Title: Belt carrying device
Inventor: HOKARI NORIO
IPC: G03G21/14
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To detect average speed variation of a whole belt without nipping a belt by arranging a speed detecting roll at a position a specific distance apart from a belt driving roll. SOLUTION: An intermediate transfer belt B is transported through a primary transfer region Q3 in which a toner image on the surface of an image carrier body 16 is primary-transferred on the surface of a belt B and a secondary transfer region Q4, in which a toner image primary-transferred on the surface of the belt B is secondary-transferred on a recording sheet S. A belt driving roll 26 and a speed detecting roll ER are arranged interposing the primary transfer region Q3 between them. The speed detecting roll ER and the belt driving roll 26 are arranged apart from each other by >= a quarter of circuit length of the belt B. Thereby, the speed detecting roll ER can detect averaged speed of the belt B without being affected by speed variation of the belt B caused at an adjacent position of the belt driving roll 26.

Title: Running direction reversing circuit for tape recorder
Inventor: YAMANAKA SUSUMU
IPC: G11B15/08
Filed: 1985-12-24
Abstract: PURPOSE:To reverse the running direction of a reader tape by constituting the titled circuit of a transistor (TR) whose base and emitter are applied with a voltage extracted at the 1st and 2nd conductor paths and a reversing plunger controlled by the TR. CONSTITUTION:A ray lighted by a light emitting diode 2 is reflected in the surface of an opaque leader tape and the luminous quantity is more than the luminous quantity reflected on the surface of a magnetic tape. Thus, the voltage detected by a photo TR 3 and the voltage extracted to the 1st conduction path 10 are increased to increase the base voltage of the 1st TR 17. However, the time constant of the 2nd conductor path 11 is large, since the extracted voltage is not risen immediately, the base and emitter of the 1st TR 17 are forward- biased tentatively, the 1st TR 17 is turned on and the 2nd TR 18 is turned off. Thus, the reverse plunger 19 is energized and the tape running direction is reversed immediately.

Title: Gas separation method
Inventor: YOKAWA SHINTAROU
IPC: B01D53/22
Filed: 1986-12-09
Abstract: PURPOSE:To increase separation rate of a gas separating membrane, by ionizing mixed gas and increasing the concentration of a substance to be separated on the surface of the gas separating membrane. CONSTITUTION:The gas separation method is carried out by a gas separating membrane 17 and a device with an ionization device with an electrode, close to the gas separating membrane 17, consisting of an electric discharge pole 21 and a grounding pole 19, to which voltage is applied. When negative voltage is applied to an electric source for discharging 23, corona discharge is generated between the electric discharge pole 21 and the grounding pole 19 to ionize the gas around the electric discharge pole 21. At that time, in case of a substance with much of electronic affinity and easily converting into negative ion, for instance, air constituted with a mixture of oxygen and nitrogen, oxygen is selectively ionized. The ionized oxygen monocules charged as negative are attracted to the grounding pole 19 by static to increase highly the oxygen concentration around the surface of the gas separating membrane 17 and also increase separation rate to a great extent.

Title: Method for detecting eye-mark on container
Inventor: USHIYAMA HARUO
IPC: A23C9/12
Filed: 1992-10-30
Abstract: PURPOSE:To correctly detect an eye-mark position of a container even if the container has shifted in a mounted position by detecting the eye-mark attached to the container and measuring the position of the eye-mark. CONSTITUTION:An eating jig held by a straw attaching turret and surrounded by a film is correctly controlled to a relative position to a container C. Thus when the container C mounted on an eye-turret is rotated by a stepping motor and an eye-mark of the container C is detected by a photoelectric tube 60, the motor stops. The photoelectric tube 60 includes a light emitting element 62 and a light receiving element 64, wherein the light emitting element 62 applies a light beam L, and the light receiving element 64 receives reflected light and generates an output OP-1. The output OP-1 drops when the eye-mark is detected. By amplifying the output OP-1, inputting its signal OP-2 to a differentiator 70 and taking out only a signal which has rapidly changed to a negative side, an output OP-3 is obtained and determined by a level determining means 72, thereby stopping the motor.
