Title: Printed wiring board
Inventor: NAGURA KEIJI
IPC: H05K3/34
Filed: 1987-07-13
Abstract: PURPOSE:To eliminate a troublesome work of applying and removing a masking tape to and from a land area for components to be attached later by a method wherein a 2nd resist layer which is not melted at the temperature of a solder bath but is melted at the temperature of a solder iron is formed on a land resist layer on a board. CONSTITUTION:A conventional land resist layer 3 is formed on a conductor layer 2 formed on a board 1 as a 1st insulating layer. A resist layer 4 which has a melting point lower than that of the resist layer 3 is formed on the resist layer 3 as a 2nd insulating layer. The resist layer 4, i.e. the 2nd insulating layer, is made of material which is not melted at the processing temperature of a solder bath but is melted at the temperature of a solder iron. As a land area (a) for components to be attached later on the board 1 is protected by the resist layer 4, even if the board 1 is subjected to a solder dip treatment in the solder bath, the solder does not adhere to the lands of the components to be attached later. With this constitution, the construction of applying a masking tape can be eliminated and the adhesion of solder at the time of the solder dip treatment can be securely avoided by a very simple means.

Filed: 1981-10-30
Abstract: PURPOSE:To obtain an iron core having a sufficiently low residual magnetic flux without providing any gap, by a method wherein an annular iron core is manufactured from an amorphous magnetic material and employed as an iron core without subjecting the same to annealing. CONSTITUTION:An amorphous magnetic material is formed into an annular iron core used for a current transformer. If such a core is not subjected to annealing, the iron loss thereof is small but the magnetizing force thereof is large compared with a directional silicon steel strip for the same flux density, and the residual magnetic flux density of the core shows a sufficiently low value as shown in the figure. Accordingly, if an annular iron core is manufactured from an amorphous magnetic material and employed as an iron core without subjecting the same to annealing, then an iron core having a sufficiently low residual magnetic flux is obtained without providing any gap.

Title: Data transmission method near high voltage charge section and abnormal access alarm system to high voltage charge section
Inventor: MANO YOSHIMOTO
IPC: H02G1/02
Filed: 1992-06-11
Abstract: PURPOSE:To prevent occurrence of noise or error even when data are sent in a radio wave near a high voltage charge section by sending a data signal synchronously with a specific time for increasing and decreasing band of a voltage of the charge section. CONSTITUTION:A voltage induced in a conductor directed toward a charge section direction or a counter charge section direction is detected to check a change in a voltage of a charge section and a data signal is sent in a radio wave synchronously with a period between 1/8-3/8 cycle of a maximum amplitude point of time or between 5/8-7/8 cycle after an increasing and decreasing zone of the voltage of the charge section. That is, since production of corona noise is small for the cycle period in the correlation between the corona noise occurrence time and the amplitude of the voltage of the high voltage charge section, a data error is reduced by sending the data synchronously with the cycle time.
