Title: Investigating method for moisture permeable path
Inventor: SAKAI KUNIHITO
IPC: G01M3/20
Filed: 1981-03-12
Abstract: PURPOSE:To make a moisture permeation speed and a moisture permeable path clear with regard to resin-sealed products, by checking the moisture permeable path by mixing a material which changes color owing to moisture absorption, with at least a part of resin. CONSTITUTION:A sample sealed with white resin 8 which never mixes with cobalt is cut, and the color changes of cobalt-mixed resin layers 7 with which the tips of leads 3 and a die pat 5 are coated is checked visually. On the basis of a difference in color of a lead indication part 9 between the cutting and decomposition of a sample sealed with resin 6 with which cobalt is mixed, the condition of moisture permeation from gaps in the interface between the resin layer 7 and the leads 3 is visually checked. When a frame 1 coated with the cobalt-mixed resin 6 is cut, the formation of gaps in the interface of the leads 3 is checked visually by the color change of the resin layer 7.

Title: Capacitance type acceleration sensor and detecting method
Inventor: HIGUCHI MASAYOSHI
IPC: H01L29/84
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized highly sensitive capacitance type acceleration sensor having a wide electrode area. SOLUTION: Both sides of the supporting plate 12 of a semiconductor substrate 10 are supported by a frame body 13 and the plate 12 is bent and deformed in an arch-like state when the plate 12 receives an acceleration. The central part of a movable plate 16 maintaining a planar shape is locally connected to and supported by the central part of the supporting plate 12 through a column section 14 and the plate 16 makes parallel displacement in the thickness direction when the supporting plate 12 is bent, but the planar shape of the plate 16 is maintained.  Therefore, when second and first electrodes 21 and 22 are respectively formed on the movable plate 16 and the supporting plate 12, etc., faced oppositely to the plate 16, the distance between the electrodes 20 and 21 and, accordingly, the capacitance generated between the electrodes 20 and 21 change as the supporting plate 12 is deformed. Since the movable plate 16 is put on the supporting plate 12, the conventional dead space occupied by a beam, etc., disappears and the occupation ratio of the electrode area in the planar shape of a sensor chip increases.

IPC: G02B6/122
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To make an element size smaller than heretofore and then to improve productivity and yield. SOLUTION: The sectional plane of a first waveguide 21 is set to about 8×8μm for transmitting light in a single mode. A taper part 22 succeeding to the first waveguide 21 shifts the light propagated through the first waveguide 21 to a multi-mode. A straight line part 23 succeeding to the wide width end part of the taper part 22 brings the wave front of the light shifted to the multi- mode from a spherical shape close to a planar shape. On the outgoing end side of the straight line part 13, a second waveguide 24 and a third waveguide 25 in a single mode are arranged so that the incident end surface is opposed to the outgoing end surface of the straight line part 23 through a minute gap. These waveguides 24, 25 are formed so as to be away from each other along a radius R of curvature of <=50mm, e.g. 20mm accordingly to be away from the incident end.  The width and the length of the straight line part 23 are set in the optimum value that a connection loss between the straight line part 23 and the second and the third waveguides 24, 25 becomes minimum, e.g. 15μm and 100μm.

IPC: C03B27/04
Filed: 1995-02-24
Abstract: PURPOSE: To prevent the occurrence of crack at the time of cooling by changing the cooling capacity during tempering, by which the generation of a thermal stress larger than needed in a temp. region where a surface layer does not induce viscous fluid any more, in a process for producing the tempered glass by physically tempering the glass heated near to its softening point. CONSTITUTION: A high temp. difference ΔT1max (TM1 -TS1 ) is generated between a surface temp. TS1 and a central temp. TM1 by supercooling of the glass surface as shown in Figs. (a) to (c), by which a tensile stress is generated in the glass surface and a compressive stress in the central part of the glass, and the crack is made liable to occur in the glass plate. On the other hand, the glass plate heated up to a temp. T0 near the softening point is subjected to tempering with a high cooling capacity in the same manner as heretofore in the process for production of the tempered glass as shown in Fig(a). The cooling capacity is made small when the glass attains the temp. region where the surface layer does not induce the viscous fluid any more. The cooling capacity is so adjusted that the temp. difference Τ2 between the surface temp. TS2 and central part temp.  TM2 shown in Fig. (b) attains an adequate temp. difference ΔT2max (= TM2 -TS2 ).

Title: Carmofur-containing liposome
Inventor: SUNAMOTO JIYUNZOU
IPC: A61K9/127
Filed: 1983-03-09
Abstract: PURPOSE:The titled preparation that is obtained by forming carmofur into liposome, thus being used as an anticancer agent with increased solubility and reduced side-effects. CONSTITUTION:The objective preparation is a liposome containing carmofur: 1- hexylcarbamoyl-5-fluorouracil. Carmofur has been widely used as an antitumor agent against pyrimidine metabolism-antagonizing malignant tumors and applied to gastric cancer, coli cancer and mammary cancer, however, it is very hardly soluble and relatively easily hydrolyzed under physiological conditions. The formation of liposome with carmofur increases the solubility of the compound in water more than 100 times, inhibits the hydrolysis even in 9.1pH, thus it can be prepared in an injection solution. The liposome is formed by the thin-film or solution-casting method and a phospholipid such as phosphatidylcholine is used as a medium.

Abstract: PURPOSE: The titled white fluorescent substance that is prepared by mixing a fluorescent substance prepared by doping a Pr-activated fluorescent substance R 2 O 2 S;Pr with a specific amount of Sn, with an electrically conductive material, thus having improved surface conductivity to low-speed electron rays and increased brightness.  
     CONSTITUTION: A Pr-activated blue fluorescent substance R 2 O 2 S;Pr (R is Y, La, Lu, Gd, Sc) is doped with Sn by 0.005W5atomic% based on R to give a fluorescent substance. The product, preferably Y 2 O 2 S;PrSn, is mixed with an electrically conductive material, preferably In 2 O 3 ,SnO 2 ;Sb to give the objective fluorescent substance.  
     EFFECT: Since Sn only improves the surface conductivity of R 2 O 2 S and does not relate to the emission characteristics of Pr, the relationship between the emission intensity and Pr activation, known in the excitation with high-speed electron rays, also is kept in the excitation with low-speed rays.
