Title: Audio equipment to connect speaker
Inventor: UEDA EIJI
IPC: H04R3/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To suppress noise in the case of connection to or disconnection from a speaker by interrupting supply of an audio signal from an audio signal supply device to a terminal when a detection signal denoting at least either of connection and disconnection operations from a speaker connection state detection means is obtained. SOLUTION: In the case that a power switch 11 of an amplifier 1 is closed and a speaker 2 is connected/disconnected while receiving an audio signal to an input terminal 3, when a connected conductor 19 is open, a state detection switch 17 is closed to energize a relay 16 and to turn off a switch 7. Thus, supply of an audio signal to a terminal 8. Even when an improper contact takes place between the connection conductor 19 and a terminal conductor, no audio signal is supplied to the speaker 2 and no noise is generated. Furthermore, since the switch 7 is tentatively turned off when the connection conductors 19, 20 connect to terminals 8, 9, no noise is produced from the speaker 2.

Title: Video camera
Inventor: ANDO TOMOHIRO
IPC: G02B7/02
Filed: 1992-05-27
Abstract: PURPOSE:To obtain a video camera in which an object is irradiated with the sufficient quantity of light even in the case of photographing in a close distance and photographed as a bright image by providing an illuminating light source behind a 1st lens constituting a front lens on the inner surface of an outside barrel. CONSTITUTION:The illuminating light source 11 is provided just behind the front lens 1a constituted as a 1st group lens on the inner surface of the outside barrel 3. In the case of photographing in the close distance illuminating light projected from the light source 11 passes the front lens 1a, and the object is irradiated with the sufficient quantity of light. In the case of photographing without illuminating, the light from the object is focussed into an image on an image pickup element 2 by a lens system 1 in the outside barrel 3. This formed optical image is converted into electrical information by the image pickup element 2. In the case of photographing in the close distance with low illuminance, the object is irradiated with the illuminating light projected from the light source 11. Therefore, the bright image is obtained even in the case of photographing in the close distance.

Title: Goniometer type optical measuring device
Inventor: TAKAHATA SHIGEHIRO
IPC: G01N21/55
Filed: 1994-05-24
Abstract: PURPOSE:To simplify sample inclination setting operation with a simple device structure by relatively moving a light receiving surface forward and backward to an image of a radiating light convergent point of a telemeter optical system on emitted light from a sample. CONSTITUTION:When an attachment lens 11 is removed from between a telemeter lens 2 and a light receiving element 3, an image of a light radiating point of a sample is formed on the light receiving element (a slit 10). Even if an inclination of the sample is changed in this condition, a light condensing point on the light receiving element does not move. Here, when a lens 1 is inserted between the lens 2 and the element 3, since the light condensing point on the element 3 separates from a light receiving surface and approaches the lens 11, even if the new light condensing point does not move when an inclination of a sample surface is changed, since the direction of light condensed on the light condensing point is different from the beginning, a light radiating spot on a light receiving element surface (a slit surface) comes to move, so that an inclination change in the sample can be detected. When detection of the sample inclination becomes possible, an angle of the sample can be set.

Filed: 1990-05-28
Abstract: PURPOSE:To enable obtaining of stable beam without edge convergence by providing measures by which a charged particle beam can pass through vertically to each incident and discharging plane. CONSTITUTION:On the Wiggler device in this invention, predetermined electric current is passed to each of 3 poles deflected electromagnets 5, 6 and 7, in advance, in order to generate magnetic flux B alternatively to a Z axis direction, and therewith N and S poles are constituted alternatively. In this way, incident beam from an incident plane of the electromagnet 5 is deflected by slant angle theta1 (0 < theta1 < 90 deg.) to an X axis, and is discharged perpendicularly to a discharging plane. And then, incident beam perpendicular to an incident plane of the electromagnet 7, is deflected and discharged perpendicularly to the discharging plane, namely, to the X axis direction. Accordingly, since beam 1 passes through perpendicularly to each incident and discharging plane of electromagnets 5, 6 and 7, any lens function does not work and momentum is not changed.

Abstract: PURPOSE:To enable dimensional measurement of pattern with low differential contrast between the wiring section and the space section and detection of inter-line leak or shortcircuit through contactless means by additionally providing second beam irradiating means having lower acceleration voltage than charged beam. CONSTITUTION:At first, second electron beam 2 is deflected and irradiated onto the wiring to be measured.
