Title: Frequency converting circuit
Inventor: HARA KOICHI
IPC: H04N9/83
Filed: 1993-08-27
Abstract: PURPOSE:To provide a stable high frequency converted carrier chrominance signal just from the end of reproduction by forcedly locking the carrier frequency of the high frequency converted carrier chrominance signal to any specified frequency during a prescribed period just after the reproduction to improve rising performance at the time of reproduction. CONSTITUTION:The configuration of a control means 49, namely, the configuration of an output side band pass filter(BPF) 37', automatic chroma control(ACC) loop filter 42' and automatic phase control(APC) loop filter 44' is changed. Then, a control signal SCNT from an AFC detection circuit 45 is inputted to each hatching block A. The control signal SCNT is a signal to be made active only for prescribed time after the detection time point of a horizontal synchronizing signal and only during this term, the operating state of the output side BPF 37', ACC loop filter 42' and APC loop filter 44' is locked. Since the carrier frequency is locked to about 3.58MHz corresponding to the frequency of a burst signal during this lock period, even while the output of a frequency converter 34 or a multiplier 35 is not fixed like just after reproduction, a picture is not distorted and rising performance at the time of reproduction can be improved.

Title: Multiblade fan
Inventor: SUZUKI KENJI
IPC: F04D17/04
Filed: 1988-08-29
Abstract: PURPOSE:To install a shaft onto a shaft fixing plate with high precision and high strength by directly caulking the shaft having a V-shaped groove onto the shaft fixing plate manufactured from a metal plate. CONSTITUTION:The part of a shaft 7 which is inserted into a shaft fixing plate 8 is worked thinner to form a thin diameter part 7a, and two V-shaped grooves 11 are worked. After the thin diameter part 7a of the shaft 7 is inserted into the shaft fixing plate 8, an upper mold 16 having a ring-shaped projection 18 is lowered, and a groove 13 is formed, and the periphery of the groove 13 is working-hardened. Then, a groove 12 is formed by an upper mold 20 having a projection 22 having the diameter less than that of the projection 18. Therefore, a metal material which is elastically deformed flows into the V-shaped groove 11 of the shaft 7, and fixed with a high strength. Further, the flow of the metal due to the working of the groove 12 is much on the inside in comparison with the outside, and working can be carried out with the less force, in comparison with the case when the groove 13 is not shaped, and the precision of the right angle between the shaft 7 and the shaft fixing plate 8 can be improved.

Title: Ink-jet recording apparatus
Inventor: MATSUMURA HIDEAKI
IPC: B41J2/175
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To stably drive an apparatus even when a difference of a recording head and an ink head of an ink tank changes by setting an oscillation diaphragm to a face perpendicular to a dead weight direction of the ink. SOLUTION: An ink tank 1 and an ink part in a sub tank 9 are connected by an ink tube 3. An atmosphere communication hole 13 is formed in the ink tank 1. An oscillation diaphragm 12 is set perpendicularly to the dead weight direction to a lower part of the sub tank 9. A negative pressure by a head difference of the ink in the ink tank 1 and the ink in a recording head 2 balances with a force sucking the diaphragm 12 upward, thereby enhancing a pressure change absorption effect. The ink in an ink storage part 10 of the sub tank 9 is always kept in contact with the diaphragm 12, enhancing the effect for absorbing the pressure change in the sub tank 9. A pressure absorption part which stably drives even when the head difference of the ink tank 1 and ink in the recording head 2 changes is obtained by the sub tank 9, etc.

Title: Kerosine burning appliance
Inventor: NAKATANI KAZUTO
IPC: F24C5/04
Filed: 1983-11-11
Abstract: PURPOSE:To provide the titled appliance of exceedingly high safety and usability by providing a valve opening and closing in linkage with the up and down motion of a wick in the fire-extinguishing hole of a fire-extinguishing chamber, taper-fitting the valve to the fire-extinguishing hole and blocking the fire- extinguishing hole by means of the valve when the wick descends. CONSTITUTION:When a normal fire-extinguishing operation is carried out, the wick 4 stops at a position higher than that of a fire-extinguishing slit 10, and a fire-extinguishing hole 11 is blocked by the valve portion 13 of a fire-extinguishing valve 12. Since the tapered portion of the valve portion 13 is made equal to the tapered portion 11a of the fire-extinguishing hole 11, the tight adhesion of both portions is exceedingly high. Therefore, it is possible to stably fire-extinguish in 2-3min by causing the wick 4 to sink up to the upper position of the fire-extinguishing slit 10, and at the same time, generation of unburnt gas which is a source of odor generated at the time of fire-extinguishing, can be prevented, thus reducing odor generated at the time of fire-extinguishing. As a result, fire- extinguishment can be positively carried out within a short period of time, and at the same time, any danger produced on the basis of the leakage of raw gas and generation of odor can be prevented.

Title: Extracting method for seal plug and tube
Inventor: SAWADA TAKASHI
IPC: F16L1/024
Filed: 1993-08-27
Abstract: PURPOSE:To insert/extract/fix a plug member in a tube member according to a state of usage by inserting a presser shaft inside a seal packing having up and down two chambers and making a moving position adjustable. CONSTITUTION:In order to seal a tip of a tube by a seal plug the seal plug is easily inserted to a holding part 22 if a cylinder part 21 of the seal plug is inserted in the tube. A mass part, mounted on a tip of a shaft is moved to a lower chamber 26 from an upper chamber 25 by pushing a shaft part 31 of a presser shaft 3. As a sum of a vertical width of the mass part 32 and a depth of both sides wall of the cylinder part of the lower chamber 26 is larger than an inside diameter of the tube, the cylindrical part 21 is pressed to an inner surface of the tube 4 by the mass part 32 when the mass part 32 moves to the lower chamber 26 and a part between the cylindrical part and the inner surface of the tube 4 becomes water tight. To extract the seal plug the mass part 32 moves to the upper chamber by holding a cord 39 and pulling the shaft part 31. Then the cylindrical part 21 can be extracted from the tube easily because there is no mass part 32 pushed the cylindrical part 21 of the lower chamber 26 from inside there.

Title: Resin-coated flexible pipe
Inventor: HIGUCHI HIROSHI
IPC: F16L11/11
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To easily inspect the presence or absence of a hole bored by a driven nail without impairing flexibility and durability and to prevent the generation of noxious gas at the time of burning by forming a resin layer covering a metallic flexible pipe with a specific polyolefin resin. SOLUTION: A metallic flexible pipe, e.g. a thin stainless steel corrugated pipe 1, is covered with a resin layer 2 to form this resin-coated flexible pipe 3. The resin layer 2 is formed with a polyolefin resin having a material copolymerized with ethylene at the composition ratio of 3-5 mol%. The polyolefin resin has little possibility of generating corrosive gas such s hydrogen chloride or generating noxious gas containing dioxin when burned. If the material copolymerized with ethylene has the composition ratio of 3-5 mol%, the end section of a broken resin layer 2 hardly blocks the gas with a nail when the nail is driven to bore a hole on the metallic flexible pipe 1 as a result, and the presence or absence of the hole can be easily inspected.
