IPC: H04M11/00
Filed: 1990-09-07
Abstract: PURPOSE:To make the polarity control of a line unnecessary by storing the output of a feeding polarity detecting means in a specified state of the line, and detecting the feeding polarity of the line at the optional state of the line by referring to information stored in an storage means. CONSTITUTION:In the case that the lines L1, L2 are connected as shown by a full line, a first polarity detection circuit DETA operates as the detection circuit of normal polarity, and in the case that the lines L1, L2 are connected as shown by a broken line, the detection circuit DETA operates as the detection circuit of reverse polarity. Since the feeding polarity to be impressed to the lines L1, L2 is either the normal polarity or the reverse polarity, while the detection circuit DETA operates as the detection circuit of the normal polarity, if no signal appears in its output OA, it comes to be detecting the reverse polarity. On the contrary, while the detection circuit DETA operates as the detection circuit of the reverse polarity, if no signal appears in its output OA, it comes to be detecting the normal polarity.

IPC: G02B6/122
Filed: 1986-10-09
Abstract: PURPOSE:To permit coupling of an optical integration module for bidirectional transmission and optical fiber with high efficiency by disposing an input waveguide of a refractive index n1 and optical waveguide of a refractive index n0 (n1>=n0) in parallel and contact with each other so that both the waveguide have a tapered shape. CONSTITUTION:The input waveguide 12 of the refractive index n1 and the optical waveguide 14 of the refractive index n0 are disposed in parallel and contact with each other via the layer of a refractive index nc1 on a substrate 8 (n1>=n0>nc1). The outer peripheries of the two parallel disposed waveguides 12, 14 are coated with a layer of a refractive index nc2 (n1<=n0>nc1<=nc2). An optical fiber 5 or semiconductor optical element is disposed to one end of the input waveguide 12 and the opposite side thereof is formed to the tapered shape. The waveguide 14 on one end side of the waveguide 12 is also formed to the tapered shape. A light signal repeats reflections in the tapered parts, by which the reflection angle thereof is increased and the light is efficiently coupled to the waveguide 14 or the waveguide 12. The coupling of the optical integration module for bidirectional transmission and the optical fiber 5 is thereby permitted with high efficiency.

Abstract: PURPOSE:To obtain the running toy by which a player can enjoy such a sense as an automobile is driven by himself by constituting it so that a sel sound and an engine sound are generated at the time of start, and at the time of running 1 etc., respectively. CONSTITUTION:When a start sound/engine sound switching mechanism 500 operates and a large diameter gear 301 is engaged to a gear 204, a start sound generating mechanism 300 generates a start sound being similar to a sel sound by rubbing of a gear 302 which follows a rotation of a small diameter gear 302 and a soundins tongue 303.

Title: Control device for robot
Inventor: KONDO MOTOHISA
IPC: B25J13/00
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To carry out the synchronous control of a robot so that work may be carried out at a fixed position, and the motion course of a robot arm may be fixed in case where work is carried out using the robot fixedly installed to a conveyed workpiece. SOLUTION: The moving speed of a robot arm 14 is corrected on the carrying speed (reference carrying speed) of a conveyer 10 at the time of setting up a motion program and actual carrying speed (actual carrying speed). In case where the actual carrying speed is slow, the moving speed of the robot arm 14 from an early position to a work starting position is also reduced to prevent the work starting position and its course to this point from varying. In addition, pause time is computed on the reference carrying speed, the actual carrying speed and time required for working process, and after the ending of work, the robot arm 14 and a work piece are planned to move together for the pause time.

Title: Device and method for ultrasonic inspection
Inventor: KOIKE MASAHIRO
IPC: G01N29/26
Filed: 1992-09-08
Abstract: PURPOSE:To accurately find the position of an ultrasonic wave reflecting source by using an electronic scanning type ultrasonic inspection device. CONSTITUTION:At the time of transmitting ultrasonic waves to an object 2 to be inspected from an array probe 1, a transmission delay time circuit 4 gives transmitting timing required for converging ultrasonic waves or propagating the ultrasonic waves in an aimed direction to each element. Reflected waves from a reflecting source in the object 2 is received by the probe 1 and sent to a reception delay circuit 5. The circuit 5 adds each received signal to another after giving the signals delay time which is required for making the signals to become the same in phase and a propagating time measuring instrument 7 measures the propagating time of the ultrasonic waves. On the other hand, a delay time error storage device 8 stores measured delay time errors in advance and an eccentricity calculator 9 calculates the peak position of the ultrasonic beam based on the delay time errors and sends the peak position to a reflecting source position corrector 10. The corrector 10 finds the propagating direction of the ultrasonic beam from the peak position and propagating distance of the beam from the propagating time and decides the position corresponding to the found direction and distance as that of the reflecting source.

Abstract: PURPOSE:To make the entire discharge tube to emit light while reducing the size of a luminaire by installing several microwave radiators along the axis of a bar-like discharge tube and connecting a microwave generator where a semiconductor element is used to these microwave radiators. CONSTITUTION:Microwaves delivered from a microwave generator 4 are applied to several microwave radiators 3, which are installed along the axis of a bar- like discharge tube 2, to generate an electric field of microwaves at ends of the electrodes 81-8n of each radiator 3.

Due to the several microwave radiators 3 installed along the axis of the discharge tube 2, the entire discharge tube 2 discharges and emits light. Since the microwave generator 4 consists of a microwave-generating circuit 10 where a transistor is used, the size of the luminaire can be reduced.

Title: Ink-jet recording device
Inventor: MORITA OSAMU
IPC: B41J2/175
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To detect the ink residual amount in an ink tank by a simple and inexpensive method by providing either of light emitting elements or light receiv ing elements of a plurality of element pairs as common members. SOLUTION: A light beam irradiating from a light emitting element 15 enters a prism 180 formed by molding integrally with the bottom surface 183 of an ink tank. In the case where an ink 103 remains sufficiently, the incident light beam is refracted by the prism surface so as to be absorbed by the ink 103 via the optical path (1)→(2) route, and thus a light receiving element 17 cannot detect the reflected light beam. To the contrary, in the case that the ink residual amount is substantially zero i.e. a liquid level 101, the incident light is totally reflected by the prism surface so that the light receiving element 17 detects the reflected light beam returned by the optical path (1)→(3)→(4) route.  Moreover, in the case of (B), a light beam emitted from the light emitting element 15 is totally reflected by the oblique surface of the prism so as to be directed to a light receiving element 16. Therefore, existence or absence of an ink in an ink tank can be detected continuously at a plurality of positions displaced in the paper feeding direction by an optical unit comprising a light emitting element and two light receiving elements.
