Abstract: A powder spray device includes a funnel member, a first three-way joint, an air-current supply tube, a discharge tube, a vibration motor, a bypass air-current tube, and a switching mechanism. The first three-way joint has a first opening connected to an outlet at a lower end of the funnel member. The air-current supply tube and discharge tube are respectively connected to second and third openings of the first three-way joint. The vibration motor is fixed onto an outer surface of a funnel body of the funnel member. The bypass air-current tube branches off from the air-current supply tube and is connected to the discharge tube. The switching mechanism switches from and to standby state, in which compressed gas is sent only through the bypass air-current tube, to and from spray-coating state, in which compressed gas is sent out through the air-current supply tube, and also through the bypass air-current tube.

Abstract: A sheet-shaped tissue adhesive/reinforcement includes a base sheet having biodegradability and a communicative porous structure, and an adhesive resin layer fixed and formed on the base sheet. The adhesive resin layer includes a first reactant made of an aldehyded glycan and a second reactant made of partially carboxylated polylysine, and has a molar ratio of 1 as a ratio of an aldehyde group of the first reactant to an amine group of the second reactant. The adhesive resin layer has a structure of granules derived from powder of the first reactant, and a connecting layer derived from the second reactant. The connecting layer connects the granules to each other and fixes each of the granules onto the base sheet, throughout the sheet-shaped tissue adhesive/reinforcement.

Abstract: Organic thermistor devices are produced by a first step of molding an organic thermistor material by covering a plurality of electrically conductive members to form a conductor-containing member, which is elongated in a longitudinal direction, has a pair of mutually oppositely facing side surfaces, having the conductive plates buried parallel to one another inside the organic thermistor material, each mutually adjacent pair of these conductive members being externally exposed on different ones of the side surfaces, a second step of forming a pair of electrodes elongated in the longitudinal direction on the side surfaces of the conductor-containing member, and a third step of thereafter cutting this conductor-containing member transversely at specified positions so as to divide into individual units.

Abstract: An organic thermistor device has a pair of outer electrodes formed facing each other on end parts of a thermistor body made of an organic thermistor material. Metallic wires extend inside and through the thermistor body transversely to the direction in which the outer electrodes face each other such that the resistance value at normal temperatures of the device can be significantly reduced. Both exposed surfaces of the thermistor body not covered by the outer electrodes and exposed end surfaces of the metallic wires not covered by the thermistor body may be all covered by an electrically insulating layer. To produce such organic thermistor devices, an elongated wire-containing member is prepared by molding an organic thermistor material by covering metallic wires extending longitudinally parallel to one another. It is then entirely covered with an electrically insulating material but portions of it are removed from a pair of longitudinally continuous external peripheral surface areas.

Abstract: A pumping circuit for a semiconductor laser is formed by connecting a semiconductor laser in series with a positive temperature coefficient (PTC) thermistor element which has a temperature coefficient in the range between −1.5%/° C. and −0.5%/° C. within the temperature range between −20° C. and +70° C. and of which the temperature coefficient becomes positive at a temperature over +70° C. A resistor insensitive to temperature changes may be further connected to the PTC thermistor element either in series or in parallel. The semiconductor laser and the PTC thermistor element are disposed sufficiently close to each other so as to be thermally coupled inside a container such as a can to form a semiconductor apparatus.

Abstract: A recorder motor with an encoder, for forming an image on a record medium in accordance with image information, has the encoder on the outside of the motor case and a plastic dust-proof cover for the encoder mounted on the case. Thus, contamination by dust or ink mist is prevented, and stable and high precision motor rotation is maintained.

Abstract: An automatic exposure device for obtaining X-ray pictures with superior quality and constant contrast by feedback of both tube voltage and tube current according to the residual X-ray dose which penetrates the body of a patient. This device is further characterized in that the feedback control is compensatingly done according to the changes in the tube voltage and tube current caused by fluctuations of the power supply.

Abstract: A mandibular motion reproducing device wherein a mandibular model supporting plate on which a mandibular model is fixed is deemed as a rigid plane, three points contained in this rigid plane are selected and marked, three reference points for reproduction are set each corresponding to one of the marked points and in a predetermined dimensional relationship therewith, drive means capable of shifting the individual reference points for reproduction along the coordinate axes of X, Y, Z respectively are connected therewith, the drive means have six alternative driving directions including the orthogonal X, Y and Z directions and are individually driven by inputting position coordinate information obtained from a measuring system and the resulting motions of the reference points for reproduction are synthesized for causing the rigid plate constituting the mandibular model supporting plate to undergo three-dimensional motion.
