Patent JP-S62125415-A (JP)
Title: Constant current driver
Inventor: YAMAMURO MIKIO
IPC: H02J1/00
Filed: 1985-11-26
Abstract: PURPOSE:To obtain a constant current drive circuit which has the stable actuation to the load whose impedance considerably changes, by increasing the maximum amplitude of the load application voltage without increasing the power supply voltage. CONSTITUTION:When the input voltage V0 is applied to the non-inverse input terminal of an operational amplifier OP1 via a resistance R5, the output voltage accordant with the level of the voltage V0 is outputted from the OP1 and applied to the load ZL via a sensing resistance RSC. An operational amplifier OP2 functions as an inverse amplifier and therefore the voltage having the adverse phase to the output voltage of the OP1 emerges at the output terminal of the OP2 and is applied to the other terminal of the load ZL. The load current changes owing to the change of the impedance of the load ZL and this current change is detected by the resistance RSC. The result of this detection is fed back via a resistance R7 and therefore the load current is kept at a constant level.

Filed: 1990-10-03
Abstract: PURPOSE:To shorten a job time by setting and storing in advance the transmission mode such as line density and density, reading a picture of each original in response to the transmission mode and sending the read picture information as a facsimile signal. CONSTITUTION:A 'department code', a 'page number' of an original entered from an operation section 1 are stored in a RAM 6 and the transmission mode of each original is stored in a bit map of the RAM 6 similarly as an attribute of each page. When the transmission start is commanded, a destination facsimile equipment is dialed via a network control unit(NCU) 9 and after the preparation of facsimile communication is ready, pictures of plural originals set to a scanner 2 are read in response to the transmission mode of the original stored in the RAM 6, the picture data is compressed by a data compression reproduction section(DCR) 7, modulated by a MODEM 8 and sent through the NCU 9.

Title: Printer
Inventor: IKEZOE YOSHIAKI
IPC: B41J2/485
Filed: 1989-10-11
Abstract: PURPOSE:To eliminate a need to give drawing data of a common part of contents again at the time of printing a document having the same common part as a document already printed once by using a storage medium to preserve and change given drawing data. CONSTITUTION:A higher-order interface part 1 communicates with a higher- order device, and a drawing data generating part 2 expands received drawing data on a drawing memory 3, and drawing data is changed by arithmetic processing. A drawing data compressing part 4 reads out and compresses drawing data in the drawing memory 3, and a memory card interface part 5 writes and reads out code data in and from a memory card 6. When drawing data is given, this data is written and preserved in the storage medium 6 by a control means 10; and when a change position is indicated by the higher-order device thereafter, the control means 10 changes the indicated position of preserved drawing data but does not change the other part to print data by a printing part 8. Thus, it is unnecessary to give drawing data of the common part of contents to the printer again.

Title: Ghost eliminating device
Inventor: ITO SHIGEHIRO
IPC: H04N5/21
Filed: 1988-10-21
Abstract: PURPOSE:To stabilize and ensure the eliminating operation of waveform distortion such as a ghost by first eliminating a low frequency component unnecessary for ghost elimination, detecting the waveform distortion, and executing the eliminating operation. CONSTITUTION:A low frequency cutoff device 19 is inserted between a subtracter 34 and a weight setting circuit 12. Band restriction is executed for the detected waveform so as to attain controllable setting by the limited number of taps, and the stable eliminating operation is attained. That is, since the limited number of the taps cannot control the waveform distortion, the unnecessary low frequency component is eliminated from a waveform distortion signal with the use of the low frequency cutoff device 19, a reference level is defined, and the ghost eliminating operation is stabilized. Thus, the reference level can be surely fixed at zero, an ideal clamped condition is obtained, further, since the level does not react to the uncontrollable low frequency component, the eliminating operation of the waveform distortion such as the ghost can be stabilized and ensured.

Title: Phase locked loop circuit
Inventor: TAKEUCHI HIROSHI
IPC: H03L7/10
Filed: 1991-10-15
Abstract: PURPOSE:To reduce the synchronization time and to widen the frequency lock range by detecting a phase difference 3/2pi between an input signal and a VCO output signal and inverting the output of the VCO with a changeover device with 2<n> frequency divider. CONSTITUTION:An output 13 of a 2<n> frequency divider 11 and a 2<n-1> frequency division waveform 21 of a 2<n> frequency divider 11 are NORed by a NOR gate 23, then a level of an output waveform 22 goes to an H level only for a phase difference of 3/2pi-2pi. Furthermore, an edge of an output waveform 14 of a changeover device 6 is detected by using an input signal 12 and its inversion signal 18 and when outputs 16, 17 of D-FFs 8, 9 go to a H level, the phase difference reaches a point of 3/2pi. Moreover, the output signal 14 is inverted by a switching control signal 15 at the detection point of time of 3/2pi. Thus, a frequency of the output signal 19 of the VCO 4 is fed back in a direction of the decreased frequency and the output signals 13, 14 are synchronized and then the input signal 12 and the output signal 19 are synchronized. As a result, the synchronizing time is reduced and the frequency lock range is made large.
