Title: Ink-jet head and recording apparatus using the head
Inventor: KURIHARA TAKAAKI
IPC: B41J2/16
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To improve a seal reliability, reduce costs and simplify processes by sealing an electric coupling part of a printed wiring and/or a seal point of a contact part of ink with a substance composed of an epoxy resin. SOLUTION: A substrate having a heater and a driver formed in a general- purpose silicon process is die bonded to a base plate. A discharge hole is formed to a top plate, and the discharge hole and the heater are fixed by a spring, whereby a spring combination part is obtained. A silicon rubber sheet is sucked and tightly adhered to a mold of a transfer mold. The spring combination part is set in the mold. An epoxy resin 1007 is filled in the mold and set. An ink-jet head using the thermosetting epoxy resin is thus formed. Because of the use of the epoxy resin, an invasion of air bubbles is reduced and an adhesive strength to a structural member of the ink-jet head is prevented from being deteriorated. A seal process can be simplified by molding in one operation with the use of the epoxy resin.

Title: Rotary armature for dc motor
Inventor: TSURUOKA KAZUHIRO
IPC: H02K1/28
Filed: 1982-10-29
Abstract: PURPOSE:To eliminate the necessity for accurately processing work at a coupling portion by coupling a rotational shaft to a supporting plate by a plastic deformation, thereby enhancing the reliability of the coupling portion. CONSTITUTION:An annular recess 18a which is formed with many projections is formed circumferentially on the bottom of a coupling portion of the outer periphery of a rotational shaft 18 to a metal supporting plate 19. The peripheral edge side of the engaging hole of the plate 19 which has a rotational shaft engaging hole at the center is pressurized in the state that the annular recess 18a of the shaft 18 inserted into the engaging hole is opposed to the wall surface of the engaging hole, thereby plastically deforming the peripheral edge to swell the wall surface of the engaging hole toward the center so as to be flowed into the recess 18a. Thus, the shaft 18 and the plate 19 are integrally coupled.

Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To easily retrieve/reproduce a required voice message and to avoid complex procedure so as to input an ID at every time of sending by retrieving a voice message containing a key word among the stored voice messages. SOLUTION: A key word storage part 105 beforehand converts the key word of prescribed contents to a voice parameter to store it. A voice recognition part 106 operates the voice parameter related to the voice message stored in a voice message storage part 108, and operates similarity between the voice parameter of the key word stored in the key word storage part 105 and the voice parameter of the voice message to compare them. Then, the voice recognition part 106 retrieves the voice message containing the key word from the voice messages stored in the voice message storage part 108. In such a manner, since the voice message containing the key word is retrieved from the voice messages, a sender doesn't need to use an ID code, and the required voice message is reproduced preferentially.

Title: Manufacture of composite shaft
Inventor: YAMAMOTO SHIRO
IPC: B29K105/04
Filed: 1991-07-04
Abstract: PURPOSE:To improve the balance of a formed composite shaft and to enable its mass production to be achieved, while a metallic joint may be easily fitted to the main body of the shaft by a method in which the hollow cylinder having been made is rotated at high speed, and thereinto fiber and resin are introduced, and then the fiber is wound up onto the cylinder and the resin is cured, whereby FRP is formed on its inner surface. CONSTITUTION:The cylindrical outer shell 11 made of metal to which a metallic joint 2 is fitted, is rotated at high speed by a rotary motor 8. The resin forcing fiber 3a having been fed is introduced on the inner wall of the outer shell 1 and is wound up on the inner surface, and then the layer 3 of reinforcing fiber is formed. Liquid thermosetting resin is poured into the cylindrical outer shell 1 after the reinforcing fiber has been wound up generally. That is to say, spray is applied to the reinforcing fiber-layer 3 taken up from a raw resin-tank 9, and said resin is attracted into the reinforcing fiber-layer 3 by centrifugal force. Then, since the resin is sucked only in the gap of the reinforcing fiber-layer having been already formed, the fiber content of FRP layer may be heightened, and the formed object with excellent balance is obtained.

Abstract: PURPOSE:To obtain a stable characteristic, by applying a voltage to a diaphragm formed with a synthetic resin having elasticity mixed with carbon particles and changing electric signals flowing to the diaphragm via the change in the resistance value of the diaphragm through the compression and expansion of the diaphragm. CONSTITUTION:Sound waves from a sound source drive a condencer microphone unit 18 arranged in front of a protector 16 to output an audio current to the primary winding T1 of a transformer T. Further, the sound waves from the sound source enter a case 11 through a hole 17 and oscillate an oscillation electrode 12. When the oscillation electrode 12 is oscillated, a conductive elastic body 15 of a coil spring fitting one end to an external electrode 14 is compressed and expanded. Since the conductive elastic substance 15 is formed by mixing carbon particles to silicon rubber, it has a good elasticity and a resistance value between both ends of the conductive elastic substance 15 is changed through the expansion and compression, and a current flowing between the external electrodes 13, 14 is changed according to the sound waves. As a result, the audio current flowing between the external electrodes 13, 14 flows to the primary winding T1 of the transformer T.

Abstract: PROBLEM TO BE SOLVED: To improve an alarm function by generating an alarm, when one of the output voltages of a pair of armature coils deviates from a specific value. SOLUTION: A comparator 44A in an alarm device 4A detects the output voltage of an armature coil 12 from among a pair of armature coils, and an output voltage generates L-level comparison output, when a comparison reference voltage is equal to or less than a comparison reference voltage VR2 and genertes H-level comparison output, when the comparison reference voltage VR2 is exceeded. Therefore, when the output voltage of the armature coil 12 decreases abnormally to the comparison reference voltage VR2 or lower, the comparison output of the comparator 44A goes to L level, and an L-level voltage signal is applied to an inverted input terminal (-).  Then, the comparison output of the comparator 44 turns to H level, an alarm output transistor 43 is turned on, and a display lamp 49 is driven so that it is turned on, thus alarming the abnormal decrease in the output voltage of the armature coil 12 and hence improving the reliability of an alarm function.
