Title: Information processor with joy stick
Inventor: TAKEMURA KENICHI
IPC: G06F3/038
Filed: 1992-06-24
Abstract: PURPOSE:To naturally move a cursor to a desired position as a user intends by optionally varying the proper moving speed of the cursor at a coordinate position based on the coordinate values and the displacement amount to a neutral position. CONSTITUTION:A remote controller 10 is constituted of the operation part 18 of the joy stick 13 for designating the movement direction of a cursor, a speed changeover switch 17 for selecting the moving speed oft he cursor, a 1st RAM 12 which stores input data, a 1st ROM 11 which stores a program or table controlling the operation of the remote controller 10, and a 1st central processing unit 16. The remote controller is rotated from the neutral position whose X and Y addresses indicate 0 in a positive, '1', or negative direction on all sides. The X and Y coordinate addresses indicating the coordinate values of a lever area are read out and the coordinate values and the displacement amount to the neutral position are calculated. The proper cursor moving speed at the coordinate position can optionally be varied based the displacement amount, so that operation is easily performed.

Title: Developing equipment and process cartridge and image forming device
Inventor: FUJITA AKIRA
IPC: G03G15/08
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent a toner leak by surely recovering undeveloped toner on a developing sleeve after development in the opening of a developing container. SOLUTION: In an area where undeveloped toner on a developing sleeve 5 is recovered, a sealing member 17 composed of a flexible sheet (SUS 304) is disposed so that its one end is fixed to a frame 18 and its free end, the other end is in frictional contact with the developing sleeve 5. The undeveloped toner is prevented from receiving electric field by which it is pulled and peeled in the direction of the sealing member 17, by applying a bias to it from a power source 20 as well as to the developing sleeve 5, thereby making the developing sleeve 5 and the sealing member 17 equal potential. Thus, the toner is prevented from leaking from the lower part of the developing sleeve 5.

Title: Force detector
Inventor: IZUMI KOJI
IPC: G01L5/16
Filed: 1986-07-15
Abstract: PURPOSE:To facilitate the manufacture of a strain generator by forming the flat plate-shaped object to be strained that is formed with a detecting surface between a central portion and a periphery both having a high rigidity, masking either the central portion or the periphery a supporting portion and the other a point of action and forming detecting elements on the detecting surface. CONSTITUTION:A supporting portion 4 and an acting portion 7 have a higher rigidity than that of a flat plate portion 8 and, furthermore, the supporting, acting and flat plate portions 4, 7 and 8, respectively, are integrally formed in a flat plate-shaped object 1 to be strained. Thus, a fixed portion and a load detector are connected to the supporting and acting portions 4 and 7, respectively, whereby neither hysteresis nor nonlinearity is generated. Although a strain is liable to be produced in a detecting surface 9 by a stress produced by a thread fastening 3 or the like in the supporting and the acting portions 4 and 7 as fastening portions, since the supporting and acting portions 4 and 7, respectively, have a far higher rigidity than that of the flat plate portion 8, the strain caused by the fastening of other members is not produced in detecting elements 14.

IPC: D06M13/285
Filed: 1983-09-09
Abstract: A textile treatment composition comprises a water insoluble quaternary ammonium salt and a non-ionic surfactant containing at least one long-chain alkyl or fatty acid substituent and a hydrophilic group. The quaternary ammonium compound preferably has three large alkyl substituents of at least carbon atoms each and the surfactant may be selected from phosphine oxides, sulphoxides, or tertiary amine oxides, especially the latter. The compositions may be diluted with water and applied to textile materials especially wool, to give antistatic properties thereto. Compositions of the invention have lower soiling propensity than hitherto available compositions and they may therefore be applied to finished carpets, either in the piece or in situ applications.

Title: Setting method for mechanical original point of numerically controlled moving object
Inventor: NISHIYAMA KIYOTAKA
IPC: G05B19/401
Filed: 1984-08-10
Abstract: PURPOSE:To improve the setting labor and time for setting an original point by providing a detection means for arrival of the original point position of a moving object so that its position can be freely controlled and then controlling the detecting position of the original point to a place shifted by a prescribed distance from the oscillating position of a zero pulse. CONSTITUTION:The moving action of a moving object 5 is caught by an encoder 1 of an incremental system, and a zero pulse detection signal is oscillated at a zero point slit 3a decided by a slit 3 of a slit disk 1. Thus the moving action of the object 5 is controlled. Here a dog 13 is provided with free control of its position to detect that the object 5 arrives at a prescribed position near an original point. Then the shift of the object 5 toward the original point is detected by a limit switch LS provided to the object 5 at both ends 13a and 13b of the dog 13. At the same time, the number of pulses are counted until the oscillation of said zero pulse. This counted number of pulses is compared with the number of pulses equivalent to half rotation of the encoder 1. The dog 13 is controlled to a position where the difference is equal to zero between both pulse numbers. Then an original point is set.

Abstract: PROBLEM TO BE SOLVED: To provide a vibration energy converter which converts a vibration energy into a power energy with a high conversion efficiency and with a simple construction. SOLUTION: A magnetic circuit in which a flux coming out of at least the one side pole 12 of a magnet 11 is divided and made to enter at least two yoke entrances through spaces S whose number is the same as the number of yoke entrances and which face the pole 12 and the divided fluxes coming out of the yoke exits are returned to the other side pole of the magnet 11 again is formed. Coils 15 interlinking the fluxes of the magnetic circuit are wound. Two or more yokes 13 are all rigidly and mechanically connected to each other. The lengths of the spaces which are distances between the pole 12 and the yoke entrances are elastically maintained by a mechanical spring system and the magnet 11 or the yoke 13 is directly connected to a vibration generating side.  If the space length is changed differentially in accordance with the direction of the division by a vibration, the division of the flux is differentially changed. With this constitution, a vibration energy can be taken out from the coils 15 wound on the yokes 13 and/or the pole 12 as an electric power.

IPC: B26F1/14
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To reduce the load of a driving mechanism and enhance a punching capacity by making up the tip form of a punch into a convexity that lowered both front and rear sides in a direction of rotation more than an intermediate part, and uniformizing the extent of punch hole cutting length per unit turning angle at an interval ranging from the starting time of fitting with a die to the time of complete fitting. SOLUTION: In a punching part 16, an upper punch turning shaft 17 and a lower die turning shaft 18 are set up in parallel with each other, and two punch holders 19 are installed in the center of the punch turning shaft 17 and both the symmetrical sides each. In addition, a die holder 20 is installed in the die turning shaft 18 at a position corresponding to the upper punch holder 19. A punch 21 and a die 22 are inserted into each mounting hole installed in each peripheral surface of the punch holder 19 and the die holder 20, and they are locked by a set screw. At this time, a tip end face of the punch 21 is made up into a convex form where both front and rear parts in a direction of rotation are inclined to the side of the turning center, and the front part is formed into a gentler incline than the rear part.  With this, punch hole cutting length per unit turning angle is uniformized and thereby a reduction in the load of a driving mechanism is promoted.
