Title: Mold and method for manufacturing spectacle glass mold
Inventor: FUSE HIROAKI
IPC: B29L11/00
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To enable the setting of a diameter of a glass mold within a limited tolerance without making the tolerance of glass preform strict by forming a rotationally symmetric run-off portion not being contacted with the glass preform and having the center of a press mold as its center on the press surface for pressing the glass preform of the press mold. SOLUTION: A run-off portion 22 not being contacted with a glass preform 30 is formed on the center of the press surface 21 of a press mold 22 with respect to the master mold 10. The run-off portion 22 is formed as being R>r when the radius of curvature of a convex spherical surface at the press surface 21 side of the glass preform 30 is set to R, and the radius of curvature of a concave spherical surface of the press surface 21 is set to (r). By the agency of difference between R and (r), the run-off portion 22 remains even in a state of the completion of the glass preform 30.  As a result, unevenness of molding factors such as an outer diameter or central thickness of the glass preform 30 and a quantity of molding can be absorbed by the change of a running off quantity of the glass preform to the run off portion, so that the dispersion of the outer diameter of a glass mold can be set within the narrow range.

Filed: 1992-04-15
Abstract: PURPOSE:To increase the yield of the wafer by a method wherein the surface roughness of the surface of the wafer part is set at 0.07mum or less in Ra value (center line average height). CONSTITUTION:An etchant is supplied to a stacked body of a plurality of silicon wafers; the surface of its chamfered part is brought into contact with the etchant. The time of this contact is set normally at about 30 to 120 seconds. For example, an etchant within a range of HF:HNO3=1:2 to 5 is used as the etchant. As a result, the chamfered part of the silicon wafers is etched sufficiently, and the surface roughness of its etched face is set to 0.07mum or lower in an Ra value (central-line mean value). Thereby, it is possible to reduce that a slip is caused due to the thermal stress of semiconductor wafers.

Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To perform double protection so that a user who is not registered on a main system can not access to the system by authenticating a user based on the password of a user and a timing vector. SOLUTION: When a user input a log-in name and a password, a password matching part 110 checks whether or not the password coincides with a registered password and a pattern fetching part 120 fetches a timing vector from its key stroke characteristic. A comparing part 140 receives the timing vector of the user and compares difference between input and output of a neural network 130 with threshold TH. When the difference is larger than the threshold TH, a 2nd designation signal S2 of a level 7 is outputted to an access controlling part 150, and when the difference is not, the signal S2 of a level 8 is outputted to the part 150 respectively. The part 150 inhibits or permits accessing the system in response to the signals S2 of the level 7 or the level 8.

Title: High-frequency lighting device with light-adjusting function
Inventor: UEHARA SHIGEKATSU
IPC: H05B41/39
Filed: 1989-05-16
Abstract: PURPOSE:To prevent the occurrence of parallel resonance so as to reduce the noise of an electric discharge lamp by connecting an electrode on the non-reactor presence side of the electric discharge lamp to a site not charged with a high-frequency potential directly or via a capacitor and at the same time avoiding the capacitor from being connected in parallel to a reactor. CONSTITUTION:An electric discharge lamp 7 is connected at one end of its electrode directly to the connection point (a) of power capacitors 2A and 2B and also connected at the other end to the united point of switching elements 9A and 9B via a reactor 8 and a reactor 4. When a change-over switch 12 in a circuit constructed in such a manner like this is opened, an electric discharge lamp 7 is high in impedance of the circuit thereof and the brightness thereof is therefore set in the light-adjusting condition. When the change-over switch 12 on the other hand is closed, only the reactor 8 becomes a current-limiting element so that the impedance of an electric discharge circuit can be lowered to set the brightness of the electric discharge lamp in its 100% lighting condition. Since any parallel resonance circuit against the L of the reactor 8 or 4 is not constructed in every above-mentioned lighting condition, no noise voltage is generated.
