Title: Input protection device for semiconductor device
Inventor: SATOMI TAKESHI
IPC: H01L27/08
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To achieve an input protecting circuit that can increase the potential difference between input voltage and substrate voltage at which leak current is generated by increasing the donor density of a surface by arranging a second conductor type high density diffusion layer around a first conductor type high density diffusion resistance layer and a second conductor type diffusion guard ring layer. SOLUTION: The donor density on the surface of an N<-> epitaxial layer 12 is increased by arranging an N type diffusion layer 17 around a P<+> type diffusion resistance layer 13 and an N<+> diffusion guard ring layer 14 and as the result of it, an N type region under the gate of a parasitic PMOS is harder to be reversed. The potential difference between the input voltage and the substrate voltage at which leak current can be suppressed is controlled with parameters of (1) the depth of the N type diffusion layer 17, (2) the density of the N type diffusion layer and (3) the shape of the N type diffusion layer. Therefore, the potential difference between the input voltage and the substrate voltage at which the leak current is generated can be increased while securing the function of the input protection device.

Title: Liquid film downcoming type vertical heat exchanger
Inventor: SHINKAWA TOSHIKAZU
IPC: F28D3/02
Filed: 1984-03-27
Abstract: PURPOSE:To control the boiling state of liquid film in a heat transfer pipe at its upper part and consequently prevent the liquid film from separating by a structure wherein a heat transfer buffering body is interposed onto the outer surface of the heat transfer pipe at its upper part. CONSTITUTION:A heat transfer buffering body is located onto the outer peripheral surface of the heat transfer pipe at its upper region so as to suppress the heat flow in the direction of pipe wall thickness in said region. The heat transfer buffering body 1 is made of metallic fibers 1'. The heat transfer buffering body 1 contacts with high temperature condensate, resulting in holding liquid water among the fibers due to the surface tension of the water. Concretely, because the condensate generates on the outer peripheral surface of the fibering body 1 due to the condensing heat transfer of steam having saturation temperature and shifts itself in the direction of the thickness of the buffering body 1 by diffusion, the state of coexistence of fiber and water is realized in the buffering body 1 during usage, resulting in enabling to have the thermal conductivity of the buffering body 1 determined by the coefficients of thermal conductivities and the ratio of volumes of the fiber and the water.

Abstract: PURPOSE:To control bipolar action and to avoid a decrease in dielectric strength between a source and a drain by a method wherein drain region width is  broadened more than source region width when a source region and a drain region are formed on a semiconductor substrate and a channel region locating between these regions are spreaded in fan shape. CONSTITUTION:An N<+> type source region 12 and an N<+> type drain region 13 are formed on a P type Si substrate and a gate electrode 14 consisting of polycrystalline Si is formed on a channel region locating between the regions 12 and 13 through a gate insulating film and the circumferences of the regions 12 and 13 are surrounded by a thick field oxide film 11. In this composition, the drain region 13 width is broadened more than the source region 12 width to form the channel region locating between the regions 12 and 13 in sector shape. In this way, electric charge density at the channel becomes lower toward the drain side from the source side and electric field strength decreases at the drain side to control bipolar action and it is possible to prevent a decrease in dielectric strength.

Title: Capacitor type x-ray generating equipment
Inventor: YAMAZAKI KEI
IPC: H05G1/24
Filed: 1984-03-26
Abstract: PURPOSE:To prevent an X-ray tube from breaking even if a high voltage capacitor is switched with it charged by interlocking switching when a detected value of charging voltage of a high voltage capacitor exceeds a specified safety switching value of an X-ray tube. CONSTITUTION:When charging voltage of a high voltage capacitors C1 or C2 is increased and exceeds a specified safety switching voltage of X-ray tube, an operational amplifier AMP detects it, and outputs a signal H, and a contact 1RY1b of a relay 1RY is opened. A bypass circuit of an electromagnetic coil MA or MB formed by an X-ray tube circuit changing switch S1 and a contact 1RY1b is not formed, and the electromagnetic coil MA is kept non-operational. In other words, when charging voltage of the high voltage capacitors C1 and C2 exceeds a specified safety switching voltage of X-ray tube, a circuit is not changed even if switching operation is carried out by the X-ray tube circuit changing switch S1. This prevents the X-ray tube from breaking even if a high voltage capacitor is switched with it charged.

Title: Interaction processing program generation device
Inventor: ISHIKAWA AKIRA
IPC: G06F3/0487
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To attain the interaction processing of a voice response device by generating automatically a program source code that performs the interaction processing based on only the menu hierarchy and the definition of flows of necessary input items. SOLUTION: A programmer who produces an interaction flow of a voice response device describes an information service menu in the grammar that can be interpreted by an interaction processing program generation device. This generation device analyzes the syntax in every sentence and in each processing procedure for the described interaction flow via a procedure/hierarchical structure interpretation part 102 and then stores the menu hierarchy under analysis in a hierarchical structure storage part 101. Then a label production part 103 produces a label to shift the state from the interpreted function name by appending the hierarchy information and inserts the label into an operation definition file 105.  A function parts expansion part 104 retrieves a function parts definition storage part 108 based on a function name and expands the function parts into an interaction processing program that can be interpreted by the voice response device to output it to the file 105. Thus an interaction processing program code that can be interpreted by the voice response device is generated.

Filed: 1988-03-11
Abstract: PURPOSE:To control digital copy to an arbitrary number of times even when one recorded first is analog recording by making different successively copy control signals composed of plural bits every time the digital copy is executed. CONSTITUTION:A signal from an analog input terminal 1 is inputted to a recording signal processing circuit 6 through an A/D converter 2.

When the signal from a digital output terminal 26 including this signal is recorded by another digital audio tape recorder, a discriminating part 11 discriminates the propriety of the digital recording. Consequently, by the change of the bits of the CS, the copy can be inhibited at the prescribed times.
