Title: Package with tear tape
Inventor: KIYOSHIMA AKITATSU
IPC: B65D77/30
Filed: 1990-04-04
Abstract: PURPOSE:To obtain a sufficiently long tear part to unpack a package without using any perforation by a method wherein a film is slit to form a tab piece at a tear starting point and the one end of a pressure-sensitive adhesive tape is positioned at the foward side of the tab piece, extended throughout the tear line over the tab piece and attached to the outer peripheral side of the film. CONSTITUTION:Film 1 is provided with a V-shaped slit 2 at a tear starting point of a package to form a tab piece 3. A pressure-sensitive adhesive tape 4 is applied to the film with the one end thereof positioned at the forward side of the tab piece 3 and extending to cover the tab piece 3. This end of the pressure-sensitive adhesive tape 4 is folded back on its adhesive side to form a grip part 6. When the package is unpacked by tearing off the pressure- sensitive adhesive tape 4, this grip part 6 affords a hold for the fingers to pull the tape 4 and, therefore, makes the tearing easy.

Filed: 1987-04-09
Abstract: PURPOSE:To mount a package in a short time by forming a plurality of the leads, noses of which are bent, to the surface mounting component package, bringing the leads into contact into through-holes by the elastic force of bent sections in the leads and removing soldering. CONSTITUTION:A surface mounting-part package has a plurality of leads 3, noses of which are bent. The leads 3 are bent in through-holes 5 when a printed substrate 4 is mounted, and brought into contact into the through-holes 5 electrically at all times by the elastic force of the bent sections. Accordingly, soldering is removed, thus mounting the package in a short time.

Title: Inspection of tile unit
Inventor: MORITA MASAKATSU
IPC: E04F13/08
Filed: 1991-04-19
Abstract: PURPOSE:To automatically inspect the quality of a tile unit. CONSTITUTION:The whole image of a tile unit 1 is taken to accurately specify the positions of the edges of respective tiles 2. Inspection regions J1-J23 are set to the corner parts of the respective tiles so as to straddle joints and scanned in a joint traversing direction. When the joint is detected even at one place within a certain inspection region, it is judged that the tiles 2 are not in a mutual contact state in the inspection region. By this method, it can be certainly judged whether there is the mutual contact or overlap of the tiles in the tile unit 1.

Title: Apparatus and method for radiant type air conditioning
Inventor: SAWADA IKUO
IPC: F24F1/00
Filed: 1995-03-23
Abstract: PURPOSE: To provide a radiant type air conditioner featured by a simple structure, low construction and material costs and a reduced construction period, from which a stable air conditioning effect can be obtained. CONSTITUTION: A recess formed in a bottom face of a one-way concrete ceiling slab 1 is closed to form a slab duct 3, into which air-conditioned air is made to flow to cool a room-side face of the concrete ceiling slab 1.

Title: Isdn basic access terminal equipment
Inventor: IWASAKI SUSUMU
IPC: H04L69/14
Filed: 1989-04-06
Abstract: PURPOSE:To build up a high speed communication network able to send many pcs. of information by using 2 B-channels so as to send/receive a signal 128Kb/s. CONSTITUTION:Channels B1 and B2 of two independent signals 64Kb/s are connected to a terminal equipment of a destination via an ISDN to eliminate the time difference between both the B-channels and the relative arrangement is made coincident between both the transmission reception terminal equipments. When the setting of swap switches 6, 10 and a delay buffer 5 is finished, the transmission terminal equipment restores inserters 3, 4 to apply multiplex and demultiplex to an input signal 128Kb/s into a signal on the channels B1 and B2 by a DMUX 1 and the resulting signal is transferred to the reception terminal equipment via the ISDN. The reception terminal equipment uses a MUX 11 to multiplex the signal 128Kb/s, which is transferred to a data terminal equipment thereby applying communication of the signal 128Kb/s. Thus, even in a narrow band ISDN using the signal 64Kb/s as a basic bearer, the high speed digital communication of using the signal 128Kb/s is attained.

Title: Resin-sealed semiconductor device
Inventor: YOSHIDA IKUO
IPC: H01L23/29
Filed: 1988-04-13
Abstract: PURPOSE:To improve reliability of a resin-sealed semiconductor device which has an increased size, fine construction and multilayer interconnections, by interposing an adhesive layer having high adhesion properties to both a peripheral substrate layer and a sealing resin between the peripheral substrate layer and the sealing resin. CONSTITUTION:The top of a silicon substrate 100 is covered with a first interlayer insulating film 102, except an electrode connecting hole 103 and the peripheral edge (substrate peripheral layer) 500 of a semiconductor chip. A metallic wiring layer 110 of aluminium alloy or the like is deposited and then a titanium nitride film 120 is deposited on the substrate peripheral layer on which the silicon substrate is exposed. A chip is mounted on a lead frame and an electrode of the chip is connected with a lead of the lead frame through a gold wire 300. The lead frame is set in molds so that the device is sealed with a sealing resin 400 principally composed of epoxy resin or the like. The titanium nitride film 120 presents extremely high adhesion to the silicon substrate 100 as well as to the sealing resin 400. Accordingly, in the peripheral edge region of the semiconductor chip, the chip can be adhered with the sealing resin with improved adhesion strength. Thus, the sealing resin can be prevented from being broken or peeled by a thermal shock test.

Title: Pole change type rotary electric machine
Inventor: MOCHIZUKI SUKEYASU
IPC: H02K17/14
Filed: 1985-04-25
Abstract: PURPOSE:To simplify a terminal switching unit by alternately providing N pieces and (N+1) pieces of conductors of two sets of coils contained in slots circumferentially, thereby reducing the number of switching terminals while employing a single winding type which enable to reduce the size. CONSTITUTION:The number of conductors of coils disposed at the downside in a slot are sequentially 2, 1, 2, 1... to be contained in the slot of large number from that of 1 contained in the slot, and the numbers of the conductors per each slot are similarly sequentially, 1, 2, 1, 2... in odd numbers. Windings A1... are connected with each other, and 6 terminals are led. Since six poles and four poles of a rotary magnetic field can be switched by suitably switching the six terminals, the terminal switching unit can be made extremely simple. Since a single winding type is used, the entire armature can be largely reduced in size.

Title: Method for recognizing division pattern of radiation image
Inventor: TAKEO HIDEYA
IPC: G06T1/00
Filed: 1989-04-07
Abstract: PURPOSE:To accurately recognize a division pattern by deciding an apex changed in upward or downward projection appearing on the profile of image data on each line segment in a direction to traverse a boundary as a boundary candidate point, and setting the line segment along the point as the boundary. CONSTITUTION:When a recording sheet is divided into plural parts and radiographing is performed at every divided part, the profile of image data on each line segment is found for each of a large number of line segments in the direction to traverse the boundary based on the image data in the neighborhood of an area where the boundary of each part exists. And the apex changed in the upward or downward projection appearing on each line segment on the profile is decided as the boundary candidate point, and furthermore, it is discriminated whether or not density at those boundary candidate points are different from another, and when the density at those boundary candidate points are remarkably higher or lower than another, a straight line is decided as the boundary. In such a way, the division pattern of the recording sheet can be accurately recognized.
