Title: Method for processing hot water supply finish time for hot water supplier equipped with instant hot water function
Inventor: YAMAGUCHI HIDEKI
IPC: F24H1/10
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To contrive so that hot water high temperature or hot water at low temperature is not allowed to come out at redischarge of hot water by circulating the hot water within a circulation path by operating a circulation pump, after cooling the hot water within a heat exchanger to safe temperature by operating a blower at finish of hot water supply. SOLUTION: When the flow rate of the water flowing to a heat exchanger 3 after opening of a hot water supply plug 11 gets over the lowest working flow rate, a hot water supplier 1 starts the supply of hot water, and when it comes to the flow rate under the lowest working flow rate, the hot water supply plug 11 is closed to stop the supply of hot water, whereby it is returned to an instant hot water mode. In this way, the hot water within a circulation path 19 is circulated for thirty seconds by operating a circulation pump 21, after cooling the residual water at high temperature remaining in a heat exchanger 3 by a blowing fan 26 for a certain time at finish of hot water supply, thus the residual water within the circulation path 19 is circulated within a circulation path 19 in the direction of an arrow shown by a solid line so as to equalize the hot water temperature within the circulation path 19. Hereby, this system can prevent the hot water at high temperature or hot water at low temperature from being let out at redischarge of hot water.

Title: Both side welding method for horizontal fillet part
Inventor: SHIMATANI AKIMITSU
IPC: B23K9/14
Filed: 1980-12-25
Abstract: PURPOSE: To improve the working efficiency of welding considerably by placing a rail-like member perpendicularly to a member to be welded which is disposed roughly horizontally, disposing two pieces of low angle welding jigs to both fillet parts thereof, and welding the members simultaneously.  
     CONSTITUTION: A rail-like member 22 is tack-welded perpendicularly on a member 21 to be welded which is disposed roughly horizontally, and two pieces of low angle welding jigs 1, 1' are disposed in the same direction along the horizontal fillet parts 23. The two jigs 1, 1' are connected to each other by means of two pieces of U-shaped connectors 10, and are fixed to the member 22. Next, coated electrodes 3 are grasped with welding torches 2, 2' respectively, and electricity is conducted simultaneously to both sides, thence welding is started. Stoppers 4 are set in the start positions. When welding progresses and the electrodes 3 are consumed to the preset length, the welding is stopped by the operation of the stoppers 4. Thereby, the possibility of cracking of the tack-welded part of the member 21 and the member 22 is eliminated.

Title: End code transmission/reception method in voice coding communication
Inventor: NAITO MASASHI
IPC: H04B14/04
Filed: 1992-06-19
Abstract: PURPOSE:To reduce mis-detection of an end code due to a bit error by differentiating a transmitting end code length from an end code length detected at a receiver side. CONSTITUTION:An end code length at the transmission is set to 1/N of a conventional system (N is an integral number by which end code length is 3-16 bits) and the end codes are continuously transmitted by number of multiple of N. Thus, the bit number of the entire end code to be transmitted is the same as a conventional entire bit number. On the other hand, a multiple of N of the end code length is used for one frame at the receiver side and the coincidence of the code is detected by shifting one code each. For example, each of end codes E(1), E(2)...E(30) is selected to be 5 bits each and in total 150 bits for 30 codes are transmitted. The receiver side takes the 50 bits for one frame the same as a conventional system and shifted in the unit of one code and the end code is detected. Thus, the coincidence is detected for the end code for each of 5 bits and mis-detection of the end code due to bit error is reduced.

Title: Induction heating cooker
Inventor: AOKI TETSUO
IPC: H05B6/12
Filed: 1992-07-13
Abstract: PURPOSE:To improve durability and convenience by integrally providing, by resin molding, a heat resisting flat top plate for placing a pan body which has a raised wall on the outer circumference and an integrally formed collar part suspended from the upper end; and an upper case having a frame part on the outer circumference. CONSTITUTION:A rib 16 is engagingly locked by a frame part 21 provided on an upper case 18 to prevent the slippage of a pan body 11 when moved. Since a hole part 15 is formed on the collar part 13 of the pan body 11, the temperatures of the rib 16 and a handle part 14 are suppressed low. Therefore, the possibility of the damage of the upper case 18 by heat or the erroneous burn at the time of attaching and removing the pan 11 is eliminated. Thus, since the pan body 11 is regulated by the frame part 21 if it is moved, safety is enhanced. Further, since the handle part 14 is situated on the lower end part of the pan body 11 to moderate heat conduction, convenience can be improved.

IPC: G02B6/24
Filed: 1987-07-24
Abstract: PURPOSE:To improve workability and safety and to obviate an increase in connection loss and the deterioration of strength by selecting the material of plastic clad layers so that the fusion connection of optical fiber can be executed without removing the core plastic clad layers of the optical fibers. CONSTITUTION:The plastic clad optical fiber which has a core 1 consisting of quartz and the plastic clad layer 2 consisting of a fluorine-contg. resin and having <=10% residue of thermal decomposition by thermogravimetry is selected. Protective layers 4 and buffer layers 3 of the optical fibers are removed and while the plastic clad layers 2 are held coated on the cores 1, the fusion connecting parts of the optical fibers are butted and heated. The need for removing the plastic clad layers 2 is thereby eliminated and the workability is improved. Since heat and solvents are not used, there is no danger in the operation and since the core surfaces are not flawed, the connection loss is not increased and the strength is not increased as well.
