Title: Permanent magnet erasing head
Inventor: HASEGAWA KYOICHI
IPC: G11B5/325
Filed: 1985-11-29
Abstract: PURPOSE:To obtain an erasing characteristic of a good S/N by alternately forming N, S regions and adjacent N, S regions of strontium ferrite and Mn-Zn ferrite on the working surface of an erasing head and further constituting the head in such a manner that the working face is single-pole magnetized to gradually decrease the intensity of the magnetic field. CONSTITUTION:The erasing head is dispersed with the strontium ferrite 1 and the Mn-Zn ferrite 2 on the surface for sliding with a magnetic head so as to be made alternate with and adjacent to each other and is further constituted to the subjected to gradually decreasing single pole magnetization to increase the magnetization intensi ty on the inlet side of the tape and to decrease on the outlet side. The number of alternating magnetic poles is thereby increased and the residual magnetization after erasing is approximated to a magnetic neutral point. The S/N is made higher than the S/N ratio of the conventional head and further the width of the magnetic tape is made multipolar as well. The magnetic fluxes picked up in the gap of a reproduction head in the stage of reproduction are reverse from each other in components and negate each other even if the magnetization pattern thereof the transferred to the magnetic tape. The detachment noise of the head by the transfer pattern is thereby decreased.

Filed: 1991-10-18
Abstract: PURPOSE:To improve printing quality of a color image by providing an interlock release mechanism releasing a driving motor and a dust ejection mechanism during execution of an image transfer in a shared driving mechanism. CONSTITUTION:A photosensitive drum 2 is rotated and driven in a state where a screw 17 is stopped by having a one way clutch 25 moved interlocked with a forward rotation of the driving motor 23 while another one way clutch 26 is run idly. When completion of image transferring is detected by detecting the number of revolution of the driving motor 23 or ejected printing paper 15, etc., the forward rotation of the drive motor 23 is changed over to a reverse rotation and the motor is driven for a specified time. When the driving motor 23 is rotated in reverse, since a photosensitive drum 2 is stopped and a screw 17 is driven by having one of the one way clutches 25 and 26 run idly while the other is moved interlocked, the dust deposited in a drum cleaner 3 due to the image transferring is carried to a dust container.

Abstract: PURPOSE:To raise the resolution of a binary image by outputting a data which represents the maximum value or the minimum value when a deviation between a gradation data corresponding to a remarked small area and the gradation data corresponding to the small area adjacent to the above area is out of a set range. CONSTITUTION:Against a gradation data D corresponding to the remarked small area outputted from a one line buffer 5, the data D itself is inputted to a control buffer 121, and a data 2D+1 to a binary full adder (ADD) 8.

Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To eliminate necessity to unlock data demodulation finger for tracing a synchronous channel or to capture the synchronous channel again by matching a combiner with the first data demodulation finger, acquiring the pseudo random (PN) offset of a code division multiple access(CDMA) base station and updating a PN mask table with that off set. SOLUTION: While a lock detection logic part stays in a lock state on a pilot channel, a CPU 23 regards a received signal as the value of PN offset equal to zero, sends a command and initializes the combiner. A prescribed procedure is executed continuously to the rising point of 26.6 ms of the data demodulation finger unit. After PH offset data are acquired from the synchronous channel, the CPU 23 updates the PN offset register of a searcher unit and the PH offset register of the demodulation finger unit and updates an internal data table 25 called PN master table.

Abstract: PROBLEM TO BE SOLVED: To obtain an energy-saving function by placing a local area network communication means and a device main body in an energy-saving mode when a specific time has elapsed in standby mode and resetting the energy-saving mode when a specific event occurs. SOLUTION: When an energy-saving key of an operation display part 7 is operated or when the standby mode continues for a period longer than the specific time, network facsimile equipment FX outputs a signal SC1 from a system control part 1 to an energy-saving control part 13 to inform a local area network LU of the energy-saving mode transition and the energy-saving mode is entered. Electronic mail acquiring operation is carried out even in the energy-saving mode and when an electronic mail is received, a CPU 21 outputs a return instruction signal SSt to the energy-saving control part 13. The input of the return instruction signal SSt is handled as an energy-saving mode reset event.  If various events occur in the energy-saving mode, the energy- saving control part 13 turns on a main power source PA2 and outputs a signal SC2 giving a notice of the energy-saving resetting factor to the system control part 1.

Title: Light signal transmitter
Inventor: SHIKADA MINORU
IPC: H04B10/572
Filed: 1987-10-27
Abstract: PURPOSE:To maintain the peak value of light signal pulses and light dc output at respective predetermined values and suppress chopping modulation as well, by monitoring the output light level of a light semiconductor element with a light sensor and further, causing the output of a minimum value detecting circuit to perform its feedback to a bias current source, thereby causing the output of maximum value detecting circuit to perform its feedback to a drive circuit. CONSTITUTION:When a semiconductor laser 1 is driven by a pulse drive circuit 2 and a bias current source 3, a light output pulse 4 from one-sided surface of a resonator is inputted in a light sensor 5 and waveforms are monitored. After being amplified, a monitor output 6 is inputted in maximum and minimum value detecting circuits 8 and 9 of the waveforms. The maximum value detecting circuit 8 detects a peak level of waveforms of the monitor output 6. The detection circuit 9 reads the light output level at the place of a bias current level. These outputs at the detecting circuits 8 and 9 are compared by a differential amplification circuit 10 and its output corresponds to the peak value of pulses. Thus, the pulse peak value and the dc light level of the light output are suppressed to respective predetermined values by allowing the outputs of the detecting circuit 9 and the amplification circuit 10 to perform their feedbacks as respective control signals of the current source 3 and the pulse drive circuit 2.

IPC: H01L21/76
Filed: 1987-10-27
Abstract: PURPOSE:To control the junction leak of an inverter transistor as well as the narrow channel effect of an access transistor by implanting boron for channel cut into a groove for inverter transistor isolation more than into a groove for access transistor isolation. CONSTITUTION:A semiconductor storage device is made by isolating each of transistors 1-4 included in a memory cell by an element isolation groove 22 and boron for channel cut is implanted more into a groove for inverter transistors 3, 4 isolation than into a groove for access transistors 1, 2 isolation. Since more boron is thus implanted into the groove for inverter transistor isolation than into the groove for access transistor isolation, the junction leak at an inverter transistor is reduced and yet the narrow channel effect at an access transistor is controlled. As a result, MOS static RAM(SRAM) of high resistance load type can be provided with high density without increasing its standby current.
