Title: Position data thin-out device
Inventor: MIZUNO MASARU
IPC: G01C21/00
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To reduce a recording capacity by leaving effective position data only in a position calculation terminal, such as a navigation system. SOLUTION: In a position calculation terminal, the position of a mobile unit is calculated by a position calculation means 1 using an absolute position detection sensor such as GPS, a distance sensor such as vehicle speed pulse, and an angular speed sensor such as vibrating gyro. At the same time, positional accuracy is calculated by a position accuracy calculation means 2. When a positional error is determined to be less than a threshold by a position record determination means 3, a position recording means 4 records the position in a memory. By reducing the amount of data with leaving only effective position data in the memory, the position data recording capacity necessary for display of a traveling route can be reduced.

Title: Optical semiconductor module
Inventor: FUKUDA KAZUYUKI
IPC: H01S5/00
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To provide a semi-conductor module capable of stably performing silicon substrate junction in a resin mold package and stably operating a semi- conductor element and excellent in reliability by specifying the ratio of the width of a substrate member in the direction perpendicular to the light transmitting direction of an optical fiber to be mounted on the substrate member, to the width of a package having a lead terminal in the same direction. SOLUTION: The ration of the width of a substrate member in the direction perpendicular to the light transmitting direction of a optical fiber 13 to be mounted on a substrate member 3 to the width of a package 4 having a lead terminal 5 in the same direction is set to be 0.24-0.42. The heat in a semiconductor element can be efficiently radiated to the lead terminal of the package through the substrate member. When the ratio is increased and the junction area is increased, a peeling is generated between the substrate member and the package, and the heat transfer efficiency between the substrate member and the package is worsened. When the ratio is reduced, the joining area is reduced, the heat transmission becomes small, and the heat transfer efficiency is also worsened.

Abstract: PURPOSE: To enhance positional control of a printing pattern on a completed bag by measuring an actual distance between adjacent eyemarks and calculating an average actual spacing between the eyemarks to set a predetermined draw length so as to allow the same to substantially coincide with the spacing. CONSTITUTION: A plurality of eyemarks 32 are printed on a web 12 at an equal interval along the outer edge of the web 12 in order to accurately arrange a seal to the printing pattern 17 on the web 12 and the passage of the eyemarks 32 is detected photoelectrically by an optical scanner 34. The actual spacing between the continuous eyemarks 32 is detected and a predeterined nominal take-up length is set so as to substantially coincide with the actual spacing. Herein, a distance DL is set so as to almost coincide with a value obtained by adding one half the width of a 'detection window' to a value which is obtained by adding an error actually measured as a time of previous drawing to the nominal spacing of the eyemarks 32 capable of being set on a control panel 22 by a worker. By this constitution, the positional control of the printing pattern 17 on a completed bag can be enhanced.
