Patent JP-S55113312-A (JP)
Title: Ignition coil
Inventor: HOSOKAWA NOBORU
IPC: H01F38/12
Filed: 1979-02-22
Abstract: PURPOSE:To stabilize the performance of an ignition coil at a low temperature by employing insulating gas together with insulating oil as insulating medium. CONSTITUTION:Insulating oil is filled in a container providing that small space is left. Then, the remaining space is filled up with an electrical negative gas having high dielectric strength such as SF6 gas and the container is sealed. The SF6 has high dielectric strength and is very stable chemically. No chemical change is made even after existing with insulating oil and dielectric strength remains unchanged. Even if insulating oil solidifies and the volume is reduced at a low temperature, only the gas pressure of SF6 drops and dielectric breakdown will not cause due to no occurrence of vacuum bubble. Therefore, it will be used steadily up to around the boiling point of SF6 (about -60 deg.C). In addition to SF6, flon gas, or flon gas and air mixture will be used. Insulating gas absorbs a rise in pressure in the container due to the heat of coil and there is no danger of blast.

Title: Transfer molding method
Inventor: HIRATA KOICHI
IPC: B29C45/14
Filed: 1985-02-06
Abstract: PURPOSE:To obtain stabilized casting terms, by casting heated thermoplastic resin to a cavity part of a molded material through two or more casting ports. CONSTITUTION:Resin casting ports 31 are provided at two corner parts 2 of a package. As for a width W' of the resin casting port 31, a half of the size W which is required as a conventional case is enough for the same. As for the width of the resin casting port, it is not always necessary to make the same into the width W', and it is good if the sum total of widths of a plurality of the resin casting ports in three or more positions is either identical with the size W or larger than that. In case a limited space in the cavity is imagined, as a quantity of resin passing through the space becomes small as compared with that of a conventional method, it becomes possible to control a deformation quantity to be given to an article existing in the interior low and molded material which is miniaturized and high-quality can be manufactured.

Abstract: PURPOSE:To form a thin film of single crystal in good reproducibility, by partially removing an oxidized film formed on the top of a polycrystal film, melting and recrystallizing the polycrystal film so that explosion of the polycrystal film and the oxidized film occurring in melting can be prevented. CONSTITUTION:For example, a Si substrate 1 is thermally oxidized to form a SiO2 film 2 on the top and further a SiH4 gas is thermally decomposed by the use of vacuum CVD device to pile a Si film 4 on the SiO2 film. Then, SiH2Cl2 is reacted with a NH3 gas by the use of the vacuum CVD device, a nitride film 6 is piled and pattern formation of the nitride film 6 is carried out by plasma etching. Then, LOCOS growth is carried out in high-temperature steam to form a LOCOS oxidized film 3 of poly Si and the nitride film 6 is removed with hot concentrated phosphoric acid. Then, the resulting film is thermally oxidized in a high-temperature dried oxygen to form a SiO2 film 5 and the SiO2 film 5 is partially removed. Then, the film is irradiated with CW argon ion laser. Explosion of the polycrystal film 4 and the oxidized film 5 caused by volume expansion resulting from melting of the polycrystal film 4 by the laser beam irradiation can be suppressed by partial removal of the oxidized film 4 and the thin film of single crystal can be formed in good reproducibility.
