Title: Ink jet recording head
Inventor: NAKASHIMA JIYUNZOU
IPC: B41J2/055
Filed: 1978-05-31
Abstract: PURPOSE:To obtain good copying functions with a simple constitution by changing the voltage being applied to a piezo element according to the presence or not and intensity of the light radiation to a photoconductor member thereby controlling the injection of ink particles. CONSTITUTION:A photoconductive plate 30 makes switching action of ON-OFF depending upon the presence or not of the received light of the light L through a transparent conductor plate 40 and therefore the switch which is closed by the received light of the light L of an electric circuit for recording head is series-connected to the piezo element 20. Since the element 20 applied with the voltage from a voltage source VS by the received light presses or deforms the wall face of a case 10, the ink J1 in the case is pressed and flies out by becoming ink particles J2 from the discharge port of the case. If at this time plain paper PP is disposed on the flying path of the ink particles J2 and is conveyed in the arrow A direction and when the ink J1 is subsequently flowed into the case 10 in the arrow B direction, then a series of recording images may be obtained on the paper PP.

Filed: 1979-05-24
Abstract: PURPOSE: To supplement clutch capacity, by providing on a shaft the secondary power transmission system having a power transmitting member connected operatively to the primary drive shaft and another power transmitting member adapted for transmitting the driving force only to the primary drive shaft, in the manner that it is operatively connected to the secondary drive shaft, and further providing a decelerating member and a member engageable therewith.  
     CONSTITUTION: In operation in which the primary power transmission system is rendered operaive but the secondary power transmission system is rendered inoperative, for instance, when a light-duty construction machine is coupled to a vehicle, a coupling member 48 is slided to the left for fixing another power transmitting member 46 to drive shaft 33 with both of the primary clutch and the secondary clutch being coupled and clutches 54, 54 of change-speed unit 52 in the secondary power transmission system being uncoupled. Since, in this state, the member 46 is held in mesh with a gear 16 on the primary drive shaft 12, driving force is transmitted to the primary drive shaft 12 via the secondary drive shaft 20 and other elements. Therefore, clutch capacity is the sum of the primary clutch 8 and the secondary clutch 9. Thus, clutch capacity can be supplemented.
