Title: Drive unit of brushless motor and positioning table using this
Inventor: MAKITA YOSHINORI
IPC: H02P7/00
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To minimize the thrust drop in the vicinity of phase switching position of a brushless motor, by providing a power detection means which detects the thrust or torque generated by a motor and a negative feedback means which negatively feeds back the thrust or torque signals from the power detection means into a drive command signal. SOLUTION: This device is equipped with a thrust detector or a torque detector 13 which detects the thrust or torgue that the motor generates, at the motor coupling part on the side of a stator 2 or a rotor 3 of a brushless motor. Then, this is provided with a negative feedback means 14 which negatively feeds back the thrust or torque signals from the thrust detector or torque detector into a drive command value. Hereby, it becomes possible to compensate the thrust ripple or torque ripple that the motor has. Accordingly, a positioning table device high in positioning accuracy, short in positioning time and small in speed irregularity can be obtained by using the drive unit of the motor.

Title: Carburetor for internal combustion engine
Inventor: TAMAI KATSUYUKI
IPC: F02M17/40
Filed: 1982-08-13
Abstract: PURPOSE:To prevent both carburetor cooling due to heat of vaporization and a vapor lock by connecting a plastic carburetor to an engine via both a material of small thermal conductivity and a heat insulator. CONSTITUTION:A carburetor 14 is made of a hard plastic material and connected to an engine 20 via a cylindrical insulator 18 made of a plastic material. A conductor 34 is made of aluminum alloy whose thermal conductivity is greater than that of plastic material for the carburetor main body 14.

Title: Discharge lamp checker
Inventor: INOUE AKIHIRO
IPC: G01R31/24
Filed: 1978-11-15
Abstract: PURPOSE: To enable the quantitative estimation of the exhausted state of a discharge lamp with a small and light circuit by checking the lighting of the discharge lamp with the variable oscillation voltage of a high frequency oscillation circuit.  
     CONSTITUTION: Commercial AC voltage is changed with the slider 7a of a slider auto-transformer 7, rectified by a rectifying circuit 9 and applied to the collector of a transistor 10 via a high frequency choke coil 11. The base of this transistor 10 is connected with a parallel high frequency oscillation circuit consisting of an oscillation coil 12 and condensers 13W15, and oscillation voltage is proportionate to a DC current which flows between the collector and the emitter of the transistor 10. Therefore, by exciting a discharge lamp with high frequency oscillation output and reading the scale of the revolving knob of the slider 7a at the time of lighting calibrated with the oscillation voltage, the exhausted state of the discharge lamp can be estimated quantitatively with a simple and small configuration.

IPC: G06F15/18
Filed: 1994-06-22
Abstract: PURPOSE:To attain stable and quick learning by learning only an initial state until the reduction of errors becomes less than a threshold in the case of extending a learning section in a past direction and learning it again, and then learning a weight value and a time constant also. CONSTITUTION:At the time of judging that a learning section is extended in a time-retroactive direction, a learning section control part 41 outputs a control signal to a learning control part 54 and the control part 54 receiving the signal outputs a control signal to a most nose diving direction calculating part 47, a network parameter correction quantity calculating part 48 and a network parameter correcting part 49. Immediately after extending the learning section in the time-retroactive direction, a convergence deciding part 46 decides an error at each time sent from a reverse propagation error calculating part 45 and the control part 41 learns only the initial state by the use of the extended time-sequential data without updating an already learned weight value and a time constant until the quantity of error reduction becomes less than a threshold. After its reduction less than the threshold, the control part 41 learns the weight value and the time constant in addition to the initial state.

Abstract: Several guide channels (6, 7) for respectively one paper web are arranged in a fan shape, these channels being oriented toward the nip (5) of a pair of feed rolls (1) of a printing device (2, 3) and each being equipped with a gripper (8, 9). In the rest position, each gripper (8, 9) is in contact with a web of paper, and the free ends of the paper webs have a spacing from the nip (5). The gripper (9) for the paper web to be printed advances the latter until it has entered the nip (5) of the rotating pair of rolls (1), then releases the web, and initially remains in its position (8). The pair of rolls (1) further conveys the paper web first into its printing position, after the printing step into its cutting position, and after cutting again in the reverse direction. Before the paper web leaves the nip (5), the gripper (8) engages once more and returns into its rest position (9), entraining the paper web, so that the end of the latter, produced by the cutting step, assumes the position occupied by its previous free end prior to the advancement of the grippers. In this way, it is possible to print in any desired sequence onto various paper webs and also directly in succession onto one and the same paper web.
