Patent JP-H06317666-A (JP)
Title: Fish detector
Inventor: YOSHINO TAKAMI
IPC: G01S15/96
Filed: 1993-05-07
Abstract: PURPOSE:To enable the detection of predicted information to be conducted by transducing an ultrasonic wave at a specified depression angle frontward of the bow, and displaying image information by a reflection signal on the image plane, at the same angle as the depression angle. CONSTITUTION:A frontward direction transducer 5 emits ultrasonic pulses into the water in the direction of a depression angle of 45 deg.. The reflected echo is sent to a receiving part 6, then A/D converted 7 and stored in a fish detecting buffer memory 8. Image data read from the memory 8 is sent to a coordinate transforming part 10 and sent to a display control part 14 after the transformation of a display address so as to be displayed along a display line. After converting image data into image data for display 16, the control part 14 receives the frontward direction display address and stores it in a display memory 15. The control part 14 further has the whole past image data scrolled by one picture element part on the image plane. The image from an obliquely frontward angle of 45 deg. to the vertically downward part (the vertically downward image becomes the past image) can be thus obtained with the advance of a ship, and the vertically downward image can approximately coincide with an A-scope image.

Title: Semiconductor device
Inventor: TANIGUCHI AKIHISA
IPC: H01L23/04
Filed: 1987-05-26
Abstract: PURPOSE:To prevent breaking of wires and peeling off of bonding pads, by covering a wire-bonded semiconductor chip and the wires with a cap and applying a coating material on the outer surface of the cap. CONSTITUTION:A semiconductor chip 2, wires 4 and bonding pads are covered with a cap 9 with a space interposed therebetween. The outer surface of the cap 9 is coated with a coating material 6 for protecting it when it is dipped in solder, and the cap 9 is thereby fixed to an insulating substrate 1. If the coating material 6 and the wire 4 are thermally expanded during temperature cycles tests or the like of the semiconductor device, their forces of expansion will not act mutually as they would according to prior arts. Therefore, it is possible to prevent breaking of the wires and peeling off of the bonding pads.

Title: Toner recovering device
Inventor: SASAKI KAZUHARU
IPC: G03G21/10
Filed: 1983-07-19
Abstract: PURPOSE:To separate paper powder or the like and crush and recover the lump of toner by sliding a brush, which is provided spirally around a revolving shaft of an auger in a toner carrying pipe, on a mesh member. CONSTITUTION:The toner carried into a pipe 1 by the rotation of the auger 2 includes foreign matters such as paper powder and the lumps of the toner; and when the toner comes onto a mesh member 3, a brush 4 which is slided on the inside face of the pipe 1 crushes the lump of the toner, and the lump of the toner is reproduced to a fine particle. The mesh member 3 of the pipe 1 is placed above the aperture of a toner bottle 7, and only the toner which can pass through the mesh 3 is dropped from the pipe 1 and is stored into the bottle 7. Foreign matters such as the paper powder cannot pass through the mesh 3 but passes on the mesh 3 by the auger 2 and are recovered into a tank in the outside of a developing machine as they are. The lump of toner which cannot be crushed on the mesh 3 and cannot pass through the mesh 3 is recovered into the tank 6 also.

Title: Centrifugal clutch
Inventor: BECKER GEORG
IPC: F16D43/18
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To precisely guide a centrifugal body so as to reduce abrasion by covering a clutch arm by means of a covering plate, which is held in the axial direction on the opposed positioned side to a supporting plate in the centrifugal body, in the radius direction at an axis directional guiding clearance. SOLUTION: As clutch arms 3a, 3b are covered in the radius direction at an axis directional guiding clearance, the clutch arms 3a, 3b are precisely guided in the axial direction by means of a guiding part 21 in a covering plate 5 when centrifugal bodies 2a, 2b are turned against returning force of a tension spring 8. Because a supporting plate 4 covers the clutch arm bodies 3a, 3b at a small axis directional clearance by means of its ring type circumference similarly, the clutch arm bodies 3a, 3b are precisely guided in the axial direction between the guiding part 21 in the covering plate body 5 and a guiding part 24 on the inside of the supporting plate 4. Therefore, rapid abrasion due to a load, which is applied to the bearing for the centrifugal bodies 2a, 2b because of an axis directional slide in an outward turning time, can be prevented.

Title: Brake booster having gasoline invasion-detecting switch
Inventor: MASUSHIRO NOBUO
IPC: B60T13/52
Filed: 1979-10-09
Abstract: PURPOSE: To prevent a brake booster from being broken by the invasion of gasoline by employing a member which swells when absorbing fuel as a contact of a switch provided on a vacuum brake booster body so that the switch is operated when the swelling quantity reaches a given value.  
     CONSTITUTION: When gasoline invades the vacuum chamber of a brake booster connected to an intake manifold 26, a rubber member 37 absorbs the gasoline and swells. When the swelling quantity of the member 37 reaches a given value, the member 37 moves rightwards against the energizing force of a spring 46. As a result, a metal plate 38 contacts with a contact member 39. Therefore, continuity is established between the first contact member 41, metal plate 38 and the second contact member 43, so that a lamp 50 is turned on.

Filed: 1988-05-27
Abstract: PURPOSE:To improve both the starting characteristics and the drivability of a four-wheel drive vehicle having a center differential by mounting a torque limiter in one of front and rear wheel driving systems to limit the differential operation of the center differential. CONSTITUTION:When an excessive torque is loaded on a torque limiter 8, the driving force of an engine 1 will not be transmitted to the driving system followed by the torque limiter 8, such as the output shaft 44c of a propeller shaft and a rear wheel axle 42.

Abstract: PURPOSE:To form a pattern in a good shape without decreasing a reflectance of a multilayer film reflecting mirror by making an X-ray exposure mask by a method wherein multilayer film reflecting mirror is formed on a substrate and then a reflection prevention film is formed according to a desired pattern on the multilayer film reflecting mirror. CONSTITUTION:A multilayer film reflecting mirror 2 is formed on a mask substrate 1 and then a reflection prevention film 4 is formed on the multilayer film reflecting mirror 2 according to a desired pattern 3, to make an X-ray exposure mask. For formation of the reflection prevention film 4 on the multilayer film reflecting mirror 2 according to a desired pattern, a resist coating process, a development process and a peeling process are required. However, the multilayer film reflecting mirror gets less damage in these processes compared with an etching process. What's more, a processing accuracy and a reliability can be remarkably increased since a circuit can be written by an EB lithographic equipment.
