Title: Excavation bit
Inventor: SHOJI TADASHI
IPC: E21B10/46
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To prevent the falling of a bit from a truncated conical portion of a tip by sequentially and coaxial arranging the main body of a bit in one united body comprising a shaft portion for installing, a disc-shaped collar portion and a truncated conical portion having a first and a second tip attaching holes. SOLUTION: A cylindrical portion 26L and a disc portion 26U of a tip 2 are respectively fixed in holes 16L and 16U of a tip mounting hole 15 of the main body 1 of a bit in configuration. Then, when excavating a quay-wall or an earten wall, a tip 2 is made with a hard material for reducing wear. Also for the main body 1 of a bit, it has a low hardness compared to the tip 2, so that the head-chopped conical portion 13 wears from the side of the upper end face 14, and this wear exceeds the initial depth of the hole 16U. Therefore, the head-chopped conical portion 13 wears starting from the surroundings of the hole portions 16U, and even though an insertion unsolidified state occurs inside the hole 16U of the disc portion 26U, the disc portion 26U inside the hole portion 16U changes to a fixed insertion state.  By doing this, the falling of the tip 2 from the truncated conical portion 13 of the main body 1 of the bit can be prevented.

IPC: B24B5/06
Filed: 1987-02-04
Abstract: PURPOSE:To control a swivel angle accurately and quickly by making a grinding wheel swivel about a swivel pivot by means of an actuator consisting of a pair of piezoelectric elements with their tips contacting both side edge portions of the wheel spindle stocks. CONSTITUTION:Based on a preset control program, a headstock 2 and a wheel spindle stock 10 are moved to slide by means of motors 8 and 13 and the peripheral surface of a grinding wheel 11 is brought into contact with the inner circumferential surface of a workpiece 5 to be ground to perform a grinding process. At the same time, a swivel control signal corresponding to the amount of deflection of a wheel spindle 12 occurring at the time of the grinding process is outputted from a control means 16. Based on the swivel signal, swivel control sections 17 and 18 control the wheel spindle stock 10 to a swivel angle corresponding to the control signals by applying voltages to a pair of piezoelectric elements 14 and 15 so that the voltages are either increased or decreased opposite to each other and that the stock 10 swivels about a swivel pivot 9. In this way, a cut-in angle of the wheel can be set to an optimum condition quickly and accurately according to the amount of deflection of the wheel spindle caused at the time of the grinding process.

Title: Optical element
Inventor: JERUMII BURROWS
IPC: H01L31/0352
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To make the applied potential to the input portion of an optical element affect its free-carrier distribution, by providing the optically operable element in one or more predetermined regions of which free carriers are induced in response to its incident electromagnetic wave. SOLUTION: When applying respectively predetermined potential to first and second input terminals 7, 9, they induce respectively on associated first and second ends 11, 13 of a second quantum bar 5 the charges whose polarities are opposite respectively to the corresponding potential polarities applied to the respective input terminals 7, 9. Therefore, the charge in the first end 11, becomes relatively negative and the second end 13 positive.  Then, the induced inverse-polarity charges of a first quantum bar 3 from the second quantum bar 5 are transferred respectively to the first and the second output terminals 19, 21 to make the potential of the first output terminals 19 negative correspondingly to the relatively positive charge of a first end 15 of the first quantum bar 3, and to make the potential of the second output terminals 21 positive correspondingly to the relatively negative charge of a second end 17 of the first quantum bar 3. Therefore, there can be obtained an optical element whose input voltage not larger than 1V in its ON-state suffices to operates it and in which no stationary current flows, thereby making very low consumption power.

Title: Data reproduction circuit for floppy disk device
Inventor: TSURUTA KENJI
IPC: G11B5/09
Filed: 1988-02-05
Abstract: PURPOSE:To surely perform the peak detection of a reproducing signal by providing a pulse output means to output a pulse signal corresponding to the zero cross point of a differential signal whose phase is shifted by a phase control means. CONSTITUTION:A phase control circuit 14 outputs a signal C with a waveform in which the peak of the differential signal B outputted from a differentiation circuit 13 is delayed by a prescribed time T. A comparator 15 generates the pulse signal P whose level changes at the zero cross point of the signal C whose phase is controlled by a phase control circuit 14, and a rapping circuit 16 generates read data RD obtained by the form arrangement of the pulse signal P from the comparator 15. Thus, since the read data RD is reproduced based on the phase control signal C in which the peak of the differential signal B is shifted, a state where the timing of the peak of the reproducing signal A with the peak of the read data RD is shifted compared with an on-going case is generated, and thereby, it is possible to prevent the state where the peak of the reproducing signal A coincides with that of the read data RD from being generated.
