Title: Connection structure of capacitor-run type single-phase induction motor
Inventor: UEDA MAKOTO
IPC: H02P23/00
Filed: 1984-03-12
Abstract: PURPOSE:To reduce noise due to the displacement of a current phase angle occurred when switching an induction motor from a high speed to a low speed by providing a switch for switching the speed between an auxiliary winding and a starting capacitor. CONSTITUTION:In a single phase induction motor having a main winding 1, an auxiliary winding 2 and a starting capacitor 3, a high speed terminal H is provided at the position where the number of turns of the winding 2 is most, a low speed terminal L is provided in the course of the winding 2 to switch the speeds via a speed changeover switch 4. In this case, even if the switch 4 is switched to a high speed terminal H or a low speed terminal L, the phases of the currents flowed to the main and auxiliary windings 1, 2 do not alter.

Title: Gas turbine blade
Inventor: NAKADA YUUJI
IPC: F01D5/18
Filed: 1984-03-13
Abstract: PURPOSE:To aim at enhancing the cooling capability of a blade, by causing cooling fluid discharged into the trailing edge section of a cooling air duct between the outer sheath of a hollow blade and an insert member inserted in the outer sheath to flow toward the leading edge section of the cooling air duct so that the cooling fluid is reversed in the leading end section and is then discharged from the trailing edge section. CONSTITUTION:A cooling air duct 14 is formed between the outer sheath 11 of a hollow blade and an insert member 12 fitted into the outer sheath 11. Further, cooling liquid which flows from the inside of the insert member 12 into the cooling air duct 14 through an air hole 17 in the trailing edge section of the outer sheath 11, is directed toward the leading edge section of the outer sheath 11. Therefore, cooling fluid is reversed in the leading edge section and is then discharged to the outside of the blade through an discharge air hole 18 in the trailing edge section. With this arrangement, cooling air of a substantially total flow amount passes along the entire section of the cooling air duct 14, thereby a satisfactory cooling effect of the blade may be obtained with a small cooling fluid.

Title: Scaffold circular corner connecting member
Inventor: FUJIKI FUMIO
IPC: E04G5/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent the tip part of a handrail material or cloth material from being protruded in a corner part to ensure the safety of a worker and to improve the appearance by arranging both ends of a scaffold circular corner connecting member having a circular form in two substantially orthogonal directions to form connecting parts, and setting the sectional form substantially constant over the whole length. SOLUTION: This scaffold circular corner connecting member has a circular form as the whole, both ends thereof are situated in two substantially orthogonal directions to form connecting parts 10, 20, and the sectional form is set substantially constant over the whole length. Each of the connecting parts 10, 20 is provided with a joint connecting hole 100, 200 and a pin 101, 201 crossing it in the diameter direction at the tip. When this scaffold circular corner connecting member is used, the tip part of a handrail material is never protruded in a corner part of a building since the handrail materials extended from two orthogonal directions are fixed to the connecting parts 10, 20, and the injure of a worker can be avoided. Further, since the connecting parts 10, 20 keep the same level, the orthogonal handrail materials to be connected connected can be horizontally arranged, so that no difference in level is produced, and the appearance can be enhanced.

Title: Storage container, manufacture of electron discharge element, and image forming device
Inventor: TOMITA YASUKO
IPC: B65D81/24
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To make a change in substrate surface energy difficult to occur during storage by constituting an internal surface of a container using a material with a volatilization quantity of organic compound at a normal temperature of a specific value or less. SOLUTION: An internal surface of a container 1 is constituted using a material whose volatilization quantity of organic compound at a normal temperature is 0.2 pg/s or less. Though the material with the volatilization quantity of organic compound at a normal temperature is not specifically limited, glass, metal particularly stainless steel, and ceramic may be preferably used. The storage container 1 having an internal surface constituted of such a member has an extremely small quantity of volatilization of an organic compound at a normal temperature, and a change in surface energy on a stored substrate is also small. Thus the storage container 1 which is inexpensive and simply structured and is free from a change in surface energy of a stored material can be obtained.  In addition, by providing a moving means such as a caster 2 on the container 1, the container can be smoothly transferred during each process or between respective processes.

Title: Torque limiter and permanent magnet rotary body
Inventor: FUJIOKA TERUO
IPC: F16D7/02
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To dispense with the thining of the thickness of a cylindrical permanent magnet and obtain a sufficient torque value by forming a recessed part on the permanent magnet adhesion part of a first rotary body main body and inserting a permanent magnet support member in the recessed part. SOLUTION: As a recessed part 18 is formed on the permanent magnet adhesion part 17 of a first rotary body main body 13 and a permanent magnet support member 14 is inserted in the recessed part 18, the outer diameter of the part inserted the permanent magnet support member 14 is not nearly enlarged for the outer diameter of the permanent magnet adhesion part 17. Therefore, when the first rotary body main body 13 made of synthetic resin is adhered to a cylindrical permanent magnet 3, it is nearly unnecessary to thin the thickness of the cylindrical permanent magnet 3, regardless of interposing the metal permanent magnet support member 14 on the adhered surface. This means that a torque value needs not be sacrificed, in such case that the space of the permanent magnet rotary body such as a torque limiter is limited.
