IPC: F02D29/04
Filed: 1988-04-30
Abstract: PURPOSE:To prevent a drop in engine rotational speed during return to fuel supply while ensuring minimum cooling ability by providing a means for changing the capacity of a compressor to a minimum value for a predetermined time during transition from the stop of fuel supply to the return to the fuel supply. CONSTITUTION:During deceleration of an engine 1, a fuel cut-off means stops the supply of fuel to the engine. During transition from the stop of fuel supply to the return to fuel supply, an actuator 25 is operated in response to an instruction signal from a control unit U so as to displace a suction port 23 opened to a side housing of a compressor 20 toward the rotationwise advancing side of a rotor 21 so as to set the capacity of the compressor 20 to a minimum value for a predetermined time. The load of the compressor 20 upon the engine is decreased to a value as small as possible during the period of return to fuel supply during which the fuel supply is unstable. As a result it is possible to prevent a drop in rotational speed of the engine 1 while ensuring a minimum cooling ability during return to fuel supply.

Title: Ink jet recording device
Inventor: YAMAMORI SEIJI
IPC: B41J2/045
Filed: 1989-04-26
Abstract: PURPOSE:To improve the integration density of nozzles and decrease the size of a head by the arrangement such that a first room is connected with a second room through a connection passage and a pressure raising means is provided with a heating element to cause ink droplets to fly, through air stream. CONSTITUTION:A small heating element 18 is provided in a portion of wall of a pressure room 10 and when an image input signal 40 is applied to the element 18 through a lead electrode 30, an abrupt temperature rise is generated in the element 18, causing the ink in contact with the element 18 to boil instanta neously, whereby bubbles are generated. The bubbles generated cause abrupt pressure rise in the room 10, whereby the ink therein is sprayed in the form of jet stream from an ink connection passage 11 to be delivered from an ink delivery port 3 in the form of ink droplets. The ink droplets delivered are accelerated by an air steam flowing out of an air delivery port 1 at high speed, so that the droplets fly through the air and are attached to a recording medium, whereby recording images are formed. On the other hand, in the room 10 from which ink has been forced out, the bubbles diminish as the temperature of the element 18 falls, causing negative pressure therein, so that the ink in an ink room 9 flows thereinto through the passage 11.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To enable the fuel injection timing and the fuel injection time to be accurately detected by making the relationship between displacement of a permanent magnet and output of a hall element linear. SOLUTION: A permanent magnet 6 is fixed to the end part 2a of a pressure pin 2 by a cover 7 made of non-magnetic material.

A hall element 8 is arranged at the position which faces the center part in the direction in which the permanent magnet 6 is magnetized, and which does not exceed both magnetized poles or both ends of the permanent magnet 6 even the permanent magnet 6 reciprocates in the axial direction of a nozzle holder 1. The hall element 8 is sealed in a holder 9 with resin 25, and the holder 9 is screwed in a lateral hole 1c in the radial direction of the nozzle holder 1. Thus, linearity of the relationship between displacement of the permanent magnet 6 and output of the hall element 8 is maintained during the period of operating a fuel injection device 10.  The fuel injection timing and the fuel injection time can thus be accurately detected.

IPC: G06F12/08
Filed: 1988-05-06
Abstract: PURPOSE:To assure the coincidence between the contents of a cache memory and those of a main memory without increasing the occupation rate of a CPU bus. CONSTITUTION:A 2nd cache memory 16 controls the control information C1 of its own and also the address information corresponding to the data fetched by a 1st cache memory 12 based on the address information AD2 received from a CPU 13 and a 2nd control information C2 which specifies either one of blocks in the memory 12. In other words, an external cache memory (a second cache memory 16) controls a block of a specific address of an internal cache memory (the first cache memory 12). Furthermore the memory 16 checks the write addresses set on a main memory bus 14 and decides whether an invalidation address should be informed to the CPU 13 or not. Thus the control is carried out so that a CPU bus 11 is used only when said information of the invalid address is required.
