Title: Gas detector
Inventor: ASHIZAWA YUKIO
IPC: G08B21/16
Filed: 1978-12-28
Abstract: PURPOSE: To enable to display during malfunction avoiding time with freedom from anxiety practically, by avoiding initial malfunction at normal atmosphere and operating alarm unit after a given time under gas atmosphere.  
     CONSTITUTION: The circuits of 6W11 rectify and smooth the A output of the gas detection element 5. The constant voltage circuits consisting of 12, 13 divide the constant voltage with the resistors 14, 15, and obtain the comparison voltage B. The said voltages A, B are compared at the voltage comparator 25 to obtain the C output. The C' output is obtained from the C output by switching the both ends of the resistor 18 of the voltage divider consisting of 16W18 with the inversion circuits, two stages, consisting of 21, 22, 28. From the circuits 19, 20, the output D leading exponentially from the start of conduction can be obtained. C' and D are compared with the voltage comparator 24 to obtain E output. AND circuits 31, 32 are conductive when the both of C, E outputs are at 1, and F output is given across the alarm circuit 33. Thus, initial malfunction can be avided under normal atmosphere, and the alarm unit is operative after a given time at the start of power application under gas atmosphere.

Filed: 1989-06-28
Abstract: PURPOSE:To execute the decimal subtraction at high speed by storing the result of subtraction in a second register and storing zero from a zero generation circuit in a first register. CONSTITUTION:A micro-instruction DSUB is decoded by a micro-instruction decoder 9, and the result of subtraction is loaded on a target register 4, and loaded on a source 2 register 2, as well through a bypass route 11-1.

Subsequently, a micro-instruction RECOM is decoded by the decoder 9, and a zero generating circuit 8 loads zero on a register 1 and executes decimal subtraction. Next, a target register load generating circuit 7 decides whether the result of subtraction is loaded on the register 4 or not by the contents of the register 6. When a load signal which the circuit 7 sends to the register becomes active, the result of subtraction is loaded, and it is not loaded when the signal is inactive. In such a manner, the decimal subtraction can be executed at the high speed.

Title: Apparatus for preventing heat layer condition within feed water pipe of steam generator
Inventor: PATORITSUKU SANDEMEERU
IPC: F22D7/06
Filed: 1988-06-30
Abstract: PURPOSE: To prevent thermal stratification in a feed pipe of a steam generator by combining a helix adapted to partially cut cold water and a rising break part formed by a dual bend in the feed pipe. CONSTITUTION: Upstream and downstream parts 11 and 13 of a feed pipe are made horizontal and the downstream part is arranged somewhat at a higher level to form a rising vertical break part while the central part 12 is inclined at an angle to the plane. A fixed helix 14 is arranged within the downstream part 13. Cold water enters a lower part reaching the helix 14 and comes into a channel 17f and further the channels 17g and 17d. The channels are all set at a higher level than the cross section of an inlet and cold water gathers to the upstream side of tile helix 14, gradually raising the level thereof. This action continues until the cold water reaches a height (h) corresponding to the lowest point of the channel 17s while the cross section of the channel 17s has a height decreasing from the cross section of the inlet and hot water fills the remaining part of the pipe.  The cold water begins to flow into the upper channel 17s which has a downward inclination and freely flows over the helix 14.

Title: Facsimile reception method
Inventor: TAKEDA MASAYUKI
IPC: H04N1/00
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To eliminate communication errors by erroneous operations by automatically switching a line to a facsimile reception state, then continuously performing facsimile communication and automatically disconnecting the line after it is ended at the time of disconnecting a telephone line. SOLUTION: When the call termination of the telephone line is voice, communication is performed with an opposite party. When it is ended and a receiver is placed, a control part 7 switches the line to a facsimile circuit 3 by a communication switching circuit 4 and turns it to the facsimile reception state. On the other hand, in the case that the opposite party is a facsimile, an operator presses a start button 5 and switches to the facsimile circuit 3. In the case that the receiver is placed without pressing the start button even though the opposite party is the facsimile, the control part 7 automatically switches the telephone line to the side of the facsimile circuit 3. In such a manner, at the time of disconnecting the telephone line, when the receiver is placed without switching to the facsimile reception state, by automatically attaining the facsimile reception state for fixed time, the communication errors are eliminated.

Title: Coordinate data input device

IPC: G06F3/0487
Filed: 1987-06-30
Abstract: PURPOSE:To minimize the shear of a display position of an input pen by constituting the titled device so that the detection of positional coordinates is neglected when the input pen lightly depresses a tablet. CONSTITUTION:When the input pen 6 depresses the tablet 1, a control circuit 10 detecting the depression closes switches 9A, 9B on the basis of a received switching signal S to set up the detecting state of the X coordinate of the pen 6, executes current-voltage conversion and compares an output voltage X1+X2 with a specific value XK in a data memory 12. When the output voltage is larger than the XK, the X coordinate of the pen 6 is found out and stored in the data memory 12. The circuit 10 reads out data from the memory 12, writes the read contents in an image memory 13 and displays the position of the pen on a display device 14. When X1+X2 or Y1+Y2 is smaller than the specific value XK, the circuit 10 neglects the detection of the positional coordinates of the pen 6 to prevent data from being displayed on a sheared position.
