Title: Multimedia communication device
Inventor: HIKITA FUJIO
IPC: H04L12/46
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To transmit and receive high-definition images or sound by performing transmission with a reliable TCP protocol parallelly with transmission with a UDP protocol from a transmitting side when a packet absence occurs. SOLUTION: When a receiving terminal 2 side can not receive a packet transmitted from a transmitting terminal 1, a UDP packet decomposing part detects it and a counter counts packets that can not be received. The transmission controlling part of the receiving terminal 2 monitors the counter all the times and notifies an absence information transmitting part of counter value as the number of absence packets at a certain fixed interval, and the absence information transmitting part transmits absence information to the transmitting terminal 1 side at appropriate timing. When the transmission controlling part recognizes that packet absence notified from the terminals 2 exceeds threshold, the transmitting terminal 1 side closes a SW, uses one RTP packet for two kinds of packets being a UDP packet and a TCP packet and transmits to the terminal 2 side.

Title: Window wiper in which electric stone is used and window wiper device for car, etc.
Inventor: KUBO TETSUJIRO
IPC: B60C5/00
Filed: 1990-11-29
Abstract: PURPOSE:To enable activation of washing water by a surface active effect so as to dispense with a conventional detergent or reduce the amount of its use remarkably by kneading electric stone (including electric stones in which electric stone base rock is contained) fine powder in a wiper blade. CONSTITUTION:A powder of high molecular compound or natural fiber 13 in which electric stone fine powder 12 is kneaded is kneaded in a wiper blade 11 of a window wiper. The wiper blade 11, when the window screen, etc., of cars, etc., is washed by water, activates the washing water by surface active action of the electric stone fine powder to help the washing. Namely, since electrical insulation is made by insulation material between the electric stone fine powder particles, electrodes of each fine powder are not counteracted to each other and electrode reaction is made between each of the electric stone fine electrodes and the water to produce surface activity in the water. Thus stain such as oil film, etc., can be washed without using conventional washing liquid.

IPC: G01M99/00
Filed: 1990-11-29
Abstract: PURPOSE:To uniformly detect a defect over a wide measurement range without using a fluid such as oil by feeding an acoustic wave signal to an acoustic generator, pressing it to the surface of a tested structure, and detecting the structural change. CONSTITUTION:An acoustic wave signal is fed to an acoustic generator 20 from signal generator 11, the generator 20 is pressed to a tested structure 30 with a constant pressure and closely stuck on the surface, the acoustic wave vibrates the structure 30, and the moving coil impedance of the generator 20 is changed by the vibration state. When the airtightness between the structure 30 and the generator 20 is kept constant, the same change is detected for the same tested structure, the impedance change is phase-detected by a phase detec tor 12 at the same frequency as that of the signal generator 11, it is then ampli fied by an amplifier 13, the noise signal other than the acoustic change signal is cancelled by a signal processor 14, it is displayed on an X-Y recorder 15, thus the position and size of a cavity section 21 of the structure 30 difficult to detect can be detected.

IPC: H04N5/44
Filed: 1990-11-29
Abstract: PURPOSE:To save a power by connecting the power source of an interlocking power source outlet by turning on an extension switch and selecting an audio visual input terminal, and setting a power source for external connection equipment connected to the outlet only when it is required. CONSTITUTION:When toll BS broadcast received with a BS tuner 11 is outputted in a scrambled state and is inputted to a decoder 30, it is descrambled by the decoder, and is inputted to a second AV input terminal 20, and is fetched in and reproduced by a signal processing circuit 13. In such a state, the power source is supplied to the decoder 30 only when the second AV input terminal 20 is selected i.e. the decoder 30 is required by turning on the extension switch 17, and the power source of the decoder is disconnected in other cases. Therefore, the connection/disconnection of the power source of the decoder 30 can be performed without necessitating a specific operation, which prevents wasteful power consumption from occurring.

IPC: H01L21/302
Filed: 1987-12-24
Abstract: PURPOSE:To rapidly reduce the influence of a step, to flatten the bottom of a worked hole, and to improve its working yield by recognizing in advance the position of the step if there is the step in a range to be worked, working a high region of the step as a former stage of working as a ridge, and then primarily working a predetermined range. CONSTITUTION:Before a material to be worked with a step disposed at one side is worked at an original range to be worked (width W1, depth d1), a high range C of the step is set as a range to be worked (width W2, depth d2) as a former stage of working, and worked until it becomes the same height as that of the lower part B of the step, i.e., to the depth d2 (in which the bottom 50' of the hole by the former stage of working). At this stage, a roof P remains at the position of the initial step. Then, the range to be worked is reset at an original range to be worked, and started to be worked. As the working is advanced, the sidewalls of the roof are eroded from both sides, and eliminated at an early stage. Thereafter, its flat face is progressively worked, and the bottom 50 of the hole to be worked is eventually flattened.

Abstract: PURPOSE:To reduce the cost of a transcription device by forming the diameters of corona generating fine lines so that the one most down-stream of the array is smaller than the one most up-stream, and also that the down stream side ones are not larger in diameter than the up-stream side ones. CONSTITUTION:The diameters of corona wires 15B, 15C, 15M, 15Y, of transcrip tion chargers 7B, 7C, 7M, 7Y of the title device are different. That is, the respec tive diameters dB, dC, dM, dY, have the relationship of dB>dC<dM<dY. The voltage required for a corona discharge have a correlation with the diameter of the corona wire, and by making the diameter of the corona wire smaller, the voltage required for the corona discharge can be lowered. Thus, the inconve nience of having to increase the voltage impressed to the corona wires placed down stream can be solved, the actual electric field of actual transcription can be made equivalent even when the same power source is used, and a tran scription can be made in a good condition.

Title: Check valve
Inventor: HIOKI TOSHIMICHI
IPC: F16K15/04
Filed: 1989-12-14
Abstract: PURPOSE:To suppress generation of turbulence and collision or the like of a ball valve unit against a flow path internal wall, at the time of circulation of fluid, so as to prevent genera tion of noise by arranging the ball valve unit, which opens and closes a circulation path, and a cushion member, for holding a contact condition with a valve seat internal wall, in the downstream side of the valve unit, between the valve seat and a compression spring which are respectively provided in the upstream and downstream sides. CONSTITUTION:When a pressure of compressed air A is increased to not less than a predeter mined value, a ball valve unit 13 is detached from an O ring 5 against urging force of a compression coil spring 11. Now because a spherical cushion member 14 is interposed between the valve unit 13 and the spring 11, the pressure of the air A and the urging force of the spring 11 are applied to act on the valve unit 13. As a result, the valve unit 13 is brought into contact with an internal wall of a valve chamber 10, and the cushion member 14 is adapted to an internal wall of a valve seat 10. Here by positioning the cushion member 14 in the vicinity of the downstream of the valve unit 13 to hold a contact condition with the internal wall of the valve seat 10, the valve unit 13, when it is detached from the O ring 5, can be prevented from colliding against an internal wall of a circulation path B by vibration of the valve unit 13. And also, generation of turbulence such as Karman's vortex by the air A is suppressed by existence of the cushion member 14.
