Title: Recorder
Inventor: TOHARA MASAHIRO
IPC: G01D3/00
Filed: 1988-02-10
Abstract: PURPOSE:To obtain a recorder which performs high-accuracy recording without any need to adjust the position of a pen manually by providing a CPU with a means which calculates the relative position error of the pen as the correction quantity of recording operation according to a recording position which is detected by a photosensor and determined with a pen where no sensor is mounted. CONSTITUTION:This recorder consists of photointerrupters 17 and 18 which are mounted on a carriage 25 and detect the positions of pens 15 and 16, a thermal head 35 which records a scale on recording paper, the photosensor 36 which is provided to either of the pens 15 and 16 and head 36 and detects recording positions by the pens 15 and 16, a CPU 5, etc. The CPU 5 functions for recording operation processing and also calculates the relative position error between the pens and head 35 as the correction quantity of the recording operation as to both pens 15 and 16 according to the recording positions of the pens 15 and 16 at a 0% and a 100% position detected by moving the sensor 36. This value is therefore used as the correction quantity to perform recording, thereby realizing recording after the error is corrected.

Title: Power filter circuit
Inventor: ISHIGURO TAMAHIKO
IPC: H02J3/01
Filed: 1989-02-08
Abstract: PURPOSE:To make it possible to suppress foreign surges invading after the fuse is fused by connecting a backup feeder line where an alarm contact is inserted in series between a power supply section and a control section and by supplying the power to the control section through the backup feeder when the fuse is fused. CONSTITUTION:A backup feeder line 21 is laid through an alarm contact S inserted in series between a power supply section 11 and a control section 13. The backup feeder line 21 keeps on putting the control section 13 in an active state whether a capacitor C is charged or discharged even after a fuse F is fused and on exciting a relay coil 32, by which the alarm contact S remains conducting. On that account, the foreign surges invading after the fuse F is fused are absorbed by the discharge of the capacitor C. The foreign surges invading after the fuse F is fused can thereby be suppressed.

Title: Method and device for selecting fine spherical particle
Inventor: MATSUURA TOSHITAKA
IPC: B07C5/06
Filed: 1988-02-10
Abstract: PURPOSE:To accurately select fine spherical particles which are small in specific gravity by dropping aspherical particles on a particle selection plate while displacing the aspherical particles selectively by a larger quantity in an acceleration direction than the spherical particles. CONSTITUTION:Particles are supplied by a proper amount at a time onto the particle selection plate 2 which has a smooth surface and slants so that the particles are easy to roll. Acceleration in one horizontal direction is applied intermittently in both directions of the selection plate 2. Consequently, a group 3 of particles to be selected receives frictional force from the surface of the selection plate 2 and rolls nearby the upper part of a lock bank 2 on the selection plate 2 with inertial force. The aspherical particles 3B receive larger kinetic energy in the acceleration directions from the surface of the selection plate 2 than the spherical particles 3A and are easily displaced. Consequently, every time the selection plate 2 is applied with the acceleration, the aspherical particles 3B roll downward by gravitation while displaced gradually and greatly in the acceleration direction. The spherical particles 3A is small in displacement quantity in the acceleration direction and roll down along the slanting surface of the selection plate 2. The fine spherical particles are therefore selected with accuracy.

Title: Power failure detecting circuit
Inventor: MATSUMURA NAOYA
IPC: H04M19/08
Filed: 1985-02-18
Abstract: PURPOSE:To detect the power failure of AC power source quickly by monitoring a DC voltage independently by a photocoupler without being influenced by a smoothing circuit provided in an AC/DC convertor. CONSTITUTION:An output voltage of a rectifier circuit 12 is inputted to the diode 14a of a photocoupler 14. On the other hand, an output of the rectifier circuit 12 is connected to a smoothing circuit 13 through a diode 16 to prevent a reverse current. Accordingly, when a commercial power source 2 is in conductive state, the diode section 14a is energized and the transistor section 14b becomes conductive, and a capacitor 152 becomes the state of discharge. An input voltage of a NOT circuit 153 becomes low, and an output voltage of the NOT circuit 153 becomes high. On the other hand, when an output voltage of the NOT circuit 153 changed to low level, a processor 10 judges that the commercial power source 2 is failed and sets gates 41-4n in a signal separating circuit 4 to cut-off state. Consequently, various information transferred from a basic telephone circuit section 3 to a high-function circuit section 5 is cut off immediately.

Title: Detecting amplifier circuit
Inventor: HIRATA MASAKI
IPC: G11C7/06
Filed: 1980-03-10
Abstract: PURPOSE:To increase the sensitivity of a threshold voltage compensation type detecting amplifier, by making an amplifying transistor nonconductive by a charging transistor and even in the input mode and then discharging slowly the common source point. CONSTITUTION:The nodes NA and NB are charged by the clock phiP, and a diode- connection is secured between the amplifying transistors Q1 and Q2 forming an FF via the clock phiT. Then a discharging is carried out down to the threshold voltage of the transistors Q1 and Q2 each. Then the signal is supplied by the clock phi1, and at the same time the common source point NS is charged via the charging transistor Q9. As a result, the transistors Q1 and Q2 become nonconductive, and thus the discharge is not carried out immediately via the transistor Q8. And the transistors Q1 and Q2 are activated gradually by the clock phiS. Accordingly the input voltage is not amplified immediately simultaneously with a signal input. As a result, the variance of the circuit constant can be compensated to realize a threshold voltage compensation type detecting amplifier having a high sensitivity.
