Title: Forming method for dual type diffraction grating
Inventor: SUMI TAKESHI
IPC: G02B5/18
Filed: 1988-06-28
Abstract: PURPOSE:To eliminate a grating shift by making light incident on a 1st diffraction grating on the top surface of a substrate and a 2nd diffraction grating brought into contact with the reverse surface of the substrate, and performing detection by a photodetecting element on a photodetection plate and moving and adjusting the substrate and photodetection plate. CONSTITUTION:The 1st diffraction grating 14 is formed on the surface of the acryl substrate 12 and the 2nd diffraction grating 16 is duplicated on the top surface of an Ni stamper 15 as a stamper member. A monomer 17 as a photopolymerizing member is dripped on the surface of the 2nd diffraction grating 16 duplicated on the Ni stamper 15 to unite the acryl plate 12 with the duplicated Ni stamper 15 of the 2nd diffraction grating 16. While the acryl plate 12 and the light which is reflected by the 1st diffraction grating 14 and 2nd diffraction grating 16 is detected, the photodetection plate 19 equipped with three photodetecting elements A, B, and C are moved by a fine adjustment driving drive over a look at a power meter 20. Consequently, the grating deviation between the 1st diffraction grating 14 and 2nd diffraction grating 16 is easily corrected, so the operation time is shortened to improve the production efficiency more.

Title: Tracking controller
Inventor: YOSHIOKA HIROSHI
IPC: G11B21/10
Filed: 1984-07-31
Abstract: PURPOSE:To prevent a pickup from coming off a track by detecting it when a track error signal of a tracking means reaches an upper limit value or more to feed a slider of the pickup by each prescribed amount. CONSTITUTION:A part of the transmitted light of a polarized beam splitter 8 is received by track error detecting photodetectors 13, 14, the remaining light is received by focus detecting photodetectors 15, 16 to detect a shift to a track 11. An output signal of a differential amplifier 25 changes with a shift between the pickup and the track 11 on an optomagnetic disc 7 and given to an upper/ lower limit comparator 27. The upper/lower limit comparator 27 gives an output signal until a tack error signal reaches the lower voltage when the signal level becomes an upper limit voltage of feed a slider 17 and does not give an output signal until the voltage reaches again the upper limit voltage when the level of the error signal is 0V to stop the slider 17. Thus, the pickup does not come off the track.

IPC: G02B6/13
Filed: 1994-06-20
Abstract: PURPOSE:To provide a quartz corner mirror waveguide from which a factor for scattering loss of light is eliminated by eliminating ruggedness on a reflection surface and a process for producing this waveguide. CONSTITUTION:A lower clad layer of quartz glass is formed on a substrate and a core layer of quartz glass is formed on this lower clad layer, The lower clad layer and the core clad layer form bent waveguides 2 of prescribed patterns and an upper clad layer 17 of quartz glass is so formed as to embed the bent waveguides 2 of the prescribed patterns. The reflection surfaces 3A are formed near the corner parts 2A of the bent waveguides 2, by which this quartz glass corner mirror structure is obtd. Waveguide corner surfaces 2B which are parallel with the reflection surfaces 3A and have prescribed intervals are formed in the corner parts 2A of the bent waveguides 2 having the prescribed patterns. Since the core layer is not directly exposed on the reflection surfaces 3A, the differences in level of the ruggedness by the etching treatment of the core layers and the clad layers do not exist on the reflection surfaces 3A and consequently, the scattering loss in the reflection parts is lessened.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To provide the character processor which makes it easy to prepare framed characters and a document. SOLUTION: Character information is inputted and stored in a buffer. The length of a character string when characters of specific size are generated based on the character information in the buffer is detected (S3) and it is decided whether the detected character string length exceeds the maximum width of a frame (S4); when the maximum width is not exceeded, it is decided whether or not the width of a current frame is exceeded (S5) and when not, the characters of the specific size based upon the character information in the buffer are put in the frame (S7). When the width is exceeded in S5, the width of the frame is expanded according to the character string length and the characters of the specific size are put in the frame as mentioned above (S7).  When the maximum width is exceeded in S4, the frame is expanded to its maximum width (S8), character size is calculated (S9), and the characters of calculated size based upon the character information in the buffer is put in the frame (S7).

Title: Bus error processing system
Inventor: MARUYAMA TAKASHI
IPC: G06F13/00
Filed: 1988-06-29
Abstract: PURPOSE:To heighten the reliability of a processing for a bus error due to a prescribed bus master module other than a central processing unit by designating the bus error due to the bus master module as an exceptional processing factor proper to the central processing unit. CONSTITUTION:When an exceptional processing request for the bus error of a direct memory access control DMAC2 is issued to a CPU1 by asserting a bus error processing request signal BETREQ, the CPU1 accepts the exceptional processing request directly, and after preserving a state, shifts an operation to the execution of a service program immediately without performing the setting and the change of an interruption mask bit. Therefore, the CPU1 starts the execution of the service program for the bus error of the DMAC2 even while it executes another exceptional processing or interruption processing. In such a way, it is possible to shorten a time from the issuing of a bus error exceptional request to the start of the execution of the service program compared with a case to respond by the interruption processing, and to improve the reliability of a system operation.
