Title: Fan motor
Inventor: ISHIZUKA TADASHI
IPC: F04D29/38
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce noise by providing a plurality of spherical concave portions of a predetermined size on the fin surface of the impeller such that the turbulence of the discharged airflow is reduced, and thus reducing the air resistance at the discharge portion. SOLUTION: A plurality of spherical concave portions c having diameters of approximately 0.5 mm to 3 mm, and depth of approximately 0.2 mm to 1 mm are provided on surfaces of each fin b of an impeller portion 5. Generally, when air parts from a spherical surface, turbulence acting as an air resistance is generated. The amount of turbulence generated is smaller when a separation point is located toward the back. By providing the spherical concave portions c on the fin b surface of the impeller 5, the separation point is pushed back, which narrows down a range of a turbulent swirl at the air discharge portion. Accordingly, a turbulent flow acting as the air resistance is reduced.  As described above, providing a plurality of spherical concave portions c having diameters of approximately 0.5 mm to 3 mm and depth of approximately 0.2 mm to 1 mm narrows down the separation point at which turbulence of airflow by swirl on the surfaces of each fin b is generated, reducing air resistance, and thus reducing noise.

Title: Differential amplifier circuit
Inventor: YAMAGUCHI AKIRA
IPC: H03F1/32
Filed: 1982-12-10
Abstract: PURPOSE:To increase the range of input voltage and at the same time to reduce the voltage of a power supply by setting attenuators at the reverse and non- reverse inputs of a differential amplifier to reduce substantially the amplitude value of input voltage and then deciding a working point. CONSTITUTION:A resistance R1 is put between the reverse input (-) of a differential amplifier OP and an input terminal V1, and the input (-) is connected to power supplies VDD and VSS via resistances R2 and R3 respectively. While a resistance R4 is put between the non-reverse input (+) of the OP and an input terminal V2, and at the same time resistances R5 and R6 are put between the input (+) and power supplies VDD and VSS. An input signal is attenuated by an attenuator A even though the amplitude of the input signal is large and reaching a non-linear region, and therefore the input signal can be changed within a range of good linearity. Thus, good linearity is obtained. In the same way, it is possible to have actuation at a good linearity part in a wide range of input voltage even in case the level of the power supply voltage is reduced in order to reduce the voltage level.

IPC: H01L21/768
Filed: 1984-10-16
Abstract: PURPOSE:To obtain wiring metals, which are stable even through heat treatment after forming the wiring metals and have excellent heat-resisting properties, by shaping each electrode onto a GaAs substrate and forming the multilayer wiring metals containing W onto these electrodes. CONSTITUTION:Source-drain ohmic electrodes 13 and a gate Schottky electrode 14 are shaped onto an active layer 12 in a GaAs substrate 11. A first wiring 15 and a second wiring 17 containing W are formed while interposing an inter- layer insulating film 16. W represents a high melting-point metal, and has excellent heat-resisting properties, thus maintaining initial wiring structure up to a high temperature. Accordingly, even when the temperature of the substrate 11 is brought to a high temperature in order to shape the layer 16, the increase of FET characteristics, particularly, source parasitic resistance, can be prevented after forming the wirings 15 and 17.

Abstract: PURPOSE:To obtain a waveguide layer consisting of a flat face by forming a mask having a stripe-like opening part in parallel to the semiconductor substrate <011> direction, and forming the waveguide layer by selective epitaxial growth by using said mask. CONSTITUTION:First of all, on a GaAs (100) substrate 101, a ZnS layer 102 which becomes a clad layer of the lower part is brought to epitaxial growth, and subsequently, SiO2 105 being a mask material is deposited.
