Title: Bonding and shaping of magnet
Inventor: INOUE KIYOSHI
IPC: H01F7/02
Filed: 1980-12-25
Abstract: PURPOSE:To produce a magnet of a desired shape by a method wherein small columnar magnets with a fixed crosssection or granulated magnets are bound within a fixed area to form an integral magnet package and, into their gaps, magnets or small magnetic particles are diffused and a bonding agent is filled. CONSTITUTION:Small cylindrical magnets 2 with an almost circular crosssection, small magnets 4 and 14 with different diameters but the same shape as magnets 2, and small magnets 3 with a quadrangular pyramid shape of an almost rectangular corsssection are fastened tight with a tightening steel belt 6 to form a hexahedron magnet 1. Next, a bonding agent 7 including magnetic particles is filled into spaces constituted by these magnets 2, 3, 4 and 14 to fix every magnet. This bonding aent 7 is produced by mixing small magnetic particle or grains with rubber and plastics and also mixing fibre chips to enhance a bonding strength. With this process, a magnet of any desired shape can be formed, and furthermore deformation to another shape can be implanted, if needed, after disassembling.

Title: Differential amplifier circuit
Inventor: TAKAGI MASATO
IPC: H03F3/45
Filed: 1988-07-22
Abstract: PURPOSE:To obtain a differential amplifier circuit with excellent linearity and low distortion factor by making output currents of transistors(TRs) equal to each other by means of a current mirror circuit so as to cancel the nonlinear characteristic between differential input terminals. CONSTITUTION:Voltages V'1, V'2 at sources of FETs Q3, Q4 are expressed in equations I, II, where V1, V2 are voltages given from differential input terminals 1, 2 respectively and VGS3, VGS4 are gate-source voltages of the FETs Q3, Q4. Let V1-V2 be Vin, then a current  i is given by equation III. The source current of the FETs Q2, Q3, Q4 is equal independently of the amplitude of the current  i by the operation of current mirror circuits 3, 4. Thus, the change in the gate-source voltages VGS1, VGS2, VGS3, VGS4 due to a change in the current  i is cancelled. That is, the relation of current i=Vin/RG exists. An output voltage V0 of a current voltage conversion circuit 13 is expressed in equation IV. Thus, the nonlinear characteristic such as nonlinearity or distortion is improved.

In the next step, an induction plate 9 is rotated to reach the upper part of a washing container while moving bodies 32, 33 are rotated to reach the position opposed to a non-filtering fluid flowing member 23'. In this case, similar operation is performed but, because the fluid flowing member 23' has no filter arranged therein, a washing liquid is not filtered.

Title: Microscope
Inventor: SUZUKI AKITOSHI
IPC: G02B21/06
Filed: 1986-08-04
Abstract: PURPOSE:To prevent an illuminating luminous flux from being made incident on observer's eyes even in case of switching of an objective lens by outputting a control signal, which stops down an electric field diaphragm member, to the electric field diaphragm member to fully stop down the electric field diaphragm member until a control means intercepts a dark field illuminating luminous flux. CONSTITUTION:When an objective lens switching signal is inputted from a keyboard, the control signal which stops down a field diaphragm member 4a is outputted to the first motor 4c of an electric field stop member 4 to wait for stop-down of the field diaphragm member 4a. The control signal which switches an objective lens 13 is outputted to the second motor 12b of an electric revolver 12. The control signal which fully opens the field diaphragm member 4a of the electric field diaphragm member 4 is outputted to the first motor 4c, and thereafter, the operation is restarted. Thus, the illuminating luminous flux is not made incident on observer's eyes even if the objective lens is switched.

Title: Shift overflow control circuit
Inventor: KAMOI HIDEKI
IPC: G06F7/46
Filed: 1990-07-13
Abstract: PURPOSE:To accurately minimize the data error due to shift overflow by comparing the extent of normalizing shift and the extent of direct instruction shift with each other to set the overflow value to a preliminarily set positive or negative value. CONSTITUTION:When code extended 32-bit operation output D10 is supplied to a shift circuit 11 and a normalizing shift control circuit 12, the circuit 12 detects, for example, 3 extended code bits and outputs a normalizing shift extent S12 corresponding to these bits and gives it to a comparator 13 and a shift instruction selector 14. The normalizing shift extent S12 and a direct instruction shift extent Sb are always compared with each other by the comparator 13, and overflow is detected to give an overflow signal S13 to a data selector 15. The selector 15 outputs a positive maximum value +M or a negative maximum value -M instead of the output of the circuit 11 as output data D20. Consequently, data error is minimized.

Title: Method for processing asynchronous data input and output and program recording medium
Inventor: OGAWA HISASHI
IPC: G06F15/17
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To efficiently input/output data by preventing threads for executing a data area fixing processing from occupying a CPU time for a long time in an asynchronous data input/output processing. SOLUTION: The threads for processing an input/output processing request from a user space process are separated into the first threads (T0, T1,...) and the second ones (A0, A1,...). In the first threads, when a data input/output processing is requested from the user space process, a data area Dn is secured, the second threads are called and the processing is interrupted in order to secure the CPU time by the other threads. In the second threads, a series of processings for inputting/outputting asynchronous data are completed, the condition variable of a kernel system is utilized after that and a state variable is introduced to write a proper value. Then the first threads confirm that the variables become the proper values and continuously execute the interrupted processing.

Filed: 1990-07-12
Abstract: PURPOSE:To transmit detailed information of the center of a picture to be transmitted by quantizing the signal of a concerned area set by a user in quantization steps finer than those for the signal of the other area. CONSTITUTION:Several kinds of pattern are preliminarily prepared in a pattern selecting part 8 for the purpose of setting the concerned area as the important part of a picture to be transmitted. When the user sets the concerned area by the pattern selecting part 8 based on the shot to which the picture to be transmitted conforms, it is discriminated by an area discriminating part 9 whether the signal of each block outputted from an input part 1 corresponds to the concerned area or not, and the signal is quantized in finer quantization steps in a quantizing part 4 by the control of a quantization step control part 5 in the case of the block corresponding to the concerned area. Thus, the concerned area of the picture to be transmitted is transmitted as more distinct picture.

Title: Telescopic top with step
Inventor: ARAI YOICHIRO
IPC: B29L15/00
Filed: 1988-07-26
Abstract: PURPOSE:To avoid burrs from generating at a telescopic top due to its step by forming a small step and a corner groove at the top of a product side, and forming a finely curved face or a taper between the slide face of the top in contact with the inner periphery of a sleeve for slidably moving the top and the groove. CONSTITUTION:A telescopic top 4 is slid under the guidance of the bore of a sleeve 1. In this case, since the sidewall 5 of the upper face of the top for forming a product 3 is smaller in shape than a slide face 6, it slides without contact with the bore of the sleeve 1. The sidewall 5 is integrated with the slide face 6 through a corner groove 2, finely rounded parts R are formed at the edges of the face 6 and the groove 2 to prevent the edge from dragging the sleeve 1 at the time of sliding. Accordingly, the burrs of a molded piece can be minimized.
