IPC: H01L29/788
Filed: 1989-04-12
Abstract: PURPOSE:To reduce number of components by connecting the source of a P- channel floating gate structure MOS TR to a high level power supply and using an N-channel floating gate structure MOS TR to inject electrons to the floating gate. CONSTITUTION:A write signal inverse of WR goes to a low level at normal operation, MOS TRs 5, 6 are turned off and nodes N1, N3 are separated from a write circuit 4a. A voltage 5V is applied to the drain of a MOS TR3 from a power terminal AV. The signal inverse of WR goes to a low level at the time of writing, a voltage 12V is applied to the terminal AV to supply the power supply of 12V to the nodes N1, N2, and N3. Furthermore, the input terminal and the output terminal are opened. As a result, electrons are injected to the floating gate by the injection of hot electrons due to the channel current in the N-channel floating gate structure MOS TR2. Thus, the power consumption is suppressed.

Title: Control circuit of constant speed travel device for vehicle
Inventor: KURIHARA KATSUMITSU
IPC: B60W30/00
Filed: 1987-04-16
Abstract: PURPOSE:To prevent a dead-short condition among transistors in a drive circuit by making transistors non-alive in an acceleration drive circuit for an actuator, depending upon abnormal output from a watch dog timer circuit, when a control means becomes uncontrollable. CONSTITUTION:At the time of constant speed travel, output signals from output terminals CT3 to CT6 are sometimes not determined when CPU 7 is abnormal. And when an ON-signal is outputted concurrently from the terminals CT3 and CT6, transistors Q3 and Q6 concurrently become alive, thereby causing a dead- short state. In this abnormal state, a transistor Q11 turns ON and a magnet clutch 22 turns OFF. As a result, not only an actuator turns into a non-drive state, but also transistors Q4 and Q7 for an acceleration drive circuit turn OFF, thereby preventing a flow of dead-short currents between the transistors Q3 and Q6, and Q4 and Q5.

IPC: G11B27/024
Filed: 1994-05-06
Abstract: PURPOSE:To facilitate editing operations without using any editing machine by using two VTRs of which one controls the operation of the other. CONSTITUTION:The output signals of the reproducing-side VTR 1 inputted from an input terminal 10 is led to the picture recording circuit 12 of the recording-side VTR 2 to be inputted into a decoder 11. The decoder 11 extracts the information code superposed on the output signals of the reproducing-side VTR 1 to output it to a control circuit 13 and outputs the video signals from which the information code is extracted to an encoder 14. The control circuit 13 controls the recording-side VTR 2 itself based on the extracted information code 14 and outputs the information code to be transmitted to the reproducing- side VTR 1 to the encoder 14. The encoder 14 superposes the information code outputted from the control circuit 13 on the video signals outputted from the decoder 11 to output them to the reproducing-side VTR 1 via an output terminal 15. Then it becomes possible to cause one video apparatus to control the other video apparatus and editing work is made easy.

Title: Exhaust gas re-circulating system
Inventor: KOHAMA TOKIO
IPC: F02M25/07
Filed: 1978-08-02
Abstract: PURPOSE: To reduce amount of NOX discharged from engine, by re-circulating an appropriate amount of exhaust gas correctly in accordance with the operating condition of engine.  
     CONSTITUTION: Exhaust gas is discharged from engine 1 to exhaust pipe 5, whereby exhaust pressure Pe is developed in the exhaust pipe 5 whereas a pressure P s  lower than the exhaust pressure Pe is developed in a exhaust pressure chamber 9. This pressure P s  is transmitted to pressure chamber 23 of pressure regulating valve 20, and when it becomes greater than the compensating pressure in compensating pressure chamber 22, diaphragm 21 is shifted upward so that top of branch pipe 26 is closed by valve body 25. Resultantly, intake pressure in intake pipe 4 is transmitted to pressure chamber 14 of EGR control valve 10. On the other hand, when pressure P s  becomes lower than the compensating pressure in chamber 22, valve 25 is opened so that intake pressure in intake pipe 4 is increased since it is added with said compensating pressure. The intake pressure thus increased is transmitted to pressure chamber 14. Here, compensating pressure in chamber 22 is controlled by pressure compensating unit 30 and control circuit 40.
