The margin width T shall be below 0.05mm with the machine material prevented from fusion deposition, and the run-off angle alpha of No.1 secondary taking surface 17 be 1-5 deg. to prevent secondary touch with possibility of high feed, and the width of No.1 run-off surface 17 is added to the margin width T with the run-in width W ranging 0.05mm thru 0.5mm so as to prevent drop of the cutter tip strength, which accomplishes prolonged lifetime of the tool without enlarging the wear width relative to the wear depth. The run-off angle beta of No.2 secondary taking surface 18 shall be 8-20 deg. to provide sufficient rigidity of the cutter tip without enlarging the wear width relative to the wear depth. Accordingly the cutter tip strength is increased to cause decrease of chippings as long as an end mill is concerned, while there is a certain wear and vibration so far as a reamer is concerned, however with favorable points involved.

Filed: 1990-06-07
Abstract: PURPOSE:To make it possible to detect the sizes and the positions of a plurality of defects accurately at the same time by detecting all peak values of a plurality of echo signals, and storing the output values of corresponding address counters. CONSTITUTION:Pulses are outputted from a transmitting part 3 based on the trigger signal from a timing circuit 8. A probe 2 is excited, and ultrasonic waves are emitted. The ultrasonic waves are reflected from defects and the like. As a result, the echo signal is outputted from a receiving part 4. The echo signals sequentially undergo A/D conversion in an A/D converter 5. The results are outputted to a wave form memory 6 and a gate circuit 16. The data are stored in the memory 6. Meanwhile, a waveform judging circuit 19h outputs a memory executing signal to a memory control circuit 19i at the time point when the new data which are inputted from a converter 5 are once increased and decreased. At this time, the circuit 19i outputs the signal to a memory 19k and also outputs the storage execution signal to the memory 19j at the same time. The value of an address counter 7 indicating the position of the peak value is taken out of a latch circuit 19a and stored.

Title: Denitration catalyst
Inventor: KOBAYASHI TAKAFURU
IPC: B01J33/00
Filed: 1986-06-27
Abstract: PURPOSE:To prevent the adhesion of the solid component in exhaust gas and to enhance catalytic durability, by forming a coating layer having micropores communicating with the surface of a denitration catalyst but substantially having no oxidizing capacity to the surface of the denitration catalyst. CONSTITUTION:A denitration catalyst has a coating layer having micropores with a pore size of about 20-30Angstrom  formed to the surface thereof. The micropores communicate with those being the active spots of the denitration catalyst. Said micropores allows no solid component to pass but permits gaseous components such as NOx, SOx or the like to pass and, therefore, the active metal M of the catalyst is contacted with gaseous NH3 and NOx through the micropores of the coating layer to allow denitration reaction to advance. However, the solid component remains of the surface of the coating layer and SOx is diffused throughout the micropores of the coating layer.
