Title: Filter device for reducing noxious discharged article from crankcase in internal combustion engine
Inventor: SWEETEN THEODORE P
IPC: F01M13/00
Filed: 1991-07-03
Abstract: PURPOSE: To separate and remove a liquid portion from a gaseous portion in the crankcase emission emitted from a crankcase without using a conventional air ventilation hole or a storage vessel. CONSTITUTION: A filter apparatus 20 comprises a housing 25, 29, and filtering material 21 arranged in the housing. The housing has an inlet 32 and an outlet 27. Crankcase emission directed from the inlet 32 is filtered by the filtering material 21. A gaseous portion is delivered from the outlet 27 to a combustion chamber of an engine through a PCV line or an induction manifold. A liquid portion separated by the filtering material 21 is returned from the inlet 32 to the crankcase.

Title: Manufacture of thin film resonator
Inventor: OHASHI HIROSHI
IPC: H03H9/17
Filed: 1988-06-30
Abstract: PURPOSE:To reduce the occurrence of deflection or crack and to form a thin film resonator with high mechanical strength and less deterioration in its characteristic at resonance by dispersing a distortion stress of a thin film resonance part. CONSTITUTION:A piezoelectric member made of ZnO or the like with electrode materials clipped thereupon and a thin film resonance part whose upper and lower faces are fitted by SiO2 are separated from a silicon substrate 31 via a space layer 40. Moreover, the thickness of an etching member embedded in a silicon substrate etching part is selected to the etching depth subtracted by nearly a half the thickness of the thin film resonance part to mate the center face of the thin film resonance part nearly with the surface and its prolonged line of the silicon substrate 31. Since the thickness of the electrode thin film is usually sufficiently thinner than that of other thin films, the entire thin film resonance part is nearly symmetrical in the broadwise direction and the distortion stress on the film border is cancelled in the entire multi-layer film thereby reducing the occurrence of deflection or crack considerably.

Title: Phase element
Inventor: ITO KIYOSHI
IPC: G11B11/10
Filed: 1987-06-29
Abstract: PURPOSE:To compact a phase element by selecting the refractive indexes and film thicknesses of 1st and 2nd thin films so that the phase difference between the S-polarized light and P- polarized light of composite parallel luminous flux from the border surface between a prism and the 1st thin film to the prism side is a specific angle. CONSTITUTION:A thin film 14 which has a refractive index n1 and film thickness d1 is vapor- deposited on the oblique surface 12 of the right-angled prism 10 with a refractive index n0 and a thin film 16 with a refractive index n2 and film thickness 16 is further vapor-deposited on this thin film 14. Then the parallel light flux is incident on a prism surface with a refractive index n0 at right angles and reflected and refracted by the border surface of the 1st thin film 14 adhered on the prism surface of the prism 10, and the light is reflected and refracted by the border surface between the 1st thin film 14 and the 2nd thin film 16 laminated on the 1st thin film 14 and reflected totally by the border surface between the 2nd tin film 16 and the outside; and the refractive indexes n0-n2 of the prism 10, 1st thin film 14, and 2nd thin film 16, and the film thicknesses d1 and d2 of those thin films 14 and 16 are so selected that the phase difference between the S-polarized light and P-polarized light of the composite parallel luminous flux traveling from the border surface between the prism 10 and 1st thin film 14 to the prism is the specific angle. Consequently, a compensating plate as another body is not necessary and the optical system can be made compact.

IPC: H01S5/00
Filed: 1995-06-29
Abstract: PURPOSE: To realize a semiconductor device of high reliability by a method wherein an active layer of distorted multi-quantum well structure which has an enough allowance for critical conditions related to the occurrence of dislocation.

Title: Section taking-out method in gathering machine and device thereof
Inventor: FUJIMOTO SHUJIRO
IPC: B65H3/48
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent section from staining due to the rubbing of the sections with each other at the time of taking out the sections by sending air for reducing sliding friction between the sections to be taken out and a fold section placement surface and between the section to be taken out and a section just above it. SOLUTION: Right and left nozzle 31, which is cylindrical and is at the lower end of a compressed air passage 39, involves a recessed blown-off air guiding part 41 which is opened inward in the lateral direction. The compressed air which is blown-off from the nozzle 31, being deflected by 75 degrees from the perpendicular enters the space between the lowest section F and a section F just above it and the space between the lowest section and the placement plate of a section placement part 2 and travels inward in the lateral direction so as to be a sector spread in the longitudinal direction. As a result, sliding friction force by the gravity of the sections F which are loaded is reduced largely to facilitate taking out the lowest section.  It is thus possible to prevent two sections from coming out at a time and the sections from staining due to their rubbing with each other even if sections F are loaded more than in the past.

Filed: 1986-07-11
Abstract: PURPOSE:To reduce the influence of flow force by constituting a variable throttle part by openings provided around a spool part, the inner wall of a small diameter hole, and a ring-shaped groove. CONSTITUTION:In a valve body 41, small diameter holes 41b and 41c of the same diameter are coaxially provided on both the upper and lower sides of a large diameter hole 41a. At the end of the large diameter hole on the near side to a valve seat 41d and at the intermediate part of the lower small diameter hole 41b, ring-shaped grooves 41e, 41f are formed, and at the intermediate part of a spool part 42c, openings 42c1 communicating with the first oil chamber R11 are formed.

Thus, since the flow passage formed between the taper surface 42a1 of the poppet valve part 42a and its valve seat 41d functions as a mere passage and fluid is throttled by the variable throttle part A, the influence of flow force can be reduced.

Abstract: PURPOSE:To prevent the occurrence of disturbance of write and read operations, by executing the restart against the period before the capstan is stopped, at the position where a tape is vibrated little. CONSTITUTION:A pulse which is generated in accordance with a tape speed outputted by a capstan tachometer 5 is counted by a counter 6 and is provided to a program controlling circuit 7.
