Title: Laminate type piezoelectric actuator
Inventor: HAYASAKA TAMIO
IPC: H01L41/09
Filed: 1989-11-09
Abstract: PURPOSE:To enable a title actuator to follow up the expansion and contraction of a piezoelectric element by filling a small hole provided in a piezoelectric laminate a conductive resilient member instead of an external electrode. CONSTITUTION:Ag-Pd paste 3 is applied to a small hole 2 in one element 1 so as to extend to the edge of the small hole, while a blank part 5 of 3mmphi for example is provided on the other small hole 4 in a concentric member with the 1mmphi small hole 4, to which part 5 paste is applied. Further, for the rear of the element 1, a 3mmphi blank part 6 concentric with the small hole 2 on the rear side of the small hole 2 and Ag-Pd paste is printed on the rear side of the small hole 4 so as to extend to the edge of the small hole. The surface and the rear are reversed and alternately laminated and sintered under pressure. Then, a material where silver powder is blended in acryl nitrile butadiene rubber is heated until it becomes fluid, and pressed and filled into the small holes 2, 4 in a laminate sintered body via spaces. Since electrical connection between internal electrodes is achieved through a conductive resilient member 8 in such a manner, the conductive resilient member 8 can follow up the expansion and contraction of the piezoelectric element and hence the electrodes are prevented from being damaged.

Title: Anti-skid control device
Inventor: YASUNO YOSHIKI
IPC: B60T8/1761
Filed: 1994-11-24
Abstract: PURPOSE: To prevent overreducing of pressure so as to enable correct anti-skid control by suspending pressure reducing to maintain a holding state when the target pressure reducing time is less than the minimum pressure reducing time. CONSTITUTION: At the time of starting to reduce pressure, the target pressure reducing time ΔT* is computed on the basis of the wheel slip quantity and wheel acceleration-deceleration Vwi' based on the estimated body speed Vx and wheel speed Vwi (S11b). The shorter time between the target pressure reducing time ΔT* and the set pressure reducing the ΔT is set as the pressure reducing time TG (S11i). Until the lapse of the specified time TO after the lapse of the pressure reducing time TG, pressure reducing is inhibited, and a holding state is maintained (S11g), and after the lapse of the specified time TO, the minimum pressure reducing start time ΔTmin based on the elapsed time CT from the pressure reducing start time is computed (S11j).  At the time of ΔT>=ΔTmin, a pressure reducing state by the minimum pressure reducing time ΔTmin is set (S11m), and at the time of ΔT*<ΔTmin, a holding state for preventing overreducing is set (S11g). Overreducing of pressure is thereby prevented to enable correct anti-skid control.

Title: Power supply circuit for telephone set
Inventor: HARA MICHIO
IPC: H04M19/08
Filed: 1986-12-04
Abstract: PURPOSE:To reduce the ripple of a smoothing power supply by permitting other transistor to turn off the base current of a transistor when the transistor is reversely biased to attain a potential to work as a reverse transistor. CONSTITUTION:AC signals are superimposed to line terminals L1-L2. If the line terminal L1 falls below a constant voltage Vcc, the potential of the base of a transistor Q3 drops and the Q3 is turned on. The potential of the emitter of the Q3, one side of an R2 and the emitter of a transistor Q1 fall, and the Q1 and Q2 are turned off. The current of a constant-current circuit 1 flows through the Q3 and the constant-current circuit 1 is not saturated. The potential of the emitter of the transistor Q1 falls, and its potential relation comes to that the Q1 works as the reverse transistor. The base current of the Q1 does not flow since the transistor Q2 is turned off, whereby the Q1 does not work as the reverse transistor, and discharge from the power supply Vcc through the Q1 is eliminated. Thus, the current deficiency of a constant voltage circuit 3 does not occur, and the impedance of the constant voltage circuit 3 is held low, whereby ripple decreases.

Filed: 1986-12-05
Abstract: PURPOSE:To shorten and simplify a program by collectively using the group of index values in a range specified by an instruction for the formation of an effective address of the same instruction. CONSTITUTION:A base address holding means 11 holds a base address, one or more factor value holding means 12 holds factor values and an index value sequence generating means 10 generates all sequences consisting of the same number of index values as the number of factor value holding means 12 consisting of values such that the absolute values of all the values are <=an index upper limit value specified by an instruction and the absolute value of at least one value is >=an index lower limit value specified by an instruction. An effective address forming means 1 forms a value obtained by adding the inner product of the sequential vector of the index values generated by the means 10 and the factor value vector of the factor values stored in the means 12 to the base address stored in the means 11 as an effective address indicating an object to be operated by an instruction.

IPC: G11B5/41
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a tape cassette incapable of being used after the cassette is loaded by specific times or above on a video recording/reproducing device. SOLUTION: A disk 14b at the upper side of a reel 14 is freely rotatable around a rotary shaft 14a. A movable member 24 is turned by loading the cassette on the recording/reproducing device and returned to the initial state by unloading the cassette. Thereby the disk 14b is rotated by the specific angle by a pin 48 of a driving arm 40. The reverse rotation is prevented by a reverse rotation preventing arm 50. The leader part of the tape 15 at the side of the reel 14 is arranged to be longer so as to reach on the optical path of a tape detecting light 32 at the side of a reel 12 at most under the state pulled out from the reel 14. When the cassette is loaded by specific times or above, a light shielding plate 54 on the disk 14b erected facing to a disk 14c comes to the position of a sign 54b to shield the tape detecting light 34.  The tape is pulled out at most from the reel 14 by the rewinding of the tape 15. As the result, the tape detecting light 32 is transmitted through the leader part under the state when the tape is taken up to the reel 12.
