Title: Concrete structure, resin plate for it, and its manufacture
Inventor: SAITO MASAHARU
IPC: B32B13/12
Filed: 1995-06-19
Abstract: PURPOSE: To establish a low-cost concrete structure and its manufacturing method excellent in the anti-seismic and load sustaining performance by consolidating concrete with a resin plate equipped with a surface unevenness. CONSTITUTION: A frame 2 is formed at the peripheral edge of a thermoplastic resin plate 1, and the inside of the frame 2 is furnished with a surface unevenness, and this is used as a concrete form while the flat surface of the plate 1 is positioned outside. Then concrete 7 is placed to generate a consolidated structure, and a concrete structure 8 is formed. The thickness of the plate 1 works as the effective section area so that it sustains a large flexural stress. Further intrusion of water/moisture, acids, etc., from the surrounding environment is shut off. Thus humidity, acid, alkali, etc., in the atmosphere are shut off to preclude deterioration of a concrete structure.

Title: Air-fuel ratio control for car engine
Inventor: ABE KUNIHIRO
IPC: F02D41/14
Filed: 1984-07-20
Abstract: PURPOSE:To prevent the erroneous operation in air-fuel ratio control by suspending the taking-in of the learned values due to the information supplied from an O2 sensor when the P-P value (difference between the max. and the min. values of the O2 sensor within a prescribed time) of the output voltage of the O2 sensor is below a prescribed value. CONSTITUTION:When an engine 1 is in operation, a microcomputer 15 corrects the fundamental injection amount Tp calculated on the basis of the inhaled air amount Q detected by an air-flow meter 17 and the number of revolution N detected by a crank-angle sensor 21 on the basis of the data such as those of an O2 sensor 16 and a water-temperature sensor 19 and controls an injector 4 according to the corrected fuel injection amount Tp'. In this case, the deterioration of the O2 sensor 16 is judged by judging if the P-P value of the O2 sensor 16 becomes below a prescribed value or not. For example, the max. and min. values of the output voltage of the O2 sensor 16 within a prescribed time are obtained, and when the difference between the both values becomes below a prescribed value, it is judged that the O2 sensor 16 is deteriorated, and then taking-in of the learned values according to the information supplied from the O2 sensor 16 is suspended.

IPC: F16H63/02
Filed: 1992-06-11
Abstract: PURPOSE:To prevent beforehand a bad operation such as an operation in which a changeover operation from a second state to a first state can not be carried out because of the leak of operation oil, by deciding the rear end position of the spring of a pressure governing valve by means of the second changeover portion of a changeover valve. CONSTITUTION:Even if operation oil leaks out of a first changeover portion 2PA and enters into a chamber 22a, this operation coil passes a cutout portion 22b from the chamber 22a inside and it discharged into a drain portion 35. As a result, the chamber 22a inside is kept at zero pressure at all times, and in a case in which a second changeover portion 29B is operated to the separation inside from the rear end of a spring 1Pb, from a state in which high second set pressure is set, the rear end of the spring 19b follows the second changeover portion 2PB without being separated, and returns to a first state surely. In addition, by providing the cutout portion 22b on the inner surface of a case 22, the position of the cutout portion 22b is fixed at all times without relation to the phase of the spool 29 of a changeover valve 24, and the operation oil in the chamber 22a is discharged into the drain portion 35 surely at all time.

Filed: 1989-06-14
Abstract: PURPOSE:To hold by suction and mount a plurality of components during one operation of an intermittent rotation of a main holder and to shorten a mounting tact per one component by performing a predetermined continuous operation at a plurality of nozzles of a sub-holder in respective stations. CONSTITUTION:After a component supply unit 1 positions a part cassette 10 mounted with a component tape 1 at a sucking position, four nozzles 4 held at a sub-holder 3 by a sub-holder rotating motor 8 are rotated to continuously hold components 12 by the nozzles 4 by suction in a station A. Then, predetermined operations are performed in stations B, C, D, E, F and G while the nozzles 4 are being continuously intermittently rotated by the motor 8. Thus, each time a main holder 2 is intermittently rotated, the four components 12 can be hold and mounted. Particularly, if the same components 12 are mounted on a board to be mounted with many components, tacts for mounting the four components 12 are largely shortened. Thus, the mounting tact can be shortened.

Title: Camera
Inventor: HIRANO MASAYASU
IPC: G03B7/093
Filed: 1991-05-27
Abstract: PURPOSE:To remove jiggling and to reduce jiggling change in the middle of releasing by calculating a shutter speed at which the detected jiggling amont of an object becomes a specified amount and correcting it in accordance with a focal distance in a panning mode. CONSTITUTION:When the panning mode is set by a panning/ordinary photographing mode changeover switch S3, a CPU 1 detects the moving amount of the object based on output data from a CCD line sensor 6. Then, the shutter speed at which the jiggling amount of the object becomes the specified amount is calculated. Shutter priority program exposure control is performed by using this shutter speed. Since the jiggling is detected based on the data just before releasing, there is possiblity that a photograph has large jiggling in the case that the jiggling just before the releasing is different from the jiggling in the middle of releasing. The longer the forcal distance of a lens is, the higher the possibility becomes, so that the shutter speed is corrected in accordance with the focal distance. For example, the shutter speed is made higher when the focal distance is long.
