Title: Picture signal producing device
Inventor: SATOU YOUJIROU
IPC: H04N1/19
Filed: 1979-05-26
Abstract: PURPOSE:To always secure the steady output signal for the image sensor, by giving the control to the gain of the gain control circuit of the picture signal via the control signal which corresponds to the time interval of the shift amount detection pulse. CONSTITUTION:Shift amount detection pulse Pd is delivered from shift amount detector DS every time both the original and image sensor IS shift in the secondary scanning direction and by the fixed relative shift amount, and then applied to driving circuit DC and frequency/voltage converter FVC each. Time interval Tp of pulse Pd varies according to the fluctuation of the secondary scanning. And converter FVC produces DC voltage Sd featuring the value corresponding to the frequency of pulse Pd to apply it to inverter INV. Thus the polarity of voltage Sd is inverted, and gain control signal Sc is applied to gain control circuit Gc. On the other hand, pulse Pd gives the control to circuit DC and then drives sensor IS. Sensor IS starts the main scanning with every position of the producing time of pulse Pd, and then produces picture signal Sa to apply it to reading amplifier A. Amplifier A amplifies the signal to supply it to circuit Gc. Thus the picture signal free from the fluctuation of the signal level can be delivered.

Filed: 1987-03-23
Abstract: PURPOSE:To stabilize the tracking control just after track jump by setting the time constant of a differentiation circuit part at the time of track jump so that the point where the polarity of the square wave signal applied to a light beam driving coil is inverted coincides with the zero-crossing point of a tracking error signal. CONSTITUTION:A differentiation circuit part 11 is provided in the preceding stage of a pulse generating means which converts the tracking error signal to a pulse signal for the purpose of detecting the zero-crossing point of the tracking error signal. At the time of track jump, the time constant of the differentiation circuit part 11 is so set that the point where the polarity of the square wave signal, which is generated based on the phase-advance tracking error signal and is applied to a light beam driving coil 8, is inverted coincides with the zero-crossing point of the tracking error signal. Consequently, the impulse sum of the square wave signal applied to the light beam driving coil 8 is zero when the light beam is on a second track after track jump. Thus, the tracking control is stabilized.

Title: Recorder
Inventor: MYOKAN ISAO
IPC: H04N1/00
Filed: 1989-03-17
Abstract: PURPOSE:To simplify the structure of recorder by installing a regulator plate with a slip-off preventer sliding on a track at the opposite side of a reference plane, and detecting a recording paper size with travel of this regulator plate. CONSTITUTION:A regulator plate 28 is loosely fitted in slide grooves 23a and 23b installed in both inside and lower parts of a storage chamber for recording paper 22 with an overhang pin and made free of slide motion. An overhang pin at the lower part is made impossible to be slipped off by an E ring 29 at a position where it is inserted into the slide groove 23b. In addition, a wire 32 provided with a spring 35 is tightly attached to this lower overhang pin, and this wire 32 is rolled on a pulley 30 of a potentiometer 33 and another pulley 31 at the opposed end. Consequently, this potentiometer 33 is rotated by movement of the regulator plate 28, and thereby a paper size by a travel position of the regulator plate made contact in the cross direction of the recording paper 22 is thus detected. Moreover, strong pressure of the recording paper 22 and the regulator plate 28 is kept back owing to the spring 35. With this constitution, any loss of the regulator plate 28 is prevented from occurring and, what is more, the recording paper size is made detectable with the single potentiometer 33, thus constitution becomes simplified.

Filed: 1992-03-24
Abstract: PURPOSE:To obtain the subject modifying agent effective in improving the adhesivity of carbon fiber to a matrix resin by forming a polyimide resin composed of a specific primary diamine and an aromatic tetracarboxylic acid on the surface of a reinforcing carbon fiber. CONSTITUTION:A symmetric aromatic para-substituted primary diamine of formula [X is O, SO2, S, C=0, CH2, C(CH3)2, C(CF3)2 or direct bond] is made to react with an aromatic tetracarboxylic acid dianhydride (e.g. pyromellitic dianhydride) in nitrogen atmosphere to obtain a polyamic acid solution. A carbon fiber bundle is immersed in a liquid produced by diluting the above solution, dried with heat and heated in nitrogen atmosphere to convert the polyamic acid into polyimide and obtain a reinforcing carbon fiber having polyimide resin formed on the surface of carbon fiber. The obtained fiber has improved adhesivity to a matrix resin, especially thermoplastic resin and gives a molded article having remarkably improved mechanical strength by mixing with the resin and molding the mixture.

Title: Line segment clipping method for multi-window
Inventor: OKAMOTO RIKIYA
IPC: G06T11/00
Filed: 1988-03-19
Abstract: PURPOSE:To speed up clipping processing by dividing an area into the plural partial areas with straight lines including the boundary side of a multi-window, storing only the sides which are not shared by the adjacent areas, and calculating only the intersection between the given line and the respective memory sides. CONSTITUTION:First, the area is divided 10 into the plural partial areas by the straight lines including the respective boundary sides of the two overlapped and displayed windows. Next, only the sides, whose adjacent partial areas are not shared, out of the all boundary sides are stored 12. Further, the all intersections of a given line and the respective storage sides are calculated 14. By the intersections and the position information of the lines, the components of the lines can be clipping-displayed 16 only in the window displaying area. Consequently, the boundary sides shared by the adjacent partial areas are excluded from the calculation of the intersections, and the line segment clipping processing can be made speedy.

Title: Motor operated valve
Inventor: MOCHIZUKI KENICHI
IPC: F16K1/42
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a motor operated valve in which the opening gap between a valve seat part and a valve member of the valve disc does not vary by provid ing a taper surface permitting the radius of the valve seat part to reduce in the direction of a valve chamber as well as by providing a surface permitting the valve member of the valve disc to make contact with the taper surface. SOLUTION: A valve member 17a is made of Teflon, and a valve seat part 21 is made of brass, so that they are different in coefficient of thermal expansion due to the difference in material. When they are warmed due to elevation of the temperature of fluid, both expand. However, the valve member 17a with greater coefficient of thermal expansion expands more than the valve seat part 21, and the valve member 17a is positioned arround the valve seat part 21. As a result, a recessed-annular taper contact surface 17a2 of the valve member 17a becomes greater in its annular diameter, and, owing to the effect of expansion, moves in peripheral direction aparting from the recessed-annular contact surface of the valve seat part 21.  Thus, the recessed-annular taper contact surface 17a2 of the valve member 17a neither make contact with the convex-annular contact surface of the valve seat part 21 nor prevent reduction of the opening gap a between them.

Title: Temperature compensating oscillator
Inventor: ARUFUONSU ZUMUSUTETSUGU
IPC: G04G3/02
Filed: 1980-05-21
Abstract: A signal generator having a digital temperature compensation circuit contains high and low frequency quartz oscillators (HF and NF), the low frequency oscillator being used for temperature compensation. Both oscillators are manufactured such that the descending portion of the temperature dependent parabolic frequency curve of the low frequency oscillator passes through the temperature inversion point of the parabola of the high frequency oscillator. The frequencies of both oscillators are first adjusted such that the ratio thereof is inversely proportional to the ratio of the parabolic temperature coefficient, i.e., f1:f2= beta 2: beta 1. Subsequently two substantially identical reference frequencies are adjusted and, by feeding back the output frequency, combined in such a manner that an output frequency independent of temperature is produced which is determined substantially by the high frequency oscillator. The signal generator is thus temperature compensated and, due to the use of a high frequency oscillator, has much better properties with regard to aging and frequency stability than a low frequency oscillator.
