Title: Automatic tray supply device
Inventor: ITO SADAAKI
IPC: B65G59/10
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To peel automatically trays one at a time and cause each to fall down, by pushing the side-faces of the stack of trays by a rotating means, thereby curving and deforming temporarily the tray situated at its lowermost end and peeling it off. SOLUTION: From the condition in which the flange parts of a stack of trays 1 are supported with the leading ends of L-shaped tray-support devices 2, both side-faces of the trays 1 are pushed by a rotating tray-pulling/-peeling member 3. Consequently, the trays 1 are deformed and air enters the part where the trays 1 one above the other are in close contact with each other, and the stack of trays 1 on the tray 1 situated at its lowermost end slides and floats due to the inclinations of the draft angles of the side-faces of the trays 1, which are formed during the molding of the trays. As a result, the force with which both the side-faces of the trays 1 are pushed is concentrated on the one tray 1 situated at the lowermost end, the tray 1 at the lowermost end is deformed more and more, and its flange part comes off the tray support devices 2.  Also, it is peeled off downward by the rotation of the tray-pulling/-peeling member 3, and only the one tray 1 at the lowermost end falls down.

Title: Ignition timing controller for internal combustion engine
Inventor: YAMADA HIROSHI
IPC: F02P5/15
Filed: 1986-10-31
Abstract: PURPOSE:To prevent erroneous judgement of knocking even under a transient condition, by preparing a referential knocking level for a knocking decision means corresponding to a referential knocking level memory means and a correction means. CONSTITUTION:A microcomputer 6 is provided with an output from a comparator 5 for comparing a peak value of a knocking vibration detection signal fed from a knocking detector 1 through a filter circuit 2 with an output from a resistor ladder 7 for applying D-A conversion onto an initial referential level, i.e. a digital signal, for every engine condition contained in a microcomputer 6. Corresponding to the number of pulses counted on the basis of said comparison results, a moderating quantity is incremented/decremented for the previous referential level to provide a current referential level, so as to obtain an approximately central value of the peak value of the knocking vibration detection signal. Consequently, following performance of referential level is improved even when the value of signal outputted from the knocking detector 1 varies remarkably.

Abstract: PURPOSE:To obtain a reading signal removing noise of a fixed pattern by turning the second switching element on to read the signal, turning the first switching element on and off, thereafter reading the signal again, subtracting this to obtain an output signal and successively repeating operations on respective picture elements. CONSTITUTION:When a MOS transistor TR11 is turned on by a digital signal phiS1, a signal charge stored in a parasitic capacity C1 is read from an output terminal 11 as a voltage by a buffer amplifier BA1. At this time, not only a noise component but also a noise component on which an offset voltage due to a residual charge of a BA1 and an A points is overlapped is included. Then, a TR21 is turned on by a digital signal phiR1 to make the potential of the A point zero, and thereafter, the TR21 is turned off, the voltage of the A point is read by the signal phiS1 by making the offset voltage by the residual charge to obtain the noise component. From photoelectric transducers LE2-LEn, the signal component and the noise component including the noise are successively obtained. Thereafter, the signal component out1 including the noise is delayed by a changeover switch 15 to subtract a noise component out2 by a differential amplifier 13 and an output signal 3 is obtained.
