Title: Prevention of cockle in rimmed steel plate by tension leveler
Inventor: KUMASAKA KIYOSHI
IPC: B21D1/05
Filed: 1978-03-27
Abstract: PURPOSE: To obtain good quality steel plate by preventing the occurrence of cockle by eliminating the difference in plastic elongation between core portion and rim portion by the use of a specific form of tension roller when the flatness of rimmed steel is corrected by tension leveler.  
     CONSTITUTION: Based on an equation and experimental results (separately mentioned), the difference in diameter, Δd, between both contacting ends of the central straight portion 3 of the tension roller 1 provided on a tension leveler and the rimmed steel plate 2 is set up to Δd=KΔδ/E [K is constant (1500 to 4500), Δδ is difference in yield stress between the central part and the both ends of steel plate, and E is Young's modulus], and also a tension roll 1 with the taper of the relationship B/2≤L 1 ≤B-B e  [B is the whole width of steel plate and B e  is the total rim layer width of the both ends of steel plate] is used for the straight portion L 1  of the roller central part. Thus, a difference in diameter is made between the core portion 4 and the rim portion 5 and thus their plastic elongations become equal, preventing the occurrence of cockle. Thus, good quality steel plate can be obtained.

Title: Picture displaying device
Inventor: ITO HIROSHI
IPC: H04N5/46
Filed: 1989-02-15
Abstract: PURPOSE:To reduce baking due to local use of a screen by moving the entire display screen continuously or stepwise when a displayed pattern is smaller than the screen of the screen display device so as to use the entire screen of the screen display device. CONSTITUTION:When a timing adjustment circuit 7 supplies a synchronizing signal phi2 with a delay time DELTAt to a horizontal deflection circuit 8, the position of the display picture formed on the display device screen scanned by a horizontal deflection current iY is the center of the screen. When the adjustment circuit 7 supplies the synchronizing signal phi1 whose phase led by DELTAt from the synchronizing signal phi2 to the horizontal deflection circuit 8, the position of the displayed picture is moved relatively to the right of the display device screen. Conversely when the adjustment circuit 7 supplies the synchronizing signal whose phase is delayed by DELTAt from the synchronizing signal phi2 to the horizontal deflection circuit 8, the location of the display picture is moved to the left side of the display device screen. A timing control circuit 72 changes the delay of the synchronizing signal phi as a prescribed time elapses to move the entire display picture gradually in the horizontal direction of the screen.

IPC: G09G3/18
Filed: 1990-02-19
Abstract: PURPOSE:To additionally darken a dark display so as to have a better contrast by disposing the absorption axis of crossed nicols in the position where the time average light quantity displaying two states; bright and dark, at every dot with time divided driving. CONSTITUTION:The absorption axis of the crossed nicols is disposed in the position where the time average light quantity of the dark state is darkest at the time of displaying the two states; dark and bright, with the time divided driving by impressing a voltage of an AC waveform between transparent electrodes 3 and 3 of the ferroelectric liquid crystal display element. The time average light quantity refers to the value obtd. by time-averaging the integrated value of the transmitted light quantity in the time when one screen is rewritten (one frame time) in one dot displayed in the brightness or darkness. The absorption axis of the crossed nicols refers to the polarizing direction of the polarizing plate nearer the light source of two sheets of the polarizing plates 1 which are combined perpendicular. The state of the dark state is put into the optically dark state as well by the improvement in the absorption axis of the crossed nicols. the better contrast is thus obtd.

Title: Class 'ab' amplifier
Inventor: NOGI AKIHIKO
IPC: H03F3/30
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To obtain the class 'AB' amplifier which can be prevented from deteriorating in the performance as an amplifier under the influence of the operation point of a circuit connected behind it. SOLUTION: A gain G1 of a 1st amplifier circuit 61 and a gain G2 of a 2nd amplifier circuit 62 are set so that they are related G1>G2. Consequently, when a circuit such as an active filter is used while connected behind the class 'AB' amplified without interposing any capacitor, a current I continuously flows to a PMOS transistor 34. This current I can be increased by lowering the potential at a point J, which can be actualized by small voltage variation at the point J, as compared with a case wherein both the gains are equal because of G1>G2. Namely, since the variation in the current flowing to an NMOS transistor 35 is small, the decrease in its driving capability is reducible. Consequently, the class 'AB' amplifier have performance similar to that when a capacitor is used for a conventional circuit without using capacitors.

Title: Reproduction input amplification circuit and vtr
Inventor: SASAKI HIROYUKI
IPC: G11B5/027
Filed: 1994-03-08
Abstract: PURPOSE:To increase the bandwidth of frequency characteristics by changing the phase of a feedback signal according to the frequency within the range of negative feedback. CONSTITUTION:A negative feedback path 6 consists of a feedback amplifier, a feedback resistor 8, and a phase rotation circuit 9. The phase rotation circuit 9 consists of a series circuit of a capacitor C2 and a resistor R2 and the impedance of the capacitor C2 decreases as the frequency of the reproduction input signal increases, thus also reducing the impedance of the rotation circuit 9. Therefore, those bypassed to the ground increase among amount of feedback and the amount of negative feedback to the input of a reproduction input amplifier 3 decreases, thus equivalently decreasing the capacity of an input capacitor C1. It means that the phase of the negative feedback path 6 was rotated to the positive side.

IPC: G03B21/11
Filed: 1986-02-21
Abstract: PURPOSE:To omit fine positioning of assembling and to simplify a structure by operating an operation member to change the density of a density changing member. CONSTITUTION:When an operation control 35 is pressed in the direction A against the exciting force of a spring 41, frictional disks 37, 38 are contacted with each other and a shaft 36 is coupled with a driving shaft 27. When the control 35 is turned under said status, a disk 39 is rotated in the same direction and the density is increased at a detecting position of a sensor 50. Thereby, the output of the sensor 50 is reduced, the output change is detected by an output change detecting circuit and an output reduction signal is sent to a brake control circuit and a clutch control circuit, so that a clutch mechanism 26 is turned on and a brake mechanism 32 is turned off. Thus, a capstan roller 11 is rotated and a film is carried in the forward direction by rotating the control 35 in the clockwise direction while pressing it in the direction A. When the control 35 is rotated in the counterclockwise direction, the density at the detecting position of the sensor 50 is thinned and the output is increased. Thus, the mechanism can be simplified.
