Title: Television receiver provided with scanning speed modulation circuit and contour emphasis circuit including the modulation circuit
Inventor: MATSUMOTO KENICHI
IPC: H04N5/208
Filed: 1993-11-09
Abstract: PURPOSE:To prevent power consumption from being considerably increased even when a signal having lots of high frequency components such as a noise is received by a scanning speed modulation circuit 100 being a component of a video image contour emphasis circuit. CONSTITUTION:A video signal received at an input terminal 10 is processed by a scanning speed modulation signal processing circuit 20 and amplified by a variable gain amplifier circuit 30 and an amplifier circuit 40 and the amplified signal is fed to a scanning speed modulation coil 200 by an output circuit 50 to emphasize a contour of a video image. A current detection circuit 70 detects a mean current of the output circuit and a comparator circuit 80 compares the current with a reference voltage. When the former exceeds the latter as the result of comparison, the gain of the amplifier circuit 30 is reduced to suppress a current flowing to the output circuit 50.

Title: Protective gas preflow time control device of gas metal arc welding machine
Inventor: KIMU JIYONNHII
IPC: B23K9/10
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To enable the generation of an arc without a pre-flow time by simultaneously executing wire feeding, shielding gas feeding and arc interrupting when a torch switch is off. SOLUTION: A hose 3 extending from a shielding gas bottle 1 is provided with a solenoid valve 6 which supplies the shielding gas together with wire to a torch 7. When the torch switch of a welding power source section 2 is turned on, only the shielding gas solenoid valve 6 turns on and only the shielding gas is pre-flowed. When the second switch is turned on during the pre-flow time, the wire feeder is operated and simultaneously voltage is impressed to generate the arc, enabling welding. When the torch switch is turned off, the interruption of the wire feed, the interruption of the shielding gas supply and the interruption of the arc are simultaneously carried out. As a result, the labor for waiting for the generation of the arc during the shielding gas pre-flow time is eliminated.

IPC: F24F7/007
Filed: 1990-10-17
Abstract: PURPOSE:To eliminate periodical calibration made by using standard gas by a method wherein an automatic calibration function is provided for a ventilating fan combined with a carbon dioxide gas concentration sensor. CONSTITUTION:An open air introduction detecting means 11 detects introduction of the open air to a ventilating fan body 4 to start a calibrating means 12. The calibrating means 12 determines a difference between an output from a correcting means 7 and an output from a carbon dioxide gas concentration sensor 5 to rewrite a correction value of a correction memory means 6 one by one. When a ventilating fan body 4 is stopped by a drive means 10 after a lapse of a specified time, a blower 1 is stopped, a shutter 2 is closed, and outdoor air is shut off. An open air introduction detecting means 11 stops the calibrating means 12 through detection of the stop of introduction of the open air and the correction value storage means 6 holds a value at a current point of time as a correction value to output the value. The output value of the correcting means 7 is calibrated each time the ventilating fan body 4 is started even when the output value of the carbon dioxide gas concentration sensor 5 is changed owing to a change with a year. As noted above, the ventilating fan realizes an automatic calibration function and eliminates periodic calibration of the carbon dioxide gas concentration sensor 5 effected by using standard gas.

Title: Nonvolatile semiconductor storage device
Inventor: KOBAYASHI MASANORI
IPC: H01L29/788
Filed: 1988-11-07
Abstract: PURPOSE:To remove a limit to a large-scale integration by a method wherein a diffusion concentration of a source of a FAMOS is made higher than the diffusion concentration of its drain and the diffusion concentration of one part of a channel part on the side of the source is made higher than a concentration of a substrate of the FAMOS in order to lower the level of a write voltage to an operating voltage level. CONSTITUTION:A diffusion of N for a source 21 is made denser than the diffusion of a drain; also a part 25 is made dense. When a circuit 12 is controlled, a VSS is connected to a source 10 of a FAMOS. During this process, since an electric field is applied to depletion layers 22, 27 and a field strength in these layers does not become so strong for a write operation, an erroneous write operation is not executed. During the write operation, a circuit 5 is closed and a circuit 6 is opened; a write route is opened. At this point of time, the drain and the source 10 of the FAMOS is reversed; a junction participating in the write operation becomes depletion layers of the 21 and 25. The depletion layers 21, 25 are very small with reference to a junction during a readout operation because a concentration of an N-diffusion region and a concentration of the part 25 in a substrate are particularly high; the field strength is very high. Accordingly, a voltage of a control gate and the drain during the write operation is a VCC as an operating voltage; this voltage is sufficient for the write operation.
