Title: Semiconductor integrated circuit device and its manufacture
Inventor: ITO YASUSHI
IPC: H01L27/04
Filed: 1997-06-14
Abstract: PROBLEM TO BE SOLVED: To provide the manufacturing method of a semiconductor integrated circuit device, which facilitates the flattening of an interlayer insulation film formed on a MOS transistor and capacitor formed on the same semiconductor substrate by making their heights identical with that each other. SOLUTION: Forming an oxide film 11 on a semiconductor substrate 20, whose thickness is made large and different from the one of a gate oxide film 8 of a MOS transistor formed on the same substrate 20, an impurity with the extent of an amount of generating no breakdown in the film 11 is injected into the portion just below the film 11, to form a MOS capacitor with a small voltage factor. In this case, making respectively the layers constituting electrodes 12, 14, 15 of the MOS capacitor identical with the layers constituting gate electrodes 9, 14, 15 of the MOS transistor, the heights of both the electrodes are made respectively identical with each other. A highly precise capacitor is formed, without changing any performance of the MOS transistor formed on the same semiconductor substrate 20.  By making the heights of the MOS transistor and capacitor identical to each other, the planarization of an interlayer insulation film 18 formed on them is facilitated.

IPC: G02B6/12
Filed: 1987-07-13
Abstract: PURPOSE:To increase an angle of branching and to enable size reduction and integration by arranging a low-refractive-index layer whose thickness and refracting index are specified at the intersection part of two optical waveguides at an angle where the layer bisects the angle of the intersection and the section crosses the optical paths of light signals in optical waveguides. CONSTITUTION:Optical waveguides 5a and 5b, and 6a and 6b consisting of cores 3 and clads 4 are arranged crossing each other, and the low-refractive-index layer 8 is arranged at the intersection part 7 at the angle where the layer bisects the angle of the intersection and its section crosses at least part of the optical paths of light signals. The thickness of the layer 8 is nearly equal to or smaller than the wavelength of signal light in a medium and the refractive index is lower than those of the optical waveguides 5a and 5b, and 6a and 6b. Then 1st light input 9 inputted from the optical waveguide 5a is reflected partially by the low-refractive-index layer 8 and propagated to the optical waveguide 6b as a 2nd light output 10. The thickness (d) and refractive index of the low-refractive-index layer 8, on the other hand, are selected properly and then the 1st light input 9 is branched to the optical branch waveguides 5b and 6b. Consequently, the angle of branching is made large and the size reduction and integration are enabled.

Title: Ultrasonic motor
Inventor: NISHIKURA TAKAHIRO
IPC: H02N2/00
Filed: 1988-07-12
Abstract: PURPOSE:To lengthen the lifetime of a motor and to improve its reliability either by keeping trapezoidal inclination to a projected body of an oscillating body in the circumferential direction or in the diametrical direction, or by keeping curvature to the contact surface of the projected body with the frictional material. CONSTITUTION:An oscillating body 22 of a disc type ultrasonic motor is composed of an elastic body 20 and a piezoelectric body 21. On this occasion, projected bodies 23 are provided to the oscillating body 22 which have trapezoidal inclinations in the circumferential direction. The width of the vertex of each trapezoidal projected body 23 therefore becomes narrow, so that the contact state of a friction material with the trapezoidal projected body 23 is always constant. There will be no scratch caught by the angles of the projected body 23 even in a low speed rotation and the motor can rotate stably. Flexural rigidity can also be reduced. By the way, a projected body 23 may have a trapezoidal inclination in the diametrical direction or may have a curvature to the contact surface with the friction material.

Title: Multistage connection switch network
Inventor: ISHIBE MANABU
IPC: H04Q11/04
Filed: 1989-07-07
Abstract: PURPOSE:To prevent crosstalk or deterioration in the high speed transmission characteristic due to wiring by employing an integrated circuit for wiring between switches to eliminate the need for cross wiring. CONSTITUTION:For example, a 2-input 2-output switch is employed as a unit switch 1. Then 8 unit switches in the longitudinal direction and 4 unit switches in the lateral direction, in total 32 unit switches are mounted on one board 3 as a whole to constitute a multistage connection switch network with 16-input and 16-output. Moreover, the 8 unit switches in the longitudinal direction are configurated as one module and the wiring for each module uses an integrated circuit 4. Moreover, the unit switches are used for 2-input 2-output application by internal selection in the unit switches properly. Since a multi-layer wiring with excellent transmission characteristic in general is facilitated by the circuit integration technology, high speed transmission is attained. Furthermore, when the data speed is very fast, there might be a problem in crosstalk in the integrated circuit 4. The problem like this is solved by using differential transmission signals through the integrated circuit 4.

Abstract: PURPOSE:To make the titled cartridge compact by providing a hole for a clamper bridging from a plane surface part of the upper half and the lower half of a cartridge to the side wall part thereon, and providing a turntable and a hole for a head on other lower half and an upper half. CONSTITUTION:A space between an upper end of a turntable 5 and a lower end of a clamper 6 is smaller than a thickness (h) of a cartridge 2. When the cartridge 2 is moved toward a direction shown by an arrow A, the clamper 6 passes through a part 251A of a side wall part and enters the cartridge. The turntable 5, similarly, passes through a part 251B of the side wall part, enters the cartridge and stops at a position coinciding with a central hole 3A of a disk 3. A space between the upper end of the turn table 5 and the lower end of the clamper 6 is determined by a net thickness (t) of the disk 3 and allowances (n) and (p) for stably inserting the cartridge into the space between the turntable and the clamper, so that it can be made very narrow. A lowering distance of the clamper 6 is H2-t and can be made small. Thereby, a compact and simple disk device can be obtained.
