Patent JP-H10337041-A (JP)
Title: Inverter
Inventor: SAEKI KOJI
IPC: H02M7/06
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To provide an inveter in which high input power factor and low input current distortion factor can be attained while decreasing the number of elements and simplifying the control. SOLUTION: The inverter comprises a timer circuit 5 delivering a driving signal Ve for controlling the ON interval of the switching element Q1 in a chopper circuit 3. A signal generated from an inverter circuit 1 is delivered, as a synchronous trigger signal Vf, to the timer circuit 5 where the output timing of the driving signal Ve is determined using the synchronous trigger signal Vf. The synchronous trigger signal Vf is synchronized with a driving signal Vb from a control circuit 4. Since the switching elements Q2 , Q3 in the inverter circuit 1 and the switching element Q1 in a chopper circuit 3 can be subjected to interlocked control, the number of elements can be deceased and the circuitry of an on/off control system for the switching elements Q1 -Q3 in the inverter circuit 1 and the chopper circuit 3 can be simplified.

Title: Liquid fuel combustion device
Inventor: HANEDA TOMOHISA
IPC: F23D11/04
Filed: 1988-06-03
Abstract: PURPOSE:To prevent gasified fuel from counterflowing, and to realize stable gasification combustion while keeping liquid fuel within a liquid fuel supply pipe from being gasified, by providing a cylindrical support fittings for the liquid fuel supply pipe, which has, at its bottom part, an air outlet port and an insertion hole for the liquid fuel supply pipe, between an air feed port and a rotor for atomizing the fuel. CONSTITUTION:Since air flowed into a gasifying chamber 23 through an air feed port 21 is throttled at the air port 44 of a support fitting 42 to increase its flow speed, there is no possibility that gasified fuel in the gasifying chamber 23 counterflows to a blower side through the air outlet port 44 and the air feed port 21. Further, since a clearance is formed between the lower opening end of the cylindrical part 42A of the support fittings 42 and the bottom wall 23A of the gasifying chamber 23, the very small amount of heat is only transferred from a gasifying cylinder 22 to a liquid fuel supply pipe 41 through the mounted leg 42A of the support fittings 42, and accordingly there is no possibility that liquid fuel at the top end 41A of the liquid fuel supply pipe 41 is gasified. Furthermore, since such a clearance may be formed into small one, no gasified fuel leaks out through the clearance. In addition, a necessary consideration is taken into account such as to prevent the leakage of fuel by such means as to provide rising-up flanges 21A and 44A at the air feed port 21 and the air outlet port 44, respectively.

Title: Color noise evaluation method
Inventor: KOBAYASHI MASANORI
IPC: H04N9/85
Filed: 1988-06-07
Abstract: PURPOSE:To obtain a data corresponding to the visual evaluation of color noise on a reproduced screen in the quality check of a disk by detecting it as a color noise only when a luminance signal level or a color signal level is below a prescribed level at a point of time of production of color noise. CONSTITUTION:Color noise is detected by a color noise detection circuit 2 from a reproduced RF signal supplied from an input terminal 1 and fed to a gate circuit 9. On the other hand, after the reproduced RF signal is demodulated into a video signal by a demodulation circuit 3, a trap circuit 5 eliminates a color component and only a luminance component is extracted. The separated luminance signal is clamped by a clamp circuit 6 by means of H synchronizing signal (horizontal synchronizing signal) being an output signal of a sync separate circuit 4. The clamped luminance signal is compared with a reference value (e.g., 501RE) set by a constant, voltage generating circuit 8 at a comparator 7 and when the value is over the reference value, an output pulse is generated from the comparator 7 and fed to the gate of the gate circuit 9. The output signal of the color noise detection circuit 2 is passed through only in the absence of the output pulse of the comparator 7.

Abstract: PURPOSE:To automatically mount parts on a circuit board with a high precision by preparing a trouble area fundamental table and an interference condition table. CONSTITUTION:Terminals 2 of parts 1 are placed at grid points of a board 3 to prepare a mounting table of output information of CAD where positions, directions presence/absence of polarity of first terminals 21 and second terminals 22 diagonal to them of respective parts are arranged in the work order, a trouble area table of already mounted parts 1, and an interference condition table where interference areas between parts themselves and peripheral parts are vertically and horizontally corrected based on terminals 21 and 22 and are deter mined by numbers of grid pitches. When the N-th parts will be mounted, the mounting table is read out and corresponding information of the trouble area fundamental table is successively corrected with respect to already mounted parts to interference. When interference is not detected at all, mounting information is added to the trouble area fundamental table. When interference is detected, the mounting direction is inverted to perform check again if parts has no polarity and interference is eliminated to add the mounting condition to the trouble area fundamental table. When interference is detected again or parts have a polarity, auto matic mounting is impossible. By this constitution, three-dimensional movement interference is checked in two dimensions with a high precision.

According to the connection of the windings and the signals applied, the motor may step forward or backward, or in either sense at an accelerated speed. Such a motor is particularly suited to drive a timepiece movement.
