Title: Manufacture of armature winding for changeable number of pole
Inventor: OOHASHI KOUJI
IPC: H02K17/14
Filed: 1978-09-11
Abstract: PURPOSE: To change the number of poles, by dividing the windings of each phase into a number of groups equal to the least common multiple of the number of poles, placing the groups at almost an equal spacing, allocating the windings of all phases to a number of almost equal blocks identical with that of operated poles, and  causing electrical currents to flow through the blocks in different directions.  
     CONSTITUTION: When the number of the poles is set at two, four or six, a number of groups of windings W 1 ∼W 12  equal to twelve, the least common multiple, are  placed at an almost equal spacing for each phase. The windings of all the phases  are allocated to a number of almost equal blocks identical with that of the poles. As  for a two-pole machine, a block B 21 ' consists of groups W 1 ∼W 6  of windings and  another block B 22 ' consists of groups W 1 ∼W 12  of windings. Electrical currints are  caused to flow through each identical block of windings in the same diredtion. The  direction of the electrical currents differs between the adjacent blocks of windings.  The poles are produced by the blocks. The number of the poles can thus be  changed.

Title: Image sensor
Inventor: FUKUOKA KENJI
IPC: H04N5/335
Filed: 1981-07-16
Abstract: PURPOSE:To make the integrating time at each cell equal to each other and bring out the sensitivity of a sensor to a maximum, by starting the integration by performing the reset of each cell of solid-state image pickup elements immediately after the readout of the picture information of the cells. CONSTITUTION:It is presumed that only a vertical scanning line W-k and a horizontal scanning line B-(l+1) of an SIT image sensor are excited. When the vertical scanning line W-k is excited, an SIT for reading out a cell 1 and another SIT for resetting 3-2 are put into the excited condition. Since a readout line X-l, a refresh line R-l, and a readout line X-(l+1) are selected through SITs 15-l, 19-l, and 14-(l+1) because the horizontal scanning line B-(l+1) is  also excited simultaneously, two SIT image cells 23 and 24 at the k-th in the  vertical direction and l-th and (l+1)th in the horizontal direction are set to the  readout condition. At this time, the SIT image cell 23 is set to the readout  condition while it is reset because the line R-l is selected simultaneously.

Title: Method for measuring reducibility of carbonaceous material containing chromium pellet
Inventor: MORI SHIGEYUKI
IPC: G01N31/12
Filed: 1987-05-06
Abstract: PURPOSE:To shorten the time required for a measurement operation by burning samples at different temps. in gaseous oxygen flow and separating and determining the CO2 generated by combustion of free carbon and the CO2 generated by combustion of (CrFe)7C3. CONSTITUTION:The sample pellets are ground and a prescribed amt. thereof is weighed and is put into a fuel boat 7. The boat is inserted through a sample inlet 4 of a combustion pipe 2 by a sample inserting bar 8 into the central part of a heating furnace 1. While O2 is fed through a gaseous oxygen inlet 5, the temp. in the pipe 2 is set at the preset temp. at which only the free carbon burns. The samples are held at this temp. for the prescribed period of time and the free carbon is determined from the determined value of the generated CO2. The similar operation is carried out by using the separately weighed sample pellets and the sample pellets are held for the prescribed period of time at the temp. at which both of the free carbon and the bond carbon in the form of (Cr,Fe)7C3 burn. The total amt. of the free carbon and the bond carbon is determined from the determined value of the generated CO2. The amt. of the bond carbon is determined by subtracting the previously determined amt. of the free carbon from this total value. The reducibility is then easily determined from the contents of total Fe and total Fe in the pellets and the determined value of the bond carbon.

Title: Light beam scanning device
Inventor: HASEGAWA SHINYA
IPC: H04N1/113
Filed: 1984-05-31
Abstract: PURPOSE:To prevent a shift in scanning position due to the variation in the wavelength of reproduced light by employing double-layer consitution for a hologram disk, making direction of diffraction opposite to each other, and forming at least one disk axially symmetrically about a rotating shaft. CONSTITUTION:Hologram disks H1 and H2 are formed in two layers across a spacer 7. The disk H1 is irradiated with two coherent beams of a divergent spherical wave A and a convergent spherical wave B which have wavelength lambda1 one over another. The, the disk H2 is irradiated with coherent light beams A1 and B1 with wavelength lambda2 shorter than the wavelength lambda1 one over another. When a laser beam (1) with wavelength lambda1 is incident on the disk H1, diffracted light (2) is generated and passes through the disk H2, generating diffracted light (3). This diffracted light (3) is converged on a scanning surface to make a light beam scan. The reproduced light passes through the disks H1 and H2 which have the opposite directions of diffraction and the diffracted light beams (1) and (3) are made parallel to each other. When the reproduced light varies in wavelength, the angle of diffraction of one beam is made large and that of the other is made small, so that the diffracted light beams (1) and (3) are invariably parallel. Thus, the scanning position is held constant.

CONSTITUTION:This is the spot scanning type image forming device which is used in a laser beam printer, a facsimile, and a digital copying machine, etc., and which has what is called Ftheta characteristic that parallel laser beams deflected by a rotary polygon mirror 6 are formed into the image to be in a spot state on the surface of the photosensitive body 8 and allowed to perform uniform scanning in a main scanning direction. In such a case, the laser beam condensed near the reflection surface of the polygon mirror 6 instead of a cylindrical lens is formed into the image on the surface of the photosensitive body 8 in a subscanning direction, and the deviation of a scanning line in the subscanning direction caused by the tilt of the reflection surface is lightened. Then, a density pattern is made parallel stripes consecutively in the scanning direction and cyclically in the subscanning direction.
