Title: Production of abrasive grain of abrasive material
Inventor: HASEGAWA HIKARI
IPC: B24B37/00
Filed: 1988-09-30
Abstract: PURPOSE:To obtain tough abrasive grains by coating alumina particles contg. water of crystallization limited to a prescribed amt. or less with fine powder of a specified oxide or suboxide and by heating the coated particles. CONSTITUTION:Alumina gel is dried or calcined to obtain alumina particles contg. water of crystallization limited to <=30% of the amt. of Al2O3. The alumina particles are coated with fine powder of at least one of salts of Cr, Ti, Fe, V, Mg, Ga and Rh or impregnated with a soln. of at least one of the salts and heated to 1,150-1,400 deg.C. By this heating, the element forms a solid soln. In the alumina and tough abrasive grains of alumina are obtd. The diffusion coefft. of the element relates to a temp. exponentially and the formation of the solid soln. decelerates remarkably at <1,150 deg.C. When the element has a large ionic radius, it forms no solid soln. at <1,150 deg.C because of insufficient activation energy. The grain size of the abrasive grains is made excessively large at >1,400 deg.C. The pref. heating time is about <1.5hr. The grain size of the abrasive grains is made excessively large by heating for >=1.5hr.

Title: Analog-digital converter
Inventor: RYU KAZUO
IPC: H03M1/46
Filed: 1984-11-22
Abstract: PURPOSE:To form an A/D converter which converts even an analog input signal coming from a large signal source resistance with high accuracy by decreasing a rush current generated in sampling the analog input signal. CONSTITUTION:When it is supposed that an A/D converter is actuated by a unipolar power supply and a reference voltage VREF of a D/A converter 8 is equal to a power supply voltage, accurate comparison cannot be attained up to the LSB (least significant bit), because a common mode input voltage range of a differential amplifier is narrower in general than the range from zero to the power supply voltage when the analog input signal is zero or equal to the VREF. Then in the conversion within the common mode input voltage range of the differential amplifier 13, the analog input signal and the output signal of the D/A converter 8 are compared directly by the differential amplifier 13 and in the conversion of the analog input signal at the outside of the common mode input voltage range of the differential amplifier 13, a chopper stabilizing system as in a conventional example is adopted. Then the rush current is suppressed to 1/4 of the conventional example.

Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To enable a container to be squashed at the time of disposal of the used container by constituting a body of a variable wall face and an invariable wall part, wherein the variable wall face is connected to an invariable wall face via a rib and the variable wall face reversely rotates with the rib as an axis. SOLUTION: A container is pressed and squashed from the forward and backward sides at the time of disposal of the used container. When a variable flat wall 18a is pressed, the wall 18a rotates with a longitudinal rib 15a as an axis, while a variable side wall 19a rotates together with a longitudinal rib 16b as an axis. In addition, an upper gradient wall 20a rotates with an upper lateral rib 17a as an axis, and a lower gradient wall 21a rotates with a lower lateral rib 24a as an axis. At this time, the variable flat wall 18a is bent inward in the container to insure rotation of the variable side wall 19a, while center parts of the variable flat wall 18a and the variable side wall 19a are bent inward in a longitudinal direction to facilitate rotation of the upper and lower gradient walls 20a, 21a. Thus a volume of plastic wastes can be reduced, thereby improving transportation efficiency of the wastes.
