Abstract: PURPOSE:To quickly migrate a motor-driven air blower to a desired input. CONSTITUTION:After the start, input control of a motor-driven air blower F and a motor B is executed in accordance with a mat control law of a storage means 26. Thereafter, the kind of the floor surface is detected by a floor detecting means L, and whether it is a wooden floor, or a mat, or a short-haired carpet, or a long-haired carpet is detected. In accordance with the detected kind of the floor surface, the input control of the motor-driven air blower F and the motor B is executed. At the time of start, the start is always executed from a mat law of an intermediate input, therefore, it can be migrated quickly to a long-haired carpet, a short-haired carpet or a bare board floor, and operability of the vacuum cleaner is improved. Since the cleaning capacity immediately after the actuation is improved, cleaning can be executed quickly from immediately after the actuation.

Title: Method for spreading nucleic acid cluster
Inventor: TOKITA JIRO
IPC: C07H21/04
Filed: 1994-02-14
Abstract: PURPOSE:To planarly spread a nucleic acid cluster useful as e.g a footing for making fine structures controllable in high accuracy, by charging a solution with the nucleic acid cluster followed by application of an electric field and by taking advantage of the electrostatically attractive force between electric field-forming electrodes and the dipoles produced by the electric field. CONSTITUTION:A nucleic acid cluster 7 is charged in a solution and added and fixed to a desired site of a planar substrate 1 made of e.g. Teflon followed by passing electric current into electric field-forming electrodes 2, 4 to apply an electric field to the cluster to develop, in this cluster 7, a dipole with its vector opposite to that of the electric field to produce electrostatically attractive force between this dipole and the electrodes 2, 4, thus attracting both the left and right ends of the cluster 7 to the electrodes 2, 4, respectively, and spreading the cluster horizontally. Subsequently, an alternate current electric field comparable in intensity to the above-mentioned electric field is applied to generate similar electrostatic attractive force, thus attracting the cluster 7 to extend it perpendicularly. These above-mentioned operations are then repeated several time, thereby planarly spreading the nucleic acid cluster 7 to be used as a footing in making fine structures controllable with accuracy as fine as nanometer order.

Title: Multi-level watchdog timer system
Inventor: MATSUDA MITSUHIKO
IPC: G06F11/30
Filed: 1986-01-29
Abstract: PURPOSE:To extend a fault detecting range to a processing program having a wide range in level and also to shorten the answer time, by providing plural watchdog timers different in level of overflow value in response to the level of the processing program. CONSTITUTION:A processing program A is started by a timer 2 in a prescribed cycle. When execution of the program A is through, a watchdog timer 3a is reset and the execution of a processing program B is started. When execution of the program B is over, a watchdog timer 3b is reset and execution of a processing program C is started. When execution of the program C is through, a watchdog timer 3c is reset. Then a processor is set under an idle state. If either one of those timers 3a-3c has an overflow, this overflow is informed to a fault occurrence detecting circuit 5 via an OR gate 4. Thus an alarm is produced and the processor is switched to a spare processor.

Title: Detecting method for finish time of dry etching reaction
Inventor: INOUE MINORU
IPC: G03F1/84
Filed: 1980-02-15
Abstract: PURPOSE:To detect the finish of the reaction when performing the subject dry etching reaction automatically, simply and in an excellent sensitivity by a method wherein the decision for the finish of reaction is given at the moment when the amount of variation of the quantity of plasma light generated at the time of etching reaction to the time of reaction is reduced below the prescribed value. CONSTITUTION:In the performance of the plasmatic etching reaction, a specific gas, CF4 for instance, is inducted into a reaction tube, the gas is excited and plasma is generated, and as the excited ion in the plasma is reacted to the material to be etched, the plasma light has a characteristic beam of light which appears only in the period while the etching reaction is continued. Therefore, this transforming plasma light such as a fluorine radical light emission, for example, is detected and the finish of the etching reaction is determined when the differential value C of the function indicating the relation between the amount of plasma light emission and the reaction time reaches to a fixed value 1t. Accordingly, the point of time when the etching reaction is finished is automatically detected in an excellent sensitivity and a microscopic pattern can be obtained.
