IPC: G01N25/00
Filed: 1985-01-30
Abstract: PURPOSE:To check for the generation of lameller separation accurately, by statistically processing the temperatures detected at respective measuring points. CONSTITUTION:K pieces of temperature sensors 11-1k are provided on a liquified natural gas LNG tank 8 and connected in series thereto. When current is fed from a constant current source 2, resistance values of the sensors vary with the temperature at the corresponding point to the LNG, causing a change in the terminal voltages thereof. The terminal voltages thereof are taken into a data processor 7 to be memorized 6 through a multiplexer 3 and an A/D converter 4. It is assumed that a lameller separation of the LNG is caused using measured values of the sensors housed in an equipment 6. The temperature measured values are divided into two groups, upper and lower layers and the goodness-fit when the group-wise distribution of the temperature measured values are found to follow the normal distribution and the goodness-fit when the distribution of the temperature measured values over all measuring points are compared using the reference value of AIC information reference level as evaluation function of the adaptability. Based on the results of the comparison, the presence of the LNG lameller separation is detected.

Title: Semiconductor light emitting element
Inventor: IDEI YASUO
IPC: H01L33/30
Filed: 1988-01-27
Abstract: PURPOSE:To improve the yield rate of a wafer process, in a semiconductor light emitting element having a double hetero-structure, by laminating a GaAlAs buffer layer having the same conductivity type whose mixed crystal ratio of AlAs and thickness are within the specified ranges on the surface of a one-conductivity type GaAs substrate, and laminating one-conductivity type GaAlAs layer whose mixed crystal ratio of AlAs is 0.5 or more on the surface of said buffer layer. CONSTITUTION:In a semiconductor light emitting element having a double hetero-structure, lattice misalignment is largely yielded between a one-conductivity type GaAs substrate 1 and a same-conductivity type GaAlAs clad layer 3 that is laminated on the surface of the substrate 1. When a one-conductivity type GaAlAs buffer layer 3 whose mixed crystal ratio of AlAs is 0.2-0.5 is provided between both layers, lattice strain is alleviated. Namely, the mixed crystal ratio of AlAs is changed from 0 (1) to 0.2-0.5 (2) and further to 0.7 (3) from the side of the GaAs substrate 1. Thus, the lattice strain is alleviated. When the mixed crystal ratio of AlAs exceeds 0.2-0.5 in the GaAlAs buffer layer, the strain is not alleviated. When the thickness of the buffer layer exceeds 5-50mum, the warping amount of the substrate is increased, and a lot of troubles occur in the manufacturing process of the light emitting element.

Title: No battery capacity notifying circuit for alarm device
Inventor: KATAZUKI KUNIHARU
IPC: G08B21/00
Filed: 1979-02-09
Abstract: PURPOSE: To reduce the required materials for an alarming device by commonly using one oscillator of an ultralong period oscillator for driving an alarm unit.  
     CONSTITUTION: The outputs of one oscillator 3 of an ultralong period oscillator 6 and of output holding circuit 11 of a voltage detector 10 are connected to switching elements 14 and 15 connected in series with an alarm unit 13 to thus drive the alarm unit 13. When the output of an AND gate 4 receiving the outputs of the oscillators 2 and 3 is applied to a switching element 9 to conduct the element 9 to thus connect an alarm unit equivalent resistor 8 to a battery 7, a voltage detector 10 detects the voltage change caused thereby. When the battery voltage is lower than predetermined level, the output from the detector 10 is held by a holding circuit 11 to conduct the switching element 14. Accordingly, the alarm unit 13 is driven in response to the conduction of the switching element 15 operated by the output of the oscillator 3. Thus, since the one oscillator 3 of the ultralong period oscillator 6 can be commonly used, it can reduce the required components.
