Title: Device location display device
Inventor: YASUNAGA KENJI
IPC: H02J9/02
Filed: 2000-12-07
Abstract: PROBLEM TO BE SOLVED: To provide a device location display device that can display location of a device such as a phone even in a dark such as occurrence of a power failure. SOLUTION: Each operation button of a phone 201 employs a phosphor. When the phone 201 is hooked on, an exchange 101 supplies a station power to the phone 201. In this case, since power is supplied between contacts B and E and between contacts C and G in relay switches 211, 212, current flows between the contacts E and G to charge up a capacitor section 214. When an incoming call arrives and the phone 201 is hooked off, the contacts A and E, the contacts B and F and the contacts C and H are closed. The conduction between the contacts A and E causes current resulting from electric charges stored in the capacitor section 214 to be supplied to an LED 216, which is lighted. Since the LED is placed around each operation button, the LED emits light to each button so as to allow the phosphor of each button to store the light.  On the occurrence of a power failure, the stored light lights up each button.

IPC: F02P11/00
Filed: 2000-12-08
Abstract: PROBLEM TO BE SOLVED: To satisfy the ignition performance and part temperature condition required for taking refuge running in the case of abnormal ignition. SOLUTION: This ignition system is provided with a normal time power supply circuit 17 for supplying energy supplied from a battery 16 through an energy coil 13 to the primary side circuit of an ignition coil 11 when the system is normal and an abnormal time power supply circuit 18 for supplying energy from the battery 16 directly to the primary side circuit of the ignition coil 11. An ECU 15 switches a current carrying time signal IGt in the abnormal ignition to a signal with a different pulse duration from a current carrying time signal IGt in the normal ignition, to keep a switching element 25 for ignition driving in the on-state during the time corresponding to the pulse duration of the current carrying time signal IGt.  Thus, in the abnormal ignition, the current carrying time of the primary current of the ignition coil 11 is controlled to satisfy the ignition performance and part temperature condition required for taking refuge running.

Title: Keyboard device
Inventor: TOMITA IWAO
IPC: G10B3/12
Filed: 2000-12-15
Abstract: PROBLEM TO BE SOLVED: To absorb an impact or vibration caused by a hammer arm and to improve the capacity of repeated beating. SOLUTION: An upper limit stopper 19 consists of an elastic part 20 which is provided on a keyboard chassis 1 and is elastically deformed in accordance with a contact force of a hammer arm 3 and a buffer material 21 which is provided for the elastic part 20 and reduces the impact of the hammer arm 3. Consequently, the elastic part 20 is scarcely elastically deformed and the buffer material 21 absorbs the impact and vibration of the hammer arm 3 when a key 2 is depressed with a weak or middle force.  When the key is depressed with a strong force, the elastic part 20 is elastically deformed while the buffer material 21 absorbs the impact and vibration of the hammer arm 3, but the hammer arm 3 is quickly restored because not only the impact or vibration of the hammer arm 3 is surely absorbed but also especially the elastic part 20 gives a repulsive force corresponding to the elastic deformation to the hammer arm 3. Therefore, the impact and vibration of the hammer arm 3 are absorbed and the same key 2 can be repeatedly depressed at a high speed.
