Title: Method of making a composite abrasive wheel and mould therefor
IPC: B24D18/00
Filed: 1938-01-08
Abstract: 498,950. Grinding-wheels ; moulding. NORTON GRINDING WHEEL CO., Ltd. Jan. 8, 1938, No. 652. Convention date, Jan. 12, 1937. [Class 60] [Also in Group V] A composite abrasive wheel is made by moulding a heat-settable material to form a central support 15, and assembling the latter between a larger-diameter plate 16, slidable in a mould band 10, and a plate 14 which is of the same diameter as the support 15 and which is slidable in a ring 12 releasably secured in the band 10 flush with the lower surface of the latter. The plate 14, which is of the same width as the ring 12, is temporarily held above the lower surface of the band 10 by shims of predetermined thickness, and the annular space 18 thus provided is filled with a mixture of abrasive grains and a heat-settable material. On applying pressure to the plate 16, after removal of the shims, the mixture is compressed to form an abrasive rim on the support 15, of the same width as the latter. Heat is then applied to set the rim. The support may be heated to set it prior to assembly in the band 10, or it may be heated after compressing the rim thereon. In the latter case, the original width of the support is slightly oversize so that, during the pressing operation, it is compressed to size and its plastic flow assists in securing the rim thereto. On the completion of the operation, the ring 12 is released from the band 10 and the members 12, 14, 15, 16 are forced downwards through the band for removal of the completed wheel. The heat-settable material is a resinoid or vulcanizable rubber compound.

Title: Combined switch and fastener construction
IPC: H01H3/16
Filed: 1952-01-10
Abstract: 722,110. Retractive switches. LINREAD, Ltd. (Liley, J. W.). June 5, 1952 [Jan. 10, 1952], No. 776/52. Class 38 (5) A switch, suitable for operation by a door, comprises a spring-biased contact-carrying plunger 22 slidable within a hollow screw 12 which may be one of the screws securing a hinge 45, 48 to a door frame 46. In the form shown, the plunger 22 is metallic and carries an insulating head 28 on which is rotatably mounted a tubular contact member 36 to which a conductor 27 is attached. A spring 23 tends to move the member 36 into engagement with the conical end 17 of the screw 12 thus completing a circuit, but when the door is closed the portion 48 of the hinge presses the plunger into the circuit-open position shown. The arrangement provides for the screw 12 being turned without turning the member 36 and conductor 27 and screw, and switch and conductor 27 can all be drawn out through the hole in the door frame. In modification, Fig. 4 (not shown), an extension of the screw 12 forms the fixed contact and encloses the spring which is in tension instead of compression, and the moving contact takes the form of 'spring fingers. In another modification, the plunger is insulating, and in others, Figs. 6-9 (not shown), the plunger carries a bridging member adapted to bridge two fixed contacts connected to two leads.

Title: Aircraft guidance systems and apparatus
IPC: G01S13/76
Filed: 1975-01-07
Abstract: 1481351 Radio navigation DEFENCE SECRETARY OF STATE FOR 7 Jan 1975 [8 Jan 1974] 00902/74 Heading H4D To enable up to 200 aircraft approaching an airstrip to be sequentially interrogated to give range indicating responses and then information to be transmitted relatively to the aircraft to enable or cause the aircraft to line up for spaced, safe landings, an aircraft guidance system operates in two modes during repetitive epochs, Figs. 1, mode 1 being a secondary radar mode during which interrogation pulses (a) are transmitted and responses (b) are received and mode 2 being an information transmissions mode during which the messages are sequentially transmitted to the aircraft. The 60 interrogation periods are divided into first and second halves so that with each aircraft replying with a single pulse (a1) or not (a0) during each period, a response of 30 consecutive bits can be received from each aircraft as to identify, airspeed, destination &c. in each half. Fig. 2 shows at A1, A2, A3, A4, the start of responses 1111, 1011, 1101, 0011 from four aircraft. Allowing for a safety gap of 4 Ásec., the delay between the transmission of an interrogation pulse and a response pulse, is measured using sampling or counting pulses, e.g. 224 to an interrogation period. To obviate the chance of the responses of two aircraft on different bearings but at equal ranges overlapping, randomly chosen delays dt may be added to the response time of the aircraft, making the total delay (2(r)/(c)+ dt), the value of dt being signalled to the ground in the response message. The commencements of the two modes at the ground station are signalled to the aircraft by characterizing mode signals, the mode 2 signal ((a) Fig. 1), also carrying general (all aircraft data) viz name and address of station, runway in use, weather conditions. During mode 2200 messages of 93 bits each are selectively addressed and transmitted to the aircraft, giving 10 messages/sec. for each aircraft. The response pulses ideally enable the ground station to determine the elevation and azimuth of the aircraft. If however the pulses are too short, longer pulses (c) Fig. 1) at a different frequency F 2  are additionally transmitted by the aircraft. The ground station receiver employs swept gain ((d) Fig. 1) for the response pulses.

