Title: Floppy disk device
Inventor: SANO KIYOSHI
IPC: G11B5/465
Filed: 1985-05-29
Abstract: PURPOSE:To prevent an erasure head from being affected by magnetization by feeding an alternating attenuating current after signal erasure is completed by the erasure head and generating an alternating attenuating magnetic field in a head core for erasure, and converging it on the magnetizing level in the core. CONSTITUTION:A recording circuit 4 has a current source which processes and inverts an input digital signal into a recording signal and supplies it to an R/W head 1, and a reproducing circuit 5 amplifies and processes the reproducing analog output signal of the R/W head 1 and outputs a digital reproducing signal. An erasure control circuit 6 is provided with a powder source which feeds a current to an Er head 2 during recording with an R/W switching signal. The alternating attenuating current is flowed to the Er head 2 after erasure is completed to converge the current to zero and then the magnetizing level in the core decreases according to the attenuation of magnetic flux and converges to the zero level, so the magnetization of the Er head 2 is minimized. Consequently, the influence of magnetization of the erasure head is eliminated during recording and reproduction to prevent a reproducing output voltage from dropping and asymmetry from deterioration.

Filed: 1977-09-22
Abstract: PURPOSE: To maintain developing effect constant by respectively controlling the toner of the mixed developer of toner and carrier according to its concentration and carrier according to the change in developer volume and replenishing these respectively independently.  
     CONSTITUTION: A toner replenching device 3 is provided with mixers 13, 14 in a hopper 3c and a feed screw 3b in the lower part. A toner concentration decrease signal causes its driving part 9 to respond to revolve the screw 3b, which in turn charges toner into the opening 2a of a developing device 2 through replenishment hole 3a. A carrier replenishing device 4 is provided with a feed screw 4a in the lower part of a hopper 4c and its driving part 5 responds to the replenishment signal having detected the change in devoloper volume and causes the screw 4a to revolve, thus charging carrier into the opening 2b of the developing device through replenishment hole 4b. The toner and carrier having been charged are mixed and agitated by the screw 2c of the developing device. Hence, the toner and carrier of the two component type developer are replenished respectively separately and the developing effect is maintained constant

Title: Digital-to-analog converter
Inventor: KAWASHIMA KOTOJI
IPC: H03M1/06
Filed: 1980-08-19
Abstract: PURPOSE:To reduce the control error and to increase the control performance, by setting a digital value corresponding to a rated operation signal of a device to be controlled at a location shifted from the center. CONSTITUTION:When a digital signal is inputted, digital switches S1-Sn corresponding to each bit are operated, and an analog voltage is produced at an output  V0 of the circuit network consisting of resistors R1-Rn. This analog voltage makes control of the device. In this case, a digital value corresponding to the rated operation signal of the device to be controlled is shifted from the center of the control range of the circuit network. As a result, even if there is an error in the resistors, the malfunction due to an error caused at the center of the rated operation signal of the device to be controlled can be prevented and the manufacture can be made with low cost since the error of the resistance value can be permitted greatly.

Title: Hydraulic pressure protecting circuit for compressor for refrigeration
Inventor: KEIDA TOSHIYUKI
IPC: F04B49/02
Filed: 1982-07-02
Abstract: PURPOSE:To prevent the seizing of a sliding part for the compressor due to the decrease of the hydraulic pressure by a method wherein a delay relay is operated to start or stop the compressor intermittently when the hydraulic pressure is not rising up after a given time is elapsed. CONSTITUTION:When the hydraulic pressure has not risen up after the given time Ta has been elapsed, the delay relay T is operated at a time t1. As a result, a contact T2 is opened and the contacts of a twin timer TT are made active, therefore, a main relay MC is excited intermittently. According to the excitation, the compressor CM repeats starting and stopping intermittently so as to be rotated for 7sec and stopped for 5sec, for example. Thus, the compressor is started and stopped intermittently, therefore, the danger of seizing of the sliding part of the compressor due to the decrease of hydraulic pressure may be reduced compared with the case, in which the compressor is operated continuously.
