CONSTITUTION:A material 3 to be vapor-deposited is placed into the crucible A made of C or W, the electron-bombardment hot cathode 5 provided around the crucible A is energized by the power source 6 to emit a thermoelectron which heats the crucible A, hence the material 3 is vaporized, and the vapor of the material 3 is injected from the small hole 1 of the upper lid 2 of the crucible A and deposited on a substrate. In this case, the small hole 1 and upper lid 2 are cooled by the adiabatic expansion due to the injection of the vapor from the small hole of the upper lid 2, the vapor of the material 3 is solidified, and the small hole 1 is clogged. Accordingly, a heating filament 4 is arranged close to the small hole 2, connected to the power source 7 in series with the crucible A and heated, and the upper part of the crucible and the small hole 1 are heated by the heat. As a result, the material is not solidified in the small hole, and the vapor deposition is not stopped.

Title: Transfer type printer
Inventor: SUGIMOTO KAZUAKI
IPC: B41J2/325
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent a smudge even when an inexpensive ribbon without a smudge-protecting layer formed on an ink layer is used, and prevent a platen from being deformed as a result of pressing to a thermal head for a long time in a transfer printer. SOLUTION: When a printing operation is not carried out, a thermal head 1 is raised by a self-retaining type solenoid 19 to a separate position from a platen 8. At the printing time, the raised state is released, so that the thermal head 1 is pressed to the platen 8. When the printing operation is stopped, a pressure of the thermal head 1 does not act to a ribbon and a paper, thereby preventing a smudge. When a transfer printer is transported or stored, etc., since the thermal head 1 is raised to the separate position from the platen 8 by the self-retaining type solenoid 19, the platen 8 is prevented from being deformed at a pressed point which would be caused when the platen 8 is pressed by the thermal head 1 for a long time.

Title: Package
Inventor: NAGAMI SEITARO
IPC: F24H1/00
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To make difficult for a package to fall down and also to pack it compactly by packing an apparatus while being inclined with respect to a posture at the time of normal use to shift the center of gravity of the machine toward a center of a bottom of the package. SOLUTION: An apparatus, a hot water supplying device 1 for example, is packed in a case 2 while it is supported in an inclined state by a bottom pad 3 and a top pad 4 each having a pressure receiving face fitted to a bottom shape and a top shape of the machine. Thus compared with a case where the device 1 is packed in a usually used posture, the center of gravity W is shifted toward the center of a bottom of the package, making the package difficult to fall down. In addition, it is not necessary to increase a size of the case 2 for preventing it from falling down. Since the bottom pad 3 and the top pad 4 also serve as a means for tilting the device 1 and a cushion for protecting the device 1, a material with both shape retention to some degree and cushioning property such as foamed styrene for example may be preferable.

Title: Direct current power cable
Inventor: TERAJIMA KAZUKI
IPC: C08L23/26
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To improve an insulating characteristic while lowering storage of space charge in a solid insulating body due to the applying of direct current high-voltage, and improve a direct current characteristic in comparison with a cross-linked polythylene cable by using a resin composition obtained by graft- polymerizing a maleic anhydride with polyethylene, with which ethylene is polymerized by using the Ziegler-Natta catalyst, as an insulating material. SOLUTION: Density of this polyethylene is desirably set at 0.92 g/cm<3> or more and melting point thereof is 15-degree C more higher than that of a cross- linked polyethylene cable so as to improve the heat resistance. Density is desirably set at 0.935 g/cm<3> or less so as to prevent the deterioration of an extruding characteristic. Maleic anhydride at 0.005-0.05 wt.% preferably is polymerized with a non-polar polyethylene, and a polar carbonyl group is evenly distributed so as to prevent the generation of a local trap of space charge. Since the cross- linking is not performed, influence of a decomposition residue of the organic peroxide to be a cause of storage of space charge is eliminated. Space charge is lowered so as to improve the direct current breaking strength.
