Title: On-vehicle acoustic apparatus
Inventor: KOYAMA YOSHIHIDE
IPC: G11B31/00
Filed: 1994-11-18
Abstract: PURPOSE: To return an acoustic apparatus to a desired operation without viewing an operation panel since the operation can be returned to the action before setting of an emergency operation state by providing the operation panel with a key and operating this key. CONSTITUTION: An operation mode just before a power source key switch 22 is turned off is, read out of a RAM 9 storing this mode and the apparatus is operated in this mode when this key switch is turned on.

In succession, a reception unit 3 and a sound source changeover switch 6 are set at a traffic information broadcasting receiving state in the ISR reception mode by the storage of a ROM 8. The power source switch is turned off without storing the ISR operation state just before the on turning-on of the key in the RAM 9 when the switch 22 is turned on in this state.  In succession, the operation is not reset to the ISR operation and returns to the state stored in the RAM 9 just before the shift of the ISR operation by turning-on of the power source. As a result, the cancellation of the ISR operation mode is possible if the power source is turned on/off during the ISR operation.

Title: Computer display pointing device control- ler
Inventor: UIRIAMU ARUBAATOSU ABERU JIYUN
IPC: G06F3/0487
Filed: 1990-11-15
Abstract: PURPOSE: To improve the operability of the controller by controlling both moving direction and speed of a display mark on a display in response to a direction detection means and a power detection quantization means. CONSTITUTION: When an operator pushes a key in the direction approximately equal to its desired moving direction, the signals showing the key pushing direction are outputted from the direction detection pads 38 and 46. A microprocessor 19 produces a direction control signal to move a pointer in the designated direction by means of the signals which are outputted when the pads 38 and 46 are touched and pressed. Then the power pierces through a detection pad 70 and is transmitted to the part under the pad 70. Thus the power is applied even on a force detection resistor. Therefore, a display mark can be moved at a high speed in a long distance and can be controlled at a low speed in a short distance respectively. As a result, the operability of the controller is improved.
