Abstract: A refrigerator has a blowing fan being capable of blowing bilaterally in a cool air duct. When a door is opened, the blowing fan blows to discharge cool air from the cool air duct, so the air curtain for shutting off a cooling compartment is generated. When the door is closed, the blowing fan blows to draw cool air in the cooling compartment into the cool air duct, so the circulation of the cool air is actively performed, and the cooling efficiency is enhanced.

Abstract: A document original simulator including first tone simulation portion having substantially the same reflectance as a white original sheet and a second tone simulation portion having a lower reflectance than the first tone simulation portion. When an image fogging detecting operation is to be performed with the use of the document original simulator, it is checked whether or not the amount of light reflected from the first tone simulation portion when the first tone simulation portion is illuminated with light is smaller than the amount of light reflected from the white original sheet placed on a document original presenting section when the white original sheet is illuminated with light.

Abstract: A cut is made in the neck of slaughtered poultry to permit access to a tool for removing the crop. The cut is made by an apparatus which includes a carousel for moving the poultry, arch-shaped tracks which have sections which are horizontal, upward-sloping and downward-sloping, and running wheels which move in the tracks to effect vertical movement of handling units and bird positioning units. Each handling unit includes a tilting arm which has a blade fitted at its upper end, a centering fork with two centering elements which contact opposite sides of the neck of a bird, and a running wheel at its lower end where the running wheel rides in a track. During movement of the running wheel on its track, the tilting arm is first tilted from its sloping non-operative position to a less sloping vertical position to center the neck of a bird and to bring the blade against the neckskin, and the arm then makes a downward movement to form a cut in the neck.

Abstract: A vacuum cleaner includes a dust sensor of the light emitting and light receiving type, which sensor detects the quantity of dust which is sucked during a cleaning operation. The vacuum cleaner also includes a sensitivity correction section which compensates for lowering of the dust detection sensitivity due to soiling of the dust sensor, a limit detection section which detects a condition in which the compensation of dust detection sensitivity by the sensitivity correction section reaches a limit value, and an information section which informs the vacuum cleaner user of the condition in which correction of the dust detection sensitivity by the sensitivity correction section has reached its limit value.

Abstract: A device for weighing elongated members such as marine lines and ropes includes a hub, a motive wheel which is supported on the hub and is driven by a motor, and a driven wheel which is coupled to and driven by the motive wheel. The motive wheel and the driven wheel respectively form opposite sides of a groove for receiving the elongated member which is being weighed. A thrust ring is fixed to the driven wheel, and the motive wheel lies axially between the thrust ring and the driven wheel. The axial position of the driven wheel relative to the motive wheel is controlled by an idler roll which bears against the thrust ring and is adjustably mounted on the hub.

Abstract: Principal components of an automobile driving system for a two-wheel drive vehicle including a torque converter, a belt-type variable-speed transmission, a front differential gear, a transmission case containing these components, a front drive shaft included in a transfer unit, a double-pinion planetary gear, a fixed shaft, a first friction coupling element and a second friction coupling element can be used as the principal components of an automobile driving system for a four-wheel drive vehicle. The automobile driving system for a four-wheel drive vehicle can be constructed by additionally incorporating third, fourth and fifth friction coupling elements, a rear differential gear and a power transmitting mechanism for transmitting power to the rear differential gear into the automobile driving system for a two-wheel drive vehicle.

Abstract: The present invention relates to a process for the production of five-membered or six-membered cyclic ethers, in particular of anhydropolyols, by acid-catalysed cyclodehydration of polyols that contain at least two hydroxyl groups with a spacing enabling ring formation--that is to say, preferably with a spacing of 4 or 5 C atoms. The invention is directed in particular towards the production of anhydrotetritols, anhydropentitols and, particularly preferred, anhydrohexitols, from tetritols, pentitols and hexitols, respectively.

Abstract: A substrate transporting and processing system generally comprises: a supply section of a carrier 1 for housing therein wafers W to be processed, in a horizontal state; a discharge section of the carrier 1; a wafer unloading arm 14 for unloading the wafers W from said carrier 1; a wafer loading arm 16 for loading the wafers W into the carrier 1; an attitude changing unit 40 for changing the attitude of the wafers W between a horizontal state and a vertical state; a processing section 3 for suitably processing the wafers W; and a wafer transport arm 56 for delivering the wafers W between the attitude changing unit 40 and the processing section 3 and for transporting the wafers W into and from the processing section.

Abstract: The subject matter relates to a computer peripheral power distribution device, comprising a PC, a keyboard and a scanner, wherein one of the USB ports of the PC is connected by a USB wire to the USB control and microprocessor of the scanner; the keyboard is connected by a transmission cable respectively to the PC and the motor control and step motor of the scanner, thus by such connection, the working power for said scanner may come from the power transmitted from the PC through the USB port and the keyboard, so that it will not only eliminate the installation of a DC converter within the scanner, but will also reduce its total weight, and achieve the purposes of reduced power consumption, convenient portability and reduced costs.

Abstract: Handles for cutting instruments such as scissors are described, each handle being made of a relatively rigid plastics material and being provided in its finger-receiving hole portion (8;8') with a lining ring (15;15') of elastically deformable material, such as natural or synthetic rubber. Such elastically deformable ring permits the scissors to adapt itself to the fingers of the user, independently of their size or whether the user is right- or left-handed.

Abstract: A recycle document feeder according to the present invention includes a pair of document width regulating guides (9a, 9b) for guiding opposite edges of document originals (D) fed back onto a document placing plate (8) for alignment thereof with respect to the width thereof. With this construction, if the document width regulating guides (9a, 9b) each had a small length (A) as measured along a document transportation direction, the document originals (D) fed back onto the document placing plate (8) could not properly be aligned by the document width regulating guides (9a, 9b) thereby to be randomly stacked on the skew with respect to the document transportation direction.

Abstract: A method for supplementing fresh water into a boiler, which can effectively exhaust air from a pipeline circuit connected with the boiler, is disclosed. The method includes the steps of: a) determining whether a supply of the supplementary water into the boiler is completed; b) operating a circulation pump with a first operation manner for a first predetermined period when the supplementation of the fresh water is completed; and c) operating the circulation pump with a second operation manner for a second predetermined period after the first predetermined period passes. Therefore, the air, which has flowed into the pipeline circuit when the supplementary water was supplemented into the boiler, is effectively exhausted.
