Abstract: PURPOSE: To reduce the number of evacuation pumps and improve the operating efficiency, reliability, and safety of the evacuation pump by providing a roughing vacuum pump attachably and detachable connected to the exhaust hole of a vacuum tank to exhaust the air in the vacuum tank, and a pressure connecting means. CONSTITUTION: A roughing vacuum pump 5 is made attachable to and detachable from the exhaust hole 2 of a vacuum tank 1, and the pump 5 is pressed to the hole 2 side by a pressing (pressure connecting means) 4 at connection. When the vacuum roughing of the tank 1 is started, the vacuum roughing device is first moved to under a gate valve 3, the pump 5 is pushed up by the mechanism 4, and a vacuum seal part flange 7 and the vacuum seal surface of the valve 3 are mutually connected through a metal gasket or O-ring.

Title: Dual mode horn antenna
Inventor: NATSUHARA KEIICHI
IPC: H01Q13/24
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide excellent directivity in the frequency over wide band by taper-connecting a conical waveguide and a linear waveguide and filling dielectric inside a horn. SOLUTION: The connection part 10 of the conical waveguide 2 and the linear waveguide 3 is smoothly connected by a tapered part 6. Thus, a TM11 mode is generated only from a rectangular connection part (non-continuous part) 20. That is, since a high order mode is generated only in the case that the non-continuous part 20 is present, the high order mode is not generated from the connection part 10 smoothly connected by the tapered part 6. Thus, the dielectric 7 is filled inside the horn 4 and a beam width is varied by appropriately selecting the dielectric constant of the dielectric 7 as a parameter. The beam width is decided by the size of a horn opening part 5. Thus, by appropriately selecting the dielectric constant of the dielectric 7, the beam width is optimized as well.

Title: Spectroscopic apparatus
Inventor: TANIMOTO TAKAO
IPC: G01J3/06
Filed: 1988-08-29
Abstract: PURPOSE:To correct a wavelength with high accuracy over a wide wavelength region by utilizing the moving quantity of the detection position of the reference light detected by a photodiode array to measure the angle of revolution of a dispersion type spectroscopic element over an entire measuring wavelength. CONSTITUTION:The reference light (b) emitted from a diffusion type spectroscopic element 3 is applied to a photodiode array 10 through a slit 9. Since the reference light (b) has only the wavelength component of a reference wavelength, when the spectroscopic element 3 is revolved, the output direction of the max. luminous intensity corresponding to said reference wavelength is also moved and, therefore, the max. luminous flux position of the reference beam (b) applied to the array 10 through the slit 9 is moved. Since this moving quantity corresponds to the angle of revolution of the spectroscopic element 3, the angle of revolution of the spectroscopic element 3 is calculated from the moving quantity. Since the relation between the angle of revolution of the spectroscopic element 3 and the wavelength of the light incident to the slit 9 is uniquely determined on the basis of the relative positional relation between a collimator mirror 2, the spectroscopic element 3, a camera mirror 4 and the slit 9, a wavelength to be measured can be accurately calculated when an angle of revolution is accurately calculated.

Title: Oil hydraulic circuit and control valve used for said circuit
Inventor: OOZEKI MASAHIKO
IPC: F15B11/16
Filed: 1981-12-28
Abstract: PURPOSE:To simplify the circuit constitution by transferring a pilot operation valve provided on a parallel passage to a free flow passage position or a throttle passage position by means of the difference of operating pressures of a plurality of actuators. CONSTITUTION:Neutral paths 15-18 of control valves 10-13 are connected in tandem and a pilot operation valve 33 is provided on a parallel passage 21. When a valve 13 is operated alone, a motor 22 side is at a low pressure and the valve 33 is placed at a free flow passage position 36 which is a normal state. When the valve 12 is operated to place the valve 13 at the right position, a cylinder 23 is under a higher load pressure than that of a motor 22, thus the valve 33 is not moved. Next, when the valve 13 is placed at the left position, a passage 30 is made at a tank pressure and the pressure in a pilot chamber 35 is made lower than that of a pilot chamber 34, and the valve 33 is transferred to a throttle passage position 37, thus squeezing the feed of the pressure oil into the cylinder and preventing the pressure oil from being fed restoratively during the descending stroke of the cylinder.

Abstract: PURPOSE:To attain the highly accurate aligned winding of a double azimuth head by locking a wire on a locking body to prevent the wire from being loosened at the insertion process of the wire, and at the time of winding the wire, adjusting the upper and lower positions of the locking body. CONSTITUTION:In the case of winding the wire X around the inside 95 of the head 90 held between holding boards 2, 2', the terminal end of the wire X is locked on a hook chip Y, and after inserting the wire X into the gap 92, the wire X is penetrated into a hole 91 and pressed on the holding board 2 by a lock pin 1 to lock the wire X. Thereby, tensile force is applied to the wire X to form a tension part x and a wound part y wound to the inside 95 by a half of revolution is not loosened. While pulling the chip part of the wire X, the lock pin 1 is moved upward and approached to the head 90 to determine the forming position of the wound part y. When the lock pin 1 is pulled out from the state while tensing the tip part of the wire X, the wire X is completely wound up around the inside 95 to complete the winding of one round. The operation is repeated to attain looseless winding.

Title: Photosensitive solid-state oscillation element
Inventor: YAMATO TOSHIYA
IPC: H01L31/10
Filed: 1982-12-08
Abstract: PURPOSE:To increase the substantial photo receiving area and reduce the chip area by a method wherein the photo receiving surface of a photosensitive solid- state oscillation element which operates by oscillation by light irradiation is formed into wave form or uneven form. CONSTITUTION:The photo receiving area is increased by changing the surfaces of an N type grown layer 2 and a P type diffused layer 3, i.e., the photo receiving surface of the photosensitive solid-state oscillation element into a wave form. The form of this photo receiving surface can be in irregular unevenness. From the point that the photo receiving area increases, the light reaching the photo receiving surface from a light source is well absorbed to the surface, photosensitivity more improves than in the case that the photo receiving surface is a plane, and the oscillation is disclosed with a small amount of light. On the other hand, if the amount of light is the same, the element oscillates at a high frequency.
