Abstract: A rotational angle detector for detecting the rotational angle of the rotor in a wide range without requiring dark current. A first detection gear including an m number of teeth and a second detection gear including an L number of teeth are each engaged with a main gear rotated integrally with a steering shaft which includes an n number of teeth. A microcomputer calculates a rotational angle ? of the steering shaft using a rotational angle ? of the first detection gear within one cycle and a rotational angle ? of the second detection gear within one cycle.

Abstract: In a semiconductor photo-detecting element (an avalanche photodiode), a high-sensitivity element is obtained by incorporating a multiplication layer having high-performance multiplication characteristics. By using a structure which reduces an electric field applied to an etching stopper layer, it is possible to use a multiplication layer having higher-performance multiplication characteristics (a multiplication layer which performs multiplication with a high electric field). The first method to realize this is to use a conductivity type multiplication layer. The second method is to use a structure in which a field buffer layer of the second conductivity type is incorporated. As a result of the use of these methods, a structure which applies an electric field lower than the multiplier electrical field to the etching stopper layer is obtained.

Abstract: The processor of a receiving device does not execute acquisition and release of resources of a band and a channel for the isochronous data transfer every time the processor receives data from the sending device by isochronous transfer, but executes the acquisition of the resources of the band and the channel for the isochronous data transfer via the bus and an I/F board only when the completion of a bus reset is detected and holds the resources until the next bus reset is caused. By this processing, the receiving device can consistently secure the resources necessary for the isochronous data transfer to the sending device so long as the resources acquisition is successfully achieved when the bus reset is completed.

Abstract: In the case where a rewind or fast-forward button is clicked after a playback button is clicked, a CPU on controller side sets a reproduction flag bit to “on” upon receipt of a response frame from a DV camcorder indicating that the playback command is normally accepted, without checking whether the DV camcorder is during playback operation or not, and determines what kind of control command should be sent to the DV camcorder based on the reproduction flag bit and the clicked button. The controller can determine the control command without waiting for the response to an inquiry about whether the DV camcorder is during playback operation or not, thus quickly sending a rewind playback or fast-forward playback command to the DV camcorder.

Abstract: The present invention provides a terminal capable of receiving information corresponding to scenes of a television broadcast while the television broadcast is being viewed on a television set. A contents delivery system includes the terminal and an output device for receiving and displaying broadcast data delivered from a broadcasting station. The terminal has an identification information acquisition section for acquiring identification information displayed on the screen of the output device, the identification information being included in the broadcast data and changing with time. A relevant information extractor extracts relevant information, relating to contents to be broadcast according to the broadcast data, from the identification information. An output section outputs the relevant information extracted by the relevant information extraction section.

Abstract: A method of providing a program for a printed board packaging line is disclosed. A board packaging line coordinating computer downloads the service contract information and the application program contained in the contract information from an application server, and defines the board packaging line covered by the program and the device configuration of the line. The device configuration thus defined is uploaded to the application server, which, based on the device configuration thus uploaded, searches a prepared device driver group for a required device driver. This device driver is downloaded and set in each device by the board packaging line coordinating computer.

Abstract: An infrared ray detector comprises an infrared ray detecting member (25), a pair of opposing members (32, 33) each having a plurality of infrared ray transmitting portions (34, 35) and infrared ray non-transmitting portions (36, 37), a pair of vibrators (38, 39) and a driving signal supplying circuit (59, 60). The pair of opposing members (32, 33) are disposed in the area of incidence of infrared rays to the infrared ray detecting member (25), and are displaced periodically by the pair of vibrators (38, 39). The pair of vibrators (38, 39) are driven by a driving signal from the driving signal supplying circuit (59, 60), the amplitude of the driving signal being selected to be smaller than that of a driving signal used in a case where there are periodically repeated a state in which both of the infrared ray transmitting portions (34, 35) of the pair of opposing members (32, 33) are completely opened and a state in which those are completely blocked, subject to no change in an ambient temperature.

Abstract: An infrared ray detecting apparatus comprises an infrared ray detecting element (5), bimorph elements (8a and 8b), a transistors (53, 54), a DC-DC converter (55), and a volume (56). A square wave signal is applied to a base of the transistor (53) from a microprocessor (40) included in a microwave oven and a signal having a constant level is applied to a base of the transistor (54). The DC-DC converter (55) is continuously driven in response to an emitter output from the transistor (54) so that a constant voltage -E.sub.0 V which is extremely stable is supplied. A voltage -E.sub.s V which is obtained by regulating properly the constant voltage -E.sub.0 V by means of the volume (56), is applied to central electrodes of the bimorphs (8a and 8b), while a square wave signal varying between 0 V and -E.sub.0 V in response to an on/off state of the transistor (53), is applied to a surface electrodes of the bimorphs (8a and 8b).

Abstract: An infrared radiation detector is provided for receiving an infrared radiation emitted from a material being cooked placed in a cooking chamber in a microwave oven. The microwave oven is provided with a keyboard, a digital display and a microcomputer, such that when a temperature operation mode is set by entry from the keyboard the set temperature data is stored in a memory. In the temperature operation mode, the temperature of the material being cooked is detected in terms of a voltage associated with the output from the infrared radiation detector and a magnetron of the microwave oven is energized until the above described detected voltage becomes equal to the set temperature data and the magnetron is deenergized when both coincide with each other. In the temperature operation mode the temperature of the material being cooked is displayed by the digital display.
