Title: Face-down bonding method of semiconductor element
Inventor: YANAKA MAKOTO
IPC: H05K1/02
Filed: 1993-04-27
Abstract: PURPOSE:To bond a semiconductor element and a circuit board at the correct position by recognizing reference patterns with an image pickup camera, and controlling the position of a chuck part of a chip mounter so as to align the position with a through hole. CONSTITUTION:A pattern surface 10a of a semiconductor element 10 held with a flat collet 20 of a chip mounted, is brought close to a circuit board 1. A cross mark 30a and the cross mark on the chip mounter are recognized with an image pickup camera 22, respectively, from the lower side of a through hole 1a. The position of the flat collet 20 is controlled so that the positions of the cross mark 30a and the through holes 1a are aligned based on the image information obtained by processing the image of each output. Under the state wherein the position alignment is completed, the semiconductor element 10 is lowered to the side of the circuit board 1. Each bump 11 is brought into contact with each corresponding connecting terminal 5. Bonding is performed by thermocompression binding. The face-down bonding method, by which the mounting accuracy can be improved and which is suitable for the small-amount production for many kinds of articles, can be obtained.

Title: Feed roller for fixing apparatus
Inventor: EOMO KYORI
IPC: G03G15/20
Filed: 1988-04-25
Abstract: PURPOSE:To find the proper changing time of a feed roller as well as to prevent any traveling failure of a sheet from occurring by forming a groove, making a wear limit of the roller of its depth, on a circumferential surface of the feed roller for a fixing apparatus of a printer unit. CONSTITUTION:Each ring slip sine groove 5, making such a wear limit as capable of securing feed force within the specification value of its depth, is being formed at least either of a pair of first and second rollers 1, 2, constituting a feed roller, or on a circumferential surface of the roller 1 as an example in this case. Depth of each of these slip sine grooves 5 becomes shallowed in proportion as decrease of an outer diameter of the roller 1, and finally it dwindles away to nothing, but in this while, a variation in decrease of the depth of the slip sine groove 5 will correspond to a degree of the decrease of feed force due to pressure-contact between both rollers. Consequently, an operator monitors a change of the depth in this slip sine groove 5, whereby he can find a proper changing time for the feed roller.

In addition, if thickness is 4 mm or less, coupling can be sufficiently performed by one pass in TIG welding. Thus, the connected supply pipe welding the stainless steel pipe of thickness of 2-4 mm is excellent in strength and welding, and the service life is long.

Title: Vacuum concentrator using diaphragm vacuum pump
Inventor: UEDA AKIYOSHI
IPC: B01D5/00
Filed: 1995-04-03
Abstract: PURPOSE: To prevent solvent vapor from passing through a vacuum pump, being discharged to an outer frame and polluting the environment by fitting a cooling pipe and a solvent collector to the discharge port of a diaphragm vacuum pump. CONSTITUTION: In a solvent vacuum concentrator using a diaphragm vacuum pump 7, a cooling pipe 9 and a solvent collector 10 are fitted to a discharge port 9 of the pump 7. Then solvent vapor which has not been collected and has passed through the pump 7 is liquefied and completely collected by the cooling pipe 9 in the vacuum system. Thus, the solvent vapor which has passed through the vacuum pump is extremely easily and effectively prevented from being discharged to the outside to pollute experimental environment. In this way, low boiling point solvent such as diethyl ether is completely collected. Since a diaphragm vacuum pump using no lubricating oil is used, complicated maintenance work such as oil replacement is not required.

Title: Discharge lamp lighting device
Inventor: KUBOTA HIROSHI
IPC: H05B41/24
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device which is miniaturized. SOLUTION: A fluorescent lamp FL is lighted at high frequencies by inducing a high frequency voltage in the secondary winding Tr1b of an inverter transformer Tr1 by means of the parallel resonance of a resonance capacitor C2, a first inductor L1, a second inductor L2, and the primary winding Tr1a of the inverter transformer Tr1. When a surge voltage is produced in a commercial AC power supply (e), the surge voltage is applied between the collector and emitter of a transistor Q1, a voltage is generated also in the inductor L2, and a similar voltage is generated also in a detecting wiring L3. Since the voltages exceed a threshold set by a detector circuit 6, the detector circuit 6 stops operation of a base drive circuit 5 and that of an inverter circuit 2, protecting the transistor Q1 from surges.  Since the surges are detected from the detecting wiring L3, the device is miniaturized as compared with devices of the prior art.

Title: Corrosion resistant rail
IPC: C23F11/00
Filed: 1992-03-30
Abstract: PURPOSE:To provide a corrosion-resistant rail which may be used in a serious corrosive condition such as the inside of a submarine tunnel or an on-land tunnel in which water leakage is present, by laying one end part of a coating film or a covering layer on the surface of the rail at an acute angle less than a predetermined angle to the head side surface of the rail. CONSTITUTION:A coating film or a covering film 3 is formed on the entire surface of a rail 2, excepting the head top surface of the rail 2 and a part of the head side wheel contact surface thereof with which a wheel 1 makes contact. Such a process is carried out that the angle theta1 of one end part of the coating film or the covering layer 3 is set to an acute angle less than 45 deg. with respect to the head side surface of the rail 1. With the above-mentioned process, it is possible to prevent occurrence of such a fact that water is trapped at that part throughout the full length of the rail if the end part of the coating film or the covering layer 3 makes an angle theta2 around 90 deg. with respect to the head side surface of the rail 1, and accordingly corrosion is accelerated, resulting in that the coating film or the covering layer swells or comes off in an early time. Further, if the coating or covering is made over the entire surface of the rail 2 below the jaws thereof, a similar effect can be obtained even though the one end part of the coating film or the coating layer is processed so as to be set to be perpendicular to the head side surface of the rail 2.

IPC: H01L41/00
Filed: 1978-08-22
Abstract: PURPOSE: To obtain a simple-structure and small-size light source device featuring a small change on standing by mounting the piezo-element and the condenser lens at part of the package forming the semiconductor laser device.  
     CONSTITUTION: Semiconductor laser element 2 and photo detector 14 are fixed at projection part 13a of stud 13. Piezo-element 17 is formed with circular piezoelectric component 15 plus electrodes 16 and 16a. Condenser lens 4 is suppoted fixedly at step part 18a of flange 18. If the deformation mode of component 15 is to such frequency as to secure the companding vibration in the axial direction, the light spot has a displacement toward the optical axis. And in case the driving voltage is selected to feature the flexion vibration, the light spot has a displacement in the vertical direction to the optical axis and the amplitude can be controlled by the voltage. If this light source device is applied to the video disk reproduction device, the component parts of the actuator and others can be omitted to realize a simple and small-size structure. Thus a light source device featuring the simplified matching of the optical axis can be obtained and with a small change on standing.
