Abstract: A driving force transmitting apparaus having a rotation drum which is driven by a drive shaft and which is rotatable relative to a driven shaft and a rotation member which is fixed on the driven shaft and transmit driving force from the drive shaft to the driven shaft is disclosed. The rotated drum has an outer peripheral surface contacting a friction pad attached to the rotation member. Driving force is transmitted from the drive shaft to the driven shaft through the drum, the friction pad and the rotation member.

Abstract: A pressure developing device in an image recording apparatus for recording an image on the recording medium, includes a pair of pressure developing rollers to be separated from and contacted with each other, and a pressurizing unit disposed on either one of the pressure developing rollers for pressurizing one of the pressure developing rollers toward or away from the other of the pressure developing roller. A pressure control unit controls the pressurizing unit in such a fashion that one of the pressure developing rollers is placed in contact with and pressurized against the other of the pressure developing rollers under a plurality of pressure conditions by the pressurizing unit so that the pressure strength between a pair of pressure developing rollers is gradually decreased from the center to the ends along the axial direction of the developing rollers.

Abstract: Alpha-glucosidase inhibitor is provided as a promoter of calcium absorption in mammals. The examples of the inhibitor are shown by the formula; ##STR1## wherein A stands for a C.sub.1 -C.sub.10 acyclic hydrocarbon group which may be substituted by hydroxyl, phenoxy, thienyl, furyl, pyridyl, cyclohexyl or phenyl group which itself may be further substituted, a C.sub.5 -C.sub.6 cyclic hydrocarbon group which may be substituted by hydroxyl, hydroxymethyl, methyl or amino group, or a sugar residue.There is also provided a calcium preparation which contains an .alpha.-glucosidase inhibitor and a calcium source.

Abstract: An image recording apparatus using a microcapsule sheet on which a latent image is formed. The microcapsule sheet is accommodated within a sheet roll cartridge detachably provided to a main frame, and a take up means for winding light-exposed microcapsule sheet thereover. The cartridge and the take-up means are geometrically positioned at an upper portion of the main frame, so that these are easily assembleable and disassembleable. Preferrably, a link mechanism is provided which connects a cover member to the cartridge. The link mechanism provides disengagement of the cartridge from the main frame upon opening of the cover member, and provides an engagement therebetween upon closing thereof. Further, additional link mechanism is provided between the cover member and a separation roller unit. The separation roller unit is moved to a first direction where the roller is separated from the microcapsule sheet when the cover member is opened.

Abstract: An image recording apparatus for forming a latent image on a photosensitive pressure sensitive sheet and for developing the latent image on a developer sheet. The apparatus includes an exposure unit and a developing unit positioned close to each other. The apparatus also includes an optical system for irradiating light onto an original and directing the light reflected at the original toward the exposure zone. The original has an original image facing downwardly, and the photosensitive sheet has an imaging surface facing downwardly at the exposure zone. The optical system provides a U or J-shaped optical path extending from the original to the exposure zone. The optical system has reflection mirror unit vertically movably secured to a pair of frames of the apparatus. The frames are reinforced with a partition member which also functions as a light shielding member.

Abstract: In order to adjust light components, there is provided a filter unit which includes a light source for emitting a light, a filter housing to which an opening is formed; and three filters arranged in vertical direction within the filter housing and adapted to be drawn from the opening. Each of the three filters adjusts one of red, blue and green components contained in the light. A drive unit is further included in the filter housing which selectively draws the three filters from the opening to an optical path. Accordingly, the light components can be adequately adjusted by drawing the filters in the optical path. By the employment of such a filter unit in a color image recording apparatus, the color tone of the image reproduced in a copy sheet can be adjusted.

Abstract: In an image recording apparatus, a pair of support plates are provided in spaced-apart relation and in parallel to each other for rotatably supporting guide rollers for conveying a recording sheet, and a cartridge shaft around which the recording sheet in elongated, web-like form is wound. An outer casing is further provided which accommodates the support plates together with all components necessary for image recording. The casing has one wall arranged in the direction orthogonal to the surfaces of the support plate. A window is provided in that wall to facilitate maintenance of the apparatus.

Abstract: A device for preventing injury to the fingers of a person holding a cap into which an injector needle is inserted after use. The device is formed as a plate shaped member having a plane substantially transverse to the axis of the tube and having an area large enough to stop movement of the needle is not properly inserted into the cap when capping the injector. The plate member is provided with a thin-walled portion having a central opening and/or axial slits having inner edges which are elastically flexed and thus maintan a tight grip on the outer surface of the cap. Accordingly, the plate member is firmly fixed to the cap, and prevents injury to the fingers of a person holding the cap, by the needle, of the injector.

Abstract: Rapidly cured polyurethane elastomers are prepared by mixing a diphenylmethanediisocyanate based liquid prepolymer obtained from polytetramethylene ether glycol and an aliphatic diol at specified proportions, and a curing agent essentially containing said polytetramethylene ether glycol, diol and organometallic catalyst.

Abstract: A read only-memory (ROM) is manufactured by a process which produces memories having customized codes from partially completed semiconductor chips. The chips are manufactured to a step where a matrix of apertures or windows are formed in an oxide layer at every cross point of every potential code. Then, a silicon dioxide film is formed over the entire surface of the chip including the window apertures. At this stage, the chip is stored as a general purpose stock item. When an order is received to prepare a ROM chip with customized codes, a mask is formed to etch and reopen the apertures or windows in the dioxide film at the encoded cross points. Then, suitable contact material is deposited over the surface of the chip, thereby completing a contact at each of the reopened apertures or windows. As a result, the normal lead time required for a manufacturer to make a customized ROM is reduced from, say, 4.5 to 6 days to a period of approximately 1.5 to 2 days.
