Title: Manufacture of semiconductor device
Inventor: SUGAI TOSHIYUKI
IPC: H01L29/808
Filed: 1992-01-13
Abstract: PURPOSE:To make a pinch-off voltage of a J-FET having an epitaxial layer uniform in one semiconductor wafer surface. CONSTITUTION:The method for manufacturing a semiconductor device comprises the steps of measuring, after a second conductivity type epitaxial layer 11 is grown on a first conductivity type semiconductor substrate 12, a distribution of a thickness of the epitaxial layer in a semiconductor wafer surface, and ion implanting first conductivity type impurities in the epitaxial layer. In this case, its ion implantation scanning speed is altered corresponding to a distribution of a thickness of the epitaxial layer, thereby altering the implanting amount in the wafer.

Title: Electrophotographic toner
Inventor: NAKATSU KIYOBUMI
IPC: G03G9/08
Filed: 1995-01-12
Abstract: PURPOSE: To surely remove an oxidized surface layer by grinding and to form a satisfactory image by using abrasive particles contg. calcium carbonate and having a specified Mohs hardness and a specified average particle diameter on volume basis. CONSTITUTION: Abrasive particles contg. at least calcium carbonate and having a Mohs hardness of >=3.5 and 0.1-10μm average particle diameter on volume basis and a silica additive are added by 0.1-3 pts.wt., in total, to 100 pts.wt. toner particles. The abrasive particles are blended with the silica additive preferably in a weight ratio of 0.1:10 to 3:10. Powdered marble is especially suitable for use as the abrasive particles. Since calcium carbonate as the principal component of the abrasive particles has low volume resistivity and no electrostatic chargeability, when the abrasive particles are used in combination with the silica additive, the quantity of electric charges on the resultant toner is easily controlled and the scattering of the toner is not caused.  In the case where the Mohs hardness of the abrasive particles is <3.5, an oxidized surface layer cannot surely be removed by grinding.

Abstract: PURPOSE: To enable reliable detection of step-out by performing the detection of the step-out on the basis of rectangular wave corresponding to two times of electric angle for determining to be step-out from the pulse obtained in accordance with the rotation of the generator and the motor.  
     CONSTITUTION: Upon the rotation of morot G and generator M, pulses having width corresponding to 90° of the electric angle are supplied from the projection detectors 7, 9 and converted by frequency dividers 12, 13 and 14, 15 into rectangular waves having width corresponding to 360° of electric angle. When the generator G is synchronised with the motor M, there is phase difference of 180° between the differenciating pulse produced at the rising of rectangular wave outputed from frequency dividing circuit 15 and the rectangular wave outputed from frequncy dividing circuit 13 thereby relay 19 doesn't function. When the motor M steps out to shift the motor M more than 180° from the generator G, the differenciating pulse from the differenciating circuit 16 is overlapped with the rectangular wave outputed from the frequency dividing circuit 13, to set the flipflop circuit 18 thus to function the relay 19.

Title: Manufacture of thick-film capacitor
Inventor: MIYAMOTO AKIRA
IPC: H01G4/33
Filed: 1988-01-13
Abstract: PURPOSE:To obtain a thick-film capacitor having excellent reliability and high performance by equalizing the thickness of a dielectric layer extending over the whole region without forming cavities on the insides and recesses in the surfaces to a lower electrode and the dielectric layer. CONSTITUTION:Conductor paste printed to a lower electrode pattern on a substrate 1 is baked in an atmosphere, pressure of which extends over 1 approximately Torr or less, thus shaping a lower electrode 3. Dielectric paste printed to a dielectric pattern superposed to the electrode 3 is baked in the atmosphere, pressure of which extends over approximately 1Torr or less, thus forming a dielectric layer 4. Conductor paste printed to an upper electrode pattern superposed to the dielectric layer 4 is baked, thus shaping an upper electrode 5. Consequently, a gas generated from the inside of paste in a baking process is easy to escape to the outside of paste. No cavity and recess is formed in the electrode 3 and the dielectric layer 4. The thickness of the dielectric layer 4 is equalized extending over the whole region. Accordingly, a thick-film capacitor having excellent reliability and high performance is acquired.
