Inventor: TAKAHASHI AKIRA
IPC: H01G4/12
Filed: 1990-01-31
Abstract: PURPOSE:To enable efficient and reliable application of conductive paste for forming an outer electrode even onto a small multilayer chip by cutting grooves, for separating into individual ships, into a laminate and then filling the grooves with the conductive paste thereafter cutting the laminate in the center of the conductive paste. CONSTITUTION:Grooves 11, 11... are cut, by means of a diamond blade 30, into a laminate 10 having rear surface being held by an adhesive tape 20. Conductive paste 12 is then applied on the cutting grooves 11, 11... and filled, therein. The conductive paste 12 is then baked and hardened. Cutting grooves 13, 13... are then made, by means of the diamond blade, in the center of the conductive paste 12. Consequently, the conductive paste 12 filled in the initially cut grooves 11 is separated from the opposite sides of the grooves 11, 11 by means of the later cut grooves 13. Thereafter, grooves 14, 14... are cut to separate the laminate into individual chips 50, 50.... According to this method, the conductive paste 12, 12 is applied accurately and simultaneously onto the opposite ends of a large number of multilayer chips 50, 50... and outer electrodes 15, 15 are formed.

Title: Rotor driving device and image forming device using rotor driving device
Inventor: OKUNO HITOKI
IPC: F16F15/30
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To suppress the influence of various vibrations generated by driving of a rotor using a small flywheel to a minimum by setting resonance frequency in a power transmission part so as to satisfy the specific relation of noise vibration frequency to the peripheral velocity of a rotor. SOLUTION: Resonance frequency of a driving system extended to photoconductor drums 41C-K through a worm 46, helical gears 48C-K and rotary shafts 47C-K is made fs (Hz), and the resonance frequency fs is set to satisfy an expression fs <fp /2<1/2> in order to damp noise vibration frequency fp (Hz) transmitted to the drums 41C-K. The displacement of an input shaft is therefore damped and transmitted to an output shaft. Resonance frequency of a shaft part from the drums 41C-K to flywheels 49C-K is made fn (Hz), and the peripheral velocity of the respective drums 41C-K is made V (mm/s) to set an expression 2<1/2> .V<fn . The external vibration of the drums 41C-K with the striped pattern easily recognizable can therefore be reduced by the inertia of the flywheels 49C-K.

Abstract: PURPOSE:To reduce the amount of data stored in the memory, by standardizating the radius data with the reference circle radius and memorizing the X, Y coordinate displacement data train between the adjacent two points of each train on the circumference of the reference circle. CONSTITUTION:ROM's 1, 2 store the X, Y coordinate displacement data train of dot train divided by N equally for the circumference of the reference circle Ro in radius. First, the data such as radius of arc, start point deflection angle, center angle, start point X, Y coordinates are entried in the registers 3, 5, 6, 7, 8 respectively. The content of the registers 7, 8 is transferred to the multipliers 12, 13, and the D/A converters 15, 16 output the X, Y deflection signal of arc start coordinate. Next, the radius control circuit 4 shifts the register 3, the content is taken as the normalized radius referencing the radius Ro, and the circuit 4 transfers the number of shifts m to the clock control circuit 14. The start point deflection angle is entried in the address counter 9, the displacement data from ROM's 1, 2 and the normalized radius from the register 3 are multiplied 10, 11 with the accumulation with the start point coordinate data 12, 13. This is repeated with the number of times set with the center angle, establishing the sircular arc signal.
