Title: Optical control element
Inventor: SUZUKI MASAYUKI
IPC: G02F1/17
Filed: 1984-04-06
Abstract: PURPOSE:To form an optical control element which has no special restriction in an incident form, etc. of an incident light, and also is excellent in stability and durability, by moving granules by changing partially the temperature of a liquid, and providing a light shielding body on a part of a moving path. CONSTITUTION:Since light shielding filters 35, 35' are provided, a luminous flux 101 which advances so as to pass through in a liquid layer 33 being in the vicinity of a heating resistor 34a is made incident on the liquid layer 33, but a luminous flux 102 which advances so as to pass through in the liquid layer 33 being in the vicinity of a heating resistor 34b, and a luminous flux which advances in order to pass through other part are shielded by a light shielding body and are not made incident on the element. Accordingly, when a granule 30 is held in the vicinity of the heating resistor 34b, the incident luminous flux 101 transmits the light transmitting liquid layer 33, travels straight as it is and is emitted. On the other hand, in when the granule 30 is held in the vicinity of the heating resistor 34a, the incident luminous flux 101 is effected by the granule and emitted in a wave front state different from the straight traveling. The incident luminous flux 101 can be controlled by controlling the position of the granule 30 in the liquid layer 33.

IPC: B41J2/055
Filed: 1994-04-05
Abstract: PURPOSE:To prevent a nozzle from becoming contaminated by an adhesive by irradiating a nozzle plate with a laser beam through a communicating hole in an auxiliary nozzle plate member, and junctioning the communicating hole in the auxiliary member for nozzle plate with an ink liquid chamber so that these communicate with each other, after the fabricating of a nozzle to a nozzle plate. CONSTITUTION:First the lateral faces of a piezoelectric ceramic plate 102 and an auxiliary member 105 for nozzle plate are matched to a common surface, and a nozzle 132 and an ink liquid chamber are arranged at their mutually opposed position by a simple method such as junctioning. Thus productivity is high and a junctioning step is less costly. In addition, when forming the nozzle 132 after junctioning a nozzle plate 131 to the auxiliary member 105 for a nozzle plate, there are no possibilities that an adhesive might run into the nozzle 132 to clog the nozzle, as is the case with a conventional manufacturing method. Thus, the yield is improved.

Filed: 1992-03-26
Abstract: PURPOSE:To surely prevent instruments such as a switch and a plug socket from coming off by preventing an inner frame from expanding outwards by an external force and then deflecting and deforming. CONSTITUTION:In a round-type wiring instrument, fitting holes 13 are formed in side pieces 12 which face each other and fitting projections which project from both ends of an instrument located in the inner frame are inserted into the fitting holes 13 and then are fit in with the holes. In order to prevent side pieces of the inner frame 9 from deflecting outwards and then deforming due to a space formed between the inner frame 9 and a plate frame 1, a deflection and deformation preventing projection A is formed on an outer face of the side piece 12 of the inner frame 9 or on an inner face of an opening 2 of the plate frame 1 and the end of the deflection and deformation preventing projection A is caused to abut the face where the projection A is not formed. By this method, the side piece 12 of the inner frame 9 is prevented from expanding and then deflecting and deforming even if an external force is applied.

Abstract: PURPOSE:To measure the weight of a body suspended from a crane in a short time by using a load cell and an accelerometer. CONSTITUTION:The load cell 4 and accelerometer 5 are fitted to the lower part of the cable 3 of the crane and the body 2 drawn up from the water is suspended under the load cell 4.

Abstract: PURPOSE:To suppress the rotating speed of a head arm by generating a counter electromotive force in a coil part, and reducing the inertia force of the coil part when the runaway of a voice coil motor occurs and a centrifugal force generated in the head arm is increased. CONSTITUTION:When the rotating speed of the head arm 2 is increased due to the runaway of the voice coil motor 5, the centrifugal force acting on a displacement member 14 is increased thereby.

Thereby, the displacement member 14 is separated from contacts 18, 18, and the supply of a driving current from a motor driver 23 to the coil part 6 is blocked. A circuit closed via lead wires 20b, 20c, the displacement member 14, and a contact 19 can be formed at the coil part 6 by bringing the displacement member 14 into contact with the contact 19, and the counter electromotive force is generated from a moving coil part 6, and the inertia force of the coil part 6 is reduced, which suppresses the rotating speed of the head arm 2.

Filed: 1986-03-27
Abstract: PURPOSE:To improve the reliability by providing a main and a sub loop and a data control circuit in an optical local area network so as to prevent the effect of a fault onto the entire network in the occurrence of a local fault. CONSTITUTION:If a fault such as an open line takes place this side of the loop of a main transceiver 6, the transceiver 6 receives neither a data signal nor a pilot signal, and it is detected by a main signal discriminator 10 of a data control circuit 9. Then the control oepration of a switch controller 17 is changed over and the signal fetch from the main loop is interrupted and the signal is fetched from the sub loop via a sub transceiver 7. Further, the signal transmission to the next stage of the main loop is continued and the transmission of the pilot signal to the sub loop next stage is interrupted. Since the signal is sent reflectedly from the main to the sub loop or from the sub to the main loop in this way, the data transmission state is ensured by the normal line, the effect of the fault onto the entire network is prevented to improve the reliability.
