Title: Information recording medium and information recording system
Inventor: TONO HIROYUKI
IPC: G11B7/2433
Filed: 1987-12-07
Abstract: PURPOSE:To reduce pit diameter and rims and contrive a higher recording density, by a system wherein a substance having a lower boiling point, a lower subliming temperature or a lower temperature for generating a gas through pyrolysis in a recording film is instantaneously changed from a solid stage to a gaseous state, and the force of rapid volume expansion attendant on the change is utilized to blow off a substance having a higher boiling or subliming point. CONSTITUTION:A recording film 12 of a recording medium 15 has a structure in which ultrafine particles of Te with a diameter of not more than 100Angstrom  are dispersed in a C-H compound 27. The evaporating temperature of the C-H compound 7 is 150 deg.C, while the boiling point of Te is 989.8 deg.C. When the recording film 12 is irradiated with a semiconductor laser beam 24 with a wavelength of 830nm by condensing the beam of a diameter of about 1-2mum by a lens 25 and with such a power as to melt even the Te particles, mainly the Te particles 28 absorb the energy of the beam, to cause a temperature rise in the recording film in the irradiated region 29. At this moment, the C-H compound 27 in the recording film 12 is rapidly evaporated with the attendant volume expansion, whereby the Te particles 28 are blown off. By this system, the size of a rim formed can be reduced, as compared with that in a melting system wherein a pit is formed based only on a surface tension at the time of melting.

Title: Communication interface
Inventor: KOBAYASHI KOJI
IPC: G08C15/00
Filed: 1989-11-30
Abstract: PURPOSE:To enhance the reliability of a count value by starting the return of the count value by an (m)-scale counter at the data input timing, and resetting the count value by the (m)-scale counter at its data input completion timing. CONSTITUTION:Until the data fetch completion timing from the data fetch timing, that is, until an acknowledge signal (d) is generated after a data fetch signal (c) is generated, the input of an overflow signal to a counter 7 is inhibited, therefore, a count value by the counter 7 maintains a value by the data fetch timing. In such a way, even when a transmission request is executed again due to a communication error, a count value by an original transmission request timing can be obtained, and reliability of its count value is enhanced. Also, since the count value by the counter 7 is reset by the data input completion timing, an arithmetic processing load in a master station can be reduced. Moreover, since a latch circuit for the count value to be returned is not required, its circuit constitution can be simplified.

Filed: 1994-11-07
Abstract: PURPOSE: To eliminate the clearance between column rows, by outwardly ejecting a solidifying slurry while excavating the space of the first column row formed in advance and widening the excavation area to form the second column row. CONSTITUTION: Columns 11 form a row in a state closely positioned to each other and the distance between two rows is almost equal to the diameter. A second row of columns 13 is formed in the space 12. The excavating shaft 3 is lowered while rotating. A solidifying slurry conducted from a slurry path is ejected from the excavating head 8 to the direction N as shown by the arrow and also from the nozzle of agitation blade 9 in the excavation process of the head 8. The solidifying slurry penetrates in the outside of the excavation wall face 14 and gets solid by the ejection of solidifying slurry from the nozzle of the agitation blade 9 in the rising process of the excavation shaft while adversely rotating after it has reached a specified depth. The columns 13 formed in this way has a larger diameter than the diameter at the excavating position cut by the excavation head 8.  By the construction of the columns 13, the space between the columns 11 is occupied by the columns 13 and hence, columns are constructed without space between them.

IPC: H04Q11/04
Filed: 1987-12-08
Abstract: PURPOSE:To prevent the scale of a circuit from being increased by providing a clock signal generating part to operate a synchronizing part, a recovery part, and an equalizer for waveform shaping provided in a device. CONSTITUTION:The synchronization of each asynchronous external line signal is performed by providing the synchronizing means 2 at the front stage of a line switching part 1. Also, by providing the recovery part 3 at the rear stage of the line switching part 1, the output of the line switching part 1 is recovered to an original signal corresponding to a synchronizing method at the synchronizing part 2. At this time, a clock signal to operate the synchronizing part 2, the recovery part 3, and the equalizer 4 for waveform shaping provided in the device is supplied from the clock signal generating part 5, and its frequency and phase are controlled. Therefore, even in case of providing the equalizer 4 for waveform shaping in multiple stages in the line switching part 1 according to the increase of the transmission speed of a signal, it is not required to extract the clock signal for the waveform shaping in each equalizer. In such a way, it is possible to prevent the scale of the circuit from being increased.
