Title: Preventing method for corrosion of heating pipe type heat exchanger
Inventor: OGURI HARUO
IPC: F28G1/12
Filed: 1984-02-10
Abstract: PURPOSE:To make neutralize attached oxides as well as enable to remove with dusts, and contrive to improve the prevention of the corrosion and the heat recovery rate, by a method wherein shot balls which carry alkaline powders are made to collide with heating pipes of a heat exchanger. CONSTITUTION:Shot balls which are attached alkaline powders on the surfaces are thrawn down on the heating pipes 3 from an injection hole 8 through a diffusion plate 10, and separate dusts attached to pipes 3 by colliding with said pipes 3 while descending downwards successively, as well as balls are dispersed to make attach alkaline powders carried by balls to the outside surfaces of pipes 3. Owing to the collision of shot balls 5 to the elements etc. of the heat exchanger 4 including pipes 3 in this manner, alkaline powders are dispersed in the exposed part in the exhaust gas, and oxides which are generated attaching to the surfaces of pipes 3 etc. are neutralized and separated together with dusts as neutral salts, and recovered in a collection room 14 at the under part. Accordingly, the oxidation corrosion of heating pipes are the other elements are prevented and the efficiency can be improved.

Title: Thin film transistor element and manufacture thereof
Inventor: TAKAHASHI HIROSHI
IPC: H01L21/336
Filed: 1993-01-14
Abstract: PURPOSE:To realize improvement of electrical properties and integration of a polycrystalline thin film transistor element by flattening the interface between a channel region and a gate insulating film. CONSTITUTION:A thin film transistor element is composed of a polycrystaline silicon semiconductor layer 1 constituting a channel region ch, a conductive layer 3 forming a gate electrode G, and an insulating film 2 forming a gate insulating film OX between the channel region ch and the gate electrode G. The interface 7 between the channel region ch and the gate insulating film OX is flattened. In the thin film transistor thus formed, charges flowing through the channel region ch can move with low scattering probability. Consequently, a large current can be carried. The surface of a polycrystalline semiconductor with large irregularity can be flattened by abrasion. Also, by forming a cap film on the surface of an amorphous semiconductor with small irregularity and making a polycrystalline semiconductor thin film through recrystallization, generation of irregularity due to recrystallization in the direction of film thickness is prevented so that the flattened surface is maintained.

Title: Air conditioner
Inventor: NAKAI MITSUHISA
IPC: F25B29/00
Filed: 1989-02-01
Abstract: PURPOSE:To prevent dew-condensed water from re-evaporating at the time of stopping operating and to dehumidify while preventing temperature fall in a room by providing a flow rate regulator in which a capillary tube for branching a refrigerant flowing circuit and a two-way valve are connected in parallel on the way of the connecting copper tube of an indoor heat exchanger, and installing the indoor heat exchanger in the same ventilation circuit. CONSTITUTION:Throttles 5, 7 are inserted to the intermediate stage of indoor heat exchanger, the exchanger is split into upper and lower parts 3, 2, refrigerant is fed from the upper part to the lower part to operate the upper part of the exchanger as a condenser and the lower part as an evaporator. The air in the room passed through the exchanger is heated in the upper part and dehumidified in the lower part, mixed in the same ventilation circuit in the indoor machine to be diffused. As a result, since the lower part is used as the evaporator, the dew-condensed water in the evaporator can be drained without heating by the condenser. Further, since the approaching area of the evaporator and the condenser can be much reduced, the re-evaporation of the dew-condensed water can be prevented at the time of stopping operation of an air conditioner.

Filed: 1986-02-05
Abstract: PURPOSE:To prevent the floating of magnetic powder from a toner surface by long-period agitation by forming a toner in such a manner that the magnetic powder is tightly adhered onto the surface of the electrostatically charged toner sticking onto the surface of a photosensitive drum. CONSTITUTION:A resin, coloring matter, etc. are measured and mixed. A synthetic resin is melted or softened by a heating kneader, etc., and the coloring matter, etc., are uniformly dispersed into the resin. The kneaded mixture is cooled to permit the easy crushing thereof and the cooled mixture is crushed to 1-3mm size by a hammer mill or cutter mill, etc.; further, the crushed mixture is pulverized to 3-50mum by using a jet mill. The powder of large grain sizes is removed and similarly the powder of very small grain sizes is removed in order to make the powder grain size (toner grain size) uniform. The toner is then put into a softened state by using a heating kneader, etc., and the magnetic powder having the grain size smaller than the toner grain size is added to such toner and is uniformly mixed therewith. The mixed toner is cooled in order to tightly adhere the magnetic powder thereto. The resultant toner has the magnetic powder tightly stuck to the surface.

Title: Data decoder
Inventor: YAMANAKA HISAYUKI
IPC: H03M13/23
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce the arithmetic processing amount of path metric length variable signal generation and to shorten a processing time by deciding the quality of a transmission state in response to the size of a bit error rate and adjusting retroactive length to the past. SOLUTION: A decoding part 51 starts to decode a maximum likelihood path PL at a point of time retroacting to the past, according to a maximum likelihood path PL and path select signal SP which are outputted by a comparator 3. On the other hand, an error-detecting part 61 receives a decoding signal Dn, executes an operation of a bit error rate of every information frame and outputs is as error rate data TE. A transmission-deciding part 53 contrasts the data TE to a corresponding path metric length decision table 54, decides that a transmission path state is satisfactory when the data TE is small, and shortens retroaction to the past in the path PL. When the data TE is large, it decides that the transmission path state is not satisfactory and calculates path metric variable length quantity, so that the retroaction to the past is long.  This drastically reduces an operation amount and a processing time.

CONSTITUTION: In the condition that a piston 2 is moving in the direction of Arrow A, a negative pressure is generated by volume expansion in the first chamber 10 of a cylinder 1, and a suction valve 12V moves in the direction of opening so that the suction port 12 is opened to the external field. A discharge valve 13V moves in the direction of closing, and the discharge port 13 is tightly shut against the external field. A positive pressure is generated by volume expansion in the second chamber 11 in the cylinder 1, and another suction valve 14V moves in the direction of the closing so that the suction port 14 is shut tightly, while another discharge valve 15V moves in the direction of opening so that the discharge port 15 is opened.  This constitution enables execution of the suction and discharge operations of two systems of the first and second chambers 10, 11 by reciprocative motions of the piston 2, and different color inks and a recordability enhancing liquid are allowed to flow correspondingly.
