Abstract: 722,800. Warning and/or stop mechanism for feeding slivers, &c. ELECTRONICS (BRADFORD) Ltd., [formerly R. R. DEVELOPMENT LABORATORIES Ltd.], SNOWDEN, F., CAMPBELL, G. C. L., WALKER, N. A. D., and BARBER W. April 10, 1952 [Jan. 10, 1951], No. 687/51. Classes 120 (2) and 120 (3). A device for detecting and indicating faults in the feed of slivers, yarns, &c., comprises a pivotal or rotatable element arranged below one or more slivers, &c., and having a toothed or other similar surface adapted to take a hold on a sliver, &c. end falling across it and to be moved substantially solely by the drag caused thereby so as to operate a switch in an electrical circuit which includes electrically operated mechanism for giving a warning or for stopping the machine, the element being mounted to pivot or rotate from a position in which a broken sliver &c. is dragged into or on to the toothed or similar surface to a position in which the sliver, &c. is dragged out of or off such surface again. As shown the movable element is in the form of a comb 1 extending below slivers 3. Should a sliver break, the end falls across the comb 1 and the drag exerted thereon rotates it into the dotted position shown and this operates a micro or mercury switch in the switch box 11, in circuit with warning or stop mechanism.

IPC: C07C43/20
Filed: 1987-01-06
Abstract: PURPOSE:To obtain the titled substance useful as a coloring promoter for pressure-sensitive paper, raw material for aromatic polymers, etc., readily in high purity and in high yield, by reacting a monoalkoxynaphthol with a dialkyl sulfate in an inert water-miscible solvent in the presence of a base. CONSTITUTION:A monoalkoxynaphthol (preferably 4-alkoxy-1-naphthol) is reacted with a dialkyl sulfate (e.g. dimethyl sulfate) in an inert water-miscible solvent in the presence of a base (preferably alkali metallic hydroxide) at 40-50 deg.C for 0.5-1hr to give the titled substance. A mixture of mono alkoxynaphthol, dialkoxynaphthol and a small amount of dihydronaphthalene obtained by reacting dihydronaphthalene with an alcohol in the presence of a catalyst may be reacted with dialkyl sulfate. By these methods, the amount of expensive dialkyl sulfate used can be reduced as much as possible.

IPC: H03L7/16
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To make an S/N high and to make a separating shield and an amplifier simple and inexpensive. SOLUTION: A variable frequency divider 12 undergoes frequency dividing of an output of a VCO 31; a frequency converter 33 converts the output into a low frequency with an output of a direct digital synthesizer 32; a comparator 13 performs phase comparison of the frequency conversion output with a reference signal of a reference oscillator 14; and the comparison output is supplied to the VCO 31 through a loop filter 15 to control the VCO 31. For instance, 30 to 100MHz signal outputs an oscillation output of the VCO 31 to an output terminal 24 through a switch 34, and 100kHz to 30MHz signal outputs from the DDS 32 to the terminal 24.

Title: Field effect transistor
Inventor: TSUBAKI KOTARO
IPC: H01L29/423
Filed: 1985-01-08
Abstract: PURPOSE:To enable a mutual conductance larger than conventional to be obtained by the variation of the effective gate length with gate voltage, by a method wherein the direction of a groove forming a stripe end of a gate electrode is made vertical to the line combining a source electrode with a drain electrode. CONSTITUTION:Hetero junctions made of the first semiconductor layer 12 and the second semiconductor layers 13, 14 of the same conductivity type having large differences in electron affinity are formed. In the surface of the second semiconductor layers, e.g. AlGaAs layers 13, 14 of small electron affinity formed on the first semiconductor layer, e.g. GaAs layer 12 of large electron affinity, a gate electrode 17 having many stripe ends 17a is formed. The thicknesses of the second semiconductor layers 13, 14 are made large at the ends 17a enough to gate-voltage-control the number of carriers 18 accumulated in the interface between the first semiconductor layer 12, and the direction of grooves forming the ends 17a is made almost vertical to the line combining the source electrode 15 with the drain electrode 16. This construction causes the effective gate length to vary with gate voltage, and the mutual conductance with changes of the gate length; therefore, the increase in mutual conductance Gm can be contrived.

Title: Digital cell call repeating system
Inventor: MATSUZAWA HIROSHI
IPC: H04B7/24
Filed: 1992-01-07
Abstract: PURPOSE:To shorten the time of collecting polling response and to reduce the malfunction due to the interference by attaining the line repeating to the master station for the constant time from the point of time monitoring the polling command from the master station. CONSTITUTION:A polling command monitor means 4 of a repeating station 2 sends the monitor output when monitoring the polling command in the reception signal from a master station 1. A repeating operation control means 5, when the monitor output from the means 4 is applied, controls the operation of the required section to make the repeating possible only for the set time required for the polling response (for example, for three seconds). A slave station 3, when detecting the polling command for the its own station, sends the polling response as a transmission signal to the repeating station 2 without adding an interruption command. The repeating station 2 sends the polling response which is received at the repeating operation state as it is to the master station. As a result, the time of collecting the polling response is shortened and the malfunction due to the interference is reduced.

Title: Production of color filter
Inventor: AOKI AKIRA
IPC: H01L29/786
Filed: 1990-01-08
Abstract: PURPOSE:To prevent the deterioration of display quality by making the size of the pattern of a photomask for a color filter smaller than the designed size of the color filter. CONSTITUTION:The size of the pattern of a photomask PMS for a color filter FIL is made smaller than the designed size of the color filter FIL. Since the sizes of the patterns of photomasks PMS1, PMS2, etc., are made smaller than the designed sizes of a red color filter FIL(R), a green color filter FIL(R), etc., the adjacent color filters FIL do not overlap each other and the ends of the color filters do not form foreign matter by peeling. Ununiformity in color is not caused and the deterioration of display quality can be prevented.

Abstract: PURPOSE:To increase the self-priming capacity of the pump by a method wherein fluid, remaining in the space of the inside of the pump, is introduced effectively into the part of a seal surface to secure the amount of the fluid existing on the surface of the seal. CONSTITUTION:When the operation of the pump is stopped, the fluid, staying in the space A22 and a magnet accommodating space, flows into a pump operating chamber 20, since a groove is provided at the substantially same level of the pump operating chamber 20. The fluid is sufficiently secured on the seal surface under a condition that the fluid is secured considerably in the pump operating chamber 20, therefore, the sufficient self-priming property may be secured.

Abstract: PURPOSE:To make a focus control unnecessary, and to improve a positioning accuracy of a recording medium by separating a mechanism for stabilizing a flexible recording medium and an optical head, and executing a tracking and a seeking in a state that the stabilizing mechanism is fixed. CONSTITUTION:A recording medium 40 is fixed to a revolving shaft 12 through a hub 11, and to its upper part, a fixed plate 41 having a transparent spherical part 42 is fixed. When the recording medium 40 rotates, the recording medium 40 is attracted to the fixed plate 41 by an air dynamic action, and profiled and deformed to a shape of the spherical part 42. On the other hand, a tracking and a seeking are realized by a rotation of only an optical head, a medium supporting system consisting of the recording medium 40, the fixed plate 41 and the spherical part 42 is not varied, and even if the optical head 20 rotates, a relative position relation of the optical head 20 and the recording medium 40 is constant, and accordingly, even if the tracking and the seeking are executed, an optical path length between the recording medium 40 and an objective 27 can be held at a fixed value with a high accuracy.
