Patent JP-S5576359-A (JP)
Title: Developing system
Inventor: KARASAWA SHIYUUICHI
IPC: G03G15/01
Filed: 1978-12-05
Abstract: PURPOSE:To make possible color copying of two colors by forming the positive and negative  latent images corresponding to the original images of two colors of chromatic color and black on  a photoreceptor having a photosensitive layer highly sensitive to chromatic colors and a photosensitive layer insensitive to chromatic colors and developing these with the toners of mutually different polarities. CONSTITUTION:For example, in performing color copying of two colors of red and black, a  photosensitive layer 3 highly sensitive to red color is provided on the conductive substrate 2 of a  photosensitive drum 1 and a photosensitive layer 4 insensitive to red color is provided thereon.  While red light is being radiated through a red filter 17 from a light source 16, the layer 4 is negative-charged with a primary charger 5, thence it is dark-charged with a secondary charger 6, after  which it is subjected to the exposure 7 of two-color original images. In correspondence to the red,  white and black of the original images, the regions of positive and negative charging and zero  charging are formed on the surface of the layer 4. The multicolor development of red, white and  black may be accomplished by using the red and black toners of mutually different polarities with  developing devices 8 and 9. If the black toners of mutually different polarities are used with the  developing devices 9 and 10, the black and white development in which the portions of red are  not dropped out may be accomplished. Next, the images are evenly charged with a charger 11  before transfer and the transfer is accomplished with a transfer unit 18.
Patent JP-H0819109-A (JP)
Title: Controlling method for motor
Inventor: ICHIUMI YASUFUMI
IPC: H02P6/12
Filed: 1994-07-01
Abstract: PURPOSE:To prevent the slip of a tire and the vibration of a vehicle body at the time of starting and the decrease of traveling performance by detecting the number of revolutions of a motor according to the signal of an encoder, detecting the vehicle speed by a vehicle speed sensor, and filter-processing a command signal to the motor to an accelerator signal only when the vehicle speed is lower than a predetermined speed. CONSTITUTION:When an accelerator signal is abruptly increased in the state that a vehicle is stopped or at the time of low speed, a command signal to a motor is maximized at once. When the vehicle speed is at a certain speed or less at this time, the accelerator signal is so controlled as to be a curve (a) of the motor command signal. When the speed is the certain speed or more, it is so controlled as to be a curve (b). Then, at the time of starting the vehicle, abrupt torque is not generated and hence the slip of a tire and the vibration of a vehicle body can be prevented. When the tire is a certain speed or more, a filter-process is not executed, but the command remains at the motor command signal as it is, and hence accelerating performance is not dropped, and feeling at the time of starting is also improved.

Title: Method and apparatus for measuring magnetic recording signal
Inventor: SOGABE YASUSHI
IPC: H04N5/95
Filed: 1990-06-11
Abstract: PURPOSE:To measure only a displacement of a recorded signal in the lengthwise direction by moving a magnetic tape in the lengthwise direction of a track, detecting a position of a signal from pickup information obtained by an image pickup device, then detecting a displacement of the track in he lengthwise direction. CONSTITUTION:A photodetecotr 3 has a function converting a luminous quantity made incident on its area into an output amplitude and when the image formed according to the movement of a table 4 exists in a bright area entirely, the output amplitude caused in the photodetector 3 is maximized and since the incident luminous quantity is reduced when a light for a period including a horizontal synchronizing signal is formed to the photodetector 3, the output signal amplitude is reduced. As a result, the output amplitude caused when one track is scanned, then a pulse wave is caused and the displacement in the lengthwise direction of a track is measured by measuring the internal of the pulse waves of measuring the frequency of the pulse wave and checking its fluctuation. Thus, the displacement of the track in the lengthwise direction is accurately measured.

Title: Dot-matrix type serial printer
Inventor: KIYOFUJI HITOSHI
IPC: B41J19/20
Filed: 1982-09-01
Abstract: PURPOSE:To provide a serial printer short in rising distance and capable of high- speed printing, by providing two or more print head moving speeds, and controlling the speeds so that they are changed over from one to another in accordance with the print character position. CONSTITUTION:A one-line memory 1 stores print data for one line (e.g., 136 digits). A transverse feed control unit 2 controls two transverse feed speeds, high and low speeds. In the case of printing in the forward direction in order from the first digit. Although a rising distance corresponding to two characters (shown by the broken line) is conventionally required, this system only requires a rising distance corresponding to one chatacter (shown by the solid line). A control means first actuates a print head to effect an approach movement by one character from the stop position and to perform printing only for the first digit (''A'' is printed). Immediately thereafter, the speed is reduced, and the print head is suspended at the position between the second and third digits. Secondly, the print head is returned to its former stop position. Thirdly, the print head is actuated to effect an approach movement by two characters from the stop position and to perform printing from the second digit on.

CONSTITUTION:When the roll supporting plate 4 of a fixation device is set at the specific position, the lock groove 7 formed in the roll supporting plate 4 communicates with the lock groove 7' formed in the side plate 1' of the 1st main body 1. When the 2nd operation beam 8' of an operation lever is pressed up in said state, the lock piece 9 enters the lock groove 7 to lock the roll supporting plate 4, and fixing rolls 6 and 6' are brought into press contact with each other to be set in a normal state. When the operation beam 8' of the operation lever is lowered, the lock piece 9 moves toward the lock groove 7' and its lock is released, so the roll supporting plate 4 is opened around a shaft 5 as shown by an arrow G and paper jamming in the fixation device is removed easily.

Title: Semiconductor memory
Inventor: KAWAI HIROYUKI
IPC: G11C11/409
Filed: 1990-06-13
Abstract: PURPOSE:To speed up reading speed by making precharge potential applied to a bit line lower than a value obtd. by subtracting the threshold value of a line selection transistor from the power source potential of a memory circuit. CONSTITUTION:Since the operational speed of the memory depends on the discharge time of the precharged voltage of the bit line, the operational speed is speeded up when the precharge voltage to the bit line is lowered. A voltage source 31 with voltage lower than that obtd. by subtracting a threshold value Vthn of a line selection transistor 22 from a power source voltage VDD of the memory, are connected as the power source for precharge. When the voltage of this power source 31 is taken as E, the voltage of 'E-Vthn' (<VDD-Vthn) is precharged to a bit line A. Thus, the operational speed can be speeded up more than when the power source voltage is used as the precharge power source.

Title: Liquid crystal display device
Inventor: HAYATA YUJI
IPC: G02F1/1335
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To obtain high contrast and excellent visibility by controlling the main emission wavelength of a back light in a specified region of the perpendicular transmittance of color polarizing plates. SOLUTION: The hue of a color polarizing plate disposed on a liquid crystal panel is made different from the hue of a back light 15 disposed on the back side of the liquid crystal panel. Namely, the main emission wavelength of the back light 15 is controlled to be in the region to give <20% perpendicular transmittance of color polarizing plates 1, 2. Thereby, a display state with little leaking of light can be obtd. even when the color polarizing plates 1, 2 are used. It is preferable to control the wavelength to be in region of <5% perpendicular transmittance of the color polarizing plates 1, 2 because the light is easily cut to improve the contrast.  The liquid crystal panel consists of substrates 5, 6 produced by laminating transparent electrodes 7, 8 consisting of indium tin oxide or the like on transparent substrates such as glass, forming an alignment material thereon, and rubbing, and liquid crystal molecules held between the substrates 5, 6 have 160 to 300 deg. twist angle.
