Title: Electronic circuit
Inventor: SHIMIZU SHIYOUICHI
IPC: H03F3/45
Filed: 1984-06-26
Abstract: PURPOSE:To reduce an output offset voltage by giving a difference voltage in advance to a gate voltage of a differential FET causing an offset. CONSTITUTION:The drain of differential FETs Q1, Q2 is connected to a power supply VDD via load resistors RL1, RL2 and the source is connected to a common constant current source I1. The drains of bias FETs Q3, Q4 are connected in common and the sources are connected respectively to other constant current source I0 and gate of the FETs Q1, Q2. Then the gates of FETs Q3, Q4 are biased to the same potential. Since the FETs Q1, Q2 and FETs Q3, Q4 are manufactured back to back similarly in one mask, even when an offset due to mis- aligned mask is caused between the FETs Q1, Q2, the charactetistic of the FETs Q3, Q4 is different similarly and a bias applied to the gate is fluctuated and the offset of the output voltage is reduced.

Title: Formation of multilayer wiring construction
Inventor: TSUBOUCHI NATSUO
IPC: H05K3/46
Filed: 1979-10-09
Abstract: PURPOSE:To obtain the multilayer wiring free from disconnection by stacking an amorphous Si layer including impurities on an Al or Al alloy layer, selectively oxidizing the layers with a mask and piling the Al or Al alloy layers together with the removal of the mask. CONSTITUTION:The amorphous Si 8 and Si3N4 9 are formed on Al 3 and 3' at a low temperature by plasma CVD method. A film 9 is selectively etched to make a mask 9' and Si 8 is oxidized at a temperature below the melting point of Al by plasma anode oxidiation method or the like to be converted into Si3N4 4'. With the removal of the mask 9', the second Al wiring layer is laminated thereon. As the amorphous Si 8 at the through hole part is connected to the Al layer to form a flat construction with no step, disconnection can be avoided at the part. The use of a phosphoric acid-based etching liquid after the etching of Al allows selective etching of Al layer 7 alone thereby improving the float level of the through hole part. The resistance value of the amorphous Si can be lowered by adding impurities thereto properly.

Title: Controller of pickup
Inventor: KUSAKA SATORU
IPC: G11B21/03
Filed: 1980-09-20
Abstract: PURPOSE:To correct both a tracking error and a time axial error, by storing the change of the eccentric extent of a disk while it turning one round and then controlling the point of detection of a pickup with the stored signal when the signal is reproduced. CONSTITUTION:Detectors 2 and 3 are set with a space smaller than the width of a bit 4 containing a photodetector formed on a track on a disk for example. Then the light is irradiated to the detectors to obtain signals. If a tracking error exists, the phase of output has a shift between the detectors 2 and 3 to obtain pulses PA  and PB having inversion of phases with a half turn of the disk through waveform  shaping circuits 5 and 6. With these pulses, a sine wave output S of a period per  one round and a signal having a delay of pi/4 obtained via an up-down counter 8  and a D/A converter 9 respectively are stored. After this, the output signal is separated into a tracking error and a time axial error to be compared with the stored  signal with each point of the same phase of revolution of the disk. Thus the position of a photoelectric transducer is controlled toward both the circumference and  the diameter of revolution. In such way, both the tracking and time axial errors are  corrected.

The measured values are stored 16 and the centroid of the bead is determined from the measuring points on the inner side of the bead. The distances from the determined centroid to the respective measuring points are computed and the radius of the circle of the same circumferential length as the length l1 is determined. The distances from the radial point of the true circle determined from the centroid up to the respective measuring points are compared and computed 17.

Title: Manufacture of semiconductor device
Inventor: FUJIMURA SHUZO
IPC: H01L21/22
Filed: 1987-05-29
Abstract: PURPOSE:To enable a semiconductor substrate to be manufactured on the industrial base by a method wherein, in the doping process, a layer containing specific dopant is provided on the surface of a semiconductor and then the layer is irradiated with a plasma downward to permeate the semiconductor with the dopant simultaneously controlling the amount of the dopant. CONSTITUTION:A source layer 2 is provided on a semiconductor substrate 1 such as an Si substrate etc., and then the semiconductor is permeated with a dopant by exposing the source layer 2 to plasma to provide a diffused layer 4. At this time, assuming the impurity concentration in the source layer 2 to be constant, the thinner the film thickness of the source layer 2, the more the led-in amount and the higher the concentration in the diffused layer 4. Besides, assuming the impurity concentration in the source layer 2 to be constant, despite the thicker the layer thickness, the more the total amount of dopant undoubtedly, the diffused layer 4 becomes a low concentration layer. At this time, judging from the fact that the concentration of gas component is recognized to increase in the source layer 2, it is presumable that the energy is given off in the source layer 2 when the source layer 2 is irradiated with plasma and then plasma source is restored from the excited state to the normal state to make the semiconductor substrate 1 permeated with the dopant.

Consequently, it is possible to simplify a structure without necessitating an elevator because a vehicle is moved between the bogie and the storage part, improve carry-in/out speed, and use the storage part efficiently because an empty storage part for carry-in/out of the vehicle is not required.  Moreover, only one bogie is used so that its number can be greatly reduced. Furthermore, the installation of the bogie in each storage part becomes unnecessary because a pallet side travel device is provided on the bogie.
