Title: Intake device for internal combustion engine
Inventor: ITO ATSUSHI
IPC: F02B27/02
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To improve output in intermediate and low speed region, by providing a first intake pipe whose one end is connected to an air cleaner and the other end can be connected to a surge tank and a second intake pipe whose one end is connected to an air cleaner and the other end can be connected to a surge tank in parallel, and changing over and using the first and second intake pipes. SOLUTION: In operation of an internal combustion engine, a signal of rotational frequency of the internal combustion engine is input into ECU 20, and whether the rotational frequency is higher or lower than a specific rotational frequency is judged. When the judgment is NO, air flowing through an intake pipe 4 is shielded by operating a negative pressure control valve 19 and closing an intake path switching valve 6 with a diaphragm 7, and air communication through an intake pipe 5 is ensured. When the judgment is YES, air communication through an intake pipe 4 is ensured by opening the negative pressure control valve 19 and the intake path switching valve 6.  Thus, in region where rotational frequency is lower than a specific rotational frequency, filling efficiency of intake which is filled in cylinders 15-18 is increased to provide high output, and in region where rotational frequency is higher than a specific rotational frequency, filling efficiency of intake which is filled in cylinders 15-18 is increased in its intermediate speed region to provide high output.

IPC: G11B5/55
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a method to reduce the error caused by impact at a comparatively lower cost. SOLUTION: The error is compensated (108, 111) in accordance with correction data (FF(n-1)) stored in a memory by detecting (100, 102) the impact and responding this detection. This method is applicable to an optical disk player, e.g. an information reading device such as a CD or DVD. The updating of the correction data stored in the memory based on the error which is measured on the detection (104) of the decreasing error by the above-mentioned method, is profitable, and by such a learning programing, the compensation becomes more and more effective at each sequential impact in a certain series of impacts.

Title: Rotary reciprocating compressor
Inventor: HIROSHIMA MINORU
IPC: F04B37/00
Filed: 1977-09-14
Abstract: PURPOSE: To obtain a rotary reciprocating compressor without necessitating the machanism to convert the rotary movement into the reciprocating movement by rotating one columnar member within a cylinder and effecting the reciprocating movement by the sloped surface of the columnar member which rotates the remaining columnar member.  
     CONSTITUTION: A rotary columnar member 4 within a cylinder 3 provided with a suction opening and a vomitting opening 2 is permitted only to rotate. And, a reciprocating columnar member 5 is permitted only to reciprocate by means of the key or the like provided in the axial direction. As the rotary columnar member 4 rotated, the position of a contact (S) between the rotary columnar member 4 and the reciprocating member 5 moves on the outer peripheral portion of the sloped surface 5 of the reciprocating columnar member 5 towards a point nearest the bottom surface. At the same time, the reciprocating columnar member 5 moves to the rotary member 4 side and thus the space between the columnar members 4, 5 and the inner wall of the cylinder 3 decreases so as to effect the compression function. And, if the rotary columnar member 4 rotaes, the space increases so as to start the suction stroke

Title: Tank protected by grease from damage due to freezing of soil
Inventor: ABE TAKESHI
IPC: F17C13/10
Filed: 1978-09-07
Abstract: PURPOSE:To protect an underground low-temperature tank from damage due to the freezing of soil around the tank, by providing grease between the soil and the outside surface of the tank. CONSTITUTION:When the soil 01 in contact with bags 8 are frozen, the soil rises. Since the bags 8 are packed with the grease 9, only a little bonding force acts between the outer body 1 of the tank and the bags 8 and between the frozen soil and the bags. Therefore, the outer body 1 and the soil freely slide relatively to each other on the bags 8 and no lifting force is applied from the frozen soil to the outer body 1. The outer body 1 remains in a fixed position by its own weight and the weight of stored liquid 10 or the like in the tank. Thus, the bottom of the tank is protected from damage due to the frozen soil around the tank. It is very easy and economical to pack the bags 8 with the grease 9 put on the market and interpose the bags between the soil and the outer body 1 of the tank when burying the outer body.

Filed: 1989-04-28
Abstract: PURPOSE:To make the light transmittivity and the light reflection factor constant irrespective of the plane of polarization, to improve the signal-to-noise ratio and to contrive the miniaturization and the simplification of an assembly adjustment by using the non-polarization beam split surface as a separating means for a light beam. CONSTITUTION:A light beam 61 from a semiconductor laser element 58 is brought to linear polarization in the minor axis direction of the elliptical surface, transmits through the non-polarization beam split surface 53 and irradiates an optical disk 70. Subsequently, the reflected light beam 61 from the disk 70 is reflected by the surface 53 and made incident on a convex lens 75 fixed to a beam splitter 88. Next, the light beam is separated into two light beams by the splitter 88, and detected by photodetectors 81, 82, respectively. Since the surface 53 is non-polarization, when a ratio of light transmittivity or a reflection factor to S and P polarization components is within a prescribed range, even if the element 58 is rotated from a prescribed position, reproduction, recording and erasion can be executed stably. Accordingly, the signal-to-noise ratio is improved, the optical head is miniaturized and the assembly adjustment is simplified.
