An air conditioner and filtering unit produces a positive or negative pressure to create an isolation space. A common air intake plenum has first and second inlets for admitting return air from the space or outside air which may be from a building main A/C system supply. Sanitized, cleaned and conditioned air is returned to the conditioned space; and condenser air is exhausted outside the conditioned space. The air intake plenum may be common to both the condenser air flow and to the evaporator air flow. A HEPA filter cleans the air suppled to both the condenser and the evaporator. A slide damper or other arrangement selectively opens and closes air flow through the first and second air inlets into the common intake plenum. This permits creation of overpressure, underpressure, or an intermediate pressure in the conditioned space. All air supplied to the room and all air exhausted from the room is cleaned and sanitized. The unit is self-contained and portable.

In a semiconductor-device fabrication method, a plurality of recessed portions are first formed in the principal surface of a substrate. Then, a through hole, passing through the substrate in the front-to-back direction of the substrate, is formed under a portion of the bottom of each recessed portion in the substrate. Subsequently, a plurality of semiconductor elements in the form of chips are spread in a liquid, and the semiconductor-element-spread liquid is poured over the principal surface of the substrate, while passing the liquid through the through holes, so that the semiconductor elements fit into the recessed portions in a self-aligned manner. In this way, the semiconductor elements are disposed into the recessed portions in the substrate in a self-aligned manner.

The disclosed HPLC column is formed with overlying concentric inner and outer tubes. The flow path is established via the inner tube bore that holds packed absorbent, end filters and capping sealing members, and end coupling members cooperate with the inner tube at its ends. The sealing and end coupling members have conventional configurations for establishing a sealed connection with capillary lines and their fittings, for the series flow testing use through the column. The inventive method and manner of assembly provides that the outer tube overlies all of the inner tube and both sealing members, but only part of each end coupling member. The ends of the outer tube are then deformed radially inward to become mechanically interlocked with the end coupling members, as the column, holding also the filters and sealing members within the inner tube.

The present invention relates to a rotation angle detection device mainly used for rotation angle detection of a steering wheel of an automobile and the like.

In the rotation angle detection device of the present invention, support portions for supporting lower surfaces of magnets and retention portions for retaining upper surfaces of the magnets are provided in respective accommodation portions of first and second detection bodies. The magnets are turned in the accommodation portions, and the magnets are press-fitted into lower surfaces of the retention portions so as to be retained and fixed between the support portions and the retention portions. Thereby, an inexpensive rotation angle detection device in which the magnets can be easily and reliably installed in the detection bodies with a simple configuration without individually using holders can be realized.

The housing upper part has at least one actuating element and a contact spring. The contact spring has two contact legs connected by a back, and the lower housing part has a top spring has two spring legs and a back which connects the spring legs. When the housing upper part is pressed onto the housing lower part, the actuating element presses on the back of the top spring so that the top spring moves into a position such that the terminal lead is clamped between the contact legs.

A printed circuit board with an electronic component embedded printed circuit board and a manufacturing method thereof are disclosed. According to an embodiment of the present invention, the method of manufacturing a printed circuit board with an embedded electronic component having a groove formed on one surface thereof and an electrode formed inside the groove includes: forming a first circuit pattern on one surface of a first metal layer; pressing the first metal layer against a first insulator; forming a first conductive protrusion by selectively etching the other surface of the first metal layer; and mounting a first electronic component by disposing a conductive adhesive layer such that an electrode of the first electronic component and the first conductive protrusion are electrically connected to each other. Thus, an electronic component without its electrode protruded outward can be mounted easily and reliably and the manufacturing time can be shortened.

The invention relates to an angular position sensor for determining a relative angular position in relation to a reference position, comprising a housing (1), at least one rotor (3, 4) that is rotatably mounted in the housing (1), and a printed circuit board (2) that has electric and/or electronic components and one or more stators, corresponding to the number of rotors (3, 4).
