Title: Reduction of 1/f noise of heterojunction bipolar transistor
Inventor: UIRIAMU UEI CHIYUNGU RIU
IPC: H01L29/08
Filed: 1993-07-12
Abstract: PURPOSE: To reduce low frequency noise in base-emitter junction space charge region by a structure wherein an emitter region has a mesa part and a shelf part thinner than the mesa part with the mesa part being spread over a part of a base region on the outside of the mesa part. CONSTITUTION: A collector area 3 is formed epitaxially on a subcollector 1. Similarly, a base layer 5 is formed on the collector layer 3 followed by formation of an emitter layer 7 and an N type layer 8. Subsequently, an emitter metal 9 is deposited partially on the surface of the N type layer 8 and used as a mask for forming a shelf part 11 and a mesa part 13. Finally, a resist layer 15 on the shelf part 11 is removed by etching while leaving a part thereof until the base layer 5 is reached. Consequently, the shelf part 11 of emitter is spread on the surface of the base and noise characteristics can be improved for both low frequency and high frequency.

Abstract: PURPOSE:To easily control by forming a levitation unit of a superconductor, and disposing the superconductor in a specific region of magnetic field of magnetism generating means. CONSTITUTION:A centrifugal separator having a magnetic levitation unit is composed of an electromagnet 2 as magnetism generating means fixed to a frame 25, a ringlike superconductor 3 disposed directly under the electromagnet 2, a coupling 4, a high speed rotor 5 supported to the lower part of the coupling 4, and a hysteresis motor 6.

Title: Magnetic video recording and reproducing device
Inventor: USUKI NAOJI
IPC: G11B5/027
Filed: 1985-08-02
Abstract: PURPOSE:To reduce number of channels by erasing an undesired recording track just after the 1st and 2nd recording/reproducing heads make recording and starting the recording by the 1st recording/reproducing head afterward. CONSTITUTION:In recording a PCM sound signal, a magnetic tape 1 is wound on a rotary drum 21 by 221 deg. and the PCM sound signal is recorded on the overlapped part by nearly 28 deg. by means of two rotary recording heads 46, 48 while the signal is subjected to time compression. The recording head 46 records a video signal between times t4 and t8 and the recording head 48 records the PCM sound signal between times t7 and t8. Conversely the recording head 48 records the video signal between times t8 and t12 and the recording head 46 records the PCM sound signal between times t11 and t12. The same erasure current cannot be flowed to the two rotary erasure heads, and a rotary transformer is connected respectively independently to the erasure head and an individual erasure current flows to the erasure heads. Thus, the number of the rotary heads and the number of channels of the rotary transformers are saved by one each.

Title: Method for obtaining slip of autonomous moving unit and method for planning running path
Inventor: RUUDORUFU BAUAA
IPC: G05D1/02
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To find an accumulated slip at a starting point by weighting a preset slip according to Gaussian distribution and selecting the Gaussian distribution to be larger than the maximum value of Gaussian curve. SOLUTION: In order to predict total slip accumulated from a starting point to a coal point, an imaginary motion track of an autonomous moving unit AE is formed by synthesizing three elements, i.e., first rotation of first rotational angle θ1 at the starting point, driving from the starting point to the goal point, and second rotation of second rotational angle θ2 at the goal point. Imaginary traveling section of each wheel is then determined from the dimensions of unit AE in conjunction with three-wheel motion dynamics and motion track. It is multiplied by a preset slip to determine the total slip for each wheel of unit AE. The preset slip is weighted according to Gaussian distribution and the Gaussian distribution is selected to be larger than the maximum value of Gaussian curve.

Title: Crystallizing apparatus
Inventor: KOBAYASHI AKIO
IPC: B01D9/02
Filed: 1979-12-29
Abstract: PURPOSE: To prevent deposited crystals from sticking on the cooling surface of a tank type cooled crystallizing apparatus by making said cooling surface of a flexible synthetic resin tube and giving twisting rotation and vertical movement.  
     CONSTITUTION: Liquid to be crystallized is put into a crystallizing tank 1, and a refrigerant is passed from a flexible pipe 6 into a cooling pipe body 2, and the body 2 is reciprocatively rotated. The reciprocative rotation is accomplished by converting the rotation of a motor 10 with a transducer 11. A rotary shaft 3 is so constituted as to differ in rotation angle with the upper part and lower part, and is given twisting rotation at 90W180° in the upper part and about 1/2 that in the lower part. Further, a horizontal supporting bar 4 fixing both end parts of the cooling pipe body 2 moves vertically along with the rotation and therefore vertical movement is given to the body 2. Crystals cannot stick to the surface of the cooling pipe body, and the deposited crystals settle to the classifying leg 30 in the crystallizing tank bottom, and are taken out as slurry from a crystal take-out port 8. Since no crystals stick to the surface of the cooling pipe body, continuous operation in feasible.

That is, which of one or plural kinds of operating commands of which device the data represents is discriminated based on the preset data. Thus, the generation of plural knds of commands and command control of plural devices are executed easily by simply operating the switch once.

Filed: 1990-06-30
Abstract: PURPOSE:To enhance an integration density and the coefficient of utilization of a basic cell and to manufacture this device by a simple process by forming the basic cell in which a MIS transistor and a bipolar transistor have been formed inside the same well. CONSTITUTION:P-channel MOS transistors Q1, Q2 are formed inside an n-well 2 which has been formed in a semiconductor substrate 1 such as, e.g. a p-type silicon substrate. N-channel MOS transistors Q3, Q4 are formed inside a p-well 3 which is formed in the substrate 1. A symbol 4 indicated a field oxide film such as, e.g. an SiO2 film. A bipolar transistor is not arranged at the outside of a basic cell for a CMOS gate array so as to be adjacent to it; and the bipolar transistor is arranged inside the basic cell. As a result, an integration density can be increased. Even when the coefficient of utilization of the bipolar transistor is low, it does not influence the coefficient of utilization of the basic cell. As a result, the coefficient of utilization of the basic cell can be increased as compared with conventional bipolar CMOS gate arrays. The manufacturing process of this device can be made the same as the conventional one.
