Patent JP-H06130149-A (JP)
Title: Ultrasonic detector
Inventor: TAKADA MASAHIRO
IPC: G01S7/52
Filed: 1992-10-15
Abstract: PURPOSE:To prevent the deterioration of searching performance through a simple structure by utilizing the vibration of an integrated transmitter/receiver transmitting ultrasonic pulse and receiving reflected wave for removing contaminants e.g. mud, sand, rain drop, adhered to the transmitter/receiver. CONSTITUTION:When a transmitter/receiver 1 is fixed to a mobile and operated outdoors, the transmitter/receiver 1 is susceptible to adhesion of foreign matters, e.g. mud, sand, rain drop, and thereby transmission output lowers or the profile of ultrasonic beam is deformed. At the time of reception, receiving sensitivity lowers or directivity is altered. If the contaminants are not removed by the wave 102 outputted from the transmitter/receiver l during normal measurement, a contaminant removing unit 5 applies an AC driving signal 105 for removing contaminant to the transmitter/receiver thus spattering contaminants adhered thereto through ultrasonic vibration. When the amplitude of the driving signal 105 is set higher than that of a driving signal 101 being fed from a transmission wave driving circuit section 2 during normal measurement, contaminant removing effect is enhanced.

Title: Cap of writing instrument
Inventor: SUZUKI KEIICHI
IPC: B43K25/02
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent a clip from injuring the wall of the windpipe by a method wherein the clip is provided on the outer surface of a cap so that the clip serves as a protrusion for ensuring an air flow channel to prevent suffocation in the case that the cap is erroneously swallowed, and further the clip is covered with soft material so that the clip softly touches the wall of the windpipe. SOLUTION: A clip 2 of metal is attached to a head of a cap body 1 being a cylinder with bottom and the base portion 4 of the clip 2 is fixed to a mount hole 3 formed at the head of the cap body 1 and a rounded part 6 at the end of a holding portion 5 of the clip 2 is located near an opening of the body 1 so as to serve as a protrusion for ensuring an air flow channel to prevent suffocation in the case that the cap body 1 is erroneously swallowed. And the holding portion 5 of the clip 2 is covered with an elastic tube 7 made of silicone rubber. As a result, even if a child or the like has erroneously swallowed the cap body 1, the body 1 softly touches the wall of the windpipe so that the wall is prevented from being injured.

Abstract: PURPOSE: To make possible to manufacture a subject device by a method for using one etching level by making each transmitting cell perform phase inversion at its left boundary and right boundary and transmit surface wave and making each reflecting cell has a reflection coefficient for performing phase inversion at its left boundary and right boundary. CONSTITUTION: An electrode is grouped into transmitting cells E1 to E3 and reflecting cells R1 to R4 , and alternately aligned on the axis of the propagation of sound wave. Only the transmitting cells E1 to E3 are electrically connected to a node S and exciting sound wave on the surface of a substrate, but the reflecting cells R1 to R4 change the propagation characteristic of sound along this axis. That is, each transmitting cell performs phase inversion on the wave in its left and right boundary areas and transmitting thus obtained wave, and each reflecting cell has a reflection coefficient in phase inversion in the left and right boundary areas. Thus, the limitation of the frequency of surface wave is to be unnecessary, and further the manufacturing method is simplified.

Abstract: PURPOSE:To optimize the supply of a developer by detecting a voltage applied to a developing cylinder and detecting the amount of the developer, and interrupting image forming operation and supplying a developer when a specific level is outputted continuously for a certain time. CONSTITUTION:The AC voltage applied to the developing cylinder 501 is detected by an AC voltage detection plate 503 through toner and inputted to an input terminal 509.