Title: Semiconductor device
Inventor: BONSHIHARA MANABU
IPC: H01L21/60
Filed: 1979-01-04
Abstract: PURPOSE: To easily detect an error in an electrode arrangement by constituting electrodes whose pitch is almost equal on an opposed side and whose total arrangement does not have a synmetric axis of rotation, of plural electrodes arranged in a square shape.  
     CONSTITUTION: Electrodes are formed on a substrate in a square shape with electrodes 200∼204 opposed to 209∼213 and electrodes 205∼208 opposed to 214∼217 at almost an equal pitch. Under this arrangement, if the electrodes are turned 90°, electrodes 204 and 213 have no overlapping corresponding electrodes. Consequently it is possible to easily detect an erroneous arrangement. However, if it is turned further 90°, the electrode overlaps completely, disabling detection of erroneous arrangement. Only one lead frame is available which corresponds to an electrode position. Therefore, if the electrode arrangement is redesigned so that the entire  arrayed shape may be of such configuration as to have no synmetrical axis of rotation, an error can be easily detected in the arrangement and therefore, erroneous  action or breakdown of the apparatus can be prevented.

Abstract: PURPOSE:To improve durability and to obtain an excellent image of a high density without having fogging by using a developer formed by coating a carrier by using a specific resin, incorporating such carrier into a toner, and adding fine inorg. particles having positive electrostatic chargeability in friction with the carrier. CONSTITUTION:The negative electrostatic latent image formed on the surface of a photosensitive body consisting of an org. photoconductive semiconductor is developed by a contact type magnetic brush developing method using the electrostatic image developer constituted by incorporating the carrier coated with a styrene/acryl (SAN) copolymer, the toner into which the SAN copolymer is incorporated, and the fine inorg. particles which are electrostatically charged positive by friction with the above- mentioned carrier into the developer. The positive triboelectrostatic charge of an adequate electrostatic charge quantity are surely imparted to the toner by the synergistic effect of the carrier, the toner and the positive-chargeable fine inorg. particles contained in the above-mentioned developer; inn addition, the good triboelectrostatic chargeability is not affected by environmental conditions such as high humidity. The good image of the high density having no fogging is thereby stably obtd. even after repetitions of many times without being affected by environmental conditions.

IPC: H01L29/78
Filed: 1988-01-07
Abstract: PURPOSE:To improve the efficiency of a semiconductor element by a method wherein, after the Al pattern of an MNOS structure element has been formed, the interfacial level introduced into an SiO2-Si interface is recovered in a simple manner by conducting a laser annealing from the surface side of the element. CONSTITUTION:After the Al pattern, namely, an Al gate electrode 6 and an Al wiring part 8, has been formed, a laser beam 11 of the wavelength of 160nm-1.2mum and the output of 10-150W/cm<2>.s is projected from the surface side of an element. The laser beam of the above-mentioned wavelength almost passes through SiO2, and it is absorbed by Si. The laser beam on the surface part of Al is reflected, the heat of the Al film passes through a silicon oxide film 4 from a substrate 3, it becomes superconductive and the temperature is suppressed. As a result, the laser beam 11 works on the silicon only in the vicinity of SiO2-Si interface, and the interfacial level changed by the damage received in an Al vapor deposition and an Al dry-etching processes can be recovered. As a result, the efficiency of the semiconductor element can be improved.

Filed: 1981-01-08
Abstract: PURPOSE:To eliminate error in an output voltage, by keeping an emitter current unchanged until switching, in a selection circuit consisting of a differential circuit and taking emitters of common connection as an output. CONSTITUTION:When an input V1 is greater than an input V2, a current I flows to transistors (TR) 21, 23 and the equal current I flows to TRs 24, 25. Current sources I1, I2 have the relation of I2 2I1=2I. In this case, a TR22 is cut off and a TR27 also cut off, and an output in accordance with the input V1 is outputted at a terminal VOUT. Taking V1 V2, a current flows to the TR22, the base potential of the TRs 26, 27 is almost equal, and the current I flows to the TRs 26, 27. Thus, the current I flows to the TR22. Since the current I flows to the TR21 until it cuts off, the error in output voltage is decreased when V1 V2.
