Title: Pattern correcting device
Inventor: KURODA KATSUHIRO
IPC: G03F1/74
Filed: 1983-03-16
Abstract: PURPOSE:To enable the minute correction of patterns by simple processes by providing the means for observing a position for irradiation with ion beam on the sample surface by electron beam, thereby controlling the ion beam narrowed finely with high accuracy in positioning. CONSTITUTION:A standard mark is moved to the adjacency of the position 5 of ion irradiation at first in order to determine the position for irradiation with ion beam on the sample surface or the deflection sensitivity accurately. On that place, the ion beam is projected for desired time to form a metallic film. At this time, two kinds of operation are performed, without operating a deflector 6 and with operating it. After that, those formed metallic films are moved to adjacency of the position for electron beam irradiation 15. At this time, a length measuring device 25 measures quantity of the movement accurately. Under this condition, the measurement of the values of coordinates of the formed metallic films by the electron beam means the measurement of the coordinates system of the ion beam with using the coordinates system of the electron beam as a reference. Next, a cut-out part of the pattern is moved to the adjacency of the electron beam irradiation position 15 based on the data of MT22 and the position of the cut-out part of the pattern in view of the coordinates system of the electron beam is measured accurately. The measured coordinates value is converted into the coordinates value of the ion beam.

Title: Optical recording and reproducing device
Inventor: SOGO KOJI
IPC: G11B20/10
Filed: 1989-02-22
Abstract: PURPOSE:To precisely read data by deciding the central position of a pit at the central position between the rise and the fall of the output of a light receiving element even when the peak value of the output of the light receiving element is changed and using a pit detection signal which is generated according to the central position. CONSTITUTION:Light reflected on the track of a recording medium is received by the light receiving element and the rise and the fall of the outputs PDS1 and PDS2 of the light receiving element are detected by a comparator. Then, even when the peak values of the outputs PDS1 and PDS2 are changed between the rise and the fall, the central position thereof is fixed regardless of that change. Therefore, when the pit detection signal is generated based on the outputs MVS1 and MVS2 of a one shot multivibrator corresponding to the central position between the rise and the fall of the outputs PDS1 and PDS2, it is made one precisely corresponding to the pit interval T between the pits P1 and P2. Thus, in the case of using the pit detection signal, the data is precisely reproduced.

Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To prevent a finger gripping a film unit with a lens from entering the viewing angle of a photographing lens and to obtain excellent gripping feeling when the film unit with a lens is held for a photographing action. SOLUTION: A grip side surface 7 gripped by a right hand is provided with a snap ring 18. Then, an accessary ball 8 is coupled to the ring 18 through a coupling ring 20 so as to be freely displaced. When the grip side surface 7 is gripped by the right hand so as to be enveloped by utilizing a grip part 16 projecting to a front surface, the ball 8 is interposed between a palm and the grip side surface 7 and a space is kept between them. Thus, since the right hand is restricted to grip not so deep, the finger does not enter the viewing angle of the photographing lens 13. Besides, since the ball 8 freely swings on the grip side surface 7 when the film unit with a lens is carried, an accessary effect is achieved.

Abstract: PURPOSE:To easily manufacture a semiconductor laser of this design excellent in reproducibility by a method wherein an end face quantum well region formed of a quantum well whose well layer and forbidden bandwidth are narrower and larger than those of a quantum well layer respectively is provided to the quantum well layer obliquely intersecting it. CONSTITUTION:In a semiconductor laser of this design, a quantum well layer 14 and an end face quantum well region 15 are formed at the same time, and as a growth speed varies depending on the angle of a face in an MBE method, the well width and the forbidden bandwidth of the quantum well layer 14 are 80Angstrom  and 1.47eV respectively, and those of the end face quantum well region 15 are 56Angstrom  and 1.49eV respectively. Therefore, emitted light from the quantum well layer 14 is radiated outside from a reflection end face 19 without being absorbed with the end face quantum well region 15. As light is not absorbed with the reflection end face 19, the semiconductor laser operates stably up to an output of 100mW. As the layer 14 and the region 15 are simultaneously formed through a single crystal growth, the semiconductor laser of this design can be easily formed excellent in reproducibility and large in output.
