Title: Intake duct
Inventor: FUJIWARA KAZUO
IPC: F02M35/12
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a low-cost intake duct which can reduce the intake noise when the engine is in low speed rotation and can suck the air in a sufficient quantity at the time of high speed rotation without use of any electronic control circuit or solenoid-operated opening/closing valve. SOLUTION: At least either of the negative pressure of an intake manifold and the motion of a throttle wire is utilized as a drive means to drive a valve 3 when engine is in high speed rotation so as to open the second line 2. At the time of low speed rotation, the valve 3 is closed and only the first pipe line 1 is opened, and the intake noise in the low temperature range is reduced. The valve 3 is opened at the time of high speed rotation so as to open also the second pipe line 2, and it is possible to secure a sufficient air intake quantity. The arrangement can be embodied at a low cost because negative pressure is used for driving the valve 3.

Title: Ion implantation device
Inventor: TODA HARUKI
IPC: H01L21/265
Filed: 1985-04-09
Abstract: PURPOSE:To surely implant ions into even an undulatory surface, by rotating a magnetic field generated near the surface, and by periodically changing the speed of the rotation, and moving an ion beam to scan the surface. CONSTITUTION:A magnetic field B is generated in a space shown by dotted lines in the drawing. The direction of the magnetic field B is rotated throughout an angle of 360 deg. on a plane parallel with the ion-implanted surface of an Si substrate 5, as shown by an arrow c. If the magnetic field B was not generated, an irradiated ion beam 2 would proceed straight as shown by a line 20. Since the magnetic field B is generated, the irradiated ion beam 2 is curved as shown by a line 21, so that the point of collision of the ion beam against the ion- implanted surface makes a locus 31. If the intensity of the magnetic field B is increased, the irradiated ion beam proceeds as shown by a line 22, so that a collision point locus 32 is made. If the magnetic field B is rotated at a slightly high speed and the intensity of the magnetic field is slowly changed, the locus of the ion beam collision point becomes concentric circles whose diameters are altered depending on the change in the intensity of the magnetic field.

Abstract: PURPOSE:To obtain a heat developing device which can apply uniformly the radiation heat from a photosensitive material on the photosensitive material by providing a reflecting plate having a reflection surface which reflects the radiation heat from the photosensitive material and applies the uniform incident energy to the photosensitive material in the transverse direction thereof. CONSTITUTION:An electrical heating element layer generates heat by the electric resistance thereof when electric current flows to the photosensitive material 11. The heat is generated in the entire part of the material 11 by such heat generation, by which the material 11 is heated and is heat-developed. The reflected heat from the material 11 is reflected by the reflection surface 38A of the reflecting plate 38 and is made again incident to the thermophotosensitive material 11. Since the reflection surface 38A is concave-shaped, the incident energy is uniformly applied in the transverse direction of the material 11 (the direction intersecting orthogonally with the pass line). The effective utilizing rate of the radiation heat is improved as well. A heat insulating material 39 is adhered to the plate 38 to minimize the quantity of the heat radiated from the rear of the plate 38, by which the effective utilizing ratio of the radiation heat is further improved.
