IPC: H04R1/44
Filed: 1984-12-06
Abstract: PURPOSE:To obtain a low-frequency high power transmitter with small size, light weight and excellent sound radiation efficiency by providing a piston sound radiator to an active columnar body using a piezoelectric ceramic device and a lever via a connecting rod. CONSTITUTION:The active columnar body 31 is formed by using a pizoelectric ceramic and longitudinal vibration is excited by applying a voltage thereto.

Abstract: PURPOSE:To measure the pressure sensitivity by using an electrode that is formed at the surface by placing a wafer on a wafer stage, thereby sucking a diaphragm under vacuum from the rear of a semiconductor pressure sensor by utilizing holes mounted at a wafer stage. CONSTITUTION:An electrical measurement is carried out from the surface of a semiconductor pressure sensor 1 and a pressure is applied from the rear of the semiconductor pressure sensor 1, so that the pressure sensitivity of the sensor 1 is measured in a wafer process. Thus, when the wafer 5 is placed on a wafer stage 2 and recessed parts 15 that are prepared at the rear side of the semiconductor sensor 1 are sucked under vacuum by utilizing through holes 3, a negative pressure equivalent to a stage of pressure that is applied from the surface to the recessed parts 15 of the semiconductor pressure sensor 1 is developed. Then a diaphragm 16 is deformed in the same manner that is deformed in the case where the pressure is applied from the surface side, so that is state of diaphragm makes it possible to measure the pressure sensitivity.

Title: Deciding method of signal accompanied with chattering and load protective device
Inventor: MATSUZAKI HIDEAKI
IPC: G06F11/10
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To decide the state of a reading signal in short time, while eliminating the influence of chattering. SOLUTION: Signals are read at a prescribed time interval (step 100). The prescribed weighing value fixed according to the reading time is assigned to each signal (step 102). The product of the logical value of each signal and the weighing value is determined and a so-called convolution processing is performed by determining the sum of the products of these values (step 104). When the value of the convolution processing exceeds a prescribed value, a decision as the state of the logical value '1' of the signal is performed (step 106). When the signal changes from the logical value '0' to the logical value '1', the decision of the state of the signal can be performed more quickly as compared with a conventional decision, evading the erroneous decision due to chattering even in the case of the change accompanied with chattering.
