Title: Apparatus for supporting plural fishing rods
Inventor: YORIKAWA MASAO
IPC: A01K97/10
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for supporting plural fishing rods, enabling separate adjustment of the direction of the plural fishing rods S in vertical and horizontal directions and enabling quick attaching and detaching of the rods by using a water- container as a weight for the base part. SOLUTION: This supporting apparatus is composed of a water-container 1 and a rod-adjusting and supporting tool 2 detachably fixed to the upper edge of the container. The rod adjusting and supporting tool 2 is manufactured by erecting a forked support 4 on a base 3 supporting a freely rotatable shaft 5 extended between the top ends of the forks, placing a movable lever 6 with a fastening screw 7 screwed to the lever from above to allow the vertical tilting of the movable lever 6 from the horizontal position upward, and separately forming rod-receiving rods 8 at both sides of the movable lever 6 with a fastening screw inserted into the movable lever from under.  The rod-receiving rod 8 is provided with a through-cylinder 9 placed at the rear part to detachably hold fishing rods S at both sides of the movable lever 6 and with a top-opened holding cylinder 10 having a size slightly larger than the diameter of the rod. The fishing rods are separately adjustable in vertical direction above the horizontal direction and in horizontal direction and the fishing rods are quickly attachable and detachable by this structure.

Title: Device for switching connection of optical fiber connector
Inventor: TAMAKI YASUHIRO
IPC: G02B6/38
Filed: 1987-06-29
Abstract: PURPOSE:To shorten a switching time by bringing the flat surfaces of both 1st and 2nd connector ferrules in a connection state into tight contact with positioning surfaces and shifting a positioning pin in a guide hole. CONSTITUTION:The flat surfaces 11 of the respective connector ferrules 3A-3C are brought into tight contact with the positioning surface 23 of base boards 16A and 16B. Then a holding block 41 is moved along a guide shaft 48, respective projection pins 18 are inserted into the guide holes 12 of both connector ferrules 3A and 3B in the connection state from both sides, and both projection pins 18 are moved toward the rear end of the 1st connector ferrule 3A. Thus, the positioning pin 5 is shifted and arranged in the guide hole 12 of the 1st connector ferrule 3A so that it is extracted from the guide hole 12 of the 2nd connector ferrule 3B. In this case, the base board 16A maintains the positioning states of both connector ferrules 3A and 3B, so variation in the connection loss due to the extraction of the positioning pin 5 can be reduced.

Title: Ethernet repeater
Inventor: KURIYAMA MASARU
IPC: H04L12/28
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To eliminate a waste of transmission bandwidth even if a plurality of terminal devices which adopt different communication protocols are connected by selecting one of internal buses so that communication means form a common group, and providing a port group function. SOLUTION: When terminal devices are grouped into devices 46-1 -46-n , and 47-1 -47-n , bus switching parts 43-1 -43-2 connect them to an internal bus 42-1 and an repeating part 41-1 , and bus switching parts 43-3 -43-n connect them to an internal bus 42-2 and a repeating part 41-2 . Consequently, virtual transmission paths 51 and 52 are formed by the bus switching parts 43-1 and 43-2 , and 43-3 and 43-n . Both the virtual transmission lines are separated from each other, so the port group function which stops a communication between the groups can be obtained. When an Ethernet repeater is equipped with the port group function, there is no waste of transmission bandwidth even if terminals having a communication based upon different communication protocols are connected.

Title: Lighting system and projection type image display device
Inventor: SHIBATANI TAKESHI
IPC: G02F1/1335
Filed: 1992-06-22
Abstract: PURPOSE:To provide a projection type image display device which can provide illuminating light having good parallelism and a uniform illuminance distribution and can provide a uniform, bright screen of high picture quality while reducing the ununiformity of contrasts due to photoelasticity and restraining generation of color unevenness. CONSTITUTION:The form of a correcting lens 3 is designed following the Snell's law so that of rays of light reflected by a reflecting mirror 2 those which are not parallel to the optical axis 9 of a lighting system are refracted and made parallel to the optical axis 9. Illuminating light from the lighting system is therefore good at parallelism. Even when the relative positions of a light source 1 and the reflecting mirror 2 are adjusted so that the illuminating light is not extracted, the rays of light whose parallelism is made worse by deviating of the positions are made parallel by the correcting lens 3, so that the ununiformity of the illuminance of the illuminating light is improved without deteriorating the parallelism.

Title: Controlling device for parallel operation of motor
Inventor: KAMIYA HIDEO
IPC: H02P5/68
Filed: 1979-12-12
Abstract: PURPOSE: To keep the load ratio of each motor to be the same constantly by providing a detector for detecting armature current to each motor respectively, comparing the detected value in a comparison-amplifier and thus controlling the field current of each motor.  
     CONSTITUTION: The armature current of the motors M 1 , M 2  which are operated in parallel by a power source 1 is detected by the detectors 10 and 11, the detected value is compared by the comparison amplifier 12, and according to the difference in comparison the field current of the motors M 1 , M 2  is controlled. Therefore, when the fluctuation of load occurs and load sharing between the motors M 1 , M 2  changes during operation, the field current is adjusted so that the sharing is in accord, and thus stable operation can be performed constantly with the same ratio of load sharing. Moreover, by giving a nonsensitive band with some allowance and a property of hysteresis to the comparison-amplifier 12, unnecessary transfer of load sharing, even the slightest fluctuation of load, can be prevented.
