Title: Heat treatment method for compound semiconductor substrate
Inventor: NAKAGAWA YASUHITO
IPC: H01L21/324
Filed: 1989-04-28
Abstract: PURPOSE:To control thermal dissociation of a constituent element and external diffusion of implanted impurity atoms with good reproducibility by a method wherein a heat treatment is executed in a state that an ion-implanted face of a silicon substrate into which ions of an element with a high vapor pressure have been implanted and an ion-implanted face of a compound semiconductor substrate have been placed so that they face each other. CONSTITUTION:When a GaAs substrate 11 into which, e.g. <28>Si<+> ions have been implanted is heat-treated, the GaAs substrate 11 is placed on an Si susceptor 13 in such a way that a <28>Si<+>-implanted face 14 is faced upward. Then, an Si substrate 12 is placed on the GaAs substrate 11 in such a way that a <75>As<+>-implanted face 15 is faced downward. In this state, an infrared beam of a halogen lamp is irradiated from the upper part of the Si substrate 12; thereby, the GaAs substrate 11 is annealed. In this manner, when the GaAs substrate 11 is heat-treated by using the Si substrate 12 into which <75>As<+> ions have been implanted, a pressure of As is applied from the Si substrate 12 to the GaAs substrate 11; thereby, thermal dissociation of As as a constituent element with a high vapor pressure and external diffusion of Si as implanted impurity atoms are reduced.

Title: Liquid crystal driving device
Inventor: HORI YOSHIHIKO
IPC: G09G3/36
Filed: 1993-05-13
Abstract: PURPOSE:To prevent the generation of disturbance on a screen in a non-interlace scanning mode by suppressing the input of an unwanted line selecting signal to a liquid crystal display panel near the generation time of a clock signal pulse in the non-interlace scanning mode. CONSTITUTION:In the non-interlace scanning mode of a liquid crystal display device, a false signal is imparted to a node EVEN/the inverse of ODD at the time of selecting an odd line and a true signal is imparted thereto at the time of selecting an even line. A signal to be turned to false in a period before and after a clock pulse is imparted to a node OUTPUT/CONTROL. When a node STAR is turned to true and the initial pulse is imparted to a node CLOCK, a line G1 on a liquid crystal panel is selected because the node EVEN/ the inverse of ODD is false. When the node EVEN/the inverse of ODD is turned to true, a line G2 is selected by an AND gate 6. Since an output supressing signal temporarity inputted to the node OUTPUT/CONTROL is turned to false at the time, an abnormal selection signal is not generated on the line G1.

Title: Press, and manufacture of pressed article
Inventor: NAKAJIMA SUEKAZU
IPC: B30B1/18
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To increase the pressing precision by reducing the mutual interference between a plurality of sets of dies connected to a common frame. SOLUTION: A plurality of sets (e.g. two sets) of dies are driven by servo motors 6a, 6b. The servo motors 6a, 6b are individually controlled by servo amplifiers 8a, 8b, respectively. A control part of the servo amplifier 8a calculates the current I so that the measured value X at the rotational position of the servo motor 6a follows the indicated value X0 transmitted from a CPU through a pulse generator 9. A torque detection and control part 25 transmits the torque to the servo motor 6a through the current amplifier 26 after limiting the calculated current I so that the torque does not exceed the limit value of the torque to be transmitted from the CPU through a DA converter 12. When the torque of the servo motor 6a reaches the limit value after the dies are brought into contact with each other, the indicated value X0 is rapidly advanced in the die-closing direction.
