IPC: H01L21/304
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To prevent generation of voids without applying special restrictions during a passing time from the end of a bonding process to the start of a bonding heat treatment process, by applying hydrophobic treatment using hydrofluoric acid to a base wafer, and applying hydrophilic treatment to an active wafer. SOLUTION: A mirror-finished silicon wafer is used as a base wafer, to which hydrophobic treatment is applied. A natural oxide film is eliminated and the wafer is cleaned. The single surface or both surfaces of an active wafer 2 are mirror-polished, and insulating films 2a having a specified thickness are formed by heat treatment. Hydrophilic treatment is applied to the active wafer 2, impurities are eliminated, and OH groups are imparted. By using a bonding tool, the active wafer 2 is bonded to the base wafer 1 with pressure, and then bonding heat treatment is performed. Therefore, very excellent bonding is realized, voids are not generated for a long time, and a clad wafer of high reliability can be obtained.

IPC: B66D3/00
Filed: 1989-11-08
Abstract: PURPOSE:To improve safety and reduce labor by providing a means for forming an engaging cam face on an engaging cam body holding a travelling rope and for rotating-energizing the engaging cam body upward, and an engagement releasing means for rotating-operating the engaging cam body downward. CONSTITUTION:When a travelling rope 3 is wound around a pulley 4 supported above, a load 25 is hung on a hook-part 5, and the travelling rope 3 extending through the pulley 4 back downwardly is pulled downward, the load 25 is lifted up. In this case, because an engaging cam body 10 is rotated-energized upward, the travelling rope 3 travels smoothly without being locked. On the other hand, when the travelling rope 3 is released, etc., the load 25 begins to lower, and the operating side of the travelling rope 3 is moved upward between a guide roller 7 and the engaging cam body 10, so that the engaging cam body 10 is turned upward to hold the travelling rope 3 between the guide roller 7 and the engaging cam body face of the engaging cam body 10 to prevent the fall of the load 25. Further, when a release wire 15 is lowered downward to rotate the engaging cam body 10 downward, the travelling rope 3 can freely travel.

Title: Fuel injection device
Inventor: SAITO HIDETOSHI
IPC: F02M55/02
Filed: 1986-12-08
Abstract: PURPOSE:To aim at preventing a compression-ignition type internal combustion engine from offering nonconformity such as secondary injection or the like by providing a check-valve having a flat valve body in a high pressure fuel passage. CONSTITUTION:When a plunger 5 rises from the bottom dead center to close a fuel suction and discharge hole 7, high pressure fuel in a high pressure chamber 6 is led through a high pressure passage 25 and injected into a cylinder from a nozzle 19. In this phase, a check valve is opened to prevent the stream of fuel from being hindered. When the plunger 5 further rises, a fuel control groove 10 communicates with the fuel suction and discharge hole 7 so that fuel in the high pressure chamber 6 is relieved into a fuel sump 8, and therefore, the injection of fuel from the nozzle 19 is inhibited. At this time, the check valve 33 is closed so as to prevent fuel from counterflowing, so that the residual pressure in the high pressure fuel passage 25 is held at a high value, and further since the valve element 33 of the check valve 33 is flat, the dead volume of the high pressure fuel passage 25 is reduced to aim at improving the injection characteristic during low speed running.

Title: Vibration reduction type linear compressor
Inventor: PAAKU JIYUN SHIKU
IPC: F04B17/04
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To reduce the vibration of a sealed container during the operation of a compressor by making the vibrating direction of a mounting spring and the exciting direction of a compression unit cross at right angles. SOLUTION: The base ends of mounting springs 22, 22 are hooked on each stepped part 21a, 21a within a sealed container 21 bent into a hollow cylinder and horizontally arranged, and a compression unit 23 housed within the sealed container 21 is hooked on the tips of the mounting springs 22, 22. As the smaller the rigidity of the mounting springs 22 is, the smaller the amplitude of the compression unit 23 is. Consequently, since the rigidity of the mounting springs 22 is about 1/3, compared with the rigidity in vertical set when the compression unit 23 is set in horizontal form, the force added to the sealed container 21 of the compressor is reduced to about 1/3. Thus, the amplitude of the sealed container 21 during the operation of the compressor is reduced.

Abstract: PURPOSE:To prevent a line part of a transfer image from becoming a state that the inside is omitted, in its line part, and to obtain a satisfactory line image, by electrifying a toner image to the same polarity as an electrification polarity of a magnetic toner by a post-electrifier. CONSTITUTION:Images of two colors are formed by developing successively or simultaneously two kinds of electrostatic latent images which have been formed, based on different image information on an electrostatic latent image holding body 1, by a nonmagnetic toner and a magnetic toner which have been electrified to the opposite polarity to each other, and these toner images formed by a development are electrified uniformly by a post-electrifier 7, and thereafter, in the case of forming an image on transfer paper 9 by transferring this toner image to the transfer paper 9, the toner image is electrified to the same polarity as the electrification polarity of the magnetic toner by the post-electrifier 7. Accordingly, in the line center part of the toner image, no transfer failure is generated. In such a way, such a problem as a line-like image becomes an image whose inside is omitted can be obviated.
