Title: Piezoelectric element structure of transducer
Inventor: OMURA MITSUO
IPC: H04R17/00
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To prevent lead wires from being disconnected, even if cavitation occurs when large power is applied by molding a casing inner wall face with a molding member and embedding the lead wires into the molding member. SOLUTION: Rectangular piezoelectric elements 2 are arranged and constituted into a cylindrical form. In the piezoelectric element 2, electrodes 3 made of silver, etc., are tangent-polarized to one end side and are arranged. The inner wall face side of a cylinder is molded by a molding member 4. Furthermore, the electrodes 3 are alternately mutually connected by lead wires 5 on the inner wall face side of the cylinder. In the piezoelectric element structure, the lead wires 5 are held by the molding member 4 by running in, setting and molding the member 4. Namely, the lead wires 5 are embedded in the molding member 4. Thus, generated cavitation collides with the molding member 4 and disappears, even if cavitation occurs when large power is applied to the piezoelectric element 2 via the electrodes 3 at transmitting in this piezoelectric element structure.

IPC: G01B21/26
Filed: 1984-08-03
Abstract: PURPOSE:To detect the toe of a wheel accurately and speedily by calculating a straight line which divides internally the interval between couples of front and rear wheels of a vehicle at the same ratio, detecting the inclination of it to a reference line and also detecting the degrees of inclination of the respective wheels, and making corrections on the basis of the inclination. CONSTITUTION:Couples of front and rear wheels of the vehicle are placed on a conveyance plate 4AR. Further, a pantagraph 5A is provided between the couple of front wheels and the direction is detected with an indication rod 9. Similarly, the direction is detected between the couple of rear wheels with an indication rod. The indication rod 9 between the front wheels is set in the same direction with the indication rod between the rear wheels and the straight line which divides internally the interval between the wheels at the same ratio is calculated to detect the degree of inclination to the reference line. Then, the wheels are sandwiched between detection plates 14a from both sides and the degree of inclination of the toe of the wheels is detected from the direction of an indication rod. Then, the degree of inclination of the toe is corrected with the degree of inclination of the straight line to the reference line to detect the degree of toe inclination. Therefore, the degree of the toe inclination is only corrected to measure the degree of inclination of the wheels accurately.

Abstract: PROBLEM TO BE SOLVED: To reduce the influence of the collision of vehicles by adjusting a vehicle height so that a collision energy is efficiently absorbed. SOLUTION: In this device, the image information of the front side rear side of a vehicle is analyzed (S20, 80) to decide whether or not a preceding or following vehicle is present (S30, 90). Upon decision of an affirmation, the outline of another vehicle is specified and the relative speed of another vehicle to a self-vehicle is calculated based on the change speed of the size of the outline of another vehicle (S40, 100). Then, it is decided whether or not a front collision or a rear collision may be highly possibly generated based on the relative speed and the speed of the self-vehicle (S50, 110). Upon decision of an affirmation, the height of a rear bumper or a front bumper is estimated based on the outline of another vehicle (S60, 120).  A vehicle height is adjusted so that the front bumper or the rear bumper of the self-vehicle has the height substantially the same as that of the rear bumper or the front bumper of another vehicle (S70, 130).

Title: Starting device for long arc lamp
Inventor: KOBAYASHI SHIGENORI
IPC: H05B41/18
Filed: 1993-06-10
Abstract: PURPOSE:To enable a lamp re-lighted instantaneously after lighting off by applying a commercial AC to both ends of a bypass capacitor, turning two thyristers on alternately in accordance with the polarity of an AC power supply, and generating starting pulses to a high voltage pulse generating transformer. CONSTITUTION:In a low voltage side discharge circuit of a high voltage pulse generating transformer PT, when a thyrister S1 is turned on near a positive peak value of an AC power supply E, a quick discharge current flows through a closed circuit on the right side of a bypass capacitor CP. At this time, an induction current is generated because of inductances such as L1, L2 in the discharge circuit, and when the discharge current becomes zero, the current starts flowing in an inverse direction in the closed circuit. However, because the thyrister S1 prohibits the current, a negative voltage is generated at capacitors C1, C2. Next, by putting on a thyrister S2 close to a negative peak value of the power supply E, the same phenomenon occurs in the opposite direction. By repeating this, a discharge voltage can be set twice or more of the power supply voltage peak value.

Title: Detection for deffective memory transistor and its detecting device
Inventor: KOROGI YASUHIRO
IPC: G11C17/00
Filed: 1994-07-15
Abstract: PURPOSE:To detect a low Vth memory cell in an erasing state by selecting all rows by voltage of a non-selection row or lower voltage than Vth of a memory FET in which electrons are already discharged from IG at the time of a test, and reading out by adding higher voltage than that at the time of read-out to a selected column. CONSTITUTION:When a bit line BL1 is selected by a signal CS in an erasing state in which all memory cells are normal, a potential of FG comes to a potential based on capacity coupling of the FG and a drain, this potential is far lower than a potential by which Q is turned on, a drain current IM is a sense current or less, and a sense amplifier is judged as 0V, that is, normal. When only Q11 is defective, a potential of the FG is indicated as BL1 is 0V, for example, 0.5V. When 2V is applied to a drain through the BL1, a potential of the FG is raised and the Q11 is turned on, IM exceeds a sense current, the sense amplifier 30 is judged as abnormal. The higher BL voltage at the time of test read-out is raised, the more detecting sensitivity are increased. Concerning a soft line, since a word line WL at the time of a test is non- selection and is finished to detect by one time read-out, considering its influence is not required.

Abstract: PURPOSE:To suppress the influence of parasitic vibration generated in a vibrator and to improve the signal-to-noise ratio by specifying the shape of the contour of an electrode printed on a single-crystal piezoelectric vibrator. CONSTITUTION:The single-crystal piezoelectric vibrator 2 is coated with couplant and pressed against a metallic material to be inspected for defect detection, etc. Then an electric signal which is transmitted through a cable 15 is fed to an electrode 3 and the material to be inspected which constitutes the other electrode and the vibrator 2 after impedance matching is energized to vibrate in specific mode in its thickness direction, so that the ultrasonic probe radiates an ultrasonic wave.
