Abstract: PURPOSE: To provide a lower level of electrical noise with a rotating torque obtained without switching the drive current, by such means that, with a field magnet rotated on its own axis in accordance with a rotational position of the rotor, an interlinkage be made between the coil current and the flux through a switching of the magnetic pole at the side of facing the coil.  
     CONSTITUTION: Magnets M1 to M8, installed in the interior of a rotor 1, rotate with the rotor 1 while making three turns on its own axis in one revolution of said rotor 1 according to the gear ratio. And for instance, the magnet M1 is placed at a position, as shown in the drawing, with the bordering part of its S, N-pole facing the bordering part of the coil forward and return path portion 10a, 11b. Accordingly, in a range of rotating angle of 90° of the rotor 1, the N-pole faces the forward path portion 10a with a torque generated to rotate the rotor 1 in a direction of the arrow mark A, and in a range of rotating angle of 90° to 180°, with the rotor 1 rotated by 90° and a polarity of the magnet M1 inverted, a torque is generated in a similar direction of the arrow mark A. And at a position of rotating angle of 180°, is again inverted the polarity of the magnet M1, thereafter, in the similar way as before, a rotating torque is kept generating in the same direction.

Abstract: PROBLEM TO BE SOLVED: To reduce manhours at a job site by installing a shutter rail on the inner peripheral surface of the window opening part arranged in a wall of a building unit so as not to project from the wall surface. SOLUTION: An aluminum shutter rail 142 is also installed on the inner peripheral surface by installing a wooden architrave 141 on the inner peripheral surface of the window opening part 14 by arranging the window opening part 14 by constituting a wall 1 of a building unit A out of an inner wall panel 11, an outer wall panel 12 and a frame material 13. The shutter rail 142 does not project to the outdoor side from the outer wall panel 12 since a window frame 15 retreats to the indoor side by about 85 mm more than the surface of the outer wall panel 12 though a longitudinal directional thickness of the shutter rail 142 is about 60 mm.  A transport limit is not exceeded at transport time while the building unit can be inexpensively manufactured in large quantities in constant quality since a thing by installing the outer architrave 141 and also the shutter rail 142 on the inner peripheral surface of the window opening part 14 is manufactured in a factory. Manhours at a job site can be reduced since a required process is only to install a shutter case and a shutter at the job site.

IPC: B41J2/175
Filed: 1995-01-23
Abstract: PURPOSE: To obstruct the replacement of an ink cartridge impossible to exclude air bubbles by providing a cartridge lock member allowing a cartridge to always protrude on the same side at the time of the mounting on a frame to energize the same to an extraction obstructing position and retreating to the detachable position of the cartridge in the state fixed to a carriage. CONSTITUTION: When an ink cartridge fixing lever 13 is pushed down, since the protruding piece 41 of an ink cartridge lock member is allowed to retreat from a cartridge housing chamber 11 in this state, an ink cartridge 50 is pushed down by the falling of the lever 13 and an ink supply needle 15 breaks the seal 56 of an ink supply port 55 to be fitted in the ink supply port 55. At the same time, an ink cartridge detection piece 25 is elastically pressed to a circuit board 22 by the ink cartridge 50 to come into contact with the detection pattern 32 of the circuit board 22 to detect the mounting of the cartridge 50. Thereafter, the ink of the cartridge 50 is sucked to a recording head 12 to fill the head 12 to exclude the air bubbles penetrating into the head 12.

Title: Da converting circuit
Inventor: MARUTA HIDEICHIROU
IPC: H03M1/82
Filed: 1984-02-16
Abstract: PURPOSE:To improve the accuracy of conversion by forming a signal set to a high level only during a period corresponding to each digital signal of plural bits within the period of one period of a pulse signal having the largest weight among pulse signals. CONSTITUTION:When only an input digital signal D1 is set to a low level and remaining signals D2-D4 are set to a high level, a coincident output signal from a comparator circuit 131 is brought into a high level only during a period when both signals D1 and Q1' are at low level, and a dissident output signal is brought into a low level normally. Since an output signal of an NAND gate 31 in a signal set circuit 14 is brought always to a low level, the high level period is eliminated by the share of the pulse width of the pulse signal Q1' from the output signal from the signal setting circuit 14 in this case in comparision with the case that all the digital signals D1-D4 are set to a high level.

Title: Waveguide type optical element
Inventor: AOKI MASAHIRO
IPC: G02B6/122
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To reduce the reactive current of an optical element by forming a current/voltage impressing electrode structure in the partial area of an optical waveguide and an insulating part in a buffer layer, a clad layer, or both of the buffer and clad layers positioned in a light beam spot transforming area. SOLUTION: After a silicon oxide film 106 is formed on the whole surface of a substrate 102, proton implanted areas 107 are formed in a waveguide area having a uniform film thickness and a thick tapered area except parts of about 50μm in thickness by implanting protons into a clad layer 104 through ion implantation by using a photoresist as a masking material. After removing the photoresist mask, silicon oxide films 106 which are formed on the ridge waveguide and into which the protons are not implanted are removed. Then an upper electrode 108 is formed by using an oblique vapor deposition method so that electrodes may be formed on the side walls of the ridge. Electrode windows are formed only in the parts which do not contains implanted protons.  The reactive current of a waveguide type optical element can be reduced by providing the proton-implanted areas in no-current injected areas.

IPC: G06F3/12
Filed: 1984-02-16
Abstract: PURPOSE:To avoid a useless erasing action even in case an erasion key is pushed mistakenly by erasing the undesired stored contents of an erasion memory after detecting the paper extraction by a detector. CONSTITUTION:When paper P1 is taken out of a platen to be replaced with paper P2, this extraction of the P1 is detected by a detector 40 using an optical sensor or a microswitch. Then the detection signal is sent to a control circuit 31 from the detector 40. The circuit 31 sends a clear signal to an erasion memory 33 to erase the sentences on the p1 stored in the memory 33. Thus a useless erasing action is never carried out despite a mispush of an erasion key on a keyboard 2 when the next P2 is set to the platen. This prevents the injuries caused on the platen by said useless erasing action.
