摘要： An ETC (electronic toll collection) system includes an antenna having a predetermined directivity for providing a limited radio-communication service zone. A vehicle sensor operates for detecting a vehicle which reaches a predetermined position in the limited radio-communication service zone. A radio signal is transmitted via the antenna. A decision is made as to whether or not a radio response to the radio signal is received via the antenna. In cases where a radio response to the radio signal is received, it is judged that there is an ETC vehicle incoming. In cases where the vehicle sensor detects a vehicle while a radio response to the radio signal is not received, it is judged that there is a non-ETC vehicle incoming.

摘要： The objective is to provide a data transfer control device and electronic equipment that are capable of reducing processing overheads, thus enabling high-speed data transfer within a compact hardware configuration. In addition to a FIFO, an internal RAM capable of storing packets in a randomly accessible manner is provided between a link core and a CPU in a data transfer control device conforming to the IEEE 1394 standard. The RAM storage area is divided into a header area, a data area, and a CPU work area, and the header and data areas are divided into areas for reception and transmission. Tags are used to write the header of a receive packet to the header area and the data thereof to the data area. The data area is divided into areas for isochronous transfer and asynchronous transfer. Pointers are provided for controlling the size of each area in RAM variably, and the size of each area can be varied dynamically after power is switched on. Each area has a ring buffer structure. The size of area storing the header or data of one packet is fixed.

摘要： A reflection preventing treatment is performed with respect to an edge face of a light shielding blade. The blade is composed of a film material made of a polyester, and is formed into a predetermined shape as a base piece. A flat face portion of the blade is capable of shielding an incident light, and an edge face portion is present in perpendicularly crossing to the flat face portion. An inner edge face of an aperture opening is included in this edge face portion. In order to form the blade, at first the base piece is punched from the film material in a predetermined shape. Subsequently, a chemical etching is applied to the edge face portion of the punched base piece so as to roughen the edge face portion. Accordingly, it is possible to suppress an unnecessary reflection of the incident light at the edge face portion. It is possible to evenly and efficiently roughen the inner edge face of the aperture opening by collecting a multiplicity of punched base pieces and dipping them in an etching solution.

摘要： A light-shielding blade material is provided that contributes to increased focal plane shutter speeds. A focal plane shutter has a front blade group and a rear blade group, each being composed of a plurality of light-shielding blades. At least one of these light-shielding blades is made of a Be—Al alloy material containing 40% by weight or more of Be, and has a thickness of 40 to 150 microns. This light-shielding blade is light in weight and high in stiffness, thereby significantly contributing the increased focal plane shutter speeds.

摘要翻译：相对于遮光叶片的边缘面进行防反射处理。叶片由聚酯制成的薄膜材料构成，形成为基材的规定形状。叶片的平面部分能够屏蔽入射光，并且边缘面部分存在于与平面部分垂直的相交处。孔口的内缘面包含在该边缘面部。为了形成叶片，首先将基片从薄膜材料冲压成预定的形状。随后，对冲压的基片的边缘部分施加化学蚀刻，以便使边缘部分变粗糙。因此，能够抑制入射光在边缘面部的不必要的反射。通过收集多个冲压的基片并将其浸入蚀刻溶液中，可以均匀有效地使孔开口的内边缘面粗糙化。

摘要： A focal plane shutter apparatus is constructed by a light shielding blade, a fitting pin attached to the blade and an arm which is slidably engaged with the fitting pin to open or close the blade. A surface hardness of the fitting pin is higher than that of the arm. Concretely, the surface hardness of the arm is Hv300 to 600, and the surface hardness of the fitting pin is Hv450 to 1000. The arm and the fitting pin are subjected to chemical polishing treatment. Furthermore, the fitting pin is plated with nickel, chromium, palladium or rhodium. The fitting pin and arm have a substantially equal material hardness, or the material hardness of the fitting pin is higher. As the case may be, the fitting pin or arm may be plated with gold. Such an arrangement can suppress generation and accumulation of abrasion powder in the focal plane shutter apparatus assembled into a digital camera.

摘要： A brightness limitation system is employed in a television circuit to prevent the black reference voltage level and the video signal from entering a minimum signal clipping zone, to provide precise correction signal, limiting the brightness, to maintain a constant black reference voltage level, and maintain a video signal with dynamic amplitude. The brightness limitation circuit detects a minimum signal level amongst the black reference signals from each color channel and compares the minimum signal with a fixed voltage level to generate a brightness feedback signal. The brightness feedback signal is then used to modify the black reference signal level for each color channel.

摘要： An image signal processing device is an image signal processing device that conducts a signal processing of an image signal from an image sensor. The image signal processing device includes a color interpolation circuit that conducts color interpolation of the image signal in unit of pixels from the image sensor, and a data conversion circuit that conducts a prescribed data conversion of the image signal that is color-interpolated by the color interpolation circuit. The data conversion circuit conducts a linear interpolation of digital data, which has a smaller bit count than the digital data of an image signal that is input, based on low-bit data of the digital data.
