Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To maintain a picture quality at a connecting part with a configuration to prevent overwriting. SOLUTION: In order to connect two scanning lines A, B by two light beams deflected by a same reflection surface of a single rotary polygon mirror 16 as shown in FIG.

Title: Controlling apparatus for tiller
Inventor: IIDA SATOSHI
IPC: A01B63/10
Filed: 1995-02-17
Abstract: PURPOSE: To provide a controlling apparatus for a tiller capable of achieving excellent tillage while the tiller enables a quick lifting of a rotary tillage apparatus by a controlled operation with a forced lift-controlling means. CONSTITUTION: This controlling apparatus is composed of an automatic tilling depth-controlling means 18B, a forced lift-controlling means 18D and a lifting speed-controlling means 18E. A ground height-detecting means S3 detects the ground height of a rotary tillage apparatus linked to a mobile machine body freely driven in a vertical direction. The controlling means 18B controls a vertical motion of the tillage apparatus so that the ground height of the rotary tiller, determined by the detecting means S3, agree with the target ground height predetermined by a tillage depth-setting means 21. The controlling means 18D forcedly lifts the tillage apparatus until the specified lifting limit based on a lifting directive from a lift-directing switch 24 having priority to the forced actuation by the controlling means 18B.  The controlling means 18E controls the lifting speed of the tillage apparatus in such a manner that it is lower in the first half and higher in the second half in the moving range during the forced lifting of the tillage apparatus under the controlled operation with the controlling means 18D.

Title: Parallel conveyance copying machine
Inventor: HIRONO TATSUO
IPC: G03G21/00
Filed: 1985-02-19
Abstract: PURPOSE:To increase a copying speed while holding the processing speed of image formation constant by performing control which inhibits parallel conveyance unless transfer paper size determined by original size and magnification in initial mode setting is specific size. CONSTITUTION:When the 'parallel conveyance' display in an operation part illuminates, a copy mode selection is made differently according to whether or not there is an 'original' key input after a 'parallel conveyance' key is turned on. Only when the original size determined by set magnification and original size is A3 or A4, 'parallel conveyance' is displayed on a display part. Further, when copy size determined unequivocally by the original size input and magnification input in the mode setting is larger or smaller than copy size set in a paper feeding device, this parallel conveyance copying is meaningless. Therefore, the 'parallel conveyance' is displayed on the display part only when the set copy size is the copy size which is determined unequivocally during the 'parallel conveyance' display.

Title: Fuel injection time adjustment device of internal- combustion engine
Inventor: ENDOU MAKOTO
IPC: F02D1/16
Filed: 1982-02-25
Abstract: PURPOSE:To simplify the structure by rotating the output shaft on a cam shaft side of an injection pump and a control rod, and changing the phase between an input toothed wheel connected to a crakshaft and the output shaft so as to adjust the injection time appropriately. CONSTITUTION:When an engine is operated, an input toothed wheel 11 is rotated through a toothed wheel 28. Since the rotation of a control rod 16 is restrained by means of an actuator 21, a pair of differential pinions 18, 19 revolve to rotate an output shaft 14, and a cam shaft of an injection pump is further rotated. Since toothed wheels 11 and 28 are in the ratio of one to two regarding to the numbers of their teeth, the rotation speed of the output shaft 14 is decelerated to a half of the rotation speed for the input toothed wheel 11. When the actuator 21 is driven in this condition, the control rod 16 is rotated, and phase between the input toothed wheel 11 and the output shaft 14 is changed through the differential pinions 18, 19 while the fuel injection time being adjusted.

Title: Electronic acceleration switch
Inventor: HASHIMOTO YOICHI
IPC: G01P15/08
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To miniaturize an equipment by installing a hold circuit outputting a pulse signal which rises and falls synchronously with a signal of a comparator circuit output. SOLUTION: When a collision accident happens, an acceleration signal is outputted from an output terminal B of an acceleration sensor 13. Whenever the signal level exceeds the reference level of a comparator circuit 17, a pulse signal is outputted from an output terminal C. By each pulse signal, a switching transistor turns on, and a capacitor 21 is rapidly charged by the leading edge of the pulse signal. When the transistor 21 turns off, charged electric charge is gradually discharged through a resistor 23, so that the output of a circuit 26 is held at a high level. That is, when a microcomputer judges a serious collision in the period of low level between the pulse signals, an output terminal D of the circuit 26 is held at a high level, so that an ignition current can be applied to a percussion cap by the ON operation of a switching circuit.
