Title: Distribution constant type filter
Inventor: IWATA TAKASHI
IPC: H01P1/205
Filed: 1982-06-24
Abstract: PURPOSE:To reduce the heights of dielectrics and the distance between dielectric stages by obtaining a distribution constant type filter which has conductors of L/2 or L.2/3 height on a conductor surface. CONSTITUTION:External conductors 12 which is L'/2 and L'.2/3 as high as a dielectric 3 having a height of L' are provided outside the dielectric 3. Namely, the conductors 12 are provided outside the dielectric 3 for preventing a decrease in dielectric constant to confine lines of electric force in the dielectric, obtaining the effective dielectric constant. Therefore, such reltions are established as L>L' and d>d' although t=t' where L, (d), and (t) are the height, interstage distance, and interelectrode distance of this filter and L', (d), and (t'), are those of a conventional filter.

Title: Light emitting diode
Inventor: ASHIYURAFU UDEIN
IPC: H01L33/40
Filed: 1992-04-27
Abstract: PURPOSE:To obtain a light emitting diode which can emit a blue light clearly at high efficiency by placing a graded concentration layer, in which carrier concentration varies along the direction of thickness, at a Pn junction interface of light emission diode. CONSTITUTION:Since holes from a P-type 6H:SiC graded concentration layer 3 are accelerated toward a P<+>6H:SiC layer 4 through graded doping, larger number of holes pass over a Pn junction and injected from the P<+>6H:SiC layer 4 to an n-type 6H:SiC layer 5 as compared with a normal 6H:SiCLED. Emission intensity of the SiCLED is controlled by doping density of aluminum acceptor but emission intensity increases in the n-type 6H:SiC layer 5 because of transition from free election to acceptor or from donor to acceptor and production of free exciton. When a graded concentration layer is placed at Pn junction interface of a light emission diode, injection efficiency is enhanced without sacrifice of transmittance resulting in significant enhancement of light emission efficiency.

Title: Method of heat treatment of die cast die having water cooling hole
Inventor: FURUYA TADASHI
IPC: C21D9/00
Filed: 1993-05-10
Abstract: PURPOSE:To improve the heat crack resistance by increasing the hardness of the die-sunk surface of the die casting having the water cooling holes inside the die, and to prevent cracking of the die by reducing the hardness of the whole die including the part of the water cooling holes to improve the toughness. CONSTITUTION:After the whole die is held at the quenching temperature, the die-sunk surface is quenched in the hot bath of 180-400 deg.C, the other part than the die-sunk surface of the die is annealed, and then, the whole die is tempered. Alternatively, after the whole die is held at the quenching temperature, the die-sunk surface side is quenched at the cooling speed larger than that of the cooling in the atmosphere while a part except the die-sunk surface is dipped in the hot bath of the temperature of 700-800 deg.C, and dipped in the hot bath of the temperature of >=700 deg.C to <=800 deg.C and quenched at the cooling speed larger than that of the cooling in the atmosphere. After the whole die is cooled, the whole die is tempered. This constitution suppresses the heat crack of the die-sunk surface of the die, and provides the die casting die to prevent the crack from the water cooling holes.

Title: Fusion welding of synthetic resin sheet and vessel made of synthetic resin sheet
Inventor: MAKITA KATSUNOSUKE
IPC: B29L22/00
Filed: 1987-04-30
Abstract: PURPOSE:To permit a lid to be opened easily by only separating a flange part in such a manner that a hook is released, by a method wherein a hot rod is penetrated through the flange of a vessel to weld the lid. CONSTITUTION:A heated small diametral hot rod 24 is penetrated through a main body flange 12 and a lid flange 16 while reciprocating it. By this operation, the synthetic resin sheets of the lid flange 16 and the main body flange 12 are molten and are welded. Further, the resins at the fused part 28 of the main body flange 12 and the lid flange 16 are connected integrally in the through-hole 26 and hook-like welding effect is performed. When the lid of a vessel, welded in such a manner, is opened, the lid 14 can be opened easily by only holding the flange and separating it from the lid since the lid flange 16 is connected to the main body flange 12 through an annular welded part 28 at the welded part 20. Individual bonding forces in the welded part 20 are not so strong substantially, therefore, the welded part 20 may be separated easily by only applying a weak force upon separating it.

Title: Controlling method for operation of air conditioner
IPC: F25B1/00
Filed: 1992-03-16
Abstract: PURPOSE:To prevent blown-up of warm-up air and to improve arrival of the warm-up air close to one's feet by reducing a frequency of a compressor to lower room heating capacity when a temperature in a room approaches a set temperature at the time of room heating of an air conditioner and simultaneously decreasing diffusing air flow rate to a room. CONSTITUTION:A method for controlling room heating of an air conditioner comprises the steps of (S1) first judging a difference Tn between a temperature in a room and a set temperature, (S3) judging a temperature Tr in a room in the case of 1>Tn>=0.5 ( deg.C), then (S4) operating at a first low air flow rate L at the time of Tr<23 ( deg.C), (S5) at a second low air flow rate 2L (<L) in the case of 23<=Tr<25 ( deg.C) or (S6) at a second low air flow rate 3L (<2L) in the case of Tr>=25 ( deg.C). A frequency of a compressor is reduced each time by a predetermined frequency to lower room heating capacity. Further, at the time of Tn<0.5 ( deg.C), it is lowered to an ultralow temperature 4L(<3L) (S8), and simultaneously the compressor frequency is reduced by an amount corresponding to a diffusing temperature. Thus, drafting feeling is alleviated.
