Title: Position detector
Inventor: OIKAWA KATSUYA
IPC: G01B11/00
Filed: 1989-09-27
Abstract: PURPOSE:To enable execution of position detection which is highly precise and of which the detection range is wide, by a method wherein the shape of slit edges controlling the width of a slit is so specified as to correspond to a light flux density distribution in a light-sensing means toward the direction of arrangement of a plurality of light-sensing elements. CONSTITUTION:A light flux emitted from a light source 2 is directed to a light-sensing means 4 in a range limited by a slit 3. While a spot having a shape corresponding substantially to the slit 3 is formed on a light-sensing surface in the light-sensing means 4, the spot is divided in two, in this case, by a secant line intersecting the direction 1-A perpendicularly and passing through the center of the light-sensing means 4, and the quantity of sensed light is detected by light-sensing elements 6 and 7 arranged on the left and the right of the scant line. Herein a position of detection and the distribution of a light quantity density are as shown in (c) in the case when the width of the slit 3, i.e. a distance between the side edges of the slit 3 in the direction intersecting the direction 1-A perpendicularly, is equal entirely. When the shape of the slit 3 is specified as shown in (b) so that the side edges of the slit 3 draw circular arcs projecting inside so that the distance between the side edges becomes smaller at a position which is nearer to the center of the spot, on the other side, the width of a flat area is expanded as indicated by dotted lines in (c).

Title: Production of purified yolk lecithin
Inventor: MIYATA KAZUNARI
IPC: C07F9/10
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain highly safe purified yolk lecithin by an economical means without using acetone. SOLUTION: A method for producing the subject purified yolk lecithin comprises a combination of the following two operations (1) and (2): (1) in a condition where lecithin forms a micelle, the micelle is subjected to filtration treatment through an ultrafiltration membrane 1 to recover the lecithin micelle a membrane-impermeable concentrate and (2) in a condition where lecithin forms no micelle, the micelle is subjected to filtration treatment through an ultrafiltration membrane 2 to recover the lecithin as a membrane-permeated liquid; wherein the condition where lecithin forms a micelle lies in hexane, whereas the condition where lecithin forms no micelle lies in a mixed solvent of hexane and an alcohol.  The purified yolk lecithin thus obtained has the following advantages: there is no acetone residue because of no use of acetone, and there is no fear of any offensive odor due to acetone condensates at all; furthermore, the purification means is only use of ultrafiltration membranes, therefore both equipment cost and maintenance cost are low.

Title: Semiconductor device and its manufacture
Inventor: AGAWA KENICHI
IPC: H01L27/088
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To form a sufficiently high resistance with less area and without increase the manufacturing processes by forming a resistor at the same time as when an LDD area of MOS transistor is formed, and using a diffusion area of a high resistance value wherein a mask is formed on its surface at the same when a side wall is formed as a resistor. SOLUTION: In this device, a diffusion area 23 of low concentration and shallow junction depth is formed in succession to a diffusion area 41. The diffusion area 23 is formed at the same time when an LDD area of a transistor is formed, and in the process thereafter, an insulating film 32 prevents formation of a silicide layer on the surface or additional ion implantation, thus a high resistance value is kept. With the diffusion area 23 used as a parasitic resistance of a transistor, a high resistance is formed with less area. The formation of diffusion area 23 makes the insulating film 32 remain in a specified area, so a single process of PEP for forming a resist mask 25 is only added. Thus, with less area, the increase in the manufacturing processes is made small.

Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a semiconductor device by preventing the island of a lead frame from being warped and to provide a lead frame and a semiconductor device which can prevent drop in quality and short- circuiting caused by break of a suspension lead. SOLUTION: A lead frame includes an island 11 for mounting a semiconductor chip, a plurality of leads 12 connected electrically to a semiconductor chip mounted on the island 11, and a frame 13 connecting the leads 12. The island 11 is independent of the frame 13 and is supported by a resin tape 16, in a state where it is connected to the frame 13. A semiconductor device is fabricated by cutting the resin tape 16 after the semiconductor chip is mounted on the island 11. Even if changes in the temperature caused accompanying resin forming is applied to the island 11 and the resin tape 16, since the thermal expansion/ contraction coefficient of the resin tape 16 is close to that of sealing resin as compared with a metal, stresses generated between the resin tape 16 and the sealing resin can be kept extremely small, thereby preventing the island 11 from being warped.
