Abstract: In one embodiment of the present invention, the automotive display apparatus has two concave mirrors arranged below the windshield in such a way that light from the display of an indicator which shows driving condition information such as car speed is reflected by one of the concave mirrors toward the other concave mirror, which then reflects the light toward the windshield that further directs it toward the driver's seat. A drive can thus see a remotely formed virtual display image within a viewing field of the windshield. The first concave mirror, which directly receives light from the indicator and reflects it toward the second concave mirror, is mounted on a plane mirror in such a manner that it can be moved into or out of a light path that extends from the indicator to the second concave mirror. When the first concave mirror is in the light path, the display image is magnified and hence the virtual display image is formed at a remote position from the driver.

Abstract: A filtering vessel adapted to accommodate a filter bag for filtering a liquid under pressure. The vessel comprises a top open cylindrical housing having a sidewall and a bottom with an outlet port, and a basket supported within the housing to retain the filter bag therein. A jacket is formed to surround a top portion of the housing to form therebetween an annular fluid passage which is open at its upper end and communicates with an inlet port formed at the jacket for coupling a pressurized liquid supply line. Also included in the vessel is a top cover detachably mounted on the housing and the jacket to close the top opening of the housing as well as that of the annular fluid passage. The top cover is formed in its lower surface with peripheral openings and a center opening which are intercommunicated within the top cover.

Abstract: A liquid charging method including the following steps. First, supplying liquid into and then discharging the liquid from an enclosed space provided above a pit block, to fill the liquid into a plurality of pits on the upper surface of the pit block. Each of the pits open at the upper surface of the pit block and have a small-diameter nozzle formed at the bottom of the pit block. Second, a tray having an array of containers with open upper ends is fed to be positioned below the pit block at a specified liquid-charged position. Pressurized air is supplied into the enclosed space to apply pressure on the liquid in the pits, thereby forcing the liquid in the pits to flow through the small-diameter nozzles into the array of containers on the tray.

Abstract: The connector consists of a connector housing with a plurality of terminal accommodating chambers and a terminal locking member mounted to the rear portion of the connector housing. The terminal locking member is fitted to the connector housing in one of two engagement states--a preliminarily engaged state and a fully engaged state. The terminal locking member has resilient support pieces for fixing the terminal lugs in the terminal accommodating chambers. When the terminal locking member is moved backwardly from the preliminarily engaged state, the resilient support pieces ride on triangular engagement projections formed on the connector housing, moving outwardly out of the insertion path of the terminal lugs. This allows the terminal lug in question to be pulled out without disengaging the terminal locking member from the connector housing.

Abstract: Provided is a rotor structure of a radial type synchronous motor having a rotor core (10) is held between permanent magnets (12) wherein end plates (14) are attached to ends of the rotor (8) in a direction of the central axis (6) of the rotor, each of which plates is provided with projecting portions (16) to regulate a radial position of an outer face of the rotor core. This prevents a projection of the rotor core and permanent magnets in the radial direction due to a centrifugal force caused by a rotation of the rotor. Therefore, a rotor structure able to withstand a strong centrifugal force can be provided.

Abstract: Supplied selectively to a recording system circuit of a VTR are a first component signal comprising three primary color signals R, G and B and a second component signal comprising a luminance signal Y and two types of color difference signals P.sub.B and P.sub.R. The first and the second component signals pass through a group of LPFs (1, 2, 3) having the same pass characteristics and then are A/D converted at the same sampling clock. The component signal converted into a digital signal is applied to a matrix circuit 11. Respective coefficients of the matrix circuit are switched according to a type of the inputted component signal, and as a result, a second digital component signal is always outputted at a fixed delay time from the matrix circuit. Two color signal data which are over-sampled included in the second digital component signal are applied to decimation digital filters 14 and 15 to reduce data densities thereof.
