Title: Vertically arranged device for squeegee for floor surface cleaner
Inventor: SHISHIDO OSAMU
IPC: A47L11/40
Filed: 1989-04-28
Abstract: PURPOSE:To enable moving a vehicle backward and the pulling-up working of a squeegee, to be performed easily and certainly with one touch by arranging the squeegee handle of a mechanism for enabling the pulling-up state of the squeegee to be retained, a handle for moving backward, and a motor switch for moving the vehicle backward. CONSTITUTION:When a squeegee handle 10 is rotationally moved to be pulled up to a position exceeding a dead point, then a squeegee 7 is pulled up from a floor surface, and its state can be retained. Besides, when a handle 11 for moving backward is pulled up to be rotationally moved in a state that the squeegee handle 10 is kept moved down, then the squeegee handle 10 is interlocked to be rotationally moved and the squeegee 7 is pulled up from the floor surface and in the meantime, the reverse rotation motor switch 15 of a running motor 2M is turned ON, and a vehicle 1 can 6e moved backward. Besides, when hands are separated from the handle 11 for moving backward, then by the tractive forces of springs 15, 17, both the handles 10, 11 are immediately reset in a state before they are rotationally moved. Accordingly, the motor switch 18 is turned OFF and the moving-backward of the vehicle 1 is stopped, and at the same time, the squeegee 7 is earthed on the floor surface again.

Title: Stem for semiconductor device
Inventor: MURAISHI HIROAKI
IPC: H01L23/48
Filed: 1981-07-17
Abstract: PURPOSE:To prevent discoloration due to the heat treatment applied when a semiconductor element is fixed on an eyelet, by applying die scalping to a wire rod with an Ni layer formed on the surface, and by using the same as an external connection terminal. CONSTITUTION:Ni plating 22 of 3-5 weight % is applied on the surface of a 42 alloy wire 21 having a diameter of 4mm., die scalping and annealing are then applied repeatedly, and thus a wire rod having Ni coating in the same quality with that of metal Ni is prepared. The rod is cut in a desired length and finished by heading processing. An external connection terminal prepared according to this constitution is not discolored when a semiconductor element is fixed on an eyelet, because of the presence of an Ni layer on the surface thereof. In addition, the rigidity of the wire rod is preserved and this facilitates the connection of the terminal to the eyelet by welding, since no heat treatment is conducted after final die scalping.

Abstract: PURPOSE:To prevent a cylindrical holder from the generation of movement or distorted deformation due to the contraction working of a laser welding part by performing laser welding near a position where the cylindrical holder is brought into contact with a holding block. CONSTITUTION:When a press screw 31 in a screw hole 30 is clamped down, the cylindrical holder 27 is pressed against the inner peripheral area of a cylindrical hole 26 arranged on the opposite side to a bottom surface 25 and fixed on the holding block 24. A portion shown by a mark (e) near the position where the cylindrical holder 27 is brought into contact with the holding block 24 is welded by laser beams so that the holder 27 is rigidly fixed on the block 24. Since the laser beam welding is executed on the position near the contact position of the holder 27 with the block 24, the holder 27 can be prevented from the generation of movement or distorted deformation due to the contraction working of the laser beam welding part. Since the holder 27 is pressed against the inner peripheral area of the hole 26, the laser beam welding can be easily executed without any failure.

Filed: 1988-05-10
Abstract: PURPOSE:To prevent base fogging by means of applying a sufficient bias voltage and to prevent deterioration in image density by providing one or more scraping members whose sides facing a magnet roller are formed irregularly and efficiently scraping toner and carriers. CONSTITUTION:Since the action of the scraping member 11, that is, an irregular spring 11b on the surface of a bar member 11a facing the magnet roller 4, surely scrapes away the toner and carriers attaching to the outer periphery of a sleeve 4b, base fogging can be prevented by applying a sufficient bias voltage. In addition, deterioration in the density of the toner on the magnet roller 4 can be evaded to prevent deterioration in image density. Moreover, the scraping member 11 can be produced inexpensively, and therefore the price of the developing device does not become expensive. When plural scraping members are provided around the outer periphery of the sleeve 4b and on the side opposite to a photosensitive drum 3, a toner scraping function and a carrier scraping function can be displayed simultaneously.

Abstract: PURPOSE:To surely feed the front end part of a photographic film to a film winding chamber by delivering a leader film which is connected to the front end of the film, is rigid and is broader than the film to a case body side only by the driving of a spool shaft. CONSTITUTION:The film cartridge 2 is supplied to a user in the state of retracting the front end of the leader film 7 as well into the case 3. A fork 20b engages with a key 5a on an upper side when the cartridge 2 is inserted to the prescribed position of a cartridge loading chamber 20 of a camera. The feed mechanism on the camera side operates when a rear lid 21 is closed. The spool shaft 5 is then driven counterclockwise via the fork 20b and a flange 10 is rotated as well, by which the leader film 7 is pushed out of the case 3 via the projection 11. While both end edges of the film 7 are guided to the tapered surface 23a of a leader passage 23, the film is inserted between a pressure plate 24 and the passage 23. Since the film 7 has rigidity, the film is fed while pushing up the pressure plate 24. The film is bent by a guide plate 29, is captured by a pawl 30 of a winding spool 28 and is thereby wound.
