Abstract: An AC/DC power supply is connectable to either AC or DC and includes a power transformer (PTR) circuit, a rectifier circuit, and a switching circuit having first (Q1) and second switching devices (Q2) effective when the voltage input is AC and DC, respectively, to output pulses to the power transformer circuit (PTR). A control circuit (PWMC), when sensing an AC voltage input, enables the rectifier to rectify the voltage input before applied to the power transformer circuit (PTR), and also enables the first switching device (Q1) to output pulses to the power transformer circuit (PTR). The control circuit (ISC), when sensing a DC voltage input, disables the rectifier and enables the second switching (Q2) device to output pulses to the power transformer circuit (PTR). A duty-cycle control circuit (PWMC) controls both the first (Q1) and second switching devices (Q2) to control the duty cycle of the pulses supplied thereby to the power transformer (PTR) circuit.

Abstract: This invention aims to temporarily lock and smoothly couple and detach a lever type connector. After a hood 13 is opposed to a fitting portion 12a, the hood 13 is inserted into the fitting portion 12a, so that a lock portion 29 is clamped between an upper engaging projection 23 and a lower engaging projection 22. Then, a female connector housing 12 is temporarily locked in a male connector housing 11. At this time, a cam follower boss 20 is inserted into a cam groove 17 in an actuating lever 16 and both the housings 11 and 12 are coupled by turning the lever 16. In order to detach the housings from a coupled position, the lever 16 is turned from the coupled position to a detached position. Even if the female connector housing 12 is extracted from a right side area in the case that an extraction resistance at a left side area is larger than that at the right side area, the housing 12 abuts on the lower engaging projection 22b at the right area, thereby correcting an inclined posture. Thus, since the female connector housing 12 is always properly arranged in the male connector housing 11, it is possible to smoothly couple and detach the housings.

Abstract: A digital phase lock loop controller (DPLL) (10) incorporates an adjustment generator (34) for continually adjusting the sensitivity of the DPLL (10) to reduce injected noise. The DPLL also comprises an error detector (16), a frequency adjuster (22), a first oscillation generator (28), and a divider (32) that function in a manner common to many DPLLs (10). However, the adjustment generator (34) continually adjusts the operation of the frequency adjuster (22) based upon the relative phase difference between a reference oscillation (12) and a feedback oscillation (14) in order to vary the sensitivity of the DPLL (10). When the reference oscillation (12) and the feedback oscillation (14) are relatively in phase, the sensitivity of the DPLL (10) is low. Oppositely, when the reference oscillation (12) and the feedback oscillation (14) move out of phase, the sensitivity of the DPLL (10) increases.

Abstract: An air-purifying filter (1, 3, 24) comprises a carrier base
(101-103, 301-303) and a TiO 2 -Pd composite catalyst supported
on the carrier base. CO in air to be treated by the filter
(1, 3, 24) is adsorbed onto the Pd surface and thus decomposed
by oxidization to CO 2 , whereas sulfur compounds in the air are
also adsorbed onto the Pd surface and then transferred to the
TiO 2  surface where they are decomposed by oxidization to SO 4   2- when
TiO 2  is subjected to irradiation. Preferably, Pd exists in
a relatively small quantity at a first side of the carrier base
(101-103, 301-303) in the vicinity to a light source (2) of
irradiation and in a larger quantity at a second side opposite
to the first side. The first side is preferably located in an
upstream area of air to be treated by the filter (1, 3, 24). An
air-purifier (10) utilizing this filter (1, 3, 24) is mounted
in an automobile (200), preferably on a rear shelf (204) or in
a trunk room (202). The air-purifier (10) has a light source
(2) for irradiating the filter (1, 3, 24), and an exhaust port
(28), arranged at a position where a negative pressure of the
automobile (200) is generated during driving, to exhaust any
substances adsorbed to the composite catalyst to the outside of
the automobile (200).

Abstract: The mixed powders of a lithium compound and a
transition metal based compound are formed into shaped
parts, which are packed to form a bed 6 on a porous plate 5
in the bottom of a reaction vessel 7 placed on a support 10
in a firing furnace 8 equipped with an electric heater; the
packed parts are fired with an oxidizing gas such as air
being forced through the bed 6 at a superficial velocity
higher than a specified value via a gas feed pipe 3
connecting an air pump 1, a flow regulator 2 and a
preheater 4 and the gas emerging from the bed 6 is
discharged into the air atmosphere through a ventilation
port 9. Even if increased amounts of the mixed powders have
to be fired, the invention process enables the production
of a lithium complex oxide as an active material that is
homogeneous and which features excellent cell
characteristics. If the manufacturing conditions are
controlled such that the media diameter as a powder
characteristic of the lithium complex oxide is within an
appropriate range while, at the same time, the ratio of the
median diameter to the specific surface area diameter is
adjusted to lie within an appropriate range, one can
produce an active material that has not only high initial
capacity but also improved cycle characteristics.

Abstract: A picture transmission system capable of establishing arbitrary picture connections with picture inputting units exceeding in number channel resources of a transmission medium for multiplexing and transmitting video information taken through the picture inputting units. A picture sending state storage unit provided corresponding to each of the picture inputting units virtually retains channel resources whose number equals the number of picture outputting units to which the picture inputting units are in connection. For picture connection switching from one picture outputting unit to a different picture inputting unit, the picture sending state storage unit gives its channel resource to the different picture inputting unit. The system is provided with a picture connection managing unit for controlling the picture connections between the picture inputting units and the picture outputting units. The picture connection managing unit accepts a picture connection request to perform the centralized management of channel resources of the transmission medium to allow dynamic channel resource allocation. Under control of the picture connection managing unit, the picture connection between the picture inputting unit and the picture outputting unit takes place through an allocated channel resource.
