Title: Ttl finder optical system
Inventor: OSAWA TAKAYUKI
IPC: G02B25/00
Filed: 1997-08-09
Abstract: PROBLEM TO BE SOLVED: To obtain high finder magnification at low cost even when the focal distance of a photographing optical system functioning as an objective lens is short and an image inversion system exists in the optical path of a finder ocular optical system between a real image forming surface and a pupil surface. SOLUTION: In the finder ocular optical system G2; a principal point position is thrusted forward by arranging a positive lens group F1 → a negative lens group F2 in this order from an image surface side to the pupil surface in order to make the real length of the optical path long. The positive lens group F1 is constituted by using a thick positive meniscus lens L10 and a convex lens L11, a principal point interval is extended, and the entire length of the lens is made longer without changing the focal distance of the entire optical system. The 1st surface on an object side of the lens L10 near the real image surface of the positive lens group F1 is made concave to the object side. The negative lens group F2 is constituted of two lenses, that is, a positive meniscus lens L12 and a negative meniscus lens L13.  By moving the lens L13 in an optical axis direction, the diopter of a finder is corrected.

Title: Feed water tank
Inventor: HIRAYAMA KENICHI
IPC: F24F6/04
Filed: 1985-10-12
Abstract: PURPOSE:To make it possible to supply a great quantity of water with a single switching of a solenoid valve, by providing a flowing out part of water toward the side of a float switch at a part higher than a water level at which the float switch opens the circuit, providing also a partition plate having a flow passage at the lower part thereof which allows a flow rate of water smaller than that of feed water through a water supply pipe. CONSTITUTION:A partition plate 24 is provided on the side of a float switch 5 and the flow rate of water passing through a flow passage 24b is smaller than that of feed water supplied through a water supply pipe 2, so that the rising speed of water level on the side of said float switch 5 is smaller than that on the side of the water supply pipe 2; as a result the water level on the side of said water supply pipe 2 rises earlier, causing feed water to flow from a flow out part 24a, provided at a part higher than a water level B at which the float switch 5 opens the circuit, to the side of the float switch 5. In the manner as stated above, when the water level A on the side of the float switch 5 reaches a predetermined level B, the float switch 5 opens the circuit to stop the supply of water. As the device works as stated above, a large quantity of water can be supplied to a feed water tank by a single switching of the electromagnetic valve.

Title: Electron beam exposure method
Inventor: NAKASUJI MAMORU
IPC: H01L21/027
Filed: 1984-10-29
Abstract: PURPOSE:To reduce the influence of proximity effect caused by the difference in the back-scattering coefficient of the base as well as to enable to contrive improvement in the accuracy of exposure by a method wherein a beam is supplementary made to irradiate on the region having a small back-scattering coefficient. CONSTITUTION:The pattern in the region having no Mo becomes thin as shown by the dotted line in the diagram when a patterning is performed on the expected pattern forming region 12 in the same manner as the ordinary exposure. This is because the reflected electron coefficient of the base differs by the presence or non-presence of Mo in the base, the coefficient of back-scattering is differentiated in proportion to the above-mentioned difference, and a dosage becomes short in the amount of reduction in the back-scattering in the region having no Mo. At this time, an obscure beam is supprimentary made to irradiate on the region having no pattern to be formed and also having no Mo. As a result, the thickening of thinning of pattern can be prevented, and the pattern almost equal to the pattern on the exposed pattern forming region 21 can be formed. This is because the quantity of the back-scattering electron in the region containing no Mo in the base and having a small back-area scattering no Mo in the base and having a large back-scattering coefficient.

Inventor: ADACHI TATSUYA
IPC: G01N23/225
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To obtain a method for observing the cross-section machining image of a sample subjected to trenching in which the surface image of a sample formed by secondary electrons being emitted from the sample upon irradiation with an ion beam and the cross-section machining image of secondary electron on the side face of a trench made in an arbitrary specified region by means of an ion beam can be displayed and observed instantaneously while being switched by a switch.

The ion beam scans the sample to emit secondary electrons or to enhance the intensity or the acceleration voltage thus trenching an arbitrary specified irradiating region of the sample by sputtering. A beam switch 13 switches the ion beam irradiation system and the electron beam irradiation system alternately and an image display displays the output from a detector 6 as the surface image of the sample or the cross-section machining image on the side face of the trench depending on the switching operation of the switch 13.

Title: Rotary transformer for magnetic recording and reproducing device
Inventor: SASAKI YOSHIYUKI
IPC: G11B5/02
Filed: 1983-11-30
Abstract: PURPOSE:To enlarge effective area of an air gap, to enlarge combination inductance and to enlarge coupling coefficient by forming opposing face of a fixed side core and a rotary side core to intersect obliquely to a plane that intersects the rotation axis at right angles. CONSTITUTION:An opposing face of the rotary side core 1 and fixed side core 3 is formed to intersect obliquely to a plane that intersects the rotation axis that rotates a rotary head at right angles. Accordingly, the area S of air gap can be made large. Consequently, combination inductance which is in proportional relation with the area of air gap can also be made large, and coupling coefficient becomes large. When the center axis is deviated within an extent that does not cause contact of respective opposing faces of the rotary side core 1 and fixed side core 3, the length lg1 of air gap to which opposing faces draw near becomes shorter than the case in which the center axis conforms correctly. On the other hand, the length lg2 of air gap from which the opposing faces separate becomes longer. Accordingly, change of combination inductance and change of coupling coefficient offset each other, and consequently, the change can be reduced.
