Title: Pulse gear for rotor sensor and its production
Inventor: IMAHASHI KUNIHIKO
IPC: G01D5/245
Filed: 1985-09-03
Abstract: PURPOSE:To reduce the variance of the width and the peak value of output pulses due to an electromagnetic pickup by forming teeth of a pulse gear for rotor sensor with plastic working like press forming. CONSTITUTION:A pulse gear body 2 is plastically formed and is stuck to a front axle hub 1, and a face 3 to be detected is worked accurately by grinding. They are so set that the distance between the face 3 to be detected of each tooth and the rotation center of the axle hub 1 is constant. The face 3 to be detected after grinding has a pin angle, and width dimensions of each tooth are a certain value. Since a gap (g) between a detecting end part 5a of an electromagnetic pickup 5 and the gear 2 is stabilized as the result, the difference between a minimum value Vmin and a maximum value Vmax of an output voltage Vp detected by the pickup 5 in the side of a steering knuckle 4 is very smaller than a conventional difference and the output voltage Vp is stabilized. Similarly, a voltage period T of the sine curve is scarcely varied for every tooth and is stabilized when the axle hub 1 is rotated in a certain speed.

Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To improve aged dispersion stability by adding a sharp particle size distribution by a method wherein a dispersion medium specifies a diameter of a micro bead composed of ceramics, hard glass, hard plastic, and metal or metal compound. SOLUTION: An aqueous pigment compound prepared by adding resin, water, antiseptic agent, surfactant, stabilizer, etc., to a pigment such as organic pigment, inorganic pigment, etc., is stirred. A diameter of a fine bead composed of ceramics, metal compound of metal, zirconia, etc., is made 0.2 mm or under. After dispersion for a specific time with a filled wet type grinder, ion exchange water is added to make a concentration of a solid content a specific one, and it is filtered. Then, a coarse particle which can not be dispersed with a centrifugal separator, is removed, which is adjusted to a specific pigment content concentration to obtain an aqueous pigment fine particle dispersion liquid, and further ion exchange water or the like is mixed to prepare water-based ink.  Aqueous pigment fine particle dispersion liquid which has a sharp particle size distribution made fine particle and is excellent in aged dispersion stability can be easily manufactured in a short time.

Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To display the images of different systems on the same liquid crystal display device by simultaneously supplying the same scan signal for each adjacent scan signal line group composed of plural scan signal lines when displaying an NTSC image. SOLUTION: Since high-definition television broadcasting is the interlace scan of 2:1, in an odd-numbered field, a gate driver 4 between gate drivers 4 and 5 successively performs shift operation in every horizontal scanning period but the gate driver 5 is not operated. In an even-numbered field, however, only the gate driver 5 performs shift operation in every horizontal scanning period but the gate driver 4 is not operated. In the case of NTSC broadcasting, adjacent scanning lines are driven while being paired two by two, and the image is displayed at the central part of a display area. Namely, only 485×2=970 effective scanning lines of NTSC are used, non-use areas for 27 lines each are provided on the upside and down-side of a display screen, and the image is horizontally displayed in the area of an aspect ratio 4:3 corresponding to the dimension of 970 scanning lines.

Abstract: PROBLEM TO BE SOLVED: To eliminate the waste of a transfer paper and to lighten the burden of an operator for eliminating the transfer paper in a device by enabling an untransferred paper to be automatically used as the transfer paper by discriminating whether the transfer paper stopped on the upstream side of a transfer means is the untransferred paper or not. SOLUTION: Since the transfer paper retained in the device is the untransferred paper and clean as it is when a transfer paper detection means 101 before a carrying means detects the existence of the transfer paper but a transfer paper detection means 102 before the transfer means does not detect the existence of the transfer paper, it is ejected to the outside of the device by rotating the carrying means 19 and a paper supply means 18 reversely to a normal action time by a driving means 110. At this time, when the ejection place of the untransferred paper is previously designated to one of a paper supply cassette 23, an untransferred paper ejection part 105 and a paper supply port 106 by the operator, the untransferred paper is ejected to the designated ejection place by actuating a flapper 104 by the driving means 110.

Title: Logical level converting circuit
Inventor: MATSUO HIROYUKI
IPC: H03K19/018
Filed: 1981-12-03
Abstract: PURPOSE:To omit a terminating terminal, by taking a logical level converting circuit as a linear circuit consisting of a transistor (TR) and a plurality of resistors, and matching the input impedance of this circuit to a characteristic impedance of an input wiring. CONSTITUTION:A terminal 17 of a conventional ECL16 and a terminal 18 of a level converting circuit 15 are connected at a line. When a terminal 18 of the circuit 15 is a high level, since a reference voltage from a terminal 23 is set to turn off a TR24, a high level of CML appears at a terminal 20. When the terminal 18 is a low level inversely, the TR24 turns on and a low level of CML appears at the terminal 20 depending on the value of a resistor 25. An externally mounted termination resistor is required by putting this circuit 15 in an integrated circuit chip. Further, since the circuit 15 is not a phase inverting switch circuit, the delay is small.

Title: Raising method for grooving for inside surface grooved pipe
Inventor: NAKAMORI KUNIO
IPC: B21H3/00
Filed: 1988-08-04
Abstract: PURPOSE:To reduce manufacturing cost by starting a feed operation of a pipe to be worked after the rotation of a rotary forming tool is started, inserting a grooved plug at the time point when the speed ratio of the tool and the pipe reaches a value at the time of steady working and increasing both speeds. CONSTITUTION:First of all, a rotary head 16 being a rotary forming tool is brought to rotational operation, and after a prescribed time lapses, the feeding operation of the pipe 2 is started. At the time point when the ratio R of a rotational speed VR of the head 16 and the feeding speed Vr of the pipe coincides with the steady speed ratio Ro set in advance, both speeds are fixed and a grooved plug 12 is inserted. Subsequently, after the working state is checked, the speeds VR, Vr are increased, while holding the ratio Ro, and grooving is executed. Since grooving is started at lower speed than target steady speed, length of the pipe 2 which becomes a scrap is reduced. In such a manner, since the manufacturing yield of a product is improved, the manufacturing cost is reduced.
