Title: Degraded starch and its production
Inventor: ROBERUTO FUREDERITSUKU TOOMASU
IPC: C08B30/12
Filed: 1988-02-29
Abstract: A destructurized native starch material is described which has a water content in the range of about 10 to 25 % by weight and that its mass average molar mass is reduced by a factor of 2 to 5000 compared to its original mass average molar mass. The destructurized starch is produced by heating a chemically non-modified starch material having a water content in the range of about 5 to 25 % by weight of the total weight of the composition in the presence of a chain scission catalyst in a closed volume to an elevated temperature sufficient to form a thermoplastic melt and until the mass average molar mass is reduced by a factor of 2 to 5000.

Title: Antenna for high frequency communication
Inventor: UEHA YOSHINOBU
IPC: D06M101/40
Filed: 1988-02-25
Abstract: PURPOSE:To improve the antenna efficiency with light weight by using a specific conductive high polymer member for the conductor part of the antenna or the structural member of the antenna main body. CONSTITUTION:The conductive member made of a conductive high polymer material whose conductivity is >=10<4>S/cm and whose specific gravity is nearly <=2.3 is used for the conductor part of the antenna or the structural member of the antenna main body. Since the antenna efficiency of the high frequency communication antenna using the conductive high polymer member as above is improved more than a conventional high frequency communication antenna, the size of antenna is reduced more than the conventional antenna size. Thus, the weight of the high frequency communication antenna is reduced, and the high frequency communication antenna with excellent antenna efficiency and ease of handling is obtained.

Title: Controller of power converter
Inventor: KATAOKA AKIO
IPC: H02M7/155
Filed: 1983-03-16
Abstract: PURPOSE:To reduce low order harmonic current components by varying the sharing rate for energizing by two switching means of other side in response to the magnitude of an output voltage of a full-wave rectifier using switching means at full arms of positive and negative sides. CONSTITUTION:A full-wave rectifier which has gate turn-OFF thyristors (GTO) G1-G6 and reverse voltage blocking diodes D1-D6 is connected to AC power sources EU-EW, and the voltages are supplied to an inductance L and a resistor RL of load side. A comparator 1 obtains a deviation between a current command IC and a DC feedback current INF, applies to a gate signal generator 2, and the generator 2 applies a gate signal to GTO G1-G6 from information fs of a power source voltage. The sharing rate for energizing is altered by other two GTOs in response to the magnitude of the output voltage. The ratio of the period that the output voltage is generated to the pulse period is represented by the conduction rate, and when the conduction rate is 0, the sharing rate is set to 0.5, and when the conduction rate is 1.0, the sharing rate is set to 0.3-0.4, thereby reducing the fifth or seventh harmonic waves.

Title: Coaxial cylinder type torque limiter
Inventor: FUJIOKA TERUO
IPC: G05D17/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a coaxial cylindrical type torque limiter to effect smooth rotation. SOLUTION: A semirigid magnetic substance 1 has a joint J1 axially inclined to the left at an inclination angle α and pressed in the inner periphery of a rotary cylinder. A permanent magnet 2 is magnetized such that the magnetization regions of an N-pole and an S-pole inclined rightward at an angle β with an axial direction are alternately formed in a peripheral direction, and brought into adhesion to the outer periphery of a rotary shaft. A rotary shaft and a rotary cylinder are coaxially fixed such that the semirigid magnetic substance 1 and the permanent magnet 2 are positioned facing each other with a gap. Rotation is transmitted between the rotary shaft and the rotary cylinder by hysteresis torque generated between the semirigid magnetic substance 1 and the permanent magnet 2.  Thus, the fluctuation of the hysteresis torque when a boundary between magnetic poles passes the joint part of the semirigid magnetic substance is reduced and the occurrence of unevenness in rotation is suppressed, whereby sufficiently smooth rotation is practicable.
