Abstract: PURPOSE:To prevent the electrostatic damage of a semiconductor device by sealing the device with resin having electrical conductivity of the degree which does not affect the influence of the operation of the device. CONSTITUTION:Electrodes S, D are attached to N type source and drain layers 2 of a P type Si substrate 1, gate electrodes G1, G2 are formed on a gate oxidized film 3, and a P type layer 5 in an N type layer 4 is coupled to the electrodes S, G1. Carbon powder is mixed with epoxy resin to provide suitable conductivity in resin 6, and the resin 6 is used to seal. Parallel resistors R1, R2 are inserted to the protective diodes D1, D2 between the source and the gate, the resin can become the leakage pass of static electricity, and when the resistance between the electrodes is selected to approx. 5MOMEGA by regulating the mixed amount, the influence to the operation of an FET is reduced, and in case of high  frequency FET, the leakage is approx. 1muA. According to this configuration, the  static damage resistance for the FET can be improved.

Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical traveling type escape guiding system capable of preventing the generation of misguide to a dangerous place by indicating escape route with a proper guide pattern matching with the actual circumstances of a warning section. SOLUTION: Guide pattern operation information including all light emitting unit group information belonging to each of warning sections A to H as light off information to be the start point of the guide pattern is stored in a storage part by a setting means. In the warning section C e.g. only a light emitting unit group (e) is set up as a start point, but in the warning section B, both light emitting unit groups (b), (d) are set as start points. When movement information is generated in the section B, the unit groups (b), (d) are turned off and a guide pattern getting away from the section B is flashed by the light emitting unit groups (a), (c), (e), (f), so that the generation of misguide to the dangerous warning section B is suerely prevented.

Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To restore a setting function efficiently without provision of a specific key by cancelling a function selected by a selection means and not decided by a decision means in response to an external operation and allowing a multi- function device to execute a function having been set before the selection. SOLUTION: An operator depresses a menu key 32 to display a menu on a display section 18, selection keys 34, 36 or the like are used to select a function of a monochromatic copy and a setting key 38 is depressed finally, then the content selected by the function setting mode is decided and stored as it is to be used for a succeeding copy control function. However, in the case that the operator selects one a function in the function setting mode but desires to cancel the selected content and to make a copy immediately in the default state, the setting is restored to the default setting by having only to depress a copy start key 42 without restoring the selected setting, and the copying is made according to the default contents.

IPC: C21C5/46
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent the jetting of gaseous oxygen to a portion which does not stick skull, by inserting a jig into a side hole faced to the portion which does not stick the skull when the skull stuck onto a converter is removed by jetting the gaseous oxygen. SOLUTION: When the skull stuck onto the converter is removed by jetting the oxygen from the side holes 2b opened at the upper part from a tip lance hole at the pretreatment of molten iron, the control jig 1 is inserted into the side hole 2b faced to the portion which does not stick the skull, and the side hole 2b is closed to regulate the jetting of the gaseous oxygen. The shaking of a plate-like pendulum 1b attached pivotally with a pin 3 at the tip part of the jig body 1a so as to be freely shakable to the jig body 1a, is regulated so as not to project from the extended line in the longitudinal direction of the jig body 1a to only one direction with a stopper 1c fitted to the jig body 1a.  When the jig body 1a inserted into the jetting hole 2b reaches the position along the inner peripheral surface of the inner tube 2c of the main lance 2, a flange 1d is abutted on the outer tube 2d to stop the insertion. In this way, the erosion of the furnace wall refractory can be prevented.

Title: Detector for fault of circuit including coil
Inventor: TOKI SHIYUUICHI
IPC: G01R31/72
Filed: 1982-03-15
Abstract: PURPOSE:To minimize influence upon a working current flowing through a circuit including a coil and a voltage applied to the coil by monitoring only counter electromotive force and generating a fault signal. CONSTITUTION:When a transistor (TR)Q1 is turned on by an energizing current, a primary coil 2a is energized. Once the energizing signal is ceased, the TR Q1 is turned off to generate counter electromotive force across the primary coil 2a. The Zener voltage of a Zener diode ZD1 is higher than a battery voltage VB and much lower than the voltage by the cunter electromotive force, so once the counter electromotive force is generated, the current flows through the ZD1, whose anode voltage is divided by resistances R1 and R2 through a diode D1. This divided voltage is compared with a prescribed voltage Va by a comparing circuit 3. When the energizing signal is ceased, the circuit 3 operates to generate a low-level output when the divided voltage is higher than the voltage Va, or a high-level output when latter is low. This high-level output is regarded as a fault signal to turn on a display 4.

Title: Communication network
Inventor: AIDA JUNICHI
IPC: G06F13/00
Filed: 1995-03-01
Abstract: PURPOSE: To reduce disconnection time by comparing the priority of the transmission line in a detour command and the priority of the transmission line of a self-node detour definition and switching and putting back an already detouring command when the priority of the detour command is higher. CONSTITUTION: When the fault in a transmission line is recognized and alarm information is generated in a hard control part 1 1, for instance, the start request of the detour which is pertinent to an alarm portion is performed as a detour command for an operation control part 13, in a fault control part 12. In the control part 13, the detour command from the control part 12 is delivered to a detour processing part 14. When the processing part 14 receives the detour command, the priority of the detour route in the detour command and the priority of the present transmission line defined in the control part 13 are compared. When the former is larger than the latter, a switching and putting back processing is performed under a condition that the command is not a detour. Namely, when the priority is designated to the detour command, the pertinent definition is selected.  When another definition for the same faulty transmission line is already detouring, the definition is made definition selection improper when the priority of the definition selection is low.
