Title: Magnetic head
Inventor: HARA KENJI
IPC: G11B5/187
Filed: 1984-04-12
Abstract: PURPOSE:To obtain a magnetic head which has virtually no change of initial permeability due to temperatures with a magnetic recording/reproduction head and has small output variance, by adding the garnet of a specific composition of Y, Gd, Fe and O together with the saturation density smaller than the magnetic head itself to a gap part. CONSTITUTION:For the garnet as shown by a formula, a single phase of 0.9<= x<=2.15 is used or the garnet of 0<=x<=3 is comboned by >=2 phases to obtain a mean composition of 0.9<=x<=2.15 together with the temperature change of initial permeability set at <=+ or -0.2%/ deg.C. Such a material is attached to thegap part of a magnetic recording/reproduction head. Thus the garnet of a specific composition having the smaller saturated magnetic flux density than the ferrite material of he magnetic head itself is used between gaps. As a result, the output variance of a magnetic head can be reduced even in case a temperature change is produced by the ambient temperatures while the head is used or the heat generated by the friction of a recording medium.

Title: Ink jet recording device
Inventor: SUWABE YASUSHI
IPC: B41J2/175
Filed: 1995-03-29
Abstract: PURPOSE: To make a heat melt ink which reduces power consumption usable by providing a powder ink flying means which makes a powder ink conveyed to a powder ink flying position fly to a record head. CONSTITUTION: A powder ink 3 with thinned layer is electrified with friction at the time to be regulated by the thin layer or charged with electricity from a regulating member 11 so as to have positive or negative electric charge uniformly. A powder ink carrier 2 rotates in the direction of an arrow A by holding the thin layer powder ink 3 on its surface. Accordingly, the powder ink 3 being held on its surface moves to a powder ink flying position 12 opposite to a record head 10, and further, it is set to return to a part opposite to a powder ink storing means 1. Thus, the powder ink does not stay continuously in the powder ink flying position of a powder ink conveying means and heat of a record head is hardly transmitted to the powder ink, so that a trouble caused by ink fusion is not generated.

IPC: H04N5/66
Filed: 1994-04-11
Abstract: PURPOSE:To reduce the power consumption of an active matrix type liquid crystal display. CONSTITUTION:A pulse width modulation signal complied with the gradation of a video input signal is generated by means of a pulse width converting part in a display signal circuit 300, a driving voltage for a liquid crystal cell is sent to a data signal line DL-i for a period set by the pulse width modulation signal by means of a switch part and the data signal line DL-i and a pixel electrode 11 become a high impedance state in the other period. A lamp driving voltage is applied on a common electrode 22 from a lamp voltage generating circuit 400 and a TFT-LCD p[art TC1 performs multilevel display based on the potential difference between the common electrode 22 and the pixel electrode 11. When the data signal line DL-i becomes a high impedance state, the potential of the data signal line DL-i is changed by following up the lamp driving voltage owing to the wiring capacity. The wiring capacity suppresses the spread of the potential difference between the common electrode 22 and the pixel electrode 11 in the high impedance state.

Title: Timer circuit
Inventor: WATANABE KO
IPC: H03K17/28
Filed: 1989-03-24
Abstract: PURPOSE:To always secure the output of an output when a prescribed time lapses right after a power switch is turned on by discharging the electric charge out of a time limiting capacitor via a bias resistance and the discharging resistance of a voltage deciding part in an extremely short time when a power supply is switched off. CONSTITUTION:A rectifier (diode) 6 and a discharging resistance 7 are provided to discharge the charging electric charge of a time limiting capacitor 3. Thus the electric charge of the capacitor 3 is discharged in an extremely short time via the diode 6, the resistance 7, and the bias resistance Rb of a voltage deciding IC 4 respectively. Therefore no signal is outputted before a prescribed time lapses even right after a signal is outputted from the IC 4 or even when a power switch 2 is turned on again after it is once turned off during the clocking of the IC 4 since the electric charge of the capacitor 3 is kept approximately at zero. consequently, a signal is always outputted when a prescribed time lapses right after the switch 2 is turned on.

Abstract: PURPOSE:To reduce the access time without complicated manufacture process, by boosting a word line at a voltage higher than the power supply voltage for a memory cell at the selection of the word line and the power supply voltage for a peripheral circuit other than the cell. CONSTITUTION:When a control input VC is VDD initially and changes to a VSS, the voltage VS is boosted to 2 VDD at a boosting circuit 21. Further, an input voltage Vin is VDD initially and a word line 10 is VSS at a word line drive circuit 20. When the word line 10 is selected, the voltage Vin is VSS after the potential of the control input VC changes from VDD to VSS, the voltage VS is impressed to the word line 10 via a drive FETP6 and the line 10 is boosted. Thus, at the selection of the line 10, the leading speed of the voltage of the line 10 is quickened by boosting the line 10 at a voltage 2VDD higher than the VDD for a memory cell 11 and the VDD for the peripheral circuit other than the cell, and the effective driving ability of the bit line is improved.
