Abstract: A swivel working machine includes a swivel base, a prime mover installed in the swivel base, a working device provided at the swivel base, and a support mechanism that supports a fuel cylinder in a rotatable manner around a pivot shaft. The fuel cylinder contains fuel for the prime mover. The support mechanism includes a support rotating body that supports the fuel cylinder and that rotates around the pivot shaft, a rotational-position defining mechanism including a pin that defines a rotational position of the support rotating body around the pivot shaft, and an adjustment mechanism that adjusts a position of the pivot shaft relative to the pin.

Abstract: The present provides a biomaterial for repairing biological tissues, the biomaterial comprising: a water-soluble polymer having a reactive functional group A; and a cell having tissue-regenerating capacity and having, on the surface thereof, a reactive functional group B that can covalently bind to the reactive functional group A, wherein the biomaterial presents a hydrogel state when the reactive functional group A covalently binds to the reactive functional group B. Thus, the present invention can provide a biomaterial for repairing biological tissues that can exert excellent effect in repairing biological tissues by utilizing a hydrogel encapsulating cells having tissue-regenerating capacity.

Abstract: A working machine includes a machine body, an operation fluid tank mounted on the machine body, a hydraulic device to be operated by an operation fluid supplied from the operation fluid tank. A valve unit includes a plurality of control valves to control the hydraulic device. The control valves are arranged along a horizontal direction.

Abstract: A hybrid integrated circuit device is provided with: a microcomputer, a plurality of peripheral circuit elements, and a non-volatile memory which is positioned adjacent to the microcomputer, all of which are interconnected by a plurality of specified conductive paths; pair of integrated circuit substrates on which is formed the conductive paths and a casing provided with the pair of integrated circuit substrates secured to the upper and lower surfaces of the casing, forming a sealed space between these surfaces. The microcomputer and the peripheral circuit elements are positioned in the sealed space and only the non-volatile memory is positioned in an exposed space. The hybrid integrated circuit device of the present invention has a compact and simple form with a high degree of mounting density as well as superior handling capabilities and reliability.

Abstract: In a position closest to the mounting position of a microcomputer in a casing of a hybrid integrated circuit device on which is mounted the microcomputer and its peripheral circuit elements, an insertion hole is formed for a non-volatile memory which feeds data to the microcomputer. A socket for connecting the non-volatile memory is provided at the bottom of this insertion hole. Because of this configuration it is possible to connect the microcomputer and the non-volatile memory at an extremely short distance and the mounting efficiency of the integrated circuit device is increased. In addition, the non-volatile memory can detachably be mounted. Furthermore, the external shape of the insertion hole for the non-volatile memory is essentially the same as the external shape of the non-volatile memory so that when the non-volatile memory is inserted, the entire surface of this hybrid integrated circuit device is almost flat, providing excellent handling characteristics.
