Abstract: PURPOSE:To reduce the leakage current to such extent that it becomes negligible by forming the laminar structure on a semiconductor substrate, which is composed of a semi-insulating first semiconductor layer, a second semiconductor layer of the first conductive type whose forbidden band gap is narrower than that of the first semiconductor layer, a third semiconductor layer of the first conductive type whose forbidden band gap is wider than that of the second semiconductor layer and forming P-N junctions in the second and third semiconductor layers. CONSTITUTION:On a GaAs substrate 13, an undoped AlxGa1-xAs layer 17, undoped GaAs layer 3 which is to be an active layer, and Se doped N-type AlxGa1-xAs layer 4 are grown in order by epitaxy using an organic metal gas-phase growth technique. On the grown layers, an SiO2 or SiN film is deposited and a predetermined region is removed by etching into stripe form to expose the surface of the grown layer. Zn is diffused to form a Zn diffusion region 5. After the above SiO2 or SiN film is removed by etching into stripe form of 10mum, a P-type electrode and an N-type electrode are arranged on the Zn diffusion region 5 and the non-diffused electrode, respectively.

Title: Data alignment system for dma transfer
Inventor: YAZAKI NAOFUMI
IPC: G06F13/28
Filed: 1991-09-10
Abstract: PURPOSE:To freely set a transfer size, and to shorten a transferring time by using the transfer information of a block by setting a transfer leading address, number of transfer words, and furthermore transfer size at an array table being the transfer information of an array chain mode. CONSTITUTION:When the leading address of data to be transferred is not the multiple of the data length of a main bus 6, an MPU 1 divides the transfer data into plural blocks so that the leading address can be the multiple of the greatest common divisor of the data length, and sets an array table 4 at each block, before transmitting the command of a DMA activation to a DMA controller 5. After the array table is set, the MPU 1 transmits the command of the activation of the DMA transfer in the array chain mode. Thus, the array table 4 is functioned as a means which applies the transfer information of the DMA transfer in the array chain mode. The DMA transfer is operated in the same way even when the number of transfer bites is not the multiple of the data length of the main bus 6.

Abstract: PURPOSE:To enable efficient and quick processing for automatic remeasurement, by automatically selecting a sample for remeasurement requiring dilution to perform an automatic dilution. CONSTITUTION:When a computer 9 judges that a sample requires remeasurement by being diluted as the absorbance of samples reaches the limit value of the measuring absorbance of an analyzer at the first measurement, the sample involved is sent to the nozzle position of a sample distribution/dilution device 10 with a sample disc 2. Then, it is distributed with a nozzle of the device 10 as remeasuring sample and the nozzle stops on a dilution container 12 of a dilution disc 11 and then, lowers. After the lowering of the nozzle, the sample is discharged from the nozzle together with a dilution liquid by the device 10. The disc 11 having the remeasuring sample automatically diluted moves sequentially and then, stops at the position of a sampling nozzle 4 as an analyzer, where the remeasuring sample requiring dilution can be done efficiently and quickly by automatic selection and automatic dilution thereof.

Title: Propeller shaft made of fiber reinforced resin
Inventor: NAKANOU YOSHIFUMI
IPC: F16C3/02
Filed: 1990-08-30
Abstract: PURPOSE:To obtain a propeller shaft with high productivity and light weight which transmits large torque by a method wherein a fiber reinforced resin (FRP) tube is an outer cylinder, an inner cylinder made of resin joined with a coupling element is provided on one end and the inner and outer cylinders are joined with each other by a tube-in-tube method. CONSTITUTION:A layered structure of an FRP tube 1 of a propeller shaft is designed so that the FRP tube 1 largely shrinks in a peripheral direction when torque functions. Since a shrink amount in the peripheral direction of the outer FRP tube 1 is larger than that of an inner steel pipe 2, compression force occurs on rubber 5 between the inner and outer tubes 1, 2. Since the compression force of the rubber 5 increases in proportion to applied torque, it is possible to delay adhesion fracture shear fracture of the rubber 5 thereby increasing transmission torque. Therefore the same amount of torque can be transmitted by approximately 2/3 to 1/2 length of overlapped length of the conventional inner and outer cylinders 1, 2.

Title: Water level controller for hopper
Inventor: TAMURA TAKUHIRO
IPC: G05D9/00
Filed: 1988-09-14
Abstract: PURPOSE:To stabilize the water system on the upstream side of a hopper and, at the same time, to quickly cope with the fluctuation of the water level in the hopper by controlling the capacity of a pump to an intermediate capacity between the pump capacity when a low water level is detected and the one when a high water level is detected. CONSTITUTION:The flow rate of water to a hopper 1 is controlled to an aimed quantity by adjusting the opening of a flow rate control valve 6 while the flow rate is detected by means of a flow rate sensor 5. The water level in the hopper 1 is detected by means of water level detecting means 2 and 3 and, when a low water level is detected, the flowing-out quantity of the water from the hopper1 1 is decreased by lowering the capacity of a pump 9. When a high water level is detected, on the other hand, the flowing-out quantity is increased by raising the capacity of the pump 9. Thus the water level is varied between the low and high levels and, after the capacities of the pump 9 to the low and high water levels are recognized, the capacity of the pump 9 is controlled to an intermediate level. Therefore, the fluctuation of the water level can be coped with quickly and the water level can be stabilized to the intermediate level.

Abstract: PROBLEM TO BE SOLVED: To make it possible to adequately assure the shape and function as a liquid crystal cell by superposing both electrode substrates on each other via spacers of a large diameter and small diameter and pressurizing both electrode substrates until the spacing therebetween is reduced to the diameter of the small-diameter spacers after injection of liquid crystals. SOLUTION: The spacers 30a of the small diameter and the spacers 30b of the large diameter are respectively sprayed onto the surface of the color filter substrate 10 and the counter substrate 20 is superposed on the color filter substrate 10 via both spacers 30a, 30b and a seal 40, by which an empty cell is formed. The seal 40 is then cured by baking while load is applied thereon in such a manner that the cell gap attains about 5μm which is the diameter of the spacers 30b. The substrates are then arranged in a vacuum state and the smectic liquid crystals are injected into the empty cell. The gap of the liquid crystal cell is held at 5μm by the spacers 30b. The pressure is thereafter applied by a pressurizing jig on both substrates 10 and 20 to deform the spacers 30b so that the cell gap of the liquid crystal cell is held uniformly at 2μm only by the spacers 30a.
