Title: Digital non-linear pre-emphasis/de-emphasis apparatus
Inventor: OHTA HARUO
IPC: H04N5/923
Filed: 1987-11-11
Abstract: A digital non-linear pre-emphasis/de-emphasis apparatus is disclosed. A frequency band of a high-pass filter (100) for extracting a high frequency component signal of an input signal is varied according to the input signal by feeding back the output signal of the high-pass filter through a first non-linear input/output circuit (7). The first non-linear input/output circuit multiples the output signal of the high-pass filter by a coefficient which is a function of the output signal of the high-pass filter to obtain a feedback signal. The out­put signal of the high-pass filter is applied also to a second non-linear input/output circuit (9) which multiplies the output signal of the high-pass filter by a coefficient which is a function of the output signal of the high-pass filter. An output signal of the second non-linear input/output cir­cuit is mixed with the input signal by an operation circuit (12) to obtain an output signal which is non-linear emphasized or de-emphasized.

Abstract: A method of connecting a cordless telephone by radio without using control channels selects priority radio channels from radio channels which are shared by cordless telephones and assigns each of them to a respective one of the cordless telephones. So long as the priority radio channel assigned to any of the telephones is not occupied by another telephone, that telephone uses it. A portable unit of the telephone is allowed to enter into a call origination flow in response to a call origination request only after confirming that an incoming calling signal is not being sent over the priority radio channel from a fixed unit which is associated with the portable unit. Even when a call origination request occurs before a radio connection for an incoming call, the fixed and portable units are prevented from tuning to different radio channels without the need for a control channel.

Abstract: Such a chopper circuit is used for controlling electromagnetic and/or stepping motor coils (8; 26), particularly for a matrix printer, whose inductance, in conjunction with the applied voltage, generates a maximum current which is, however, adjusted to be reduced by a desired factor, it being possible to generate the current ripples (7a) by chopping. 
<??>These current ripples (7a) can now be varied as a function of the frequency, inductance and resistance of an electromagnetic coil (8) or of a magnetic coil winding (26), i.e. they can be optimised. 
<??>For this purpose, it is proposed that a current measuring device (10) with a current switch-off capability (11) be allocated in each case to a driver circuit (9) for the electromagnetic coil (8) and to a bridge circuit (27) for the stepping motor coil (26) and that digital control logic (12) be provided which generates a control signal (2), synchronised to a frequency transmitter (3) connected upstream, which control signal (2), alternately with the current switch-off device (11), acts as an on or off signal at the input (13) of the driver circuit (9) and of the bridge circuit (27).

Abstract: A method is provided for characterizing the spurious, time dependent magnetic field gradient response and for compensating therefor. In accordance with the method, two small sample objects are placed at two positions with respect to the system isocenter where the gradient to be compensated has different values. A magnetic field gradient pulse is applied to the sample, followed by the application after a variable time of a 90° radio frequency pulse. The phase of the resulting free induction decay (FID) signal is monitored as a function of total time since the end of the gradient pulse. These data are related to the impulse response of the gradient and are employed to construct compensation filters for both the gradient coils and the polarizing field shim coil.

Abstract: A modular, expandable, low-weight electric motor (10) has a cylindrical, non-magnetic casing (12) formed in axially-aligned sections (28, 30, 32). The casing sections (28, 30, 32) are releasably connected to define a unitary structure with a polygonal exterior surface (22) and a circular interior surface (24). Separate U-shaped stator pole assemblies (58, 84, 86) are releasably mounted against the exterior (24) of the casing (12), each casing section carrying the poles (62, 64) associated with a different motor phase. The poles (62, 64) extending through apertures into the interior of the casing (12), and have active pole faces (66, 68) which are curved and substantially flush with the circular interior surface (24) of the casing (12). A modular rotor (16) is mounted in the interior of the casing (12) and carries magnetic elements (114, 116) in axially spaced-apart sets corresponding to each motor phase. The active faces of the magnetic elements are curved and oriented in a cylindrical arrangement. During each rotation of the rotor (16), the pole faces of each motor phase simultaneously and repeatedly register with the associated magnetic element faces forming air gaps (110, 112), and the magnetic elements (114, 116) simultaneously complete local magnetic circuits (118) with each stator pole assembly. The sets of magnetic rotor elements (114, 116) are indexed circumferentially relative to one another such that the motor is self-starting.

Abstract: After a printer lid (2) has been opened, when a signal indicating that the lid (2) is closed again and a signal indicating that there is a sheet in a print mechanism (1) are received, the spacing or distance (Δh) between a print head (5) and the face of a sheet (P) held against a platen (8) is automatically adjusted to a desired value. Therefore, when a printing process is to be resumed after the lid (2) has been opened during printing operation, the spacing (Δh) between the print head (5) and the face of the sheet (P) is corrected even if the spacing (Δh) may have been varied due to physical contact to the print head (5) or a carriage mounting the print head (5) by the operator, so that desired print quality will be maintained after the printing process is resumed.

Abstract: An image forming apparatus comprises a memory (25) containing code data, code data input keys (12) and a preheat changeover key (11) for selectively switching a fixing device (81) to a preheat mode or an operation ready mode, whereby the apparatus is permitted to operate when a code data manually entered through the code data input keys (12) is identical with one of the code data already stored in the memory. The image forming apparatus further comprises entered code data release means adapted to be associated with the operation of the preheat changeover key (11) for switching the fixing device (81) to the preheat mode, so that the apparatus is brought to the state which prevailed before the code data is entered and where the apparatus is inhibited from operating. When the preheat key (11) is pressed, the apparatus is switched to the preheat mode and, at the same time, the entered code data is released. Accordingly, the apparatus requires no dedicated button or key for releasing the entered code data, and may put to practical use the preheat changeover means (11) which has been conventionally provided.
