Patent JP-H04165971-A (JP)
Title: Actuator
Inventor: SAITO SHUICHIRO
IPC: H02N2/00
Filed: 1990-10-30
Abstract: PURPOSE:To realize miniaturization by controlling an applying electric field so that the torsional deformation rate of an electromechanical conversion element, forming a torsional deformation on the axial end face upon application of the electric field, is differentiated. CONSTITUTION:When a voltage to be fed on a lead wire 5a to a piezoelectric element 5 rises B in a very short time, the piezoelectric element 5 distorts abruptly and a frictional board 6 rotates abruptly in the direction of an arrow B. At that time, a rotor 2 stays in standstill. When the voltage is varied from C to A with falling D slower than the rising B, frictional force between a frictional sheet 7 and an end face 2c causes distortion of the piezoelectric element 5 in the direction of an arrow A and the frictional board 6 rotates in the direction of the arrow A thus driving the rotor 2 in the direction of the arrow A. Upon finish of distortion of the piezoelectric element 5, i.e., when the voltage returns to point A, rotation of the frictional board 6 stops abruptly thus stopping rotation of the rotor 2. The operation is repeated and the rotor 2 is driven in the direction of the arrow A.

Abstract: PURPOSE:To realize a high-speed and high-reliability LSI having an SOI(silicon- on-insulator) structure by a method wherein, after specific ions have been implanted into a single-crystal Si substrate, a heat treatment is executed and a CaFe2 crystal which has been buried in the Si substrate is formed. CONSTITUTION:<40>Ca<+> ions and <19>F<+> ions are implanted into a single-crystal Si substrate 1 by an ion implantation operation. A layer 3 into which Ca and F have been buried is formed; when the ions are implanted at a low temperature, an amorphous layer 4 is formed. An Si layer 5 on the surface is made amorphous. After that, the amorphous layer 4 is solid-grown by a heat treatment; the single-crystal Si thin film 5 is formed on the CaF2 insulating single crystal 3 containing Si. Although a defect layer 6 exists under an amorphous/ single-crystal interface (an a-c interface), the solid-grown region 4 becomes defectless. After that, an element device is formed in the single-crystal Si thin- film layer 5; then, an LSI having an SOI structure is completed. When Sr ions or Ba ions or 8 combination of them and F ions are implanted, the same effect can be obtained.

Title: Multi-beam antenna
Inventor: IWATA RYUICHI
IPC: H01Q19/185
Filed: 1986-12-09
Abstract: PURPOSE:To constitute a multi-beam antenna with high efficiency by selecting the shape of a curved face of each radiation region to be a paraboloid of revolution nearly equal to a paraboloid of revolution being a curved face of the radiated region in the case of one major reflection mirror provided to one radiated region. CONSTITUTION:If the curved face of the main reflection mirror 1 is concident with the paraboloid of revolution A', then a ray radiated from a focus Fa is reflected in the main reflection mirror 1 and is in parallel with a center axis Za (radiation direction of beam A). If the curved face of the main reflection mirror 1 is coincident with the paraboloid of revolution B', a ray radiated from a focus Fb is reflected in the main reflection mirror 1 and is in parallel with the center axis Zb (radiation direction of beam B). Thus, the curved face of the main reflection mirror 1 is decided in a way that the curved face is nearly coincident with the paraboloid of revolution within the radiated region A except the overlapped part alpha and nearly coincident with the paraboloid of revolution B' within the radiated region B except the overlapped part alpha and the overlapped part alpha is subjected to gradual transition from the paraboloid of revolution A' to the paraboloid of revolution B'. Thus, the multi-beam antenna radiating a radio wave in two different directions as shown in center axes Za and Zb is realized.

Abstract: PURPOSE:To obtain a margin for a trouble in a ROM to be divided by an address signal by writing the same bit pattern, to which a parity bit is added, to the respective address areas of the ROM. CONSTITUTION:A ROM 6 is divided into two address areas 61 and 62, and the same bit pattern, to which the parity bit is added, is stored in these areas 61 and 62. When a seizing signal is inputted from an external part through a signal line 12, data on the ROM 6 are successively read from start addresses set by the seizing signal. The data and the parity bits of the read respective addresses are checked at a parity checking circuit 7. Here, even though the trouble occurs in the ROM 6, and a parity error occurs in one address area, a normal timing signal can be generated using the other address area by changing the value of an address signal from an address selecting circuit 1. Namely, the title device can be operated without exchanging the troubled ROM 6.
