Patent JP-H0571390-A (JP)
Title: Fuel injection amount control method for internal combustion engine
Inventor: TAKAHASHI MINORU
IPC: F02D41/12
Filed: 1991-09-12
Abstract: PURPOSE:To ensure a theoretical air-fuel ratio even during the re-start of fuel injection, so as to attempt prevention of contamination of exhaust gas and improve engine response by setting a first fuel injection amount after the re-start of fuel injection to a valve at least one time or more as large as a fundamental injection amount to satisfy the theoretical air-fuel ratio. CONSTITUTION:An ECU 4A controls the opening time, of a fuel injection valve 3a i.e., a fuel injection amount, based on detection signals from the pressure sensor 7a of a surge tank 2A, the crank angle sensor 18 of a crank shaft, the water temperature sensor 15 of cooling water 14. Fuel is intermittently injected in synchronism with rotation of an internal combustion engine and fuel required for one combustion is injected in a state to be divided into at least two lots. In this case, the ECU 4A re-starts injection of fuel when a throttle 5a is opened after injection of fuel is stopped when there is no need for the feed of fuel in a deceleration state wherein the throttle 5a is fully closed. A first fuel injection amount after the re-start of injection of fuel is set to a valve at least one time or more as large as a fundamental injection amount to satisfy a theoretical air-fuel ratio.

Title: Object detector
Inventor: MASUDA MASAYUKI
IPC: G01V8/12
Filed: 1992-09-01
Abstract: PURPOSE:To set a distance used as a reference for detection of an object easily at high accuracy, in an object detector using a PSD. CONSTITUTION:The output of a PSD 33 is integrated by integration circuits 38 and 39 in synchronizm with the timing of projection through I/V conversion circuits 34 and 35. When the output of the integration circuit 38 reaches a threshold V0, the output signal VCOM of a comparator circuit 44 moves to a low level and, hence, the output of the integration circuit 39 is digitized with an A/D conversion circuit 45 to be transferred to a control means 20 as distance data. While an operating section 46 is operated, a distance data outputted from the A/D conversion circuit 45 is written into a memory 47. Otherwise, the control means 20 transfers the distance data to a comparator 48. The comparator 48 compares the current distance data transferred from the control means 20 with the distance data as reference value of a distance stored in the memory 47 to output a signal representing whether an object exists or not.

Title: Method of embedding ferrous sintered metal by casting
Inventor: SUGANUMA TETSUYA
IPC: B22D19/02
Filed: 1982-12-27
Abstract: PURPOSE:To eliminate the oxidation and decarburization of a ferrous sintered member to be mebedded by casting and to improve the joining property to a member for mebedding by casting by coating uniformly fine graphite particles on the surface of the sintered member, setting the same in a casting mold and embedding the member by casting. CONSTITUTION:Fine colloidal particles of graphite are uniformly coated on a member formed by sintering Fe alloy powder to about <=5% void volume, for example, a rocker arm chip 1, and the chip is set in the prescribed position in a casting mold 4 and is pressed to a metallic mold 7 for chilling. A molten cast iron for embedding by casting is charged through a sprue 5 into a cavity 6 to embed the chip 1 by casting, whereby a required raw material for the rocker arm is obtd. The graphite film on the surface of the chip 1 breaks the contact of oxygen with the surface of the sintered material and the fine particles of graphite improve the joining property between the chip 1 and the member for embedding by casting. The hardness of the chip 1 is further increased by the metallic mold for chilling. The decarburization phenomenon of the sintered material is thus eliminated and the joining property to the member for embedding by casting is improved.

Title: Coordinate position detector
Inventor: SATO HIDEKI
IPC: G06K11/06
Filed: 1988-09-19
Abstract: PURPOSE:To fulfill two function inputs with the same contact operation of one cursor by providing an input means with plural induction coils and capacitors connected to them. CONSTITUTION:An induced voltage is caused in an induction coil L of a cursor 30 or an input pen by electromagnetic induction to charge a capacitor C connected to the induction coil. Next, this operation is switched to reception to discharge the electric charge in the capacitor C to the induction coil L, and the reception signal flowing in a loop coil 2 for reception is taken out to calculate the contact coordinate position of the cursor 30. Since one input means like the cursor is provided with plural induction coils different in resonance frequency, a loop coil reception circuit takes out plural reception signals by the difference of resonance frequency and processes them when the cursor 30 is brought into contact with a detection plate for coordinate input. Thus, plural functions preliminarily set for each resonance frequency can be inputted.

Title: Bearing of rotary piston type machine and transmission structure
Inventor: DANKUUARUTO AIERUMAN
IPC: F01C21/06
Filed: 1990-09-06
Abstract: PURPOSE: To reduce the contact area of a bearing bush and distribute a mixture or suction air by mounting the bearing bush in a tooth cutoff portion of an internal gear to form a passage in a space to a tooth bottom. CONSTITUTION: At part of an internal gear 11 formed on a piston 1, another hole 16 is formed as a bearing hole 14 with the diameter ranging between a tooth end 18 and a tooth bottom 17. In this way, the teeth 13 of the internal gear 11 are cut off to form a tooth cutoff portion 19. A bearing bush 15 for a roll bearing 2 is mounted on the tooth cutoff portion 19. An axial passage 20 is thus formed between the outer periphery of the bearing bush 15 and the tooth bottom 17. As the contact area of the piston 1 with the bearing bush 15 is therefore reduced, the movement of contact heat transmitted from a combustion chamber through the piston 1 can be reduced. A mixture or suction air absorbed by the piston 1 is distributed in the passage 20, and so the roll bearing 2 is effectively cooled.
