Title: Resin mold key
Inventor: OMAE TERUYUKI
IPC: E05B19/04
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To make occurrence of a weld line on a pinch part which is molded from synthetic resin while members at least including the base member of a key plate are inserted, in order and to enhance the external appearance. SOLUTION: A holder (insert member) 17 receiving and holding therein a base part 14 of a key plate 11 and an electronic part 20 is formed in an asymmetric shape so as to be biased toward a synthetic resin filling position 21 with respect to the center part 12a of a pinch part 12. Accordingly, one of opposite sides which has a longer distance from the synthetic resin filling position 21 to the center part 12a of the pinch part 12 on the opposite side thereto, has a synthetic resin passage having a larger width W1, and accordingly, the synthetic resin can smoothly flow therethrough. The other one of the opposite sides which has a shorter distance (L2) therebetween has a synthetic resin passage having a small width W2, and accordingly, the synthetic resin can hardly flow therethrough.  With this arrangement, the filled synthetic resin merges in a part extending from the filling position 21 to the center part 12a of the pinch part 12 on the opposite side, thereby it is possible to occurrence of a weld line in order in the center part of the pinch part 12.

Title: Device and method for detecting focus and storage medium
Inventor: KIKKO MIKIO
IPC: G02B7/36
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a focus detector constituted so that focusing can be executed by a prescribed small number of measuring times without being affected by the position of an object. SOLUTION: This focus detector is constituted so that the vicinity of a position where the contrast of an image to be picked up becomes the maximum is decided as the focusing point position of an image pickup optical system. Then, the image pickup optical system is set at two initial positions (a) and (b) being different in an optical axis direction and contrast values C(a) and C(b) at two positions are respectively calculated. Then, the position (a) where the contrast value is low out of two positions is moved so as to approach the position where the contrast value is high. When a distance between two positions falls within a prescribed value (allowable focusing depth=S), these two positions are decided as the focusing point positions.  Even wen the focusing position approaches one out of two initial positions (a) and (b), the image pickup optical system can be moved to the focusing position by a small number of measuring times.

Title: Compensating window for angle of divergence of laser
Inventor: HAMADA NAOYA
IPC: H01S3/034
Filed: 1984-12-06
Abstract: PURPOSE:To obtain constant laser-condensing performance and further fixed processing performance by a simple beam transmission system without unnecessarily enlarging a mirror for transmission and a condenser lens by using an optical material having small thermal strain and previously processing a window to a convex lens shape so as to compensate an angle of divergence of a laser. CONSTITUTION:Doughnut mode laser beams extracted from an unstable type laser resonator are deflected by a total reflection plate mirror 3, and extracted outside an oscillator 1 through a laser-beam extracting window 5. Laser beams are refracted by the window 5 previously processed to a convex lens shape, and oscillator-output beams are made approximately parallel. KCl, etc. are used as the principal ingredients as the quality of materials of the window 5, and the form and refractive index of the window hardly change even to large-output beam transmission for a prolonged time, and the focal distance of the window is set in such a manner that beams are extracted by a parallel plate window having the same quality of materials, the angle of divergence of beams is measured and a value compensating the angle is calculated. Accordingly, approximately parallel beams can be taken out of the laser oscillator, thus simplifying a transmission system, then stabilizing processing.

Title: Optical switch
Inventor: HAMADA TOMOYUKI
IPC: G02F1/313
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To impart a memory characteristic to an optical switch and to occasionally change its memory state. SOLUTION: At least one ferroelectric thin films 2 are formed on a substrate 1 having an electro-optic effect and the spontaneous polarization electric field of the ferroelectric thin films 2 acts on the substrate 1 to change the refractive index of the substrate 1 by the electro-optic effect. The spontaneous polarization electric field of the ferroelectric thin films 2 acts on the adjacent substrate and the refractive index of the substrate is changed by the electro-optic effect. Since the spontaneous polarization of the ferroelectric thin films 2 remains, the refractive index change persists and the optical switch having the memory characteristic may be obtained.

Molten fluids for crystal growth are thereby prepared and cooled at a constant descending rate of temperature. Simultaneously the substrate holder 5 is slidden to successively contact the substrate 6 with each of molten fluid in the reservoirs 21a-21d and to form multilayers of epitaxial growth on the surface of the substrate 6.
