Title: POROUS SUPER ABRASIVE GRAIN THIN BLADE CUTTING WHEEL CONTAINING TiC COAT SUPER ABRASIVE GRAIN
Inventor: YAMADORI KAZUHIKO
IPC: B24D3/10
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To improve the discharge capacity of chips, the cutting quality, the efficiency, and the precision, and elongate the life by setting the thickness of a coat, the mean grain size of super abrasive grain, and the porosity of the super abrasive grain to prescribed values respectively. SOLUTION: A general thin-film forming means can be used to coat super abrasive grain 2 with TiC coat 5. W powder, for example, is used for bonding the super abrasive grains 2 coated with TiC coat 5 mutually. Mixture formed by uniformly mixing the coated abrasive grains 2 with the W powder fills a metal mold, is heated, and pressurized so that WC is formed in contact parts of the grains, dispersed, and bonded. The numerical range of the thickness of the TiC coat 5 is prescribed from 0.1 μm, or the necessity minimum for the metallic bond to the maximum 10 μm because of the relation between the grain size of the super abrasive grain 2 and the bonding force. The mean grain size of the super abrasive grain 2 is prescribed to 2-50 μm, the grain size range frequently used for a thin blade cutting wheel for the precise cutting. The porosity is set to 1-40 vol.%.

Filed: 1994-05-12
Abstract: PURPOSE:To obtain a restored image of high picture quality in a short time without performing the repeating processing for interpolation at the decoding side by multiplexing the pixel information which is sampled from the input image signal at a prescribed interval to the information on the feature points and then coding these multiplexed information. CONSTITUTION:A filter coefficient S2 is sampled by a subsampler 41 at a prescribed interval so that a sample coefficient S20 is obtained and sent to a selection multiplexing circuit 42. The circuit 42 multiplexes a quantization coefficient S3 and the coordinates of a feature point set when a selection signal 4 is equal to 1. Then the circuit 42 multiplexes the coefficient S20 to output it as a feature point signal S21.

Filed: 1982-07-15
Abstract: PURPOSE:To set the optimum exposure conditions capable of estimating the pattern size of a mask only by measuring illuminance of size recognition patterns, by inserting monitoring patterns into the wafer or the mask to be exposed at the time of transfer exposure using the optical mask. CONSTITUTION:Illuminance is examined by applying a probe for measuring light source illuminance to the size recognition patterns 2 at the contact exposure of the wafer. When the optical mask pattern is formed as designed, the patterns 2 is adjusted so as to form 50% light to dark ratio and the measured illuminance of the patterns 2 is set to 1/2 of the illuminance of the light source. When the patterns 2 are 2mm. squares arranged like a grid, and the pattern size deviates by 0.1mum, the light to dark ratio increases or decreases by about 10%, and the exposure conditions can be decided exactly and easily by graphically expressing the relationship between the illuminance to be measured and the size. Accordingly, the size of the actual pattern 1 of the present optical mask can be estimated only by measuring the illuminance of the patterns 2 during the contact exposure and the optimum exposure conditions can be decided.

IPC: F02D1/04
Filed: 1995-05-23
Abstract: PURPOSE: To reconcile the prevention of an excess increase from a proper value of low speed, idling speed of a diesel engine and the improvement of starting performance. CONSTITUTION: A base end 9a of a starting spring 9 is connected to a governor level 7, and in a low-speed setting state that this governor lever 7 is set to a low-speed position (low), the initial tension of this starting spring 9 is set into weakness.
