Abstract: PURPOSE:To eliminate any troubles due to a photomask making mechanical systems light-weight for facilitating the enlargement of a substrate by a method wherein a rapid (less than musec) ON/OFF control mechanism of laser beams, an iris diaphragm mechanism of laser beams and a scanning mechanism of laser beams are provided to control said mechanisms for making selective irradiation feasible. CONSTITUTION:A substrate 17 is linearly irradiated with visible laser beams 18 emitted from a semiconductor laser 11 (main scanning). Consequently, the whole surface of the substrate 17 can be irradiated with laser beams 21 by shifting an optical system 19 composed of the semiconductor laser 11, iris diaphragm mechanisms 13 (optical unit) 14 (ftheta lens) and a rotary polygon mirror 15 in parallel with the substrate 17 (sub scanning). Thus, synchronous signals 23, 24, 25 are transmitted from a control signal transmission circuit 22 respectively to a power supply 12, the rotary polygon mirror 15 and the shifting mechanism 20 of the optical system 19 so that the substrate 17 may be selectively irradiated with the laser beams 21 to transfer any specified mask pattern to a sliver chloride layer on the substrate 17. Through these procedures, the substrate 17 can be enlarged easily further enabling a photomask to be eliminated.

Abstract: PURPOSE:To reduce the disconnection of a gate electrode and improve yield, by forming the oxide insulating film of an active layer which is oxidized until the bottom surface, on the outer periphery of the active layer of each thin film transistor. CONSTITUTION:A ground film 11 of silicon oxide is formed on a substrate 10. An amorphous silicon film 12 is formed by a CVD method.

Title: Vcm coil
Inventor: NAKAMURA SHIGEO
IPC: H02K33/18
Filed: 1988-09-14
Abstract: PURPOSE:To make a coil compact, to facilitate assembling and to enhance reliability by independently forming the coil and a bobbin for supporting the coil, providing grooves at the attaching surface of the bobbin, and bonding the bobbin. CONSTITUTION:When a coil 5 and a bobbin 1 are bonded, the amount of a bonding agent 6 is less, and the light-weight can be implemented. Since the outer size of the coil 5 intactly becomes the size of a VCM(voice coil motor) coil, the mounting space becomes small. Grooves 2 are provided in the attaching surface of the bobbin 1 and the bonding agent 6 is stored. Thus the adhesive strength is improved. For example, when the coil 5 is bonded to the bobbin 1 comprising a glass-incorporated epoxy resin with the epoxy based bonding agent 6, the adhesive strength is made twice or more by providing the grooves 2. Grooves 4 are further provided in the bonding surface of the bobbin 1 with the coil 5, and the lead-out wires of the coil 5 are made to pass in the grooves 4. Therefore, the lead-out wires are not held between the coil 5 and the bobbin 1, and the coil 5 is not floated from the bobbin 1.

Abstract: PURPOSE:To estimate properly plane vibration and plane inclination by utilizing the difference between drive signals of focus control signals in two tracks in a focus drive system having hysteresis. CONSTITUTION:A disk 1 is showing plane vibration downward from the inner circumference direction to the outer circumference direction. Optical heads 2 and 3 detect the N-numbered and the N+3,000 numbered tracks. A focus is always set to ON. The relation of DELTAl=A+K.I is valid between a drive current I and the moving amount of a lens DELTAl. It is assumed that distances in the horizontal direction of the N-numbered and the N+3,000-numbered tracks are L. A DELTAlN at the time of detecting the N-numbered track is DELTAlN=A+K.IN, a DELTAlN+3,000 at the time of detecting the N+3,000-numbered track is DELTAl+3,000=A+K.IN+3,000, and a change in plane in the vertical direction for this time is DELTAlN-DELTAlN+3,000= K. (IN-IN+3,000). As a result, plane inclination for this time can be obtained by tan<-1>(DELTAlN-DELTAlN+3,000)/L.
