Abstract: PURPOSE: To reduce the torque variation of an electric motor vehicle due to conversion of triangular wave in frequency by providing a period for providing six times frequency while converting the frequency of the triangular wave from 9 times of sine wave to 3 times.  
     CONSTITUTION: An induction motor 5 for driving an electric motor vehicle is energized through a pantograph 2 and an inverter 3 by a variable frequency and voltage power supply. The frequency f 1  of a pulse generated by a pulse generator 6 directly coupled to the motor 5 is converted by a frequency-to-analog converter 7 to analog voltage V 1 , and a voltage ΔV corresponding to n times of predetermined slip frequency is added to the analog voltage V 1  by an adder 8. Then, the sum from the adder 8 is applied to a voltage oscillator 9 to generate a frequency f 2 . The frequency f 2  is divided by 1/n by a frequency divider 10 to three phases, and sine generator 11 is connected to thereby produce three phase sine wave of f 2 /n. Triangular wave generators 20-1W 20-5 generate 1W15 times of the sine wave to a triangular wave switching circuit 27, which switch the frequency of the triangular wave as reaquired.

Title: Water measuring instrument of grain drying machine
Inventor: NAGAI HIROSHI
IPC: G01N27/04
Filed: 1986-06-02
Abstract: PURPOSE:To remove residual grains on electrode rollers and grain flour between the electrode rollers and to improve workability and measurement accuracy by carrying on the rotation of the electrode rollers for a specific time even after the end of measuring operation. CONSTITUTION:When the water of grains being dried by a drying machine is measured, grains are supplied, one by one, from a supply mechanism 4 to a hopper 5. A couple of electrode rollers 10 are installed below the hoper 5 and variation in resistance between both electrodes when a gain 9 passes between the electrode rollers is extracted as a water voltage. When grains are supplied from the outside, an operator supplies a specific amount of grains in a sample cut 2, but this supply amount is not constant in general. That results in deterioration in the workability and the cause of errors in measurement if there are still grains remaining on the electrode rollers when the electrode rollers stop at the end of the water measuring operation. For the purpose, when the grains are supplied from outside to take a measurement of water, the electrode rollers are driven for the specific time even after the end of the measuring operation to remove grains and grain flour from the electrodes completely.

Title: Focus servo pull-in device of optical information reader
Inventor: NAITOU RIYUUICHI
IPC: G11B7/085
Filed: 1982-07-24
Abstract: PURPOSE:To always detect a point distant away from a real focused point despite the variance of the detecting gain of a focus error detecting means, by comparing the focus error signal obtained after it passed through a 1-circulation loop gain control means with the reference voltage. CONSTITUTION:The comparison input of a comparator 6 is used as a focus error signal (a') which passed through a gain control volume 3 and not a focus error signal (a), i.e., the output of a focus error detecting means 1. The volume 3 compensates the variance of a 1-circulation loop gain to obtain fixed servo characteristics at all times. The variance of the 1-circulation loop gain contains the most dominant sensitivity variance of the means 1 in addition to the variance of the circuit gain due to the variance of resistance value, etc. and the sensitivity variance of a focus actuator 10, etc. Thus adjustment of the 1-circulation loop gain is the same as the adjustment of the sensitivity variance of the means 1 if other variance are ignored.

Title: Plasma display panel, phosphor, and production of phosphor
Inventor: MIYASHITA KANAKO
IPC: H01J11/42
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To obtain a phosphor which can give a good panel luminance even when used in a plasma display panel with a cell construction as fine as that of a high-vision panel by preparing a phosphor through a process contg. a step of synthesizing a phosphor and a step of annealing the resultant phosphor by heating. SOLUTION: The process further contains, between the synthesis step and the annealing step, a step of granulating the phosphor into phosphor particles having a specified average particle size. The granulation step is effective esp. when relatively fine phosphor particles having a max. (or average) particle size of about 3 μm are used. By conducting the annealing step at a lower temp. (or in a shorter time) than that of the synthesis step, the aggregation of phosphor particles can be prevented and a phosphor with a desired particle size can be obtd. When the phosphor particles produced are spherical, the filling ratio of a phosphor layer is increased, enabling the further improvement in panel luminance to be expected.

Title: Magnetic bubble memory element
Inventor: YANAI MASAHIRO
IPC: G11C19/08
Filed: 1984-06-25
Abstract: PURPOSE:To eliminate a transfer error generated in the vicinity of a 180 deg. turn corner and to improve a transfer characteristic by setting the height of a transfer pattern having a pattern frequency lower than that of a basic transfer pattern lower than the height of the basic transfer pattern. CONSTITUTION:The height of, for instance, the 4th and 5th tansfer patterns 14' and 15', which are arrayed in the vicinity of a reverse 180 deg. turn corner pattern 16, is formed lower than that of the 1st basic transfer pattern 11. Thus a distance l between a vertex of the 4th transfer pattern 14' and 5th transfer pattern 15' opposite to the former increases, therefore, such a tansfer error does not occur that a magnetic bubble on the 4th transfer pattern 14' is attracted by an attracting magnetic pole produced at a foot of the 5th transfer pattern 15' and slips out accordingly.

Title: Thermal recorder
Inventor: YAMAMURO HIROSHI
IPC: B41J2/355
Filed: 1983-07-18
Abstract: PURPOSE:To facilitate the discrimination of input signals, which are close to each other and to prevent the deterioration of a heating element of a thermal head, by recording one signal in a red color when the difference in two input signals is lower than a specified value, and recording the signals in a black color at the opposite case. CONSTITUTION:A difference detecting part 1 always detects the difference between two input signals (i) and (j). When the difference exceeds the reference value from a reference-value generating part 2, a normal mode is outputted. At this time, one color recording of both signals is performed in a black color, at which a driving current for a heating element is small. When the difference signal becomes lower than the reference value, a comparator 3 is inverted from the normal mode, and a special mode is outputted. At this time, the recording of one signal is performed in a red color, at which the driving current for the heating element is large, and the recording of the other signal is performed in the black color. Thus the discrimination of the input signals, which are close to each other, can be facilitated, and the deterioration of the heating element of a thermal head 14 can be prevented.

Title: Image recording method
Inventor: MOTOYAMA EIICHI
IPC: B41J29/38
Filed: 1993-05-31
Abstract: PURPOSE:To realize the improvement of image quality and a high speed at a low cost when image data, which are narrower than the maximum recording width of a recording head, are recorded. CONSTITUTION:A recording head, wherein a plurality of recording elements are aligned, is moved into the orthogonal direction (main scanning direction) with respect to the aligning direction of a plurality of the recording elements, and the scanning is performed. After the end of the scanning, a recording medium is moved into the orthogonal direction with respect to the scanning direction by a distance corresponding to the recording width, and the feed is performed. This operation is repeated, and the formation of the picture of one plane is completed. When the image data, which have the narrower width than the maximum recording width of the recording head at the reducing recording are recorded, a plurality of the image data having the aforementioned width are combined. The image data for the maximum recording width are recorded all together once by using a plurality of the recording elements. For example, when the demagnification rate is 50%, the image data at the first line are stored in a memory 210. When the image data at the second line are inputted, the first-line data are read out of the memory 210 and combined with the second-line data. The result is outputted into the recording head.
