Title: Embedding injection mold
Inventor: ARIMA KOJI
IPC: B29K105/20
Filed: 1988-03-29
Abstract: PURPOSE:To certainly fix an embedding member and to prevent the concn. of an electric field, by forming the fixing surface opposed to the embedding member of a press pin into a curved surface. CONSTITUTION:The fixing surface 41 opposed to an embedding member 2 of a press pin 40 is formed into a curved surface. When this embedding injection mold 1 is used, the embedding member 2 can be certainly fixed not only in an up-and-down direction but also in a left-and-right direction by the fixing surface 41 formed into the curved surface. At the same time, the positioning of the embedding member becomes accurate and the unnecessary movement of the embedding member 2 is eliminated even when an injection grade resin is injected and an embedding injection molded product having uniform quality can be obtained. The curvature of the fixing surface 41 is pref. made same to or smaller than that of the cross section of the embedding member. Further, even when the embedding injection molded product is used in voltage machinery, the concn. of an electric field is relaxed and the embedding injection molded product excellent in dielectric breakdown characteristics can be obtained.

Title: S internal circuit for isdn terminal equipment
Inventor: HIRAIDE SATOSHI
IPC: H04L12/40
Filed: 1989-03-24
Abstract: PURPOSE:To prevent the deterioration of the impedance when viewed from the side of an S interface bus even though the power supplies of other ISDN terminal equipments are switched off by actuating a relay contact driving coil with the power supply output voltage of a certain ISDN terminal equipment and performing the connection and the disconnection to the S interface bus via a relay contact. CONSTITUTION:When the power supply of an ISDN terminal equipment is switched off, no current flows to the relay contact driving coils L1 and L2 of relay circuits 1 and 2. Then the contacts of both circuits 1 and 2 are turned off and these circuits are separated from an S interface bus. While the ISDN terminal equipment is kept switched on, the DC voltage is supplied from a power circuit 7 and the current flows to the coils L1 and L2. Thus the relay contacts l11, l12, l21 and l22 are turned on and the circuits 1 and 2 are connected to the S interface bus. Then these circuits are actuated under the control of an S interface control circuit 9. As s result, the impedance is never deteriorated when viewed from the side of the S interface bus even though the power supplies of other ISDN terminal equipments are turned off.

Abstract: PURPOSE:To reproduce an information signal satisfactorily, by reproducing the information signal of a voice signal on which an azimuth is attached and is recorded, etc., with a gapless thin film head of magnetic flux response type. CONSTITUTION:When the recording and the reproduction of a video signal and a voice signal are performed with a composite magnetic head 200, the head 200 is arranged so that the width direction of the gap parts 211 and 212 of a thin film head 210 can be set along the diameter direction of a floppy disk 20. At the time of recording, the video signal is recorded on tracks T1 and T2 with the head 210, and the voice signal is recorded on a track T3 with the thin film head 220. Meanwhile, at the time of reproduction, the video signal is reproduced from the tracks T1 and T2 with the head 210, and the voice signal is reproduced from the track T3 with an MR head 230. Therefore, the voice signal is recorded with the head 220 that is a ring type magnetic head, however, the reproduction is performed with the head 230. Since the thickness of the head 230 is thin, gap loss is scarcely generated, thereby, it is possible to heighten a C/N.
