Title: Automatic train operating apparatus
Inventor: OMURA MASASHI
IPC: B61L25/02
Filed: 1992-05-19
Abstract: PURPOSE:To prevent a train from overrunning under a normal deceleration control by conducting a home-position stop control based on a premise that a ground point detection is, in the case of a ground point detection error, is executed at a stored ground point. CONSTITUTION:If a ground element P1 is detected in a detecting section, the distance L1 up to next ground element P2 and detecting section lengths a21, a22 of the element P2 are read, and a traveling distance is newly started to be integrated from the ground point of detecting the element P1. Further, a residual traveling distance S1 of a home-position stop control is set. On the other hand, if the element P1 is not detected even at an end of the detecting zone, i.e., the ground point of a distance (L1+a12), it is assumed that the element P1 has been detected by going back by the distance a11. That is, the distance to the next element P2 is set to (L2-a12), and the residual traveling distance of the home-position stop control is set to (S1-a12). Thus, since the home-position stop control is possible, a train can be stopped at the same deceleration as that of the normal home-position stop control without overrunning.

Abstract: PURPOSE:To prevent the occurrence of the fault of images and to reduce power consumption during copying when the temperature of a photosensitive body drum is below an initial set temperature in a waiting state by heating a heater and raising the temperature of the photosensitive body drum until it reaches the initial set temperature. CONSTITUTION:A thermistor detects the temperature of the photosensitive body drum 7 and an initial temperature is determined in an initial temperature set circuit 44 by means of an outside air temperature sensor 45. Both values are compared in a heater control circuit 43. A main processor detects whether the drum 7 is in an image forming state or not. When the compared result of the control circuit 43 shows that the temperature detected by the thermistor 40 is below the initial set temperature, it is decided that the processor 48 is not in the image forming state. The control means 43 heats the heater 41 through a heat circuit 42 so that it reaches the initial set temperature. As a result, the occurrence of the fault of the images is eliminated and the power consumption during copying can be reduced.

Title: Magnetic ink recorder
Inventor: NAMOTO YOSHITERU
IPC: B41J2/17
Filed: 1981-08-12
Abstract: PURPOSE:To effectively construct a supply passage without operating large negative pressure instantaneously to a hole by increasing fluid passage resistance of the supply passage by fluid passage resistance varying means for the prescribed period of time immediately after a supply pump is stopped. CONSTITUTION:Fluid passage resistance varying means 21 is set to the state shown in Fig. 1, magnetic ink 14 is supplied by a supply pump 17 in a direction of an arrow (a), and when the ink passes a hole A, the ink is adhered to the end of a stylus 10 by the attracting force of the stylus 10 to a projecting magnet 12. When the pump 17 is stopped at this time, the ink 14 instantaneously tends to return to the tank 15, but when the means 21 is set to the state shown in Fig. 2 simultaneously upon stoppage, the fluid passage resistance in the supply passage  15 increases, thereby eliminating the delay in the flow of the ink 14. Thus, the  attenuating amplitude is reduced, and a passage to the end of the stylus 10 effectively without exceeding the limit value of the pressure head capable of  enduring at the hole A can be composed. Then, the means 21 is returned to the  original position, and a recording is then performed.

Title: Color conversion adjusting method
Inventor: MURAMOTO YASUHIKO
IPC: G03F3/10
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To exactly adjust color conversion while suppressing density nonuniformity. SOLUTION: When printing out a chart for the control or confirmation of color conversion onto recording paper concerning a color conversion control method for color printer, a checkered pattern alternately arranging white and black squares having one side for 2 to 4 mm like a checker board is printed out at the section of recording paper to become the background of chart. Since white and black squares are mixed almost equally in an area ratio inside any arbitrary background area wider than fixed scale in this checkered pattern, a duty ratio gets almost uniform within a print picture and load applied to a head is reduced. Thus, density nonuniformity is suppressed and exact color conversion can be controlled.

Title: Direct current stabilizing power supply unit
Inventor: GOTOU TERUO
IPC: H04N5/63
Filed: 1979-10-01
Abstract: PURPOSE:To reduce the variation of the horizontal amplitude for the TV set, by adding the voltage generated across the resistance for protecting rectified current to  the reference voltage and then lowering the output voltage in a certain proportion to the increase of the current of the power supply unit which is caused by the increment of the beam current or other factors. CONSTITUTION:One end of the dash preventing resistor R1 connected to the output side of the rectifier D1 is connected in series to the Zener diode D2 for reference voltage of the transistor TR2 for detection of the difference. And the voltage generated across the resistor R1 is added to the reference voltage. And when the current flowing to the power supply unit is increased due to the increment of the beam current of the TV set, the voltage generated across the resistor R1 increases with a reduction secured for the emitter voltage of the TR2. Thus the collector current is increased. Then the base voltage of the TR1 is lowered down, and then the voltage to be supplied to the TV set is reduced in a certain proportion to the increase of the current. Thus the variation can be reduced for the horizontal amplitude.
