Title: Contactless capacitive finger operated switch - depends on change in capacitive impedance rather than fixed threshold levels
IPC: H03K17/96
Filed: 1970-09-30
Abstract: The switch is especially directed at telephone systems. A capacitance accessible to an operator in an unspecified way, is part of an a.c. excited circuit linked to the base of a transistor. In the emitter of this transistor there is a chain of resistors and capacitances across some of which other transistors are connected. A d.c. voltage is established in this chain in quiescent conditions, but if a capacitance change occurs - when a finger is applied - one of these transistors in the chain switches on and by activating a feedback network changes the chain impedance so that the feedback amplifier remains activated until another considerable capacitance change occurs - on the removal of the finger. The output of the feedback amplifier also serves as the switch output.

Title: Reel of adhesive plaster - has mutually offset reel flange parts, divided by narrow slits at body corners
IPC: A61F15/00
Filed: 1970-10-27
Abstract: Reel of adhesive plaster for a motor vehicle first aid box, with a polygonal reel body as in 2026338, has the body mfrd. in a collapsed state, with the reel flange divided in the region of the corners by narrow slits. The reel flange parts are mutually offset in the region of the fold plane by the thickness of the reel flange. Preferably the flange parts offset w.r.t. the carrier sleeve bear stops on the outside, to limit folding of the sleeve in the region of the fold plane to the angle given by the folded-out polygon. The wound-on strip can be protected on all sides by the flange parts when the reel body is folded.

Title: Optoelectronic thickness or width gauge - has HF oscillating laser scan with differentiated pulse driving display
IPC: G01B11/02
Filed: 1971-11-22
Abstract: The opto-electronic thickness gauge is capable of resolving wide variations of thickness over a large area of the workpiece. The output of a square-wave oscillator running at several kilohertz (7) is converted to a sawtooth or triangular waveform (8) to drive a piezo-electric scanning mirror (10). The oscillating mirror reflects the output of a continuous-wave laser (12) onto the surface of the specimen (13, 27, 28). The scattered beam is focussed onto a detector (17) placed at a known distance from a reference plane parallel to the workpiece. The amplified output of the detector is converted to a pulse (20) whose leading edge is differentiated (21) to drive a discriminator (22). The discriminator output is differentiated (23) and connected to the generator. A second output is integrated (24) and drives digital (25) and analogue display devices (26).

IPC: H04N3/185
Filed: 1982-02-15
Abstract: A deflection generator of a television receiver is coupled to a deflection winding for generating scanning current during a deflection cycle. The generator includes a retrace capacitor coupled to the deflection winding for forming a retrace resonant circuit therewith to produce a retrace pulse voltage during a retrace interval of the deflection cycle. An inductor and another capacitor form a second resonant circuit that is coupled to the retrace resonant circuit. A switching arrangement is coupled to a source of energy and the second resonant circuit in a push-pull configuration. The switching arrangement is responsive to a deflection rate switching signal to store during trace a controllable amount of energy from the source in the second resonant circuit. This stored energy is then transferred to the retrace resonant circuit during the retrace interval to replenish losses sustained during the deflection cycle.

Abstract: PROBLEM TO BE SOLVED: To prevent the electrostatic breakdown of a semiconductor chip in a resin sealing process with molding resin when manufacturing a BGA(ball grid array). SOLUTION: On an upper and a lower face of a circuit board 25a, circuit patterns 21a, 21b are formed respectively. On the circuit pattern 21a, protective films 22a and 23a are formed in order. A protective film 22b is formed on the circuit pattern 21b and a land 24 is extended from the circuit pattern 21b. The protective films 23a has a conductivity. Because of this structure, when the circuit board 25a is released from an upper mold 40 after sealed with molding resin, generation of static electricity is suppressed. Therefore, static electricity applied to a semiconductor chip 30 is reduced and the electrostatic breakdown of the semiconductor chip 30 can be prevented.

The bolt (5) used as the bearing of the lever (4) is borne in two side walls (9, 10) running parallel to an opening (6) in the housing (1), and has two regions (14, 19) of different diameter. The recess (20) between the two diameters is located in front of the rear side surface (21) of the front housing side wall (9) and, in the rear housing side wall (10), there is inserted a sleeve (15) whose end face (17) is located in front of the housing side wall (9) and, together with the recess (20) in the bolt (5), forms resting surfaces for the lever (4) of the intermediate transmission. <IMAGE>

Abstract: PURPOSE:To simplify process for production and to improve pressure resistance by fitting the edge part projected at the open end of a tank body into the groove part formed at the circumferential edge of a tube plate, deforming plastically the rising surface in the groove part by a caulking member and subjecting further the same to brazing. CONSTITUTION:A groove part 5 having a U-shaped section is provided to the circumferential edge of an aluminum alloy tube plate 3 and a brazing material is coated on the rear side thereof. Fins 1 are placed between flat tubes 2 in press contact therewith and both ends of the tubes are passed through the plate 3. A projecting part 7 is provided to the open end of an aluminum tank body 6 coated externally and internally with the brazing material and the part 7 is superposed on the base 4 of the part 5 and is placed on a supporting base 14. The rising surface 9 of the part 5 is pressed by a caulking member 8 to deform plastically a crest part 11 at every prescribed interval. The entire part is thereafter put into a vacuum furnace to melt the brazing material deposited on the body 6 and the plate 3, by which a heat exchanger is completed. The tank body and the tube plate are thus adhered tightly to each other by one time of caulking process, by which the brazing quality is improved.

Patent JP-H087947-B2 (JP)
IPC: H04L7/02
Filed: 1987-04-09
Abstract: A sampled synchronous transmission signal Vt is represented by a series of samples J at equidistant sampling instants. A computing circuit 5 computes the positions R of the sampling instants relative to the rising edges of a virtual reference clock Cref which is phase-locked to the channel clock. For each sampling instant the position R is determined on the basis of the position R of a preceding sampling instant and a measure Q of the difference in time between the sampling interval T and the period L of the virtual reference clock Cref. From the values of the successive samples J an interpolation circuit 2 derives the positions N of the detection-level crossings by the transmission signal Vt, which crosssings represent a fixed phase position of the channel clock. After each detections-level crossing the measure Q of the time difference is corrected by means of circuit 3 and 4 depending on the difference between the positions N and R. A data recovery arrangement recovers the data depending on the values determined for the positions R.

Abstract: The invention relates to a device for opening of doors. Electromechanical systems contain many expensive components and are thereby expensive to manufacture. Installed electromechanical systems are expensive in operation by virtue of the high and energy-demanding friction which always are present in mechanical constructions. The present operating device is less energy-demanding by the formed transmission of power via two piston-like parts ( 5 and 6 ). A driving device ( 2 ) is arranged to drive the piston-like part ( 5 ) and the second piston-like part ( 6 ) is connected to an operable element.
