Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an α-bromo, ω-chloroalkane by which the α-bromo, ω-chloroalkane is cheaply and easily obtained by reacting α,ω-dichloroalkane with α,ω-dibromoalkane. SOLUTION: The objective α-bromo, ω-chloroalkane of the formula Br(CH2 )n Cl [(n) is 4-12] is obtained by reacting α,ω-dichloroalkane with α,ω- dibromoalkane in an organic solvent at 60-200 deg.C in the method for producing an α-bromo, ω-chloroalkane. The organic solvent is a non-protonic organic solvent having >=20 dielectric constant at 20 deg.C and containing nitrogen or sulfide and exemplified by N,N-dimethylformamide, N,N-dimethylacetoamide. The α-bromo, ω-chloroalkane is useful as a raw material for an organic synthesis and an intermediate for agrochemicals and medicines.  The highly pure objective product is easily isolated by rectifying the reaction product after the reaction and the method is also economically excellent because the α,ω-dichloroalkane, α,ω-dibromoalkane and the organic solvent removed by the rectification are reused.

Title: Magnetic recording/reproducing apparatus
Inventor: CHIBA KOJI
IPC: G11B15/46
Filed: 1994-09-07
Abstract: PURPOSE: To let a changing amount of a wound diameter of a tape keep up with a change of the running speed of a head, by counting a count of pulses of a frequency proportional to a rotating speed of one reel, correctly detecting the running speed of the tape, controlling a rotary cylinder, and keeping a relative speed of the head and the tape constant. CONSTITUTION: While a magnetic tape 1 runs at a predetermined speed V0, a cycle T0 of pulses of a frequency proportional to the rotating speed of a reel from a signal generator 30 is detected by a period detector 31 and stored in a memory circuit 32. Then, the tape 1 is transferred at an optional speed. A changing amount >=R of the diameter of the reel of the tape is calculated at a calculator 34 from the counted number of output pulses of a counter 33, and a correction amount >=T for the period proportional to the >=R is obtained at a period change calculator 37. An adder 35 adds the period T0 and the correction amount >=T, and inputs to a speed detector 36. A ratio of the period and an output period Tn of the period detector is multiplied by V0, thereby detecting a running speed Vn of the tape 1.  A cylinder speed calculator 72 calculates a target rotating speed based on the Vn and controls a cylinder 70 accordingly.

Title: Cassette type recording and reproducing device
Inventor: MATSUDA TAKASHI
IPC: G11B15/675
Filed: 1988-08-30
Abstract: PURPOSE:To easily eject a cassette from a cassette holder with a simple constitution by ejecting the cassette in the cassette holder with a toggle spring in which the direction of repulsive force is reversed in the case of performing a cassette ejecting action. CONSTITUTION:When a driving mechanism is driven and an arm 12 turns clockwise, the cassette holder 2 moves in a vertical upward direction and moves in a horizontal direction in the midst of movement. As the arm 12 turns more clockwise and the cassette holder 2 moves in the horizontal direction, 1st and 2nd levers 6a and 6b also turn. Then, the toggle spring 20 exceeds a dead point by the rotation of the 1st and the 2nd levers 6a and 6b just before the cassette 1 reaches an inserted position and the repulsive force of the spring 20 is reversed in a direction shown by an arrow I. The 1st and the 2nd levers 6a and 6b press the cassette 1 from its back so as to eject the cassette 1 from the cassette holder 2. Thus, the cassette can be easily ejected from the cassette holder in the case of performing the cassette ejecting action.

Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a liquid for improving the combustion efficiency of a fossil fuel and for markedly reducing the generation of e.g. noxious gases with a view to solve the problem that fossil fuels (petroleum and coal), which are used as fuels, generate very noxious nitrogen oxides, sulfur oxides, carbon and carbon monoxide when burnt, and that constructions are corroded or deteriorated by e.g. the acids, sulfur, etc., and acid rain results in a serious change in lakes, swamps, animals, vegetables, fishes. SOLUTION: A harmless fermentation product is added to a fossil fuel (e.g. petroleum or coal). In a boiler or an engine, the combustion of the fossil fuel becomes nearly perfect combustion. Although a boiler fired with a fossil fuel exhausts a lightly blackish smoke, it turns almost colorless. In an automotive engine, nitrogen oxides, sulfur oxides, hydrocarbons and carbon monoxide are reduced by 42%, 80%, 56% and 56%, respectively. The combustion efficiency can be improved by 30-55%.

Abstract: PURPOSE:To eliminate effectively a false signal shading by making a redistribution of secondary electrons generated at scanning to a target plane over the entire scanning plane uniform, and uniforming a false signal based on the redistricution of the secondary electrons. CONSTITUTION:The locus of an electron beam scanning the image pickup tube target plane is shown in Fig. (a). Solid lines show the scanning electron beam of the signal reading period and broken lines show that of the blanking period. The timewise change of the scanning electron beam current corresponding to the locus is shown in Fig. (c), and while the electron beam is cut off at horizontal and vertical blanking periods conventionally, the scanning electron beam during the horizontal blanking peiod is increased linearly from the beginning of the scanning to the end of the scanning without cutting off the beginning of the scanning to the end of the scanning without cutting off in this system as shown in Fig. (c). Thus, the false signal based on the redistribution of the secondary electrons is uniformed and the false signal shading is eliminated.
