Title: Logic circuit using norton amplifier
Inventor: TACHIKAWA YASUO
IPC: H03K19/02
Filed: 1984-08-29
Abstract: PURPOSE:To improve the noise margin and to reduce the number of components by constituting a logic circuit with a Norton amplifier inputting the total sum of currents from plural input terminals and a prescribed bias current at respective terminals. CONSTITUTION:When logical voltage signals 33-36 are fed to logical input terminals 29-32, a total sum current 45 of currents 41-44 limited respectively by resistors 37-40 flows to a positive current input terminal 50 of a Norton amplifier 49. A bias current 48 formed by a bias voltage 46 and a bias resistor 47 flows to a negative current input terminal 51 of the amplifier 49. The amplifier 50 amplifies the current difference of both currents 45 and 48, and when the current 45 is larger than the current 48, a logical voltage signal 52 at an output terminal 53 goes to H level and when the current 45 is smaller tan the current 48 conversely, the signal 52 goes to L level. AND/OR/AND-OR operations are attained with the same circuit constitution by changing the ratio of the input resistors 37-40 to the bias resistor 47.

Title: Method for developing electrostatic charge image
Inventor: KASUYA RIYUUHEI
IPC: G03G9/08
Filed: 1982-10-12
Abstract: PURPOSE:To improve the developing property, carrying property, and transferring property of a developing agent, by making the developing agent from an insulating magnetic toner and surface-coated magnetic particles having diameters which are smaller that those of the toner. CONSTITUTION:A developing agent 2 is composed of an insulating magnetic toner prepared in such a way that a magnetic material is dispersed in a resin and, as occasion demands, a coloring material, etc., is incorporated in the resin, and an auxiliary agent of surface-coated insulating magnetic particles prepared in such a way that their surface sliding resistance, coated thickness, electric resistance, and particle shape are most suitably selected in accordance with the developing method by the surface coating and their diameters are made smaller than those of toner so as to maximize their specific surface area. When such a developing agent is used, the sliding property of the agent between particles is improved and, therefore, response to the direction displacement of the magnetic force is made quicker and the fluidity and frictional frequency by charging of the developing agent are improved. Therefore, the developing property, carrying property, and transferring property can be improved.

Title: Buffer memory control circuit
Inventor: TAKEUCHI KOJI
IPC: G06F5/06
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To avoid a retrial operation in data transfer. SOLUTION: A retrial recognition circuit 13 stores the volume of transfer data from the start of data transfer up to the reception of a retrial request from a memory controller 6 and recognizes the capacity of an FIFO 7 in the controller 6. When a data transfer volume control circuit 3 is informed of the stored transfer data volume from the circuit 13, the circuit makes 3 the capacity of an incorporated I/O card FIFO 3 match with the capacity of the FIFO 7 on the basis of the transfer data volume. Since the capacity of the FIFO 7 is matched with that of the I/O card FIFO 3, retrial does not occur. A PCI bus e.g. not regulating the capacity of the FIFO 7 is also used as an internal bus 5.

IPC: G06Q30/06
Filed: 1984-08-30
Abstract: PURPOSE:To make power source for preserving data unnecessary, to turn off power source after a dinner time ends and to remove necessity to assure power source for a long time against power failure by backing up the data with a non-volatile memory. CONSTITUTION:Data from external input devices 1, 2 ... are stored through an input control part 11 through CPU 12 to RAM 13. The data are processed at CPU 12 and stored in a floppy 16 and written in a non-volatile memory 17 by using an empty time. In a memory 17, an electrical erasable programmable ROM, a bubble memory, a magnetic tape, etc., are used. A power supply (non- power failure unit) 19, after a power source 18 is turned of, assures power source of the circuit only for a short time necessary to write the data not written in the non-volatile memory 17 from RAM 13 to the memory 17 completely. Consequently, simultaneously when RAM is used, it is not necessary to back up a battery for a long time.

Title: Transmitting gate circuit of time-division multiple access communication system
Inventor: TAKAHARA SHIGERU
IPC: H04J3/10
Filed: 1981-11-09
Abstract: PURPOSE:To reduce interference with other communication without using any high-speed variable attenuator with high performance by equipping a base band stage with an amplitude modulator which inputs the control signal of an attenuator, and driving a main modulator by its output signal. CONSTITUTION:For TDMA communication, the output of a carrier oscillator 1 is supplied to an orthogonal modulator 2, whose output is sent out from a variable attenuator 3. A base band input 11 is applied to the modulation input of the modulator 2 through an amplitude modulator and amplifier 4 and an LPF5. According to the voltage polarity of the modulated input signal, the modulator 2 has its output carrier varying in phase from 0 deg. to 180 deg.. To obtain a burstlike signal, the attenuator 3 has two states of low attenuation and high attenuation according to a control signal 12, but the amplifier 4 has a large output amplitude during burstlike signal transmission and output amplitude of almost 0 at other time under the control of the signal 12, so the attenuator 3 reduces interference with other communication without providing with high performances.

Title: Information processor
Inventor: NAKAMURA AKIYOSHI
IPC: G06F13/38
Filed: 1989-07-12
Abstract: PURPOSE:To attain a quick switching operation and to omit an RS232C interface part formed in a MODEM for reduction of the power consumption and the weight of an information processor by using a switch means to perform the switch to an interface primary part of the RS232C between a MODEM primary part contained in the information processor and an RS232C input/output part. CONSTITUTION:An RS232C interface is divided into a primary part 12 and an input/output part 14, and a switch means 13 is set between both parts 12 and 14 to perform the switch between a MODEM and an RS232C input/output part. A primary part 15 obtained by excluding the RS232C interface part from the MODEM is directly connected to the part 12 via the means 13. Thus the switch is attained between the RS232C and the MODEM via an internal switch circuit of a computer without changing the conventional software. As a result, the switch can be instantaneously carried out and at the same time the RS232C interface circuit can be omitted in the MODEM. Then the power consumption and the weight can be reduced for an information processor.
