Title: Magnetic head
Inventor: KAMINAKA NOBUMASA
IPC: G11B5/147
Filed: 1986-03-05
Abstract: PURPOSE:To reduce eddy-current loss and reduce decrease of effective track width due to an interlayer insulating layer by making the interlayer insulating layer laminating soft magnetic thin ferrite films between plural magnetic thin films that constitute a magnetic core. CONSTITUTION:The magnetic core of a magnetic head is constituted by laminating metallic magnetic thin films 6-9 successively between substrates 5 and 13 made of glass, ceramics etc. Ni-Zn ferrite thin films 10, 11, 12 are laminated respectively between metallic magnetic thin films 6 and 7, 7 and 8 and 8 and 9 that constitute the magnetic core. As electric resistivity of ferrite thin films 10-12 is several OMEGA.cm-10<4>OMEGAcm, they function as the interlayer insulating layer and reduce eddy-current loss in the metallic magnetic thin films 6-9. Further, their magnetic resistance is less than several Oe at the highest and show good soft magnetism, and the interlayer insulating layer itself makes magnetic operation, and accordingly, acts as an effective track.

Title: Recording method
Inventor: TAKANASHI RYOYU
IPC: G11B11/00
Filed: 1990-02-28
Abstract: PURPOSE:To allow the addition and conversion of 2nd information to 1st information by recording the 2nd information in superposition to the area of the 1st information recorded on an information recording layer. CONSTITUTION:A DC voltage Va is impressed between the transparent electrode and electrode 15 of a recording medium 30 formed with the transparent electrode on the surface of a photoconductive layer recorded with images 56 of the 1st information. Light 51, such as, for example, laser beam, subjected to intensity modulation in correspondence to the 2nd information is condensed by using an optical system consisting of a laser light emitting device L, an optical scanner 52, a reflecting plate 53, a condenser lens, etc., and the spot of the laser beam 51 is scanned to the prescribed place of the recording medium 30 to record the 2nd information in the recording area 57. The impressed voltage is set smaller than the impressed voltage at the time of recording of the 1st information in this case, by which the overlap recording is executed without changing the state of the 1st information. The addition and conversion of the 2nd information to the 1st information are thus possible.

Filed: 1983-03-23
Abstract: PURPOSE:To enlarge cushion possible range by providing a valve body on a piston in a rack-pinion rotation driving device, thereby blocking a main fluid path communicating with a feed and discharge port. CONSTITUTION:When pressurized fluid is supplied to a port 31a to discharge a fluid through a feed and discharge port 31, a valve body 8a is first pushed to the right to open a main fluid path 32a, so that pressurized fluid enters a piston chamber C2 to push pistons 4a, 4 to the right, thereby rotating a pinion 6 and a driving shaft 60 clockwise.

Title: Ultrasonic distance measuring apparatus
Inventor: MAUE AKIRA
IPC: H03K5/00
Filed: 1982-03-29
Abstract: PURPOSE:To achieve an accurate measurement of distance even when there are variations in the amplitude of a reflected pulse by detecting a zero crossing of a signal following the detection thereof after it passes through a band-pass filter. CONSTITUTION:Employing the output of a zero cross comparator 12 as setting signal and the output of a level discriminator 9 as resetting signal, a flip flop 15 is started by a first signal from the level discriminator 9 and returned by the first signal from the zero cross comparator 12. In this case, a counter 10 is set by a signal (f) delayed by a fixed delay time synthesized with the flip flop 15. As the resetting of the counter 10 is delayed by the same fixed delay time in the integration, the delay time can be corrected. This won't cause substantial errors even when the amplitude of the wave signal received is not constant.

IPC: G05F1/56
Filed: 1994-03-18
Abstract: PURPOSE:To provide a stabilized power source which uses a simple protection circuit and can stably operates even in a half-short state or at power source startup time. CONSTITUTION:A transistor(TR) Q3 serves as a protection TR, a constant voltage circuit 1 generates a detection voltage, and a Zener diode ZD1 and a resistance R1 generate a reference voltage. A TR Q2 operates as a comparison part and a TR Q1 functions as a control part. If a load-side voltage Vo drops owing to the short circuit, etc., of a load, the collector current of the TR Qs begins to flow. Consequently, the base current IB2 of the TR Q2 decreases and the collector current, i.e., the base current IB1 of the TR Qu also decreases. Therefore, a load current It decreases in a fold-back shape as the base current IB2 of the TR Q2 decreases, so that the protecting operation of the TR Q1 is performed.
