Title: Gas laser tube device
Inventor: MATSUDA MASAYASU
IPC: H01S3/041
Filed: 1986-11-21
Abstract: PURPOSE:To inhibit the fine change of direction of laser beams by forming a through-hole to one part of the air flow side lower than a discharge capillary section for a radiator plate fixed onto the outer circumference of the discharge capillary in a heat transfer manner. CONSTITUTION:Holes 33 for fitting a discharge capillary are shaped to sections nearer to the upstream side of the flow of cooling air than the center in each radiator plate 31 fastened onto the outer circumference of the discharge capillary section in a heat transfer manner. Through-holes 34 are each formed where corresponding to size L3 smaller than size L2 from the holes 33 for fitting the discharge capillary on the flow side lower than the holes 33 for fitting the discharge capillary. Accordingly, the generation of the turbulent flow of cooling air on the downflow side of the radiator plates is inhibited, and the natural vibration frequency of radiator therm-selves is displaced, thus effectively suppressing the oscillation-start initial stage of laser beams and the fine change of direction.

Title: Electrochemical measurement apparatus and method for solution
Inventor: OGINO HARUO
IPC: G01N27/401
Filed: 1990-10-17
Abstract: PURPOSE:To enable measurement with stability for a long term by using in liquid route piping, which includes a solution absorbing retaining material inside and forming a structure to make electrolyte solution in the piping flow in one direction. CONSTITUTION:In a piping 7 made of a material which is anti-erosion to a solution 2 to be measured and electrolyte, a material consisting of stranded filaments made of the same anti-erosion material is inserted as a solution retaining material.

Title: Die bonding of semiconductor chip
Inventor: HATANO KAZUFUMI
IPC: H01L21/683
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To peel a semiconductor chip off an expanded tape and die-bond it on a bonded body and position it easily by expanding and heating the expanded tape which has a foam sheet adhered to it and has a pressure sensitive adhesive formed on the surface of the foam sheet. SOLUTION: An expanded tape 8 consists of a main body of a tape 8a, a thermal foam sheet 8b which is sticked at its rear face to the main body of a tape 8a, and a pressure sensitive adhisive 8c which is adhered to the surface of the thermal foam sheet 8b. With the expanded tape 8 being expanded and an expanding ring being fastened to the tape 8, a heater block is heated to such a temperature which is higher than the one at which the foam sheet 8b generates foams. By this, a semiconductor chip is pushed upward against the main body of a tape and is partially peeled off from the expanded tape 8. Nextly, the whole body of the semiconductor chip is peeled off from the expanded tape 8 by suction and is moved toward a specified place of a bonded body and then is bonded.

Title: Digital black clamp
Inventor: SUTEIIBUN EE BARON
IPC: H04N5/361
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To quickly obtain the black level value at which picture signals can be corrected by accumulating and averaging digitized black level picture element signals. SOLUTION: A CCD picture element sensor 10 having masked black picture elements forms the picture of a scene passing through a lens 12 and generates video signals. The video signals are processed by means of a correlator circuit 14 and correlated picture signals are generated. A picture signal channel converts analog video signals into digital video signals by means of an A/D converter 20 through a gain stage 18. Since black-level picture signals digitized by means of the converter 20 are accumulated and averaged by means of a digital accumulating and averaging circuit 22, an accurate black-level value is obtained quickly and the picture signals are corrected by feeding back the black-level value to a loop.

Title: Method of and apparatus for cleaning printing screen
Inventor: TANI OKIE
IPC: B41F35/00
Filed: 1994-10-04
Abstract: PURPOSE: To smoothly remove unnecessary residue on a back surface of a screen to constantly improve efficiency by providing renewal of the screen each time a shaft rotates an angle corresponding to a feed pitch of a feed roller at a time, and pushing a renewed surface against the back surface of the screen through a tip end of a blade for cleaning. CONSTITUTION: When an air cylinder 6 descends, a unit U is lowered through a support plate 7 and a transmission rod 8, and a blade 4 having contacted with a screen S and a cloth screen P covering a tip end of the blade accordingly separate from the screen S. Until completion of downward action to a predetermined position, a drive lever 10 acts through a connection rod 9 to rotate a feed roller a predetermined pitch through a one-way clutch 11. In this process, a primary surface of the cloth screen P having covered a cleaning blade is renewed. In a subsequent ascending action, a shaft is made stationary and hence the cloth screen P is not moved due to a mechanism of the one-way clutch 11, thereby serving as a renewed surface to contribute to removal of residue on the screen S.

Title: Infusion catheter
Inventor: MATSUDA TAKEHISA
IPC: A61F2/958
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to subject only the lesion to an expansion treatment and to administrate a medicine of a relatively high concn. to the lesion in succession thereto. SOLUTION: The infusion catheter 1 has an expanding/contracting balloon 5, an infusion port 23 for releasing the medicine into the blood vessel and a blood flow passage for allowing the blood flowing in from a side hole 29 to flow out of a front end opening 25. At the time of expanding the lesion 51, the blood vessel is closed by the balloon 5, but the blood flows into the side hole 29 and flows out of the front end opening 25 and, therefore, the blood flow is maintained. The medicine stagnates in the blood vessel between the infusion port 23 and the front end opening 25 when the medicine is released from the infusion port 23 by moving the position of the balloon 5 after the completion of the expansion treatment. Then, the lesion 51 is administered with the medicine of the relatively high concn. while the blood flow is maintained.

IPC: B63B7/08
Filed: 1993-11-09
Abstract: PURPOSE:To provide stability and eliminate influence on human life by forming an inflatable canoe comprising multiple air chambers with four or more of air chambers. CONSTITUTION:In an inflatable canoe comprising four air chambers, a bottom air chamber is composed of two layers of a bottom outer air chamber 2a and a bottom inner air chamber 2b. Also the air chambers inside and outside a side upper air chamber 1e and a side lower air chamber 1f and an air chamber 1d can be formed detachably and insertably. Then they are stuck fixedly to desired parts of an outer layer air chamber and an inner layer air chamber with a magic tape or belt cloth on the rear surface of which adhesive agent is applied, and a canoeist selects them detachably as required and inserts for use. Because the number of air chambers is increased, even if one air chamber is broken, two air chambers at each part will bring the canoeist into shore by rowing. Thus a canoe is large in turnover angle, will not turn over, stable, and small in turning radius.
