Title: Distributor for internal combustion engine
Inventor: TERAKADO TAKAO
IPC: F02P7/04
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To improve waterproof performance of a distributor by forming a thickness of a positioning fixing part cross section of packing thinner than a thickness of a circular seal part cross section at compressing time by pressing of a cap. SOLUTION: Packing 3 is fitted to a projection 2-3 of a cap 2 and a packing positioning fixing part 3-2, and is held by the cap 2. A packing seal part 3-1 and the positioning fixing part 3-2 are in the same thickness, and the cap 2 receives reaction from the packing seal part 3-1 and the positioning fixing part 3-2 at compressing time of the packing 3. However, since the packing positioning fixing part 3-2 is thinner than the packing seal part 3-1, it is not compressed even at pressing time of the cap 2, and since a warp of the cap 2 can be reduced only to reaction from the packing seal part 3-1 since reaction is not caused, a contact part is limited only to the packing seal part 3-1, and line contact can be made.

Title: Gas laser resonator
Inventor: KARASAKI HIDEHIKO
IPC: H01S3/041
Filed: 1993-07-20
Abstract: PURPOSE:To stabilize laser power by providing a structure which allows a gas laser resonator to have small shape deformation due to external air pressure. CONSTITUTION:A gas laser resonator is formed by permitting a pair of main flanges 5 connected by a main pipe 14 to hold the edges of a discharge tube 8. The inside of the main pipe 14 is divided into an inlet pipe 9, which introduces laser gas, and an outlet pipe 11, which exhausts laser gas. Since the arrangement of the laser gas circulation path including a heat exchanger 10 is permitted to be symmetrical, shape deformation is reduced by offsetting the stress of external air pressure applied on the laser resonator, and the laser power is stabilized. The introduction temperature and the exhaustion temperature of laser gas are detected by a temperature sensor 15, and the flow of the cooling medium of the heat exchanger 10 is controlled so as to permit the temperature difference within 3 deg.C or less. Thus, more laser power improvement and stabilization is attained.

Title: Eddy current type metal detector
Inventor: ANDO SEIGO
IPC: G01N27/72
Filed: 1985-08-14
Abstract: PURPOSE:To stabilize an oscillation output voltage and to suppress a hysteresis phenomenon and to improve the detection precision by detecting variation in oscillation output voltage due to variation in the temperature of a detection coil and a connection cable as variation in resistance and performing feedback control. CONSTITUTION:The output terminal of the parallel resonance circuit 14 composed of a detection coil 12 for detecting the proximity of a body 11 to be measured and a capacitor 13 is connected to the plus-side input terminal of an amplifier 16 through the connection cable 15. Then when the ambient temperature (t) varies, the composite resistance (r) of the coil 12 and cable 15 varies, and consequently the amplitude value of an output signal eO varies. A low-pass filter 21 removes its AC component eO and then a DC voltage EO proportional to the resistance (r) is developed at the output terminal of the filter 21. This DC voltage EO is converted by a DC/AC converter 23 into an AC control signal eC of original frequency fO, which is applied to an adder 19 through a switch 24 to control a positive feedback rate beta and thus adjust the amplitude value of the output signal eO of an amplifier 16, thereby compensating amplitude variation due to the temperature variation of the coil 12 and cable 15 automatically.

Title: Reel control method for magnetic tape device
Inventor: TAKEUCHI RYUICHI
IPC: G11B15/58
Filed: 1984-08-28
Abstract: PURPOSE:To prevent tape from being dislocated from its specified position or damaged by permitting two-way switching of rotation speed of take-up reel and setting the rotation speed to be very low at the time of unloading. CONSTITUTION:A voltage comparator Qb having resistance Rc and Rd is added to a rotation speed control circut of the take-up reel 5 for motor rotation speed setting at the time of unloading. When an instruction signal for unloading is inputted to a flip-flop Qe, therefore, motor inducing voltage V0 and rotation number setting reference voltage V2 set by the resistance Rc and Rd are compared in the voltage comparator Qb, and the number of rotation of the motor 5m is controlled so that V0 is equal to V2. Since V2 is set to rotate the coiling reel 5 at low speed at that time, the take-up reel 5 rotates slowly. This permits to reduce tape tension at the moment when tape in vacuum column is wound up.

Abstract: PROBLEM TO BE SOLVED: To express an area which was unexpressable by a sheet of a reference surface before by converting multi-view-point images to light beam space data corresponding to the plural reference surfaces. SOLUTION: The number of the reference surfaces of a light beam space and the arrangement are decided. Then, the view point position and line-of-sight direction of an observer are detected by a view point position/line-of-sight direction detector 12. Thereafter, the size of an image to be generated and a viewing angle are decided. When the image size and the viewing angle are decided, multi-view-point image data and a parameter at the time of photographing the image stored in a storage device 14 are extracted. Then, the direction of a light beam passed through the respective picture elements of a CCD and the lens center of a camera is obtained from the extracted parameter and which one of the four reference surfaces recording is to be performed is decided by the value.  The color of the light beam, the number of the original multi-view-point image corresponding to the light beam and the number of the picture element are recorded in a space corresponding to the decided reference surface. Thereafter, a part where the value is undecided is interpolated on the space. Then, from the view point position and line-of-sight direction of the observer, the image corresponding to them is generated.
