Abstract: PURPOSE:To eliminate the need of a refractive index matching agent and to improve the attaching detaching operability, and also, to obtain a connection characteristic of a low reflection and a low loss by bringing each optical fiber connecting end face into contact obliquely and directly with each other at the time of connecting each plug. CONSTITUTION:A connecting end face 16 of a plastic formed plug 14 becomes the inclined surface incled at a larger angle  - or +  than a total reflection critical angle of a propagation light in an optical fiber from the face being orthogonal to an axis of the optical fiber 2. The optical fiber 2 is fixed by having a small projection amount DELTAL in parallel to the connecting end face 16 on which its connecting end face is inclined. Connection of the plugs 14 and 14' is connected by inserting a pair of guide pins 6 into a pin insertion hole 15 of one plug 14', inserting the plugs 14, 14' from both sides of a guide sleeve 17 and butting them, fitting in a crank spring 7 and pressurizing it in the axial direction.

Title: Single faced corrugated board manufacturing machine
Inventor: ENDO MASARU
IPC: B31F1/28
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a single faced corrugated board manufacturing machine which can minimize the generation of a press mark by reducing press force by a press roll. SOLUTION: A single faced corrugated board 3 formed by supplying a liner paper sheet 2 to the corrugation tops 1a of a corrugated board 1A in a press part B is moved to a guide roll 29. The roll 29 is located in a place in which the board 3 is pressed to a lower step roll 20. Since residual suction pressure is on the side of the roll 20, the board 3 can be moved by being sucked to the roll 2 side through the board 1A. The sheet 2 can be stuck to the board 1A strongly enough by the accelerated gelatinization of paste liquid 5 by the application of a heating action to the position of the guide roll 29 even when press force by a press roll 28 is weak, so that the generation of a press mark by the press force by the press roll 28 can be minimized.

Filed: 1983-11-14
Abstract: PURPOSE:To make stainless steel usable for a material of a heat transmitting pipe and to prevent the heat transmitting pipe from damage due to thermal fatigue by recirculating water to a degree not generating dry patch and increasing the amt. of water per unit breadth of the inside surface of tue pipe. CONSTITUTION:Water or a kind of liquid consisting essentially of water is allowed to flow down forming a wetted wall on a vertical wall 304 heated by a heating medium 302, and gas 301 flowing in contact with the wall is humidified. In this apparatus, an amt. of water more than the amt. of water to be evaporated liquid at the outlet of the wetted wall is recirculated to a liquid feeding sectuon 305 by a recirculating means 310. The flow rate is regulated to satisfy an inequality: Heat flux q<5.99X10<5>T<2.12> [q is heat flux W/m<2>K (W is watt; K is Kelvin); T is mass flow rate (kg/ms) per unit breadth of the wetted wall]. As the result, there is no fear for causing stress corrosion cracking since no dry patch is generated; thus, stainless steel is usable for the material of a heat transmitting pipe, and damage of the heat transmitting pipe due to thermal fatigue is also prevented.

Filed: 1988-08-27
Abstract: PURPOSE:To prevent counter power flow by connecting a series reactor having reactance being set according to the share of each consumer for the output of a common generator between the common generator and each distribution line for the consumer. CONSTITUTION:When each consumer is consuming power exceeding over its own share, a series reactor 8 having reactance being set according to the share of each consumer 5 distributes the common power corresponding to the share. The power is distributed through a link line 6 and distribution lines 4 to each consumer 5, and commercial power is fed through the distribution line 4 to a consumer who consumes power exceeding over its own share. When power consumption of consumer 5a is lower than its own share, the output of a common generator 7 is regulated to the level which is lower than its own share thus suppressing counter power flow.
