Title: Semiconductor memory device
Inventor: OCHIAI AKIHIKO
IPC: H01L27/04
Filed: 1987-06-05
Abstract: PURPOSE:To improve processability in manufacturing processes after the formation of word lines and to improve the reliability of resulting devices, by burying a charge storing capacitor electrode within a groove instead of extending on the surface of a semiconductor substrate. CONSTITUTION:A polycrystalline silicon layer 16 having phosphorus incorporated therein is formed within a groove 14. The layer 16 is then etched so as to be flush with a silicon semiconductor substrate 1. The first layer formed within the groove 14, namely the polycrystalline silicon layer 16 provides a charge- storing capacitor electrode 18. An SiO2 is then removed and gate oxidation is newly performed so that a gate oxide film 19 and a polycrystalline silicon oxide film 20 are formed. Simultaneously therewith, the dopant is diffused from the polycrystalline silicon layer 16 doped with phosphorus through the region 17 where a capacitor dielectric film 15 is not present, whereby an n<+> diffused layer 21 is formed within the substrate 1. According to this method, the flatness of the surface can be improved and hence processability in the manufacturing processes can be improved. Thus, devices thus formed are allowed to have improved reliability.

Abstract: PURPOSE:To improve the reliability of inadequacy judgment by providing an inadequate heated object detector, and judging the adequacy of a heated object based on the relation between the detected value of the output current of an inverter and the detected value of the phase difference. CONSTITUTION:The output current I0 of an inverter 3 is detected by a current transformer CT and full-wave rectified by a rectifying circuit 7 then smoothed by a filter 8.

The cooling water having an increased temp. is discharged to a draining system for the cooling water and the fresh water produced by condensation is obtd. from a system 17. The efficiency of the heat exchange and evaporation is improved if the flow of the liquid is made to counter current in the chamber 8 and the chamber 9.

Title: Discharge lamp, lighting device and lighting system
Inventor: MITA KAZUTOSHI
IPC: H05B41/24
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device capable of reliably holding a state in abnormality. SOLUTION: When voltage of a fluorescent lamp FL is raised caused by half-wave discharge, voltage of a condenser C7 is also raised, a condenser C8 is charged, a light emitting diode LED1 emits light by turning on a Zener diode ZD2, and a phototransistor Q6 is turned on. The output of an inverter circuit 1 is lowered by bypassing base current of a transformer Q1. Since electric potentials of the connecting points of a resistor R6 and a condenser C11 are high in a state where the inverter circuit 1 is not operated, the condenser C11 is charged through the resistor R6. Holding current is supplied from a DC power supply E and the condenser C11 to the Zener diode ZD2 through a diode D6, a state where the light emitting diode LED 1 emits light is maintained, and the on state of the phototransistor Q6 is maintained.  Therefore, the fluorescent lamp FL is prevented from being flashed on and off caused by the operation of the inverter circuit 1, and stress is not generated on the fluorescent lamp FL.

IPC: H04L12/50
Filed: 1988-06-09
Abstract: PURPOSE:To attain high speed data communication by giving frame delay to plural B channels in a transmission part, inserting a bit string displaying the transmission time of data, receiving the bit string and deciding a delay time difference between plural channels. CONSTITUTION:Since an H0 channel has a band width six times as large as that of the B channels, an H0 band is divided and 64Kb/S signals are respectively set as h1-h6. A time signal generation circuit DB18 inserts signals which show '1' only in one frame into all the signals h1-h6. A terminal equipment on a reception side informs the terminal equipment on a transmission side of a reference channel (h1, for example) and a relative time difference. Thus, the terminal equipment on the transmission side controls a delay buffer circuit DB20, adds the delay of three frames to the signals h1 and h3, two frames to the signals h4 and h6, and one frame to the signal h2, and equalizes the total delay time on respective data on the signals h1-h6. When an insertor I13 is reset to a normal mode after said processing, a link equivalent to the H0 channel can be obtained.
