Patent JP-S59210528-A (JP)
Title: Tracking method
Inventor: SASAKI KIYOSHI
IPC: H04N5/7826
Filed: 1983-05-13
Abstract: PURPOSE:To attain the satisfactory reproduction of track width of several mu by using two driving means which vibrate a head in the width direction of a signal track to produce a relative motion between the head and a medium in the lengthwise direction of the signal track and a signal processing circuit which obtains the driving signal for driving means from the reproduction output of the head. CONSTITUTION:A vertical recording medium 10 undergoes the total DC erasion in the direction toward the surface of the medium, and oblique line parts 11 of a signal bit are magnetized in the direction distant away from the surface of the medium. A bit group 12 forms a track. The gap of a tracking head or the track width T1 of an MR element 13 is much larger than the wavelength of a signal bit. A mark 14 means the gap of a reproduction head for signal bit or an MR element. In this case, the MR element is not used to a head and heads 13 and 14 form a head 2. This head is moved toward A and therefore the signal bit on a track is reproduced by the reproduction head 14 for signal bit. While the tracking head 13 reproduces the tracking signal with vibrations toward an arrow B. If the amplitude of the direction B is set at 2a, the head 13 crosses a track part and goes and comes back through a non-track part at both sides of the track part respectively as long as 2a>Tw is satisfied.

Title: Discharge lamp lighting device
Inventor: ONISHI MASAHITO
IPC: H05B41/24
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To suppress power consumption and improve efficiency in a circuit by making the value of the voltage of an energy accumulating means for supplying energy to step voltage generating means at a trough part of an ac power voltage agree with the peak value of an output voltage on a side higher than discharge characteristic of a discharge lamp. SOLUTION: A lamp current is large, and the voltage of discharge lamp characteristics is low, when a discharge lamp fully lights up. When attempting to light stably, ratios of high and low periods becomes close, a voltage VdcF of a smooth capacitor C0 is set as low as a voltage equivalent to three capacitors, and a capacitor for power conversion requires only three switching elements for switching control to effectively utilize the elements. When modulated light lights up, a lamp voltage is low and a characteristic voltage is high. A rate of a high applied voltage period is smaller than that of a low applied voltage period. Thus, a voltage VdcD of the smooth condenser C0 is set so that a control range for preventing a discharge lamp failure is set higher than a maximum voltage, and switching elements are effectively used to reduce power consumption and provide stable lighting.

Title: Inverter
Inventor: KAGA ATSUSHI
IPC: H02M7/5387
Filed: 1980-06-19
Abstract: PURPOSE:To prevent the occurrence of a voltage when a switching element becomes ON by connecting a capacitor having the prescribed capacity between intermediate taps of respective saturable reactors thereby suppressing the heat loss when the switching element becomes ON. CONSTITUTION:When a transistor 2 is ON state, a current will flow in a route designated by solid lines, and the energy of a saturable reactor 14 is divided into energy stored in the core of the reactor 14 and energy stored in an air core inductance of a coil. When the transistor 2 is interrupted OFF at this time, the energy stored in the core of the reactor 14 and the energy stored in the coil connected to the power of the inductance and a capacitor 19 are transferred to the capacitor 19. As a result, the voltage of the transistor 2 will not increase due to the reactor 14. When the transistor 2 becomes ON, the current of the capacitor is controlled by the part between the capacitor 19 of the reactor 14 and the transistor 2.

Title: Current limiting circuit
Inventor: HATANAKA HIROSHI
IPC: H03G11/00
Filed: 1987-04-08
Abstract: PURPOSE:To determine a current control value according to the ratio of resistances and to accurately determine a current limit value by controlling the operation of a current mirror circuit with a voltage developed across a resistance interposed in the flow passage of a load current. CONSTITUTION:This circuit consists of constant current sources 1 and 2, transistors(TR) Q1 and Q2, resistances R1 and R2, and current amplifiers A1 and A2. When a current I3 increases in this constitution, a current I5 also increases and a current I6, therefore, increases as well; and then I6<I5 holds later and a deficient current I5-I6=I7 is supplied from the current amplifier A2. Consequently, a current flowing to the current amplifier A1 so far decreases and the current I3 decreases, thus performing current limiting operation. Then when the current decreases, the current I5 also decreases and a balanced state is entered when I5=I6. When I4=I6, the TRs Q1 and Q2 constitute the current mirror circuit and an equation I holds. In general, this circuit is so designed that I3>I4, so the equation I is changed into an equation II. Consequently, the current I3 to be limited is proportional to the ratio of the resistances R1 and R2.
