Title: Scribing method for semiconductor wafer
Inventor: TATEISHI YASUO
IPC: H01L21/301
Filed: 1984-05-30
Abstract: PURPOSE:To suppress the generation of chippings without making the width of a scribe line wider by a method wherein, after a narrow-stripped insulating film having the width narrower than that of the scribe line is formed in the center part, the narrow- stripped insulating film is scribed using a cutter. CONSTITUTION:After a thermally formed oxide film 2 is selectively formed on the main surface of a silicon substrate 1, the first resion 3 of the conductive type reverse to that of the substrate 1 is formed, and then the second region 4 of the conductive type reverse to that of the first region is formed. When windows 3a and 4a are formed, a part of the oxide film located on an expected scribe line 5 is removed simultaneously. To be more precise, a narrow-stripped oxide film 6 having the width W2 which is narrower than the width W1 of the expected scribe line is left approximately in the center part of the scribe line 5. Then a PSG film 8, for example, is coated on an aluminum electrode layer 7 as a passivation film, and the PSG film on a bonding pad 9 is removed. When the narrow-stripped oxide film 6 is going to be cut by a diamond blad 10, if the rolling of the blade 10 is small, the width W2 of the narrow-stripped oxide film becomes narrower, and as a consequence, the width W1 of the scribe line can be designed smaller, thereby enabling to prevent the generation of chippings and cracks on the edge 6a.

Abstract: PURPOSE:To enable the number of discharge ports to be freely changed by simply changing a distributor, by a method wherein a plurality of discharge ports of a distributor are sequentially and selectively opened in synchronism with the discharging period of an oil pump. CONSTITUTION:When driving shafts 14, 16 are driven by a crankshaft, a worm wheel 26 of the oil pump 10 is rotated by one revolution to discharge a lubricating oil once, during which a worm wheel 78 of the distributor 12 is rotated, for exampel, by 1/6 of a revolution.

Title: Magnetic head driving actuator
Inventor: SATO YOSHIHIRO
IPC: H02K33/18
Filed: 1980-08-09
Abstract: PURPOSE:To increase the positioning accuracy of a magnetic head, by attaching a ferromagnetic material bar on a bobbin and thus suppressing the vibration of a carriage system. CONSTITUTION:A plural number of ferromagnric material bars 30 are attached equidistantly around the main body of a bobbin 5. Thus the magnetic force of a single direction is applied to each bar 30 to attract the bar 30 toward three magnets provided around the magnetic field in the gap of a voice coil motor magnetic circuit or toward a center yoke 2. This is equivalent to the fact that a reinforcing member is provided around the main body of the bobbin 5 to stretch the bobbin toward the outer or inner side. As a result, the circular vibration toward the radius of the bobbin 5 is suppressed significantly.

Title: Maintenance guide system
Inventor: IKEGAMI HARUHIKO
IPC: G05B23/02
Filed: 1994-05-24
Abstract: PURPOSE:To provide the maintenance guide system for shortening the time of recovery from device abnormality. CONSTITUTION:A maintenance guide system 1 uses a main body 2 of a personal computer provided with an abnormality factor deciding part 21 and a storage device 22 in comparison with the conventional example. Concerning the display order of abnormality factors at the guide system 1, first of all, a display order deciding value is calculated by an expression and the order of abnormality factors to be displayed on a display device 7 is decided from the larger values. When the display order deciding value is equal, the display order of abnormality factor with the larger number of deciding conditions is decided higher. Therefore, since the display order shows the high possibility of abnormality generation, the abnormal parts can be efficiently recovered and the time required for recovery can be shortened.

