Patent JP-H04174974-A (JP)
Title: Fuel cell
Inventor: KOTOGAMI YOSHIHIDE
IPC: H01M8/02
Filed: 1990-11-07
Abstract: PURPOSE:To enhance cell characteristics by providing wet seals on both side portions of an electrode each extending along the direction in which gas circulates, and providing in the space between each wet seal and the electrode a gas shielding means for preventing circulation of gas, so as to supply feed gas to the electrode with no loss. CONSTITUTION:Wet seals 12 are formed integrally with a separator plate 3 and provided on both side portions of a fuel gas electrode each extending along the direction in which gas circulates. A tube 17 packed in the space between each seal 12 and the electrode serves as a gas shielding means for preventing the gas from flowing into the space. Even if the volume of the gas is increased at the electrode portion and the resistance of the flow is increased or the resistance of a flow passage is increased by a reforming catalyst or the amount of the gas is increased by a reforming reaction, the seals 12 and the tube 17 prevent the gas from flowing into the space, thereby preventing cell characteristics from being deteriorated.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printer which is capable of printing data with a well-balanced lower margin and is free from the disorder of a printed image caused by the ejection of continuously printed matter. SOLUTION: A paper feed roller takes out recording papers P one by one on a paper feed tray and sends them to the downstream. The recording papers P are sent to a printing part B while being brought into contact under pressure with a platen 17 with a pressing roller 23. A printing head 16 is transferred back and forth in the main scan direction and at the same time, ejects an ink droplet to form (record) an image on the recording papers P. On the other hand, a pair of conveying rollers 15 convey the recording papers P intermittently, synchronized with the shuttle action of the printing head 16. A paper ejecting roller 25a sends the recording papers P downstream through a point contact by a serrated protrusion.  A pair of second conveying rollers 27 are set at a standby position where ink dries and strongly hold the recording papers P which have no fear through drying that an image may be damaged. Further, the paired conveying rollers 27 convey the recording papers P whose rear ends are disengaged with the paired conveying rollers 15, keeping the papers P well poised and the printing heat 16 continues its printing action.

Filed: 1994-12-09
Abstract: PURPOSE: To improve strickleproof of a staple and preventing deformation at driving time by providing a coating layer directly in a surface of the staple, and connecting each staple by a bonding agent, to prevent separation of a coating from the staple. CONSTITUTION: A coating agent of a synthetic rein or cellulose nitrate and the like is applied to a surface of a staple 11, to form a hardening coating layer 12, and the staple 11 is parallelly connected to be bonded by a bonding agent 13, to manufacture a connecting type staple. In the case of driving this staple 11 by a stapler machine, a bonding agent layer 13 of strength lower than the hardening coating layer 12 is broken off, to drive into an object the staple 11 without separating therefrom the hardening coating layer 12. Since each staple 11 is bonded by a bonding agent softer than the hardening coating layer 12, even when applied an impact or bending stress at transport time or the like, the staple is prevented from breaking, and a form as the connecting type staple is maintained, without causing an obstacle in use without also apprehension of decreasing a high product value.
