Patent JP-S5931228-A (JP)
Title: Automatic paper feeder
Inventor: OZAWA MASARU
IPC: B65H3/04
Filed: 1982-08-16
Abstract: PURPOSE:To enable a paper feeding table to be mounted in a horizontal state, resulting in reduction in an installation space, by bringing the uppermost paper of papers piled up on a paper feeding table into contact with the paper feeding belt of a clockwise-rotating belt mechanism by means of a forcibly pressed guide plate. CONSTITUTION:A clockwise-rotating mechanism 10 feeds an uppermost paper 1a of papers piled up on a paper feeding table 14 through rotation of a belt 13 with the aid of a pair of pulleys 11 and 12. A reversing roller 4 is brought into contact with the belt 13 from the under side of the clockwise-rotating belt mechanism 10 as the roller rotates, and prevents a second paper 1b from being fed accompanied by an uppermost paper 1a. In which case, a guide plate 16 is located to the forward end of the paper feeding table 14 in a manner to be rotatably supported by an axis 15, the plate being energized in a direction E around the axis 15 through the elastic force of a coil spring 17. This eliminates production of a biassing force exerted on the belt 13 under the own weight of a paper 1 through extremely tilting of the paper feeding table 14, and permits the paper feeding table 14 to be installed in a horizontal state.

Title: Mat made of synthetic resin
Inventor: UMIUCHI HIDEKAZU
IPC: E04F15/02
Filed: 1995-06-08
Abstract: PURPOSE: To check the engagement of a rod-shaped boy in a cylindrical body by setting up a spring piece to a fitting hole, mounting an engaging piece to the rod-shaped body and making the outside diameter of the rod-shaped body containing the engaging piece larger than the clearance of the fitting hole containing no spring piece. CONSTITUTION: Spring pieces 32 are projected and formed in the central directions on the internal surfaces of the fitting holes 31 of a unit board 2. Engaging pieces 41 are formed to the side faces of rod-shaped bodies 4, and the outside diameters of the rod-shaped bodies 4 comprising the engaging pieces 41 are made larger than the clearances of the fitting holes 31 containing no spring piece 32. Consequently, when the rod-shaped bodies 4 are pushed into the fitting holes 31 of cylindrical bodies 3, the engaging pieces 41 of the rod- shaped bodies 4 are passed while deforming the spring piece 32 sections of the fitting holes 31. When the engaging pieces 41 are passed, the spring pieces 32 are returned suddenly to an original state by elasticity, thus generating sounds. As a result, the unit boards 2 are connected.  Accordingly, connection is determined by generated sounds, thus preventing incomplete coupling.

Abstract: PURPOSE:To make it possible to wash fats and oils adhering to oil mists generated from a cooking stove, a table and the like by providing a flue having a nozzle for washing the inner wall of a suction port for use in a cooking stove and baffles, and putting a lid of an indoor ventilating suction port into a closed state in linkage with the stoppage of an exhaust fan. CONSTITUTION:When an indoor ventilating suction port 38 is closed, oil mists generated from materials being cooked are absorbed into a main body 20 through a suction port 23 for use in a cooking stove along an induction plate 21, and advance to an exhaust port while the direction thereof is being curved by baffles 25, 26 and 27. Meanwhile, the fats and oils come into collision with the baffles, the inner wall of the main body 20, and an exhaust fan, and adhere thereto. Thus, the fats and oils are removed. When a switch 46 is turned to the washing side (b), the fan 22 stops its operation, and power is supplied to a heater 43 of a tank 3, thus a detergent being heated. When a pump 31 is operated, the detergent is sprayed through nozzles 28 and 29 to wash the fats and oils adhering to the inner wall of the main body 20, baffles and the exhaust fan. Upon this occasion, the baffle 25 is closed by the gravity by the stoppage of the exhaust fan, and arms 34 and 35 rotate. When a lock claw 36 is released from a cutout 42, a lid 39 of a suction port 38 is closed by a force exerted by a spring 45.

Title: Information retrieval device
Inventor: UMEDA ARATA
IPC: G03B21/11
Filed: 1981-09-11
Abstract: PURPOSE:To improve operability by detecting and storing an end mark added to the final stage part of a microfilm, and giving an alarm when a frame or subject advance is to be made. CONSTITUTION:A start mark MS (used as a reset mark during rewinding) and an end mark ME are added to connection parts between the start and end stage parts of a microfilm 1 and leader tapes 1a and 1b. When the microfilm 1 is wound from a film reel until the end mark ME is detected, the detection of the end mark ME is stored in a storage device. In this state, if an operator tries to make a frame or subject advance of the microfilm, an erroneous operation signal is generated. Consequently, the microfilm 1 is rewound until the start mark MS is detected. Thus, operability is improved.

Abstract: PROBLEM TO BE SOLVED: To accurately mold revolving and stationary scrolls in a short time by providing a plurality of concentric circular grooves of rectangular section on the end plates of stationary and revolving scrolls on which spiral laps are not formed, and molding them by precision casting. SOLUTION: When a revolving scroll 1 formed to be combined together out of a spiral lap 2, a disc-like end plate 3, and a cylindrical boss 4 is manufactured by precision casting, a face 3b on which the boss 4 of the end plate 3 is formed (in other words, the opposite face to a face 3a formed with the lap 2) is formed with a plurality of concentric circular grooves of rectangular section. Consequently, shrinkage in the radial direction of the end plate face 3b on the boss 4 side is moderated, and hence falling of the lap 2 and warping of the end plate 3 are made small. That is, thermal shrinkage in the radial direction is balanced on both sides of the end plate 3, and the scroll can be accurately molded without falling of the lap.
