Title: Method for forming coated film of tin or tin-based alloy on inner surface of metallic pipe
Inventor: SUGIYAMA MOTOHARU
IPC: C23C18/31
Filed: 1986-10-27
Abstract: PURPOSE:To easily form a uniform corrosion-resistant coated film without using a complicated device by coating a thin tin plated film on the inside of a metallic pipe wherein a copper phase is formed, inserting a film forming metallic wire rod consisting of tin, and heating the material under specified conditions to form a tin coated film on the inner surface of the metallic pipe. CONSTITUTION:A chemical tin plating soln. is injected into the metallic pipe, wherein a copper phase is formed at least on the inner surface, and circulated, with plating carried out at about 60-85 deg.C for about 10-30sec, and a thin tin plated film having about 0.5mu thickness is formed by substitution for the copper phase. The film forming metallic wire rod consisting of tin or a tin-based alloy is then inserted into the metallic pipe, the material is heated at a temp. above the m.p. of the wire rod, preferably at about 900-1,100 deg.C, for about 30-120sec, hence the tin plated film is melted, and the wire rod is simultaneously melted and spread. As a result, the uniform coated film of tin or a tin-based alloy is easily formed on the inner surface of the metaallic pipe, and the process can be effectively applied to a thin dia. and long-sized pipe material.

Filed: 1992-08-31
Abstract: PURPOSE:To reduce the entropy per information source symbol by transmitting the information data including a prescribed matrix equivalent to a single block after rearranging the data into a serial information data and inversely scanning this data to rearrange it into a prescribed matrix. CONSTITUTION:The input image data S1 undergoes an orthogonal transformation through a two-dimensional DCT circuit 2 and then is quantized by a quantizing circuit 3. The quantized DCT coefficient data C2 received from the circuit 3 is inputted to the scanning circuits 4A-4C respectively. The circuits 4A-4C turns the data C2 into the run length and input them to a selector circuit 5 as the two-dimensional series data RA1-RA3. At the same time, the EOB symbols EOB1-EOB3 are inputted to a comparator 6. The comparator 6 transmits the scan pattern data STD of the largest 0 run length. Thus the circuit 5 selects one of data RA1-RA3 and inputs it to a variable length coding circuit 8. A multiplexing circuit 7 turns the data RA0 into an entropy code, and the entropy code is multiplexed together with the data STD.

Title: Ozone water producing apparatus
Inventor: AMAKUSA MITSUGI
IPC: B01F1/00
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To provide an ozone water producing apparatus which does not allow air mixed with ozone to be ejected from a jet nozzle through a discharge opening even when the apparatus is installed at a high position to be used. SOLUTION: When an apparatus is used at a position to make a jet nozzle 22 lower than a discharge opening 4, since an excess ozone separator 2 is opened to the atmosphere through an ozone decomposing apparatus 10, with water head pressure from the discharge opening 4 to the surface of water in an ozone dissolving water tank applied, the amount of ozone water ejected from the nozzle 22 becomes larger than the amount of supplied city water. The increase in the flow velocity of ozone water flowing in a discharge pipe 17 creates negative pressure so that a check valve is opened to introduce the atmosphere from a pipe 19. Consequently, the fluid of a mixture of ozone water and air flows toward the nozzle 22, the outflow from the tank 5 is controlled to prevent air directly mixed with ozone from being ejected from the nozzle 22 through the discharge pipe 17.

Abstract: PURPOSE:To control a sense of direction of a sound image independently of a listening position by controlling a phase characteristic of plural phase shifters so that a synthesized wave front of a reproduced sound of all speakers is independent of its frequency but depending on an angle inputted to a wave front angle input means. CONSTITUTION:A phase characteristic controller controls the phase characteristic of plural phase shifters 104-106 based on a wave front angle inputted to a wave front angle input means 101. Then plural speakers 107-109 arranged at a predetermined position reproduce outputs of the phase shifters 104-106. In this case, the phase characteristic controller controls the phase characteristic so that the synthesized wave front of the reproduced sound from all the speakers 107-109 is independent of the frequency but depending on an angle inputted to the wave front angle input means 101. thus, a listener receives an impression as if sound were radiated from a direction of wave front and the sense of direction is controlled.

Title: Motor rotation control system
Inventor: HIRATSUKA YOSHIAKI
IPC: H02P7/29
Filed: 1988-10-12
Abstract: PURPOSE:To reduce noise, to decrease irregularities in the rotating speed of a fan and to enhance its efficiency by controlling a current returned to a coil by switch means to increase or decrease a counterelectromotive force generated in the coil, and controlling the torque of a motor. CONSTITUTION:A speed switching signal RS is output at a high level at the time of high temperature to turn ON a Tr 4, a low level voltage dropped by a resistor R1 is input to turn OFF a Tr 3. When a Tr 1 or Tr 2 is turned OFF, large currents flow due to counterelectromotive forces induced in coils L1 and L2, and a motor rotates at a high speed. The signal RS is output at a low level at the time of ordinary temperature to turn OFF the Tr 4, and the Tr 3 inputs a high level voltage to be turned ON. When the Tr 1 or Tr 2 is turned OFF, a current determined by the Zener voltages of Zener diodes Dz1 and Dz2 of the current determined by a counterelectromotive force induced in the coil L1 or L2 is returned through the Dz2 to the coil L1 or L2 to reduce the counterelectromotive force, thereby reducing the rotating speed of the motor.
