Title: Magnetic bias device
Inventor: IWATA MASAO
IPC: G11B11/105
Filed: 1987-12-21
Abstract: PURPOSE:To reduce a control current passing through an exciting coil by dispos ing a permanent magnet capable of rotating internally of the exciting coil of a frame form and obtaining a vertical magnetic field by the permanent magnet. CONSTITUTION:The permanent magnet 10 capable of rotating is mounted in the exciting coil 14 of the frame form an held by a magnetic holder 11. When the current passes to the coil 14, the magnetic field is generated and the magnet 10 and the holder 11 are integrally rotated around a rotating axis. A rotation central line 15 coincides with the magnetic field direction of the coil 14. When the current passing through the coil 14 is reversed, the direction of the magnetic field and the orientation of the magnet 10 are inverted according to the rotation. According to the constitution mentioned above, the scale or the direction of the current passing through the coil 14 are controlled, and then, the magnetic field of the coil coincides with the direction of the field of the magnet 10. Then, the rotation is stopped to make a vertical magnetic filed strength biased to a medium disk face maximum. Consequently, the current passing through the coil 14 is reduced to reduce a response delay due to a self-heating or an inductance.

IPC: G01M3/26
Filed: 1990-11-27
Abstract: PURPOSE:To enable highly accurate measurement in a short time by setting a high pressures reservoir tank associated with a high pressure piping system equal, in capacity, to that of a low pressure reservoir tank associated with a low pressure piping system. CONSTITUTION:The capacity of a high pressure reservoir tank 22 associated with a high pressure piping system and the capacity of a low pressure reservoir tank 24 associated with a low pressure piping system are set to be equal to each other. For example in a test by means of a transient pulse method, after a specimen 26 is stabilized by applying a restricting pressure, a valve 36 is closed while all other valves are opened. The a gap pressure is applied via a valve 35 and the valve 35 is closed when a predetermined pressure is reached. Valves 33,34,37 are closed when pressure in a closed section is stabilized, while the valve 35 is opened to apply pressure pulses to the tank 22, and then the valve 35 is closed. After the pressure in the tank 22 is stabilized, the valve 34 is opened and differential pressure  P is measured by a differential pressure sensor 48. Since the capacities of the reservoir tanks 22,24 are set equally to each other with the piping systems included, a test can be performed in a short time.

Title: Gas sensor temperature compensating device
Inventor: IMAMURA HIROO
IPC: G01N27/04
Filed: 1992-11-10
Abstract: PURPOSE:To make constant the temperature of a gas detecting element by forming a feedback loop to heat a heater thermo-coupled with the gas detecting element. CONSTITUTION:When a sensor resistance Rs is heated, its resistance value becomes small and also a voltage output from a calculation amplifier OP1 becomes small. The heating of the sensor resistance Rs is, however, continued by a feedback loop comprising the amplifier OP1, an amplifier OP2, a sample hold circuit 14, an amplifier OP3, a transistor Tr, a heater resistance Rh, and a sensor resistance Rs. Then when the sensor resistance Rs is heated to a specified temperature, and a reference voltage Vref1 output from a reference voltage supply section 13 becomes equal to a voltage output from the amplifier OP1, the heating of the heater resistance Rh is stopped to come in a steady condition. Under this condition, the gas density can be measured.

Title: Serial transmission equipment
Inventor: KONDO TOMOJI
IPC: H04L7/00
Filed: 1988-12-21
Abstract: PURPOSE:To surely perform handshake by detecting the busy state of a slave by a master, and generating the next serial clock(SCL) awaiting the ready state of the slave. CONSTITUTION:By setting the SCLi at 0 in the busy state successively by the slave 2, the SCLd goes to 0 since it is the wired AND of the SCLc and the SCLi, and noncoincidence in a waveform is obtained where the SCLc is set at 1 and the SCLd at 0. Therefore, an SCL noncoincidence signal (f) that is the output of an EXOR gate 8 goes to 1, and an OR gate 4 gates a clock (a), and a frequency divider 5 is stopped, then, the SCLc holds 1 and is stopped. When the slave 2 is set at the ready state, the gate of the clock (a) by the OR gate 4 is released, and the frequency divider 5 restarts the generation of the SCLc. In such a way, it is possible to confirm the busy state of the slave by the master, and to surely perform the handshake of byte unit between the master and the slave.
