Title: Fault location methods and apparatus
IPC: G01R31/08
Filed: 1980-06-18
Abstract: A probe for sensing the direction of flow of an injected current pulse along a conductor of a circuit under test is linked to an ATE, to be triggered to inject the pulse during a test sequence at a step previously found by the ATE to establish a faulty state in the circuit. Thus, the faulty one of several components connected to a circuit node can be identified. The probe itself can also be used independently, and injects an approximately triangular-waveform current pulse which has a steep rising edge and a less steep falling edge, thereby inducing a voltage pulse which is asymmetric about the zero voltage level and thus permits discrimination of the direction of current flow. The probe may have a single current injection contact disposed between the limbs of a bifurcated core carrying a pick-up coil. <IMAGE>

Patent GB-2080832-A (GB)
Title: Process for cleaning a device
IPC: C23G1/02
Filed: 1981-07-31
Abstract: A device is cleaned by contacting it with a reagent. The device can comprise a soldered aluminium heat exchanger, and the reagent can be used to clean it after soldering. The reagent is passed in contact with the device for a time which is such that the reactivity increase of a unit volume of reagent, resulting from a temperature increase due to an exothermic reaction between the reagent and that device, is substantially balanced by a reactivity decrease caused by exhaustion of the reagent. Such a behaviour is useful when cleaning the interior of small components, since, with known reagents, the inlet gets excessively cleaned and the reagent is exhausted by the time it reaches the interior.

Patent GB-2118210-A (GB)
Title: Reflectors for passive display devices
Inventor: ELLIOTT GEORGE
IPC: G02F1/153
Filed: 1982-03-12
Abstract: An electrically non-conductive substrate (11) bearing thereon, preferably via an intermediate thin dielectric layer (12), a non-specularly reflective metal layer (13) itself covered by a thin layer (14) of a solid light transparent material having a refractive index of less than 1.4 is used as an internal non-specular reflector in display devices of the liquid crystal or electrochromic type. Such devices are generally operated in the reflective mode, in which the ambient lighting is transmitted through the device and reflected back out to the observer by a suitable reflective layer. Recently it has been suggested that there should be used an internal non-specular (Lambertian) metal reflector, but this type of reflector has a poor reflectivity in contact with most liquids, including liquid crystals, due to the so-called "window" effect. The provision of layer (14) removes this defect. <IMAGE>
Patent GB-2098042-A (GB)
Title: Fishing float
IPC: A01K93/00
Filed: 1982-05-06
Abstract: Line 18 from a fishing rod (not shown) extends through eyes 16 and 17 so disposed in friction component 11 of the float that the line must engage with the surface of the component 11 which is connected flexibly, e.g. by braid 19, to the bottom end of stem 12 of main buoyant member 10. Upon the line 18 and float being lowered into water 22, relocation of the line 18 permits weight 20 to draw it through the eyes 16, 17 until weight 20 touches silt or surface 23 under the water. Thereupon, application of slight tension to the line 18 raises the friction component 11 to ensure frictional engagement of the line 18 with the component 11. <IMAGE>

Title: Semiconductor memory device
Inventor: KOMORI KAZUHIRO
IPC: H01L21/8246
Filed: 1982-09-22
Abstract: In a memory device peripheral circuits energised by a low voltage are of CMOS construction while circuits energised by a relatively high voltage are formed of IGFETs having a channel of opposite conductivity type to the substrate. The memory cells M-CEL comprise non-volatile floating gate FETs. N-channel transistors Q1, Q2, Q3 are formed directly in the substrate and form the writing circuit which switches the high voltage supply Vpp. Transistor Q4 is of P-channel type and is formed in an N-well 3 and is arranged with N-channel transistor Q5 to form a CMOS input buffer energised from the low voltage supply. Other low voltage peripheral circuits, eg output buffers and address decoders, are also of CMOS construction. The use of N-channel transistors in place of CMOS for the high voltage circuits eliminates latch-up problems. <IMAGE>
