A method and apparatus are provided which can automatically and securely supply a molding machine with natural resin pellets and masterbatch pellets at a predetermined mixture ratio, and which is excellent in performance and costs. A natural resin feeder and a masterbatch feeder are connected to a chute of the molding machine via respective tubes. The amount of the natural resin pellets and the amount of the masterbatch pellets which are air-transferred through the respective tubes are controlled such that they are transferred in accordance with the predetermined mixture ratio. The chute and the raw material supply port of the molding machine is connected by a pipe whose cross-sectional area at the upper portion is substantially equal to or smaller than that at the lower portion thereof. The natural resin feeder and the masterbatch feeder are intermittently operated in accordance with signals from an upper limit level meter and a lower limit level meter provided on the pipe.

A quantitative feeding apparatus usable for pulverized and/or granular material, a multi-colored automatic feeding apparatus in which the material to be handled is fed in the form of a master batch while the quantitative feeding apparatus is used therefor and a runner recycling apparatus are provided. At every time when the kind of color is to be changed to another one, it is necessary that the quantitative feeding apparatus using the master batch therefor is heretofore disassembled for the purpose of cleaning with the result that a number of manhours are consumed for cleaning operation. In view of the foregoing problem, a plurality of cleaning nozzles directed toward the upper feeding port of the quantitative feeding apparatus, the feeder and the bottom discharging part are arranged for the purpose of cleaning whereby automatic cleaning can be achieved satisfactorily.

In a belt buckle device including a tongue piece (75, 76; 210; 310) connected to an end of a belt extending in a longitudinal direction and a hook member (68, 70; 220; 320) configured to be selectively connected to the tongue piece by engaging a first lateral bar of the tongue piece in a hook opening (111; 226; 326) defined by a hook portion (71, 72; 225; 324) thereof, a longitudinal dimension (B) between the free end of the tongue piece and a base end side of the first lateral bar is substantially equal to or smaller than a width (A) of the entrance of the hook opening, and the effective thickness (C) of the first lateral bar is greater than the width (A) of the entrance of the hook opening. Thus, the first lateral bar is held inside the hook opening as long as the tongue piece is kept in a flat position in a reliable manner. In particular, the first lateral bar can be freely introduced into the hook opening simply by raising the base end of the tongue piece while the first lateral bar is applied to the entrance of the hook opening so that the belt buckle device can be readily fastened even when the belt buckle device cannot be viewed from a proper viewing angle. Also, the belt buckle device can be readily fastened with a minimum dexterity requirement and very quickly.

According to one embodiment, in an encryption device, a segmentation unit segments masked plain data into pieces of first segmented data. A first processing unit generates pieces of second segmented data from the pieces of first segmented data. A nonlinear transform unit generates pieces of third segmented data transformed from the pieces of second segmented data. A data integration unit integrates fourth segmented data to generate masked encrypted data. An unmask processing unit generates encrypted data from the masked encrypted data. The exclusive OR of the pieces of second segmented data matches the exclusive OR of input data, subjected to nonlinear transform processing and calculated from the plain data, and the first mask. The exclusive OR of the pieces of third segmented data matches the exclusive OR of transform data, obtained when the nonlinear transform processing is performed on the input data, and the second mask.

A battery system includes a battery block, a cooling pipe, and a coolant feeding device. The battery block includes a plurality of rectangular batteries that have a width greater than a thickness and are securely arranged in array alignment by a battery holder. The cooling pipe cools the rectangular batteries of the battery block. The coolant feeding device feeds coolant to the cooling pipe. In the battery system, the cooling pipe is arranged on the surface of the battery block in a thermally-coupled state so that the rectangular batteries are cooled by the coolant, which is circulated through the cooling pipe.

A walking assistance device including a pelvic frame (10) extending from a lower back to each lateral side of a user, and a belly belt (20) for securing the pelvic frame in position. A power generator (30) is attached to each lateral side of the pelvic frame. A power transmitting arm (40) can be attached to an output member (33) of the power generator simply by hooking an upper part of a base end (41) of the power transmitting arm onto an upper groove (38) of the output member, and pushing a latch member or a slider (46) provided in a lower part of the base end onto a lower groove (39) of the output member. The user wearing the pelvic frame (10) can easily attach the power transmitting arm (40) to the output end of the power generator (30) by easily using a single hand without requiring help.

A walking assistance device applies a walking assistance force from an electric motor to a femoral part of a user. The device comprises a communication unit and an operation switch enabling unit. The operation switch enabling unit disables an operation switch of the walking assistance device until the communication unit receives a signal from an external device even when a power switch is turned on, and enables the operation switch when the communication unit has received a signal from the external device while the power switch is turned on. Thus, unauthorized use of the walking assistance device is prevented, and operation of the walking assistance device is supervised with control parameters suited for the particular user. Also, the walking assistance device can be shared by a plurality of users, and each user can use the walking assistance device with pre-selected control parameters that optimally suit the particular user.

In a walking assistance device configured to apply a walking assistance force to a femoral part of a user, a walking assistance force provided by a power generator mounted on a pelvic support assembly is transmitted to a femoral part of the user via a femoral support assembly. The femoral support assembly includes a swing arm (60, 62) having a base end connected to an output end of the power generator and a free end opposing a front part of the femoral part of the user, a femoral support member (68, 70) pivotally connected to the free end of the swing arm and having a support surface engaging the front part of the femoral part of the user, and a femoral belt (73, 74) passed around the femoral part of the user and having two ends attached to corresponding lateral ends of the femoral support member. Thereby, the femoral support member is enabled to accommodate changes and/or variations in the contour of the femoral part of the user. Ensure a comfortable fit and a reliable power transmission, the femoral belt may include a main belt portion (83, 85) having a base end connected to one of the lateral ends of the femoral support member and a free end releasably connected to the other lateral end of the femoral support member, and an auxiliary belt portion (84, 86) bifurcated from an intermediate part of the main belt portion and having a free end connected to the swing arm.
