Abstract: PURPOSE:To exactly remove excavated soil by a method in which spiral screw blades are provided to the peripheral side of a hollow shaft and a spiral band in parallel with the shaft is formed on the peripheral side of the blade in an auger head, and a bit to be closed when reversely turned is provided to the auger head. CONSTITUTION:An auger head 9 consists of a hollow shaft 5, a spiral screw blade 6, and a spiral band 30 provided to the peripheral side of the blade 6. Two left- and right-handed excavating bits 31 are pivotally supported on the tip of the blade 6 in a freely opening or closing (on a shaft 32) manner. A bottom plate 35 is also attached to the portion other than the lower end bit 31 of the head, and a synergestic mechanism such as stopper 36 is also provided to the bit 31 because the bit 31 is allowed to open during normal rotation but to close during reverse rotation.

Title: Transformer
Inventor: SAKATA YUKIMASA
IPC: H05B41/24
Filed: 1982-08-05
Abstract: PURPOSE:To obtain an output of detection signal for detecting DC field distortion by providing discontinuous part which generates leakage flux in the course of the closed magnetic path of iron core and by providing a field distortion detection coil in such a way as surrounding the closed magnetic path from the outside, in a transformer wherein a plurality of windings are wound to the iron core of closed magnetic path. CONSTITUTION:At the discontinuous part of a center leg 101, a leakage flux phir1 is generated, while at the discontinuous part of the side legs 102 and 103, a leakage flux phir2 is generated in the opposite direction to the leakage flux phir1. Thereby, a magnetic flux passing the inside of field distortion detection coil 113 can be obtained as the combined sum of vector. This magnetic flux alternates at a frequency of AC curent flowing through the winding 110-112 and thereby a voltage is induced to the field distortion detection coil 113. If magnetic flux circulating the iron core 1 is inbalanced, socalled DC field distortion occurs, magnetic flux crossing the detection coil 113 increases and an induced voltage becomes high. In this case, waveform of induced voltage is much distorted. By detecting increase of output of detection coil or distortion of output waveform, generation of field distortion can be detected.

Title: Packet majority decision circuit
Inventor: OKUYA AKIRA
IPC: H04N7/167
Filed: 1994-06-20
Abstract: PURPOSE:To improve a recognition rate as much as possible for a pakcet for which majority decision is to be performed even in the case of a C/N close to a service limit by changing a judgement value setting part for header identification by the time. CONSTITUTION:SDSC correction is performed to the pakcet after a mojority decision processing and the judgement value setting part 18 for the header identification is newly provided. When one pakcet for the majority decision is received, the set value of the judgement value setting part 18 for the header identification is made large while the packet is transmitted and the decrease of the number of reception packets due to the excessive errors of a header part is prevented. Thus, the packet is received even at the time of the C/N close to the service limit. That is, when the C/N is extremely low, since bit errors are too many and an error occurs in an SDSC correction part when the majority decision processing is not performed, the number of detection packets is increased some little and by performing the majority decision processing, the bit errors before performing the processing of the SDSC correction part are reduced as much as possible.
