Title: Optical character reader
Inventor: ASAMI HIROAKI
IPC: G06V10/98
Filed: 1981-03-31
Abstract: PURPOSE:To improve the working efficiency of the correction for an optical character reader, by deciding whether or not the collation and correction should be carried out according to the number of rejected characters. CONSTITUTION:The character patter train equivalent to a line of a slip which is read out of a photoelectric converting part 1 is cut out to a character pattern with every character through a preprocessing part 3. This cut-out character pattern is recognized at a recognizing part 4. When a character is rejected based on the result of recongnition, a reject code is sent to a control part 6. The number of reject codes equivalent to a page is counted by a counter 62 at the part 6. The count value of the counter 62 is compared with the set value of a register 61. When the count value of the counter is larger than the set value, the collation and correction is carried out. And no collation and correction is carried out when the count value of the counter 62 does not reach the set value. In such way, the time required for the collation and correction is reduced to improve the working efficiency of the correction.

Title: Inverting type optical amplifier
Inventor: NAGANO KATSUMI
IPC: H03F3/08
Filed: 1986-03-06
Abstract: PURPOSE:To realize a stable inverting type amplifier by allowing a photoelectric conversion element to convert the received input light into a photovolatile current and allowing a drive means to drive an electrooptic conversion element by a current inversely proportional to the said photovolatile current. CONSTITUTION:Let an input light be P1, let a reference input light be PREF, then the input lights P1, PREF are converted respectively into photovolatile currents IP2, IP1 by two photodiodes (photoelectric conversion elements) PD2, PD1. An amplifier A amplifies the difference between the photovolatile currents IP1, IP2 to supply the forward current IF of a laser diode (electrooptic conversion element) LD. Thus, the laser diode LD generates a light output P0. A light kP0 proportional to the output light P0 from the laser diode LD is fed back to the photodiode PD2. When the input light P1 is close to the reference input light PREF, the output light P0 is linear as shown in figure. The gradient in this case is (1/k), which represents the amplification factor. The transfer characteristic of the input/output light is represented as the inverting amplification.

Filed: 1979-04-23
Abstract: PURPOSE:To enable low current consumption, by giving the time difference for the output with the inverter circuit constituting the preamplifier circuit and the output circuit taking this output as input. CONSTITUTION:The complementary circuit constituted with the n-channel MISFETQ5 and p-channel MISFETQ6 is the output buffer circuit. This output circuit is driven with the preamplifier circuit.

Title: Tracking error correcting circuit
Inventor: HARADA TOSHIHISA
IPC: G11B7/09
Filed: 1987-03-03
Abstract: PURPOSE:To always obtain the constant amplitude of a tracking error signal by providing a differential amplifier which generates a control signal for controlling the amplification factor of a multiplier by subtracting an output from a sample hold circuit with a reference voltage. CONSTITUTION:The higher the amplification factor of the differential amplifier 1 is, the better it is, so that it is used at more than several tens fold factor. Thus, the variation of the amplitude of the corrected tracking error signal can be decreased. The output 9 from the differential amplifier 1 is increased as the amplitude of the tracking error signal 5 is lowered. Therefore, in the multiplier 2 the coefficient by which the tracking error signal is multiplied increases and the amplitude of the signal inputted in an envelope detector 3 increases, so that the control signal 9 is increased until the output 8 from the sample hold circuit 4 becomes nearly equal to the reference voltage. Thus, the amplitude of the corrected tracking error signal is kept always constant even if the amplitude of the tracking error signal 5 is changed.

IPC: G06F15/177
Filed: 1988-03-02
Abstract: PURPOSE:To assign a task without increasing the load of a general processor or a sub-processor by assigning the task to an optimum sub-processor at high speed by the unified processor when the task to be newly processed occurs. CONSTITUTION:The general processor 1, when a task to be newly processed occurs,outputs the priority level to a communication line 3. Respective sub- processors 21, 22,...,2n calculate the difference between the new priority level and the a value (for example, priority level of task) related to the task during the present execution and send the value of the largest difference and the identification number of the sub-processor onto the communication line 3. The general processor 1 knows the sub-processor to assign the new task by the information to return by the communication line 3. Thus,without increasing the load of the general processor 1 or the sub-processors 21,...,2n, the assignment of the new task can be realized with a simple constitution and at high speed.

Title: Electromagnetic type stylus pressing device of acoustic reproducer having reproduction selecting circuit
Inventor: WATANABE KATSUMI
IPC: G11B3/12
Filed: 1980-04-15
Abstract: PURPOSE:To make a selection type acoustic reproducer simple in construction and compact by eliminating a stopper mechanism in said device. CONSTITUTION:When the pickup of a tone arm 3 reaches the end point of repro- duction on progressing of reproduction operation and approaches to a magnetism sensitive reed switch MSW, a magnet 10 operates, and turns this switch MSW on. As a result, an inhibitor transistor TR5 goes on to inhibit the inflow of the base currents of the transistors TR3, TR4 of a transistor circuit 9 for actuator. Hence, the circuit 9 goes off, and disables an electromagnetic actuator 5, thereby releasing the stylus pressure upon the pickup. The tone arm 3 is reset to the end point of reproduction by a resetting spring. At this time, the switch MSW goes off, but the inhibitor switch is kept turned on by a capacitor C, thereby inhibiting the operation of the actuator 5 on the way of resetting of the tone arm 3.

Abstract: PURPOSE:To enable highly-precise detection of stress by providing a linear body in a transparent plastic isotropic body and by measuring the intensity of a light in the direction of the axial line of the linear body generated by a load applied to the linear body. CONSTITUTION:The linear body 3 having a bending angle of 90 deg. is provided on the surface 2 of the isotropic body 1 made of transparent plastic and a light source 8 is detected in the axial direction of the linear body 3 by a photoelectric transducing element 10.

Abstract: PURPOSE:To eliminate an error by extracting only a steep pulselike defective detection signal by performing irradiation with two kinds of different-wavelength laser beams at a fine interval, and then removing a noise due to slight unevenness by finding a difference between their scattered light signals. CONSTITUTION:A blue laser beam 6 and a red laser beam 7 are illuminated a half-mirror 8 at right angles to each other, and thus the surface of a sample 9 is irradiated with both the beams in parallel at an interval of several mum. Light scattered by the surface of the sample 9 is guided into an integral ball 10 and then passed through a red filter 11 and a blue filter 12 to separate the scattered reflection light, which is converted photoelectrically converted by  photomultipliers 13 and 14. Those two signals are inputted to a differential amplifier 15 to eliminate a noise signal due to unevenness and consequently only a  defective signal remains, thus improving detection precision.
