Title: Terminal member for connecting optical fiber
Inventor: ANDO YASUHIRO
IPC: G02B6/38
Filed: 1984-09-05
Abstract: PURPOSE:To expand the degree of freedom allowing precise positioning at a connection point and to prevent an optical fiber connecting terminal member from damage even if slight deformation is generated by setting up the length and outer diameter of the terminal member to a specific relation so that the cylindrical part of the member is elastically deformed. CONSTITUTION:In the optical fiber connecting terminal member (ferrule) 1' having the cylindrical part having high circularness and accurately forming a through hole 6' slightly larger than the outer diameter of an optical fiber, L<2>/D is set up to 2.4 times or more the value of Ef/Sf when the outer diameter and length of the member 1' are D and L respectively and its Young's modulus and yield stress are Ef and Sf so that said cylindrical part is elastically deformed. In addition, a synthetic resin mold containing reinforcing agents such as glass fiber or carbon fiber is used for the terminal member 1'. Since the terminal member 1' having high elasticity is used, the production cost can be reduced by using plastic without requiring high accuracy. In addition, working at the operation of a connector is made easy and the optical fiver connecting method using the elasticity can be applied. For instance, an economical optical connector can be obtained by using a V-shaped rgoove.

Title: Control unit for pneumatic type automatic clutch
Inventor: YAMAMURO JIYUUMEI
IPC: B60W10/10
Filed: 1982-10-22
Abstract: PURPOSE:To reduce required space and eliminate the need for a rotary sealing section so as to make an automatic clutch compact by adjusting the input rotary speed signal oil pressure detected by means of a pitot tube to the start pressure by means of a starting valve and supplying it. CONSTITUTION:While a vehicle is starting, the force of a sring 208, the start adjusting pressure that is actuated on the area difference between lands 206b and 206c and the start pressure that is actuated on a land 206a are applied rightward and the engine speed signal oil pressure that is actuated on the area difference between the lands 206c and 206d is applied leftward to the spool 206 of a starting valve 116. Since the spring pressure and the start adjusting pressure are maintained constant, the start pressure is controlled so as to be counterbalanced by the engine speed signal pressure. When the start pressure is supplied to a clutch 36 for advance through a manual valve 104 and the engine speed exceeds the preset one, the clutch is engaged smoothly. That is, the need for a centrifugal valve and a rotary seal that require large space can be eliminated by adjusting the oil pressure detected by means of a low pressure pitot tube with a little amount of oil.

Title: Diagnostic adjusting method for tape loop position detector
Inventor: OOMORI SUSUMU
IPC: G11B15/58
Filed: 1980-12-25
Abstract: PURPOSE:To diagnose and adjust the tape loop position automatically, by providing a displacement controller with a capstan motor, displacing the tape loop in a vacuum column for a specified amount automatically and comparing and adjusting the output change in the tape loop position detector with a preset reference value. CONSTITUTION:Even if a tape loop is displaced through a driven capstan motor 5, a reel motor is stopped with a reel brake so that it does not move, and the tape loop is moved by turning the motor 5 clockwise or counterclockwise. Since the tape must be made run by Lcm to move the tape loop by L/2cm, thus it can be done by stopping the motor 5 at a calculated count, and the displacement of the tape loop can automatically be controlled by counting the output pulse of a displacement controller 10.

Title: Method for adsorption and separation of air
Inventor: AMITANI TATSUO
IPC: B01D53/04
Filed: 1980-12-25
Abstract: PURPOSE: To prevent the decrease in the concn. of O 2  which is a desorbed gas and the decrease in the yield of O 2  by withdrawing air from both of the supply side and N 2  removal side of an adsorption tower and decompressing the inside of the tower at the time of start of desorption in separating air to N 2  and O 2 .  
     CONSTITUTION: At the stage of performing a desorption process in an adsorption tower 2, valves 15, 40 are opened to allow the pressurized air in the tower 2 to flow out through manifold pipes 5, 6 on both sides and to decompress the inside of the tower 2 down to prescribed pressure. Thence, the valves 15, 40 are closed and a valve 17 is opened to withdraw the gas in the tower 2 through a gaseous O 2  delivery main 33 and a delivery pipe 18 and to decompress the tower inside further, thereby allowing the O 2  adsorbed on an adsorbent to desorb. After the desorbed gas is delivered out, the valve 17 is closed, and valves 36, 25 are opened to conduct part of the pressurized gaseous N 2  in a gaseous N 2  delivery main 35 into the tower 2, thereby boosting the tower 2 inside. According to this method, the flowing of the air during the outflow of the air is less and the partial pressure of the gaseous O 2  does not drop. Hence, the concn. of the O 2  is high and the gas of much volume is obtained.

Abstract: PURPOSE:To improve a switching delay when a solid-state element relay is turned off by speedily discharging a gate capacity by inserting an NPN transistor whose (k) parameter kFE is high into the gate and source of an MOS transistor(TR), and to reduce a switching noise by turning the NPN transistor into a chip. CONSTITUTION:When a photodiode array PDA is irradiated with an optical signal and the solid-state element relay is turned on, a capacity between the gate and source of an MOS TR 20 is charged by currents from a constant current. Then, when an element relay is turned off, the charged currents are supplied through a resistor 32 and an NPN TR 31 is operated. At that time, the NPN TR 31 whose (k) parameter kFE is high is used as the NPN TR 31, so that the capacity between the gate and source of the MOS TR 20 can be speedily discharged and the switching relay when the solid-state element relay is turned off can be improved. Also, the switching noise when the solid- state element relay is turned on/off can be reduced by integrally turning the NPN TR 31, diode 30 and resistor 32 into the chip.

Title: Inspecting method for viscous coupling
Inventor: BETSUSHIYO NORIAKI
IPC: G01M13/02
Filed: 1990-07-13
Abstract: PURPOSE:To shorten inspecting time by providing a middle mode between the first measuring mode and the second measuring mode, and rising an oil temperature to a fixed value below the upper limit of the allowable oil temperature range of the second measuring mode. CONSTITUTION:In the first measuring mode, for instance, after motor is early driven at 60rpm of the number of revolutions to rise oil temperature to 35 deg.C, the number of revolutions is continuously risen to 120rpm, and the value of torque at the time of 80 deg.C of the oil temperature is measured to stop a driving motor. In a middle mode, for instance, the motor is driven at 90rpm of the number of revolutions until the oil temperature attains the temperature range from 120 to 180 deg.C. Namely, the above oil temperature range is established below 180 deg.C which is the upper limit of an allowable oil temperature range(140-180 deg.C) in the second measuring mode, and in the case where the above oil temperature range is denoted in the value of torque, it is the range at the time when the torque becomes about 25kgm. In addition to that, a temperature gradient at this time is steeper in comparison with that obtained by an ordinary method, and the temperature rises efficiently. The second measuring mode is inspected at 60rpm of the number of revolutions.
