Abstract: Provided is an altitude calculation method for a flying body including calculating an altitude of the flying body by using information on horizontal coordinates of the flying body, a reception signal strength of a radio signal, and altitude calculation auxiliary information obtained in advance.

Abstract: A fault diagnosis method is provided for an evaporated fuel processing device including a canister including a charge port connected to an upper space of a fuel tank, a purge passage connecting a purge port of the canister and an intake system, and including a purge control valve, a drain passage including a drain cut valve, and a pressure sensor. The pressure sensor is configured to sense, as a purge passage pressure, a pressure between the purge control valve and the canister in the purge passage. The fault diagnosis method includes performing a purge by opening the purge control valve in a state in which the drain cut valve is controlled to be opened; measuring an actual pressure variation by the pressure sensor; and diagnosing a closing fixation of the drain cut valve by comparing a predetermined pressure variation and the actual pressure variation.

Abstract: An access count device and the like in a semiconductor memory are disclosed, which count accesses to row addresses in the semiconductor memory with a smaller circuit scale. An access count device includes a row-address storage unit configured to store up to a specific number n (n is an integer equal to or more than 1) of row addresses specified in accesses to memory cells, a counter configured to count an access frequency to each row address stored in the row-address storage unit, and a reset controller configured to notify the row-address storage unit to replace one of the n row addresses with a new row address or discard one of the n row addresses, and also configured to notify the counter to reset an access frequency to the row address replaced or discarded.

Abstract: A blood analyzing system for analyzing the level of content of a component (such as glucose) of blood collected from a person or animal. In the blood analyzing system, a pipet unit includes a drop meter for measuring the volume of the blood sample actually dropped onto a test slide. Reacting to a reagent coated on the test slide, the blood sample changes its color, which is optically detected. A content calculating circuit calculates the level of content of the blood sample based on the received light signal. The content calculating circuit also corrects the calculated results according to the volume of the actually dropped blood sample.

Abstract: A dot matrix type printer head in which delays in the release of print hammers are eliminated by providing release coils only in alternate hammer positions, or alternatively, activating at one time only release coils in one of even-numbered and odd-numbered hammer positions. A rear yoke and a permanent magnet affixed to a lower leg of the rear yoke are provided in common for all hammer positions. An upper leg of the rear yoke is divided into a plurality of pole pieces. Hammer elements are provided having lower ends rigidly affixed to the rear yoke at positions adjacent the permanent magnet and upper ends retractable against pole faces of corresponding pole pieces by the magnetic force of the permanent magnet. In a first preferred embodiment of the invention, release coils are provided around only even-numbered or odd-numbered pole pieces.

Abstract: A printing apparatus including a plurality of drive coils for driving printing hammers arranged longitudinally in side-by-side relation at one side of a core of the U-shape. A first cooling fluid passageway is defined inside the core of the U-shape to allow a cooling fluid for cooling the drive coils to flow therethrough, and a second cooling fluid passageway is defined outside the core by a duct to allow the cooling fluid for cooling the drive coils to flow therethrough without escaping to the outside by diffusion. A current of cooling fluid is forcibly fed into these cooling fluid passageways by a fluid machine.
