Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To improve elevating function by pivoting a floor plate on a ledger frame in such a manner as to be opened and closed to form a staircase opening part. SOLUTION: This opening and closing ledger frame 1 is so constructed that a ledger frame body 6 is formed by first frames 2, 3 and second frames 4, 5, the end corner of a floor plate 8 is pivoted on the frames 4, 5 by bolts 28 to open and close the floor 8 in the frame 6, and at the time of closing the floor 8, the floor 8 is engaged with the frames 2, 3. In constructing the frame scaffold, a staircase is stretched between the horizontal muntin of upper and lower vertical frame, and a ledger frame 1 is erected between the horizontal muntin between the vertical frames above the staircase. At the time of going up and down the staircase, grips 34 are grasped to open the floor 8 upward to the side of the frame 6, and the frame 6 is opened.  At this time, the frame 6 is prevented from being fallen down due to the wind or the like by frictional elasticity of an elastic member provided on a pivotal part, and an expand metal 18 is laid on the floor 8, whereby at the time of opening the floor 8, the existence or absence of a worker can be confirmed. Thus, in a narrow frame scaffold, the worker can freely pass through the staircase opening part without vertical frames for a staircase on the outside.

IPC: C22C38/42
Filed: 1994-10-14
Abstract: PURPOSE: To produce a metal mold requiring no application of a lubricating parting agent of a mold releasing metal and capable of perfectly preventing the occurrence of cracking even at the time of operation free from oil application by forming the metal mold by the use of Fe containing specific amounts of Cu, Al, Cr, and rare earth elements and specifying the roughness of a molding surface. CONSTITUTION: This metal mold is the one for glass molding, which has a composition consisting of 10-80% Cu, 4-11% Al, 3-16% Cr, 0.02-2.0% of one or more kinds among rare earth elements, and the balance Fe and containing, if necessary, 10-30% Ni and in which the average roughness Ra of a molded surface is regulated to 0.3-5μm. By using this metal mold, the microscopic contact area between glass and the surface of the metal mold can be reduced and the quantity of heat absorbed from glass can be reduced, and as a result, the glass can be prevented from being cooled rapidly and cracking can be prevented. Although the occurrence of cracks and wrinkles, due to supercooling, can be removed when Ra exceeds 3μm lubricity is deteriorated and wrinkles are formed when it exceeds 5μm.  Moreover, similar effect can be produced if holes of <=0.5μm diameter are formed in the whole molding surface at 30-70% area ratio.

Title: Photosensitive material drum
Inventor: TAKESHIMA AKIYOSHI
IPC: G03G15/00
Filed: 1983-12-27
Abstract: PURPOSE:To prevent effectively the dew condensation of a photosensitive body which is formed by providing a photosensitive layer on a thin base plate by winding the photosensitive body around a drum covered with a heat insulator, and thus constituting a photosensitive material drum. CONSTITUTION:The photosensitive body 2 having the photosensitive layer on the thin base plate is wound around the drum formed by covering the heat insulator around the surface of a cylindrical support member to constitute the photosensitive drum 14. Thus, heat conduction between the photosensitive body 2 and drum is cut off and the temperature of the photosensitive body becomes easy to follow up variation in ambient temperature, thereby reducing the dew condensation of the surface of the photosensitive body 2. Therefore, the unusable time of the copying operation due to dew condensation is shortened and a drying heater is not necessary, so that the power consumption is reduced.

Title: Compound semiconductor thin film
Inventor: MATSUMOTO SHINICHI
IPC: H01S5/00
Filed: 1992-09-21
Abstract: PURPOSE:To prevent resistance of semiinsulating highly resistive semiconductor layer from decreasing due to abnormal diffusion by containing semiinsulating dopant at a concentration higher than that of the semiinsulating highly resistive semiconductor layer and substantially equal to solubility limit concentration. CONSTITUTION:Fe is double doped together with Zn, upto the vicinity of solubility limit, into a p-type InP layer 3 formed on an InP substrate 1. Concentration of Fe in an Fe doped InP layer 5 to be grown on the p-type InP layer 3 is set lower than the concentration of Fe double doped into the p-type InP layer 3. Since Fe in the Fe doped InP layer 5 is not diffused into the p-type InP layer 3, initially doped Fe remains as it is in the Fe doped InP layer 5. This constitution prevents resistance of semiinsulating highly resistive semiconductor layer from lowering due to abnormal diffusion.
