Title: Fet type photodetector
Inventor: HIROKI TAMAYO
IPC: H01L31/0352
Filed: 1989-11-14
Abstract: PURPOSE:To improve a time response, to accelerate a responding speed and to improve sensitivity by laminating an active layer in which source, drain and gate electrodes are mounted on a buffer layer having an energy band structure including a wider band gap than that of the layer and becoming a barrier for carrier. CONSTITUTION:A p-type Al0.3Ga0.7As buffer layer 15 is laminated on a semi- insulating GaAs substrate 16, and a n-type GaAs active layer 14 is further laminated thereon. Since the AlGaAs has wider band gap than that of the GaAs, the layer 15 becomes a barrier for the layer 14 and the substrate 16. An Au/Ge/ Au source electrode 11 and a drain electrode 13, an Al gate electrode 12 are mounted on the layer 14. The layer 15 does not absorb a light having 830nm of wavelength, and does not deteriorate a time response characteristic. Since carrier is confined by n-p hetero junction of the layers 14, 15, its pinch-OFF characteristic is improved, and a photocurrent is scarcely leaked to the substrate.

Filed: 1991-11-11
Abstract: PURPOSE:To provide a low-cost steering column of a good operability by using a simple transmission mechanism comprising a drive gear, a driven gear, and a link, and moving a telescopic tube in the axial direction to the front in rotating a tilt bracket up. CONSTITUTION:When fixture by a fixing means 40 is released, a backup plate 43 rotates clockwise to rotate a pole 42 counterclockwise through engagement of a cam protrusion with a pin 42a.

IPC: B24B41/06
Filed: 1993-10-29
Abstract: PURPOSE:To simply and accurately perform the centering of a wafer by putting the wafer in a rotating ring, pressing the outer circumferential section of the wafer by each contact shoe with the rotating ring rotated, and thereby performing centering. CONSTITUTION:When a wafer comes in, which has been sucked in by vacuum by the sucking section of a wafer carrying means, a rotating ring 4 is rotated first, and three contact shoes 46 approach to the circumferential section of the wafer so as to come in contact with the wafer. In this case, the ring is conditioned to a free rotation, and if the wafer is off-centered, the wafer is brought close to the direction that its center agrees with the center of the rotating ring 42, so that centering is thereby performed. The vacuum suction of the wafer is then released, a second center ring is then rotated in this case, three each of second contact shoes approach to the circumferential section of the sucking section so as to be in contact therewith. In this place, since the ring can be freely rotated, if the wafer is off-centered, its sucking section is brought close to the direction that its center agrees with the center of the rotating ring, so that centering is thereby performed.

Abstract: PROBLEM TO BE SOLVED: To enable the retrieval of recorded data information to be performed with high accuracy at a high speed and the reproduction to be performed with a high BER. SOLUTION: Signal light 5 of P polarized light holding the first data information is recorded as a first hologram on the optical recording medium 10 by reference light 6 of the P polarized light. Next, signal light 5 of P polarized light holding the second data information in the state of subjecting the first data information to an encoding processing is recorded as a second hologram by the reference light 6 of S polarized light in the region of the optical recording medium 10 where the first hologram is recorded. This region is irradiated with the signal light 5 of the P polarized light holding the retrieval data information at the retrieval.  At this time, the P polarized light component indicating the correlation between the first data information and the retrieval data information and the S polarized light component indicating the correlation between the second data information and the retrieval data information are simultaneously obtained as diffracted light 7 on the optical path of the reference light 6. The P polarized light component 7P in this diffracted light 7 is detected by a photodetector 43. The region described above is irradiated with the reference light 6 of the P polarized light at the reproduction.

Abstract: PURPOSE:To obtain excellent memory characteristic by forming so that an interval of one set of gate electrode layers to be formed in a memory cell array region becomes substantially equal to that between the gate electrode layer formed on a peripheral circuit region and a dummy wiring layer. CONSTITUTION:A dummy pattern 6d is formed on a part of a wide wiring pattern interval of a peripheral circuit part so that the density (interval) of a wiring pattern on the peripheral circuit part is substantially the same as the wiring density (interval) of a memory cell. As a result, a conventional problem in which the position of the same designing size is finished in a different size by a loading effect at the time of photoengraving process and etching is solved. Since the dimension accuracy of the peripheral circuit part is improved, a gate electrode 6b having a size near a designing size value can be obtained. Thus, since the size accuracies of the memory cell and the peripheral circuit part are uniform, dimension controllability as the entire DRAM is improved.
