The controller 11 adjusts the input to the heat source device 8 so that the set temperature where the snow melts is reached. Consequently, the wall surface of the reflector which is covered with the snow can be heated uniformly, so the snow can be molten over the entire surface of the reflector and then the reception efficiency of the antenna is increased. Further, the internal wall of the hollow reflector on the side of the antenna device is so constituted that the gas emits its heat and is condensed into liquid, which falls down speedily, thereby utilizing the heating value obtained by the heat source device effectively.

Title: Perpendicular magnetic recording medium
Inventor: YANO AKIRA
IPC: G11B5/66
Filed: 1990-06-20
Abstract: PURPOSE:To improve durability of the medium by forming a Co-partially oxidized film so that the inner tensile stress remaining in the film is a specified value or less and that the ferromagnetic metal grains are needle-like grains having specified short axial length or shorter. CONSTITUTION:The inner tensile stress remaining in the film is specified to <=6.0 X 10<8> dyn/cm<2>, and <=6.0 X 10<8> dyn/cm<2> inner stress can be realized by forming ferromagnetic metal grains needle-like grains having <=10 nm short axial length as the ferromagnetic metal grains. For example, a Co-partially oxidized film is formed as a magnetic film on a polyester terephthalate (PET) substrate 3 by vapor depositing Co with an electron beam heating method 4 in a vacuum vapor deposition device. During this process, oxygen is introduced through a needle valve 2 to perform partial oxidization. Thus, the Co-partially oxidized film is formed to 200 nm film thickness under conditions of 30 deg.C substrate temp. and 0.3 nm/s Co vapor deposition rate. Before the vapor deposition, the partial pressure of oxygen is 6 X 10<-3> Pa. Thereby, the perpendicular magnetic recording medium having excellent sliding resistance can be obtained without providing a protective film.

Title: Diode
Inventor: WAKASA MASAMITSU
IPC: H01L29/861
Filed: 1992-06-19
Abstract: PURPOSE:To provide a diode with stable surge withstand voltage by replacing the P<+> layer of an N<+>-N<->-P<->-P<+> diode by an N<+> region with opposite conductivity type. CONSTITUTION:An impurity out of a surface of an N<-> silicon layer 3 with low impurity density is diffused to form a P<+> layer 4 with low impurity density on an N<+> silicon substrate with high impurity density. Impurity diffusion is carried out through a window part in an SiO2 film 6 to form a circular P<+> region 5 with high impurity density. Impurity diffusion is carried out again at a central part thereof to form a circular N<+> region 8 with high impurity density. When an electrode 7 is positively and an electrode 1 is negatively biased, the electrons injected from the N<+> substrate 2 into a P<-> layer 4 is caused to flow through the N<+> region 8 and reach the electrode 7. Then, when a negative overvoltage is applied to the electrode 7 and a positive voltage to the electrode 1, an avalanche breakdown is caused at a junction between an N<-> layer 3 and the P<+> layer 4, but an NPN structure formed with the N<+> region 8 is put in an on-state. Consequently, an overvoltage is absorbed and the surge withstanding voltage can be improved.
