Abstract: PURPOSE:To form a bump by a screen printing method, to ensure the electrical connection between the bump and a bonding pad and to obtain their necessary and sufficient mechanical bonding strength. CONSTITUTION:A bonding pad 12 is formed on the surface of a semiconductor chip 11. A passivation film 13 is formed on nearly the whole of the surface of the semiconductor chip excluding the formation region of the bonding pad and in a partial region on the bonding pad. In addition, a metal bump 14 by a thick-film paste is formed directly, or via a metal film, on the bonding pad. Thereby, the bump 14 is constituted in such a way that it is bonded to the surface of the bonding pad 12 and that it is bonded to the passivation film 13 on the bonding pad.

Title: Fuel injection device
Inventor: KAKEGAWA TOSHIAKI
IPC: F02M59/44
Filed: 1984-05-30
Abstract: PURPOSE:To prevent a lubrication effect inside an injector from dropping even in time of feeding blended fuel, by interconnecting a fuel tank to the injector through a fuel pipe, while making this fuel oil so as to be led into a sliding part inside the injector. CONSTITUTION:In case of engine low load, since fuel is led into a slide spacd 19 inside an injector from a fuel pipe 18 by means of pumping action of a plunger 14 or the like, the plunger 14 or the like smoothly operates owing to lubricating action of this fuel oil itself. In case of the engine low load, water passes through an interconnecting passage 21, entering the inside of a mixing chamber 4, and it is mixed with fuel oil, thus being led into the injector 6. In this blended fuel, containing moisture though, pure fuel alone is led into the inside the slide space 19 by the fuel pipe 18 so that slide motion in the plunger or the like is smoothly performed without any problem involving this matter.

Title: Timepiece
Inventor: MOGI MASATOSHI
IPC: G04B13/00
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To maintain life time, and at the same time to thin a timepiece by supporting the barrel arbor of movement barrel for accommodating a spring by a main plate in a cantilever form. SOLUTION: A movement barrel 1 of an electronic-control-type mechanical timepiece consists of a spring 1a, a barrel gear 1b, a barrel arbor 1c, and a barrel cover 1d. For the spring 1a, external and internal ends are fixed to the barrel gear 1b and the barrel arbor 1c, respectively, the cylindrical barrel arbor 1c is inserted into a support member 2, and the barrel arbor 1c is supported by a bottom board via the support member 2 in a cantilever form, thus supporting the movement barrel 1 only by the main plate 3 via the support member 2, eliminating the need for allowing a train wheel bridge 14 to oppose the movement barrel 1, and preventing interference with the movement barrel 1 by, for example, opening a part corresponding to the movement barrel 1. As a result, the train wheel bridge 14 is arranged near the main plate 3 and the clock can be thinned.  Also, when the timepiece is thinned, the thickness of the movement barrel 1, namely, the width of the spring 1a, is not reduced, thus maintaining life time.

Title: Motor-driven camera
Inventor: MATSUDA MUTSUHIDE
IPC: G03B15/05
Filed: 1978-09-08
Abstract: PURPOSE: To elongate the service life of battery, by preventing simultaneous consumption of larger current from the battery when winding up the film by stopping power supply to the flash lighting device by means of a switch being coupled with shutter operation.  
     CONSTITUTION: When a release button is depressed, switches 54, 55 are opened, while a switch S 1  is closed, so that power supply to a motor Mo is stopped. A strobe power source circuit has always an open circuit for power supply because the switches 51, 53 are open. When the release button is set free, the switch S 1  is opened and power supply to a shutter circuit is stopped, while the switches 54, 55 are closed to feed power to the motor Mo, so that film feeding is started. When winding-up is complete, the switches 51, 52 are closed, and power supply to the strobe circuit is commenced. Therefore, large current is not always consumed from the battery simultaneously. Thus, keeping the consumption of the battery to a minimum, the camera can be used for a long period of time.

IPC: H01L29/778
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To satisfactorily bring an electrode into ohmic-contact with p-type AlGaAs with a low resistance by forming a metallic layer composed of a p-type dopant metal or its alloy on the surface of the AlGaAs and heating treating the metallic layer. SOLUTION: A metallic layer 21 composed of a p-type dopant metal or its alloy is formed on the surface of a p-type AlGaAs, namely, a gate region 8 and the layer 21 is heat-treated. The metallic layer 21 of the p-type dopant metal or its alloy is constituted of Zn or such an alloy as TiZn, etc., containing Zn. The heat treatment may be performed in any process after the metallic layer 21 is formed. Consequently, a layer containing the dopant at a high concentration is formed on the surface of the gate region 8, because the Zn from the metallic layer 21 is diffused in the p-type AlGaAs gate area 8 in the solid phase. Therefore, a gate electrode 9 is satisfactorily brought into ohmic-contact with the gate region 8 with a low resistance.

Abstract: PURPOSE:To recognize a new character string without performing the editing and registering work of an intelligence dictionary by an operator, by retrieving whether or not the character string inputted based on correction is registered in the intelligence dictionary, and updating the intelligence dictionary according to the content of a registering request by an intelligence dictionary data editing device. CONSTITUTION:The character data of a recognized result is displayed on the CRT5 of a display/correction device 4 visually. The operator confirms a displayed result by referring to intelligence dictionary data, and when it is required to correct the result, the data to be corrected is key-inputted from a keyboard 6. Whether recognized result is corrected or not is judged by the key input of the operator. Whether or not the key-inputted data is registered in the intelligence dictionary data being used until then is judged and when it is not registered, the intelligence dictionary is edited and updated by registering corrected character data inputted by the operator in the area to be registered of the intelligence dictionary. Since the updating of the intelligence dictionary is performed simultaneously with the confirmation and correction operation of a character recognition result, it is possible to recognize even the character data not being registered in a previous intelligence dictionary.
