Title: Magnetic disk device
Inventor: NAKAMURA MASAO
IPC: G11B21/08
Filed: 1987-02-23
Abstract: PURPOSE:To improve the settling characteristics of a magnetic head when it is decelerated and stopped by offsetting the drive current of each energizing phase of a stepping motor under a seeking operation according to the lettering offset value set right before start of the seeking operation. CONSTITUTION:It is supposed that a magnetic head is stopped at a position equivalent to a phase A right before start of a seeking operation. In face, however, a drive current of A' due to the urgency given from the drive current in offset for correction of the relative position variance between the magnetic head and a magnetic disk medium. Thus the drive currents B'-D' having the electrical value difference DELTAtheta between currents A and A' are obtained before the seeking operation is started. Then a table is produced for display of those drive currents A'-D' and the current directions and the current values are successively designated according to said table. Thus it is possible to improve the rise characteristics right before start of the seeking operation, i.e., when a stepping motor is accelerated. Then the settling characteristics of the magnetic head can be improved when it is decelerated and stopped.

Title: Gas controlling equipment
Inventor: KAIUSHI AKIRA
IPC: F24C3/12
Filed: 1995-03-01
Abstract: PURPOSE: To prevent occurrence of a fire or the like due to an abnormal rise in the temperature of stuff to be cooked, by constructing a temperature sensor of a plurality of PTC elements being different in a set temperature, by controlling a primary solenoid valve by the PTC element of a high set temperature and by controlling a control solenoid valve by the PTC element of a low set temperature. CONSTITUTION: When the temperature of stuff to be cooked rises for some reason and reaches a set temperature in the course of cooking the stuff, the internal resistance of a first PTC element 42 increases rapidly, a voltage of a battery 47 impressed on a control solenoid valve 29 lowers and thereby the control solenoid valve 29 is closed, while gas is supplied to a burner 6 for a cooking appliance through a bypass passage 33 and thereby the heating power of the burner 6 is reduced. When the temperature of the stuff rises further and reaches the higher set temperature even when the heating power of the burner 6 is reduced, the internal resistance of a second PTC element 43 increases rapidly, a voltage of the battery 47 impressed on a primary solenoid valve 17 lowers and thereby the primary solenoid valve 17 is closed.  Thereby the supply of the gas to the burner 6 is stopped and the burner 6 is extinguished.

Abstract: PROBLEM TO BE SOLVED: To improve the retrieval accuracy and to produce the retrieval knowledge to which the guidance information is reflected by showing a guidance object in a set of words and calculating the degrees of remembrance between the retrieval word and the words of the set based on the appearance frequency of these words to decide a set of retrieval solutions. SOLUTION: A morpheme analysis part 10 decomposes an explanation text to be guided into words and stores them in a text file 20 with only the noun having its analyzed morpheme defined as an extracted word together with the explanation text of every object to be guided. A retrieval part 30 retrieves the file 20 based on an input retrieval word and transfers a set of explanation texts of guidance objects (a set of tentative retrieval solutions) together with the extracted word whose morpheme is analyzed. A remembrance decree calculation part 40 and an association degree calculation part 50 calculate the the average of the remembrance degree, i.e., the association degree between the retrieval word and the extracted word.  A tentative retrieval solution updating part 60 extracts the guidance objects larger than the prescribed threshold and stores them in a tentative retrieval solution set storage part 70. A retrieval solution set output part 90 acquires the final retrieval set via an iteration control part 80 and outputs it as a retrieval solution set.

An air-fuel ratio of the internal combustion engine M1 is controlled in a target air-fuel ratio by a control means M6 according to respective control results. In this case, the air-fuel ratio of the internal combustion engine M1 is leaned by a leaning means M7, and operations of the first and the second respective control parts M6a and M6b in the control means M6 are stopped at this leaning time by a stopping means M8. After it is leaned, a detecting means M9 detects time when a detecting value of the downstream side concentration sensor M5 exceeds a prescribed value. Operation of the second control part M6b is stopped by a stopping means M10 until rise time after it is leaned further.
