Title: Developing device
Inventor: OKANO TADASHI
IPC: G03G15/08
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To uniformly form the thin film of triboelectrostatically charged developer with a simple configuration, to obtain a high-definition image and also to accomplish the miniaturization of the device and the cost reduction. SOLUTION: A friction control member 3 is bent in parallel to the rotary shaft direction of a developer carrier 1, and one surface of the member 3 is brought into press-contact with the developer carrier 1, the other surface of the member 3 is supported by a supporting member 9. Besides, the bent ridge 8 of the member 3 is arranged so that one plane of the ridge supporting member 91 may come into contact with the ridge 8. By bending the member 3 and sorting the press-contact surface with the developer carrier 1 from the supporting surface to the supporting member 9 and arranging the bent in such a way, the surface accuracy of the contact surface with the member 3 of the supporting member 9 is hardly effected on the surface accuracy of the press contact surface with the developer carrier 1 of the member 3.  Thus, high accuracy machining for improving the surface accuracy of the contact surface with the member 3 of the supporting member 9 is unnecessitated.

Title: Electromagnetic suction valve
Inventor: WADA TSUKASA
IPC: F16K31/06
Filed: 1985-06-29
Abstract: PURPOSE:To enable a timing at which a suction port closes to be changed readily, by closing the suction port by moving a valve body by a valve rod actuated by an electromagnetic solenoid. CONSTITUTION:When a piston 1 lowers to the lowermost point for pushing a pad 11 by a push rod 4, the pad which has been pressed from its under side is abruptly released and the pad 11 and a valve rod 14 lower downward so that a suction port 18 is opened. When an electromagnetic solenoid 13 is turned on after a certain period of time lapse, the valve rod 14 and the pad 11 are lifted upward for closing the suction port 18. At this time, since the force applied to the pad 11 and the valve rod 14 is only gravity and no force caused by fluid pressure is applied thereto, the suction port 18 can be actuated by small force. Only a change in a timing for turning on the solenoid 13 can change a timing at which the suction port 18 is closed.

Title: Thread cutting device
Inventor: YAZAWA MASAYUKI
IPC: B26F3/08
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To easily melt cut a thread securely preventing dust generation from the thread end, and preventing damage of cloth even if a heating element contacts cloth in unusing time by providing a switching means to energize the heating element by approaching each one end of the first and the second holders each other. SOLUTION: A spring 16 is fixed to each the other end of the first and the second holders 1, 11, and a predetermined clearance is secured between a thread receiver 15 and the heating element 7. A thread to be cut is positioned between both ends of a receiver 12. In the state shown in the figure a switching means 9 is in the OFF condition. The first and the second holders 1, 11 are grasped with a hand, and approaching the thread receiver 15 by the heating element 7 produces the ON condition by moving a contacting piece 9a which has been contacting the second holder 11 to heat up the heating element. The heating element 7 is made to approach the thread receiver 15 to nip the thread. Since a sewing thread used for dustproof clothes usually uses chemical fiber such as polyester, which melts at about 250 deg.C, the nipped thread is heated to be cut easily.

Filed: 1995-05-18
Abstract: PURPOSE: To obtain a method for directly measuring the dislocation density on the (100) face of a II-VI compound semiconductor crystal including ZnSe being expected as a material of blue light emission device. CONSTITUTION: A II-VI compound semi-conductor crystal is sliced on the (100) face thereof to obtain a single crystal substrate of ZnSe, for example, which is then subjected to surface polishing and mirror face etching. The ZnSe substrate 5 is placed in a Teflon basket 2 which is then set into 0.1vol.% bromine methanol solution 6 in the reaction bath 1 of a single crystal substrate etching system. Subsequently, etching is performed by turning a stirrer 3 disposed on the bottom of the reaction bath for a predetermined time by means of a magnetic stirrer 4. The ZnSe substrate is then observed by means of a Nomarski microscope and the dislocation density is measured from a clear etching image thus obtained.

N magnets 13 are corresponded with respective Hall elements 4 to 1:1, and the N magnets 13 are fixed to the columnar parts 12 so that they can be opposed to the corresponding Hall elements 4. The columnar part 12 is fitted to the cylindrical part 3 while interposing an elastic body 20 between the cylindrical part 3 and the columnar part 12. By moving the mouth, the elastic body 20 is deformed and the outputs of the N Hall elements 4 are changed. The size and direction of the force activating the mouth can be calculated from the outputs of the N Hall elements 4. Instead of a magnetic type gap sensor consisting of the magnets and the Hall elements, the gap sensor in other type can be used.

In the former case, the sign of the number held in the 1st register 4 is inverted and is used as the sign of the product.

Later, the fourth layers 8 are formed vapor- depositing the superconductive material in the arrow 7 direction. Through these procedures, the thin film region 4a not covered with the layers 4, 5 and 8 is formed so as to form a Josephson junction. Finally, a coated layer 9 comprising normal-conductive material or semiconductor can be formed on the fourth layers 8 and the thin film region 4.
