Title: Circuit board
Inventor: IWATA MASANORI
IPC: H05K3/24
Filed: 1994-12-28
Abstract: PURPOSE: To enable a circuit pattern formed even narrow in pitch to be electrically connected to external terminals through a connecting medium by a method wherein the surface of a circuit board is set lower than a specific value in center roughness. CONSTITUTION: A circuit board 1a is composed of a single crystal silicon board 11a and an alumina board 11b or the like which are smaller than 150Å in average center roughness, and electrodes 2 are patterned on the upsides of the boards 11a and 11b. A solder plating coat 3 is formed on the surfaces of the electrodes 2 for soldering the electrodes 2 to outer terminals 4. The surface of the circuit board 1a is set smaller than 150Å in average center roughness, so that the molten solder plating coat 3 is hardly attracted to the upside of the circuit board 1a, and the molten solder plating coat 3 is capable of flowing smoothly towards the outer terminals 4. Therefore, a solder fillet enough in volume is formed on the surface of the outer terminal 4.

Title: Indoor suction grille for duct interspace mount type ventilating fan
Inventor: NAGAI HIROYUKI
IPC: F24F7/10
Filed: 1990-11-30
Abstract: PURPOSE:To contrive the common use of an indoor suction grille by enabling joint work of tubes of different inner diameters by installing a spring mount section of an indoor suction grille so that its outer periphery may be deformed and combining a smaller sized side of an outer diameter of said spring mount section with a smaller sized side of a pipe whose inner diameter is different or fixing a clearance between the outside shape of the spring mount section and the inner diameter of said pipe. CONSTITUTION:An inner suction grille comprises a grille section 2 located indoors and a main body section 1 located in a pipe in the ceiling. A cylinder-shaped section 5 is installed in the central part of a flange section 3 where the cylinder-shaped section 5 whose position is point-symmetric with respect to the center, is deformed in shape. A deformed section of a spring mount section 6 installed on the cylinder-shaped part 5 is provided with an outside diameter of A and an outside diameter B having the relation of A>B. The clearance between the inner diameter phi100 of a VP pipe and its outside diameter section and the clearance between the inner diameter phi107 of a VU pipe and its B outside diameter section are arranged to be identical to g dimensions. The indoor mount grille is mounted in the VP pipe and the UV pipe by means of amount spring 7 fixed to the spring mount section 6. A reinforced rib section 8 prevents the deformation of the cylinder-shaped section due to the reaction of the mount spring 7 when the indoor suction grille is mounted in the pipe.

Title: Method for removing slag in automatic welding and device therefor
Inventor: OKAMOTO MASASHI
IPC: B23K9/32
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To remove slag without interrupting an automatic welding and to improve the working efficiency by executing the automatic welding and simultaneously, driving a slag-removal member disposed at the rear side of the advancing direction of a welding torch to remove the slag on a welded bead. SOLUTION: The automatic welding is executed with the welding torch 2 and simultaneously, the slag-removal member 8 disposed at the rear side of the advancing direction of the welding torch 2 is driven with a rotation- driving device 11 to remove the slag on the welded bead 7. Thus, when the following layer is automatically welded, in the case of again igniting the arc at the finishing point position, the current flow is not obstructed with the slag, but the arc is surely generated and the automatic welding can be executed. In the case of executing the automatic welding to the following layer by returning back the welding torch 2 to the starting point, the torch holder 1 is turned at 180 deg. with the axis of the welding torch 2 as the center, and the slag-removal member 8 is disposed at the rear side of the advancing direction of the welding torch 2.  The slag is automatically removed and the working efficiency is improved.

Title: Process for accelerating lift-off of photoresist patterned on substrate and thin-film device
Inventor: JENNISON MICHAEL J
IPC: G11B5/39
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a photoresist lift-off profile recessed inward for the purpose of the thin-film device processing of a special application. SOLUTION: The photoresist 70 is patterned in the conventional form on a thin-film layer existing on a suitable substrate 62 and is then exposed to a suitable developer, in consequence of which photoresist regions 70 having substantially perpendicular side walls are obtd. An electron beam or other suitable energy source is thereafter used to accelerate the electrons of a sufficient dosing quantity down to the sufficiently controlled depth in the photoresist, by which the upper parts of the images of the positive type resist are crosslinked (or made relatively insoluble). The second electron beam is thereafter distributed over the entire part of the thickness of the photoresist, by which the lower parts of the photoresist are made relatively soluble in the developer.  The resist is thereafter developed for the predetermined time, by which undercuts 78 are formed in the lower parts of the photoresist 76.

Title: Remote control transmitter
Inventor: DAGURASU MAABIN KIINAN
IPC: H04Q9/14
Filed: 1989-12-21
Abstract: PURPOSE: To efficiently compress data used by the memory of an infrared remote controller by generating a remote control signal in a selected form in response to encoded data stored in a memory means. CONSTITUTION: A set of compressed data consists of a format structure FS and a compressed function table CFT. A controller 400 receives a clock signal from a clock oscillator 410 and addresses a memory 420 in accordance with programmed instructions. The memory 420 includes a general area 422, an area 424 for storage of FS data, and an area 426 for storage of CFT data. In the learning mode, the controller 400 stores 'raw' data in the general memory 422 and extracts data indicating a format structure to store it in the FS memory 424 and compresses data related to a command and stores it in the CFT memory 426 as compressed function data. Thus, the memory efficiency is considerably improved during data compression.

Filed: 1988-12-26
Abstract: PURPOSE:To prevent troubles from mis-detection by a sheet detecting means by generating a no-paper signal when continuous sheet is not in a storing means and thereafter prohibiting generating a paper signal until setting of continuous sheet is detected. CONSTITUTION:When roll paper 1 left is so little that a core is lifted up at the time of carrying start, a control circuit keeps a no-paper signal generated even after the core is placed down and a switch 10 is turned on again once the switch 10 is turned off. Then the replacement of the roll paper is confirmed by detecting the opening and closing of a door 9 through a door switch 11 and then the output of the switch 10 is also judged. When the core is lifted up together with the rear edge of the roll paper 1, too, a condition of generating a no-paper signal is kept until the opening or closing of the door 9 is carried out even if the core goes down and the switch 10 returns to an on condition.

Title: Monitoring controller
Inventor: OZAKI ETSUKO
IPC: H04W88/08
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a monitoring controller which never causes a system down when a monitoring control panel has its on fault. SOLUTION: If a bus interface panel BINT15-1 has a fault, a message signal is sent to a central control panel CP11-1. When the fault is recognized, the panel CP11-1 switches the control of a front panel to a bus interface panel BINT15-2. The panel BINT15-2 uses the slot state information on every shelf stored in a standby area instead of the data stored in a RAM and carries on the monitoring and control of a system. The panel BINT15-1 serves as a standby panel. At the same time, the addresses of the standby area and the RAM area are dynamically switched to each other. A local memory 15a-1 of the panel BINT15-1 and a local memory 15a-2 of the panel BINT15-2 share a memory area which stores the state information data.
