Title: Optical bistable element
Inventor: KIMURA HIROSHI
IPC: G02F3/02
Filed: 1989-06-08
Abstract: PURPOSE:To operate an element with a low power consumption by using a multiple quantum well MQW layer as the refractive index varying part and making light incident on this layer and positively feeding back the power of this input light. CONSTITUTION:When an electric field is perpendicularly applied to the well face of a MQW structure, the refractive index is reduced, and the extent of this reduction is larger according as the intensity of the applied electric field is higher, and the reflection power is larger according as the intensity of the electric field applied to the MQW structure is higher. Incident light Pin is made incident on an (i) layer of a pin structure, namely, a MQW layer 2, and light Prf reflected by the refractive index varying part under an electric field applying electrode 3 is guided to a photo diode 4 by a waveguide. The light Prf is converted into a current proportional to this light by the photo diode 4 and is converted into a voltage by a resistance 5, and this voltage is reflected on the electric field applying electrode 3, and therefore, it is positively fed back to the reflection power Prf. Since the power of the input light Pin is positively fed back, the element is operated with a low power consumption.

Title: Automobile telephone system
Inventor: NAGOSHI SUEO
IPC: H04W76/02
Filed: 1991-06-18
Abstract: PURPOSE:To improve the safety of driving by stopping a function of a handset for a driver's seat during driving so as to prevent one-hand drive for the use of the handset for driving. CONSTITUTION:Upon the detection of a call, an automobile telephone set 1 sends a call level signal to an outgoing serial signal line 11 and informs it to a hand-free device 2 and a handset control circuit 5. On the other hand, a drive detection circuit 4 judges whether the vehicle is in driving or at a stop based on a signal from a car speed sensor and sends the result to the handset control circuit 5. The handset control circuit 5 receives it to turn off its internal switch in the case of driving and to turn on the internal switch in the case of stopping. Since the function of the handset 3 for driver's seat is stopped automatically during driving, the driver cannot use the handset 3 and one hand drive for the use of the handset is prevented.

Title: Power supply voltage detector
Inventor: TATSUMI TAKU
IPC: G06F1/28
Filed: 1994-06-28
Abstract: PURPOSE:To detect low battery accurately before starting a system by detecting the battery upon application at a pseudo load and deciding whether the system can be operated or not depending on the digital value thereof. CONSTITUTION:Upon detecting the turn OFF operation of a power switch 8, a power supply control section 7 requests a main block 1 to execute a processing required for turn OFF operation. A control section 7 turns switches 11, 12 OFF to interrupt the power supply depending on a request from the block 1 containing required information in a RAM 4. When the switch 8 is turned OFF again, the block 1 detects the turn OFF operation and turns a switch 13 ON to connect a load resistance R1 with a battery 10. When the power supply voltage is settled after abrupt variation of the load capacity, the battery voltage is measured through A/D conversion 15. The control section 7 controls the operation and when the digital value of battery voltage is lower than a programmed low battery level, the switch 11 is not turned ON but the machine is inhibited to start. Otherwise, a decision is made that the system is operable.
