Title: Spring brake
Inventor: SUGAI HARUO
IPC: F16D49/02
Filed: 1981-04-27
Abstract: PURPOSE:To achieve the strong braking force in both rotary directions of a rotary shaft, by means of a pair of twisted coil brake springs having different winding directions. CONSTITUTION:Both release rings 7, 8 are coupled through a pinion 9 at the  position where the braking is applied in the forward/reverse rotation of a rotary shaft 3, and when functioning a solenoid 21 to rotate one release ring 7 against the resilient force of a brake spring 5 having one end stopped to the release ring 7 the other ring 8 will also rotate against the resilient force of the brake spring 6 by means of a pinion 9. Consequently the diameters of the spring brakes 5, 6 are lengthened thus to enable the free rotation of a movable hab 4 or the rotary shaft 3.

Title: High efficiency rapid start type fluorescent lamp
Inventor: EBARA HIROYUKI
IPC: H01J61/72
Filed: 1979-05-25
Abstract: PURPOSE:To obtain high efficiency without damaging rapid start chracteristic by enclosing the mixed rare gas as starting gas which contains a specific amount of Xe, and Ne and Ar as the rest, in a bulb and has the ratio of Ar less than a specific amount of Ne. CONSTITUTION:Into the bulf of a fluorescent lamp, the mixed rare gas which contains 10-40% by volume of Xe, and Ne and Ar as the rest and has the ratio of Ar in 3% or less of Ne is enclosed as starting gas with a proper amount of mercury. When the ratio of Xe in the enclosed gas exceeds 40%, the lamp impedance decreases and the lamp current increases, and a stabilizer having rated value cannot withstand the current, and also the optical output of the lamp decreases. When the ratio of Xe is less than 10%, the consumption of electrode is remarkable, and the life of lamp is shortened. By keeping the ratio at a level described above, high efficiency can be obtained without deteriorating rapid starting characteristic.

Title: Cassette tape recorder
Inventor: SATOU KATSUYA
IPC: G11B15/02
Filed: 1979-05-28
Abstract: PURPOSE: To realize the selection for the desired position by skipping over the several non-recorded parts by releasing the holding force of the solenoid at the area of the non-recorded part which is set via the preset means at the reproduction time of the tape recorder.  
     CONSTITUTION: When the reproduction is given after presetting the music, the magnetic tape is rewound. And thus the non-recording of the magnetic tape is detected by record/reproduction head 13 and via detection circuit 78. With actuation of music selection circuit 72, the electric conduction of solenoid 62 is broken. Thus the holding force is cancelled to release hooking plate 55 to return music selection rewinding operation component 51 to the non-operation position. Thus the reproduction state is secured automatically. In case the reproduction is desired for the desired recorded part by skipping over several recorded parts without giving reproduction to the immediately preceding part at the music selection time, preset button 83 is pushed. Thus the automatic switching is given to the reproduction at the preset non- recorded part, ensuring the suited controllability.
