Title: Antifreezing rubber sheet
Inventor: HONDA TOSHIO
IPC: E01C5/18
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To prevent the freezing of a winter time road, sidewalk, roof, etc., in a cold temperature area. SOLUTION: A material is so formed that a crystalline substance or water absorption substance acting as a freezing mixture and having a melting point of 180 deg.C and water-soluble is compounded with a rubber composition constituted of a natural rubber, a synthetic rubber elastomer, a thermoplastic elastomer or a blend of them, and it is molded in the shape of a sheet or a mat and is vulcanized. Since the surface of the sheet or mat frozen with snow accumulated on the rubber composition sheet or mart reduces melting point of ice to approximately 20 deg.C by melting the crystalline substance (such as a small amount of sodium chloride) to the surface, the ice on the surface is changed into water, and frozen ice is easily separated from the rubber sheet.  Since a very small amount of crystalline substance contained in the sheet or met is continued to melt semipermanently, labor can be also reduced without excessively polluting environment by the present method for spreading a large amount of a snow- melting agent.

Title: Detection of focal position
Inventor: TOMIZAWA YUKIO
IPC: G02B7/28
Filed: 1983-03-01
Abstract: PURPOSE:To detect automatically the focal position of laser light for working by utilizing the focusing characteristic of the laser light in detecting the focal position of laser light for detection. CONSTITUTION:The light image 10 of laser light 6 for detection varies with the position of a working surface 9; the sectional area of the light image is smallest when the surface 9 exists in the focal position of a condenser lens 7 and the sectional area of the light image is larger than the min. value when the surface 9 exists above or below the focal position. The light image 10 of the laser light 6 is scanned by a photoelectric converting means 12 which can scan on a plane 11. The image obtd. by the scan is made into a binary coded image by a binary coding circuit 13, and the max. width thereof is detected by a max. width detecting circuit 14. A detecting circuit 15 for the focal position detects the min. value of the max. width row of the binary coded images obtd. by positioning successively a Z-table 17 and changing the position thereof, and outputs the position of the surface 9 in said time to an output terminal 101. The adjustment of the focal position is thus made possible by determining the position of the surface 9 by the table 17.

IPC: G11B3/085
Filed: 1982-03-04
Abstract: PURPOSE:To adjust the return position of a pickup easily by rotating an eccen- tric shaft inserted into the hole of a starting piece coupling with a rod to displace the rod, and to very the overall length of a starting plate. CONSTITUTION:When the bent part 26a of the rod 26 is engaged with the eccentric part 27a of the eccentric shaft 27 and a shaft part 32 is pressed into the hole 34 of the starting piece 33, a split groove 31 is contracted to allow a pawl paart 30 to pass through the hole 34, and when it comes out of the hole downwardly, the split groove 31 returns to its original state to fit a projection 29 in a knurl 35 by the elasticity of a thin projecting part 28. Then when a jig is inserted into an adjustment groove 37 made at the upper part of the eccentric shaft 27 and rotated, the eccentric shaft 27 rotates to displace the rod 26 in the arrow direction within the eccentricity size range of the eccentric part 27a. Thus, the overall length L of the starting plate is adjustable.

Title: Slow tracking control method and capstan motor intermittent drive control circuit
Inventor: HIROSE YOSHIKI
IPC: G11B15/467
Filed: 1992-02-20
Abstract: PURPOSE:To attain stable intermittent slow reproduction by deciding automatically a brake timing of slow reproduction so as to save trouble of every adjustment for each VTR set. CONSTITUTION:A magnetic tape is driven when a capstan motor 6 is started and an FG pulse (d) is outputted. The pulse is inputted to an FG pulse counter 2 and a speed control circuit 8 to control the drive of the motor 6. The counter 2 counts every input of the pulse (d) and the count is latched when a control pulse (e) recorded on the magnetic tape appears. As a result, an arithmetic circuit 3 delays the pulse by a time from the appearance of the pulse (e) and a pulse (c) is outputted to the motor 6 via a capstan motor driver 5 from a brake pulse generating circuit 4 to stop the motor 6. Thus, the tape feed quantity from the rising of the start pulse (b) till the appearance of the pulse (e) is made constant and a slow reproduction picture without noise is obtained.

Title: Arc length control in consumable electrode pulse arc welding
Inventor: DOU KOUGUN
IPC: B23K9/09
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To control the arc length without delay in real time even when the welding voltage instantaneous value detection signal is used as the feedback signal by surely and immediately returning to the center pulse frequency when the setting/detecting digital voltage difference becomes 0 so as to remove the filter of an arc voltage feedback circuit (detection welding voltage smooth circuit). SOLUTION: A center pulse period Tc is set corresponding to a wire supply speed setting value Ws. When a setting/detecting voltage difference ΔVd= Vs-Vd, namely the difference between an arc voltage setting value Vs and an arc voltage instantaneous value detecting value Vd is 0, a pulse period T is designed to be a center pulse period Tc. Further, after the start of welding, the pulse period T is increased/decreased from the center pulse period Tc according to the increase/decrease of the above-mentioned setting/detecting voltage difference ΔVd, so that a welding current average value Ia is increased/ decreased for returning the arc length.

Filed: 1987-02-17
Abstract: PURPOSE:To keep the surface temperature of a lamp constant by providing a means which changes the number of rotations of blades of a lamp cooling fan in accordance with the adjusting operation of the quantity of light of the lamp. CONSTITUTION:When an observer increases the quantity of light of a screen, the resistance of a light quantity adjusting volume 51 of the screen is reduced to change the input power of a lamp 4 and a lamp cooling fan 10, and the number of rotations of the lamp cooling fan 10 is increased in accordance with the rise of the wall surface temperature of the lamp 4, and the flow rate of air discharge is increased also. When the observer reduces the quantity of light of the screen, the resistance of the light quantity adjusting volume 51 of the screen rises to reduce the current flowing to the lamp 4 and the lamp cooling fan 10, and the flow rate of the lamp cooling fan 10 is reduced in accordance with the fall of the wall surface temperature of the lamp 4. Thus, the change of the wall surface temperature of the lamp due to the change of the quantity of light of the lamp is prevented to always keep this temperature constant.

Filed: 1978-03-25
Abstract: PURPOSE:To offer a container to store low-temp. liquefied gas safely and securely by providing a heat insulating layer inside the tank exterior structure and by installing a liquid reservoir tank in this shell with an appropriate space held between. CONSTITUTION:A side insulating layer 10 and a bottom insulating layer 11 are provided inside the tank's exterior structure composed of surface layer 9 of mild steel and an inside wall 12 of low-temp. keeping material. A tank proper 13 made of low-temp. keeping material. A tank proper 13 made of low-temp, keeping material is installed in this tank shell with an appropriate space between. The tank proper 13 is born by the tank shell's inside surface with the bearing layer 14 made of concrete interposed. Under such a storage condition that the tank 13 is filled with any liquid 15, temperatures of the tank 13 and the shell's inside wall 12 become nearly same. In case the tank proper 13 is damaged under the abovementioned condition, the liquid 15 which has flowed out of the tank 13, stays within the shell. Because the temp. of the shell's inside wall 12 and the tank 13 are nearly same, evaporated gas in not produced in a large quantity and therefore the pressure on the surface of tge shell's inside wall 12 will not rise up.
