Title: Production of mixed hydrocarbon solvent
Inventor: TORII MICHIAKI
IPC: C10G7/00
Filed: 1986-07-04
Abstract: PURPOSE:To prepare a non-polluting solvent of less odor exhibiting high solvency and having no harmful effect on the human body, by conducting nucleus hydrogenation of a kerosense fraction which is within a particular fraction range, removing paraffins with a molecular sieve and then conducting the rectification of the bottom oil. CONSTITUTION:Nucleus hydrogenation treatment of a kerosene fraction which is within a b.p. range of 150-300 deg.C is conducted at a temp. of 100-300 deg.C under a pressure of 30-100kg/cm<2> using a metal catalyst generally employed for nucleus hydrogenation of an aromatic ring. Subsequently, at least portions of n-paraffins contained in the kerosene fraction are separated and removed using a molecular sieve comprised of a synthetic zeolite. The bottom oil thus obtd. is rectified, thereby obtaining the desired solvent which has a b.p. of 160-300 deg.C, comprises 30-80wt% naphthenes, 0-20wt% n-paraffins, 15-40wt% isoparaffins, 15wt% or less tetralins, and 0-10wt% arom. hydrocarbons and is free from naphthalene and biphenyls.

Title: Noise eliminating circuit
Inventor: TAURA KENICHI
IPC: H03G3/34
Filed: 1981-10-02
Abstract: PURPOSE:To effectively eliminate noise while deterioration in tone quality is suppressed, by changing the noise eliminating period in accordance with the noise existing period, and interpolating a signal during the period. CONSTITUTION:A sound signal 200 and a noise eliminate signal 201 which shows where noise exist in the sound signal 200 are successively fetched into an analog shift register 20 and a shift register 40 which are controlled by a clock 212 of a clock generator 140, respectively. A controlling circuit 60 outputs the output from the analog shift register 20 through an interpolating circuit 110 while the noise eliminating signal is ''1'' indicating that no noise exists. While the noise eliminate signal is ''0'' and indicates existing of noise, the interpolating circuit 110 does not accept the output of the analog shift register 20 during this period by the output of the controlling circuit 60, and outputs while linearly interpolating between analog signal levels before and after the output.

When a foreign matter is present in the second insulating layer 5, and an electric field is collected to this foreign matter to produce an electric tree, a high electric field is collected to the tip of the electric tree to extend the electric tree since the inner surface of the electric tree is carbonized and made conductive.  When the electric tree reaches the semiconductive layers 4, 6, the tip of the electric tree is substantially equalized to the potential of the semiconductors 4, 6, so that the electric tree can be prevented from being extended to lead to a dielectric breakdown.

Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To improve cooling effect with a simplified structure by cooling the apparatus as a whole with a propeller with rotation of a magnetic disk by fitting a propeller to a rotating shaft of a drive motor for magnetic disk rotation. SOLUTION: In a hard disk apparatus HDD1, a thinner propeller 5 is fitted to a motor shaft 3a projected above a protection cover 4 of a drive motor 3.

And on top of the non-single-crystal silicon thin film 3, another SiO2 film 4 is deposited which would serve for a reflection preventing film. Thus, a sample 8 is obtained. A heat-sink dielectric 6 is attached tightly to the top of the sample 8. To make the polycrystal silicon layer 3 to be a single crystal one, energy beam 7 is cast on the surface of the sample 8. The whole surface of the sample 8 is scanned by the energy beam 7 to obtain a single-crystal silicon thin film 5. After that, the heat sink 6 is removed from the sample 8.

Title: Prize ball payout device for pinball game machine
Inventor: MATSUMOTO MICHIKO
IPC: A63F7/02
Filed: 1995-05-31
Abstract: PURPOSE:To detect ball exhaustion on the upper part side of a prize ball payout means, and also, to surely detect ball clogging without generating malfunction by individual ball passing a prize ball reservoir passage regardless of a payout system. CONSTITUTION:The prize ball reservoir passage 34 is filled with prize balls A in an ordinary state, and the prize ball A in a moderately inclining passage part 34a on the upper part side of the prize ball reservoir passage 34 pushes up a sensing arm 92 around a pivot 93. When the prize ball A in the prize ball passage 34 on the prize ball payout part 36 side from the sensing arm 92 is exhausted, the sensing arm 92 is protruded over the moderately inclining passage 34a by descending around the pivot 93, therefore, a ball exhaustion confirming switch 39 detects the exhaustion of the prize ball in the prize ball reservoir passage 34 interlocking with the sensing arm 92. Since the sensing arm 92 is formed in lengthy shape in the direction of passage of the prize ball reservoir passage 34, and also, it is supported pivotally with the pivot 93 on the upper side in such a way that it can be freely rocked in the up-and-down direction, the sensing arm can be rocked smoothly corresponding to the presence/absence of the prize ball in the moderately inclining passage part 34a.
