Abstract: PURPOSE:To make it possible to use the device at high breakdown strength, by providing a gate electrode and a gate oxide film on a substrate, connecting one of source/drain regions formed thereon so as to hold an inverted layer region in-between to an input terminal, connecting the other to a grounding terminal or a power source terminal, and connecting either of them to the gate electrode. CONSTITUTION:An N well, which is used as a gate electrode 7, is formed from the surface to the inside of a P-type semiconductor substrate 8. A gate oxide film 9, source/drain regions 6A and 6B comprising polycrystalline silicon and an inverted layer region 5 are formed on the surface of the N well. Thus a MOS transistor is formed. Then, an external wiring 11 is taken out of a contact region 10 and one end of the source/drain region 6B and connected to an input terminal. An external wiring 12 is taken out of one end of the source/drain region 6A and connected to a grounding terminal. When an excessive voltage is applied, the MOS transistor is turned ON, and the voltage is clipped to a threshold voltage value. When the gate oxide film 9 is formed at an appropriate thickness, the device can be operated with the input having the desired breakdown strength with respect to the input signal.

Title: Fluidic gas shutting apparatus
Inventor: UEKI KOICHI
IPC: G01F1/20
Filed: 1992-10-09
Abstract: PURPOSE:To measure the flow rate of a fluid with a single sensor without being influenced by the temperature of the fluid, by automatically adjusting the width of a jetting nozzle of a fluidic oscillator element to be an optimum value in accordance with the oscillating frequency. CONSTITUTION:The width of a jet flow of a fluidic oscillator element 2 is set at a default value beforehand. When a gas is started to be used, the element 25 oscillates the fluid by the Coanda effect. The oscillating frequency of the fluid is detected at 26. A width controlling means 27 detects whether the oscillating frequency is not smaller than a predetermined value. If the frequency is not smaller than a predetermined value, a width variable means 28 is urged, so that the width of a jetting nozzle of the element 25 is automatically varied. At the same time, the position of the variable means 28 is detected at 27b. When the position becomes a set value, the variable means 28 is stopped to be moved and held at the position. The flow rate is obtained at 29 from the detected oscillating frequency at 26, and an integrated value of the flow rate of the used gas is obtained by an integrated flow rate operating means 30. A judging means 31 judges the using state of the gas from the flow rate and the integrated flow rate. If the using state is abnormal, the judging means 31 activates a shutting means 33, thereby, to stop the supply of gas.

Title: Photo semiconductor device
Inventor: ARIMA YOSHIO
IPC: H01L23/48
Filed: 1984-12-24
Abstract: PURPOSE:To enable sufficient effect of reflection without the use of expensive Ag-soldered layers by a method wherein the reflection surface of a tray reflector on which a light emitting semiconductor element is mounted is made of pure aluminum, aluminum alloy, or aluminum plating. CONSTITUTION:A lead frame 22 provided with the tray reflector 21 on which a light emitting semiconductor element is mounted is made of aluminum. The lead frame has a Cu-plated layer 23 formed over the surface of an aluminum core by excluding the reflector 21. Since no use of expensive Ag is necessary, the effect of cost reduction is very large. Besides, the process of Ag plating and the like are unnecessitated; therefore, the manufacturing process can be simplified. Aluminum alloy can be used for the lead frame instead of a pure aluminum core material; otherwise, the material having iron in the lead frame and plated with aluminum or the like in the reflection surface of said reflector can be used.
