Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent skew feed of paper by adjusting the energizing force of each pressure roller to a feed roller or/and the thickness of sheet-like guide piece coming in elastic contact with the periphery of the feed roller, so as to generate such paper feeding force as to offset the deviation of tension in a paper cross direction. SOLUTION: A paper feeder is provided with a feed roller 70 and pressure rollers 71 provided upstream of printing mechanism, lever members 75 for supporting the pressure roller 71, a pair of discharge rollers provided downstream, and the like. Springs 78A-78F are provided to impart energizing force individually to the respective pressure rollers 71 through the lever members 75, and the energizing force is adjusted to offset the deviation of tension according to the deviation of tension in a paper cross direction before and after paper feeding of the paper feeder. The thickness of guide pieces 79A-79F is also adjusted in the same way according to the deviation of tension. Skew feed of paper is thus eliminated.

Title: Semiconductor laser
Inventor: MIZUOCHI HITOSHI
IPC: H01S5/00
Filed: 1992-02-07
Abstract: PURPOSE:To decrease the currents flowing through boundary defects in a semiconductor laser by specifying the carrier concentration in a p-type lower cladding layer so that the p-n junction between a buried layer and its cover layer may be deviated from the recrystallization boundary. CONSTITUTION:A p-type lower cladddinglayer has a carrier concentration of 2X10<18>cm<-3>, while buried current blocking layers 22 and 23 of p-InP have lower concentration than the cladding layer. Since the lower cladding layer 21 has lower resistance than the buried current blocking layers 22 and 23, the number of carriers in the current blocking layers is decreased and the efficiency of carrier injection into an active layer 17 is improved. When the buried layers are grown, autodoping of p-type impurity occurs. Therefore, a p-n junction is formed as indicated by a dotted line, which is deviated from the recrystallization boundary 26, and thus the currents flowing through boundary defects are reduced.

Abstract: PURPOSE:To prevent the alarm sound of a direction indicating device from being drowned by the sound of an acoustic device by providing a sound volume increasing means for increasing the sound volume of the alarm sound at the operated time of the acoustic device mounted to a vehicle. CONSTITUTION:When the main switch 28a of an acoustic device is turned on, a switch 28b interlocked with the main switch 28a is also turned on, so that a current flows to the circuit of a buzzer 22, a volume 26b and the switch 28b. The total resistance value of the lower reaches side (earth side) of the buzzer 22 is thereby reduced, so that the current flowing in the buzzer 22 is increased, and the sound volume of the buzzer 22 is also increased. The alarm sound of the buzzer 22 is thereby prevented from being drowned by the sound of the acoustic device in operation. Moreover, when the volume 26b increases the volume 26a and sound volume of the acoustic device, the sound volume of the buzzer 22 is also increased correspondingly.

Title: Transistor switching circuit
Inventor: HATAKAWA MAMORU
IPC: H03K17/08
Filed: 1980-04-30
Abstract: PURPOSE:To protect a load switching transistor against an overcurrent securely in safety by making the Darlington connection of the transistor so that the base current is supplied by detecting the emitter-collector voltage when an overcurrent flows through the transistor. CONSTITUTION:When load control signal S enough to turn on a rated load is applied to the base of transistor TR1, the base current flows from base power source V1 to TR2 by way of resistance R1, diode D1, and the collector and emitter of TR2. If an overcurrent flows to load L, TR2 does not turn on completely only by the base current enough to turn on the rated load current. When emitter-collector voltage VCE2 of TR2 becomes equal to the sum of base-emitter voltage VBE2 of TR2, emitter- collector voltage VCE1 of TR1, and the forward voltage of diode D2, it does not increase further, flowing the overcurrent. Thus, TR2 is protected against the overcurrent securely in safety.
