Title: Amorphous alloy for transformer
Inventor: NANUN MICHIHIKO
IPC: C22C45/02
Filed: 1979-08-28
Abstract: PURPOSE: To enhance the amorphism forming capacity and thermal stability of an amorphous alloy for a transformer iron core by converting the alloy into an Fe- Si-B-C amorphous alloy having a specified composition.  
     CONSTITUTION: This amorphous alloy for a transformer iron core has a composition represented by formula I (where a+b+c+d=1, b=0.02W0.08, c=0.08W0.17 and d=0.01W0,08). This alloy is more easily made amorphous as compared to an Fe-B-C alloy, and it is superior to the Fe-B-C alloy in thermal stability. This alloy has a higher crystallization temp., undergoes a much smaller change in the coercive force with the passage of time, e.g., at 140°C, and is thermally stable. On the othr hand, the saturation magnetic flux density is hardly lowered, and the addition of Si results in enhanced exciting characteristics, so this alloy is advantageous as a transformer iron core material.

Abstract: PURPOSE:To attain a telephone call system where the transmission phase of a call signal causes no overload of a signal device, by collating the call signal phase information received cyclically from a main controller with the stored call phase information and connecting the call signal to a called telephone when coincidence is obtained from said collation of information. CONSTITUTION:When a change in signal phases, for example, to the 2nd phase from the 1st phase is detected, a telephone TEL counter set within a secondary controller SPU1 is set at 1 to designate a telephone TEL11 of the device number ''1''. Then the allocation signal phase information B stored in the designated telephone number ''No.1'' is read out and collated with a phase A obtained after change. In this case the information B is set at ''2'' and A=B is satisfied since the phase A is set at ''2'' after change. Then a signal switch S11 of the TEL11 corresponding to the value ''1'' of the TEL counter is turned on. Thus a signal device SIG is connected to the TEL11 in the 2nd phase, and call signals are transmitted.

Title: Image forming apparatus
Inventor: YOSHINAGA KENJI
IPC: G03G15/08
Filed: 1986-05-16
Abstract: PURPOSE:To enhance an image forming speed, by a method wherein in transferring from a developing operation of a first set successively performing development by a plurality of developing agents to the developing operation of a second set, a developing operation of the second set is started from the point of time when the first developing agent of the second set arrives at a developing position in the first place. CONSTITUTION:For example, developing devices corresponding to four colors are mounted on a rotary body 4. By applying a power source, the rotary body 4 moves to a home position in a step 101. In a step 103, it is judged whether all of color constituting data bi are zero or not and, if either one of them is 1, an image to be recorded is present, therefore, operation advances from a step 104 to a step 109 and, for example, the developing device Y is moved to a developing position to perform developing operation. In a step 112, it is judged whether further continuation of an image forming process is necessary or not and, if it is necessary, the operations of steps 105-112 are repeated. In case of bi=0, operation jumps from the step 106 to the step 12 and no developing operation is performed. In case of i=4, operation returns to the step 102 and there is no operation for allowing the rotary body 4 to return to a home position at every multiple transfer image.

Title: Narrow band laser device
Inventor: NISHIDA NAOTO
IPC: H01S3/08
Filed: 1989-04-28
Abstract: PURPOSE:To eliminate draft of central wavelength of a laser light due to temperature rise of an enlarging optical system even if a laser operation is continued by providing means for controlling supply of cooling medium to the system. CONSTITUTION:A laser light L output from a laser exciter 11 is reciprocated between an output mirror 14 and a diffraction grating 16 to be narrowed, output from the mirror 14, and introduced into an exposure unit 18. In this case, the light L heats the prism 17 of an enlarging optical system 15. In this instance, cooling medium held at a predetermined temperature by a temperature regulator 27 is fed to a holder 25 for holding the prism 17. Thus, since the prism 17 is cooled by the medium through the holder 25 and maintained at predetermined temperature, it is not affected by the thermal influence of the light L, not raised at its temperature, and not varied at its refractive index. Thus, the central wavelength of the light L output from the mirror 14 is not drifted by the variation in the refractive index of the prism 17.

Abstract: PURPOSE:To form a sharp toner image stably by producing a unidirectional electric field in a development area previously and then varying the oscillating electric field continuously or stepwise before a latent image on an image carrier reaches the development area. CONSTITUTION:The surface of the photoconductor layer of the image carrier 3 which is rotated as shown by an arrow A and charged uniformly and electrostatically is exposed to an image by a laser beam scanner with a binary-coded signal, thus forming a latent image. A developing device has a developer carrier 15 of a nonmagnetic material applied with a bias voltage from a bias power source 11 to generate an electric field in the development area before the carrier whose base part is grounded. Before the latent image reaches the development area, the carrier is applied with a DC voltage previously and an AC voltage with a constant period is increased in amplitude gradually and superposed, so that the latent image formation area of the carrier 3 passes through the development arear when the amplitude of the AC voltage attain to a specific value. Thus, fog-free toner development is carried out without scattering toner.
