Abstract: PURPOSE:To lighten or remove driver's sleepiness without imposing any burden on a driver by calculating the number of alpha waves, rapid waves and slow waves in driver's brain waves so as to detect a level of the sleepiness and giving various stimuli to the driver according to the level of the sleepiness. CONSTITUTION:Brain waves of a driver are detected by a brain wave detecting means 1 and the detected brain waves are classified by a brain waves classifying unit 2 and also the number of an alpha wave, a rapid wave and a slow wave per unit time is calculated by a calculator 3 according to the classified brain waves. A stimulus unit 5 is controlled by a stimulus control unit 4 according to the calculated result. At this time, the stimulus unit 5 is composed of three kinds of units, a stimulus unit A (tank) 5a, a stimulus unit B (buzzer) 5b and a stimulus unit C (balloon) 5c. That is, driver's sense of smell is stimulated by spraying essence from the tank 5a and driver's sense of hearing is stimulated by ringing the buzzer 5b and driver's sense of touch is stimulated by expanding and shrinking the balloon and making comfortableness to sit worse. Thereby, the driver's sleepiness can be lightened or removed.

Abstract: PURPOSE:To remove a high frequency signal component included in the output signal of a photoelectric converting element string by passing through an analog output signal outputted from an image sensor to a low-pass filter. CONSTITUTION:The output signal outputted from a CCD chip 21 is outputted at the low output impedance by a buffer circuit 111.

Filed: 1987-10-09
Abstract: PURPOSE:To print both front and back covers of a passbook in one time operation by providing a mechanism which is capable of rotating a character pattern by 180 degrees in a print buffer memory. CONSTITUTION:The address of a storage area and the end address b+31 of the work area of a print buffer memory are loaded in pointer registers P and Q. One byte of data pointed by the register Q is loaded in a register A, and shifted one bit to the left, including a carry C. A register B is shifted one bit to the right, including a carry C. This shift operation is repeated eight times, and consequently the register B contains one byte of data resulted from the shifts from bit 7 to bit 0, bit 6 to bit 1,..., bit 0 to bit 7. This byte is stored at the address pointed by the pointer P. The contents of the register Q is checked for whether it points the address (b). If it does not, the register Q is decremented while the register P is incremented, until the register Q points the right address. In this manner, the print buffer memory can store a 180 deg.-rotated character pattern.

The liquid is sent to a fan coil unit 5 by the slurry pump 4 and discharged to a heating load within a heat exchanger. In turn, in case of cooling operation, the non-freezing liquid is cooled with a cold heat, moisture content in the non-freezing liquid is freezed into sherbet form and stored in the thermal accumulating tank 3, sent to the unit 5 with a pump 4 and then heat exchanged with heat in the cooling load.
