IPC: B41J2/045
Filed: 1991-05-23
Abstract: PURPOSE:To solve the problem of thermal decomposition of ink by a constitution wherein pressure gas is fed, synchronously with ON/OFF control operation of an ON/OFF valve, from a high pressure gas supply section into the ink channel of a nozzle in order to deliver the ink through the opening of the nozzle thereby eliminating the heating operation of ink. CONSTITUTION:Ink 5 in an ink tank 3 flows through capillary action into the ink channel 8a of a nozzle 2 and fills the ink channel 8a. When an ON/OFF valve 7 of a gas tank 4 is opened by an electrical signal, gas 6 in the gas tank 4 enters into the ink channel 8a filled with the ink 5 which is thereby delivered, together with the gas, through a nozzle opening 8b. Upon subsequent closure of the ON/OFF valve 7, the ink channel 8a is filled again with the ink 5 fed from the ink tank 3. When the ON/OFF valve 7 is operated repeatedly, the ink can be delivered continuously without requiring heating operation.

IPC: G02B6/12
Filed: 1986-06-24
Abstract: PURPOSE:To facilitate manufacture and to reduce transmission loss by forming the main body part of a branch-side waveguide to the width or in the section of a multimode type. CONSTITUTION:Branch-side waveguides Cb1 and Cb2 have mutually equal waveguide width d1 and a trunk waveguide Cm with waveguide width (d1+d2) is coupled with the branch-side waveguide Cb1 to its overall waveguide width d1 at the part of the trunk waveguide Cm with waveguide width d1 and with part of the branch-side waveguide Cb2 at the part of the trunk waveguide Cm with the remaining waveguide width d2. The waveguide width d1 and waveguide width d2 are set to a desired ratio, e.g. 20:1. Consequently, unequal distribution is attained and an optical signal incident on the branch-side waveguide Cb2 hardly enters a radiation mode because the branch-side waveguide Cb2 itself is in multimode, so that the transmission loss is reduced.

Title: Regenerative braking device for dc shunt motor
Inventor: SAITOU TETSUO
IPC: H02P3/14
Filed: 1978-11-29
Abstract: PURPOSE: To reduce circuit losses, operate efficient regeneration and operate smooth braking, by suppressing the back electromotive force of a DC shunt motor below a specified value and thereby suppressing the storage buttery charging current below a suitable level.  
     CONSTITUTION: When storage battery terminal signal VB exceeds reference voltage V 20 , signal V 21 , which is proportional to this, is outputted from voltage comparator 35 and it becomes a negative input of subtracter 36. As the positive input of subtracter 36 is given field current command signal V 6 . When storage battery terminal signal VB is larger than reference voltage V 20 , the actual field current becomes smaller than the value corresponding to field current command signal V 6 . For this reason, the back electromotive force of armature 2 decreases, and as a result, storage battery terminal voltage VB is suppressed below a certain value with respect to reference voltage V 20 . When storage battery terminal voltage VB is smaller than reference voltage V 20 , the output of voltage comparator 35 becomes zero.
