Patent EP-0438069-A2 (EP)
Inventor: GLIMPEL HELMUT DIPL ING
IPC: B23G5/06
Filed: 1991-01-08
Abstract: There is a tap, the threaded part 2 of which forms a cutting part 5 and a guide part 6 and is provided with an undercut 8 on a plurality of adjacent thread teeth of the cutting part 5. It is desirable if there be provided for the tap a further machining measure, by means of which advantageous compromises as regards guidance and friction can be obtained. This is achieved in that the undercut 8 of the adjacent thread teeth of the cutting part 5 changes with an increase or a decrease in its clearance angle, as seen in the longitudinal direction. As a result of the change of the undercut, the requirements regarding the prevention of miscutting and the prevention of friction-related cold welding can be satisfied and coordinated with one another in an improved manner. <IMAGE>

Abstract: In a portable type measuring instrument (10) with solar batteries, embracing as a power source a group (8) of solar batteries in which a plurality of solar batteries (12a - 12d) are series-connected on the same plane, respective light receiving windows (14a - 14d) are made to be substantially equal in area to one another, and each of the light receiving windows surrounds the outer periphery of other light receiving window adjacent thereto, whereby, even if part of an irradiating light to irradiate the light receiving windows of the solar batteries is screened by a hand (16) and other holding means for operating and holding the portable type measuring instrument, it is avoidable that only a specific light receiving window is biasedly screened, so that an electromotive current (I) of the group of the solar batteries can be efficiently produced.

Abstract: An interline transfer or frame interline transfer CCD solid image sensor is adapted to read out signal charges from light receiving sections (16) of a matrix array by means of vertical charge transfer sections (17,18) and horizontal charge transfer sections (14,15). A plurality of horizontal charge transfer sections are formed for lowering the horizontal transfer frequency. The voltage transition in the transfer gate across the horizontal charge transfer sections is caused to occur stepwise or temporally slowly to improve the transfer efficiency across the horizontal charge transfer sections. A smear drain region (28) for sweeping out unnecessary charges is formed along the horizontal charge transfer sections. The transfer electrode of the horizontal charge transfer sections connected to the busline wiring is patterned to clear contact holes provided in the smear drain region to provide for positive overflow without increasing the chip area.

Abstract: The present invention describes a unique so-called transistor/transistor logic (TTL) arrangement which uses a diode-resistor network (20, 23) to develop a stable clamping reference voltage for the open collector circuit portion of the TTL arrangement. The open collector circuit of the present invention basically uses an open collector output transistor (10) whose base is coupled through a resistor network (21, 22) to a second transistor (15) so that the second transistor (15) will go into saturation so as to direct a reference current through the diode-resistance network (20, 23) and thus prevent the open collector output transistor (10) from saturating. <IMAGE>

Each sense element includes a switching device (16), e.g. a TFT for active addressing. In a fingerprint recognition system the sensing device output is analysed and characterised data is compared with stored data for identification or verification purposes.

Abstract: A method is provided for depositing aluminum thin film layers to form improved quality contacts in a semiconductor integrated circuit device. All or some of the deposition process occurs at relatively low deposition rates at a temperature which allows improved surface migration of the deposited aluminum atoms. Aluminum deposited under these conditions tends to fill contact vias without the formation of voids. The low temperature deposition step can be initiated by depositing aluminum while a wafer containing the integrated circuit device is being heated from cooler temperatures within the deposition chamber.

Abstract: A semiconductor device for use as a bidirectional surge suppressor circuit has doped regions of substrate and epitaxial layers which result in a dual Zener diode arrangement having the Zener diodes associated in an opposite polarity arrangement. In an upper surface of the epitaxial layer, first and second regions of P type material are diffused with guard rings comprising P+ type material diffused around the first and second regions. The guard rings are heavily doped and extend much deeper than the relatively shallow junctions of P material. A channel stopper of N+ conductivity type material is diffused into the upper surface of the epitaxial layer to provide a channel stopper, or sinker, around both the first and second regions and their associated guard rings and, additionally, between the first and second regions. This structure provides several significant advantages including reduced current leakage reliability, uniform breakdown voltage, crack resistance and a smaller area needed to provide the required thermal capacity.
