Title: High-voltage transformer
Inventor: YUKIMURA YOSHIHIKO
IPC: H01F27/32
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To prevent a voltage drop of a high-voltage transformer due to creeping discharge. SOLUTION: With an insulating ring 70 provided on the inner peripheral surface of the peripheral sidewall of a core case body, an insulating void 72 is formed between the peripheral edges of the flange pieces 41 of a coil bobbing 40 and the ring 70. Accordingly, the void 72 and the ring 70 are ensured between the periphery of the bobbin 40 and the peripheral sidewall of the core case body. Therefore, the flange pieces 41 of the bobbin 40 do never come into contact with the inner surface of the peripheral sidewall of the core case body. Accordingly, the creeping distance of the bobbin 40 becomes a length to extend to the contact of the bobbin 40 with the front wall of the core case body, and the creeping distance is extended. As a result, a voltage drop of a high-voltage transformer due to creeping discharge can be prevented.

Title: Ink erasing liquid pen
Inventor: KAWABATA AKIRA
IPC: B43L19/00
Filed: 1987-07-15
Abstract: PURPOSE: To provide a low cost, high-density and high-viscosity correction liquid pen by a method wherein the sponge material in which a white correction liquid is impregnated is housed in a pen container made of a compressible and deformable material, while it is possible to prevent the liquid in the pen container from flowing out by bringing a cap-fitted coating unit into contact with the sponge material to receive supply of the white correction liquid. CONSTITUTION: A sponge material 2 in which the correction liquid is impregnated is crammed in a container 1. A coat functioning section 5 is fixed on a cap 3 by a supporter 4 so that the top of the coat functioning section 5 may reach the sponge material 2. The container 1 is made of an elastic material as hard as to be crushed by fingers. The removal of the cap facilitates the natural movement of the moderate volume of the correction liquid contained in the sponge material 2 to the coat functioning section 5. Since the container is made of a soft material, it is possible to not only agitate the liquid by repeatedly compressing the sponge from the exterior of the elastic container but also squeeze the liquid from the bottom of the container even, in the case where the amount of the liquid at the contact part with the coat function section 5 becomes lean owing to the long term use.
