Filed: 1983-12-26
Abstract: PURPOSE:To prevent wasteful fuel consumption, by forming the titled burner so that post-purge operation is suspended when suspension of combustion action is not confirmed within an established period of time based on a timer device. CONSTITUTION:When a combustion suspension signal is generated, a timer 21 is electrified and post-purge is started.

Simultaneously with the above matter the burner is suspended completely as a disorder lamp 13 is made to light, lighting of the lamp 13 is kept on during a post-purge period of time and contact point 25a is opened after the lapse of the foregoing time.

Title: Ultrasonic pavement sensor
Inventor: SHINOHARA OSAMU
IPC: G01S15/93
Filed: 1992-08-25
Abstract: PURPOSE:To allow acquisition of receiving signal with best SN ratio at all times over the entire speed range from stoppage to normal high speed running by modifying the frequency of ultrasonic transmitting wave gradually to lower as the vehicle speed increases. CONSTITUTION:A vehicle speed deciding circuit l produces a DC voltage proportional to input vehicle speed information and delivers the DC voltage, as a vehicle speed signal, to a transmitting frequency varying circuit 2. The circuit 2 produces a signal having frequency equal to the central frequency fo in the wave receiving band of a transmitter/receiver 6 when the vehicle is stopping whereas produces a signal having frequency lower than the frequency fo by half of the Doppler shift of receiving frequency expected for that vehicle speed after start of running. A transmission burst generating circuit 3 generates a transmission signal burst having frequency variable with the vehicle speed. Since transmission/reception is carried out in the vicinity of central frequency where the sensitivity is high during stoppage and low speed running, a receiving signal having good SN ratio can be obtained.

Title: Production of negative electrode plate for nickel- cadmium storage battery
Inventor: OGURA TAKAO
IPC: H01M4/26
Filed: 1983-12-28
Abstract: PURPOSE:To improve the chemical conversion efficiency of a paste type negative electrode plate by peforming charging and discharging at specific temperatures respectively during the chemical conversion process of the negative electrode plate. CONSTITUTION:Charging during the chemical conversion process of a negative electrode plate is performed at 50-70 deg.C, and discharging is performed at 30- 50 deg.C. The reason why charging is performed at 50-70 deg.C is that hydrogen is generated and the metallic cadmium reduction potential becomes near and the efficiency is deteriorated in case of high-duty charging at a temperature of 50 deg.C or lower. In addition, at 70 deg.C or higher, moisture is evaporated from an alkaline liquid, thus necessitating the alkali density to be controlled. The reason why discharging is performed at 30-50 deg.C is not to enlarge generated cadmium hydroxide, and on the contrary, at a temperature of 20 deg.C or lower the utilization rate during chemical conversion discharging is reduced, partial charging becomes too much, thus causing a phenomenon that the charging voltage is made abnormally high.

Data stored in an address obtained by adding the associative value stored in the operand R1 to the leading address of a table by the combination of ordinary instructions are branched as an address. Consequently, branch processing to a processing routine corresponding to each tag can be rapidly executed.

Title: Internal combustion engine
Inventor: HIRANO MASATOSHI
IPC: F01L7/02
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide an internal combustion engine that prevents pollution and improves fuel economy owing to blowbies limited through appropriate control of the incoming and outgoing of air to and from its combustion chamber. SOLUTION: An air supply pipe 11 connected to a scavenging passage 106 is provided with an air check valve 12. At mixture intake into a crankcase 104, the negative pressure working also in the scavenging passage 106 forces air instead of mixture into the scavenging passage 106. At the subsequent compression of the crankcase 104 by the lowering motion of a piston 105, the check valve 12 forces the air to stagnate continuously inside the scavenging passage 106. At the following scavenging, the air is forced into a combustion chamber 101 in advance of the mixture to thereby force exhaust gas out from the combustion chamber 101. Which system substitutes air for the mixture that are exhausted together with exhaust gas to reduce unburnt mixture blowbies to a large extent.

Abstract: PURPOSE:To easily obtain a switching signal for detecting the synchronization of an intermediate frequency(IF) signal while improving accuracy for the control of the IF by controlling the frequency of a local oscillation frequency signal by using a high-accuracy reference signal, and detecting the synchronization of the IF signal. CONSTITUTION:An RF signal inputted to a tuner input terminal 1 is amplified by a high frequency amplifier circuit 2 and later converted to the IF signal after being mixed with the local oscillation frequency signal from a local oscillation circuit 9 by a mixer circuit 3. The IF is controlled with the high accuracy similar to the accuracy for the crystal oscillator of an oscillation circuit 17. On the other hand, the synchronization of the IF signal is detected in a video detection circuit 6 by using the switching signal for the reference signal from a reference signal oscillation circuit 12, and the signal is outputted from an output terminal 18. Thus, since the reference signal for controlling the IF is used as the switching signal for detecting the synchronization of the IF signal, the switching signal for synchronizing detection can be easily obtained.
