Title: Burst signal demodulator
Inventor: YOSHIDA NAOMASA
IPC: H04L27/38
Filed: 1989-06-14
Abstract: PURPOSE:To reduce a preamble to nearly 1/3 of that of a conventional system by retarding an input burst signal for plural number of times with a delay means and estimating a bit timing, a carrier frequency and a phase from a data of a prescribed length. CONSTITUTION:One of signals digitized by an A/D converter 1 is inputted to a 1st delay means 3 and to a bit timing extraction means 4. The bit timing extraction means 4 estimates the bit timing from an input data of a prescribed length. The other data is inputted to a 2nd delay means 5 and inputted to a sampler 6. The sampler 6 extracts one sample data in the bit timing being most probable from N sample data for each modulation period in the timing estimated by the bit timing extraction means 4 and inputs the output to a carrier recovery means 7. The carrier recovery means 7 estimates the carrier frequency and phase from the input data of a prescribed length and recovers the carrier based on the estimated value.

Title: Digital signal reproduction circuit
Inventor: TANIYAMA TAKASHI
IPC: H03H21/00
Filed: 1987-06-19
Abstract: PURPOSE:To prevent a phase margin from being deteriorated due to the change of a frequency characteristic, by detecting the component levels of a digital signal in a prescribed frequency and in an area higher than that, comparing them with a reference level, and changing the coefficient value of a cosine equalizer when respective level is less than the reference level. CONSTITUTION:The initialization of said system is performed in such a way that the gain of a subtraction circuit 20 is adjusted so that the control voltage of a coefficient control circuit 24 can be set at, for example, a reference point A by using a reference tape recorded with a reference recording level. The coefficient of the cosine equalizer 13 is adjusted so that the high-pass compensation quantity of the equalizer 13 can be set at the optimum level by the control voltage at that time. When a tape whose high-pass area is attenuated lower than the reference tape is reproduced in such state, the subtraction circuit 20 performs an arithmetic operation, and the output becomes (+)potential, and the control voltage of the coefficient control circuit 24 is set higher than the point A in figure. As a result, the coefficient of the cosine equalizer 13 is increased, and the high-pass compensation quantity is increased corresponding to the value, and it is possible to prevent the phase margin from being deteriorated due to insufficient high-pass compensation.

Title: Rotary drum device
Inventor: KURIHARA NOBUSUMI
IPC: G11B5/52
Filed: 1993-06-24
Abstract: PURPOSE:To press a rotary drum against a fixed drum with a prescribed load without generating an eddy current in a motor yoke and to reduce the size of a device by providing an attracting magnetic circuit constituted of an attracting magnet and an attracting plate. CONSTITUTION:An attracting yoke 35 and the attracting magnet 36 are integrally stuck to a fixed drum 1, an attracting plate 38 is fixed to a rotary drum 9 through a spacer 37 and an attracting force is generated between both the drums with this attracting magnetic circuit. On the other hand, a magnetic circuit is constituted of a motor magnet 18, a rotor yoke 16 and a back yoke 23. When the current is allowed to flow through a stator coil 21, an electromagnetic force is generated in a motor rotor 19 since a magnetic flux runs through a stator coil 21 in the drum 9 and then the drum 9 is rotated. At this time, the eddy current is not generated in the yoke 23 since the rotor 19 and the yoke 23 are fixed to the drum 9. Further, the magnetic field of the attracting magnetic circuit does not affect a magnetic head 11 since the attracting yoke 35 is stuck to the attracting magnet 36. Therefore, size of the device can be also reduced.

Filed: 1994-07-05
Abstract: PURPOSE: To provide an insulated gate field effect device exhibiting ON-state resistance lower than that of ordinary IGBT and can be turned off through an insulated gate structure. CONSTITUTION: An insulated gate field effect device comprises a one conductivity type first region 3, an opposite conductivity type second region 4, and at least one region 8 for implanting opposite conductivity type charged carriers into one conductivity type first and third regions.

The second auxiliary region is isolated from the third region through the first auxiliary region and doped lighter than the first auxiliary region. When the implanted opposite conductivity type carrier current reaches a specified level, the pn junction 40b between the second auxiliary conduction channel and the second region is biased forward. Consequently, a bipolar transistor comprising the second auxiliary conduction channel and the first and second regions is conducted and thyristor operation being stopped upon removal of conduction channel is started in the implanted region.

IPC: G06Q50/00
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To enable a user to easily correct the patrolling destination and also to confirm a satisfied state of the constraint by calculating an out-of-stock period based on the total stock and the estimated demand value and displaying this calculated period against a patrol plan. SOLUTION: The latest balance sent to a central computer from an ATM is acquired. The estimated value and an estimation error of demand are read out of the estimation information 106. Then an out-of-stock date when the balance is smaller than a fixed amount is calculated from the balance and the estimated demand value, and the shortest out-of-stock date when the balance is smaller than a fixed amount is calculated from the estimated demand value including an error. Then a shortest estimated balance graph showing a period covering up to the shortest out-of-stock date is displayed together with an estimated balance graph showing a period covering up to the out-of-stock date. The next supply date is read out of the patrol information 107 and displayed against those balance graphs. The out-of-stock date or the shortest out-of-stock date is compared with the next supply date. Then a warning is displayed on a screen when the next supply date is later than the out-of-stock date or the shortest out-of-stock date.

Abstract: PURPOSE: To prevent the shift of the drop position for the tone arm by securing the admission of the tone arm from the 1st retaining position at the starting and repeating time of the record performance and then shifting the tone arm from the 1st to 2nd retaining position prior to the manual operation.  
     CONSTITUTION: Tone arm 3 is mounted to center axle 4 at nearly its centroid position via center holder 8, and fan-shaped slit plate 9 is fixed horizontally under axle 4 to be rotated along with the horizontal rotation of arm 3. At the same time, slits 9aW9c are formed radially from axle 4 and on the surface of plate 9 at the positions corresponding to the size of the record, and U-shaped drop position sensor 10 is fixed to plate 9. At the auto-playing time, arm 3 turns at position I set as the starting position and then shifts from position I to II at the manual operation time to give playing at position II as the starting point. As a result, the error of the drop position due to the slit width can be avoided.

Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To automatically specify an area similar to a sample by automatically acquiring features of the sample body through the learning of a hierarchical neural network and dynamically dividing the area according to its adaptability. SOLUTION: A pixel is specified first (S1) and an arbitrary image area including the specified pixel is determined (S3). Once the arbitrary pixel area is determined, an arbitrary border pixel C is determined (S5). When a pixel C is a pixel 1 present in the pixel area, the energy function value E is compared with the energy function value E when the pixel C is a pixel 2 outside the pixel area (S9). When the former is smaller than the latter, the pixel C is changed to the pixel 2 (S11). When the pixel C is not the pixel 1, the energy function value E is compared similarly (S13) and when the pixel 1 is smaller, the pixel C is changed to the pixel 1 (S15).
