Title: Video tape recorder
Inventor: KAWAKAMI KOICHI
IPC: H04N5/915
Filed: 1993-03-18
Abstract: PURPOSE:To prevent occurrence of noise by changing either of both heads having the same or the different azimuth angle from that of a track reproduction head for each prescribed revolution from a start point of a track on which a control signal is detected. CONSTITUTION:A magnetic tape is reproduced, on which an extracted video signal of one field in three fields is recorded by a different azimuth angle in one track and a control(Co) signal is recorded. In this case, A Co head 72 and a Co signal detection circuit 73 output a Co signal and a PG detection coil 75 and rotary phase detection and switching pulse(SP) generating circuits 76,77 output a switching pulse SP. A switch 60 changes alternately outputs of heads A+, B- and A-, B+ whose different azimuth angles +, - are close to each other by the SP at each half revolution of a rotary cylinder 7. Then a switch 70 changes the output of the switch 60 for each prescribed number of revolutions under the control of a microcomputer 74 receiving the Co signal and a video signal processing circuit 71 reproduces the selected signal and outputs the reproduced signal. Thus, production of noise is prevented.

Title: Connecton method of optical fiber
Inventor: KASHIMA GIYUU
IPC: G02B6/24
Filed: 1981-04-18
Abstract: PURPOSE:To automate the start of melting and to make the characteristics after melting uniform by monitoring the optical output inputted from one optical fiber and outputted to another fiber in case of molten connection of the optical fibers arranged on a straight line. CONSTITUTION:In case of molten connection of optical fibers 14, 24 arranged on a straight line in V-shape grooves 12 and 22, the interval between these fibers before melting, for example <=0.4mm., is found from a test so that the connection loss after melting is included within an allowable value. Then light is made incident from one end of the fiber 14 and emitted from the fiber 24 and these fibers 14 and 24 are allowed to approach at a constant speed; at the time, the coefficient of variation on emitted light strength is fixed in correspondence with the interval between these fibers, 0.04mm.. The fibers 14 and 24 are sampled on the basis of the strength of outputted light and set up automatically so that melting is started when the prescribed variation of strength is obtained. Since the coefficient of variation on the strength of emitted light is used, uniform adhesive characteristics can be obtained even if the length of fibers is changed.

Title: Container with antibacterial property and its manufacture
Inventor: UMEYAMA HIROSHI
IPC: C08L23/10
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To eliminate decomposition of antibacterial agent even in a container using resin having high melting temperature by heating a preform provided with an OP agent layer containing the antibacterial agent on an outer surface of the preform, and orientation blow molding it, thereby thinning the OF agent layer. SOLUTION: A preform 2 is coated on its surface with an OP agent solution 8 containing antibacterial agent to obtain a preform 3 having an OP agent layer containing the antibacterial agent. The preform 3 is orientation blow molded by a normal orientation blow molding machine. First, the preform 3 having the OP agent layer is heated by an infrared heater or contact heating. Thus, a surface temperature of a body 7 with a bottom is raised, for example, to 100 to 150 deg.C, and then slowly cooled. In the case of PET resin, it is lowered to an orientation temperature of, for example, 70 to 100 deg.C, thereby making the temperature distribution of the body 7 uniform. Thereafter, an orientation rod and compressed air are used together to be orientation blow molded.

Filed: 1994-03-30
Abstract: PURPOSE: To reduce the change in air-fuel mixture composition as much as possible in a case of changing air flow rate passing through an intake tube of an internal combustion engine in venting a tank. CONSTITUTION: A tank-venting apparatus 17 connected to an intake tube 11 of an internal combustion engine 10 is controlled via a tank vent valve 18. Respective volume flow rates of vent gas transferred from the tank-venting apparatus to the intake tube are set according to respective practical operating states of the internal combustion engine. The respective set volume flow rates are set by driving the tank vent valve to a prescribed state. An adaptive correction coefficient (dte) is formed using an air-fuel mixture controller 21 and the adaptive correction coefficient is changed in the direction for changing the volume flow rate, when reducing the volume flow rates respectively. This constitution can reduce the change in the air-fuel mixture composition, even if changing the volume flow rate of the vent gas.
