Title: Acid rain gauge
Inventor: SHIMAZU TETSUTARO
IPC: G01N27/00
Filed: 1989-12-20
Abstract: PURPOSE:To prevent a rainfall start signal from being misdetected owing to dew condensation and to enable highly accurate detection by rotating a lid body in response to the rainfall detection signal of a rain sensor provided with a rain drop sensing part and a dew condensation sensing part. CONSTITUTION:The rain sensor E arranged on the back surface of a lid body opening/ closing driving part 12 on an equipment installation rack 19 is equipped with the rain drop sensing part B and dew condensation sensing part D and senses a rainfall or dew condensation from the short-circuiting of a conductor pattern due to the rainfall or dew condensation. The sensing part B for preventing the dew condensation and rainfall from being misdetected is arranged at the top of a housing 5 and the sensing part D is arranged in the housing 5. Then the lid body 15 is fitted on a rainfall collec tor 14 unless it rains, and when it begins to rain, the driving part 12 rotates an arm 18 in a direction from (a) to (b) with the rainfall detection signal of the sensor E, thereby fitting the lid body 15 even on a fall dirt collector 13. If temperature rises at high humidity to cause dew condensation at the sensing part B, the sensing part D detects the dew condensation at the same time, so the generation of a wrong signal can be evaded and the lid body 15 is accurately rotated only at the time of the fainfall.

Title: Switching power supply
Inventor: NAGAHARA KIYOKAZU
IPC: H02M3/28
Filed: 1994-12-07
Abstract: PURPOSE: To eliminate the need of current detection resistor in an overcurrent detection circuit by determining an abnormal operation based on a detection signal from a constant voltage control system. CONSTITUTION: When a load RL enters into a low impedance state similar to short circuit state to cause increase of output current, power can not be fed sufficiently from the output transformer of a power supply circuit and thereby DC output voltage E0 drops. Consequently, the divided DC voltage in a voltage detection circuit 2 drops to bring a shunt regulator SR into nonconducting state thus cutting off the phototransistor PT in a photocoupler PC. As a result, potential of a capacitor C5 increases and the comparison potential V3 of an error amplifier A1 is substantially equalized to the potential of a reference power supply ER thus producing an inverted detection signal from an error amplifier A1 . Since oscillation of a control circuit 1 is interrupted, the switching operation is stopped and an overcurrent protective circuit is actuated.

Title: Converter
Inventor: TAJIMA OSAMU
IPC: H01M8/06
Filed: 1994-12-09
Abstract: PURPOSE: To provide a converter placed along the outer periphery of a reformer and capable of reducing a CO-concentration to a low level. CONSTITUTION: This converter 4 is heated by the heat from the reformer through a heat insulating material and cooled by cooling coils 52 and 53 during operation. The temperature distribution throughout from the inlet to the outlet of the converter 4 is controlled by controlling the cooling power of the cooling coils 52 and 53. In a thin region 51a where the width of a catalyst layer is narrow, the cooling coil 52 is placed on the outer periphery of the container and the cooling coil 53 is placed on the inner periphery. Since the width in the thin region 51a is narrower than that of a thick region 51b, a temperature difference between outer side and inner side is small in the thin region 51a. Accordingly, the temperature control is easy in this region, and a desirable temperature distribution can be formed throughout from the inlet to the outlet.

Title: Analyzing method for glow discharge light emission
Inventor: MIYAMA TAKAO
IPC: G01N21/67
Filed: 1992-09-30
Abstract: PURPOSE:To analyze in a depth direction with high S/N and high accuracy in a short time by integrating a light emitting intensity of a glow discharge by a standard sample having uniform composition, and forming a calibration curve by predetermined integrat ing time with a plurality of standard samples. CONSTITUTION:A light emitting intensity of a glow discharge is integrated by using one standard sample having uniform composition, and relationship between a light quantity integrated value and a time is actually measured. A calibration curve is formed by predetermined integrating time with a plurality of standard samples having uniform composition. A real sample is measured by using a shorter integrating time than that at the time of forming the curve, a light quantity integrated value of each depth is converted to a light quantity integrated value with respect to the integrating time at the time of forming the curve in terms of the relationship between the light quantity integrated value by the actual measurement and the integrating time, and the curve is applied. Since a time of the light quantity integration in the analysis of the real sample short but a time of the light quantity integration for forming the curve is provided for a sufficiently long period, an S/N ratio of an analysis result is determined only by the S/N of the light quantity integrated value of the real sample, thereby improving the S/N ratio.
