Title: Semiconductor device
Inventor: MARUO YUTAKA
IPC: H01L21/8247
Filed: 1988-05-11
Abstract: PURPOSE:To prevent charges stored at a floating gate at the time of reading from leaking by designating a first selected transistor source as a memory transistor drain, and connecting a second selected transistor source to a charging region of the memory transistor. CONSTITUTION:A source 6 and a gate 4 of a first selected transistor are isolated from a source 7 and a gate 2 of a second selected transistor. Drains 1 of both transistors are connected to each other; the source 6 becomes the drain 6 of a memory transistor, and the source 7 is connected to a charging region 8 of the memory transistor. Accordingly, the drain 6 is completely electrically isolated from the charging region 8 of the memory transistor. Thus, even if a voltage for reading is applied between a control gate 9 and the drain 6, a voltage applied to a heavily doped impurity diffusion layer of the charging region 8 can be given arbitrarily, thereby reducing an electric field between a floating gate where charges are stored and another electrode at the time of reading data and thus preventing the charges from leaking.

Title: Constant current circuit
Inventor: ARIMURA MASAHIKO
IPC: G05F3/26
Filed: 1985-05-29
Abstract: PURPOSE:To stabilize a current against the fluctuation of a supply voltage by connecting the emitter of a transistor TR, whose base a reference voltage generating diode is connected to a low potential-side power source and a high potential-side power source through the first and second resistances. CONSTITUTION:The reference voltage generated by diodes D1 and D2 connected between the high potential-side power source (earthed power source) and a low potential-side power source VEE is applied to the base of a TR Q1. The emitter of the TR Q1 is connected to not only the low potential-side power source VEE through the first resistance R1 but also the high potential-side power source through the second resistance R4. Since a ratio of the fluctuation of the forward voltage to that of the supply voltage is determined by a ratio of the resistance R4 to the resistance R1, a current I3 flowed to the TR Q1 is constant independently of the fluctuation of the supply voltage VEE.

Abstract: PURPOSE:To make it possible to meet a request to separate only a part of a slave station at the time of repairing trouble etc. by making exchange of on/off information only with a slave station that corresponds to a memory position only with a slave station that corresponds to a memory position in which separation designation information is not written from a sequence control ler. CONSTITUTION:The device is provided with a discriminating means C that discriminates whether on/off information is to be transmitted or not for each of transmitting device of plural slave stations side depending on whether each of plural control signal memory positions in a signal memory A is in the signal state indicating separation. When one of plural control signal memory position in the signal memory A is changed to the signal state that indicate separation, the discriminating means C discriminates that a slave station corresponding to a control signal memory position for which the signal state is changed is the slave station designated to separate. Responding to this, a transmission control means D makes exchange of on off information only with slave stations for which separation is not designated.

Abstract: PURPOSE:To turn lights on and off in accordance with the brightness and darkness regardless of day or night by setting the lighting timing in two steps to turn on immediately when entering into a tunnel in the daytime and again turn on in the twilight time. CONSTITUTION:When entering in a tunnel, collector current of a transister Q8 is increased by a resistor 3 to close a relay RL3, and then relays RL1 and RL2 are successively closed to switch on lights SL and HL in that turn. After getting out of the tunnel, the resistances of the resistors 1 & 2 are lowered and relays RL1 and RL2 are opened to turn off the lights. Meanwhile, in the twilight time, the resistance of the resistor 1 is increased to close the relay RL1, and the light SL is lit. When it becomes darker, the relay RL2 is closed to switch on the light HL as well. Then, when an ignition switch SW1 is off, the power supply is cut off to turn off the lights SL and HL together.
