Abstract: A photovoltaic power generator which outputs power generated by a solar battery panel through a DC-DC converter detects a time point at which a time differentiation value of output voltage of the solar battery panel substantially becomes zero, obtains power variation from the output power of the solar battery panel at each time point, controls the DC-DC converter based on the power variation, thereby swiftly and precisely tracking the maximum power point of the solar battery panel even when hysteresis loop (dynamic characteristic) is generated.

Abstract: In this vehicle roof molding, a molding body has shelf sections formed relative to the widthwise direction so as to oppose a bottom surface of an upper wall separated by an interval, and a slide plate is movably installed so as to be able to slide along the longitudinal direction of the molding body at a location opposing an opening of the shelf sections, and slide plate has elastic sections that protrude towards the shelf sections and force the slide plate towards the upper wall by receiving a reactive force from the shelf sections. Opening can be opened and closed by sliding slide plate.

Abstract: A window molding which is easy to install, and in the installed state remains stable and the external appearance is superior, and does not show floating or generate abnormal noise during highspeed cruising and is able to be flush-surfaced easily. The window molding is constituted by: a molding body attached along a space between a window plate and a body panel; a protruding rib protruding from the molding body towards an external surface of the window plate; a leg section extending from the molding body towards the space; a sealing lip extending from the molding body towards an external surface of a body panel; a linking lip extending from the leg section towards the space-forming surface of the body panel and linking with a tip of the sealing lip or in a vicinity of the sealing lip to form a hollow section.

Abstract: The object of the present invention is to provide a safety device for car seat which lies down instantaneously and converts a infant, a child, or an old person into a safe stance, reacting with an impact given in a front/rear collision, so as to protect the infant, child or old person safely against the impact in the front/rear collision. To achieve this object, the present invention comprises a seat for infant/child installed on a conventional car seat and lying down with reacting to the impact and sliding forward, a locking member maintaining a normal stance of the seat for infant/child, and a impact reaction member releasing a locking between the seat for infant/child and the locking member as the impact occurs. Therefore, by having the seat for infant/child lain down against the transmitted impact in the front/rear collision, the danger from the impact could be avoided, and thus the infant, child or old person could be protected more safely.

Abstract: A tone waveform reproduction apparatus, for an electronic musical instrument employing a plurality of samples in consonance with tone ranges, that can reduce a change in a timbre so that it will not be noticeable, and that can provide a natural transition of musical tones. An address generator generates a read address for a waveform memory. In the waveform memory are stored waveform data that differ for each timbre and each specific pitch range. A digital filter has a low-pass property and is controlled by a cutoff controller to adjust a timber or a tone quality. The cutoff controller generates a cutoff control signal for compensating for a discontinuity, at a point where tone ranges are switched, of reproduced frequencies of tone signals extracted from the waveform memory, and outputs the cutoff control signal fcn.

Abstract: In the conventional branch address calculator for an advance control processor, when a branch instruction reaches the execution step, a decision is first made as to whether the branch instruction is conditional or non-conditional, and then a target branch address (logical address) is calculated before the branch instruction is executed, so that the processing speed is slow. To increase the processing speed, a target branch address is previously calculated before a branch instruction reaches the execution step. Since the branch instruction can be executed immediately after the condition of the branch instruction has been decided, it is possible to eliminate the time required to calculate the target branch address after the instruction has reached the execution step.
