Title: Non-volatile semiconductor memory device
Inventor: HASHIMOTO KIYOKAZU
IPC: G11C17/00
Filed: 1988-02-24
Abstract: PURPOSE:To operate a comparison detector according to a designed value by setting the output voltage of a reference voltage generating circuit to the intermediate of the output voltage of a sense amplifying circuit when a pseudo memory element is written, the threshold thereof is changed and the memory element storing 0 and 1 is selected. CONSTITUTION:In the reference voltage generating circuit, the pseudo memory element (reference cell) M3 which is the same in a structure and a characteristic as a storing cell is disposed and the reference cell M3 is written by a similar means to the storing cell to control a current changing a the threshold and flowing and set to the intermediate of the output voltage of the sense amplifying circuit when the storing cell where the output is written and an erased storing cell are selected. Accordingly, the current voltage characteristics of the storing cell and the reference cell M3 have the characteristics having no saturation area and even when the output voltage of the sense amplifying circuit is changed due to the change of the threshold and the fluctuation in a process condition, the output voltage of the reference voltage generating circuit is similarly changed. Thereby, the difference between both output voltages is substantially equal to the designed value to prevent difficulty in a detection by the comparison detector of a next step.

Title: Semiconductor light emitting device
Inventor: JIYOUSA YASUO
IPC: H01L21/52
Filed: 1984-03-06
Abstract: PURPOSE:To prevent a photoconductive adhesion layer from creeping on the surface of light emitting elements by a method wherein creep preventing parts of conductive layer are provided either one of the light emitting element arraying parts of a printed substrate or both of an opposing surface of the light emitting elements to the printed surface. CONSTITUTION:Multiple grooves 24 are provided on the bottom of element arraying groove 23 of a printed substrate 21.

Title: Manufacture of junction type field effect transistor
Inventor: MISAWA HIROSHI
IPC: H01L29/80
Filed: 1981-03-24
Abstract: PURPOSE:To obtain an FET having small gate capacity without decreasing a mutual conductance by forming a region having lower density of impurity than a channel part at the periphery of a gate forming a J-FET. CONSTITUTION:The first conductive type region 1 is formed in the second conductive type semiconductor substrate 2, an SiO2 film 5 is covered on the overall surface including the first region 1, and impurity ions are injected from the surface to form source and drain regions 3 of the second conductive type in the region 1. At this time the density of the impurity in the region 3 is increased by 5-6 places higher than that of the region 1, and the resistance value of the region 3 is lowered. Then, the second conductive type region 7 having 1-2 orders of magnitude lower density than the region 1 is diffused and formed between the regions 3 in the region 1 without contact with the regions 3, and a gate region 4 having impurity density 4-5 places higher than the region 1 and a channel region 6 is diffused and formed in the region 7. In this manner, since the capacity of the gate is reduced without decreasing the density of the region 6, the mutual conductance is not lowered.

Title: Automatic transmission
Inventor: IDOGUCHI MASARU
IPC: B60W10/10
Filed: 1986-02-28
Abstract: PURPOSE:To prevent a vehicle from inadvertently rushing out, by providing such an arrangement that an accelerator pedal is depressed in a condition in which the pressure of air fed into an actuator is lower than an operating pressure, and the vehicle is inhibited from starting in this condition even if the pressure of air increases up to the operating operation. CONSTITUTION:When an automatic transmission 15 starts a vehicle, a microcomputer 21 reads at first the shift position of the transmission, and then reads the pressure in the air tank 33 by means of a pressure sensor 37 when the shift position is other than the neutral position. When the pressure in the air tank 33 is less than an operating pressure, a compressor 31 is driven by an engine 10 to accumulate air in the tank 33. Then, the microcomputer 21 detects the degree of depression of the accelerator pedal 24 by means of an accelerator sensor 25. When an accelerator pedal 24 is depressed again after it is once returned, solenoid valves 34 through 36 are opened to feed air into actuators 17 through 19 to carry out shift operation and engagement of the clutch.

Title: Gas blast breaker device
Inventor: NAKANE SHINICHI
IPC: A62C2/04
Filed: 1990-02-23
Abstract: PURPOSE:To have proper setting of gas blast breaking level at all times by changing over from the auto-setting mode to the fixed setting mode in which the proper service conditions are set only from signals given by an initial condition memory part, or vice versa, and thereby actuating the fixed setting function in case the auto-setting function is in failure for a gas user who uses special gas. CONSTITUTION:In the fixed setting mode, the service conditions stored in an initial conditions memory part 3 are used as the reference level for comparison at a proper service condition judging part, and the current gas using condition is judged. In the auto-setting mode, the proper service conditions are set automatically from the data retained in a service condition memory and computing part during period with a timer performing clocking, that provides an effective means to the setting work reasonable for most gas-meter installed users. Because an auto/fixed changeover part 12 is provided, the auto-setting mode becomes improper for any user who uses special gas, and for him, setting of specified service conditions is available by changing over into the fixed setting mode if breaking may occur even in the condition normal gas is used.

Abstract: PURPOSE:To make it possible to inspect a heat sensor by remote control by providing the heat sensor with an inspection circuit for inputting a dummy sensing input to a decision part similarly to the detection of a fire by a heat sensing element at the time of inputting an inspection signal. CONSTITUTION:An inspection signal line T for sending an inspection signal from the side of a fire receiver is previously wired, and the inspection circuit 2 for boosting a voltage impressed to both terminals of a resistor R1 up to the level to be obtained at the time of generating a fire and forming a dummy fire state is arranged in the heat sensor.

Consequently, the heat sensor can be inspected by remote operation for inputting the inspection signal from the signal line T, so that the heat sensor can be detected without going to its installation field.

Abstract: PURPOSE:To make the circuit scale small by inputting a pulse position by an address in a frame, and using in common a maximum value detecting part, a minimum value detecting part and an arithmetic part, even when plural pieces of groups containing a terminal group exists. CONSTITUTION:Pulses from terminals A-D are stored as addresses in a frame in address memories 2-5, respectively, and the maximum value and the minimum value of these addresses are detected by a maximum value detecting part 6 and a minimum value detecting part 7, respectively. Subsequently, in an arithmetic part 8, an operation is executed, based on data from the maximum value detecting part 6 and the minimum value detecting part 7, and (the maximum value - the minimum value)/2 is calculated. On the other hand, an output of the arithmetic part 8 and an output of an address counter 1 are inputted to an EOR gate 9. Accordingly, at the time point when an output of an address counter of the next frame coincides with an output of the processing arithmetic part 8, a pulse of a LOW level is outputted. In such a way, even at the time of deriving, for instance, the center phase of plural groups, the circuit scale does not become large.
