Title: Time division multiple access communication equipment
Inventor: FUJIKI KAZUYOSHI
IPC: H04W56/00
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To attain expansion of range by setting the delay time of a slot before or after the slot under communication over guard time when that slot is not used. SOLUTION: When communication is performed between a base station 10 and a terminal 13 in its ordinary area 11, the delay time is set corresponding to the distance but it is within the guard time as conventional techniques. When the terminal 13 tries to move out of the area 11 as shown by an arrow, in this case, the base station 10 monitors the condition of the slot before or after the slot for the communication of the terminal 13 and when that preceding or following slot is used, operation is performed as usual but when that preceding or following slot is not used, the setting value of delay time is set over the guard time so that communication can be continued.

Title: High speed equalizing method for digital magnetic recording current
Inventor: KATO TADASHI
IPC: G11B5/09
Filed: 1987-06-15
Abstract: PURPOSE:To attain high speed inversion of a recording current by utilizing a high through-rate at the leading of a recording current due to an excess current or a high through-rate of leading of recording current due to insufficient damping in addition to the former high through-rate. CONSTITUTION:A current i0=i1+i2 flowing to a head system is changed result ingly by using a control pulse so as to switch plural differential current switches 14, 17, 22, 25. Actually, in recording data, the current i0 is set to be an optimum recording current depending on the head receiving the current and the character istic of the medium. The high through-rate of the leading of current due to excess current of insufficient damping is utilized in this way, then the vibrating current component or excess current component caused at that time is canceled completely by selecting an equalizing parameter properly, and the proper rectan gular recording current waveform is obtained while the high through-rate at leading is being kept. Thus, the high recording current inverting speed is attained.

Filed: 1989-06-13
Abstract: PURPOSE:To obtain a toner compsn. having superior pressure fixability by incorporating a specified bifunctional amide monomer as a binder resin into a toner compsn. CONSTITUTION:A bifunctional amide monomer represented by a formula Y-R-Y (where Y is an amido group having at least one hydroxyl group as a substituent and R is a satd. or unsatd. cyclic group bonding Y's) is incorporated as a binder resin to obtain a toner compsn. having superior pressure fixability. Since at least two hydroxyl groups are present in one molecule of the amide monomer, chemical attraction to paper is increased and exfoliation at the interface between paper and a toner image can be suppressed. Exfoliation in a toner layer can also be suppressed because of the high aggregating power of the toner itself. Thus, the toner compsn. having superior pressure fixability.

Title: Toner concentration control method
Inventor: NAMEKATA SHINICHI
IPC: G03G15/00
Filed: 1990-06-08
Abstract: PURPOSE:To enable invariably stable and highly reliable toner concentration control by not setting an initial set value when a toner concentration target value is an upper-limit or lower-limit value at the time of the toner concentration control. CONSTITUTION:With a developer concentration signal obtained by detecting the toner concentration in a developing unit, the toner concentration is controlled to the target value between the specific upper-limit value and lower-limit value, and the target value is corrected with a pattern image density signal obtained by detecting the density of a reference pattern image formed on a photosensitive body. In this toner density control method, the pattern image density signal is generated by comparing the ratio of the detected value of the density of the reference pattern image and the detected value of the density of a ground part with the initial set value and when the target value is equal to the upper- limit or lower-limit value, setting operation for the initial set value is not performed. Consequently, abnormal image density due to improper initial value setting under the toner concentration control can be prevented.
