Title: Optical disk device
Inventor: HASHIMOTO MINORU
IPC: G11B7/135
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device provided with a small and thin optical pickup capable of utilizing a RF amplifier being conventionally used as it is. SOLUTION: An optical pickup 111 outputs a RF signal, a focusing error signal FE and two tracking signals E, F. The FE signal is generated by subtracting two focusing signals PDI, PD2 in an operational amplifier 71 and adjusting the signal gain in an operational amplifier 72. The RF signal inputted from the terminals 21, 22 of a RF amplifier 112 is subjected to amplification and equalization in an operational amplifier 75 and outputted. The operational amplifier 76 subtracts the RF signals inputted from the terminals 21, 22 from each other, outputs it but the output is not used. The E, F signals inputted from terminals 23, 24 are subtracted in an operational amplifier 77 and becomes a tracking error signal TE. The FE signal is inputted to a servo block 116 from the output optical pickup 111.

Title: Capacitor type converter
Inventor: HIRATA TERUTAKA
IPC: G01D5/24
Filed: 1982-10-25
Abstract: PURPOSE:To compensate for nonlinearity effectively, by using a pair of variable capacitors, whose capacity is differentially varied in correspondence with the quantity to be measured, and a reference capacitor, whose capacity is constant. CONSTITUTION:A pair of variable capacitors C1 and C2 are constituted by a movable electrode 10, which is displaced in correspondence with the quantity to be measured such as pressure, and fixed electrodes 11 and 12. The capacity of a reference capacitor C3 is constant. A capacity pulse width converting circuit C/P detects the change in capacity of the capacitors and outputs a pulse width signal PW1, whose duty ratio corresponds to the difference in capacities of the capacitors C2 and C1 and a pulse width signal PW1, whose duty ratio corresponds to the difference in capacities of the capacitors C2 and C3. A switch SW2 is driven by the signal PW2 and turns ON and OFF a preset voltage Vr. An integrating circuit IC adds and integrates a voltage, which is obtained by turning ON and OFF the voltage Vr by the switch SW2, an output voltage Vo, and a reference voltage VS1, and obtains the voltage Vr. A filter circuit FC smoothes the voltage, which is turned ON and OFF by a switch SW1 and obtains the output voltage Vo.

Abstract: PURPOSE:To enable everybody to easily breed stag beetles by putting male and female imagoes of stag beetles in a vessel containing river sand and decayed wood, letting the beetle spawn in the vessel and feeding the beetle with apple. CONSTITUTION:For example, in the case of breeding in a room, a piece of decayed wood having a size sufficient to feed a larva of stag beetle for 3 years is sterilized by boiling and put into a glass vessel containing river sand preferably having coarse mesh. A sufficient amount of water is supplied to the sand and an apple (preferably red-skin hard-texture apple) divided into two is put into the vessel as a feed. Male and female imagoes of stag beetles are put into the vessel and allowed to copulate and oviposit. The deposited egg is hatched and bred through a larva and a pupa to an imago for 3 years in a place shielded from direct sunshine.

Title: Image processor carried on vehicle
Inventor: SATO KOICHI
IPC: G06T7/00
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To obtain an image processor by which a white line can be recognized stably without being subjected to the influence of a noise which is stable in a time-series manner by deciding the white line on the basis of traffic-lane-width information from an extracted white-line candidate point. SOLUTION: In a preprocessing means 28, an image in which a contour has been extracted and which has been binalized, is subjected to time quadrature by using integration device, and an output signal by a time-quardrature means 29 is input to a region division means 30. This is performed by using a comparison means. When the signal is larger than a specific threshold, a region I is divided into two regions on a screen, and, when the signal is small, a region O is divided into two regions. Then, a deletion processing operation such as a white-line recognition operation or a vehicle recognition operation is limited to the region I. Thereby, a processing speed can be increased as a whole. Then, by using the region I, a white line is recognized by a white-line recognition means 3. When the white line is recognized, the white line inside the region I is found from its contour.  In this manner, a designated region is selected as a white-line candidate point, and the white line is decided according to every region.

Abstract: PROBLEM TO BE SOLVED: To maintain an engine output performance or exhaust emission performance so excellently by improving the extent of responsiveness at the early stage of phase alteration. SOLUTION: In time of the start of alteration in the turning angular phase of a camshaft side member at the release of a phase holding by a releasing means 16, an initial driving torque capable of altering an actual turning angular phase of this camshaft side member to the side of a target turning angular phase is given to this camshaft side member by a driving means 21, while if a variation in the actual turning angular phase of the camshaft side member is reached to the set value by phase altering motion, control over the driving torque of the driving means 21 is switched to feedback control.  With this constitution suchlike, the extent of responsiveness in the phase alteration at the early stage of alteration in a turning angular phase difference between the camshaft side member and the output shaft side member is improved high, and in addition, if any slippage of the turning angular phase is produced there, it is solved in a short time, so that an improvement in an engine output performance or exhaust emission performance is well promoted.

Title: Member for oa equipment
Inventor: TAKAGI MITSUHARU
IPC: G03G15/08
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To reduce the variance of a resistance value, to keep the stable resistance value even with respect to a change in environment and to obtain an image of high quality by providing a conductive elastic body incorporating specific carbon black and positively electrifiable fine grains. SOLUTION: When carbon black is added into a base material resin to adjust conductivity and to form a conductive elastic body 3, fine grains having positive electrifiable property are made to coexist with the carbon black whose the DBP oil absorption is <=80 ml/100 mg and the nitrogen adsorption specific surface area is <=150 m<2> /g. Consequently, a flocculating structure is brought by the mutual work between the carbon black and fine grains with positive chargeability. Then, the carbon black can be made stably present in the resin by a conductive substance having the flocculating structure.  Therefore, the resistance value can be adjusted well in a higher resistance region than that when carbon is merely dispersed in the resin and a conductive resin composition capable of eliminating the variance in such a resistance region and demonstrating stable conductivity even with respect to an environmental fluctuation can be obtained.
