Title: Trellis coding for modulation system
Inventor: BUEDATSUDO EMU AIUBOGURUU
IPC: H04L27/34
Filed: 1990-05-12
Abstract: PURPOSE: To make it possible to obtain a shape gain of about 1dB even by using a normal channel without complecating a code by mapping a digital sequence on a signal point sequence in order to transmit data through a normal response channel. CONSTITUTION: A discrete time type channel 10 is driven between the output of a trellis precoder 11 in a transmitter and the input of a decoder 13 in a receiver at the Baud rate of 1/T. In this case, mapping for transmitting data through a normal response channel is executed by selecting a signal point sequence from a subset of all usable signal point sequences based on a digital data sequence and a channel response. All the usable signal point sequences are included in a subset stored in a basic area for filtered trellis codes and the basic area is other than the simple Cartesian product in a finite dimensional region. Consequently, a shape gain of about 1dB can be obtained by a normal channel without complicating the codes.

Abstract: PURPOSE:To attain the recording with high density and the reproduction with high sensitivity by using a ferrite material to the surface which rubs a recording medium and providing a thin film having high saturation magnetic flux density and high permeability on the main magnetic path forming surface of a core. CONSTITUTION:A working gap 4 is formed vertically to a surface 3 which rubs a recording medium, and a ferrite core 1 is set opposite to the gap 4.

Title: Power circuit
Inventor: MUKAI KIYOTAKA
IPC: H02M3/335
Filed: 1978-10-03
Abstract: PURPOSE: To prevent the ocurrence of breakdown at the rectifying means by a system wherein temp. at the rectifying means being connected to the both ends of the secondary coil at the saturable transformer is detected, and the voltage applied from the feedback coil corresponding to each rectifying means is regulated.  
     CONSTITUTION: When an output partial-charge rate of a diode D 2  is higher than a diode D 3 , the temeprature of the diode D 2  becomes high. A heat-sensitive resistance element TH 1  detects the temeprature rise, and the resistance value increases. Consequently, applied voltage to a transistor Q 1  from a feedback coil N 3  decreases, the conductivity of the transistor lowers and the output of secondary coil N 2  at the half-wave time of the transistor decteases. Thus, the load-charge voltage of both diodes can be equalized, and the temperature rise of both diodes can be equalized or brought to not more than the allowable temperature.

Abstract: PURPOSE:To enable the formation of a rotor iron core of any thickness when the outside diameter of the rotor iron core is the same and to prevent the generation of fins, by forming conductors and end rings while the rotor iron core is held in place under pressure between the 1st and the 2nd molds. CONSTITUTION:A rotor iron core 5 is inserted to the inside of a guide 14, and is placed on a bottom mold 4. Forming molds 1 are thereafter clamped and a top mold 2 descends until it comes into tight contact with the top surface of a middle mold 3. On the other hand, a bottom mold 4 ascends and a curved plate 15 enters the inside of a deep groove 13 until it contacts the bottom surface of the mold 3. Then, the core 5 receives the pressing force of a hydraulic cylinder or the like which is a driving source for moving the same upward. The core is thus strongly held in place under pressure between the mold 3 and the mold 4. The melt of Al in this state is forcibly fed into a cavity 7 through a runner 9 and a sprue 10; further, the molten metal is forcibly fed into a cavity 12 through the closed slot 5a of the core 5. Thereafter, the molten metal is cooled to solidify, whereby conductors 18 and end rings 6, 11 are formed.

Title: Manufacture of magnetic powder made of acicular ferromagnetic iron oxide
Inventor: TAKAGI SHIYUUICHI
IPC: H01F1/11
Filed: 1984-06-19
Abstract: PURPOSE:To provide magnetic powder made of acicular ferromagnetic iron oxide which has large coercive force and saturated magnetization and extremely small variation of magnetization with time, by a method in which, after acicular gamma-Fe2O3 particle surfaces are coated with iron oxide layers containing zinc and bivalent iron and cobalt compound layers, they are heat-treated in an inert gas atmosphere. CONSTITUTION:After acicular gamma-Fe2O3 particle surfaces are coated with iron oxide layers containing zinc and bivalent iron and cobalt compound layers, are dehydrated and dried, they are heat-treated at a temperature of 100-250 deg.C for a time from 30 min-3hr in an inert gas atmosphere. As the inert gas, nitrogen, argon, or neon, etc. is preferable to be utilized, but nitrogen can be pratically used, which is low cost and can be easily available. Variation of coercive force Hc of the magnetic powder made of acicular ferromagnetic iron oxide produced in this way with time is extremely small. When a ratio Zn/Fe<2+> of zinc to bivalent iron being contained in the iron oxide layers, which is important, is 8-25atom%, magnetic powder having large saturated magnetization can be produced, thereby enabling the increase of obtained saturated magnetization value sigmas of magnetic powder.

Filed: 1988-05-20
Abstract: PURPOSE:To reduce a power loss and miniaturize a device and lower a cost by connecting current detecting means to the respective three power elements on the lower arm side, in parallel with each other. CONSTITUTION:Current sense MOSFETs Q7, Q8 and Q9 are activated on the same timing as that of corresponding power MOSFETs Q2, Q4, and Q6 on the lower arm side, and to corresponding detecting resistors Rs1, Rs2 and Rs3 for diverting main current, detecting current is permitted to flow. When overcurrent is generated on the power MOSFETs Q2, Q4 and Q6, then voltage drop detecting point SU, SV and SW potentials acoording to the power MOSFETs are turned higher than reference voltage Vref1. Then, the output of comparators COM1, COM2 and COM3 according to the potentials comes to a level 'H', and accordingly, the output of logical sum logics OR1, OR3, also comes to a level 'H', and abnormal state signal Fault is issued. Because of a composition for diverting the main current as mentioned above, a power loss for detection is sufficiently reduced.

Abstract: PURPOSE:To reduce the error for decoding and simplify the constitution of hardware of a high-density recording system, by converting a binary data string to a four-bit code by a prescribed algorithm. CONSTITUTION:Two-bit data is converted to a four-bit code in accordance with the algorithm of the S1 conversion table. (In the S1 conversion table, A-D are four kinds of pattern constituted by two-bit patterns, and Y is the complement logic of OR of the two-bit code just before a code Y, and En is a data bit of n bits before two-bit data in the two-bit data string, and Ln is a data bit of n bits after two-bit data similarly.) That is, in case that the binary data string is separated into every two bits and is converted to four-bit data, it is converted identically in accordance with patterns within four bits before and after a two-bit pattern to constitute a code sequence where 2-8 code 0s exist between a code 1 and the next code 1, and thus, the occurrence of errors is reduced at the decoding time, and the constitution of a high-density recording device is simplified.
