Title: Optical system for semiconductor laser
Inventor: KAWAMURA NAOTO
IPC: G02B27/09
Filed: 1978-04-28
Abstract: PURPOSE: To maximize the peak intensity of the spot on recording face by collimating the exit light from a semiconductor laser with a paralleling optical system of a  differenct focal length in the orghogonal direction and entering the same to the pupil of an image forming lens thereby forming the beam in elliptical shape.  
     CONSTITUTION: Exit light from a semiconductor laser 1 is approximately collimated by a spherical lens 5c, and the beam diameter in the y (longitudinal axis) direction is magnified by a cylindrical beam expander 5d. The light out from the expander 5d passes through the image forming lens and forms its spot on the recording face 7. The luminous flux actually advancing to the recording face of this case is shown by solid lines and the luminous flux becoming 1/e 2  (beam) with respect to the central intensity of the luminous flux emitted from the laser light source by dotted lines, respectively. The focal length of the lens 5c is about 6 mm and the beam diameter r with respect to the radius R of the incident pupil 8 of the image forming lens satisfies the neighborhool of r/R≈0.892. Thereby, the peak intensity of the spot on the recording face may be maximized.

Title: Semiconductor device
Inventor: KONDO RYUJI
IPC: H01L27/14
Filed: 1989-03-06
Abstract: PURPOSE:To enhance the moisture resistance of a semiconductor device by a method wherein a light transmitting material larger than the plane size of a photoelectric transducer is brought into close contact with the light-receiving section of the photoelectric transducer, and the photoelectric transducer is positioned in the frame molded using thermal plastic resin. CONSTITUTION:A frame 5 serving as a part of a package is molded using thermal plastic synthetic resin. A glass 2 larger than the plane size of a photoelectric transducer 5 is closely contacted with the light-receiving surface of a photoelectric transducer 3 placed in the frame 5. The periphery of the glass 2, the photoelectric transducer 2 and the frame 5 are formed into one piece using thermal hardening resin injected by potting. Therefore, the interface distance from the surface of the glass plate 2, i.e., the surface in contact with outer air to the photoelectric transducer 3 becomes longer in correspondence with the size of the glass plate 2. The path of water infiltration becomes longer, and the contact with epoxy resin 4 in the interface becomes strong. As a result, moisture resistance is improved.

Title: 90× distributor
Inventor: TANAKA HIROAKI
IPC: H01P5/18
Filed: 1994-03-23
Abstract: PURPOSE:To make a device small in size and thin without increasing the insertion loss. CONSTITUTION:Two parallel micro strip coupled lines 12 and 13 having length lambdag/4 are formed on the upper face of a dielectric substrate 11 having a high dielectric constant (preferably 20 or more), and a ground electrode 140 is formed a prescribed gap apart from micro strip coupled lines 12 and 13. The characteristic impedance in a 90 deg. distributor 100 is determined by a line width W, a line space S, a gap G between the line and the ground electrode, and the specific dielectric constant of the dielectric substrate 11. Thikness (t) of the dielectric substrate 11 doesn't have a large influence upon the characteristic impedance. Therefore, it is unnecessary to extremely narrow the line width W because the gap G between the line and the ground electrode is properly selected to set the characteristic impedance to a prescribed value. As the result, the element is miniaturized without increasing the insertion loss. Since the thickness of the dielectric substrate 11 can be changed without an influence upon the characteristic, the element is made thin.

IPC: F02B31/02
Filed: 1995-03-13
Abstract: PURPOSE: To prevent spatial disadvantage and the deterioration of performance by restraining reduction in the swirl ratio by interference of flows of sucking air. CONSTITUTION: Intake air helical ports 11 and 12 to communicate with opening parts in which intake valves 4 and 5 are arranged, are formed in a cylinder head 2. Projections 13 and 14 are formed inside the ports 11 and 12 in a part where both ports 11 and 12 approach each other so as to project in the side part direction. Sucking air introduced into the intake air helical ports 11 and 12 flows while drawing a swirl downward along an inner wall, and is introduced into a cylinder 3, and forms a swirl as a whole. In a part where flows of sucking air approach each other, there is the possibility that the flows interfere with each other in the cylinder 3, but the sucking air is distributively flowed in the vertical direction as the projections 13 and 14 as a boundary in the ports 11 and 12. Therefore, the flows of the sucking air are weakened in a part where there is the possibility of interference, and a degree of interference can be reduced.
