Title: Fuel shutoff valve control device
Inventor: IGARASHI KOHEI
IPC: F02M21/02
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To return a shutoff valve to a valve opening state to surely supply fuel by immediately conducting the valve opening control when the pressure of gas fuel becomes designated pressure or less. SOLUTION: While retention control is conducted after the valve opening control, sometimes a shutoff valve is intercepted due to various causes such as instantaneous shutdown or drop of a current value. Even in the case where the shutoff valve is closed due to some reason during the operation of an engine 1, the shutoff valve is surely returned to the valve opening state so as to surely supply fuel to the engine 1. To be concrete, secondary or tertiary gas pressure are monitored by a second pressure sensor 9 and a third pressure sensor 14, and when the shutoff valve (P/R shutoff valve 8a and a delivery shutoff valve 13) is intercepted during the retention control so that the pressure of compressive natural gas is lowered, the valve opening control is conducted to open the shutoff valve and then the transition to the retention control occurs.

Title: Facsimile communication system
Inventor: SAKAGAMI TOMOE
IPC: H04L12/54
Filed: 1993-05-14
Abstract: PURPOSE:To send an automatic answering message to a sender when an incoming call receiver is absent and to enable the sender to perform processing in response. CONSTITUTION:Absence information from a facsimile terminal 1 is registered and stored in an exchange 2 and an informing sentence of the caller from a facsimile terminal 3 is stored in the exchange 2. The exchange 2 informs the caller's terminal 3 of the stored absence information together with an operation selector and the terminal 3 gives a selection instruction for desired operation to the exchange 2. The exchange 2 communicates the stored informing sentence to the terminal 1, sends the informing sentence from the terminal 3 to the terminal 1 immediately, or erases the informing sentence according to the instruction when the absence end date and time in the absence information are reached. Thus, when the incoming call receiver is absent, the sender knows the absence before the incoming call receiver receives the informing sentence and can select a processing procedure to make the facsimile communication service fruitful.
