Then an SiO2 insulating film 13 is formed over the whole surface of the substrate 11 by a CVD method and a hole 14 for contact with a bump electrode is formed in the film 13 on the Al electrode 12 by etching with fluoric acid. Then a current film 15 is formed over the whole surface of the substrate by electroless plating. After that, resist is applied to the whole surface and the resist on a bump electrode forming part only is removed to form a plating resist layer 16. Then the current film 15 is connected to a cathode and electroplating is applied in bump plating solution to form a bump electrode 17.

IPC: G03G15/04
Filed: 1988-10-21
Abstract: PURPOSE:To obtain the scanning device of a simple constitution with good accuracy by rolling two or more 2nd moving frame driving pulleys and two or more friction rolls on a friction plate by a toothed belt and then moving the 2nd moving frame at a specific slower speed than a 1st moving frame. CONSTITUTION:More than two friction rolls which rotate integrally with the 2nd moving frame driving pulley 7 are provided, so the friction rolls 8 serve as a slider and the friction plate 11 serves as a slider rail. Therefore, the 2nd moving frame 2 is moved stably as compared with the constitution of one 2nd moving frame driving pulley 7 and one friction roll 8 rotating integrally with it without providing a slider not a slider rail separately. Consequently, the cost is reduced and stable performance is displayed with less trouble based upon belt properties and adjustment variance among respective scanning devices.

Title: Skew structure for linear pulse motor
Inventor: FUKUYAMA NORIO
IPC: H02K41/03
Filed: 1985-11-27
Abstract: PURPOSE:To move at a constant sped at high speed time by skewing scale teeth or poles within one pitch of the scale teeth. CONSTITUTION:Scale teeth 21a of a scale 21 are formed obliquely to a linear line L perpendicularly crossing both sides of the scale 21, i.e., or are skewed. In this case, the skew is achieved with in range smaller than one pitch P of the teeth 21. When the teeth 21a and the poles of a slider are opposed, they are opposed in an obliquely crossed manner. Accordingly, a variation in the intensity of a magnetic field formed between both becomes gentle not to generate a speed ripple at high speed time, thereby obtaining moving characteristic near a constant speed.

Title: Telephone exchange
Inventor: OUCHI MASATOMO
IPC: H04N7/14
Filed: 1989-10-12
Abstract: PURPOSE:To display an internal data in an easy to see form simply by the operator by displaying the internal data of a telephone exchange onto a television telephone set. CONSTITUTION:When a controller 103 detects dialing and recognizes it that a received dial signal is a special number '8' for output to a still picture television telephone set, the controller 103 checks whether or not a caller terminal equipment is a still picture television telephone set. When the caller terminal equipment is not the still picture television telephone set, the controller 103 discriminates the signal resulting from an operation error and sends a tone representing an error or the like to the terminal equipment, and when the caller terminal equipment is the still picture television telephone set, the controller receives 2nd and 3rd dial digit signals to bring the state into the talking state. When the 2nd and 3rd dial digit numbers are '0'b, '0' for charging information in this state, a data relating to the charging information is extracted from a rewritable memory 106 and a data converter 109 converts the data into picture information. Then a channel switch is controlled so as to send the picture information formed by the data converter 109 to the still picture television telephone set 114. Thus, the internal data is displayed in an excellent way.

Abstract: PURPOSE:To correct the phase difference between respective optical beams with a simple constitution by reading image information corresponding to the plural optical beams by a picture scanning clock corresponding to the optical beams of the plural optical beams photodetected by an optical sensor initially. CONSTITUTION:When a synchronizing sensor FS photodetects the optical beam from a laser diode LD1 of a semiconductor laser array LD, a phase locked loop circuit PS outputs a clock signal CK0 according to this output, inputs to a column management address counter CA and a control circuit CC and the image information of the designated address is read from a memory ME and latched to a latch circuit LC. A delay circuit TC produces the image scanning clocks signals CK1-CKm corresponding to the respective laser diodes LD1-LDm of the semiconductor laser array LD and outputs, they are inputted to respective shift registers SL1-SLm as shift clocks and the respective image information is outputted successively. Since there is the phase difference of a delay time according to the phase shift in a main scanning direction in the signals CK1-CKm, the phase difference between the respective beams is corrected.

Title: Electrolytic solution for electrolytic capacitor
Inventor: KIKUCHI TSUYOSHI
IPC: H01G9/035
Filed: 1990-10-06
Abstract: PURPOSE:To improve a withstanding voltage without affecting other characteristics adversely by adding titanium dioxide in electrolytic solution using ethylene glycol as dispersion solvent. CONSTITUTION:Titanium dioxide is added to electrolytic solution using ethylene glycol as dispersion solvent. This colloid is TiO2 hydrate TiO2.xH2O (x=1 to 10) having a size of 5 to 50mum and polymer particles thereof exist with cations as stabilizer in electrolytic solution. If such electrolytic solution is introduced into an element, an insulating layer of TiO2 is readily formed on an aluminum oxide surface since TiO2 itself is negatively charged. The insulating layer effectively functions to improve a withstanding voltage of a capacitor; however, it does not affect adversely other characteristics such as capacity and tan delta.

Title: Electrolyte for driving electrolytic capacitor
Inventor: YAMADA YUTAKA
IPC: H01G9/035
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To improve the characteristics and reliability of an electrolytic capacitor at a low cost by adding triethyltetramine hexa-acetic acid to an electrolyte prepared by mixing ethylene glycol with water and dissolving at least either adipic acid or benzoic acid in the solution. SOLUTION: An electrolyte for driving electrolytic capacitor is obtained by adding 0.01-3.0wt.% triethyltetramine hexa-acetic acid to a solution prepared by dissolving at least one kind of organic carboxylic acid composed of adipic acid or benzoic acid or the salt of the acid as a solute in a solvent prepared by mixing ethylene glycol with 10-30wt.% water. Consequently, the occurrence of a gas is suppressed, because the hydration between the water contained in the electrolyte and electrode foil at a high temperature is suppressed even when the adding amount of the water increases. Therefore, an electrolyte which has an excellent electrical conductivity and is stable at a high temperature can be obtained.
