Title: Ion beam mass spectrograph
Inventor: KURODA KATSUHIRO
IPC: H01J37/317
Filed: 1983-03-16
Abstract: PURPOSE:To perform blanking of ion rays in a mass spectrograph, which is constituted by using two parallel nonmagnetic electrodes and two parallel nonmagnetic electrodes which are perpendicular to the former two electrodes, by changing the voltages of the electrodes so as to make it impossible for ion rays to pass through the hole of a throttle plate according to necessity. CONSTITUTION:Nonmagnetic electrodes 3 and 4 are placed parallel to the traveling direction (optical axis) of ion rays discharged from an ion source. Nonmagnetic electrodes 5 and 6 are placed perpendicular to the electrodes 3 and 4. A throttle plate 8 having a hole 7 on the optical axis of the ion rays, is placed perpendicular to the optical axis in the back of the electrodes 3, 4, 5 and 6. The electrodes 5 and 6 are permanent magnets. By directing a magnetic field (B) toward -x direction, lighter ion rays 1 are more greatly curved than heavy ion rays 2. By applying voltages V and -V to the electrodes 3 and 4 respectively, the ion rays 2 are deflected toward -y direction by means of an electric field (E) and only ion rays 1 passing through the hole 7 can be taken out. In addition, by applying voltage W to either the electrodes 5 or electrodes 6 and earthing the other electrodes, the ion rays 1 and 2 are respectively polarized in directions 1' and 2' and no ions pass through the hole 7 thereby enabling blanking to be performed.

Title: Waste ink treatment apparatus
Inventor: ITO YOSHIHIRO
IPC: B41J2/18
Filed: 1995-03-02
Abstract: PURPOSE: To achieve miniaturizing planning dispensing with a high capacity supply tube or a large capacity waste ink tank by arranging the holder of a waste ink cartridge at a fixed place other than a carriage to enable the replacement of the waste ink cartridge. CONSTITUTION: The waste ink cartridge holder 1-10 is arranged at a fixed place other than a carriage 1-4 moved accompanied by printing. A waste ink cartridge 11 recovers waste ink and, even when a printer is inclined, the ink does not simply leak to the outside. A waste ink cartridge 1-11 can be easily replaced by a user and two kinds of cartridges can be provided as a pair of sets and, since the capacity thereof can be reduced to that of an ink cartridge 1-6 or less, miniaturizing planning becomes possible. It becomes unnecessary to guide ink to a head by using a high capacity ink supply tube reduced in air permeability, good in bending properties and having length not obstructing the movement of the carriage.

Title: Filter frequency controller
Inventor: NISHIHARA NOBUHIDE
IPC: H03H11/04
Filed: 1988-02-24
Abstract: PURPOSE:To always keep the filter frequency of a resonance means to a prescribed value by shifting the phase of an input AC signal by means of the resonance means so as to generate two phase shift signals having a prescribed phase difference and controlling the phase difference of the phase shift signal so as to be always at a prescribed value. CONSTITUTION:A prescribed frequency band from a connecting point between a resistor R and a coil L in a signal from a 1st AC signal source 1 is filtered by a 1st resonance circuit 3 and two phase shift signals are outputted from output terminals A, B. The phase shift signals have a phase difference of nearly 90 deg. when the resonance frequency of the 1st resonance circuit 3 is coincident with a specific frequency in the AC signal. When the resonance state is deviated conversely, the phase difference of the two phase shift signals is deviated from 90 deg.. The amplitude of the phase shift signals is limited respectively by limiter amplifier circuit 5, 6, and fed to a detection circuit 7. Then the two phase shift signals are multiplied for a period when a pulse signal 10 is applied by the detection circuit 7 to output a signal an response to the deviation of the phase difference from 90 deg.. The detection output from the detection circuit 7 is smoothed by a smoothing circuit 8 having a comparatively longer time constant and fed to a control circuit 9. The control signal from the control circuit 9 is fed to the resonance circuits 3, 4 to apply control so that the phase difference of the phase shift signals always is kept 90 deg..

Title: Steel plate framed small motor
Inventor: ITOU KOUICHI
IPC: H02K5/00
Filed: 1979-04-13
Abstract: PURPOSE:To increase the combined rigidity without increasing the thickness of a plate by having an attaching arm formed in one body with an end braked and protruding toward both sides with a wide width at the stator side and an abruptly narrowed width at the mounting side. CONSTITUTION:A rib 11, provided on the attaching arm 9 of an end braket, has a bent section 14 and the width of the arm 9 is widened at the point near the fitting section with a stator 1, thereby allowing to obtain a high degree of modulus of rigidity. The width of the arm 9 is narrowed at the section around the mounting hole where the arm comes in contact with the surface of mounting pad of the outside tank of the washing machine and then the rib 11 is moved close to the mounting pad, thereby increasing the modulus of rigidity against the moment of the external bending deformation applied to the flat plate section 15 of the arm 9 due to the vibration of the motor. Also the decrease of the rigidity of the arm 9 is prevented with the bent section 14 by interfering the falling down of the rib 11 due to the external bending defoamtion of the flat plate 15 on the arm 9. With these two modulus of rigidities combined, the modulus of rigidity can be heightened without increasing the thickness of the plate.
