Title: Sliding joint using coil spring
Inventor: KAWASAKI TOYOTOSHI
IPC: F16D7/02
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a sliding joint using a coil spring which generates no delay of rotation transmitting when the rotating direction is converted, by eliminating a clearance in the rotating direction of a locking part. SOLUTION: A pair of coil spring pieces 12a and 12b in which the locking part 16 is projected in the axial direction from one end 14a of a circular arc member 14 are superposed by making the winding directions of the circular arc members 14 reverse, and friction-abutted on the outer peripheral surface 32 of the first rotary member 30, while the locking parts 16 are superposed and locked to the locking groove 22 of the second rotary member 20 generating no clearance in the rotating direction. When a transmitting torque at a specific value or higher is operated between the first and the second rotary members 30 and 20, a slip is generated between the inner peripheral surface 15 of the circular arc member 14 and the outer peripheral surface 32 of the first rotary member 30.  Since the projection piece 16 is locked to the locking groove 22 of the second rotary member 20 generating no clearance in the rotating direction, no delay of rotation transmitting when the rotating direction is converted is generated.

Title: Communication controller
Inventor: HAZAMA RIYUU
IPC: H04L12/40
Filed: 1992-10-13
Abstract: PURPOSE:To eliminate the need for recognition of an address of communication destination by communicating a communication frame representing a connection request return when a logic port number and a line connection request key name are coincident. CONSTITUTION:When line connection is awaited, a service request means 1 makes a request of line connection comprising at least a logic port number, a line connection wait and a key name representing the line connection wait and stores information in a line connection buffer 2. A communication station going to make communication uses a broadcast means 3 to broadcast a communication frame representing a communication connection request on a communication line. The communication station of an opposite party receives a communication frame and a discrimination means 4 discriminates the coincidence between a line connection request key name and a logic port number stored in its own buffer means 2. When they are coincident with each other, a connection request means 5 sends a station address and a broadcast means permits a connection request and the communication is started. Then the line is connected without being conscious of the address of the opposite party.

Title: Sterilization using ultraviolet sterilizing lamp of spiral quartz pipe
Inventor: SATO MASAAKI
IPC: A61L2/10
Filed: 1991-07-25
Abstract: PURPOSE:To enhance sterilizing effect, to conserve space and to facilitate maintenance by forming a straight quartz tube for an ultraviolet sterilizing lamp into a spiral shape. CONSTITUTION:A quartz tube 1 is formed into a spiral shape and an ultraviolet sterilizing lamp 2 is arranged in the spiral quartz tube. In this case, the number of turns and caliber of the spiral quartz tube 1 and the number of the ultraviolet sterilizing lamps 2 are determined and set corresponding to treatment capacity. As a result, water is rotated within the spiral quartz tube and a flowing time of water is long and the emission angle of the ultraviolet sterilizing tube becomes 360 deg.. Therefore, the spiral quartz tube uniformly receives ultraviolet rays and sterilizing effect is high.

Title: Ink jet head cartridge and ink jet recording device equipped with the same cartridge
Inventor: EHATA TOKITAKA
IPC: B41J2/175
Filed: 1989-10-22
Abstract: PURPOSE:To make it possible to one use ink without holding it remaining in a tank by providing a projecting engagement part designed to engage with an ink absorber so that fill-in density is shown. CONSTITUTION:An ink absorber 51 consisting of a porous member or fibrous member is stored in a tank 13 which constitutes a cartridge C and is filled with ink. If a cartridge is given an impact or a vibration, ink discharge or an adverse effect on printing can be prevented. In addition, an atmospherically communicating hole 52b is provided on the top of a projecting part 52a installed on the upper surface of the tank. This hole 52 guides air from an atmosphere into the tank through an opening 13c on the top of the tank in accordance with a decrease in the residual ink amount in the tank. However, the surroundings of the atmospherically communicating hole 52 are maintained in a hermetically sealed state by water repellent member 53. Thus the ink can be prevented from flowing out of the tank through the hole 52. Consequently, even if the residual ink amount is at a low level, the ink in high density state flows to a supply side, so that it is possible to perform printing without any inconvenience.
