Title: Device for manufacturing photomagnetic disk
Inventor: NIIHARA TOSHIO
IPC: H01F10/12
Filed: 1984-04-06
Abstract: PURPOSE:To lay a magnetic thin film having a good characteristic on a dielectric film formed on a substrate without breaking the vacuum condition of a manufacturing device, by installing a conductive antenna which impresses a DC bias to the upper electrode for forming magnetic thin film. CONSTITUTION:A disk substrate 1 to be covered with a magnetic thin film is fitted to the upper electrode 7 by means of a substrate holder 6 and a conductive antenna 9 for impressing a DC bias voltage installed to the holder 6 is contacted with the substrate 1. It is constituted that the antenna 9 is contained in the holder by means of a prescribed wire when the upper electrode 7 is turned clockwise. At the time of forming the magnetic thin film, the upper electrode 7 is first turned clockwise and a dielectric film is formed on the substrate 1 by means of a target 15 without impressing the DC bias voltage. Then the upper electrode 7 is turned counterclockwise and the magnetic thin film is formed with another target 17 while the DC bias voltage is impressed. Therefore, the magnetic thin film having a good characteristic can be laid on the dielectric film without breaking the vacuum condition.

Title: Signal transmission system
Inventor: SATO TAIJI
IPC: H04M1/715
Filed: 1987-03-24
Abstract: PURPOSE:To ensure crosstalk attenuation even through an unbalanced signal transmission line by providing an inverting means inverting the phase of input/ output on the optional position of the signal transmission line. CONSTITUTION:Induction currents (b), (c) are generated in a channel 31 by a signal current (a) flowing to a speech path 30. Since a phase inverting transformer 40 is provided on the speech path 31, the induced currents (b), (c) are cancelled and the effect of the channel 30 in the channel 31 is reduced. Moreover, the direction of winding of the phase inverting transformer 40 is made opposite and the transformer 40 is provided at a position by which the induction current (b) is nearly equal to the current (c). Thus, the crosstalk attenuation is ensured even through the unbalanced type signal transmission line and small- sized and low cost device is attained.

IPC: H04R7/02
Filed: 1985-03-29
Abstract: PURPOSE:To provide water resistance, oil resistance and weatherability of the titled diaphragm by using a fluoroplastic film to coat the surface of a diaphragm base after the diaphragm base is immersed with a methyl methacrylate resin solution and dried. CONSTITUTION:After the diaphragm base paper-made to a prescribed shape by using natural fiber and/or chemical fiber as major materials is immersed with the methyl methacrylate resin solution and dried, the surface of the diaphragm base is coated by the fluoroplastic film. Since the surface of the diaphragm is coated strongly by the fluoroplastic film by the filler coating effect of the methacrylate resin immersing processing and fluoroplastic immersing processing, the invasion of water, oil or grease is prevented and the diaphragm which water and oil resistance where the Young's modulus and the internal loss incur so much change is obtained. Further, no deterioration in strength due to the invasion of the solvent is caused, the acoustic characteristic such as the frequency characteristic and the low frequency dubbing characteristic is unchanged even under a temperature of 150-200 deg.C in this solvent-resistance and heat-resistant diaphragm.

Title: Heating device
Inventor: UEDA SHIGEKI
IPC: H05B6/78
Filed: 1981-05-06
Abstract: PURPOSE:To improve the accuracy of weight detection by supporting a scale of food weight measuring type heating device vertically slidable by a leaf spring having a load sensor at scale shaft which pierces through rotating stand shaft, and by making the scale rotatable along with the rotation of the rotating stand. CONSTITUTION:A rotating stand 4, a driving shaft 7 and a rotating rack 8 are fixed in the direction of thrust. The shaft 15 of a scale 14 pierces through a driving shaft, freely slidable, and the tip of it is held by a leaf spring 16. When food is placed on the scale 14, the scale 14 dips regardless of the rotating stand 4 or others, pushing down the leaf spring 16, detecting the weight by the load sensor 11, and controls the electricity supply to a magnetron 2 via a controller 12. Weight measuring is done accurately free of effects of the rotating stand and others. When the rotating stand 4 is rotated by a driving source 5, a projection 18 of the rotating stand 4 engages with a projection 19, rotating the scale 14 and cooking starts. The accuracy in weight measuring is thus improved and the reliability is also improved.
