Inventor: NAKAJIMA MIKIO
IPC: H01L41/257
Filed: 1993-03-04
Abstract: PURPOSE:To provide a method for partially polarizing a piezoelectric element component in which a defective product occurrence rate due to a crack caused by a stress concentration in the vicinity of a boundary between a polarized part and an unpolarized part can be reduced and which can obtain the component having excellent reliability. CONSTITUTION:Polarizing electrodes 12, 13 are partly formed on both main surfaces of a piezoelectric plate 11, and have a part having a wide gap and a part having a small or no gap so as to form gap regions in which ends are not superposed to one another. A method for partially polarizing a piezoelectric element comprises the steps of applying a DC voltage between the electrodes 12 and 13 to polarize superposed regions of the electrodes 12, 13 concentrically generating a crack at the piezoelectric element in the part having the wide gap, and removing the element having the crack after the polarization.

Abstract: PURPOSE:To make variations in a base air-fuel ratio of a carburetor absorbable, by installing a suction control valve in a suction system and a secondary air control valve in an exhaust valve respectively, while monitoring the level of a driving signal of each valve, and controlling the generating timing of this signal. CONSTITUTION:Pipes 58 and 60 forming an air bleed passage are connected to air intake ports 54 and 56 installed in a housing 52 forming a float chamber 38 for a carburetor 16, and each of these pipes 58 and 60 is connected to a suction control valve 62. In addition, a secondary air control valve 74 is connected to an exhaust manifold 20 via air suction pipes 76 and 78, and this valve 74 is controlled by a controller 66 together with the suction control valve 62. At this juncture, at the time of air-fuel ratio feedback controlling, the level of a driving signal is monitored, and when an air-fuel ratio shifts to the rich side with a rise in the level, the generating timing of the driving signal is quickened, but when the air-fuel ratio shifts to the lean side with a level drop, the generating timing is controlled so as to be delayed to some extent.

Abstract: PURPOSE:To reduce the possibility of noise entering to another line accommodated in a same cable as a line with a ringing signal sent therethrough considerably by applying on/off control to a circuit sending the ringing signal based on a clock pulse synchronously with the period of the ringing signal. CONSTITUTION:When a main control section 14 receives incoming information, the section 14 sends a drive command to turn on or off a relay mechanism 12 at a predetermined period to a relay control circuit 13. When the relay control circuit 13 is commanded from the main control section 14 to turn on or off the relay mechanism 12, the relay mechanism is subject to on or off control synchronously with the leading of a clock pulse CP fed from a synchronizing signal output circuit 4. When the relay mechanism 12 is in ON or OFF operation, a timing of an output voltage of a ringing signal output circuit 3 is always 0[V]. Thus, noise entrance is considerably decreased to another lines accommodated in a same cable as a line through which the ringing signal is sent.

Then, a P-type base region 2 is formed at the inside of the P-layer 5. In addition, when an N-type cathode region 1 is formed, an N-type impurity is diffused also to an outer peripheral part on the rear; an N<+> type region 6 is formed; a concentration value of an N-type impurity in this part is increased; an ohmic property of a rear electrode is improved. Lastly, a cathode electrode 9 and an anode electrode 10 are formed. A Schockley diode formed in this manner is a diode whose outer peripheral part is reversely conductive. When it is used as an element for ignition circuit use, it is not required to additionally install a diode to be attached externally.

Title: Positioning mechanism for oscillatory magnetic head
Inventor: MATSUMOTO HIROSHI
IPC: G11B5/54
Filed: 1984-03-09
Abstract: PURPOSE:To stabilize positioning operation by aligning the position of a rotary center shaft to a center position of an impact to the center of gravity of a magnetic head and the whole oscillation part. CONSTITUTION:The rotary center shaft 3 is so arranged that xS=xG+I/MXG, where M is the total mass of the oscillation part consisting of the magnetic head 1, a head arm, the rotary center shaft 3, and the movable part 5 of a driving motor, I is moment of inertia, and (xG, 0) and (xS, 0) are coordinates of the center 8 of gravity and the rotary center shaft 3. Consequently, the rotary center shaft 3 is aligned to the center of the impact and a core gap 7 is held in a stationary state. Namely, when force F(t) operates on the rotary center shaft 3 in the direction of a (y) axis 10, the kinetic equation of the center 8 of gravity in the direction of the (y) axis 10 is as shown by I, where yG is fine displacement. When time t is 0 and initial displacement and an initial speed are also 0, an equation II holds. The kinetic equation in the rotational direction around the center of gravity, on the other hand, is as shown by III. When time t is 0 and an initial rotation angle and an initial angular speed are 0, an equation IV holds. Therefore, when the fine displacement of the core gap part 7 in the direction of the (y) axis 10 is denoted as yH, theta is considered to be fine, so an equation V holds. However, yH=0 because xS=I/MXG+XG.

Abstract: PURPOSE:To enable a clear observation of the shape of the cross-section of a sample by recessing or protruding a metal thin film deposited on the observing surface of a sample intended for observing the shape of the cross-section from the cut section of a bed of the sample to form a step along the shape of the cross-section of the observing surface. CONSTITUTION:After a metal thin film 8 is deposited on the observing surface 6 thereof, a sample 5 for an electron microscope is embedded into a bed material 9 such as resin metal to form a bed body 10. Then, the bed body 10 is cut off at the plane crossing at the right angle to the observing surface 6 and the cut section 6 is ground to expose the sample 5. The bed body 10 is emmersed in a corrosive agent adapted to corrode the thin film 8 alone to form a concave on the cut section. When the sample and the bed material are non-conductive, a conductive thin film 11 is bonded on the cut section of the bed body 10. The sample 5 and the bed material 9 are corroded to form a convex on the thin film 8 in stead of the corrosion of the thin film 8. Thus, a step is formed along the shape of the cross-section to add a contrast thereby enabling a clear observation.
