IPC: C22C21/04
Filed: 1981-02-04
Abstract: PURPOSE: To make proeutectic Si grains of the resulting hypereutectic Al-Si alloy fine by adding a mixture of P 2 S 5  with NaCl as a grain refiner to a molten hypereutectic Al-Si alloy.  
     CONSTITUTION: To a molten Al-Si alloy contg. 14W30% Si is added a mixture consisting of 0.01W5.0% P 2 S 5  and 0.01W5% NaCl to the amount of the molten alloy as a grain refiner. By pouring this molten alloy in a mold and solidifying it by cooling, proeutectic Si grains of the resulting hypereutectic Al-Si alloy are made fine.

Title: Fuel injection control device for internal combustion engine
Inventor: SUZUKI MICHIO
IPC: F02D41/06
Filed: 1989-01-27
Abstract: PURPOSE:To prevent an air-fuel ratio from being brought into a wide lean state during acceleration running by a method wherein, when, after the starting of an engine, a predetermined period starting from completion of warming up lapses, an increase correction factor is increased to a value higher than an increase correction value stored in a recording means. CONSTITUTION:A fuel injection control means B controls a fuel injection amount based on an output signal from an O2 sensor 19 arranged in an exhaust passage A. Under an acceleration running state detected by a detecting means C, an increase means D increases and corrects an injection amount according to a given increase correction factor, but until after the starting of an engine, a given period starting from a time when completion of warming-up is detected by a detecting means F lapses, a control means G increases an increase correction factor to a value higher than a given increase correction factor stored in a memory means E, and based on the increased factor, an injection amount is increased by an increase means D. This constitution enables fuel-air mixture to be prevented from being brought into a wide lean state during acceleration running until a specified period starting from completion of warming-up lapses after the starting of an engine.

Abstract: PURPOSE: To reduce current consumption of the calendar watch and prolong battery life by dividing calendar wheel to two or more elements, engaging one of the gears to a calendar fast correction mechanism including external operating members and engaging the other to an automatic feed mechanism.  
     CONSTITUTION: In the position where an external operating member 9 is pushed in, a sliding pinion 11 and correction wheel 10 are in a non-engaged state and an hour wheel 8 turns the hour hand and turns a date feed wheel 4 and feed finger 5 via calender intermediate wheel but in this state a display transmission wheel 3 does not rotate. When it becomes close to 0:00 AM, the protrusion 5a of the feed finger 5 engages to the tooth 3C of the display transmission wheel 3 and feeds this by 1 pitch. Since the spring 3a, tapered face part 3b integral with the display transmission wheel 3 are held engaged to the tooth 2a of the display wheel 2, the display wheel 2 is also fed by 1 pitch integrally with the display transmission wheel 3. Since in this way no jumpers are used, no load is applied at the time of calendar feeding and current consumption may be reduced.

Filed: 1979-02-16
Abstract: PURPOSE: To make it possible to read an output value by a computer and also to simulate an external signal by a program by providing a memory unit, controller, etc., and using them for both input and output.  
     CONSTITUTION: The address of memory unit 23 corresponding to lamp 10 as address signal 26, a write indication as selective signal 27 and data set up for line 25 to turn lamp 25 ON are sent to memory unit 2 by computer 21. When selective signals 28 and 29 output output signals previously, lamp 10 can come on since controller 24 has outputted the contents of memory unit 23 to a process. When input is selected by selective signals 28 and 29, controller 24 writes the state of relay 11 at a corresponding address of memory unit 23. Therefore, the content of memory unit 23 varies with the variation of the contact of relay 11. Further, a read signal is outputted as selective signal 27 from the computer and the contact address of relay 11 is assigned as address signal 26, so that the current state of relay 11 can be judged.
