Filed: 1995-03-17
Abstract: PURPOSE: To prevent accidents due to oxygen poisoning, by providing a safety valve supplying high partial pressure oxygen only at a certain condition in an oxygen supply line like a man lock, so as not to actuate it at a higher pressure than a specified value. CONSTITUTION: A safety valve 4 with restrictive conditions, which does not work in a higher pressure than a certain value, is provided in a man lock gradually returning to the atmospheric pressure after works in a high pressure chamber like works in a caisson, or an air pipe 5 supplying oxygen to a repressurizing chamber 1. Workers breathe mixed gas from a breathing mask 8 connected to a mixed gas supply pipe 7, while the pressure in the repressurizing chamber 1 is still high, and put a breathing mask 9 connected to a high partial pressure oxygen supply pipe 5, when the pressure decreases gradually and breathe alternately the high partial pressure oxygen and the air in the repressurizing chamber 1 in order to inure themselves. In this way, it is prevented to breathe a high pressure oxygen.

Title: Yoke type thin film magnetic-resistance head
Inventor: NAMIKATA RYOJI
IPC: G11B5/39
Filed: 1995-03-17
Abstract: PURPOSE: To shorten a magnetic path length and to improve a reproducing output. CONSTITUTION: A magneto-resistance element layer 51 is formed on a surface of a non-magnetic substrate 50. The change of an electric resistance value of the magnetic-resistance element layer 51 is detected by a voltage drop owing to a sense current flowing through between lead conductors 52a, 52b. The change in the electric resistance of the magneto-resistance element layer 51 causes by the change in signal magnetic field led from two yokes 53a, 53b to the magneto-resistance element layer 51. A magnetic gap 54 is formed between the tips opposing each other of two yokes 53a, 53b, and the gap detects a magnetized pattern recorded on a magnetic recording medium in the state that it is abutted on or closed to the magnetic recording medium.  Even when the magnetic gap 54 becomes narrower, a part through which the signal magnetic field led by the magneto-resistance element layer 51 passes may be widened, and the excellent reproducing output is obtained.

Filed: 1987-03-13
Abstract: PURPOSE:To detect a direction in operating access, by setting a distance between a pair on one side of wobble bits and a clock bit larger than a specified grade, and changing the distance repeatedly at every information track. CONSTITUTION:Bits 1-4 and a bit 5 constitute the pairs of wobble bits respectively, and the bit of every pair is deviated a little from the axes of track centers 7-10. The distance between the bits 1-4 and the bit 5 is deviated respectively. The distance between the bit 5 and the clock bit 6 of an information data is kept constant. The bit 6 becomes the clock reference of a recorded information data. The structure of a servo field is formed in cyclic structure of 16 tracks by continuing the same four tracks. Also, it is permitted to set the distances between the wobble bit and the clock bit in more than three grades instead of four grades. In such a way, it is possible to detect the direction in operating the access, and to improve the resolution of track count.

Filed: 1979-05-15
Abstract: PURPOSE:To reduce the scanning for the selection signal by securing the synchronism between the data sent out of the circuit which converts the selection signal and the scan signal transmitted from the central control unit of the exchange. CONSTITUTION:The binary coded selection signal is applied to each D-terminal of D-type FFs 206-209. At the same time, D-type FFs 205-209 latch the selection signals with the rise of the output of AND circuit 210 to which the strobe signal is supplied. On the other hand, the scan signal is applied to the CP terminal of J-K type FF212 through NOR circuit 211, and at the same time gives the gate control to open collector NAND circuits 200-204 to secure the data input to the central control unit. With the fall of this pulse, FF212 is latched, and its output Q' is changed from H to L. As a result, FFs 205-209 are all cleared, and output Q turns to L to close the NAND gates of open collectors 200-204.
