Title: Constitution of neuron and neural network
Inventor: TANAKA MAMORU
IPC: H01L27/092
Filed: 1994-03-23
Abstract: PURPOSE:To give integration an advantage and to prevent local minimum in an associative operation from generating by connecting the outputs of plural CMOS inverter circuits in common and generating the result of a product -sum operation weighted for the input of each circuit at a common node. CONSTITUTION:The CMOS circuits composed of the series connection of P-MOS transistors and C-MOS transistors are connected in cascade, each of the outputs of the P-MOS and C-MOS are connected in common, it is defined as common node and it is connected with the input of one of comparators. The other input of the comparator is the analog input of a threshold. By using a fact that the voltage Vout of the common node of the P-MOS and an N-MOS is determined so that the current flowing in the P-MOS and the current flowing in the N-MOS may be equal, a product -sum operation is formed. An equivalent conductance is proportional to the ratio of W/L of the width and length of a channel, drain current can be changed by the process control of the mask and learning becomes possible.

IPC: F04B49/08
Filed: 1984-03-21
Abstract: PURPOSE:To obtain an inlet control device having a less energy loss, by making the discharge pressure of the inlet control device affect upon a control member with the use of a change-over valve when the discharge pressure is below a set pressure. CONSTITUTION:Two hydraulic pumps 3a, 3b are driven by a single motor 1. Change-over valves 12a, 12b are disposed between pressure reducing valves 11b, 11a in a control circuit and control members 4a, 4b in cylinder chambers 10a, 10b. The set pressures of these change-over valves 12a, 12b are slightly lower than the set pressures of relief valves 30a, 30b. Either one of the change-over valves 12a, 12b make the discharge pressure of a pump 3b belonging to the other change-over valve affect upon the cylinder chamber 10a when the discharge pressure of a pump 3a belonging to itself is below a set value. In this case the control is made as usual. When the discharge pressure exceeds a set value, the change-over valve 12a make the discharge pressure of the pump 3a belonging itself affect upon the cylinder chamber 10a to reduce its discharge flow. The same steps are taken for another pump 3b.

Filed: 1987-03-10
Abstract: PURPOSE:To simplify a production process and to achieve the high yield rate by a method wherein a low part on both sides of a mesa-shaped active region is buried with a heat-resisting and high-resistance resin whose coefficient of thermal expansion is very close to that of the active region. CONSTITUTION:A heat-resisting and high-resistance resin is placed at a low part on both sides of a mesa part in such a way that its height is almost equal to the surface of the mesa part; an electrode is formed on the surface of the mesa part and on the surface of the heat-resisting and high-resistance resin. This heat-resisting and high-resistance resin is transformed into a low-thermal- expansion resin whose coefficient of thermal expansion is almost the same as that of a semiconductor material constituting a semiconductor laser. Accrodinglly, the crystal growth can be executed by only one crystal growth process of a double heterojunction. By this setup, a production process is simplified; in addition, because the coefficient of thermal expansion of the heat- resisting and high-resistance resin is close to that of the semiconductor, the breakdown strength of the junction at an active region is not deteriorated, it is possible to achieve the high yield rate.

Filed: 1994-02-26
Abstract: PURPOSE:To improve the accuracy in ventilation control by a method wherein when air pollutant concentration in a tunnel is within a set range including desired concentration, a fan is driven and controlled by a program control method and when the concentration is out of the set range, the fan is controlled by a feedback control method. CONSTITUTION:When ventilation is controlled by a program controller 11, pollutant concentration V1 in a tunnel is within a set range and hence a change- over switch 12 is changed over to the side of the controller 11 so that number of jet fans set by the controller 11 are driven to effect tunnel ventilation. During this control, if actual volume of traffic varies, deviating from a set pattern, and the pollutant concentration at a predetermined time falls below a lower limit value, the pollutant concentration is sensed by a monitoring element 22 so that the switch 12 is changed over to the side of a converter 21 to start a feedback control, following which a CPU unit outputs converted number of fans to a control unit 13. When the pollutant concentration returns to the lower limit value of the set range at a predetermined time, the switch 12 is changed over to the side of the controller 11.

SOLUTION: The selection period of a certain pixel is time-divided into P pieces (P is a positive integer >=2) and when respective periods are defined as T(1)∼T(P) in the order of time, a column voltage corresponding from T(1) to T(P) is an on-level and a column voltage corresponding from to T(1) to T(P) is an off-level and then the number of changing times of the on-level and the off-level in the selection period is made to be zero or one time. When the phase of a column waveform is made so as to be inverted into a positive phase and a negative phase every one selection period as shown in the (b) column of the Figure in such a way, the number of changing of a voltage is reduced as compared with that in the case of a column waveform shown in the column (a) of the Figure and also the pulse width is increased.
