IPC: G06T11/80
Filed: 1989-01-27
Abstract: PURPOSE:To erase only the desired pictures by rejecting the erasion requests to the drawn pictures to which the drawing requests are given with the erasion unable attributes when the drawing requests are received. CONSTITUTION:When an erasion request is given to a drawn picture, the picture to which a drawing request is given with an erasion enable attribute at a drawing request can be erased by an erasion request in an erasion state requested to a drawn picture display means 103. For this purpose, the display is instructed to a display device 105. Then the erasion request is rejected to such a drawn picture to which a drawing request is given at a drawing request with an erasion unable attribute. Thus it is possible to erase only the desired pictures.

Filed: 1981-02-12
Abstract: PURPOSE:To increase the reliability of a controller and to improve the plant operating rate, by discriminating failures in two detectors based on two input process variables and an input process variable calculated from an output process variable. CONSTITUTION:A process variable (b) is detected 8, and process variable (a), is detected 3A, 3B and applied to a control variable signal diagnostic section 73. If a detector 3A is in failure and 3B is normal, a switch 74 is switched with an output (k) and a normal signal dB is applied to a control signal generating section 71. At the same time, a normal signal (l) is outputted. In the section 71, a manipulated variable (g) is calculated based on the signal dB and a set signal (f) outputted from a control panel 4 and applied to a controller 2. If the detector  3A is normal and the 3B is in failure, the switch 74 is switched as shown in  figure. On the other hand, if the detectors 3A, 3B are both  in failure, an abnormal signal (m) is outputted and the manipulated variable (g) is stored to a  value immediately before the output of the signal (m), allowing to keep a control signal (h) and the variable (a) constant.

Title: Drawing and stretching method of steel products
Inventor: NAGAI MASAYUKI
IPC: B21C3/14
Filed: 1989-01-27
Abstract: PURPOSE:To enlarge the range in which drawing is possible and to decrease the damages of a die and a plug which are generated in the top-peak part and the generation of seizured flaw of steel products by drawing the working nose part of the material to be drawn while maintaining at higher temperatures than the temperature of other part. CONSTITUTION:On the drawing of metal, the top-peak phenomenon which is that the drawing force becomes larger than the force at a steady part occurs at the starting part of working. The first point on the generation of top-peak is that, at the time of drawing, the coefficient of friction of a lubricant applied to the surface of steel products differs at a rest time from at the time of continued sliding motion. Then the second point is that the top-peak is generated in the non-steady part in which plastic deformation is started abruptly i.e. in the material 3 to be drawn at the place where the clearance between a die 1 and a plug 2 is smallest. Therefore, the top-peak is dissolved by drawing while maintaining the working nose part of the material 3 to be drawn at higher temperatures than the temperature of other part. Accordingly, the drawing is performed by a small drawing force and without the damage of the die 1 and the plug 2 and the generation of seizure or break of the steel products.

Title: Semiconductor relay
Inventor: FURUMOTO NORITERU
IPC: H03K17/78
Filed: 1993-02-05
Abstract: PURPOSE:To prevent an excessive current from flowing between a drain and a source of an output MOSFET by providing an enhancement MOSFET whose gate and drain are short-circuited between a gate and a source of the output MOSFET. CONSTITUTION:A charging current of a static capacitance of a gate of an output M0SFET3 and a current flowing to a drive transistor(TR) 5 both flow to a resistor 4. A drain and a source of the drive TR5 are interrupted by a voltage generated across the resistor 4 to charge a gate static capacitance of the M0SFET3 efficiently. As a result, the state between output terminals 8a, 8b changes from a high impedance state to a low impedance state. On the other hand, since an optical signal from a light emitting diode 1 is lost when the input signal is interrupted, a photoelectromotive force of a photo diode array 2 is lost. Thus, the charge having been stored in a static capacitance of the MOSFET 3 and a static capacitance of a gate of an enhancement MOSFET6 is going to be discharged. The discharge is executed through the TR 5 and then the state between the output terminals 8a, 8b restores to the high impedance state.
