Title: Mos transistor and its manufacture
Inventor: ASAKURA FUJIO
IPC: H01L29/78
Filed: 1989-04-07
Abstract: PURPOSE:To relax a field strength in the surface, in which a gate-drain overlap part is located, of a substrate and to inhibit a leakage current in a drain and the deterioration of device characteristics due to hot carriers by a method wherein a protrusion-shaped impurity region is provided in the interior, in which the end of the drain in a channel region is located, of the substrate. CONSTITUTION:The width of a depletion layer 12, which spreads between a drain and a p-type silicon substrate 1, is assumed to be L1 and the width of a depletion layer 12, which spreads in the longitudinal direction in a channel part under a gate, is assumed to be L2 in a state that a MOS transistor does not conduct, that is, on the condition of a gate voltage, in which an inversion layer is not formed in the channel part, and at the time of the condition of a drain voltage, in which an interband tunnelling leakage current is generated in a gate- drain overlap part and has the minimum absolute value. At this time, the surface, which is positioned on the side of the substrate surface, of a junction 11 is connected to a drain region of a conductivity type identical with that of the drain at a distance of L0 from the substrate surface and a protrusion-shaped impurity region 6 is provided in the interior, in which the end of the drain in a channel region is positioned, of the substrate. The L0 is set on the condition of 0<L0<L1+L2. Thereby, the tunnelling leakage current is not substantially generated and in its turn the generation of hot carriers is reduced and the deterioration of device characteristics is inhibited.

Title: Echo detector
Inventor: KOBAYASHI KENICHI
IPC: G01S7/529
Filed: 1984-05-01
Abstract: PURPOSE:To enable the thorough detection of reflected waves from inside the bottom of water by keeping the gain of a receiving amplifier suppressed between the transmission of a wave pulse and the proximity of tye reception of the reflected wave from the wave propagation characteristic boundary. CONSTITUTION:A trigger pulse generated from a control circuit 11 is provided to a transmitter 12 from which an ultrasonic carrier frequency pulse signal is applied to a transmitter/receiver 14 through a transmission-reception switching circuit 13. Consequently, the transmitter/receiver 14 is excited to emit an ultrasonic pulse into water. The reflected signal from the bottom 15 of water is received with the transmitter/receiver 14 to be converted into an electrical signal, which is received with a receiver 16 via the transmission-reception switching circuit 13. Here, until the reflected signal from the wave propagation characteristic boundary, namely, the bottom 15 of water is received, the gain of the amplifier in the receiver 16 is kept suppressed and thus the gain of the receiving amplifier is elavated by an STC signal from an STC signal generator 26 from the proximity of the reception of the reflected signal.

Title: Leaking-liquid detecting apparatus
Inventor: SATO HIROSHI
IPC: G01N27/07
Filed: 1989-04-11
Abstract: PURPOSE:To improve detecting accuracy by preventing erroneous detection at an input stage of measured data and a judging stage for leaking of liquid. CONSTITUTION:The electric characteristics of a sensor 1 are changed by the occurrence of the leaking of liquid. The data in the sensor are read with a data reading means 2. Of all the data of one cycle, the maximum and minimum values are removed and the average value of the remaining data is outputted from an average-data computing means 3 as the measured value. When the output data of the means 3 exceed an allowance value (a) or the changing amount per unit time exceeds the allowance value, an abnormality detection signal is outputted from an abnormality detecting means 4. When the abnormal signals are outputted continuously at least twice, a leaking-liquid judging means 5 outputs a leaking-liquid detection signal (b). Thus the highly precise detection of the leaking of liquid can be performed.
