Title: Water-proof speaker
Inventor: MINE TAKAKUNI
IPC: H04R17/00
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent performance of sound quality or the like from being changed and to prevent deterioration in a diaphragm by coating a water repelling paint to the diaphragm of the speaker available in a general market and deciding the film thickness of the water repellent paint based on the water repelling performance, a sound quality change in the speaker and durability or the like to repel water from the surface of the diaphragm even when the speaker is soaked in water. SOLUTION: A water repellent paint is applied on a speaker diaphragm 1 of a piezoelectric speaker from a prescribed distance by a spray and dried naturally at room temperature for a prescribed time. When a coating film thickness of the film 2 of the water repelling paint is selected to be 40 μm or over, the water repelling effect can be obtained. The coating film thickness of the film 2 of the water repellent paint is thicker, the sound pressure of the speaker gets smaller and when the coating film thickness is selected to be 70 μm or over, the sound pressure is rapidly decreased. As the coating film thickness of the film 2 of the water repelling paint is thicker, the durability of the speaker gets higher, but when the coating film thickness is selected to be 50 μm or below, the durability is rapidly deteriorated.  Thus, the coating film thickness of the film 2 of the water repellent paint is properly selected within a range of 50-60 μm.

IPC: G06F9/455
Filed: 1994-12-27
Abstract: PURPOSE: To detect a part to be the bottle neck of performance by precisely analyzing the operation of a computer at the time of application execution. CONSTITUTION: A system call function model 11 stores the operation model of a system call part as the function of an OS. The operation model is expressed by an executing instruction sequence in the case of executing each system call. When an argument is accompanied at the time of system call, the operation model is described with the argument as a parameter. A system call analysis module 12 detects the system call part from the instruction sequence just under execution by an execution application 101, extends/adds the system call to the executing instruction sequence while referring to the system call function model 11 and outputs an extended instruction sequence 103. Concerning the extended instruction sequence, the system call part is also extended to the executing instruction sequence, and the reference relation of instructions to be executed is solved at all.

CONSTITUTION: An SAW delay oscillator 1 wherein a part of a transfer path 3 is coated with an acoustic lass material 5 is provided. An acoustic energy dissipation in the material heats a substrate 7. When such a delay ray as this is connected to a feed back circuit of a high frequency amplifier 9 having a sufficient output, not only a stable vibration is provided, but also a surface temperature rises rapidly while surpassing an ambient temperature from the beginning of vibration. Then, according to the magnitude of a heat conduction of the substrate 7, its heat mass and all parasitic paths, a qwisent, temperature of the substrate eventually reaches a constant state at a value θ. The temperature is a function of the high frequency output of a vibration circuit.  When a fluid passes along the delay ray, the substrate temperature decreases because of forced convection heat-transfer. The decrease in temperature θ changes a frequency of an oscillator 1.
