Title: Domestic simplified telephone exchange
Inventor: KOMODA YOSHIYUKI
IPC: H04M1/72
Filed: 1990-11-27
Abstract: PURPOSE:To use an automatic answering telephone set even to a doorphone by responding the automatic answering telephone set according to a pseudo incoming signal in the case of a call from the doorphone and stopping the automatic answering telephone set according to a pseudo busy tone when speaking is finished. CONSTITUTION:When there is a call from the doorphone, it is detected by a detecting circuit 14 and outputted to a control circuit 11. The circuit 11 controls a pseudo incoming signal generating circuit and transmits the pseudo signal to a telephone set C. At such a time, when the user is absent, the automatic answering telephone set automatically makes a response while responding to the signal, a speech path is formed similarly to the response of the user, and the automatic answering telephone set is operated. After the lapse of recording time set in advance, the circuit 11 disconnects the doorphone speech path, transmits the busy tone from a signal tone generating circuit 20 to the automatic answering telephone set and automatically stops the recording state. Thus, the automatic answering telephone function can be used even to the doorphone as well.

Title: Notch signal output circuit
Inventor: NAGASE NORIO
IPC: G05D3/12
Filed: 1987-12-25
Abstract: PURPOSE:To output an accurate notch signal with a small hardware by dividing a notch signal output timing from an ideal position, a deviation quantity and a speed and executing the forecasting control to apply the speed correction. CONSTITUTION:An ideal speed curve lv1 is generated by a command from an MPU 4, following-up is executed to the ideal position curve lx1, the speed and position become like curves lv2 and lx2 due to the delay of the servo system actually, and a position deviation quantity DELTAX is generated. In respective real times t1, t2, t3,... during the positioning action for a period T, the MPU 4 obtains the ideal position of the real time, reads a deviation quantity DELTAX from a deviation counter 2, subtracts the deviation quantity DELTAX from the ideal position and obtains the actual present position. By dividing the difference between the present position and notch signal output position by the actual speed, a notch output timing DELTAT is obtained, and the DELTAT is set to a timer 3. The MPU 4 outputs the notch signal in the interruption processing program with the time-up signal from the timer 3 as the interrupting signal.

Title: Fuel injector for inter-cylinder direct injection type spark ignition internal combustion engine
Inventor: SHIBATA KENSHIROU
IPC: F02B75/12
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To avoid the worst condition that starting is disabled by executing fuel injection only within a crank angle zone in which detected fuel pressure is at inter-cylinder pressure or more, and inhibiting the fuel injection in the crank angle zone except for the above. SOLUTION: A high pressure fuel pump 15 is driven by the crankshaft or camshaft of an engine so that a pump rotational speed is low and discharge pressure is also low when an engine speed is low. A fuel pressure sensor 21 is attached as fuel pressure detecting means. In the case that fuel pressure applied to a fuel injection valve 9 is lower than inter-cylinder pressure obtained by means such as referring to a table against a sensor or a crank angle, gas in an engine cylinder makes reverse flow into the fuel injection valve 9 so that bubbles are generated in the fuel injection valve 9 and a piping, therefore, there is possibility that fuel may not be injected correctly. Accordingly, fuel can be ejected only within a crank angle zone in which fuel pressure > inter- cylinder pressure.  Such a problem may easily occur, especially under a state that fuel pressure is low such as at the time of engine starting, and a period for injecting a necessary enough fuel is extended.
