Title: Air cylinder
Inventor: YOSHIE JUNICHIRO
IPC: F15B15/14
Filed: 1991-10-08
Abstract: PURPOSE:To manufacture a small air cylinder by disposing a piston connected to a working rod within a cylinder having one air inlet hole at one end thereof and passing alternately compressed air and vacuum through the air inlet hole to reciprocate the piston. CONSTITUTION:A piston 8 is pushed by letting compressed air flow in from an inlet hole 10. Then, the piston 8 is returned to its original position by producing negative pressure in a tube 7 due to vacuum suction from the inlet hole 10. The piston 8 and a connecting rod 9 thus make reciprocating motion. The rod 9 is D cut to discharge the remaining air within the cylinder tube 7 and nullify the vacuum pressure to have communication to the atmosphere. The smooth reciprocating motion is thus attained. Then, as illustrated in the figure, by connecting the air cylinder to a vacuum source V and a compressed air source A through a two-way three-port type magnet valve 12 for vacuum and a magnet valve 13 for compressed air, the working vacuum can be obtained from energy consisting only of compressed air.

Title: Time base correction circuit
Inventor: MORI HISASHI
IPC: H04N5/956
Filed: 1991-10-08
Abstract: PURPOSE:To reduce the occurrence of time errors by using the same clock on both the writing and readout sides of a storage circuit and substituting the synchronization difference between the horizontal synchronizing signal on the writing side and a reference horizontal synchronizing signal for the readout address of the storage circuit. CONSTITUTION:A writing address generation circuit 4 generates a writing address 102 through a reference clock 110 by resetting a horizontal synchronizing signal 101. A difference detection circuit 6 detects the synchronization difference between a reference horizontal synchronizing signal 103 generated from a reference horizontal synchronizing signal generation circuit 7 and the signal 101 through the reference clock 110 and outputs a correcting signal 104. A readout address generation circuit 5 outputs a readout address 105 which is obtained by correcting the reference clock 110 with the correcting signal 104. Therefore, digital video signals 107 are stored in a storage circuit 2 through the writing address 102 or the signals 107 are read out from the circuit 2 through the readout address 105. The readout signals 107 are outputted as video signals 108.

Title: Sound arresting structure of engine control valve
Inventor: YAMANE SHUICHI
IPC: F02M69/32
Filed: 1990-09-28
Abstract: PURPOSE:To obviate the need of separate installation of a sound absorbing wall and reduce the number of parts by integrally molding the sound absorbing wall and a surge tank in an intake system through a partitioning wall and forming communication holes on the partitioning wall in order to permit the communication between the sound absorbing chamber on the sound absorbing wall and the tank chamber of the surge tank. CONSTITUTION:When a surge tank 4 is casted, a sound absorbing wall 12 for reducing the operation noise of an ISC valve 8 through a partitioning wall 10 is integrally molded on one side in the longitudinal direction. Further, on the partitioning wall 10, a communication passage hole 20 having a small sectional area of passage is formed for the communication between a tank chamber 16 and a sound absorbing chamber 18 consisting of the sound absorbing wall 12. The intake supplied into the engine flows into the tank chamber 16 from a throttle body 6 side and is supplied into the engine through an intake manifold 2. At this time, the abnormal noise during the operation of the ISC valve 8 can be reduced by reducing the pulsation due to the operation of the ISC valve 8 in the sound absorbing chamber 18. Accordingly, each number of bypass pipes and connecting clamps can be reduced in comparison with the conventional, since the surge tank 4 and the sound absorbing wall 12 12 are molded integrally.

Filed: 1994-10-25
Abstract: PURPOSE: To prevent a mulfunction of an internal circuit even if power voltage fluctuates. CONSTITUTION: A voltage fluctuation detection circuit 1 detects the voltage of a power line L. A main input buffer circuit 2 outputs an external input signal to the internal circuit. An input buffer circuit for fluctuation 4 outputs the external input signal to the internal circuit. The input buffer circuit 4 is set to a threshold voltage different from a threshold voltage in an inversion operation against the external input signal of the input buffer circuit 2. When the voltage of the power line L is fluctuated, a switch circuit 3 switches the input buffer circuit 2 to the input buffer circuit 4. Main output buffer circuits 5 output the output signal of the internal circuit to an external device. An output buffer circuit 7 for fluctuation is connected to a part of the output buffer circuits 5 in parallel and outputs the output signal of the internal circuit to the external device.  The operation speed of the output buffer circuit 7 is slower than that of the output buffer circuit 5. A switch circuit 6 switches the output buffer circuit 5 to the output buffer circuit 7 when the voltage of the power line L is fluctuated.

IPC: H01M2/02
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a lattice for a lead-acid battery having stabilized quality despite a fast production speed and an approximately uniform lifetime. SOLUTION: The lattice for a lead-acid battery has a tab 1A, and near its root, an upper frame rib 1B is provided with an elliptical recess 1D having a tapered surface of 90% deep-(A).
