Title: Laser recorder
Inventor: SAKAI YUKIO
IPC: H04N1/04
Filed: 1983-12-03
Abstract: PURPOSE:To decrease jitter by detecting the luminous intensity of scanning laser light just before the laser beam is incident to a synchronism detector so as to make the intensity of laser light constant thereby making a detection signal level of the synchronism detector constant at all times. CONSTITUTION:The luminous intensity signal of laser light detected by the luminous intensity detector 14 ahead the synchronism detector 13 is amplified by a signal amplifier 15 and controls the semiconductor laser 1 to attain a prescribed beam by using a control timing generating circuit 16 and a luminous intensity control circuit 17 including a sample and hold circuit. When a scanning laser light is irradiated to the detector 14, a luminous intensity output signal 18 and a luminous intensity control timing signal 19 are generated from the control timing generating circuit 16 via the signal amplifier 15. Then feedback control is applied to bring the luminous intensity output signal to a reference level Vs during this period thereby controlling a bias voltage of a drive circuit 10.

Moreover, the time-metered offset amount during the foregoing detecting systems based on the metered value, that is, the temporal offset amount during the mean value of the foregoing metered values in the left and right detecting systems and the output timing of the reference signal in the reference state that is decided in the state of design or experimentally is calculated. In the positioning processing to be performed hereafter, the time-metered value of the alignment detecting signal is corrected on the basis of this offset amount.

Title: Apparatus for measuring luminance
Inventor: HORII SHIGERU
IPC: G01J1/42
Filed: 1984-10-31
Abstract: PURPOSE:To make it possible to accurately measure the luminance value of an object to be measured, by measuring only the scattering light in an objective lens by a light receiver and calculating the luminance of the objective lens by a luminance converting part while subtracting luminance from measured luminance by a subtraction circuit. CONSTITUTION:The output of a second light receiver 8 is converted to a voltage signal by a second amplifier 11 and the output of this amplifier 11 is sent to a luminance converting part 13. The luminance coefficient generation part 13b of the luminance converting part 13 generates proportional constant for converting the output value of the second light receiver 8 to the luminance generating on a first light receiver 10. Then, the signal from the generation part 13b is multiplied by the output of the amplifier 11 to output SIGMAEdn. SIGMAEdn shows the luminance value incident to the light receiver 10. Next, a luminance signal is subtracted from the output from an amplifier 12, that is, the luminance signal of a luminance measuring system by a subtraction circuit 14. The output of the amplifier 12 is the added value of the luminance real value LT of an object to be measured and a luminance value LB while the output of the converting part is the luminance value LB and, therefore, the output of the subtraction circuit 14 shows the real value LT of the luminance of the object to be measured.

Abstract: PURPOSE:To decrease the internal resistance of an oxygen sensor and to prevent the exfoliation thereof by increasing the area of a reference electrode embedded into the base body of a sensor and to increase the strength of the sensor by decreasing the width of a gap for introduction of a reference material. CONSTITUTION:The plane shape of the reference electrode 6 of the sensor element 1 constituted of a sensor part 20 and a heater part 30, etc. is made into a recessed shape by a notch 6a coinciding approximately with the peripheral edge shape of the gap 7 provided so as to be sandwiched approximately thoroughly between middle and lower solid electrolyte plates 3 and 4. A measuring electrode 5 has the plane shape formed approximately the same as the plane shape of the electrode 6 and is so disposed as to face thoroughly the electrode 6 via the upper and middle solid electrolytes 2 and 3. The width of the gap 7 is decreased by embedding the electrode 6 into said gap, by which the strength of the element 1 is increased and the exfoliation of the electrode 6 is prevented. The area of the electrode 6 is increased so that measuring electrode 5 and the electrode 6 face each other at the area expanded to the same size. The decrease in the internal resistance is thus made possible.

Title: Bar code reader
Inventor: KIKUTA YUKIO
IPC: G06K7/10
Filed: 1986-09-30
Abstract: PURPOSE:To extremely reduce power consumption and to extend the life of a power supply by controlling ON/OFF of a light emitting element during a scanning period. CONSTITUTION:During the scanning period, the light emitting element is turned on and off an a detecting signal from a light detecting means is held in synchronism with the lighting period of the light emitting element. At the time of scanning, the internal resistance of a sensor 14 is changed in accordance with the timing of an LED driving pulse and the color of a bar code 13 and the change appears as the level difference of the potential of a signal on a point A. Namely, when the black part of a bar code 13 is scanned even when the LED driving pulse is in the 'L' period (off of the LED 11) or in the 'H' period (on of the LED 11), no light is inputted to the sensor 14, so that impedance is increased, current does not almost flow into the sensor 14 and the potential of the point A is increased. When the white part of the bar code 13 is scanned during the 'H' period (on of the LED 11) of the driving pulse, light is inputted to the sensor 14, the impedance is reduced and the potential of the point A is also reduced.
