Title: Ignitor
Inventor: NAKAO SATOSHI
IPC: F02P3/05
Filed: 1978-05-23
Abstract: PURPOSE:To enable a most suitable ignition timing without being influenced by unevenness of an input signal, by controlling a charging and discharging circuit according to an input signal of an output switch circuit. CONSTITUTION:When an output of a signal generator 1 is more than a set voltage of a comparison circuit 21, a transistor 25 turns on and a condenser 20 discharges. While a switch 58 is closed or for the duration from opening of the switch 58 to discharge of a condenser 60, transistors 15 and 18 turn on and a condenser 20 charges. The higher a rotative speed is, the more rapidly the charging is performed. When a charging voltage of the condenser 20 exceeds the set voltage, an output of a comparison circuit 26 is reversed and supplied to an or circuit 31, and an electric current is flown to an ignition coil 4 after turning on a transistor 5 through an output switch circuit 6. This condition continues until a pulse at a (b) point falls. Since a charging level of the condenser 20 is proportional to the rotative speed, an off time of a transitor 5 can be controlled.

Abstract: PURPOSE:To provide a method for accurately measuring the receiving level of a received melted plastic in a raw material-mixing tank of a waste plastic-treating installation for receiving the melted plastic, and subsequently successively supplying the melted plastic into a thermal decomposition tank in the next process. CONSTITUTION:In this raw material-mixing tank of a waste plastic-treating installation for receiving a melted plastic and subsequently successively supplying the melted plastic into a thermal decomposition tank in the next process, discharging pipes 7, 71 for the received melted waste plastic B are disposed at plural positions in the height direction of the inner surface of the tank, and a leveling meter 8 is disposed in the discharging pipe. Further, a port for discharging the high temperature liquid waste plastic and a port for discharging an inert gas for purging are disposed in the discharging pipes 7, 71. Since heating and purging means are disposed in the discharging pipes having the leveling meter 8, the inner clogging of the discharging pipes 7, 71 with the received melted waste plastic can be prevented. Thus, the level of the received melted waste plastic in the tank can accurately be detected. The installation can thereby stably be operated, because the received melted waste plastic can normally be supplied to the next process.

Title: Manufacture of semiconductor device
Inventor: MOCHIZUKI AKIRA
IPC: H01L21/3205
Filed: 1978-05-22
Abstract: PURPOSE: To form an electrode easily by converting the only desired part of Al wiring into an oxide through anode oxidation with the process divided into two low- tension and high-tension stages.  
     CONSTITUTION: Butadiene-based resist mask 29 which is well adhesive to Al is formed by processing Al film 27 formed on a semiconductor-element surface in N 2  of 200°C for about sixty minutes and baked. Exposed Al is anode-oxidized by a voltage of 7V to form Al 2 O 3  thin film 28 of approximately 0.3μ. The adhesion of the mask never lowers because of such this low voltage. Next, the adhesion is improved by baking and anode oxidation is carried out by a voltage of 22V to convert Al film 27 under it into Al 2 O 3  30 until its bottom. As a result, no breakaway occurs to mask 29. Next, mask 29 is removed, and Al 27 is removed by using new mask 31, which is also removed afterward. Consequently, the precision of the pattern will not lower and processing efficiency and yield will improve.

Filed: 1990-03-13
Abstract: PURPOSE:To minimize operation of an air-conditioner to save energy by a method wherein the operating status of an apparatus is measured according to power consumption, and an air flow control valve is modulated according to the measured result. CONSTITUTION:The heat generation rate of an apparatus 20 is measured as an electric energy value by a wat-hour meter 40, and a controller 42 controls the lift of an air flow control valve 36 corresponding to the measured value. When a large amount of ventilation is required, the outside air is correspondingly introduced and supplied into a room after humidified or dehumidified by an air-conditioner 38 to meet the room temperature and humidity conditions. As the room still contains heat when the heat generation rate of the apparatus 20 is particularly large, a portion of air in the room is returned to the air- conditioner 38 through a ventilation duct 34, and the mixed air is supplied into the room after cooled below the dew point by the air-conditioner 38. When the circulation air flow rate is too high, the whole air including the outside air must be cooled below the dew point and then heated again. Therefore, an optimum circulation air flow is returned from the air flow control valve 36 so that air can be supplied at the dew point, avoiding unnecessary heating.

Abstract: PURPOSE:To eliminate the need for a corresponding table of logical connection to search a packet exchange station number containing a remote DTE, by representing a DTE subscriber number with a packet exchange station number and a DTE connecting line number. CONSTITUTION:When a DTE 12 transmits a calling packet (CR packet), the CR packet is transmitted to a DTE reception control section 8 via a DTE reception line 11.

That is, the incoming packet exchange station number in the CR packet is set as it is for the reception side packet exchange station number, and the DTE connecting line number in the CR packet is set as it is for the reception side DTE connecting line number. Thus, the network header is formed without searching the corresponding table of logical connection.
