Title: Magnetic head driving device
Inventor: MARUYAMA TAKAO
IPC: G11B5/09
Filed: 1991-04-15
Abstract: PURPOSE:To stabilize a reproducing operation by making the generating direction of the final recording magnetic field of a head constant and coincident with the magnetizing direction of an adjacent soft magnetic film when a recording operation is shifted to a reproducing operation. CONSTITUTION:Recording data (a) from an encoder 1 are inputted to a recording bit addition circuit 2 and an FF7, and the FF7 identifies whether the total number of the recording bits of the recording data (a) is an odd or even number and transmits an odd or even deciding signal (b) to the circuit 2. The circuit 2 determines whether or not a pulse is added corresponding to the signal (b). The output signal (d) of the circuit 2 is converted by an FF3 so that 1 data bit can be the inversion of recording current (f) to be supplied from a recording amplifier 4 to a recording head 5. Therefore, the current (f) always allows the current to be inversed even number of times. When the direction of the recording magnetic field is determined with respect to an MR element in a composite head 5 and when the recording operation of the composite head is shifted to the reproducing operation, the generating direction of the final recording magnetic field can be made constant and coincident with the magnetizing direction of the adjacent soft magnetic film.

Title: Character generator circuit
Inventor: IYONO EIICHI
IPC: H04N5/445
Filed: 1993-05-10
Abstract: PURPOSE:To set up the number of scanning lines to be used for the display of a space part between lines for displaying a character correspondingly to the number of scanning lines displayed on a screen. CONSTITUTION:A line interval computing circuit 32 divides the number of scanning lines indicating the data p1 of the number of remaining scanning lines by 17 and a number removing the residual from the divided result is supplied to a character height setting circuit 31 as the data q1 of the number of scanning lines for a line interval. The circuit 31 sets up the display area of a character based upon both the data q1 of the number of scanning line of interval from the circuit 32 and set character height. Consequently the number of scanning lines to be used for the display of a space part between lines displaying the character can be set up correspondingly to the number of scanning lines displayed on the screen.

IPC: G03G15/04
Filed: 1983-06-17
Abstract: PURPOSE:To prevent the drop of an exposure quantity by using a recessed form diffusion surface reflector for an illuminating system, scattering the radiant light of a light source, averaging it, detecting only its diffusion light quantity, and controlling a light quantity of the light source so that it always holds an optimum value. CONSTITUTION:A radiant light from a lamp 1 is reflected irregularly by a reflecting surface of a diffusion surface reflector 2 and averaged. The lamp 1 is positioned in the vicinity of the bottom surface of the reflector 2, and the greater part of a light for irradiating the scanning part of an original 7 is a diffused light arriving from an opening part 2a and a reflector 3. The direct light which is made incident to the vicinity of an opening part 4a of a light detecting hole 4 does not reach an optical sensor 5 either because the wall surface is painted in black, and the magnitude of a detecting light is proportional to the average value of intensity of illumination of an original surface. The output of the optical sensor 5 is inputted to a controlling circuit 10, brought to voltage conversion, and thereafter, compared with the reference voltage. In accordance with its difference, a phase control type power source 14 is driven and the voltage of the lamp 1 is controlled, by which an irradiating light quantity is held at a constant value.

Title: Forced-circulation foaming bath
Inventor: NAKAMURA KAZUHARU
IPC: F24H9/00
Filed: 1985-05-21
Abstract: PURPOSE:To make practical use of a vibrating bath and a forced circulation device for a bath at low cost by using a pump obtaining a high-speed water flow in combination with a pump for a forced circulation. CONSTITUTION:The discharge pressure obtained by a pump 9 varies depending upon the rotational speed and easiness of water flow. When an opening and closing valve 12 is opened, a flowpath resistance does not almost occur and the flowpath resistance of a water ejection nozzle 10 at that time is extremely large so that water does not almost flow toward the water ejection nozzle 10 and a volute air quantity is extremely slight. Almost no difference in the performance is found between that time and the time when the flowpath is closed. Further, when an opening and closing valve is closed, water pressurized by the pump 7 entirely passes through the water ejection nozzle 10 having a large flowpath resistance, and the water pressure involving and sucking-up air at the minimum water amount and with a good efficiency can be easily obtained by increasing the rotational speed of the motor of the pump 7. Variation of the rotational speed as described above is possible by varying a voltage supplied, in this case, it is preferable that a DC motor which is not almost affected by a power source frequency.
