Abstract: A pair of right and left supporting bases (10) provided on a sidewalk (9) of a revolving body (4) and both right and left sides (16) of a movable ladder (12) are connected by trajectory restricting members (22) in a swingable manner. In positions of the left supporting base (10) which are apart from each other, main body base ends (20a and 21a) of first and second hydraulic cylinders (20 and 21) are pivotally supported, and rod tip ends (20b and 21b) of the respective hydraulic cylinders (20 and 21) are pivotally supported in a common position of the left side (16) of the movable ladder (12). By operating the first and second hydraulic cylinders (20 and 21) in directions reverse to each other (extension and retraction), in-common pivotally supported parts (20b and 21b) are moved, thereby switching a position of the movable ladder (12) between an extended position and a retracted position.

Abstract: The present invention provides a refrigerator with improved refrigerator box strength and high heat insulating performance, which is configured such that external deformation due to entry of air into a vacuum heat insulating material, the entry of air being caused by aging degradation, is prevented. The present invention includes: a heat-insulated box including an inner casing and an outer casing, in which space between the inner casing and the outer casing is filled with a foamed heat insulating material; and a vacuum heat insulating material disposed in at least a side wall of the heat-insulated box together with the foamed heat insulating material, the vacuum heat insulating material including an outer skin material, the outer skin material including at least a core material and being decompression-sealed. The vacuum heat insulating material includes a gas adsorbent.

Abstract: To provide a cancer pain therapeutic and/or prophylactic agent which can be administered to a patient for a long period of time from the early stage to the final stage of the cancer pain therapy, instead of conventional non-opioid analgesic agents or opioid analgesic agents. The cancer pain therapeutic and/or prophylactic agent containing, as an active ingredient, a 1,5-benzodiazepine derivative represented by formula (1): (wherein R1 represents a C1-6 alkyl group, R2 represents a phenyl group or a cyclohexyl group, and Y represents a single bond or a C1-4 an alkylene group) or a pharmaceutically acceptable salt thereof.

Abstract: A bottom-freezer refrigerator comprises a generally rectangular box-like refrigerator housing including a top division and a bottom division with an adiabatic partition wall intervening between the top and bottom divisions. The top division has a refrigerator chamber and a crisper chamber both defined therein. The bottom division has a freezer compartment defined therein. The bottom-freezer refrigerator of the structure described above also comprises a first cooler provided in the top division at a location spaced from a rear wall portion of the crisper chamber, a first circulating fan disposed in the vicinity of the first cooler, a second cooler provided in the bottom division, and a second circulating fan disposed in the vicinity of the second cooler. The refrigerator chamber and the crisper chamber are cooled by the first cooler in cooperation with the first circulating fan, whereas the freezer compartment is cooled by the second cooler in cooperation with the second circulating fan.

Abstract: A refrigerator has a refrigerator compartment, a freezer compartment, and a low-temperature storage chamber formed in the refrigerator compartment and having a temperature lower than that of the refrigerator compartment. The refrigerator includes a compressor, a condenser, a first throttling device, a channel control valve, a refrigerator cooling unit, and a freezer cooling unit connected in series to form a refrigerating cycle. The refrigerator cooling unit and the freezer cooling unit are accommodated in the refrigerator compartment and the freezer compartment, respectively.
