Title: Display device
Inventor: MIYABE KAZUHIRO
IPC: H04N5/05
Filed: 1989-12-14
Abstract: PURPOSE:To attain optimum phase adjustment by providing a blanking detection circuit for a video signal and a pulse width expansion circuit of a horizontal synchronizing signal, ANDing outputs of both circuits and adjusting the phase of the signal with a pulse width of the AND. CONSTITUTION:A blanking detection circuit 3 detects a horizontal blanking of an inputted RGB signal. On the other hand, a pulse width expansion circuit 4 expands the pulse width of the horizontal synchronizing signal HD till the width is the same as the blanking width. Then an AND gate 5 ANDs the HD signal expanding the pulse width and the blanking signal. When the HD is most advanced, the HD has the same width as the blanking signal and when the HD is most lagged, the blanking signal has the same width as the HD and the phase is detected as the pulse width. An HD phase adjustment circuit 6 is adjusted by using the pulse width to attain the optimum phase adjustment.

Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnet roller for improving magnetic characteristics by sufficiently orienting magnetic grains, and a method for manufacturing a magnetic piece, and a magnet roller having high magnetic characteristics. SOLUTION: While a roller main body 12 is being formed, a magnetic field in which magnetic grains are oriented is generated from an outer peripheral face 13 side of a roller main body 12, and a magnetic field with the same polarity as that of the magnetic field is generated from an inner peripheral face 14 side of the roller main body 12 faced to the outer peripheral face 13 so that the roller main body 12 can be oriented and magnetized. Thus, it is possible to suppress a line of magnetic force 26 going from the outside peripheral face side to the inner peripheral face side (the central direction of the magnetic roller) of the roller main body, and to direct the line of magnetic force 26 of the roller main body 12 to the adjacent pole so that a circular arc can be plotted from the outer peripheral face 13 side.

Abstract: PURPOSE:To give a convenience to a circuit connected to the next stage by outputting two kinds of pulses inverse in logic to each other to be used as phase comparison outputs. CONSTITUTION:The 1st leading detection circuit D1 detects the leading point of time of a 1st input signal S1, a 1st flip-flop FF1 is set and the two outputs of opposite logic are outputted to 1st and 2nd output terminals OUT1, 2. Then a 2nd leading detection circuit D2 detects the leading point of time of 2nd input signal S2 and the two outputs of opposite logic are outputted to 3rd and 4th output terminals. In such a case, the rest 2-input NAND gate 11 is reset together with the flip-flop in response to the inverted output of 1st and 2nd flip-flops and the output state of the 1st and 2nd flip-flops in pairs is changed. Thus, two kinds of 'H' and 'L' level are outputted as signals representing the phase difference of the input signal to serve a convenience to the circuit of the next stage.

Title: Level conversion circuit
Inventor: KONDO KENJI
IPC: H03K5/02
Filed: 1988-12-23
Abstract: PURPOSE:To prevent malfunction and to obtain a high speed level conversion circuit by using a signal level transit detection circuit so as to detect a change in an input signal, thereby varying the current capability ratio of a PMOS transistor(TR) and an NMOS TR. CONSTITUTION:When a level of an input signal IN changes from L to an H level in a TTL level, an input signal transition detection circuit C detects the change. Then an output signal VA11 from the circuit C goes to H level at a time T2 with a prescribed time delay, and an NMOS TR Q3 is turned on. The relation between the current capability ratio RbetaI of a PMOSTR Q11 and an NMOS TR Q12 being components of an input inverter and a current capability ratio Rbeta3 of MOS TRs Q11, Q12, Q13 is expressed in equation 1, where betaQ11, betaQ12, betaQ13 are current capabilities of the TRs, respectively. That is, since the capability ratio RbetaII when the NMOS TR Q13 is set smaller than the capability ratio Rbeta1, even if the source level of the NMOS TR is fluctuated due to the change in the operating current of a CMOS LSI, the level of the output voltage VOUT keeps the L level of the CMOS level.
