Inventor: SASAKI KAZUO
IPC: E04H12/28
Filed: 1987-07-07
Abstract: PURPOSE: To enable disassembly work to be implemented safely and economically by making a plumb bob pendent from a rod loosely drop on the central axis of a funnel-shaped cutting edge body put on an opening of a cylindrical concrete structure opened by its upper end. CONSTITUTION: A funnel-shaped cutting edge body 12 having a larger outer diameter than the maximum diameter of a structure 10 is placed on an opening end of the hollow cylindrical concrete structure 10. Next, a plumb bob being fitted loosely in a rod 18 is pendent from a central axis of the cutting edge body 12 by being wound up by a winch 28 via sheaves 24, 26. In addition, by the use of a diameter expanding jack 16, the cutting edge body 12 is opened in diameter, an then the winch 28 is released in order to permit the plumb bob 22 to fall down and thereby the structure 10 is broken at once.

IPC: B01J38/12
Filed: 1981-10-21
Abstract: PURPOSE:To regenerate the activity of a deactivated Co-Mo catalyst well and to prevent the clogging of a catalyst bed, by a method wherein combustible substances deposited on said deactivated catalyst are removed by burning and the resulting treated catalyst is slurried in water to be washed. CONSTITUTION:In regenetating a Co-Mo catalyst used in hydrodesulfurization reaction, at first, oxygen and steam are blown into a reactor accommodating said catalyst to perfectly burn off combustible substances deposited thereon at 350-500 deg.C. After cooling, accumulated substances in the upper part of a catalyst layer is removed and the treated catalyst is slurried in water, fluidized therein to be washed and finally dried to be screened. When the regeneration is carried out as described above, the activity of the catalyst is made well and the clogging of a catalyst bed is hardly generated.

Title: Controller for vehicle's electromagnetic clutch
Inventor: SAKAKIYAMA RIYUUZOU
IPC: B60W10/04
Filed: 1980-11-28
Abstract: PURPOSE:To prevent an engine brake from no working in such a way that when a vehicle speed detecting means is in trouble, it is coupled to a clutch except when it is involved in speed change operation. CONSTITUTION:Signals from an accelerator switch 41, a top gear switch 42, an engine revolution switch 43 are given as input to a trouble detecting circuit 51. Vehicle speed signals are given as input from a vehicle speed switch 44 to a trouble detecting circuit 51 and an NAND gate 64, and when the vehicle speed switch is in trouble, an NAND gate 57 in the trouble detecting circuit gives low level as output. In consequence, an NAND gate 61 is involved in high level, and when a speed change switch 45 is turned OFF, a clutch is coupled by means of turning ON a transistor 67 through NAND gates 62, 64. Since the clutch is coupled when the vehicle speed switch is in trouble, an engine brake can be available informing the driver of the trouble.

Title: Picking device
Inventor: HIRANO YUKIO
IPC: B65H3/08
Filed: 1990-06-26
Abstract: PURPOSE:To reliably separate sheetform soft works one by one to lift it up by raising a suction pad, adsorbing a work, in order, from the one of side to the other side at intervals of a given time by means of an elevating drive device. CONSTITUTION:When a topmost work 1 is lifted, in order, from the front end part, during the starting of the rise of a suction pad 2, only the front end part of the topmost work 1 is lifted by means of a suction pad next to a frontmost suction pad. Thus, since the area of the lifted topmost work 1 is small, a vacuum state between the topmost work 1 and an underlaying work 1 is instantaneously rendered non-vacuum through inflow of slight air to a gap between the lifted topmost work 1 and an underlaying work 1 positioned next to the topmost work. As a result, a vacuum state is hardly generated between the front end part of the topmost work 1 and the front end part of the underlaying work 1, and the underlaying work 1 is prevented from rise in a state that it is sucked to the topmost work 1.
