Title: Record disc regenerator
Inventor: KAWAMURA ICHIROU
IPC: G11B17/04
Filed: 1983-11-14
Abstract: PURPOSE:To securely protrude the interposing hold mechanism even for the extreme insertion operation by converting the force inserting a case with a lever having a supporting point, to hasten the operation of the finger interposing and holding the record, and composing so as to increase the energizing force in the insertion direction. CONSTITUTION:A board spring 202 is fixed to a lever 200, and when the board spring is pushed as an arrow mark V, a connecting end 200a of a lever 200 is composed to connect with 1 end of a pin 162 and to push a pin 162 in the arrow W direction. When the case is inserted, a board spring 202 is installed to the height in which the lower side beam of the expansion mechanism is connected. When the case is inserted, a board spring 20 is connected to the lower side beam, is pushed in the arrow V direction and the spring force is accumulated. Namely, a pin 162 is strongly pushed in the arrow W direction by a lever 200; and the speed of a finger 131 is increased by the force for pushing in the W direction. Thus, the operation of the finger can sufficiently respond and over take even for the extremely fast inserting operation.

Title: Method for controlling plating film in electroless copper plating
Inventor: TAKAHASHI TOMOAKI
IPC: C23C18/40
Filed: 1994-09-08
Abstract: PURPOSE: To obtain a printed board uniform in film thickness by electroless plating even if the plating rate varies from turn to turn and from batch to batch and to reduce the roughness on the surface of a plating film by adjusting the dissolved oxygen concn. in the plating soln. CONSTITUTION: In the method for electroless plating a printed board with copper, the dissolved oxygen concn. in a plating soln. is adjusted, and the copper plating reaction is stopped at the optional time to obtain a plating film having a desired thickness. Alternatively, the dissolved oxygen concn. in the soln. is adjusted, and the board is dipped in the soln. for a specified time and electroless- plated with copper. The plating films having about the same thickness are obtained in about the same time. As a result, the working time is shortened, the surface roughness of the obtained plating film is reduced to 1/3 to 1/12 of that in the conventional process, and a uniform plating film is obtained.

Title: Ion beam sputtering device and neutralizer
Inventor: ISHIKAWA YASUSHI
IPC: C23C14/46
Filed: 1989-08-21
Abstract: PURPOSE:To prevent the lowering of a sputtering rate by radiating electrons from an electron supplying source provided off the orbit of an ion beam and imparting the momentum directing toward a desired direction to the electrons by a directivity imparting means. CONSTITUTION:A target 6 is irradiated with the ion beam 5 radiated from an ion generator 1 and a film is formed on a substrate 8 by sputtering particles 7 released from the target 6. A filament 9a is heated at this time to radiate thermions 12 and the momentum is imparted to the electrons 12 by the electric field formed by applying a negative potential to a conductor 11a by a decelerating power source 10 to accelerate the electrons 12 toward the ion beam 5 and the target 6. The electrons 12 are, therefore, splashed, are taken into the ion beam 5 and neutralized without generating an electron sleeve around the filament 9a. The target 6 is simultaneously neutralized, by which the lowering of the sputtering rate is prevented and the film forming rate is improved.

Title: Method for establishing key while using aerial communication and password, and password protocol
Inventor: BERENZWEIG ADAM L
IPC: H04L9/08
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for establishing key while using aerial communication and password by allowing communication parties to mutually exchange the calculated results and each party to add the password to his own exponent when the calculated result is generates. SOLUTION: Mobile equipment 20 generates a random number RM and calculates (g'RM+p)mod p while using a prime number (p) and a generator (g) of a group generated by the prime number (p). Next, the mobile equipment 20 transmits the rime number (p) and generator (g) to a network 10 together with (g'RM+p)mode p. The (g'RM+p)mod p is equal with (g'RM+p)+(p mod p) and since the network 10 knows the password, (p mod p) is calculated so that (g'RM+p) is extracted from (g'RM+p)mod p. The network 10 generates a random number RN and next calculates (g'RM mod p)'RN but this is equal with (g'RMRN mod p). The network 10 selects the hash of this (g'RMRN mod p) as a section key.

Filed: 1990-08-15
Abstract: PURPOSE:To easily form the ring-shaped converted image by applying the small bottom surface of a reflecting umbrella in a truncated cone shape which has a mirror surface as its internal surface to an original picture and photographing it from the direction of the large bottom surface by a camera whose center axis is aligned with the truncated cone.
