Title: Optical disk recording and reproducing device
Inventor: SATOU ISAO
IPC: G11B7/00
Filed: 1983-09-29
Abstract: PURPOSE:To execute recording and reproducing without discriminating between an additional write type recording disk and an erasion type recording disk, by recording a modulating signal in an optical disk, differentiating a reproducing signal from the optical disk, and reproducing an edge signal of the reproducing signal by a demodulating circuit. CONSTITUTION:A modulating circuit 5 reads out an input data, mingling with each other, and converts it to an RLL (Run Length Limited) code. Said modulating signal 103 inverts a signal in the center of its bit ''1'' by a NRZI converting circuit 6 and generates a recording signal 104. Reproducing signals 105a, 105b are reproducing signals of erasion type and additional write type recording disks, respectively. As for these two reproducing signals, each signal polarity is opposite. Both reproduciang signals are differentiated, and differential signal 106 is outputted. As for the signal 106, a conversion opposite to the modulating circuit 5 is applied by a demodulating circuit 9, and it becomes a demodulated data. The demodulated data written in a scramble buffer 4 is read out by mingling in reverse with an error controlling circuit 3. That is to say, as for both reproducing signals, the polarity of the signal becomes opposite, but the differential signal output 106 is reproduced as a signal similar to the modulating signal 103, respectively.

Title: Magnetic head
Inventor: IKEGAMI TOMIO
IPC: G11B5/127
Filed: 1988-07-21
Abstract: PURPOSE:To obtain the magnetic head small in temperature dependency by including a part, in which magnetic saturation is easily generated, into one part of a magnetic circuit. CONSTITUTION:The magnetic head is composed of an I core 4, an L core 4 to be composed of a ferrite, a back core 2, whose saturation magnetic flux density is effectively low, to be composed of the sintered body of the ferrite and non-magnetic ceramics and a gap part 1. Since the saturation magnetic flux density is small for the back core 2, a magnetic flux goes to be constant in case that recording and magnetizing force over a certain degree is loaded. The recording and magnetizing force for the constant magnetic flux is determined according to the product of a recording current and a coil. Here, since the recording current is caused to be 10mApp, for example, the magnetic flux goes to be constant. Then, with being reflected by this constant magnetic flux, an output voltage goes to be constant without depending on a temperature or the recording current. Thus, the temperature dependency can be decreased for the output voltage of the magnetic head.

Filed: 1989-07-15
Abstract: PURPOSE:To shorten a term of field construction work and to also reduce an installation area by preparing an outer wall from reinforced plastics divided so as to have a circular arc shape in a factory to feed the same in the installation spot and assembling the same on a bottom plate also used as the concrete foundation. CONSTITUTION:An outer wall 2 is prepared from reinforced plastics having a circular arc shape in a divided state in a factory and fed in a field of construction work to be assembled and executed on a bottom plate 1 also used as the foundation preliminarily executed from concrete on the spot. Therefore, the outer wall can be transported without receiving the restriction of a vehicle or a road and a field term of construction work can be shortened. Since the outer wall can be prepared freely in matching relation to a treatment system, a treatment water amount, treatment load quantity and the shape of an installation area, there is almost no restriction of an installation place and an installation area may be small and, therefore, the effective utilization of land can be attained. Since the outer wall 2 is formed into a circular arc shape, the corresponding force of the outer wall is dispersed not only against the soil pressure in case of underground installation but also against the water pressure in case of just-above installation and, therefore, the amount of structural materials may be reduced.

Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To enable a constantly stable discharge of liquid without a change with time even after shipment, even when dispersion in quality and performance of a movable member occurs in the manufacturing stage. SOLUTION: This liquid discharge head is of such a structure that a first liquid flow path 14 communicating with a discharge aperture 18 and a second liquid flow path 16 with an arranged heat generating member 2 are partitioned by a partitioning wall 33 with a movable member 31.
