Title: Photo detector with film reflector
Inventor: SO BERNARD Y C
IPC: G08B17/107
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To improve the S/N ratio and the performance by using, as reflector, a reflection area, which is formed out of a cylindrical chromium layer on the internal surface of a housing and covered with a reflection material. SOLUTION: Radiation energy from a laser light source is admitted into a housing 12 via a radiation energy input part 14. All the incident non-scattered energy 26 is absorbed by a light trap 22 having an internal light absorption area 24 in an internal capacity. In this process, smoke particles flowing into the internal capacity 16 together with air passing through openings 20a -20n provided in the wall of the housing 12 cause a forward scattering as scattered light 32a , 32b and 32c . The forward scattered light is reflected by reflection areas 12c and 12d , which are formed out of a cylindrical chromium layer on the internal surface of the housing 12 and covered with a reflection material to be collected by a photosensor 29 at an end of a conical area 12b . The output of the photosensor 29 provides an index for incident scattered light.  Thus, the use of the reflector formed in the reflection area inside can improve the S/N ratio thereby increasing the level of a signal with respect to the phtosensor 29.

Title: Car height adjuster by hydraulic buffer
Inventor: NAKAZATO KAZUO
IPC: B60G17/00
Filed: 1983-02-15
Abstract: PURPOSE:To improve accuracy of car height adjusting by fixing a lower spring seat travelably through a hydraulic jack to hydraulic buffer and remote operating the hydraulic jack. CONSTITUTION:Upon forward rotation of reversible hydraulic pump not shown, oil is fed to a hydraulic jack 4 to move a jack piston 9 up and down. Consequently an integrated lower spring seat 3 is pushed up to increase the car height. Here the oil feed pressure corresponding to the car height sate is detected by a pressure switch not shown to stop the pump. When rotating the pump reversibly to discharge oil from the jack 4, the car height is lowered. With such arrangement, car height can be adjusted simply and correctly.

Title: Charged particle beam irradiator
Inventor: GAMA ETSUTORA
IPC: G21K5/04
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To make it possible to measure the dose of a charged particle beam accurately without affecting the flow of the charged particle beam under normal conditions by revolving a shield on a specified axis in synchronization with the drive control of the deflection of the charged particle beam. SOLUTION: A charged particle beam 1 that has been incident is revolved on a specified axis and is scanned like a charged particle beam 5 by deflecting electromagnets 2 and 3. The charged particle beam 5 passes through a slit 21a of a shield 21 that is revolved in synchronization with the deflecting electromagnets 2 and 3, is scattered by being irradiated with a scatterer 7 and forms a required irradiated field 9 on an irradiated surface 8 as an expanded charged particle beam 10. On this occasion, the charged particle beam 5 passes through the slit 21a without suffering interference, so that the charged particle beam 5 does not stagnate in the shield 21. Therefore, an electric current does not flow from a brush put in contact with the side face of the shield 21.  The measurement of the electric current makes it possible to judge whether a position where the charged particle beam 1 is incident, the operation of the electromagnets 2 and 3 and the like are normal or abnormal.

Then a bob 6 having a specified weight is hooked at the tip of the test piece which is suspended vertically. Under this state, a current which is 60% of the fusing current for the wire material is conducted for 30 seconds. After the first heat treatment, the bob 6 is removed. Then, the test piece 3 is horizontally held in a cantilever state. Under this state, a current which is 90% of the fusing current of the wire material is conducted again for 300 seconds, and the second heat treatment is performed. The amounts of deformation from the horizontal position of the free end of the test piece before and after the second heat treatment measured. The amount of the deformation is compared with the wire material, and the vibration resistance characteristic of the wire material is evaluated.

IPC: A47L13/60
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To easily switch a non-using state and a using state by a switching lever by interposing a repulsive pressurization mechanism for clamping a mop exceeding a dead center. SOLUTION: A point where the track F of a shaft center C and a plane E are crossed becomes the dead center D of the repulsive pressurization mechanism 4 and the repulsive pressurization mechanism 4 is turned to the state of exceeding the dead center D downwards in the using state of clamping the mop 32. Then, at the time of exceeding the dead center D downwards, since an elastic body 12 pressurizes a rotary arm 13 downwards, the rotary arm 13 is formed so as to be locked to a front locking part 22 attached to a main body frame 7 so as not to be swung downwards more than needed. Since the switching lever 3 is pressurized downwards at all times, it is held in a forward tilting posture without being swung upwards.  Also, on the other hand, when the repulsive pressurization mechanism 4 exceeds the dead center D upwards, since the elastic body 12 pressurizes the rotary arm 13 upwards, the switching lever 3 is swung upwards.

Abstract: PURPOSE:To prevent a document from damaging and to improve the safety and reliability by providing a detecting means which detects whether or not there is the document at an exposure position and a control means which controls an automatic document feeder to discharge the document when the detecting means detects the presence of the document. CONSTITUTION:When the document D2 is mounted on an original platen 30 manually or removed from the original platen 30, a switch 31a detects a document cover 32 being opened and closed. The detection result is sent to the 1st controller 53 of the automatic document feeder 3 and when the opening/ closing operation of the document cover 32 is detected after copying operation, the automatic document feeder 3 feeds the document D1, but when the opening/ closing operation of the document cover 32 is not detected, the 1st controller 53 inhibits a pickup roller 36 from performing taking-out operation, so that the automatic document feeder 3 is inhibited from feeding the document D1. Consequently, the document is prevented from damaging and jamming and the reliability and safety of the device are improved greatly.

Filed: 1989-02-01
Abstract: PURPOSE:To improve out of focus caused by a deviation in range-finding parallax by dividing light projecting and photoreceiving optical paths and sharing pointing directions to the divided optical paths respectively. CONSTITUTION:The optical paths are divided into two groups by forming a part of a visible ray cut-off filter 61 arranged on the front planes of the light projecting and photoreceiving lenses 9 and 11 into a cleat shape. The optical paths of one group are constituted so that they intersect with a photographing optical axis in such ordinary object distances as 2m and 3m, and the optical paths of the other group are constituted so that they intersect with the photographing optical axis near photographing-enable closest distance, for example in 0.6m. Preferably, the optical paths of the latter group are constituted so that power passing them is several percent - several tens of percent of power passing the ordinary optical paths of the former group. The out of focus caused by the deviation in range-finding parallax in a close distance is improved and degradation in performance in other object distances is eliminated.
