Patent JP-H1110571-A (JP)
Title: Nozzle unit of electronic part packaging device
Inventor: TANAKA SATOSHI
IPC: H05K13/04
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To surely inhibit leak of air to strongly vacuum suck a large-sized electronic part to be held by making a space formed by the lower end part of a nozzle, the upper surface of an electronic part and the inner surface of a suction pad air-tight. SOLUTION: An electronic part 3a is vacuum sucked by the lower end part of a nozzle 18, and the lower end part of a suction pad 23 is brought into contact with the upper surface of the electronic part 3a to be subjected to upward force F1. Accordingly, the lower end part of the suction pad 23 is bent to be turned upward, and is brought into close contact with the lower surface of a fitting part by its reaction force F2. Accordingly, the space formed by the lower end part of the nozzle 18, the upper surface of an electronic part 3a and the inner surface of the suction pad 23 becomes an air-tight space 20 without leakage of air, thereby vacuum sucking the electronic part 3a strongly to be held. As the material quality of the suction pad 23 is deteriorated due to a long time use, replacement is conducted.  In this case, the suction pad 23 is drawn out from.the nozzle 18, and a new suction pad 23 is simply installed in the nozzle 18.

Title: Cold cathode discharge tube
Inventor: MORI YUSUKE
IPC: H01J61/067
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a cold cathode discharge tube in which lighting start voltage and lighting keeping voltage can be reduced, and the efficiency of electric-light transformation is enhanced by providing a minute clearance having a width substantially equal to or smaller than the average free stroke of discharge gas on at least one of electrode parts situated within a glass bulb. SOLUTION: A minute clearance formed between a first electrode 1 and a second electrode 2 has a width smaller than or substantially equal to the average free stroke of the discharge gas sealed in a discharge tube. The ionized or excited molecule of the sealed gas reaches the electrode surfaces without colliding other gas molecules in the moving stroke by electric field and heat, and collides it. Thus, the above moving gas molecule consumes all energy for the collision with the electrodes without loosing it by the collision with other gas molecules, so that an emitting mechanism of secondary electron can keep the maximum efficiency. Since the movement of the sealed gas ion never loose the charge by the collision, emission and acceleration of primary electrons from the electrode surface can be promoted.

Title: Method and device for humidifying
Inventor: PETER GOLUCHI
IPC: F24F6/18
Filed: 1996-06-08
Abstract: PROBLEM TO BE SOLVED: To effectively prevent steam from being condensated to form water droplets by supplying the steam, from which the water droplets are removed, to a steam pipe and heating the steam by a heating pipe in the steam pipe and spraying the steam to air conditioned air from a steam spray nozzle to humidify the air conditioned air to a prescribed humidity. SOLUTION: In a separator 1 connected to a steam source, steam jetted from a steam outlet port flows in a spiral current along the lower surface of a spiral plate 8, descends along the inner surface of a main body 7, and collides with a baffle plate 12 on the bottom part therein. Thus, water droplets are separated and the spiral current moving upward in a thin spiral current is formed owing to a protruding part at the center of the baffle plate 12. Then, a part of steam passes through a connecting pipe connected to the side surface of the main body 7 is discharged to a steam pipe 2, sprayed from steam spray nozzles 4 and mixed with air-conditioned air. The rest of the steam is supplied to a heating pipe 5 in the steam pipe 2 through a connecting pipe 15 connected, to the upper surface of the main body 7, heats the steam in the steam pipe 2 and then exhausted.

IPC: B25H7/04
Filed: 1992-06-03
Abstract: PURPOSE:To enable simple marking with a high accuracy by radiating laser beams to the face to be marked by horizontal rotation, and applying material, colored or discolored by laser beams, to the face to be marked. CONSTITUTION:In the case of performing marking to the column wall surface 4 of a building, a rotary laser level 1 is set into the height position of 1000mm, for instance, from the floor of a slab 2 first, and UV group laser beams 3 are continuously radiated to the column wall surface 4 by horizontal rotation. Coating material intermixed with material colored or discolored by laser beams such as photochromic material or thermochromic material is then applied by spraying on the laser beam radiated face using a spray gun 5. The laser beam applied part is thereby colored/discolored to blue from colorless or to violet from pink, for instance, so as to reveal a level marked line 6.

Title: Key input device
Inventor: SATOU TAKASHI
IPC: H03M11/02
Filed: 1980-11-29
Abstract: PURPOSE:To make input faster and sure, by making key discrimination through the coincidence between the keys depressed at the first time and the second time, on a keyboard having a rollover function. CONSTITUTION:When the 2nd key is depressed while the 1st key is depressed, if the 2nd key is depressed succeedingly after the 1st key is detached, since the key-off signal is at ''1'' level, a flip-flop 17 is in a set state. Thus, the key line data and encoding data obtained from the 1st key are stored in storage registers 12, 14. Next, the storage by the 2nd key is started. As to the key line data and encoding data inputted from the 2nd key, the comparison with the data in the storage registers 12, 14 is made at coincidence circuits 15, 16. If the coincidence at both the circuits is not taken, the input from the 2nd key is set to key buffers 7, 9.

Title: Improving method of humidity resistance for resin sealed semiconductor device
Inventor: YOSHIDA TOORU
IPC: H01L23/522
Filed: 1981-10-23
Abstract: PURPOSE:To improve the humidity resistance of a molded element by providing an Al2O3 protective film on an exposed Al wiring in a minute clearance between a resin and a semiconductor chip by firing the molded element at a high temperature. CONSTITUTION:A molded element is treated in an atmosphere inchuding O2, and having a temperature not exceeding the maximum rated storing temperature (e.g. 120 deg.C) immediately before the final inspection or immediately before use, the temperature being different depending on the kind of the resin used. Thus, O2 enters the clearances between the resin and a lead frame, and between a lead wire and a chip, and an Al2O3 film is formed on an exposed Al, by which the reliability in humidity resistance is improved.

Title: Smoke discharging device
Inventor: ISHIHARA TAKAYUKI
IPC: B01D45/08
Filed: 1983-09-13
Abstract: PURPOSE:To make cleaning effect of cleaning liquid supplied from a cleaning liquid nozzle for the surface of baffle plates uniform, to reduce the number of nozzle miniaturizing also a pump, thus to reinforce the baffle plates by bending top ends of the baffle plates provided to the inside wall of a smoke discharging device toward suction side of soot. CONSTITUTION:Soot generated during cooking is sucked by a fan into a smoke discharging device. The stream of soot is forcibly deflected by baffle plates 18 provided to the inside wall 19, and oily matters in the soot are allowed to collide against the surface of the suction side for the soot of the baffle plates 18 and against the surface of the inside wall 19 by the inertia force to cause deposition. Thus, the soot is removed. Cleaning liquid in a storage tank 17 is ejected by a pump 23 from nozzles 20, 21. The cleaning liquid ejected from a nozzle 21 for cleaning the baffle plate collides against the baffle plates 18 and a part of the liquid spreads along the bent part 24 at the top ends of the baffle plates and flows down on the surface of the suction side for the soot. Thus, the cleaning liquid is not scattered from the top ends of the plates and the cleaning area to be treated by one nozzle is increased.
