Abstract: A light-emitting device includes: an anode; a cathode; a light-emitting layer between the anode and the cathode; and a hole transport layer between the anode and the light-emitting layer, the hole transport layer containing carbon and a metal oxide in a prescribed, adjusted ratio.

Abstract: A vehicle window regulating apparatus is designed to move a window glass in a door on the side of a passenger seat up and down by operations of a remote contol switch installed on the door on the side of a driver seat. A relay is provided on a power supply line for supplying electric power to a motor in the door on the passenger seat side. This relay and the remote control switch are connected by way of a signal line and is of a diameter smaller than that of the power supply line. With operations on the remote control switch, switching signals are supplied to the relay via the signal line, and the relay is thereby turned on and off so as to supply electric power to the motor via the power supply line, so that the window glass is moved upward or downward.

Abstract: A device for opening and closing a vehicle top by rotations of drive shafts rotatably provided with both right and left sides of the vehicle, comprises two individual motors which actuate the individual drive shafts through speed reduction mechanisms, switching relays which switch the direction of rotation of both said motors respectively, switching relay actuation transistors which individually actuate both the switching relays, top-open and top-close command switches which command the opening and closing of said vehicle top, a switch command determination means which ascertains whether the top-open or top-close command switches are operated, an actuation means which conducts the top opening or closing by actuation of said switching relays via said switching relay actuation transistors on the basis of a signal from the switch command determination means when the top-open or top-close command switches are operated, rotation synchronization sensors which are possessed by at least one of the two motors and gene

Abstract: This concealed wiper system comprises a wiper motor (1) having a mechanism to house the wiper arm in the retracted position by reversing rotation of the wiper motor; an oscillator (50) in which the oscillation frequency is varied by means of a variable resistor (59) installed within the automobile compartment; a wiper actuation switch (3) for wiper actuation selection; a wiper motor-position detector (2) for detecting wiper motor output shaft position; a wiper motor drive circuit (6) for driving the wiper motor; and an intermittent actuation control device employing a microcomputer (5).Intermittent actuation is selected by means of said wiper actuation switch (3), the intermittent pause period is based upon signals from said wiper motor-position detector (2) and signals from said means of oscillation (50), said wiper motor drive circuit (6) is controlled by the microcomputer (5).

Abstract: A concealed wiper system comprises a wiper motor (1) having a mechanism to house a wiper arm in a retracted stop position by means of the reverse rotation of the wiper motor;a wiper actuation switch (3) with output capability which consists of a two-bit selection signal output from the selected switch positon;a wiper motor position detector (2) which detects data on wiper motor output shaft position, said detector output capability consisting of a two bit position signal determined by the position of said output shaft;a control means (4) consisting of a microcomputer which operates based upon said selection signals and position signals, said microcomputer also outputs both normal and reverse rotation signals; anda wiper motor drive circuit (6) which actuates said wiper motor in both normal and reverse rotation by means of signals from said control means.
