Title: Manufacture of lead titanate-zirconate fan column-urethane rubber star-type composite piezoelectric element material
Inventor: OHARA KEISHIN
IPC: H01L41/45
Filed: 1988-09-05
Abstract: PURPOSE:To obtain one capable of vibrating only in a direction vertical to the end surface without vibrating in a direction parallel to the end surface of a fan column when an AC voltage is applied by a method wherein an auxiliary substrate is bonded to the end surface of a cylinder of PZT on which polarization is performed. CONSTITUTION:After polarization in a direction vertical to the circular surface of the end surface is performed on a cylinder 1 of lead titanate-zirconate (PZT), an auxiliary substrate 2 is bonded to the end surface of the PZT cylinder 1 to form a PZT cylinder-auxiliary substrate composite. Next, two or more cut grooves 4 intersecting at the same angle in the line connecting the centers of the circular surfaces and reaching its circumference are formed on the PZT cylinder-auxiliary substrate composite cylinder 1 and the PZT cylinder is divided into fan columns 11 to 14, forming a PZT fan column-auxiliary substrate composite. Then, the PZT fan column- auxiliary substrate composite cut groove 4 is filled with urethane rubber 5. After it is hardened, the auxiliary substrate 2 is removed and a PZT fan column-auxiliary substrate star type composite piezoelectric element material is formed.

Title: Manufacture of semiconductor device
Inventor: YOSHINO CHIHIRO
IPC: H01L29/732
Filed: 1992-08-19
Abstract: PURPOSE:To reduce the element isolation area, the element area and the parasitic capacitance by forming a shallow groove in order to isolate the element regions, capping the upper surface of a filling material for a deep groove and filling up the shallow groove with an insulator. CONSTITUTION:A deep groove 52 is formed in a semiconductor substrate 50 and an insulating film 53 is formed on its surface. On the surface of the insulating film 53, a filling material 54 is deposited and is then etched back in such a way as to leave the filling material 54 inside the deep groove 52. Next, the insulating film 53 is patterened to form a mask for a shallow groove. An anisotropic etching of the semiconductor substrate 50 is effected using the mask, so that a shallow groove is formed. Next, the insulating film 53 projecting upward from the surface of the semiconductor substrate 50 is removed and an insulator 55 is deposited over the whole surface, followed by etching back to leave and burry the insulator inside the shallow groove, and thereby an element is formed in an element region. Thus, element isolation characteristics do not deteriorate and also the parasitic capacitance can be reduced.

Title: Irradiation system for electron ray device
Inventor: YANAKA TAKASHI
IPC: H01J37/10
Filed: 1984-10-22
Abstract: PURPOSE:To image an electron probe of minute diameter without performing any complicate control or operation by locating the final stage lens of four focusing lenses near a front objective and adjusting the synthetic reduction rate to below a given level. CONSTITUTION:Four focusing lenses (C1-C4) are installed between an electron ray source and a front objective (L1). The final stage lens (C4) is placed immediately in front of the front objective (L1). The synthetic reduction rate is adjusted to be 1/30 or lower. The diameter of an image (P1) located 130mm. apart from the lens (C1) is 1,000nm which is then reduced with the lens (C2) into 40nm that is the diameter of an image (P2). Following that, the image (P2) passes through the lens (C3) without being reduced in the size to produce an image (P3) which is then reduced into 1/20 by means of the lenses (C4) and (L1), thereby imaging an electron probe of 2nm diameter on a sample (Q). Therefore, when the electron probe is not accurately imaged on the sample (Q), controlling can be performed only by changing the focal distance of the third stage focusing lens (C3). Accordingly it is possible to perform rapid operation of an irradiation system for an electron ray device.

Title: Wheel
Inventor: OKADA TOKUJI
IPC: B60C7/08
Filed: 1982-12-16
Abstract: PURPOSE:To reduce horizontal stress and enable horizontal tumbling in a wheel with a tire section for a car and such by comprising a part of the circumferential direction of the tire section with a rotary partial tire around a rim. CONSTITUTION:A tire section 8 is divided comparatively finely in the circumferential direction and duplicate partial tires 4 and 5 are comprised as an aggregate. The partial tire 5 can be rotated in the R direction around an axis A that is almost in parallel to the tangent direction of a wheel rim 3 for the wheel rim 3. The tire section 4 uses a fixed partial tire. As a result of this structure, when the fixed partial tire 4 is grounded, it can be run like a normal wheel, but when the rotary partial tire 5 is grounded, the rotary partial tire 5 rotates and absorbs horizontal external force if it is applied. As a result, horizontal external force can be reduced and horizontal tumbling is enabled in a unit.

IPC: H01S3/137
Filed: 1988-09-05
Abstract: PURPOSE:To provide the solid etalon which can maintain excellent optical characteristic prior to irradiation even under irradiation of laser light by using a material which is negative in the temp. coefft. of a refractive index and is higher in thermal conductivity than quartz as a transparent parallel plane substrate material. CONSTITUTION:Coating layers (reflection films) 12 which consist of multilayered dielectric films and are equal in reflectivity are formed on both surfaces of a transparent substrate 11. A material which is negative in the temp. coefft. of the refractive index and is higher in the thermal conductivity than quartz is used as the material of the transparent substrate 11. The refractive index in the central part where the temp. is high is smaller than the ambient refractive index and a concave lens effect is obtd. if the temp. coefft. of the refractive index of the material constituting the transparent substrate 11 is negative. Since this concave lens effect and the convex lens effect by the thermal expansion negative each other, the spacial uniformity of the optical path in the substrate is eventually maintained. The excellent optical characteristics prior to the irradiation are, therefore, maintained even under irradiation of the laser light.
