Title: Fuel control device for electronic fuel infection type engine
Inventor: KIDO YOSHINOBU
IPC: F02D41/02
Filed: 1986-07-25
Abstract: PURPOSE:To enable an optimal intake limitation to be carried out while follow ing up the changes of charging efficiency, by providing an intake charging efficiency changeover means which changes over the charging efficiency of intake air to be supplied to an engine so as to be variable, and a changing means which changes the set value of fuel injection quantity in response to the changeover of the charging efficiency. CONSTITUTION:While a fuel injection control system 102 controls the fuel injec tion quantity of a fuel injection means 101, it carries out a limit control so that the injection quantity is brought within the range of limiting values 103. On the other hand, an intake system has a supercharging means 105, and a charging efficiency changeover means 104 changes the charging efficiency of the supercharging means 105, and at the same time, in response to the change over, changes or alters also the values of the limiting values 103. Thus, an optimal control of fuel injection quantity limitation can be carried out.

Title: Thermal printer
Inventor: NAGAO HISAO
IPC: B41J2/355
Filed: 1980-12-09
Abstract: PURPOSE:To avoid idle time and to improve printing speed in the case a plurality of digits are consecutively printed in a short time, by starting the heating driving of a printing head before the printing head stops at the position of the next digit. CONSTITUTION:The movement of the printing head 1 to the next digit is performed by a pulse motor 2. A control circuit 6 generates a timing signal S19 at a specified time before a printing head 1 stops. Since a printing command signal PR is generated at said generating time, the heating driving of the printing head 1 is started before the printing head 1 stops at the next digit position. Since time delay is accompanied by the increase in the temperature of the printing head 1, said time delay is utilized so that the heating state reaches the temperature required for printing when the printing head stops at the next digit position. In the conventional method, the heating driving is performed after the printing head has completely stopped, and the delay of the increase in the head temperature is made as an idle time. This idle time is removed.

Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a high frequency filter circuit most suitable to an input filter circuit to surely secure its connection with high reliability or to satisfactorily eliminate the connection by using the high frequency filter circuit of the fixed input frequency provided on a printed circuit board to prescribe the pattern width, the least inter-line distance, the inter-adjacent coil distance or a grounded conductive pattern prepared between the coils of the printed circuit board.

Title: Ink jet head
Inventor: IWAZAWA TOSHIYUKI
IPC: B41J2/06
Filed: 1988-07-13
Abstract: PURPOSE:To reduce a voltage loss caused by a voltage drop by providing an ink electrode on the inner wall of an ink discharge port. CONSTITUTION:An ink is supplied to an ink supply port 1 from an ink tank to be loaded on an ink chamber 2. Simultaneously when an air having a pressure Po slightly higher than atmosphere is always supplied from an air supply port 4, an air pressure of the value Po is applied also to the ink tank. In this state, the ink forms a meniscus on an ink discharge port 3 on the side of an air chamber 5. When a high voltage drive signal 9 is applied between an ink electrode 7 and a common electrode 8 in this state, the small component of resistance of the ink also reduces a loss by a voltage drop because of the inner wall of the ink discharge port 3 serving as the ink electrode 7. Thus, the electrically charged ink forming the meniscus is drawn toward the common electrode 8 with good efficiency. This drawn ink is accelerated by an air flow to be discharged outside a head vigorously.

Title: Semiconductor device
Inventor: ABUMITSUKA TOSHIYUKI
IPC: H01L21/822
Filed: 1984-08-22
Abstract: PURPOSE:To prevent the deterioration in element hold time due to the stress during assembly by a method whrein active elements are not arranged in the neighborhood of corners of scribe lines. CONSTITUTION:The active element is arranged at a distance of about 200mum or more from the corner of the scribe line in order to prevent the deterioration in characteristics of the active element due to the stress in a chip. For example, a 256K D-RAM is produced on a P type Si substrate by a normal MOS process and then used as the sample, and the hold time for the active element is measured before and after this sample is fixed to the case. The result shows correlation between the intrachip position of the active element and the hole time with respect to the sample after fixing to the case: the holding time becomes shorter with smaller distances by the use of the element located within about 200mum from the corner of the scribe line.
