Title: Bucky device
Inventor: HORIKAWA KAZUO
IPC: A61B6/06
Filed: 1988-03-19
Abstract: PURPOSE:To prevent transmission of oscillation to ambient members by offsetting the shift of the centroid of the Bucky device by the movement of a grid by the transfer of a balancer. CONSTITUTION:The grid 81 moves back and force repeatedly in a horizontal direction when an operator elongates a spring 83 connected to the grid 81 by largely pulling a gripping means 84 of the Bucky device 80 and releases the gripping means. The greater part of the radiations scattered by a subject 12 can be removed by this device 80 and the generation of moire fringes in the visible image to be obtd. in the final is prevented. The balancer 82 which is connected at one end to a spring 5 and is connected at both ends to the grid 81 by connecting members 86A, 86B is further provided to the device 80. The centroid of the balancer 82 moves to the right (left) when the centroid of the grid 81 shifts to the left (right). The shift of the centroid as the whole of the device 80 is thus prevented.

Title: Vibration type compressor
Inventor: FUJIYAMA CHIKAHIDE
IPC: F25B9/14
Filed: 1994-04-05
Abstract: PURPOSE:To improve reliability of a compressor by effectively insulating a coil without reducing a processing accuracy and without causing contamination. CONSTITUTION:A coil arranging recess 31 is provided at a bobbin integral with a piston. A coil 25 is formed in the recess 31. A nonconductive resin sheet 47 is held on a surface of the recess 31 by a lead 33 of the coil 25 thereby to provide an insulator 45. A resin using amount is reduced as compared with that when an entire bobbin 29 is formed of the resin, and a contamination does not become a problem. The bobbin itself is made of metal and can hold a high processing accuracy. When the insulator 45 is provided by the same resin using amount as that in the case of prior art in which the lead 33 is covered with resin, a thickness of a resin layer becomes larger than that of the prior art.

Filed: 1988-03-23
Abstract: PURPOSE:To form a connecting hole through micro-processing while forming a tapered section on the side surface of the connecting hole by forming the connecting hole by combining wet etching and etching through an RIE method. CONSTITUTION:A resist pattern 3 is shaped onto an inter-layer insulating film 2 and recessed sections 4 are formed to the inter-layer insulating film 2 through wet etching as a first process. Opening sections 6 continuing to the recessed sections 4 are shaped through etching by a reactive ion etching(RIE) method while using the resist pattern 3 as a mask and connecting holes 8 are formed in a second process. Accordingly, since the upper sections of the connecting holes 8 are shaped through wet etching and the lower sections of the connecting holes 8 are formed through etching by the RIE method, the connecting holes 8 can be shaped through micro-processing while tapering working can be executed to the side surface sections of the upper sections of the connecting holes 8.

Title: Decompression device for engine
Inventor: MATSUMOTO KAZUYOSHI
IPC: F01L13/08
Filed: 1989-03-17
Abstract: PURPOSE:To prevent the occurrence of vibration and noise, when engine speed has decreased below a prescribed value, by regulating the return of a valve while turning a rocker arm at the time of the compression stroke so as to open the valve, and by releasing the return of the valve at the time of the explosion stroke so as to close the valve. CONSTITUTION:When an engine is operated, a stem end 9a is pushed down by the rocking motion of a rocker arm 8 as a camshaft 5 is turned, and a valve 9 is opened or closed in a prescribed timing. As the camshaft 5 is turned, the open ends of first and second communicating passages 18a, 18b move, and first and second oil passages 22a, 22b are periodically communication with a supply passage 19 via these communication passages 18a, 18b. At that time, if the engine speed is decreased below a prescribed number of revolutions to open a check valve 29, the rod 26a of an actuator 25 is protruded against a spring 28 by the discharged oil of an engine-driven oil pump 21, so that the return of the rocker arm 8 is regulated and the inside of the combustion chamber 3 is brought to a half-compressed condition.

Title: Locking device
Inventor: SAIKAI KENICHI
IPC: F15B11/00
Filed: 1993-03-03
Abstract: PURPOSE:To prevent a valve body from closing again accompanied with the rearward movement of a spool which may be caused by pressure increase in a chamber in front of the spool by moving the spool foreward, and interrupting introduction of pressure in a hydraulic cylinder into a chamber behind the valve body. CONSTITUTION:A valve body 11 retreats by pressure from a pump 1, for opening. The valve body 11 is opened by introducing pressure from a hydraulic cylinder 5 into a chamber 17 behind the valve body, and locked. When oil is discharged, pilot pressure is introduced into a chamber 27 behind a spool 13. The spool 13 is moved foreward against energizing force of a spring 25. Thus, introduction of the pressure of the hydraulic cylinder 5 is interrupted. By this interruption, oil flow from the hydraulic cylinder 5 is also interrupted. Pressure loss caused by the oil flow is suppressed. It is, accordingly, possible to prevent the spool 13 from moving rearward again which may be caused by pressure increase in a chamber 39 in front of the spool.

Abstract: PURPOSE:To form an electrically conductive pattern excellent in adhesive property by combining annealing due to light and a light CVD method wherein the light passing through a mask having a desired pattern as light-transmitting region is made excitation light in case of forming the electrically conductive film pattern on a substrate in the atmosphere contg. reaction gas. CONSTITUTION:An Si substrate 1 having an SiO2 film is put at the bottom part of a reaction chamber 2 and heated at 250 deg.C with a heater 3. Gaseous SiH4 5, gaseous PH3 6 and gaseous He are supplied into the reaction chamber 2. Then, the oscillating light 9 of Ar<+> laser is made incident so that it is focused on the substrate via a mirror 10, a lens 11 and a mask 12. Since the mask 12 is set at the position of 1mm. over the substrate 1 and the power density of oscillating light 9 at the mask position is lower in comparison with the power density on the substrate, polycrystalline Si is not built up on the mask 12 and a distribution pattern due to the n type polycrystalline Si in accordance with the pattern is formed on the Si substrate. Next, the adhesive property of the distribution pattern of polycrystalline Si is improved with the annealing of oscillating light 14 of CO2 laser by means of the mirror 10.
