Title: Passenger guiding device
Inventor: NAMIKI MASAHITO
IPC: G07B15/00
Filed: 1993-03-25
Abstract: PURPOSE:To safely and surely guide a passenger to the target place by executing guide processing from an automatic ticket examination machine to the entrance to a platform with radio communication between a communication unit for guide inside a station and the communication unit of a passenger ticket after ticket examination. CONSTITUTION:When the passenger gets close to an automatic ticket examination machine, communication between a season ticket and the automatic ticket examination machine 4 is started. When the season ticket is owned by the passenger handicapped in sight, voice information for guiding the passenger to the automatic ticket examination machine 4 is transmitted from the automatic ticket examination machine 4 to the season ticket and at the season ticket, the received information is transmitted through a speaker or earphone to the passenger. When the passenger enters the automatic ticket examination machine 4, ticket examination processing is started. At such a time, the destination of the passenger is discriminated and guide processing is started corresponding to the destination. Namely, the radio communication is repeated between a guide means 7, for which respective guide communication units linked to platforms 3 by destinations are embedded, and the various voice information is transmitted to the passenger while grasping the movement of that passenger.

Title: Detecting circuit of tape running position
Inventor: TSURUBUCHI TETSUO
IPC: G11B27/17
Filed: 1984-04-04
Abstract: PURPOSE:To detect accurately a running distance by inputting pulses proportional to rotations of a supply-side motor and a take-up-side motor and detecting a rotation ratio in accordance with these pulses to calculate winding diameters and detecting a tape position on a basis of them. CONSTITUTION:A direction detecting circuit 11 detects the tape running direction by tack pulses A and B proportional to the rotation of the take-up-side motor which are different in phase by 90 deg.. The tack pulse A and a tack pulse C proportional to the rotation of the supply-side motor are inputted to a rotation ratio detecting circuit 12, and the circuit 12 detects a rotation ratio between both motors on a basis of one tack pulse. A shorter period is effective for the purpose of detecting the accurate rotation ratio. A winding diameter converting circuit 13 converts data of the rotation ratio obtained by the rotation ratio detecting circuit 12 to winding diameters. The winding diameter converting circuit 13 writes winding diameter values for data based on a calculating formula and uses contents of the ROM to perform the conversion. An output circuit 14 detects the absolute position of the tape in accordance with winding diameter values obtained by the winding diameter converting circuit 13 and outputs this position.

Title: Variable pressure once-through boiler
Inventor: MORIO MASARU
IPC: F22B35/00
Filed: 1988-03-23
Abstract: PURPOSE:To provide a variable pressure ONCE-THROUGH boiler device which never falls in non-start-up state caused by a rapid reduction of pressure by a method wherein a circuit for preventing a rapid level reduction of a steam separator drain tank for estimating a reduction in level of a drain tank level and controlling in advance a level adjusting valve is arranged between a drain tank level signal transmitter and a calculator for correcting the tank pressure. CONSTITUTION:A variable pressure ONCE-THROUGH boiler is operated such that as a boiler pressure at an initial starting time of the boiler is low and a boiler furnace fluid temperature approaches its saturation temperature, a phenomenon of expansion of the boiler furnace fluid is generated as an amount of fuel is increased after the boiler is fired. Since a control system of a steam separator drain tank level is provided with a circuit 31 for preventing a rapid reduction of a drain tank level having a differential calculator 32 for controlling in advance a level adjusting valve 6 by estimating a reduction in the drain level, it is possible to estimate a reduction of level before the drain tank level is decreased to a value lower than an upper limit value x2 and to adjust a degree of opening of a level adjusting valve 6. Thus, a rapid reduction of the drain tank level is prevented and BCP trip is also prevented.

IPC: F24F1/00
Filed: 1980-05-22
Abstract: PURPOSE:To reduce the power consumption and to improve the air cleaning performance of the air cleaner by providing a gas detector at a dirty air suction part which detects a gas density and turns off the air conditioner automatically when the detection result is below a set point, though the air conditioner is usually operated by a passenger in the automobile. CONSTITUTION:When the passenger throws manually a key switch 10 and a hand- operated switch 11, a timer 15 starts operation to maintain a normally-open relay 13 to be open and a movable contact 11b to be closed. Accordingly, power is supplied to a motor 8 so that a fan 6 is operated to clean the air in a passenger room. At the same time, the gas detector 3 starts detection of the gas density. When the gas detector comes to be able to perform a stable and accurate detection, the timer 15 starts to put a comparator 11 in operation. With such a construction, when the detection result is below the set point, the hand-operated switch 11 is turned-off, thereby stopping the operation of a purifier. Thus, the power consumption can be minimized and further a normal air cleaning can be obtained constantly.
