Title: Hologram scanner
Inventor: KANEKO YUTAKA
IPC: G02B5/32
Filed: 1979-08-07
Abstract: PURPOSE: To obviate fluctuating of the light intensity of a scanning beam on a scanning plane along with scanning by disposing a density filter having a predetermined density distribution within the deflecting region of a scanning beam.  
     CONSTITUTION: A density filter F is disposed in the polarizing region of scanning beam owing to the diffracted light produced by irradiating the reconstructing light B 01  to the hologram of a recording body 1 on a rotating cylinder. The density D of the density filter F is so set as to negate the fluctuations in the scanning beam intensity occurring in space frequency recording characteristics. This may be accomplished by placing, for example, a photographic plate in the position of the filter F, reconstructing the scanning beam by the reconstructing light B 01 , rotating the hologram recording body 1 at the same angular speed as that at the scanning and performing developing after exposing thereby providing the density filter. In an actual apparatus, the beam from a laser light source 100 is entered to the hologram recording body 1 via a reflecting mirror 101, a lens 102 and a stop 103 and the scanning beam SB thereof is passed through the filter F, thus in the state that its intensity is held maintained constant, it scans an original O.

Title: Formation of mask pattern
Inventor: KIRITA KEI
IPC: G03F1/00
Filed: 1986-04-30
Abstract: PURPOSE:To enable the formation of a high-accuracy mask by forming a thin film layer on a light shielding layer on a mask base material, then forming a prescribed resist pattern thereto, removing the thin film layer by dry etching and removing the light shielding layer by dry etching with the thin film layer pattern as a mask. CONSTITUTION:A resist film is formed on a mask substrate formed by successively laminating a molybdenum silicide film 12 and a chromium film 13 on the mask base material 11 and thereafter, the resist pattern 14 is formed. The thin chromium film 13 is selectively removed with said pattern as a mask. The molybdenum silicide film 12 is selectively removed by dry etching with the resist pattern 14 and the thin chromium film 13 as a mask. The difference in the pattern exchange between the resist pattern and the pattern of the light shielding layer is thereby decreased, by which the pattern of the light shielding layer 12 having good dimensional accuracy and sectional profile is formed.

Title: Semiconductor light emitting device
Inventor: HORI KENICHI
IPC: H01S5/12
Filed: 1980-07-23
Abstract: PURPOSE:To largely increase the width of a stripe obtaining basic lateral mode single oscillation by arranging the periodic structure of specific pitch at the part except the central region of the boundary of a buffer layer and a clad layer. CONSTITUTION:A part of an N type buffer layer 2, an N type clad layer 3, a nondoped active layer 4, a P type clad layer 5, and a P type contact layer 6 are sequentially laminated on the layer 2 on an N type substrate 1 to form a mesa stripe 7. A periodic structure 14, for example, sawtooth shape having a pitch of integer times of the 1/2 wavelength of the oscillation wavelength of a laser light is formed at an interval W1 at the central region along the longitudinal direction of the mesa stripe at the boundary between the layers 2 and 3. Thus, the light oozed from the layer 4 to the layers 3, 5 is partly scattered by the periodic structure, and is partly reflected into the layer 4. The scattered light has an effect to lower the reflectivity of the light directing toward the layer 4 from the striped side wall, and thus the width of the stripe capable of obtaining the basic lateral mode single oscillation can be largely increased.

Title: Cursor controller
Inventor: NISHIKAWA SHINJI
IPC: G06F3/038
Filed: 1988-04-22
Abstract: PURPOSE:To control the cursor position with no intervention of a CPU by counting the pulses showing the moving direction and distance of the cursor for production of the movement information and holding this information so as to realize the updating in each prescribed cycle for transmission of a control signal. CONSTITUTION:The shift pulse signals X(+), X(-), Y(+) and Y(-) are outputted in response to the movements of a pointing device 100. The signal X(+) shows the distance moved to the plus side on an X coordinate axis. These shift pulse signals are inputted to a shift data production circuit 101. The circuit 101 counts the supplied shift pulse signals to produce the shift information X(T) and Y(T) showing the moving direction and distance of the device 100 in terms of the X and Y coordinates and outputs both shift information to the X and Y data holding circuits 102 and 103 respectively. The circuits 102 and 103 hold these received information and update periodically these information via the clock signals received separately to apply the new information to a display device through the display screen as the cursor control signals X(C) and Y(C) respectively. Thus the load of a CPU is reduced together with improvement of the working efficiency because the cursor control is carried out independently of the CPU.
