Title: Idle speed learning controller for engine
Inventor: SHIMIZU HIROKAZU
IPC: F02D41/08
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To avoid such a state that learning accuracy of changed parts in a leaked air amount when a throttle valve is fully closed is lowered during unstable combustion. SOLUTION: In idle operation, an auxiliary air amount is feedback corrected so that the actual idle speed can approach a target idle speed. The corrected amount in such a feedback correction, is leaned as the learning value of changed parts in a leaked air amount when a predetermined learning condition is set up. Hereat, the foregoing learning is prohibited (S35) when the coefficient of fluctuation of an engine speed is at a predetermined value or more (S31), misfire occurs (S32) and the coefficient of fluctuation of indicated mean effective pressure PI is at a predetermined value or more (S33).

Title: Floppy disk drive
Inventor: SHIGEMASA TAKAHIRO
IPC: G11B19/04
Filed: 1989-01-06
Abstract: PURPOSE:To immediately detect an erroneous insertion of a floppy disk by providing a circuit for detecting a fact that the floppy disk is brought to erroneous insertion by outputs of a door lock detecting circuit and a normal insertion confirming circuit, and providing a buzzer sounded by the circuit. CONSTITUTION:A door lock detecting circuit 1 detects a fact that a door of a floppy disk drive is locked, and a floppy disk normal insertion conforming circuit 2 confirms a fact that a floppy disk is inserted normally. Also, a floppy disk erroneous insertion detecting circuit 3 compares both output signals of the detecting circuit 1 and the confirming circuit 2, and sounds a buzzer 4, when the floppy disk is not inserted normally. In such a way, by detecting an erroneous insertion of the floppy disk and informing it by the buzzer, the erroneous insertion of the floppy disk can be known, and when read and write cannot be executed, it is unnecessary to consider the cause by such a primitive miss as an erroneous insertion of the floppy disk.

Title: Fluid treatment apparatus
Inventor: ITAGAKI YOSHINORI
IPC: A61M1/18
Filed: 1989-01-10
Abstract: PURPOSE:To easily detect an inferior product by a method wherein the communication of the internal and external spaces of a housing is cut off when a seal material is arranged to an insertion groove and the communication passage of both spaces is formed when said seal material is not arranged. CONSTITUTION:The liquidtight connection of the housing main body member 3 and blood port forming members 5a, 5b of an artificial kidney is performed by cutting a part of the peripheral edge part of an enlarged end part becoming a contact surface over the entire periphery thereof to provide an insertion groove 10 and arranging an O-ring 11 to said groove 10 but the contact surface is further cut in a slit like state by the shallow detection groove 14 reaching an end 13 on an outer peripheral side from an end part 12 on an inner peripheral side so as to cross the insertion groove 10. When the artificial kidney is assembled normally, the flow passage reaching the outside from the internal space of a housing 1 is interrupted in continuity by the O-ring 11 and liquidtightness is kept but, when said kidney is assembled without arranging the O-ring, the flow passage is held to a continuous state as it is and, therefore, the liquidtightness is lost. As a result, an inferior product can be easily detected by investigating the presence of the leakage of a fluid in the connection parts.

Title: Method and device for correcting acoustic-optical deflection error of light beam
IPC: G02F1/11
Filed: 1993-01-11
Abstract: PURPOSE: To compensate the wavefront error of an acoustic-optical deflector having a high scanning speed and a wide walk-off angle by providing the deflector with a deflecting means for neutralizing dependency upon the deflection angle of width of a deflected beam. CONSTITUTION: A geometric error is compensated by 2nd subsidiary deflection 28 in a deflection face 29 and reverse angle dependency against beam width is generated. The subsidiary deflection 28 is generated at an angle applied in the deflection face 29 independently of time or a deflection angle and also independently of scanning speed. The diameters 32, 33 of beams arrived at different points of time are equal and fixed on a scanning line or the like during the period of scanning. New sets 31, 32 of virtual devergent points are generated on a face rectangular to the axis of a cylindrical lens 13 and an objective lens 22. Namely, virtual light source points exist on distances equal from the lens 13 or the lens 22. Consequently, wave front errors in a beam are reduced and a focus based on the objective lens 22 keeps a complete shape.

Title: Memory access system
Inventor: WAKAMATSU AKIHIRO
IPC: G06F12/00
Filed: 1985-01-11
Abstract: PURPOSE:To remove weight cycle of a CPU and to speed up reading and writing operation of a memory by outputting a -RAS signalsynchronously with the head machine cycle regardless of memory request and activating a -CAS signal at the time of memory request. CONSTITUTION:The -RAS signal is outputted automatically making an -ALE signal a trigger regardless of memory request. However, a -CAS signal is outputted only when a memory request signal (MRQ) is inputted from CPU at the time of memory access cycle time in which DRAM is accessed in consideration of weight request from external I/O in DMA. At reading a memory when an MR signal is at high level, -CAS.R is selected and supplied to a column designation terminal C. On the other hand, at the time of memory write when an MW signal is at high level, -CAS.W which is a -CAS signal for memory writing, is formed by selecting a signal made by delaying the -CAS signal 160 by a specified time by a delay circuit 18 by a -CAS signal selecting circuit 17 and outputted. Thus, read/write operation of a DRAM13 in bus cycle free from weight cycle can be executed.
