Title: Air-fuel ratio control device for internal combustion engine
Inventor: KIMURA AKIHIRO
IPC: F02D41/34
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To accurately keep the engine air-fuel ratio at the target air-fuel ratio even at the time of the transient operation. SOLUTION: An electronic control unit(ECU) 10 estimates the air quantity sucked into each cylinder of an engine based on the engine operation parameters detected by a throttle opening sensor 17, a suction pipe pressure sensor 3, and revolving speed sensors 5, 6 and calculates the fuel injection quantity from a fuel injection valve 7 based on the air quantity. The ECU calculates the fuel quantity actually fed into the cylinder based on the output of an exhaust air-fuel ratio sensor 13 and the estimated value of the air quantity sucked into the cylinder and corrects the fuel injection quantity from the fuel injection valve 7 based on the fuel quantity. The air quantity used for the calculation of the actual feed fuel quantity is calculated based on the operating parameters when the suction valve of each cylinder is closed.  The accurate feed fuel quantity containing no error is calculated, and the air-fuel ratio is accurately controlled.

Filed: 1994-10-06
Abstract: PURPOSE: To enable forging of a wheel without exchange of dies by preliminarily forming a stock loaded into a press machine through upsetting, filling up the hollow space of the dies, and piercing a preliminarily formed wheel. CONSTITUTION: A forging machine 1 is, as a basic structure, constituted of a press machine having an upper tool holder 2 holding an upper die 3. As an opposing tool, a stationary lower die 4 fixed to a lower tool holder 5 is operated. Using this device, a wheel 6d is manufactured through a single working process. Thereupon, the press machine 1 is loaded with a stock or a block 6a. The stock 6a is made into a preliminarily formed work 6b through upsetting. Through a secondary press, hollow space of the dies 3, 4 is successively filled. A preliminarily formed wheel 6c is pierced, and then central through-holes 7, 8, 11, 12 are formed. Successively, the forged wheel 6d is taken out. Thus, a series of new forging workings comprising Loading, upsetting, filling and discharging is started.

Title: Knocking sensor
Inventor: YOKOIWA SUMIHARU
IPC: G01H11/08
Filed: 1985-10-30
Abstract: PURPOSE:To obtain the resonance frequency only of fundamental vibration by removing sub-resonance generated by cavity resonance, by providing a sound absorbing material in the housing of a sensor. CONSTITUTION:A sensor is fixed to an engine by mounting the screw part 3 integrally formed to the lower part of a housing 1 to the screw hole of the engine and the vibration of the engine is transmitted to a vibration plate 4 through the screw part 3, the main body of the housing 1 and the projection 2 provided to the inner bottom part of the housing 1. As a result, the vibration plate 4 is integrated with a piezoelectric element 5 to generate mechanical flexural oscillation and the electric signal corresponding to vibration is generated between the electrodes provided to the piezoelectric element 5. When a porous sound absorbing material is provided to the gas between the inner bottom surface of the housing 1 and the vibration plate 4, an incident sound wave enters the hole of the sound absorbing material 12 or the gap and, when said sonic wave is further ready to propagate through a material, the energy thereof is lost by flow resistance caused by viscosity to the vibratory flow of air. Therefore, subresonance due to cavity resonance is removed and the resonance frequency only of the fundamental vibration of a vibration detecting body can be obtained.

Title: Method and device for inspecting print quantity of printed metal plate
Inventor: TODO EIHIKO
IPC: G06T7/00
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To precisely inspect the quantity of the printed metal plate by comparing a picked-up image with a previously set master image and deciding whether or not a print image is good. SOLUTION: The light from a light source 8 is transmitted through a polarizing filter 9 as linear polarized light 9a (linear polarized light). A CCD camera 14 receives the transmitted light 15 in an orthogonal Nicol state or parallel Nicol state by a lens and divides it into pixels, which are photoelectrically converted into an electric signal 16. When an electric signal 16 is inputted to a computer main body 17, a digital conversion part 17a converts it into a digital signal. The converted digital signal is led to an extraction part 17b. Then extracted image information is sent to a judgement part 17c. Here, it is judged whether or not the print quality is good by comparing it with respective pieces of image information stored previously in a memory 18. The result of the quality judgement is outputted immediately on a display means (monitor television etc.).

Inventor: ISODA TAKASHI
IPC: G06F3/12
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a fully duplex communication path with which the resources of a printer are reduced. SOLUTION: A printer 100 has a queue 104 for sequential execution, immediate execution agent 106 and sequential execution agent 105. The immediate execution agent 106 immediately executes a received command and writes data into a host, and the sequential execution agent 105 fetches the command from the queue and read data out of the host. At the host, on the other hand, the data transfer request from the printer 100 is inputted to the queue and, based on that request in the queue or a request from an application, the command is issued to the printer 100. In that case, the command is not issued more than the queue capacity of the printer 100. Thus, the fully duplex channel mutually independent in both up and down directions can be provided.
