Title: Electrically conductive ball mounting device and mounting method
Inventor: SAKAI TADAHIKO
IPC: H01L21/321
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To provide an electrically conductive ball mounting device and its mounting method in which a bump can be formed on an electrode by bringing an electrically conductive ball into contact with the electrode to make self- alignment even when an electrically conductive ball is largely displaced from the electrode. SOLUTION: Solder balls 3 which are electrically conductive balls provided in a supply part are picked up into adsorption holes 19 in the lower surface of a head 20 by vacuum adsorption and transferred toward works. On the way, an up-and-down operation is applied to the head 20 to press the solder balls 3 against the upper surface of a jig 13, and the lower surface of the solder balls 3 is flattened into a plate, and after that, the solder balls 3 are mounted on the electrode of the work. Since the lower surface of the solder balls 3 is flattened, the contact area to the electrode becomes large. Accordingly, even when the displacement of the solder balls 3 is large, the solder balls 3 can be brought into contact with the electrode, and therefore, a bump can be formed on the electrode by self-alignment at the time of melting the solder balls 3 in a heating furnace and forming the bump.

Inventor: SUMIYAMA MASAHIDE
IPC: H04R9/02
Filed: 1989-09-11
Abstract: PURPOSE:To attain high fidelity reproduction and high linearity in the view point of a characteristic by constituting the constitution of a damper of radial direction thread and circumferential direction thread, and in addition, using elastic thread in a radial direction and hard and strong thread in a circumferential direction. CONSTITUTION:The speaker is constituted by holding a voice coil 27 at a center by the damper 28 obtained by pressing cloth constructed by plain weave by arranging the radial direction thread 31 and the circumferential direction thread 32, and coupling it to a magnetic gap 29 so as to be fitted in the magnetic gap, and bonding a dust cap 30 to the surface of the connecting part of a diaphragm 26 to the voice coil 27. Here, such the constitution that the elastic thread, for instance, every soft polyimide resin fiber thread is used for the radial direction thread 31 in order to attain the high linearity of a speaker is adopted. Besides, as for a means to reduce the defect of the gap due to the occurrence of a rolling phenomenon, it can be dealt with by using the hard and strong thread for the circumferential direction thread 32.

Title: Recording and reproducing device for magnetic tape
Inventor: TESHIROGI KAZUHIRO
IPC: G11B15/46
Filed: 1992-09-03
Abstract: PURPOSE:To perform reproducing while speedily matching the phase of a regenerative signal with a reproducing reference signal by calculating tape running speed error from the change of phase difference between the internal reproducing reference signal and the synchronizing signal or address signal of the regenerative signal. CONSTITUTION:At the time of reproducing, speed error data 205 from tape running speed at the time of recording are calculated from the change of phase difference data 204 between an internal reproducing reference signal 201 and the synchronizing signal or address signal of a regenerative signal 202 and successively fed back to a driving circuit 5, and the phase error difference data 204 are fed back to the driving circuit 5. Thus, even when the difference of tape running speed at the time of reproducing from tape running speed at the time of recording is large, the phase of the regenerative signal 202 can be matched with the reproducing reference 201 speedily before the operation of phase detection is reset.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium which can prevent the excessive oxidation of a magnetic film surface layer and to improve high-frequency signal output characteristics, apparatus for producing the medium and an apparatus for its production. SOLUTION: A crucible 12 is irradiated with an electronic beam 14 from a piercing type electron gun 13 in the state that a base film 7 travels along a cooling can roll 6 to melt and evaporate a magnetic material 11, such as cobalt Co. The evaporated cobalt Co is made incident on the base film 7 and is adhered thereto. On the other hand, oxygen gushes from an oxygen nozzle 9. The cobalt oxide CoO is, therefore, formed as a magnetic film on the base film 7. Next, when the base film 7 arrives at the portion of a slit 20 of a contamination proof plate 8, the cobalt Co evaporated from the crucible 12 is deposited by evaporation and the magnetic layer of a low oxygen concentration is formed.

Title: Elevator parking (elpa)
Inventor: ITAGAKI SANEHIRO
IPC: E04H6/18
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To park a large number of bicycles in a small space by parking the bicycles in a bicycle-parking tower through the use of an elevator. SOLUTION: A plurality of elevators are arranged in an elevator parking tower. The elevator employs a method which is different from conventional ones. More specifically, front and rear doors are opened/closed, and the elevator preferentially stops on a floor for which a switch is firstly pushed. The manual door is automatically closed through the function of a sensor when no one is present therein. The remaining acceptable number and weight are displayed, and therefore the user can determine whether the number and weight of himself and his bicycle calculated beforehand exceed constant values, respectively. Further, rush hour operation in the morning is carried out so as to cancel congestion according to a simulation. Thus, the large number of bicycles can be parked in the bicycle parking tower under good locational conditions, such as an area near a station.

Filed: 1987-09-19
Abstract: PURPOSE:To stabilize contact by providing a member sandwiching a wiring duct from the opposing sides in a state that a plug blade and a frange are inserted inside the wiring duct. CONSTITUTION:A plug 50 for a wiring duct has gears 58 with levers 52 at the lower positions of plug fixing boards 55 on the opposing ends of a plug main body 51. The levers 52 turn to left and right within the angle of 90 degrees and protrude outside from the side of the main body 51. The gears 58, 58 are toothed at the portions having 90 degrees or more and meshed with similar gears 59, on which plug blades 54b, 54c are coaxially mounted. The blades 54b, 54c rotate in the same direction as the rotating direction of the gears 59 shown by an arrow. Plug fixing boards 55, 55 are mounted on the gears 58, 58 so that they may coaxially rotate, and the plug fixing boards 55, 55 are rotated in the same direction shown by arrows. It is thus possible to stabilize contact, since the plug insertion port of the wiring duct is not widened even if larger contact pressure is appllied by the plug blades 54b, 54c.

Title: Driving method for fluorescent display tube
Inventor: OCHI OSAMU
IPC: G09G3/20
Filed: 1992-09-04
Abstract: PURPOSE:To solve a problem of power consumption due to the fact that the whole grids are always set at on-potential and to prevent the electronic radiation capability of a filament from being degraded in a statically driven fluorescent display tube. CONSTITUTION:This method is a driving method in which the grid is divided into plural parts according to the patterns of phosphor segments 6-11 on the anode substrate of the fluorescent display tube 5, and the application voltage of the grid when all the phosphor segments 6-11 in the grids 12-14 go to off- potential is set as the off-potential. Thereby, the current on the grid can be reduced by the share of time when the grids 12-14 go to the off-potential, and also, power consumption can be reduced, and a degree of deterioration of the electronic radiation power of the filament can be decided based on the amount of electrons and the time of electronic radiation drawn by potential difference between the temperature of the filament and the grid, however, the period of time of electron emission per unit hour can be decreased, and the electron emission capability can be prevented from being degraded by such driving method.
