Title: Defeat device
Inventor: SASAKI MITSUGI
IPC: H04N5/44
Filed: 1979-03-14
Abstract: PURPOSE:To obtain the pulse which is expanded for defeating with no time delay, by inserting the diode forward into the charging loop of the time constant circuit. CONSTITUTION:When the defeat command pulse is given from output terminal 4 of transistor 3, capacitor 7 is charged quickly via diode 15 and resistance 8. At the same time, command pulse is applied to the base of transistor 5 via resistance 16, and thus transistor 5 is turned ON. When no command pulse exists, the discharging is given for capacitor 7 via resistance 10, diode 11 pulse the emitter and the base of transistor 5 each, and thus transistor 5 is turned ON continuously for a fixed time. As a result, transistor 17 is turned ON to actuate the defeat circuit.

Title: Valve closing device
Inventor: DANNO YOSHIROU
IPC: F01L13/00
Filed: 1983-02-25
Abstract: PURPOSE:To surely prevent malfunction from occurring by a method wherein a cam is loosely fitted onto a camshaft in the valve gear system of an internal combustion engine and an oil replenishing passage for ensuring the holding of a plunger, which is engaged with and disengaged from said cam in the camshaft, in the disengaged position is provided in the camshaft. CONSTITUTION:When an output signal is issued from a controller 14 so as to change-over an oil control valve 13 in order to lead pressure oil through an oil pipe 12 to the oil passage 201 in a camshaft 2 during light load running or the like, a plunger 19 in a guide hole 18 formed in the diametral direction of the camshaft 2 is shifted against a spring 21 from a position, at which the plunger 19 engages with the engaging dent 163 of a cam 16, to a position, at which the plunger 19 engages deeply in a guide hole 18. As a result, the camshaft 2 slides in the cam 16 instead of rotating the cam 16 and a suction and an exhaust valves are kept at the fully closed states. In this case, a plurality of oil replenishing passages 23 are fromed radially in the camshaft 2 so as to apply the pressure oil in the oil passage 201 in the camshaft 2 to a ramp groove 24 and the engaging dent 163 in order to ensure the retreat of the plunger 19 into the guide hole 18.

Title: Excitation regulator of ac generator
Inventor: MATSUNAGA TETSUO
IPC: H02P9/08
Filed: 1983-02-25
Abstract: PURPOSE:To enable to smoothly start a load by providing means for increasing the detected voltage when the output current of a generator is larger than the prescribed value. CONSTITUTION:When a breaker SW is closed, a current is flowed to a motor M, and the output voltage and current of a generator 1 are raised. At this time, the output current of a detecting current transformer CT, i.e., the current inputted to the primary windings 13-15 of a transformer 9 increases. When the voltage of the connecting point of a resistor R and a constant-voltage diode ZD becomes the prescribed value or higher, the thyristor S1-S6 are conducted. Thus, the output voltages of the other primary windings 13-15 are vector-combined with the output voltages of the primary windings 10-12, the detector voltage apparently becomes large, and the output voltage of the generator 1 is suppressed. When the rotating speed of the motor M rises so that the motor current decreases, the thyristors S1-S6 are interrupted, triacs T1, T2 are conducted, and the output voltage of the transformer 9 becomes only the output voltage based on the primary windings 10-12.

IPC: B29C45/26
Filed: 1985-02-21
Abstract: PURPOSE:To permit to release the accurately molded plastic lense from the mold under maintaining the high accuracy thereof by a constitution wherein molten resin in a cavity is pressurized and formed by a sliding nesting, then, the resin is cooled and solidified and, thereafter, the sliding nesting is retreated under a condition that the resin in the cavity is fixed and held by a fixed mold and movable mold. CONSTITUTION:When an injection molding machine 10 is put ON, the molten resin is injected out of the injection molding machine 10 and at cavity is filled with it. In this case, the sliding nesting 5 is retreated by the filling pressure of the resin. When the finish of filling of the resin into the cavity 1 is detected by a control unit 11 through the advancing speed of a screw, injection pressure and the amount of movement of the sliding nesting 5, which is detected by a position detector 9, a hydraulic cylinder 7 is driven by the control unit 11. Then, the sliding nesting 5 is advanced and the resin in the cavity 1 is pressurized by the sliding nesting 5 and a movable nesting 6. Pressurizing, effected by the sliding nesting 5 and the movable nesting 6, compensates the amount of contraction of the resin due to the solidification thereof and the plastic resin may be molded highly accurately.

Title: Image-supplying device
Inventor: MAKITA MINORU
IPC: G03G15/00
Filed: 1991-01-31
Abstract: PURPOSE:To shorten processing time and to simplify data transmission routine for an image-supplying device in which images are printed with printing modes being switched over. CONSTITUTION:A memory area that is only for data reception is maintained in a memory of an image-supplying device, and the said memory area is made such that is not initialized by a program that processes individual printing mode. Therefore, initialization of the memory area only for the data reception is not necessary when switching from one mode to another one is made, and the image-supplying device does not need to be off-line to a host computer, resulting in shortening of processing time. As erasion of received contents occurring whenever the switching over of the mode is made can be prevented by arrangements as mentioned above, sending of necessary data (such as command for processing of mode) from the host computer to the image-supplying device can be made without regard to confirmation to be made on completion of the switching over of the mode.
