Title: Bar code reader
Inventor: MAKINO SHINGO
IPC: G06K7/10
Filed: 1983-05-13
Abstract: PURPOSE:To improve the sensitivity of a bar code reader by incorporating light emitting output control increasing/decreasing the optical output of an LED so that incident light to a photodetecting element is fixed from the output change of the photodetecting element in the output side of the photodetecting element. CONSTITUTION:A light emitting diode and a phototransistor TR are used for the LED2 and the photodetecting element 3 respectively. A light emission output control circuit 10 reduces its output voltage when the incident light of a TR3 is increased, and increases its output voltage when the incident light to the TR3 is decreased. The circuit 10 is constituted by a TR13 as a dimming element of which base is connected to the output end of an amplifier 11, collector is connected to a DC power supply 12 and emitter is directly coupled with the LED2. The TR13 controls current flowing into the LED2 linearly in proportion to the increasing/decreasing change of the base voltage in a range increasing external incident light or reducing the incident light due to light emission leakage. Thus, the incident light to the photodetecting element 3 is prevented from influence due to the increase/decrease of the whole level and the sensitivity of the bar code reader is improved.

Abstract: PURPOSE:To reduce the quantity of generated gas, to weld to prescribed weld penetration depth, and to improve a quality of a weld, by irradiating an electronic beam repeatedly in order onto the surface of a thick plate, and performing rewelding. CONSTITUTION:A welding material 3 is melted by an electronic beam 5 and is welded. In this case, a welding bead 6a is formed so that the quantity of metallic vapor of the welding bead and the quantity of evaporation of the quantity of discharged gas do not exceed the displacement of a vacuum pump 2 due to the quantity of a contained gas component of the welding material 3. Subsequently, a wedling bead 6b of the second layer is formed, but since gas has been discharged in the first layer bead 6a, the quantity of a gas contained component is small, and even if it is melted in the same bead shape, the quantity of evaporation becomes small, the welding condition is all the same, the weld penetration depth is increased, the quantity of evaporation becomes same as the first layer, and its welding is executed. Subsequently, a wedling bead 6c of the third layer is also welded to prescribed thickness in the same way by reducing the quantity of contained gas by remelting in order, and increasing the weld penetration depth by that portion.

Abstract: PURPOSE:To reduce the consumption time of a battery, by actuating an electrical closed circuit consisting of a potentiometer working in coupling to water pressure gauge and a battery only for the necessary time and closing the circuit when not in use. CONSTITUTION:The signal fa sent from a reference signal oscillator 3 is gated through a gate circuit 2 and the gate pulse supplied from the 1st gate pulse generator 1, and a wave transmitter To is excited by a power amplifier 5 via a buffer amplifier 4. On the other hand, the gate pulse of the generator 1 is applied to a pulse delaying circuit 20. The delay time of the circuit 20 is decided by the resistance value of a delay extent control resistor 23 interlocking the mobile bar of a water pressure gauge 13 and then supplied to the 2nd gate pulse generator 21 in the form of a pulse duration after lapse of a necessary time. With this pulse, the output of the generator 21 obtains the signal, and this signal controls a switching transistor 22. Thus voltage information (e) is generated at a potentiometer 14 only for the time corresponding to the pulse duration of signal.

Title: Current mirror circuit
Inventor: UEKI ISAMU
IPC: H03F3/34
Filed: 1984-04-27
Abstract: PURPOSE:To reduce an error in current mirror ratio and to lower an input voltage by operating a level shifting transistor (TR) through a TR for current direction inversion with a current which flows through a TR for current amplification factor compensation and generating the reference potential of a buffer TR, and eliminating the influence of an amplification factor and early effect. CONSTITUTION:Darlington-connected TRs QB21 and QC21, QB22 and QC22...QB2N and QC2N as buffer TRs have bases connected to the collector of the TRQD2 for current direction inversion and the cathode of the level shifting diode D2, emitters connected to collectors of output-side TRs Q21, Q22...Q2N for a current mirror, and collectors connected to output terminals TO1, TO2...TON. Therefore, this current mirror circuit operates when an input voltage is higher than VBEQA1 (base-emitter voltage) of the TRQA1 for current amplification factor compensation), and base voltages of the TRs QB21, QB22...QB2N are determined following up the input current, so the early effect of the output-side TRs for the current mirror is reduced without narrowing down an input current range.

Title: Dot printer
Inventor: KURITA TOSHIAKI
IPC: B41J2/30
Filed: 1988-04-08
Abstract: PURPOSE:To control fatigue to within specified limits by providing a printing head inactivation means for determining a degree of fatigue at a time when printing of a signal line is completed based on a prescribed printing duration required for printing a single line using the total number of dots of a single line and an actual printing duration and setting a printing head inactivation duration in proportion to the degree of fatigue before the start of next printing. CONSTITUTION:Prescribed printing time required for printing a single line of dot data to be printed next is calculated by a calculation means using the total number of dots for said single line of dot data and a printing head constant. After this, the prescribed printing time is decremented using a counter of degree of fatigue, and if an actual printing time is shorter than the prescribed printing time when a print output action based on an actual single line of dot data is completed, the start of printing a next single line of dot data is delayed by a printing head inactivation means H until the prescribed printing time is reached. That is, a printing head C is inactivated until its degree of fatigue becomes 0.
