Inventor: ARAI MASAYUKI
IPC: G11B11/105
Filed: 1995-06-28
Abstract: PURPOSE: To record data with a much higher density by recording minute position information on the edge of a recording mark formed on a magneto-optical disk and recording the information of multistage external recording magnetic field in the recording mark itself. CONSTITUTION: Fundamental clock pits are beforehand recorded on a magneto- optical disk 1 which is rotated with a normal number of revolution by a spindle motor 13. A pickup 14 is controlled by a servo circuit 15 at the prescribed position on the disk 1 so that data 4 are recorded and reproduced. An external magnetic field generating coil 16 is provided on the opposite side of the disk 1 to record data. The laser light beam irradiation from the pickup 14 is controlled to a prescribed strength by a laser power controlling circuit 17. The pickup 14 irradiates the specific recording position of the disk 1 with the laser light beam and the data are recorded by irradiating a constant radius spot having a prescribed strength necessary for a thermomagnetic recording.

Title: Reset calling method
Inventor: ODAWARA TAKESHI
IPC: H04M3/42
Filed: 1989-07-19
Abstract: PURPOSE:To attain reset call with a simple operation even in the case of a line wire origination whose digit number is not ascertained as well as in the case of an extension call whose digit number is ascertained by providing a reset call button on a key telephone set. CONSTITUTION:When the user of the key telephone set 2 uses a telephone number of, e.g. 0-03-111-1234 to be originated with a line wire, a CPU 6 detects it via an extension circuit LC 4 to control a trunk TRK to implement the line wire dialing. When the opposite party of the line wire desires to change the telephone number into 03-111-1235 because of the busy state, the user depresses a reset call button 7 at first and then the number 5 is dialed. When the CPU 6 detects it via an LC 4, the number 4 of the final digit of the dial sent precedingly is deleted and the dial 5 is added instead, the line wire is hooked and the full dial of 03-111-1235 after the revision is controlled to be sent from a TRK 5. Thus, even in the case of the line wire dialing whose digit number is not ascertained, the reset call is attained with a simple operation.

IPC: H04L69/40
Filed: 1993-07-29
Abstract: PURPOSE:To take a countermeasure quickly and properly by detecting immediately unconnection of an opposite communication equipment or fault occurrence or the like. CONSTITUTION:When a transmission line is at a high level and a transmission line B' is at a low level, a receiver 2B1 of a communication equipment B sets an output signal 100 to a high level and when the line A is at a low level and the line is at a high level, the receiver 2B1 sets the signal to a low level. Since the input of a receiver 2B2 is connected to the transmission lines opposite to the input of the receiver 2B1 and the output signal 100 of the receiver 2B1 and an output signal 200 of the receiver 2B1 are opposite in the polarity to each other when the communication equipment A is operated normally, an output 300 of an AND circuit 3 is always at a low level to indicate it that the communication equipment is operated normally. However, when the communication equipment A is not connected or faulty, a fail safe function is acted on the receivers 2B1, 2B2 to set both the output signals 100, 200 to a high level. Thus, the output signal 300 of the AND circuit 3 is set to a high level and unconnection or a failure of the communication equipment A is immediately informed to the operator.

IPC: B41J15/04
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To sustain the humidity in a paper feed magazine constantly within a predetermined range. SOLUTION: A moisture conditioned paper 30 is set in a mounting tray 4 and subjected to pretreatment by leaving the moisture conditioned paper 30 in the environment of standard humidity, i.e., 60% RH, of a color thermal recording paper 11 for 4 hours or longer.
