Disclosed is a method whereby a narrowed part similar to an actual lesioned blood vessel can be easily obtained. A mold (10) comprises first and second molded members (16, 17) having inner spaces (29, 40, 57) passing through in the axial direction and an axial member (18) detachably inserted through the individual inner spaces (29, 40, 57) of the individual molded members (16, 17). The molded members (16, 17) have tapered front parts (27, 27) respectively. In the state of facing the front ends (20) of the tapered front parts (27) to each other and thus forming a concave (12), the axial member (18) is attached. A first material (75) made of a mixed material comprising calcium carbonate or the like and silicone or the like is applied to the concave (12). A second material (76) such as silicone is applied to the entire outer periphery of the mold (10). After hardening the materials (75, 76), the mold (10) is withdrawn by detaching the axial member (18) and dividing the concave (12). Thus, a simulated blood vessel (78) having a simulated narrowed part of the blood vessel caused by calcification can be obtained.

A fermented tea produced by primary-drying tea material leaves by means of a primary tea rolling dryer (primary drying step) to adjust the moisture content of raw leaves (tea material leaves) of bancha with low qualities (the second crop of tea, the third crop of tea, the shuto-bancha, the skiffed leaves of tea, and the like) to a constant moisture; subsequently, providing them in a tea roller (tea rolling step); adding loquat leaves during the tea rolling step in order to knead loquat leaves together with the tea material leaves; and fermenting and drying the kneaded tea material leaves and loquat leaves. The fermented tea is formed into a composition having, as an active component, the fermented tea obtained by tea-rolling processing of tea material leaves and loquat leaves, and an extract contained in the fermented tea.

A refrigerant cycle device includes a compressor driven by a vehicle engine for drawing and compressing gas refrigerant from an evaporator, a variable displacement mechanism which varies a discharge capacity of the compressor based on a control value from an exterior to approach a suction pressure of the compressor to a predetermined suction pressure, and a control unit for controlling the discharge capacity of the compressor. The control unit includes a determining part for determining an accelerating state of the vehicle engine, a detecting member which detects a thermal load of the evaporator, a setting part for setting a minimum control value in accordance with the thermal load, and a controlling part. The controlling part reduces the control value to the minimum control value and returns the reduced control value to a control value before the reducing, when the determining means determines an accelerating state of the vehicle engine.
摘要:
The present invention provides a genetic engineering material for insects that enables a target protein to be purified easily, without requiring the use of recombinant baculovirus, while simultaneously providing a process for producing exogenous protein using that genetic engineering material. A gene recombinant silkworm is obtained by inserting an exogenous protein gene such as a cytokine gene coupled to a promoter that functions in silk glands into a silkworm chromosome. An exogenous protein such as a cytokine is then extracted and purified from the silk glands or cocoon of that silkworm or its offspring. A large amount of exogenous protein can be produced within silk gland cells, outside silk gland cells or in silk thread or a cocoon by inserting an expression gene cassette, in which the DNA sequence of the 3′ terminal portion and the DNA sequence of the 5′ terminal portion of fibroin H chain gene are fused to the exogenous protein gene, into silk gland cells and so forth.

A film of uniform thickness can be formed on the entire surface of a substrate. A processing solution supply apparatus includes: a nozzle provided with a supply hole for discharging a plating solution toward a processing surface of a substrate held in a substantially horizontal direction; a temperature controller for accommodating therein the plating solution in an amount necessary for processing a preset number of substrates, for controlling a temperature of the accommodated plating solution up to a preset temperature; a heat insulator disposed between the nozzle and the temperature controller, for maintaining the plating solution, whose temperature has been controlled by the temperature controller, at the preset temperature; and a transporting mechanism for transporting the plating solution, whose temperature has been controlled up to the preset temperature by the temperature controller, toward the supply hole of the nozzle via the heat insulator.

Locations of IC tags affixed to items are automatically recognized without requiring interrogators or antennas are allocated at respective inventory locations.To attain this object, interrogator 1 firstly transmits a unique ID readout command specifying read range, and corresponding IC tags 2a, 2b, 2c sequentially reply their unique IDs (Xa), (Xb), (Xc) respectively.At the same time, interrogator 1 transmits a probe signal send out command specifying ID, and corresponding IC tags 2a, 2b, 2c sequentially send out probe signals respectively.IC tag 2 that detects a probe signal with reception strength more than a predetermined level stores in its memory IDs (Xa), (Xb), (Xc) that interrogator 1 specified as adjacent ID.Then, interrogator 1 transmits an adjacent ID readout command specifying ID, and corresponding IC tags 2a, 2b, 2c sequentially reply adjacent IDs (Xb), (Xa.Xc), (Xb) stored in their memory respectively.Lastly, all possible combinations (Xa-Xb), (Xb-Xa), (Xb-Xc), (Xc-Xb) of unique IDs (Xa), (Xb), (Xc) and adjacent IDs (Xb), (Xa.Xc), (Xb) that controller 3 has collected via interrogator 1 are obtained and any identical combinations are excluded so that (Xa-Xb), (Xb-Xc) remain as final combinations, and the final combinations having one side in common are joined to produce a link pattern of ID information.Thus, it is understood that IC tags 2a, 2b, 2c exist in the same communication area B, and are arranged in order of 2a, 2b, 2c.
摘要:
When an upper arm of U-phase has failed because of short-circuit, lower arms of V-phase phase and W-phase as the opposite arms are switching-operated. When only the lower arm of V-phase is turned on, a route of motor current passing through an IGBT element from a V-phase coil is formed, and therefore, the motor current returning to the short-circuited phase decreases. Further, by the switching operation of the arm opposite to the short-circuited arm, an AC current is induced in a motor generator. Therefore, it is possible to continuously drive the motor generator while preventing increase in the current passing through the short-circuited phase, without adding a new device structure. This ensures running of the vehicle in the limp mode.
