Title: Starting system for sensorless motor
Inventor: KANEDA ISAO
IPC: H02P6/06
Filed: 1989-11-30
Abstract: PURPOSE:To simplify the structure of a motor by a method wherein the condition of an exciting coil is detected from energy, stored in a plurality of exciting coils during restricting period of time, as an electric characteristic and a rotor is rotated into a predetermined direction during successive starting period. CONSTITUTION:When a power source is thrown, a conduction switching circuit 23 puts transistors Q1-Q6 ON/OFF to conduct phase currents I-Iw by a phase switching circuit 25 whereby energy is stored in coils Lu-Lw. After a predetermined time, the conduction switching circuit 23 nullifies the conduction and discharges the energy whereby capacitors C1-C3 are charged by both terminal voltages of resistors R1-R3. The charge of the capacitors C1-C3 becomes values affected by the effective inductances of respective coils while the outputs of comparators CP1-CP3 detect the direction of rotation through detectors 29 to indicate them in a phase switching circuit 25. When the restricting period is finished, the motor is started and accelerated whereby the rotation of the motor is shifted into a rated rotation.

Filed: 1988-12-12
Abstract: PURPOSE:To expand a service area optionally without reconstructing a fixed network only by installing a base station device optionally and independently by determining whether the communication of a mobile equipment is allowed or not and its charging processing by using a credit communication function provided originally to the fixed network. CONSTITUTION:Only when a registered subscriber number and a password number which are sent from the mobile equipment 4 match one of combinations of subscriber numbers and password numbers stored in a device 10, the communication from the mobile equipment 4 is connected to an opposite party requested by the mobile equipment 4. Then the charge for communication is integrated by the device 10 corresponding to the registered subscriber numbers. Thus, the credit communication function of the fixed network is utilized, so the service area can be expanded optionally without reconstructing the fixed network side nor installing a communication line between base stations only by connecting base station devices 2, 3, 6-8 to the subscriber line 6 of the fixed network.

Title: Magneto-optical signal reproducing device
Inventor: TANAKA HIROAKI
IPC: G11B20/10
Filed: 1992-11-20
Abstract: PURPOSE:To provide the magneto-optical signal reproducing device suitable for making into an IC by preventing the saturation of an amplifier and enlarging a feedback resistance value by extracting only the regenerative signal by erasing a spurious signal component from an electric signal converted by a photoelectric converter by using an arithmetic unit. CONSTITUTION:Signal line PSIG+DC is converted to a signal light current ISIG+DC by a photoelectric converter 1 composed of a PIN photodiode PD. Although this current ISIG+DC flows to a transistor TRQ1, a first current mirror circuit is composed of TRQ1 and Q2 so that the current ISIG+DC equal to the current flowing to the TRQ1 can flows to the side of the TRQ2 as well. The current to flow to the side of this TRQ2 is turned to a DC component IDC after a regenerative signal component ISIG is removed by an integration capacitor C0. Next, although the current IDC flows to a TRQ3, a second current mirror circuit is composed of TRQ3 and Q4 as well so that the current IDC equal to the current flowing to the TRQ3 can flow to the side of the TRQ4 as well. Therefore, the IDC is subtracted from the optical current of the PIN diode PD, and only the regenerative component ISIG is provided.

Filed: 1994-11-22
Abstract: PURPOSE: To provide the data communication system for communication terminal using a mobile communication equipment where a system itself is inexpensively constituted by enabling a communication terminal for general telephone line to communicate data with the mobile communication equipment with the same procedures as transmission through a general telephone line and automatically adding a toll number in the case of a lack of the toll number. CONSTITUTION: When a DTMF signal or a dial pulse signal is sent from a personal computer with a MODEM, a DTMF decoder 8 or a voltage detector 7 decodes it to send the telephone number to a control circuit 11. If a toll number is not added, the toll number is added by the control circuit 11 to originate a call. When it is detected that the call is originated by the DTMF signal or the dial pulse signal, an f characteristic switching circuit 6 is switched, and the high-band characteristic is raised more than that for voice to keep the quality of data transmission. When the line is connected, data communication is started, and it is cleared by on-hook information on the personal computer side.

Title: Plasma torch
Inventor: SAKURAGI SHUNICHI
IPC: B23K10/00
Filed: 1993-11-19
Abstract: PURPOSE:To obtain a plasma torch which is long in life of a nozzle, etc., and is less bonded with dross by installing the nozzle side at the front end of the torch near the bottom end face of an electrode with a speed relieving space for decreasing the axial velocity components of a working gas. CONSTITUTION:The working gas turns to a tangential swirler by passing a swirler member 7 from a supply gas passage 11 and flows into a gas passage 13, thus forming uniform swirling gaseous flow. Further, the swirling gaseous flow accelerated by entering an acceleration space M from an approach section L flows into the speed relieving space N installed near the bottom end face 3b of the electrode. The arc column in the torch is stably maintained at the axial center of the electrode by using a low pressure in the central part of the swirl formed by the swirling gaseous flow in the speed relieving space N. Since the diameter Dd of the speed relieving space N is large, the distance between the outer edge of the arc column and the wall of the speed relieving space N increases and the thickness of a gas insulating layer increases to suppress generation of double arcs. The working gas is throttled to make the arc column finer in the next acceleration space P. Such arc is passed to a nozzle restricting part 9a, by which the prescribed plasma arc is formed.

Abstract: PURPOSE:To keep toner concentration precise for every developing device even when a developing device is replaced by comparing an output detected by the toner concentration sensor of the developing device loaded to an image forming device and a value stored in a non-volatile memory at the time of image formation and controlling the toner concentration of developer. CONSTITUTION:First, the reference toner concentration of developer is detected by the toner concentration sensor (inductance sensor) 34 and written in the nonvolatile memory 37. Then, at the time of the image formation, the toner concentration of the developer is controlled by comparing the output detected by the toner concentration sensor 34 of the developing device 7 loaded to the image forming device and the value stored in the nonvolatile memory 37. In other words, the toner concentration is controlled to equalize the reference value. Thus, the toner concentration can be kept precise even when the developing device 7 which possesses different types of colored toner is replaced and used.
