Title: Digital multiplying and cumulative adding device
Inventor: ISHIZAWA YOSHIYUKI
IPC: G06F17/16
Filed: 1983-04-19
Abstract: PURPOSE:To speed up operation and reduce the scale of a circuit by providing two registers wherein one of partial addition results of a multiplying process and a cumulative addition result are accumulated, and allowing a common adder to perform those two kinds of arithmetic. CONSTITUTION:The 1st digital signal sequence X as a multiplier and the 2nd digital signal sequence Y as a multiplicand are inputted. The signal sequence X is divided into a 16-bit high-order part data A and a low-order part data B, and the sequence Y is also divided into data C and D similarly. The 1st multiplier 11 calculates P1=BXC, the 2nd multiplier calculates P2=AXD, and the 3rd multiplier calculates P3=BXC. In this case, while multiplexers 21 and 22 are switched from PA and PB to sides of registers 24 and 25, the 1st adder 15 enters the next adding operation, so the multipliers 11-13 also enter the next multiplying operations, thereby shortening the multiplication period.

Title: Multichannel carrier wave generator
Inventor: JII HOEI RIYAO
IPC: H03B25/00
Filed: 1993-03-26
Abstract: PURPOSE: To provide a multi-channel carrier generator which is easy to produce and has a low cost and obtains a stable carrier of less phase noise by branching a reference frequency to two routes and generating odd harmonics in one route and generating even harmonic in the other. CONSTITUTION: A power distributor 2 branches a reference frequency source to two routes. An input matching diode circuit 11 has an input matching circuit 111 and an anti-parallel connection diode 112, and multiple uniform odd harmonics are generated. A multi-power distributor 12 uniformly distributes odd harmonies generated in the circuit 11. A multiplex communication line filter 13 individually takes out odd harmonics generated in the circuit 11. Meanwhile, a frequency 2multiplier 21 doubles the reference frequency, and an input matching diode circuit 22 has an input matching circuit 221 and a diode 222 and generates multiple uniform even harmonics. A multiplex communication line filter 23 individually distribute uniformly harmonics generated in the circuit 22, and a multiplex communication line filter 24 individually takes out even harmonics. As the result, the frequency allowable deviation is large and production is easy because odd and even harmonics are generated independently of each other.

Title: Driver for brushless motor
Inventor: TANAKA MASAHIRO
IPC: H02P6/18
Filed: 1992-02-17
Abstract: PURPOSE:To provide a driver for brushless motor employing a starting system for making a switch from synchronous operation to position detecting operation in which ultra low speed operation can be realized by making a switch again to the synchronous operation if ultra low speed operation takes place during position detecting operation. CONSTITUTION:At the time of starting a motor, synchronous operation is performed until a voltage induced in an armature winding 4 exceeds a predetermined level and a position detecting operation is performed based on a position detection signal of a rotor 5 when the voltage induced in the armature winding 4 exceeds the predetermined level. If ultra low speed operation takes place during the position detecting operation, switching is made again to synchronous operation. If the phase of voltage to be applied on the motor immediately after switching is lagged, stability can be enhanced at the time of switching.

Abstract: PURPOSE: To perform inexpensive and clean electric discharge treatment by covering the non-treating side surface of a rotating base plate with a grounded shielding member rotating by leaving a spacing therefrom and further covering the outer side thereof with a grounded immobile shielding member.  
     CONSTITUTION: A base plate 2 mounted with works (a) is rotated together with a shielding member 6 behind the same in a vacuum treating vessel 1. When electricity is conducted from an electric supply 4 to the plate 2 through a condenser coupling 3, a potential difference is generated between the same and the electrode, not shown, provided in the vessel 1. The ions generated in accordance with this are made incident to the works (a) thereby etching their surfaces. Here, the immobile 2nd shielding member 10 having good grounding continuous to the ground 8 is provided via a fixing part 11 on the outer side of the rotating member 6. Therefore, the increasing of the potential difference between the plate 2 and the member 6 up to discharge potential is prevented in spite of the case when the member 6 is grounded by a mechanical contact means 7 of relatively poor grounding.

Title: Multilayer welding method
Inventor: NAKADA YOJI
IPC: B23K9/12
Filed: 1985-04-01
Abstract: PURPOSE:To obtain the work of high quality having excellent strength and sppearance by subjecting the butt part or overlapped part of welding beads to multilayer welding by sliding the position on each layer. CONSTITUTION:The distance up to the relay reference point C is determined to the welding length shift quantity on the initial first layer of either welding equipment 1 and 2 and the welding equipment 1 of one part reduces it slowly with the difference of the fixed length on each change of the layer. The welding equipment 2 of other part increases slowly reversely and it is decided so that the sum of both shifting quantities is coincided with the total length of the weld line 2 on each layer. The seam part of the weld line 3 thus becomes abutted seam and the upper the layer becomes with the slipping off of this abutted position among each layer, the more it becomes apart from the relay reference point C.

Filed: 1992-02-19
Abstract: PURPOSE:To reduce residual amplitude modulation noise and phase modulation noise by inputting a phase inverting signal based on a ripple component to an amplitude modulator and a phase modulator connecting to a high frequency amplifier so as to cancel the residual amplitude modulation noise and phase modulation noise. CONSTITUTION:A ripple extract phase inverting circuit 6 receives a voltage division signal Vr of a helix voltage and extracts a ripple component other than a DC component included in the signal Vr to invert the phase by 180 deg.. Moreover, bias circuits 7,8 receive an inverting ripple signal from the circuit 6 to apply a modulation signal respectively to an amplitude modulator 4 or a phase modulator 5. Then a travelling wave tube 2 generating a residual AM noise and phase noise by a ripple component mainly included in the helix voltage is considered to be an amplitude modulator and a phase modulator regardless of a small modulation figure. The amplitude modulator 4 and the phase modulator 5 provided to a pre-stage of a high frequency amplifier 1 use the signal resulting from phase-inverting the ripple component extracted from a power supply section 3 for a modulation signal thereby cancelling amplitude and phase modulation caused by the modulation action of the travelling wave tube 2.

Abstract: PURPOSE:To simplify a separator for stacked works in structure, by installing a guide member, which rocks a claw member so as to make its claw separate from the work in a down process and to restore it to a support part of the work, and a work receiver receiving the work both. CONSTITUTION:A crank 28 starts its rotation from a bottom dead center to a top dead center and a lifting member 18 makes a claw member 19 go upward. At this time, the claw member 19 rocks in a direction where a claw 19 comes nearer to a tray 2 as going up in an opposite state to the preceding latter half of down, by guidance at an inclined guide surface, and it is returned to a support part of the tray 2 one step above the tray 2 supported by a work receiver 23. The claw member 19 supports remaining stacked trays 2 and goes up in a state of separating the lowermost tray 2 from the work receiver 23. When a crank 28 gets closer to the vicinity of the top dead center, a rotary actuator 21 is stopped by operation of a top dead center detecting sensor 39 whereby the claw member 19 keeps such a state that supports the remaining stacked tray 2. During the while, the tray 2 separated from the work receiver 23 is fed to a tray line 5.
