Inventor: KOU SEIGUU
IPC: H01L29/778
Filed: 1994-03-10
Abstract: PURPOSE:To utilize the hysteresis caused by exchange interaction or correlation interaction as a memory and to utilize the total increase of conductivity as a switch by arranging a plurality of quantum dots, where the charged carrier transporting characteristics are determined by exchange interaction or electron interaction, closely each other. CONSTITUTION:In the drawing, a dark part represents a metal gate. A negative bias is applied to the metal gate in order to deplete two-dimensional electron gas under the gate part thus forming a quantum dot. Three gates 43VA, 45VC, 36VD constitute a first quantum dot whereas three gates 43VA, 45VC, 44VB constitute a second quantum dot. Consequently, the source-drain current exhibits definite hysteresis characteristics with respect to the variation of applying voltage and the element itself can be employed as a memory cell. Furthermore, the total increase of conductivity can be utilized as a switch.

Abstract: PURPOSE:To obtain a uniform impurity concentration over the whole of the main face of a semiconductor substrate by installing the following: a means to measure the amount of an electric charge to be electrified on the semiconductor substrate when ions are implanted; a means to suppress electrification on the semiconductor substrate by feeding back a change in the measured amount of the electric charge to an ion implantation apparatus. CONSTITUTION:The following are installed: a means 50 to measure the amount of an electric charge to be electrified on a semiconductor substrate 10 when ions are implanted by using an ion implantation apparatus; a means to suppress electrification on the semiconductor substrate 10 by feeding back a change in the measured amount of the electric charge to the ion implantation apparatus. For example, when the semiconductor substrate 10 is irradiated with a beam current 30, a positive charge passes through a clamper 60 and an end station 20 and is absorbed by a ground; its current is usually constant. When the semiconductor substrate 10 is electrified by the positive charge, its electric current is reduced; a change in a value of the electric current flowing between the clamper 60 and the end station 20 is measured by using a small- current measuring instrument 50; the change is fed back to a beam-current generator 40; the beam current 30 is adjusted in order to suppress electrification by the positive charge.

Abstract: PURPOSE:To make the color reproducibility constant at all times independently of the color arithmetic processing characteristic of a color image forming device by introducing the color gradation pattern formed by a 1st laser beam printer to a 2nd laser beam printer to compare them. CONSTITUTION:The 1st laser beam printer 36A is used to form 64-stage of gradation patterns on a transfer paper sheet 13A and it is read by an optical system unit CCD 7 and its picture signal is introduced to the 2nd laser beam printer 36B and stored in a RAM. Then the gradation pattern formed on the transfer paper 13B is read again by the CCD 7 to be compared with a picture stored already in the RAM. As a result, when it is decided that the densities of both the patterns are not coincident nor close to each other, the optimum conversion coefficient is determined according to the method such as the least square means. Thus, the gradation pattern formed on the transfer paper sheets 13A, 13B is equal (or nearly equal) with each other, the color reproducibilities of the printers 13C as well as 36A, 36B are equal with each other.

Title: Blood pressure monitoring method and apparatus
Inventor: HARADA CHIKAO
IPC: A61B5/022
Filed: 1988-02-23
Abstract: PURPOSE:To sufficiently obtain the measuring accuracy of blood pressure and to alleviate the pain given to a living body by correcting the preliminarily calculated relation between the pulse wave detected by a pulse wave sensor and a blood pressure value on the basis of an actual blood pressure value and a pulse wave simultaneously with the measurement of the actual blood pressure value. CONSTITUTION:A pressure sensor 14 detects the pressure in a cuff 10 to output a cuff pressure signal SP showing the cuff pressure P to a CPU 24. The CPU 24 determines the cuff pressure P as maximal and minimal blood pressures on the basis of a pulse sound signal SO and the cuff pressure signal SP. A pulse wave sensor 32 detects a pulse wave from the radial artery to supply a pulse wave signal SM showing said pulse wave to the CPU 24 through an A/D converter 34. On the basis of the pulse wave detected when a blood pressure value is determined, the corresponding relation between the blood pressure value and the pulse wave is corrected at each time when an actual blood pressure value is detected. Therefore, the corresponding relation between the blood pressure value and the pulse wave is always accurately obtained and the measuring accuracy of blood pressure is sufficiently obtained. Since a blood pressure value is monitored only by pressing a part of a living body at a definite time interval, the pain given to the living body is alleviated to a large extent.

Filed: 1986-02-26
Abstract: PURPOSE:To make automation for storage adjustment of articles during conveyance attainable, by making a transfer adjusting conveyor so as to travel in a direction to be crossed with both carry-in and carry-out conveyors according to their speed differences and to increase or decrease a storage of these articles according to this travel. CONSTITUTION:When trouble happens in a manufacturing machine at the latter stage and a carry-out conveyor 2 is suspended, if a controlling sprocket 24 is stopped, a transfer adjusting conveyor 3 is made to go up as in an arrow D as a whole, whereby a lifting speed becomes halved in an A direction. Next, if the conveyor 3 goes up, a transfer distance in the conveyor 3 ranging from a carry-in conveyor 1 to 2 is increased, storing articles 4, and if a storage in case of reaching a top dead center comes to fullness, the conveyor 1 stops. Reversely, when trouble happens in the manufacturing machine at the preceding stage and the conveyor 1 is stopped, the conveyor 3 goes down and transfers the article 4 onto the conveyor 2 so that storage length on the conveyor 3 becomes shorter, reducing the storage, and when the storage runs short as reached to a bottom dead center, the sprocket 24 is stopped. Therefore, travel adjustment is automatically performable.
