Title: Optical master disk exposure device and its control method
Inventor: NISHIDA JUN
IPC: G11B7/085
Filed: 1995-05-31
Abstract: PURPOSE: To suppress the vibration of a slider of an exposure device exposing an optical master disk and to accurately move an objective lens on the slider at a constant speed. CONSTITUTION: An exposing beam 5 is converged by an objective lens 8 by means of an exposing optical system 6 provided on a slider 1. A piezoelectric element 11 finely adjusting the position of a first fine adjustable table 10 mounting the objective lens 8 is provided on a second adjustable table 9. An optical master disk 4 is arranged on a position opposed to the objective lens 8. A turntable 2 for rotating the optical master disk 4 is arranged. By moving the first fine adjustable table 10 by the same distance as the amplitude of vibration of the slider 1 in the reverse direction to the vibration direction, the vibration of the slider 1 is canceled and the objective lens 8 on the first fine adjustable table 10 is accurately moved at a constant speed at which the slider 1 aims. Then, the accuracy of a track pitch is not deteriorated.

Title: Epitaxial wafer manufacturing apparatus
Inventor: TAMURA TAKEO
IPC: H01L21/68
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To avoid epitaxial-layer drop problem. SOLUTION: A lift pin 10 is used to push up a wafer from a susceptor 6. The pin 10 is made of a material, which has a thermal conductivity of less than 128 W/m.K which is lower than that of the susceptor 6, and a head part 10b of the lift pin 10 is formed in a shape such that the head part 10b is snugly fitted into a through-hole 8 without any gap therebetween. During formation of an epitaxial layer, heat transmission toward the lower surface side of the susceptor 6 from an upper surface of the wafer W can be suppressed by the head part 10b and a led part 10a of the pin 10. The problem that the temperature of a zone P in the upper surface of the wafer W corresponding to the through-hole 8 being lower than that of the other zone, can be avoided, and thus an epitaxial-layer drop that an epitaxial layer formed in the zone P is thinner than the other zone, can be prevented.

Title: Tangential direction control system for tool axis
Inventor: SASAKI TAKAO
IPC: G05B19/4103
Filed: 1992-05-26
Abstract: PURPOSE:To control a tool so as to always direct it toward a tangential direction corresponding to the advancing direction. CONSTITUTION:A pulse distributing means 61 of a CNC 6 performs pulse distribution processing for designated coordinate values X and Y and controls the revolution of servo motors 3 and 4 by sending signals to the servo motors 3 and 4 corresponding to axial pulses DELTAX and DELTAY obtained as the result. In the case of circular arc interpolation, the pulse distributing means 61 sends the axial pulses DELTAX and DELTAY to a tangential direction calculating means 62. Based on those axial pulses DELTAX and DELTAY, the tangential direction calculating means 62 calculates an angle (tangential angle) theta formed by an advancing direction 111 of a tool 62 and a tangential direction 112 and outputs the tangential angle theta to a spindle motor 2. Since the spindle motor 2 is revolved just at the tangential angle theta, a blade face 220 of the tool 22 is controlled so as to be always directed toward the tangential direction 112 corresponding to the advancing direction 111.

IPC: H04N5/66
Filed: 1990-05-25
Abstract: PURPOSE:To increase a frame frequency of liquid crystal drive by outputting alternately a data of a most significant bit of a video data stored in a memory and a video data not through the memory for each 1/2 horizontal scanning period. CONSTITUTION:A memory M reads a data of a most significant bit of a video data E from an A/D converter 3. The read data by 1/2 field is read after 1/2 field and outputted to a shift register 15 as a 1-bit data Ec.

Title: Coplanar type antenna
Inventor: AOKI KATSUHIKO
IPC: H01Q13/10
Filed: 1988-05-30
Abstract: PURPOSE:To arrange the central conductor and ground conductor of a coplanar line on the same plane so as to form a planar antenna of one sheet of film only by using the coplanar line for the inputoutput terminal and extending the central conductor in the axial direction so as to form a slot antenna together with the central conductor. CONSTITUTION:The slot 2 of this antenna is formed of a slot line having an opened end and the electric field distribution of the slot becomes symmetrical with respect of the line B-B. Then a short-circuiting line 4 is provided so that the asymmetrical mode cannot be excited at a coplanar section. Therefore, when the total length L of the slot is set to L=lambda/2 (lambda:wavelength), the slot becomes a resonant state and standing waves are produced by the slot. As a result, the slot operates as an antenna like as a half-wave dipole. Moreover, the interval (l) between the center P of the slot and input terminal Q of the coplanar line is decided in accordance with the input impedance of a semiconductor element. As a result, the grounding plate of the coplanar line can be arranged perfectly on the same plane and the antenna formed by printing a pattern on the film can be obtained by not using a so called microwave base plate, but the extremely thin film.
