Title: Crystal oscillation watch
Inventor: KUSAMA SABUROU
IPC: G04C10/00
Filed: 1978-07-05
Abstract: PURPOSE: To elongate the service life of electronic watch by employing silver oxide cell of 1V and by appying doubled voltage to a crystal oscillator for a prescribed period after the initial cell loading.  
     CONSTITUTION: When a cell is loaded, timers 2-5 start movements, and their outputs open and close gates 2-7, 2-8 for a prescribed period. Voltage of the 1V silver oxide cell 3 is doubled by the function of voltage doubler circuits 2-6 and starts and drives the crystal oscillators 2-1. After the elapse of a prescribed period, gates 2-7, 2-8 open and close, and the oscillators 2-1, which are in the state of stabilization, are driven by the voltage of 1V cell 3. Service life of the electronic watch is elongated by being driven by this 1V cell. Also, in case inverter which is different in scale-size is employed, the same result is obtained by switching gains.

Title: Rotor with permanent magnet of rotary electric machine
Inventor: NODA SHINICHI
IPC: H02K1/27
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To reduce magnetic noise due to the n-th order harmonics of an electromagnetic force with a simplified structure. SOLUTION: The rotor iron core 14 has the external circumference surface so that a ratio r/a of external circumference radius (r) of magnetic pole and deviation (a) between the center of external circumference radius and the center of rotor 12 satisfies -0.0097n3+0.426n2-6.278n+36. However, (n) is the n-th order harmonics as the target of reduction among the electromagnetic force developed in the gap between the rotor iron core 14 and stator iron core. With the structure explained above, since noise due to the harmonic element as the noise source among the electromagnetic force developed in the gap between iron cores can be reduced, noise generated from an rotary electric machine can be reduced effectively by forming the magnetic poles in the shape as explained above.

Title: Manufacture of resin cylindrical product and equipment to be used for it
Inventor: ANDO YASUNARI
IPC: B29C48/325
Filed: 1986-04-09
Abstract: PURPOSE:To manufacture a resin cylindrical product which is superior in roundness and straightness and is free from formation of marks of a split groove, by a method wherein a deep groove is provided on the fringe of an end face of an outlet of a die, a solid expansion material whose coefficient of linear expansion is high is enclosed and charged into the groove and the same is expanded through heating. CONSTITUTION:A back pressure ring 24 and bolt 24a are fixed to an outlet part 51 of a die made of a metal. At the time of extrusion molding of a molding material, heat to be given to a die 3 is transferred to the outlet part 51 of the die, a thermosetting urethane resin ring 53 arranged within the deep groove 52 through insertion is expanded drastically and an inner circumferential surface of the deep groove 52 is swollen out inwardly. In consequence of the above, contraction of the diameter of the outlet is performed inwardly by expanding the inner circumferential surface of the outlet in the outlet part 51 of the die. As the expansion is performed uniformly extending over the whole of the inner circumferential surface of the deep groove, a resin pipe which is superior in roundness and straightness becomes obtainable. Moreover, as a split groove is not used for the above product, a flaw or a protruded piece which is ascribable to the split groove is not generated and a resin pipe whose external appearance is favorable is obtained.

Title: Toroidal magnetic field coil unit
Inventor: MATSUKAWA MAKOTO
IPC: H05H1/10
Filed: 1993-04-08
Abstract: PURPOSE:To avoid the occurrence of quench phenomenon efficiently, to simplify a system, and to reduce its cost by installing an equivalent primary impedance reduction coil at a toroidal magnetic field coil. CONSTITUTION:An equivalent primary impedance reduction coil is placed externally to rapidly reduce current on quench protection in a toroidal magnetic field coil. Namely, a protection coil is placed so that it crosses the magnetic field created by the toroidal magnetic field coil in the toroidal magnetic field coil unit. When the toroidal magnetic field coil is used as a primary coil, the protection coil constitutes a secondary coil. When the protection coil is used as the secondary coil, a primary coil current moves to the secondary coil and the primary coil 9toroidal magnetic field coil) current is attenuated faster than that of the total magnetic energy transiently, thus securing the protection operation on quenching.

IPC: H05B41/32
Filed: 1984-04-24
Abstract: PURPOSE:To simplify circuit constitution by generating a light emission stop signal and a light emission restart signal repeatedly and repeating the impulsive light emission of a flash discharge tube. CONSTITUTION:A main switching element connected in series with the flash discharge tube 14 is opened on the basis of the light emission stop signal generated when the charging voltage of a main capacitor 3 attains to a specific level.
