Patent JP-S61106918-A (JP)
Title: Intake-air control device in engine
Inventor: KONO MASAKIMI
IPC: F02B29/08
Filed: 1984-10-30
Abstract: PURPOSE:To obtain a high output power, in a Miller cycle engine, by changing the timing of opening and closing of a timing valve upon high load and high rotational speed operation so that the engine is operated as a normal Otto cycle engine to enhance the charging efficiency. CONSTITUTION:Each engine cylinder incorporates with two intake valves 12a, 12b, and the intake valve 12a is provided with a rotary type timing valve 24 which opens upon termination of suction stroke to perform adiabatic expansion so that the engine operates as a Miller cycle engine. The opening and closing timing of the timing valve 24 is controlled by a control device 71 through a shaft phase adjusting means 26 composed of inclined teeth between the shaft 39 of a valve drive pulley 27 and rotary shaft 38 of the valve. When a high load and high rotional speed operation of the engine is detected, the control device 71 sets the opening and closing timing of the timing valve to be made to be substantially equal to that of the intake valve 12a so that it apparently establish a condition in which no timing valve is provided, and therefore, the engine is operated as an Otto cycle engine.

Filed: 1987-09-14
Abstract: PURPOSE:To prevent dust from swirling up and form a coating film without defects on a substrate such as semiconductor by making at least part of section periphery shape of a supporting arm of the fixing tool into a curving shape in the substrate fixing tool of a spin type coating device. CONSTITUTION:A supporting arm 1 is formed to extend radially from a base rotary axis 3 and at least part of its section periphery shape is formed in a curving shape. A substrate 4 to be coated, for instance, a square base, is placed on base axis 3 when coating, and in case of a pin type fixing tool, the same is fixed by a pin provided on the supporting arm 1. At that time, a spacer is provided in the neighborhood of the pin and a space of approximately several mm - several cm is provided between the substrate 4, to be coated and the supporting arm 1. When the same is revolved in said state, laminar flow around the supporting arm 1 flows smoothly along a curve of the supporting arm 1. The laminar flow, therefore, flows without a turbulence such as vortex or the like generated in a device heretofore available, and swirling of dust in the device is eliminated to be able to form a coating film without defects on the surface of the substrate 4 to be coated. Similar effect can be achieved for a suction fixing tool, too.

Title: Motor-driven film winding device
Inventor: KITAJIMA TOMOYA
IPC: G03B17/00
Filed: 1985-10-17
Abstract: PURPOSE:To set the speed reduction ratio of a speed reducing gear so that maximum efficiency is obtained at average environmental temperature by providing a motor for film winding, a speed reducing gear system for decelerating the rotation of the motor, etc. CONSTITUTION:When a camera is used at average environmental temperature, a control member 7 is positioned at the 1st position by operating a changeover button. Then, the forward rotation of the motor is transmitted to a sun gear 1, whose clockwise rotation is transmitted to a winding gear 6a through a planetary gear 3 and the 1st intermediate gear 4 to rotate a film winding shaft 6, thereby winding a film. At this time, the total speed reduction ratio of the gears 1, 3, 4, and 6a is set small, so the energy of the motor is used efficiently to wind the film, which is wound at a high speed. When the environmental temperature is extremely low, on the other hand, the member 7 is positioned at the 2nd position. Further, when the film is rewound, a motor driving circuit is switched to reverse the motor, and then specific rewinding operation is carried out regardless of the position of the member 7.
