Title: Surface acoustic wave device
Inventor: NAKAKOSHI ARATA
IPC: H03H9/02
Filed: 1984-01-11
Abstract: PURPOSE:To decrease the leakage loss flowing out of both ends of a substrate by arranging repetitively the units of input/output transducers. CONSTITUTION:Each input/output transducer (TR) is divided into two and each output TR is arranged at both sides of each input TR. In considering the leakage loss only, when the electrode finger number is equal to the two input TRs T5, T8, the signal applied to an input terminal 4 is shared uniformly and becomes -3dB to the input. Thus, the surface wave of -6dB is excited at both sides of each input TR. Since the TRs T4, T9 at the outside receive signal from one side only, the output is -9dB and the power of -9dB is leaked to the opposite side. The output T of the center is -3dB and the output of the output TRs T6, T7 is -6dB and an output power of -4.3dB in total from output terminals 5, 6 is obtained. Thus, the leakage loss is improved by dividing each input/output TR into two.

IPC: B60Q1/28
Filed: 1985-01-10
Abstract: PURPOSE:To facilitate fitting and prevent the breakage by the rotary mop of an automatic car washer by pivotally supporting an indicator body erectably and foldably on a base stuck on a front fender. CONSTITUTION:A light transparent plate 8 with its one-side surface roughly machined as a light diffusion operation surface is arranged in the middle area of a columnar body made of transparent resin of an indicator body 2. The other side surface of the indicator body 2 is covered with an outer hull 10 made of opaque resin with its center section left in a slit shape. A base 1 fitted with this indicator body 2 erectably and foldably is stuck to one or both sides of a car body bonnet so that the light diffusion operation surface faces the driver seat side when the indicator body 2 is erected. Thereby, the light from the front is focused on the light diffusion operation surface, and the driver can recognize this indicator body 2 due to the irregular reflection when the light passes this surface. Accordingly, fitting is easy and no electric cord is required, and furthermore, when the indicator body 2 is folded, it is prevented from being broken by a mop.

Abstract: PURPOSE:To effectively cover a compound semiconductor region with a desirable insulating layer by covering the top surface of a thin S layer with a metal layer at a low tsmperature, then oxidizing it to form a first insulating layer, and forming a second insulating layer thereon. CONSTITUTION:After a purified semiconductor substrate 1 is dipped in a solution of ammonium sulfide and removed, N2 (nitrogen) gas is sprayed to remove adhered solution.

When the semiconductor substrate 1 is left to stand for vacuum, and a thin S layer 3 is formed on the surface of the compound semiconductor region 2 obtained by vanishing most of the amorphous film. An Al metal layer 4 is formed on the upper face by a vacuum depositing method. When the metal layer 4 is thermally oxidized by heating, it is altered to a metal oxide layer (first insulating layer) 5 made of Al2O of an insulator. An SiO2 film 6 is formed as a second insulating layer on the top surface by a plasma CVD method or an optical CVD method. Thus, the characteristics of a semiconductor device using the compound semiconductor formed in this manner and the manufacturing yield can be improved.