Title: Displacement measuring device by ultrasonic wave
Inventor: TANAKA HIROAKI
IPC: G01S15/10
Filed: 1982-06-26
Abstract: PURPOSE:To measure displacement accurately, by employing a pulse radar system and a phase difference system in combination, and emitting an ultrasonic wave after pulse modulation. CONSTITUTION:A signal detector SD is fixed to an axle by a stay 4 and a bolt 5. Then, a transmitter TRM and a receiver RCV are fixed in the signal detector SD at right angles to the ground surface 1. When the distance between the transmitter TRM and receiver RCV, and ground surface 1 increases or decreases by lambda/2, signals of Q4-Q8 or Q4-Q1 of a twisted ring counter 119 appear at the output terminal of a multiplexer 118 in sequence. The signals appear on a signal line 400 and are transmitted to a computing device CMP. The CMP measures the time (t) of the signals and averages the time by as many times as specified to obtain the distance between the axle and road surface. Thus, the displacement is detected regardless of variation in received sound pressure to take the accurate displacement measurement.

Abstract: PURPOSE:To prevent any unstableness of the revolution of an engine by constructing the unit in the caption in which fuel injections are performed for all cylinders at the same time when all data of cylinders become values which are not in a predetermined order, later, fuel injection is prohibited until a specific cylinder is detected.

Title: Combined sintered parts and its manufacture
Inventor: AKECHI KIYOAKI
IPC: B23K26/32
Filed: 1995-05-08
Abstract: PURPOSE: To obtain the equal joint strength as a base material without welding defects by controlling under specific values the amount of oxygen, impurities like stains and groove clearance of a sintered material to be laser-welded. CONSTITUTION: In the case of manufacturing combined sintered parts by joining iron-based sintered parts 2 and steel parts 3 by a laser welding method, the oxygen content of the iron-based sintered parts 2 is made 0.2wt% or less. In addition, the impurities are made 0.3wt% or less for the surface stains or the like of a place 1 to be welded, the groove clearance being 0.2mm or less in the weld zone with the steel parts 3 of the opposite material, before the laser welding is performed. In order to secure dimensional precision required after welding, machining before welding is sometimes necessary since machining after welding is impossible.  Upon examining the influence of various pre-welding treatments after machining on the normal/defective condition of a weld joint, the dry method proves to be desirable, even if machining is performed, in the case of a sintered material which is easy to be oxidized and stained and which is also difficult to be completely cleaned.

IPC: C08J9/18
Filed: 1989-04-28
Abstract: PURPOSE:To obtain expandable thermoplastic polymer particles which can give uniform and fine cells by adding an amide compound as a nucleator at a specified time in a polymerization process in the production of said particles by a seed polymerization process. CONSTITUTION:Thermoplastic polymer particles of a uniform particle diameter (e.g. polystyrene particle) as seed particles are suspended in water. A polymerizable monomer (e.g. styrene) is continuously or intermittently added to the aqueous suspension. During the polymerization, an amide compound (e.g. ethylenebisstearamide) is added to the system before the amount of the added polymerizable monomer exceeds one half of the total amount of addition. By impregnating the polymer particles after adding the amide compound and the polymerizable monomer with an easily volatile blowing agent (e.g. butane), expandable thermoplastic polymer particles having uniform particle diameters and being capable of forming uniform and fine cells when expanded can be obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent a coated optical fiber from having curling even if this fiber is rounded and is housed into a closure section and to substantially prevent the occurrence of instantaneous loss of transmitted light by forming a coating layer consisting of a UV curing resin having a specific equil. modulus of elasticity on an optical fiber. SOLUTION: The coating layer 3 of the coated optical fiber 1 is composed of the UV curing resin having the equil. modulus of elasticity of <=6×10<7> Pa. The equil. modulus of elasticity signifies the modulus of elasticity in storage which is made constant at a temp. above a glass transition temp. in measurement of a dynamic modulus of elasticity. When the coating layer 3 is formed on the optical fiber 1 by using the UV curing resin having the equil. modulus of elasticity below 6×10<7> Pa, more preferably below 5×10<7> Pa, the coated optical fiber 1 hardly curls. The examples of the UV curing resin include an urethane acrylate system, epoxy acrylate system, etc. A quartz glass based glass fiber is used as the optical fiber 2.
