Title: Eddy current type flow velocity meter
Inventor: GOTOU SHIGERU
IPC: G01F1/56
Filed: 1981-05-22
Abstract: PURPOSE:To measure the flow velocity of various conductive fluids at a high accuracy free from effect of zero-variations with temperature changes by deriving a temperature compensating signal from output signals of a plurality of detection coils. CONSTITUTION:A.C. signals are applied along the flow F of a conductive fluid  to be measured to a detection section 10 provided with an exciting coil WEX and detection coils WD1 and WD1  therenear. This detection section 10 is used to determine the flow velocity of the fluid being measured based on signals of a difference between output signals of the detection coils. In this case, a signal e7 for temperature compensating corresponding to a temperature coefficient of a signal e4 of a difference between the output signals of the detection coils is obtained from a change in a signal e3 of the sum of the output signals of the detection coils. This signal e7 is used to effect temperature compensation for the signal e4.

Title: Method for controlling injection of ammonia to denitrator
Inventor: SAITO HIDEKI
IPC: B01D53/74
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To keep the NOx concn. at the outlet of the denitrator below a specified value at all times and to nullify leaked ammonia by obtaining an appropriate injection of ammonia. SOLUTION: The amt. of ammonia to be adsorbed and injected is obtained by solving the reverse model of the dynamic characteristics of the denitration and adsorption reactions by the use of the flow rate and temp. of the waste gas, the NOx concn. at the inlet and the desired NOx concn. at the outlet. The estimated NOx concn. at the outlet is calculated by simulation by using the flow rate and temp. of the waste gas and the NOx concn. at the inlet, the obtained estimated NOx concn. at the outlet is compared with the desired NOx concn. at the outlet to obtain the correction, and the corrected amt. of ammonia to be injected is obtained from the correction.  The sum of the calculated amt. of ammonia to be injected obtained by solving the reverse model and the corrected amt. of ammonia to be injected obtained by the calculation by simulation is used in the FF signal of the ammonia injection, and the injection of ammonia into the denitrator is feedforward-controlled by using the signal.

Title: Snow melting, heat accumulating and cooling apparatus according to latent heat exchange system
Inventor: HATSUTORI MASARU
IPC: F24F5/00
Filed: 1980-06-09
Abstract: PURPOSE: To utilize energy efficiently by a method wherein the freezing latent heat in a heat accumulating water tank is used as a snow melting heat source in winter and the ice melting latent heat in the tank is used as a cooling source in summer.  
     CONSTITUTION: A snow melting cycle H is formed by opening check valves 9 and 10 and by closing check valves 11 and 12 in winter. A high temperature and high pressure coolant gas from a compressor 3 melts snow in a snow melting heat exchanger 4 while the gas is cooled and condensed to become a liquid. The condensed coolant liquid is stored in a liquid vessel 5, introduced into a main heat exchanger 2 via an expansion valve 6 and evaporates as it conducts heat to the water in the  heat accumulating water tank 1. Thus, by repeating the above cycle, the water in  the water tank 1 freezes. On the other hand, a cooling cycle R is formed by closing  the check valves 9 and 10 and by opening the check valves 11 and 12 in summer.  When a liquid pipe 7 is operated, the water cooled by the ice in the water tank 1 is  circulated through a heat exchanger 8 for cooling.

Abstract: PURPOSE:To cause the direction of a micro crack generated in the surface of a part to be bonded to extend in parallel to the direction of a tensile stress generated on the surface of the part to be bonded after bonding with a metallic material and to increase the strength of a joint part, by a method wherein the part to be bonded of a ceramic member is first axially polished, and the part to be bonded is then cast by using a metallic material. CONSTITUTION:In a first process, a part 1a to be bonded of a ceramic member 1 is axially polished by a grinding stone 3. The direction of a micro crack generated in the surface of the part 1a to be bonded of the ceramic member 1 is extended in parallel to the axis of the part 1a to be bonded. As a result, in a second process, the direction of a tensile stress generated on the surface of the part 1a to be bonded of the ceramic member 1 after a metallic material 2 is cast in the part 1a to be bonded to bond them together is extended in parallel to the direction of a micro crack generated on the surface of the part 1a to be bonded.
