Patent JP-S5661101-A (JP)
Title: Magnetic recording medium
Inventor: YOKOYAMA KOUKI
IPC: C09D5/23
Filed: 1979-10-24
Abstract: PURPOSE:To obtain the flexible recording medium which is suitable for high density recording by substituting Co by a part of Fe in hexagonal crystal ferrite which contains a specified element A and is expressed by AFe12O10, and employing fine magnetic particles whose C axis is vertical to the plane. CONSTITUTION:As the magnetic powder forming a magnetic recording layer, is employed the particles of Co substituted hexagonal crystal ferrite or Co substituted hexagonal crystal ferrite which is substituted by other ions for compensating the number of valancy. For example, a specified element A is Ba, Sr, Ca, or Pb; and M is V, Nb, Sb, or Ta; and X=0.5-1.1: Then, we obtain AFe12-xCoxO10-xFex, AFe12-3/2xCoxM1/2xO10, and the like. If x<0.5, the vertical magnetization is not sufficient. If x>1.1, the magnetic recording is difficult. If the diameter of the fine particles of ferrite is less than 0.01mu, ferromagnetism is not expressed; and if it is more than 0.3mu, the high-density vertical magnetization cannot be implemented. The 10-40pts.wt. of phenol resin and the like, 0.5-20pts.wt. fatty acid, and 200pts.wt. of solvent are added to 100pts.wt. of the fine particles. Then, they are blended, rolled, dried; and the work is finished.

Title: Toner recovering device
Inventor: TORII TOORU
IPC: G03G21/10
Filed: 1983-07-26
Abstract: PURPOSE:To enable use of an inexpensive meterial such as a vinyl bag as a toner housing part by making the pressure on the outside of the toner housing part lower than the pressure in a cyclone. CONSTITUTION:The pressure on the suction side of a fan 12 is lower than the pressure in a cyclone 9 on account of the pressure drop in a filter 11 and therefore the pressure in a low pressure device 14 is lower than the pressure in the cyclone 9. Therefore a vinyl bag 13 does not contract and the toner recovered by the cyclone 9 is reserved in the bag 13.

Title: Centerless grinder
Inventor: TSUKAMOTO NOBUO
IPC: B24B5/30
Filed: 1982-08-05
Abstract: PURPOSE:To enable machining of favorable cylindricalness, by a method wherein a work to be ground is made to transfer in an axis direction of a rotary grinding wheel and a regulating wheel, an outlet guide on a regulating wheel side affecting finish cylindricalness mostly is eliminated and the regulating wheel is made to possess that function. CONSTITUTION:A protrusion 14 in a transfering direction is formed and made rotatable by making a regulating wheel 2 protrude longer than a sphere constituted with a rotary grinding wheel 1 and the regulating wheel 2 and confronting with the grinding wheel 1 by a length L1 which is longer than a length l1 of a work 3. Guides 12 and 13 on an entrance side and a wheel 1 side guide 5 on an outlet side are components taking charge of a function of a regulating wheel side guide on the outlet side having the most important effect upon finish cylindricalness by an L1 part of the regulating wheel 2. With this construction, operation for obtaining accuracy (cylindricalness) by a variation of the diameter of the work 3 and dressing by the regulating wheel 2 is simplified. Thus, machining of favorable cylindricalness is made possible.

Title: Radio selective calling receiver with notice holding function and radio selective calling reception method
Inventor: OTSUKI MICHIHITO
IPC: H04W84/02
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in the reception sensitivity, to reduce errors in received data and to suppress a momentary increase in current consumption. SOLUTION: A data segmentation section 3 samples a demodulation signal (b) and a control section (reception control section) 5 outputs a display signal or a ring tone signal (e) or the like to a notice means 8 after awaiting it that no succeeding frame is in existence in itself in response to an output of a reception from discrimination section 6 when received receiver data (c) have a call number of its own device based on an output (d) from an address collation section 4. Thus, a notice operation in the midst of receiving its own frame is prevented when its own address is received and then the reception is conducted in stable reception state.

Title: Magnetic disk device
Inventor: TAMAMUSHI SEIICHIROU
IPC: G11B5/09
Filed: 1984-07-02
Abstract: PURPOSE:To prevent the generation of a data error due to the off-track of temperature by selecting a core that is most suitably opposite to a data zone out of those cores of a data head based on the detected output of a temperature sensor. CONSTITUTION:Cores 23a-23e are set to a data head 23 with shifts given in the width direction of a data zone 10 respectively. The ambient temperature of the head 23 is detected by a temperature sensor 24. The data are recorded to the zone 10 via the center core 23c. Then the head 23 produces the off-track of temperature in case the ambient temperature has a change after a certain period of time has passed. Thus a core selection control circuit 26 reads the off-track amount out of a ROM25 according to the ambient temperature detected by the sensor 24. A core selection circuit 27 selects the core 23a according to said off- grack amount. Then, the recording/reproduction is carried out by the core 23a.

Title: Recording and recording device
Inventor: YAMAGUCHI TAKEO
IPC: B41M5/26
Filed: 1991-05-13
Abstract: PURPOSE:To make possible the formation of an area for recorded data which can be deleted(reversible) using a deletion light and an area for recorded data which cannot be deleted(irreversible) on a single recording medium by using a polymer liquid crystal for a recording layer. CONSTITUTION:A recording medium consists of a recording layer 2 of polymer liquid crystal, an orientation layer 3 where said liquid crystal is oriented, and a light/heat conversion layer 4, laminated and molded on a substrate 1. If a light absorbent such as color is added to the recording layer 2 or the orientation layer 3, the light/heat conversion layer 4 can be dispensed with. A recording light beam is absorbed by the light/heat conversion layer 4 and the molecular orientation state of a part in a thickness direction of the recording layer 2 is allowed to change using a heat amount generated in response to the absorption, or a change in the phase is allowed to take place to record data reversibly. Alternatively, the molecular orientation state of the entire part in a thickness direction of the recording layer is allowed to change or its phasic change is permitted to change, to record data irreversibly. The projected energy of the recording light beam can be controller by changing the scanning speed of the recording light beam. Both reversible and irreversible information can be entered in the single recording medium.

A control circuit 7 is provided to output alternately a coarse adjustment signal and a fine adjustment signal from the temperature compensation output. Moreover, a reset signal is sent to rewrite new data alternately to the 1st and 2nd D/A conversion sections. A compensation signal converted by each D/A conversion section is given across a varactor diode. Each D/A conversion section is incorporated with a holding circuit and a latch circuit and even when coarse and fine adjustment signals are rewritten alternately, since the preceding data is held, no large frequency fluctuation is caused.

When the power supply from the main body side becomes impossible due to power interruption, etc., the power supply is switched to the power supply from a line. Namely, because a power source 32 does not operate at the time of the power interruption, the operation of the circuit of a secondary side of a line is stopped and only the speech for which a handset 29 is used can be performed. When an off-hook is performed for the handset 29 in, for instance, a transmitting operation, a hook switch 14 is switched to the side of a polarity matching diode 16.  At this time, power is supplied from a line to the speaker circuit 17 and the dial circuit 18 through the diode 26.
