Abstract: PURPOSE:To enable etching process of a silicon nitriding film to be efficient and stable and uniformity of characteristics of a semiconductor device and production yield to be improved by controlling temperature and concentration of phosphoric acid solution in reference to a specific boiling point. CONSTITUTION:A phosphoric acid aqueous solution 1 at a specific concentration is heated to a boiling point at its concentration by a heater 3 within a treatment tank 2. A control device 6 instructs supply of a low-concentration phosphoric acid solution for a phosphoric acid solution supply device 4 after a specified time from detection that temperature of the phosphoric aqueous solution 1 exceeds the boiling point by a temperature sensor 5. Also, when it is detected that the temperature of the phosphoric acid aqueous solution 1 is reduced from the boiling point by a specified value, stopping supply of the low-concentration phosphoric acid is instructed. Therefore, since silicon nitriding film is etched by phosphoric aqueous solution whose concentration and temperature are controlled, efficiency of the etching process is improved and excessive etching is prevented, thus enabling uniformity of products and production yield to be improved.

Title: Damping device of steel skeleton structure
Inventor: MIZUHASHI SUSUMU
IPC: F16F15/023
Filed: 1994-09-30
Abstract: PURPOSE: To absorb vibration of a structure, by generating an attenuation force when a hydraulic liquid flows in an orifice passage, by the extension and contraction of inner and outer bellows cylinders. CONSTITUTION: When a tensile force works, an outer bellows cylinder 14 is uniformly extended but the elongation of an inner bellows cylinder 16 are different in the air chamber 19 and the inside liquid chamber 20. The air chamber is actuated to extend longer and the inside liquid chamber is actuated to contract shorter. And the outside air is sucked into the air chamber 19 through a suction and exhaust pass 18 in accordance with the volume increase as a whole. And the hydraulic fluid is transferred from the inside liquid chamber 20 to the outside liquid chamber 21 in accordance with the volumetric change of the liquid chambers 20, 21. In this time, a damping device 6 generates an attenuation force owing to the passing resistance on passing the inside and outside orifice holes 23, 24.  When a compressive force works, the outer bellows cylinder 14 is contracted evenly and the air in the chamber is discharged from the air chamber 19 and the hydraulic liquid S is transferred from the outside liquid chamber 21 to the inside liquid chamber 20 and an attenuation force is brought likewise due to the generated passing resistance.

Abstract: PURPOSE:To realize excellent inter-circuit isolation by providing an insulator wall having a conductor connecting to ground in terms of high frequencies to its inside or on its outer surface between a specific circuit comprising plural circuit components and other circuit having interconnecting lines connecting the said specific circuit and the said other circuit inbetween. CONSTITUTION:A via hole 3 provided in the inside of each insulator 5 is connected to a conductor layer 6 provided to inter-layer of each insulator 5 and connected to the conductor layer 6 being a ground electrode at a lowermost layer. Since the interval of the via holes 3 is selected shorter than a wavelength A with respect to an operating frequency (f) of circuits A1, B2, the microwave whose frequency is (f) cannot transmit through the wall as well known. Thus, the wall acts as a ground wall in terms of the microwave and it is possible to reduce undesired leakage of the microwave having been caused between the circuits A1 and B2 thereby realizing excellent isolation. The via holes 3 of upper and lower layers are placed at different locations because the effect of roughness of each via hole 3 due to metallizing is not given to the via holes 3 of the upper and lower layers.

Title: Battery discharge prevention apparatus
Inventor: NAGAI TAKASHI
IPC: H02J7/10
Filed: 1988-09-22
Abstract: PURPOSE:To perform a stable charge with little variation relative to a set voltage by providing a temperature correction circuit operating to bring a charge completed voltage close to a specified completed voltage between a current control circuit and a voltage sensing circuit. CONSTITUTION:A correction circuit 9 for temperature varying with an ambient temperature is inserted between a current control circuit 5 and a current sensing circuit 7. In said temperature correction circuit 9, a positive temperature coefficient thermistor RTH rising in its resistance value with the rise of said ambient temperature is inserted between and connected in series with resistor r1, r2. Unless a voltage V1 rises with the temperature rise, VBE becomes smaller consequently, and the terminal voltage V of a battery 6 becomes somewhat larger, a transistor TR2 foes not become completely ON. Relative to a charge completed voltage, in this manner, such inconvenience as the completion of charge at low voltage does not occur even if the temperature rises, unlike an apparatus known heretofore.
