Title: Magneto-resistive head
Inventor: YOSHIDA AKIRA
IPC: G11B5/39
Filed: 1995-04-07
Abstract: PURPOSE: To suppress the influence of vertical bias magnetic fields on a soft magnetic bias film 3 of a magneto-resistive head utilizing the vertical bias by a hard magnetic material 5. CONSTITUTION: While the hard magnetic bias part 5 is joined to an end region 14 of a magneto-resistance effect film the bias part is not formed in junction with the soft magnetic bias film 3 and is formed via a nonmagnetic layer 2. As a result, the vertical bias magnetic fields by the hard magnetic bias part 5 to the soft magnetic bias film 3 are decreased and, therefore, the magnetic saturation of the soft magnetic bias film 3 is promoted.

Title: Method for controlling stepping motor
Inventor: SUNAGA HARUO
IPC: H02P8/38
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To drive a stepping motor in a wide usage temperature range, under optimum drive conditions, and with a single drive source by performing drive with a drive pattern corresponding to a detected temperature division. SOLUTION: A memory 22 of a control part 20 stores the correspondence table between a temperature division and a drive pattern. Also, a central processing part 21 outputs the drive pulse of a stepping motor 1 to an output port 23 by a start signal from the outside, but a temperature sensor 3 detects temperature near the stepping motor 1 at that time for transmitting to an A/D conversion part 25. Then, analog output from the temperature sensor 3 is converted to digital output and is transmitted to the central processing part 21. Then, the central processing part 21 reads the correspondence table between the temperature division and the drive pattern stored in the memory 22 and outputs a drive pulse to the output port 23, thus driving the stepping motor with a single drive source and an optimum drive pulse for enabling usage in a wide ambient temperature range.

Title: Return safety gas shutt-off valve
Inventor: MIZUKOSHI JIROU
IPC: F23N1/00
Filed: 1984-04-24
Abstract: PURPOSE:To improve safety against leakage of gas, by a method wherein, in a gas shut-off device with an electromagnetic device, a valve is adapted to be opened and returned only when a gas pressure on the downstream side is adjusted to a given value at which safety is ensured. CONSTITUTION:A return safety device S adjusts the actuation of an auxiliary diaphragm 19 through adsorptivity of a magnet 21 for holding and a yoke 22 and the elastic force of an adjust spring 23. When a gas pressure is adjusted to a given value, a stopper pin 18, released from holding made through the adsorptivity of the magnet 21 and the yoke 22, is momentarily drawn, and an actuating knob 17 can be depressed. However, if gas leakage occurs, when a gas pressure on the downstream side is not increased even if, with a pilot valve 8 opened, gas is injected through a pilot nozzle 6, the auxiliary diphragm 19 is inoperative, and as a result, the stopper pin 18 is not moved from a position allowing the stopper pin to be engaged with a stopper 11. This state is found through visual watching of a pressure indicating body 20 from the outside of a clear cover 27. Lifting up of a control knob 17 is stopped, a pilot nozzle 6 is covered with a pilot valve 8, and a piping on the downstream side is checked for gas leak, which is in need of repair.

IPC: F02P5/15
Filed: 1992-03-05
Abstract: PURPOSE:To simplify the structure by comparing knocking signal with a back ground level both of which are detected so as to make knocking judgement. CONSTITUTION:A knocking signal S1 and a valve knock-sound signal S2 are included in a signal (a) from a knock sensor 7. An output signal of a buffer filter 15 is converted into the waveform of a signal (b) in a retification integrating circuit 16. A CPU 12 computes a timing t1 expected to occur the knocking and a timing t2 expected to end the occurrence of the knocking on the basis of the output signal of a waveform shaping circuit 11. Next, a timing B when neither knocking nor valve knock-sound is produced is computed on the basis of the output signal of the waveform shaping circuit 11. Moreover, a signal for clearing the value of a maximum value detecting circuit 17 is output at a timing t1, the value of the maximum value detecting circuit 17 is read in A/D for storing them as a knocking signal. And then an A/D conversion value of a signal (b) is read in at the timing B for storing them as a background level. By comparing the taken-in knocking signal with taken-in background level if the former is larger than the latter, it is judged that knocking occurs, on the contrary, if the former is smaller than the latter, it is judged that no knocking does not occur.
