Abstract: Binary information previously recorded in an innermost rim side area is enabled to be stably reproduced. A record medium is formed by sequentially laminating a first information layer 2, an intermediate layer 3, a second information layer 4, and a cover layer 5 onto a substrate 1. First grooves are previously formed in the innermost rim area of the substrate 1. Second grooves are previously formed in an area where data is recorded. The first grooves are set to be shallower and narrower than the second grooves. Thus, such a situation that a BCA signal is modulated by diffraction due to the grooves can be reduced.

Abstract: A motorcycle-detecting device according to the present invention is mounted on an automotive vehicle. The device includes ultrasonic sensors for detecting objects around the vehicle, a device for predicting that a motorcycle is approaching the vehicle, and a device for adjusting a detection distance and a detection sensitivity of the ultrasonic sensors. When the predicting means predicts a motorcycle approach, the adjusting device makes the detection distance longer than a normal distance and the detection sensitivity higher than a normal sensitivity. Illuminating devices may be mounted on the vehicle to make the motorcycle passing by visible. A warning may be given to a driver when a motorcycle passing by is actually detected by the sensors. Information regarding the detected motorcycle may be given to other vehicles. According to the present invention, the motorcycle passing by the vehicle is surely and stably detected to thereby avoid any traffic accident with the motorcycle.

Abstract: A warning apparatus acquires traffic light information from outside of a vehicle through a traffic information acquisition unit, and travel information regarding a travel condition of the vehicle through a travel information acquisition unit. Then, the warning apparatus determines whether an intersection is safely passable based on the traffic light information and the travel information. When the intersection is not safely passable, the warning apparatus searches similar traffic light information and similar travel information relative to current traffic light information and current travel information by checking records of past driving operation in a storage unit. Then, the warning apparatus predicts a driving operation of a driver when the driver is warned for determining the warning contents based on the operation information in association with the similar traffic light information and the similar travel information.

Abstract: Audio-centered information is stored on a unitary medium by using a Table-of-Contents (TOC) mechanism that specifies an actual configuration of various audio items on the medium. In particular, each one of a set of one or more Track Areas gets at least two mutually logically conforming Sub-TOCs assigned. This allows to retrieve any constituent Sub-TOC part from at least any correct copy of the Sub-TOCs. Furthermore, one or more Master-TOCs are provided for specifically pointing to each of the Sub-TOCs.

Abstract: A signal level detector to detect the level of 1-bit digital signal is provided. It includes a level detector (12) supplied with a sequence of 1-bit digital signals decoded by an audio decoder (5) and which counts the number of 0 (zeros) or 1 (ones) included in the row of a predetermined number n of 1-bit digital signals to detect the level of the 1-bit digital signal, and an indication unit (13) to indicate the signal level detected by the level detector (12).

Abstract: The object of the invention is to provide a handy type visually determinable ATP measuring reagent which can be easily handled and has good measuring sensitivity. The invention is an ATP measuring reagent which rendered possible visual determination by amplifying the reaction to form glucose 6-phosphate from glucose through the joint use of ATP contained in a sample and acetyl phosphate contained in the reagent with glucokinase and acetate kinase contained in the reagent, and further leading it to a visualizable color reaction by the combination of glucose-6-phosphate dehydrogenase and diaphorase.

Abstract: An ejector pin of an injection mold includes a sleeve, a valve structure, and a biasing member. The sleeve has a passage hole and an enlarged hollow portion, which communicate with each other via a stepped portion engaged therebetween. The valve structure has a valve portion and a collar portion, which are disposed in the sleeve. The collar portion of the valve structure is biased by the biasing member such as a spring and stopped by the stepped portion. Gaps interposed between the valve structure and the sleeve serve as a gas passageway through which gas in a molding cavity is exhausted by a vacuum pump.

Abstract: A cellular phone has back light illumination for its display unit and a key unit, and is capable of receiving internet information, receiving karaoke songs, or receiving and sending electronic mails. In the case that the cellular phone is used for electronic mailing, it is checked whether the cellular phone is operated in a character/number input mode. If it is not in the input mode, only the display unit and a function key part of the key unit are illuminated. A ten key part of the key unit is illuminated only when it is to be manipulated to change display on the display unit. In the case of executing the internet function or the karaoke function, the illumination control for the display unit and the key unit is controlled in the similar manner.
