Title: Demodulator for amplitude deviation keying signal
Inventor: SERUGIYUU SHIRUBIAN
IPC: H04L27/06
Filed: 1990-08-03
Abstract: PURPOSE: To accurately demodulate the amplitude deviation keying by using an edge detector, a phase detector, a filter, a sampling allowance circuit, an integrator, a voltage pulse width converter and a local clock signal generator. CONSTITUTION: An amplitude deviation keying ASK input signal inputted to an edge detector 54 is inputted to a filter 58 via a phase detector 56, and a phase error signal A is outputted. A sampling allowance circuit 60 measures the AM demodulation signal via the threshold Vref in every cycle of an fO clock signal and then produces a positive strobe signal STR when a carrier signal is included in an ASK signal. Then a signal A is transferred to an integrator 62 by the signal STR, and a signal B is outputted to a voltage pulse width converter 64 from the integrator 62. Thus, a pulse output signal F is applied to a local clock signal generator 66 from the converter 64. The phases of clock signals 2fO and fO are deviated in the direction where the phase difference between both signals is minimized.  The signal fO has the synchronization of phase with the carrier signal and can accurately demodulate the ASK signal.

Inventor: HARINE MAKOTO
IPC: C23C8/80
Filed: 1987-08-20
Abstract: PURPOSE:To remove the carburized layer of the part of a carburized and hardened member requiring the removal of the carburized layer by machining in a simple and sure manner, by tempering only the part by high frequency induction heating to lower the hardness. CONSTITUTION:A member such as a gear or a sliding member is carburized to obtain a member 1 having high surface hardness and high internal toughness. Only the part 2 of the member 1 requiring the removal of the carburized layer is tempered by heating with a high frequency induction heater and by cooling to lower the hardness of the part 2. The carburized layer 6 of the part 2 is then removed, forming a part freed of the carburized layer.

Title: Method and device for image transformation
Inventor: NAKAGAWA TETSUYA
IPC: G06T3/00
Filed: 1989-08-11
Abstract: PURPOSE:To easily execute strict consideration based upon a sampling principle by adaptively executing the interpolation filtering processing and thinning filtering processing of input discrete data in both of two processing processes. CONSTITUTION:Processing for finding out respective grating point data on an intermediate image can be executed by resampling texture data by using the grating point interval between respective grating points on the intermediate image reversely formed on an one-dimensional texture data. Thereby, the consideration of folding distortion based upon the sampling principle can be attained in each grating point on the intermediate image. Thereby, when an ideal low pass filter (LPF) whose amplitude is '1' when cut-off frequency is <=fc, ideally '0' in the case of the cut-off frequency <=fc, is used as the LPFs 12, 13 to be used for interpolation or thinning, interpolation processing or thinning processing logically including no distortion can be considered. Thus, extremely accurate interpolation or thinning can be attained by using ideal LPFs as the LPFs 12, 13.

Title: Image compressing/expanding circuit
Inventor: MATOBA NARIHIRO
IPC: H04N1/415
Filed: 1992-08-03
Abstract: PURPOSE:To shorten the processing time by using a circuit which is suited to a fixed length coding system which divides an original image into small areas of each prescribed size when the image information on the original image is compressed and stored and then codes the image information into the data of the fixed length for each divided area. CONSTITUTION:The data have the fixed length for each block and therefore can be easily coded and encoded for each block. In other words, both a coder 12 and a decoder 16 can simultaneously read the shifted lines to reduce the burden of a CPU when the first line of a small area is read. Thus the processing speed is increased owing to a fact that both coding and encoding operations can be simultaneously carried out for each color.

Title: Digital signal reproducing device
Inventor: YOKOZAWA SEIICHI
IPC: G11B5/09
Filed: 1986-09-05
Abstract: PURPOSE:To prevent malfunction that signal detection by an on track causes by inhibiting the detection of a sync signal if the level of the frequency component of a pilot signal included in an output signal from each rotating head is not in the prescribed relation. CONSTITUTION:A BPF 101 passes by only the component at 130kHz of a signal RF from the rotating head through a reproduction amplifier 15. An envelope detector 102 converts the amplification level of the component at 130kHz into a level DC, which is impressed on the one input of a comparator 107. When a prescribed level that a semifixed resistance VR sets is higher than the output level of the detector 102, the comparator 107 outputs a signal OK at a level H: otherwise, the comparator 107 decides the pilot signal of the on track. Consequently, if the output of the comparator 107 is L, the sync detection of a sync detection circuit 202 is inhibited. Thus the disturbance of a capstan servo is prevented which the mistaken detection of the pilot signal by the on track causes.

Title: Monostable multivibrator
Inventor: SUGIHARA TAKANORI
IPC: H03K3/033
Filed: 1983-11-08
Abstract: PURPOSE:To attain a clearing action through a monostable multivibrator by applying an input signal to a clock terminal of a D type FF and providing a delay circuit between a reset terminal and an output terminal of said FF. CONSTITUTION:A D type FF7 is provided together with a delay circuit 8 and an AND gate 9. The circuit 8 consists of inverters 10 and 11, resistances 12 and 14, a capacitor 13, etc. When an input signal IN is changed to a high level from a low level, the output Q' of the FF7 is changed to a low level from a high level. Therefore the potential of a node N3, i.e., the output of the inverter 10 rises up gradually by a time constant of the capacitor 13 and the resistance 12, respectively. When the potential of the N3 reaches the threshold value of the inverter 11, the output of the inverter 11 is inverted to a low level from a high level. As a result, the potential of a reset terminal R of the FF7 is set at a low level. Then the output Q' is changed to a high level from a low level, and the non- reverse output Q is changed to a high level from a low level. The output Q is used as an output OUT to obtain an output of a desired pulse width.
