Title: Hysteresis comparator circuit and waveform generation circuit
Inventor: TAKAI MASAMI
IPC: H03K3/0233
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To improve power conversion efficiency at the time of a light load in a DC/DC converter by installing first - third switching elements which can be turned on/off in accordance with an outer signal and first and second capacitors connected to the respective switching elements. SOLUTION: In a charging/discharging operation when the first and the third switching elements SW1 and SW3 of a hysteresis comparator circuit become closed states and a second switching element SW2 becomes an open state, a first capacitor C2 executes a charging operation when SW1 is in the closed state and consumption current I2 is supplied from a reference voltage source Vref 30. Thus, the charge of charge quantity Q2 is charged. Since SW2 is in the open state and SW3 is in the closed state, a second capacitor C3 executes the discharging operation. Thus, charge quantity Q3 becomes zero. Consequently, reference voltage VM being the potential of the (-) input terminal side of the hysteresis comparator 11 is boosted to a potential Vref with a prescribed time constant.

Title: Grinding device for conductive roll in continuous electroplating line
Inventor: KARIYASU TAKAHIRO
IPC: C25D7/06
Filed: 1992-06-09
Abstract: PURPOSE:To appropriately grind a conductive roll by deciding the grinding power at respective position in the longitudinal direction of the roll based on grinding factors to the conductive roll and controlling the grinding power by setting the moving speed of an abrasive based on the decided grinding power. CONSTITUTION:The steel strip A is continuously plated by the conductive roll 1. The roll 1 is ground by the abrasive 9 held by an abrasive holding body 4. A screwed axis 5 parallel to the roll 1 is joined with the holding body 4 by a screw connection and the holding body 4 is moved by the rotation of the screwed axis 5. Based on grinding factors to the roll 1, increase and decrease of the grinding power at respective position of the roll 1 are decided. When the moving speed of the abrasive 9 is reduced, the contact time of the abrasive with the roll 1 is prolonged and consequently, the grinding power is increased. When the moving speed of the abrasive 9 is increased, the grinding power is decreased. By controlling the moving speed of the abrasive 9 in the longitudinal direction of the roll 1, the grinding power to the roll 1 is appropriately controlled.

Abstract: PROBLEM TO BE SOLVED: To prevent core dislocation of a drive shaft at the time of lowering and contrive promotion of mixing and agitating of soil and a hardener by discharging the hardener at a place excavating ground downward, and agitating and forming a column-like bonding part in the ground. SOLUTION: When a rotating drive shaft 1 is vertically lowered in soft ground 10, part of the ground 10 is excavated by action of an excavation wing 2. At this time, excavated soil 11 is left in an excavation hole, and a lever 6 receives the pressure of the soil from downward at the time of excavation by the excavation wing 2. Next, the drive shaft is lowered in a state in which an edge is lifted upward, and centripetal force acts as a reaction force on each lever 6. Therefor, part of vertical force is horizontally scattered and stabilized, and the core of the drive shaft 1 is stabilized to prevent core dislocation at the time of excavation lowering. At the same time, the soil 11 is vertically finely cut to promote agitating by the lever 6.  However, the two levers 6 are used and vertically fluctuatingly attached to a lever attaching fitting 7 between a horizontal position and an upward 20-40 angles inclined position respectively.

Filed: 1994-07-27
Abstract: PURPOSE:To conduct reproduction of the satisfactory direct read after write data without being affected by amplitude levels by forming a non-pit part and a recording pit part adjacently at the time of recording data and correcting the phase deviation of a clock reading out data from level values of both reproducing signals. CONSTITUTION:At the time of recording data to a DRAW(direct read after write) area, a recording bit string generating circuit 11 forms the recording pit part and the non-pit part having consecutive bit strings in a part of DRAW data with a prescribed interval. At the time of reproducing data, reproducing signals of center parts of the non-pit part and the pit part and of a boundary part between them are respectively sampled with S/H circuits 13 to 15 in a timing from a timing generating circuit 19 and then the mean value V4 between levels V1, V2 of respective pit centers is obtained by an adding circuit 16 and a multiplying circuit 17. A variable delay circuit 9 outputs a clock 3 by adjusting the delay quantity of a clock 1 so that a differntial signal 203 between V4 and the output value V3 of the S/H circuit 15 becomes zero and forms a control loop so that V4 and V3 becomes equal. Thus, a clock 4 whose phase is zero is obtained to be supplied to an A/D conversion circuit 4.

Title: Optical pickup device and its manufacture
Inventor: OKUMA HIDEO
IPC: G11B7/085
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of skew of an objective lens and to satisfactorily read out the information signal from an optical recording medium by positioning the working point of electromagnetic force of a driving coil to a position corresponding to the center of gravity of a movable part. SOLUTION: In such a state that a tracking driving current is not supplied to a tracking driving coil 24, the movable part is positioned at such a position that the working point C of the electromagnetic force (f) exerted to a focusing driving coil 23 from a magnetic circuit corresponds to the center of gravity G of the movable part as to the Y-axis direction against a base part 1, that is, such a position that the distance ΔY between the working point C and the center of gravity G of the movable part becomes 0. As the result, since the angular moment is not generated when the electromagnetic force (f) is impressed on the working point C, the movable part does not be rotated against the base part 1, then the skew on the objective lens 21 is not generated.

Title: Tape recorder
Inventor: MIKURIYA MAKOTO
IPC: G11B15/675
Filed: 1981-10-31
Abstract: PURPOSE:To avoid the burning of a solenoid, by delivering the electric signals to eject a cassette as well as to cut off a power supply in case the solenoid conduction time exceeds the set value. CONSTITUTION:A transistor TR1 is turned on and off by the input signals of an input terminal 6 of the input side and controls the conduction from a power supply terminal 7 to a solenoid 2. An arithmetic circuit 3 monitors the collector voltage of the TR1 and detects the state of conduction of the TR1. When the collector voltage of the TR1 is set at 0, that is, the solenoid 2 conducts, a prescribed positive integer K is stored in the address of a memory 4. Then 1 is subtracted every time the solenoid 2 conducts continuously for the prescribed T seconds. When the integer K is set at 0 (KT seconds later), the signals are applied to an ejection mechanism driving circuit 5 to eject a cassette as well as to cut off the power supply. Thus the burning of the solenoid 2 can be eliminated.
