Title: Inspecting method of composite lens
Inventor: MORIKAWA EIJI
IPC: G01M11/00
Filed: 1983-12-20
Abstract: PURPOSE:To inspect a composite lens in an operation state by putting the composite lens in prescribed oscillation, and detecting a play occurring to a lens or spacer, etc., visually and an ultrasonic wave component generated by it quantitatively. CONSTITUTION:The composite lens 10 to be inspected is fixed on an oscillation generating device 11. An audible frequency signal of 200Hz-1kHz from an oscillator 12 is amplified by an amplifier 13 then applied to the oscillation generating device 11 to oscillate the body 10 to be inspected in at least one direction. The inspection by this method is attained by observing the motion of the lens spacer of the composite lens 10 visually through an optical stereo microscope 18 or dstecting the ultrasonic wave component generated in case of a play by an ultrasonic sensor 14. For example, the frequency at which a maximum play is recognized is searched for by the oscillator 12 through the observation of the optical stereomicroscope on the basis of the output of the ultrasonic sensor 14.

Title: Continuously variable transmission
Inventor: HAYASHI KIYOTAKA
IPC: F16H61/00
Filed: 1987-09-25
Abstract: PURPOSE:To accomplish power transmission of a belt reliably from the low- speed rotation of an engine without damaging power transmission and to reduce transmission loss by forming a small hole on a differential pressure adjusting piston for communicating a low pressure portion with a high pressure portion, which are provided on both sides of the piston. CONSTITUTION:As a small hole 43b is disposed on a differential pressure adjusting piston for communicating a low-pressure portion and a high pressure portion which are provided on both sides of the piston, when the flow of pressure fluid supplied from a pressure fluid supply source is small, the pressure fluid passes through the small hole 43b to flow in the low-pressure portion 45. Thus, the pressure on low pressure side amounts to a designated value earlier, and after that, the pressure on high pressure side amounts to a designated value. Accordingly, even if the speed is changed from the low speed of an engine, the pressure on low pressure side amounts to a designated value earlier than the pressure on high pressure side to secure designated side pressure, so that transmission loss during the above period can be reduced.

IPC: G11B5/39
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To reduce Barkhausen noise. SOLUTION: A longitudinal bias layer 8 of α-Fe2 O3 (iron oxide) is allowed to adhere to the bottom of a magnetoresistance layer 4. The bias layer 8 not only applies an exchange anisotropic magnetic field to the magnetoresistance layer 4 but also imparts such high coercive force as about several hundred Oe to the magneto-resistance layer 4 in a region B. Since the magnetization of the magnetoresistance layer 4 in the region B in a direction (x) is stabilized and a sure longitudinal bias magnetic field is applied to the magnetoresistance layer 4 in a region A, Barkhausen noise can be reduced and magnetic detectability can be improved.

IPC: G21K1/00
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to generate good-quality slow positron beams by increasing the efficiency in the extraction of them. SOLUTION: White positrons generated from a positron source 1 are incident on a positron moderator 2, which emits slow positrons. The slow positrons at once emitted again and generated around the center of a positron moderator 2 are accelerated in the direction of the positron source 1 by the potential difference applied between the positron source 1 and the positron moderator 2, focusing on the center axis by the effect of a magnetic field formed by a coil 3. Then, these slow positrons pass through a through hole 1e at the center of the positron source 1 and are outputted as positron beams with a prescribed energy.

Title: Route guidance device for vehicle
Inventor: FUJIMOTO HIROSHI
IPC: G01C21/00
Filed: 1994-09-12
Abstract: PURPOSE: To confirm an advancing direction at a crossing without disturbing visibility. CONSTITUTION: Concerning the route guiding device for displaying a guidance route to the destination on an HUD projector, while the distance to the target crossing is still long, only the advancing direction due to an arrow or the like is displayed at a position D' away from the front side of a driver but when the vehicle gets close to the target crossing gradually, the display position is moved adjacently to the front side like D and an image overlapping the shape of the road (crossing) and the advancing direction is displayed. Further, when the vehicle is just close to the crossing, the advancing direction is displayed at a position C on the front side.  Since the image is first offset to right and left and displayed later, the visibility of the forescene is not disturbed and further, since only the advancing direction is instructed while confirming the existence of the HUD display image with peripheral viewing at the moment when that image is displayed on the left or right side, no trouble is felt. Then, since the image is gradually moved to the front side, the distance to the target crossing can be naturally recognized by the position change of the HUD display image.

Title: Drum brake with automatic shoe gap adjusting mechanism
Inventor: SUZUKAWA SHOICHI
IPC: F16D65/54
Filed: 1994-10-07
Abstract: PURPOSE: To provide a drum brake which is constituted to stably block operation of an automatic shoe gap adjusting mechanism when the press force of a brake shoe is increased to an excessive value. CONSTITUTION: An engagement releasing device 64 releases the pawl part 56 of an adjusting member 52 and a star wheel 36 from an engagement state therebetween through deformation when the increase of a drum brake temperature occurs. Since the engagement release device 64 is attached to a first engaging member 38, when the increase of a drum brake temperature occurs simultaneously with the increase of the inside diameter of a rotary drum as a result of the press force of a brake shoe being increased to an excessive value, operation of an automatic shoe gap adjusting mechanism is reliably blocked.  In this case, since a slide protrusion surface 66 is deformed in such a manner that it is positioned closer to the outer peripheral side than a cylinder surface along the cylinder surface pressing the outer peripheral surface thereof, the pawl part 56 is reliably separated through small deformation. This constitution decreases a deformation amount of the adjusting member 52 and suitably suppresses the generation of an excessive load and performs stable blocking of automatic shoe gap adjustment.
