 5 is released, and the opening-closing plate 3 is simultaneously released from the electrodes 2, 2. This stops the current flowing between the electrodes 2, 2, the magnetic excitement in the electromagnet 13 in the driving mechanism 11 is released, and the control rod is brought to an automatic scram.
