Inventor: KITSUKAWA MOTOHIKO
IPC: F15B15/24
Filed: 1985-03-29
Abstract: PURPOSE:To prevent generation of an inoperative region on the way of change in a compound length, by preferentially driving a cylinder in the front stage to a cylinder in the rear stage under a condition that the cylinder is successively actuated from a side of the rearmost stage, when the cylinder is set to a large length. CONSTITUTION:A rod of each cylinder 15-19 connected in series is set to a stroke successively larger in every predetermined proportion over stages from the front to the rear. While a device, when the cylinder is set to a large length, preferentially drives the cylinder in the front stage to the cylinder in the rear stage in a condition that the cylinder is successively driven from a side of the rearmost stage. Further the device, when the rods of the plural cylinders are driven in an equal direction, provides operation timing of an optional cylinder being different from that of the other cylinder. By this constitution, the device prevents a change in a reverse direction to the change direction while an inoperative region from being generated on the way of change in a compound length.

Abstract: PROBLEM TO BE SOLVED: To always obtain an excellent image by controlling the driving amount of a correction means such as a variable apex angle prism or a shift lens by utilizing the focal distance information of a photographing lens when image blurring is corrected by the correction means. SOLUTION: By a VAP control means 123, the prism apex angle of the variable apex angle prism 105 is obtained based on a focal distance signal as to the photographing lens from a focal distance detection circuit 112 and a deflection signal from an angular velocity sensor. Besides, the displacement amount of the prism apex angle is generated based on the present prism apex angle of the prism 105 from an apex angle sensor 112. Then, a motor 121 is driven so as to change the prism apex angle of the prism 105. Besides, the driving amount of the correction means such as the prism 105 for correcting the image blurring is controlled so as to be made larger when the focal distance of a photographing system is long in comparison with a case that the focal distance thereof is short with respect to a fixed signal from a deflection detection means 301.

Abstract: PURPOSE:To improve the charging efficiency of fresh air and to prevent the occurrence of a fluctuation in an air-fuel ratio in a combustion chamber, by a method wherein an auxiliary air passage is connected to the portion, located in the vicinity of a combustion chamber, or an exhaust passage, and a check valve and an on-off valve, opened and closed in linkage with a crank shaft, are situated in the passage. CONSTITUTION:When a crank shaft 6 is rotated and a piston 3 is raised, fuel-air mixture is sucked in a crank chamber 8a through an intake air passage 11. Meanwhile, when a piston 3 is lowered, fuel-air mixture in the crank chamber 8a is extruded in a combustion chamber 5, gas, being burnt during a preceding stroke and present therein, is extruded in an exhaust passage 12 to replace the burnt gas with the fuel-air mixture.

Title: Mold for molding thermosetting resin

IPC: B29C45/26
Filed: 1989-03-20
Abstract: PURPOSE:To contrive to uniformize resistance to flows of filling resin in respective cavities at the final pressurizing and consequently facilitate the setting of the conditions at the final pressurizing and reduce the generation of voids by a method wherein the nearer the positions at which the cavity connects to a runner, are to a pot, the larger the opening areas of the vents of the respective cavities become. CONSTITUTION:Thermosetting resin 5, which is shaped in the form of a tablet, is charged in a pot 4 and melted by heating and pressurized with a plunger 3. The molten resin 5 is fed through runners 6 and respective gates 7 and filled in respective cavities so as to be molded in the form of lead frames. The nearer the opening sites of the vents 9 of the respective cavities 8 are to the pot 4, the larger the opening areas of the vents 9 of the respective cavities 8 are made. Concretely, since the area of the vent 9 of the cavity, the resistance of which to the flow of resin is larger during the proceeding of the setting of filling resin, is set larger, the sum of the resistance due to the setting resin and the resistance at the vent 9 becomes nearly the same at the respective cavities 8 and consequently the amount of resin discharged from the vent 9 becomes nearly the same at the respective vents, resulting in allowing to reduce defects due to the generation of voids.

IPC: B42D9/00
Filed: 1994-02-24
Abstract: PURPOSE:To hold a book open intactly by employing a few clips connected through a rod, and securing both ends of the two-page spread of a book by each clip. CONSTITUTION:Both ends of the two-page spread of a book 3 are secured by each clip 1, and the clips at both ends are connected through a rod in order not to make the book closed. Thus, by securing both the ends of right and left pages with each clip, they do not fall down therefrom irrespective of the thickness of right and left pages. Also, since both the ends of the books are held by the clips 1, an obstructed part of view of the book 3 can be avoided. In addition, it is relatively simple structure, so that the transportation of the unit can be done with ease. By changing the length and shape of the rod 2, control of the length of the rod 2, the movement of the clips 1 on the rods 2, and the size and shape of the clips 1, it can correspond to the size and thickness of the book 3. Warpage is applied on the rod in the direction opposite to closing forces of the book, thereby inhibiting the book from closing positively.

Title: Holding pickup system
Inventor: YAMADA MASAYOSHI
IPC: H04M3/42
Filed: 1982-04-21
Abstract: PURPOSE:To improve service to an incoming call, by dialing a special number after holding a call temporarily while the extension is in service, and making a connection for answering to an incoming call to another extension. CONSTITUTION:Extensions C and D are engaged with each other through a trunk IOT. At this time, a junction line trunk PVT terminates and when an extension A is placed in a calling state, the hooking of the extension C allows a central controller CC to starts a call-back connecting mechanism CBC, connecting the extension C to an oscillating register trunk OCT. The extension C selects the special number for making a request for interception after receiving a tone from the trunk ORT. The mechanism CBC discriminates it to start a pickup mechanism PUC, reporting that. The mechanism PUC detects the extension A in service in the same extension group with the extension C to set a channel in a network NW, making a connection between the trunk PVT and extension C. Consequently, the extension C answers to the trunk PVT as a substitute for the extension A in absent state.
