Title: Tube joint device, tube joint detecting impedance element and detecting method
Inventor: FUJITA SATOSHI
IPC: F16L47/02
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To detect a tube joint, provided in a hidden place of soil or the like, with high accuracy by connecting tube joint detecting impedance elements to both end parts of a heating wire in an electricfusion-welded tube joint provided with the heating wire inside or on the inner surface of a tube joint body made of thermoplastic synthetic resin. SOLUTION: When an oscillation start command signal is supplied to an oscillating circuit 28 from a control circuit 38 through a line 39, the oscillating circuit 28 generates burst wave, so that electromagnetic field energy from a transmitting coil 27 is supplied to a tube joint device 20 and also supplied to a receiving coil 35. Receive waveform can therefore be obtained from the output of the receiving coil 35. When the excitation driving of the transmitting coil 27 is suspended, the electromagnetic field energy decreases with the lapse of time, and at this time, output obtained from the receiving coil 35 also decreases. A plurality of peak-to-peak value are therefore obtained by a level detecting means 37, and a place where this peak-to-peak value becomes the maximum is detected as the buried place of the tube joint device.

Title: Signal transmission circuit, signal transmission method, a/d converter and solid-state image pickup element
Inventor: KUSUMOTO KEIICHI
IPC: H04N5/378
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To transmit signals at a high speed with small driving power by supplying charges corresponding to input signals to a first capacitor, providing a means for transferring the charges from the first capacitor to a second capacitor and making the second capacitor larger than the first capacitor. SOLUTION: A transfer part 100 outputs the charges corresponding to the input signals to a conversion part 200 and the conversion part 200 receives the charges and outputs signals corresponding to the received charges. When a switch S is changed from OFF to ON, the charges Q0 stored in a capacitor CO are moved to the capacitors C1 and C2. When the capacitor C1+C2 is sufficiently larger than the capacitor CO, the capacitor C1+C2 is as if a ground at the time of viewing from the side of the capacitor CO and the capacitor CO were short-circuited through a resistor R. A circuit time constant becomes C0.R and the high speed signal transmission of low power is performed by making the capacitor CO small.  Also, since the ratio of the charges of the capacitors C1 and C2 is proportional to a capacitor ratio, when the capacitor C2 is larger than the capacitor C1, almost all the charges of the capacitor CO are stored in the capacitor C2.

IPC: H01L21/8242
Filed: 1986-02-04
Abstract: PURPOSE:To improve reliability by reinforcing the resistance to soft errors due to alpha-particles by forming a memory array part of the same conductive type as that of a substrate in a well having high impurity concentration at least ten times higher than that of the substrate. CONSTITUTION:A p<+> well 18 has impurity concentration at least ten times higher than a p<-> substrate 1. In this p<+> well 18, a memory array part is formed. Accordingly, the expansion of a depletion layer produced on a boundary between nN<+> regions 7 and 8 is restrained and the generation of produced charges itself can be reduced, thereby reinforcing the resistance to soft errors. As the difference in potential due to the difference in impurity concentration between the p<+> well 18 and the p<-> substrate 1 functions as a barrier against electrons in the p<-> substrate 1, the gathering of the electrons generated in the p<-> substrate 1 can be also reduced.
