Title: Rotary polygon mirror and manufacture method therefor
Inventor: KATO HIROAKI
IPC: G02B5/09
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To efficiently manufacture a rotary polygon mirror for keeping required accuracy even by simple manufacture processes by providing a reflection surface part for which a mirror finishing processing is performed to respective reflection surfaces in a state where the plural reflection surfaces are extended in a plane shape. SOLUTION: A resin molding 10 provided with the required reflection surfaces 12 of 6 or 8 surfaces or the like around a hub 13 is molded in an extended state. The reflection surfaces 12 and the hub 13 are connected by a bendable connection part 14. Then, the respective reflection surfaces 12 of the obtained molding 10 are made to face a vapor deposition source VE in the extended state and the vapor deposition of a reflection coating film is simultaneously executed to the respective reflection surfaces 12. That is, the need of performing the vapor deposition while rotating the plural moldings 10 is eliminated, the reflection surfaces 12 are turned to the vapor deposition source VE and the vapor deposition is simultaneously performed to the respective surfaces 12.  Thus, since a mirror finishing processing process is simplified, processing time is shortened, an assembly process is simplified as well and assembly man-hour is reduced.

Title: Apparatus for positioning semiconductor wafer
Inventor: TAKAHASHI KAZUO
IPC: H01L21/68
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To insure reliable positioning, by calculating a center of a wafer with the wafer moved in a first direction, detecting an end of the wafer in a second direction by a pair of sensors to calculate the center of the wafer, then rotating the wafer around a second rotation center, and detecting a periphery of the wafer by the sensors to calculate the center of the wafer. SOLUTION: A wafer is transferred in an X-axis direction and passed between optical length measuring devices 5, 6 to obtain peripheral position data d1, d2 of a diameter parts of the wafer. When the diameter part does not overlap with an orientation flat or a V notch, a diameter D of the wafer and a shift (y) between a center position O of the wafer on a robot hand and a rotation center P of a rotary table 4 are calculated. The wafer is displaced on the rotary table 4 by the robot hand to eliminate the shift (y), and further whether the center position O of the wafer coincides with the rotation center P of the rotary, table 4 is checked. Thus, the wafer can be reliably positioned.

Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To substantially enhance luminescent intensity by cracking a binder by means of baking a substrate applied with phosphor paste containing a binder in the atmosphere of argon or noble gas mainly containing argon. SOLUTION: Phosphor paste containing a binder is applied on a substrate, glass paste having a low fusing point and containing a binder is applied on the substrate, the binder is cracked by baking the substrate applied in the atmosphere of argon or noble gas containing mainly argon, a pair of substrates containing the baked substrate are bonded together with both substrates facing each other at a designated interval and are sealed in a mixed gas of argon and hydrogen. Luminescent intensity is enhanced by suppressing deterioration of the phosphor produced in a process to crack the binder of the applied layer and a process to heat and seal a front substrate and a back substrate. The binder is completely cracked by using an acrylic resin for the binder, in order to suppress lowering of luminance of a phosphor layer.  Stable sealing by glass having a low fusing point is carried out, by setting oxygen concentration at 5-50%.

Title: Manufacture of semiconductor
Inventor: HIGUCHI YUKIO
IPC: H01L21/301
Filed: 1986-09-30
Abstract: PURPOSE:To prevent the generation of cracks when a wafer is diced, by forming fine recessed and projecting parts on surfaces of scribe streets so that the scribe streets are satinized. CONSTITUTION:Minute recessed and projecting parts are formed on scribe streets 8 which bound elements of a semiconductor wafer by a plasma etching method or the like in a wafer process so that the wafer is satinized, and cutting grooves 6 are formed on the semiconductor wafer by a dicing saw or the like in order to separate this wafer into individual elements. Because the scribe streets 8 are finely recessed and projected to satinize, residual distortion occurs, for example, in the recessed parts formed by satinization. Therefore, even if fragments 7 are generated when the wafer is cut, the cracks stay in the recessed part and do not advance to a diffusion layer 3 and an oxidizing film 4, so that characteristic deterioration can be prevented.

In the controller 25, laser detection is recognized with the detection signal from the detection signal reception part 21, and the detection angle signal of a gun turret reference is indicated on an indicator 27 from a detection angle signal of the car body reference to which detection is performed and the gun present angle.  Even when the gun is turned, the detection angle signal is corrected and indicated from the gun present angle to a detection angle of the gun reference. Further, provided an attitude angle of the car body is detected with an attitude detector, a target is prevented from being lost even when the car body is moved.
