Title: Voice coder
Inventor: REE MIRUTON DORUBI
IPC: G11B20/02
Filed: 1989-02-14
Abstract: PURPOSE: To enable a motion picture producer to offer his product encoded in a type-A noise reducing system in the form of a 'single stock in hand' by making the motion picture to be accepted by most listeners when the picture is reproduced at a movie house provided with an 'academic' monophonic format by arranging an encoder of the type-A noise reducing system modified so that its dynamic effect can become about 2/3 of the maximum compression and a spectrum sound recording encoder in series. CONSTITUTION: Voice input signals are coupled with a hybrid encoder 10 and the output of the encoder 10 is coupled with a transmission channel or sound recording channel. The encoder 10 is connected to a first encoder 12 having a first characteristic effect and a second encoder 14 having a second characteristic effect. The first and second encoders 12 and 14 are constituted in such a way that the voice input signals are first coupled with the input of the first encoder 12 and the output of the encoder 12 is coupled with the input of the second encoder 14. While the characteristic effect of the hybrid encoding is obtained by mixing or synthesizing the first and second characteristic effects together, these two phases are combined with each other.

Title: Variable inductance coil
Inventor: MATSUDA TETSUYA
IPC: H01F21/08
Filed: 1988-02-15
Abstract: PURPOSE:To make it possible to easily change inductance by utilizing the normal conducting-superconducting transfer of the high temperature superconducting material provided in a coil. CONSTITUTION:When the temperature of a high-temperature super-conducting material 2 is raised by a temperature control means 3, the high-temperature superconducting material 2 is changed to a normal-temperature superconducting material, its susceptibility becomes zero, and the permeability mus and the inductance are brought in the state wherein a ferromagnetic material is saturated. On the other hand, when the temperature control means 3 is turned OFF, the high-temperature superconducting material 2 is cooled down by the liquid nitrogen 5 located around it, and it returns to the superconducting state. At this time, susceptibility is -1, permeability mus becomes zero, and inductance becomes zero. As above-mentioned, the value of inductance can be altered by changing the temperature only. As a result, the inductance can be changed easily without requiring a mechanical movement and a bias current.

Title: Noise suppressor for nonexciting operation type electromagnetic brake
Inventor: ISHIKAWA KOJI
IPC: F16D65/18
Filed: 1991-02-28
Abstract: PURPOSE:To effectively reduce collision sound at the time of operating by burying an elastic body equipped with a projecting part projecting from the end surface in recessed parts partially provided in one end surface where a fixed iron core and a movable iron core are opposed to each other. CONSTITUTION:Recessed parts 12 such as ring channels and the like are provided in the inner and outer peripheries of the electromagnetic coil 2 of a fixed iron core 1, and elastic bodies 11 such as O-rings and the like are buried. Since the depth of each recessed part 12 is a little shallower than the thickness of the elastic body 11, the projecting part of the elastic body 11 is projected from the end surface of the fixed iron core 1. As the projecting parts of the elastic bodies 11 are partial by this construction, projecting dimension is contracted by pushing pressure of a movable iron core 4. Therefore, the movable iron core 4 is electrically, stuck more closely to the fixed iron core 1 to suppress increase of magnetic resistance, completely stuck to the same on account of design, and completely exhibits magnetic force. Moreover mechanically, contraction of the projecting part requires a collision time for distortion by that quantity, collision is slowly damped, and collision sound is reduced.
