Title: Manufacture of silicon carbide member
Inventor: MATSUMOTO FUKUJI
IPC: C04B35/565
Filed: 1991-07-01
Abstract: PURPOSE:To obtain a silicon carbide member being suitable for heat processing of a semiconductor and having extremely high cleanliness in a surface by specifying iron content of powdery abrasive grains for blast processing on a surface of a silicon carbide sintered body. CONSTITUTION:For example, a silicon carbide powder (GC grade, number 60) on the market is immersed in a solution formed by mixing HF, HNO3 and H2O at a ratio of 1:1:1 in vol. and processed for cleaning. After extracting acids, the powder is enough washed with pure water to obtain high purity silicon carbide powdery abrasive grains having <=50ppm iron content. When the surface of the silicon carbide sintered body is processed by blast with the silicon carbide powdery abrasive grains having thus reduced iron content, contamination caused by iron brought out from abrasive grains is prevented and the silicon carbide member being extremely high in cleanliness of the surface is obtained.

Title: Dry desulfurizing method
Inventor: TSUGAWA HIROTSUGU
IPC: B01D53/81
Filed: 1984-09-10
Abstract: PURPOSE:To desulfurize in an adsorption tower at a temp. below the dew point of the acid by adsorbing and removing previously SO3 in a desulfurizing method of waste gas contg. sulfur oxides. CONSTITUTION:Powdery activated carbon is blown into waste gas in a SO3 remover 3 to adsorb and remove SO3, and the waste gas removed from SO3 is supplied into an adsorption tower 5 wherein a carbonaceous material is packed and moved and desulfurized. Namely, since SO3 is adsorbed and removed by blowing in powdery activated carbon before the waste gas is introduced into the adsorption tower 5, the SO3 concn. in the waste gas introduced into the adsorption tower 5 is decreased. Consequently, sulfuric acid is not formed due to the dew point of the acid in the adsorption tower 5 even at low temps. and the desulfurization efficiency is also improved.

Filed: 1980-12-29
Abstract: PURPOSE: To assurely supply chip-like parts by providing a parts container, which is almost conical at the inner surface of the bottom and is provided with a leading pipe inserted into the bottom portion thereof, which is moved up and down relatively to the container, and with a moving element movable to the bottom portion thereof.  
     CONSTITUTION: When a hopper 2 storing a lot of chip-like parts 1 therein is moved vertically, the parts 1 in the hopper 2 are caught by a leading pipe 5 inserted into the bottom portion of the hopper 2, with those aligned vertically. The caught parts 1 are guided to a parts supply path 11 disposed in a support block 10 and once stopped by a shutter 14 advancing into a slit 12 positioned below the path 11. After that, the retreat of the shutter 14 and advance of a retaining pin 17 force the lowermost parts to be fed out. Since a moving element 17 inserted into the bottom portion of the hopper 2 is adapted to move up and down relatively synchronously with vertical motions of the hopper 2, the parts 1 are prevented from adhering in layers at the described portion, which results in that the parts can be assuredly supplied to the last one.

IPC: H01L21/027
Filed: 1990-07-18
Abstract: PURPOSE:To form a pattern having no proximity effect by a method wherein the image of a first rectangular aperture is drawn while it is being moved continuously and in a definite direction on an arbitrary pattern of a second aperture. CONSTITUTION:Regarding a pattern 24, an aperture pattern is arranged by setting a margin, on the left side, by 130mum which is a little larger than 125mum projected by a first rectangular aperture. Regarding a pattern 23, a margin is set on the right side. When not a definite voltage value but a voltage shown by a line (b') is applied to an electrostatic deflector 4, a transmission beam of the first rectangular aperture 2 is moved at a definite speed to the left direction from a part directly above the pattern 24 of a second aperture 6. When a drawing operation is executed in this state, an energy storage amount displays a leftward rise distribution. On the other hand, when a voltage shown by a line (a') is applied to the electrostatic deflector 4 in the same manner, the beam 16 formed by the first rectangular aperture 2 is moved at a definite speed to the right direction from a part directly above the pattern 23 of the second aperture. The energy stored inside a resist has a rightward rise tendency. When a drawing operation is executed in this manner, resist patterns 20 are obtained as designed.

IPC: G01R31/00
Filed: 1987-07-27
Abstract: PURPOSE:To discriminate the quality of cross talk, by comparing the absolute value of the difference between the first and second measured values with a prepared tolerant reference value. CONSTITUTION:The input terminal IN(ch1) of an amplifier circuit 1 is earthed to the ground and, at the point of time when the current flowing to a load resistor 3 becomes zero, the value of the voltage level meter 5 connected to the other amplifying circuit 2 read as the first measured value eA while the voltage of an external power source 4 is made variable. Next, voltage 6 insufficient to saturate the output of the amplifying circuit 1 is supplied as test voltage. At this time, the value of the voltage level meter 5 connected to the other amplifying circuit 2 is read as the second measured value eB. Subsequently, the difference between the first and second measured values eA, eB is calculated and, by comparing ¦eA-eB¦ with the tolerant reference value (e) preliminarily calculated and prepared at every IC amplifier, the IC amplifier is judged to be good when the measured data is within a torelant range and judged to be inferior if said data exceeds the tolerant range. By this method, the quality of cross talk can be discriminated.
