Inventor: UENOSONO NORIAKI
IPC: H01L21/683
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To provide a substrate cleaning method and an apparatus, in which the face of a substrate can be cleaned uniformly, and in which a foreign material can be removed without being restuck. SOLUTION: Every substrate 1 to be cleaned is set at an angle θat which the removal rate of a foreign material is highest with reference to a chemical liquid 3. The angle θ can be changed by every angle adjusting device 4. When every ON-OFF valve 5 which is installed at a pipe connected to every nozzle 2 is turned on and off by a control signal from a controller 6, the chemical liquid 3 is dropped onto every substrate 1 by every nozzle 2 so as to be wavy on the surface of every substrate 1, and the foreign material can be removed surely due to surface tension.

Abstract: PURPOSE:To record the contents of the signals received by a signal reception unit onto a recording material having a good preservable property by delivering a thermosensitive recording material on which the contents of the received signals are recorded by a signal reception unit as a document onto the document platen of the device body and recording this document in enlargement onto the recording material by an image forming means. CONSTITUTION:The information which is the image contents of the facsimile document transmitted to a signal reception side is scanned by signal reception scanning and is outputted as the signal reception contents. This information is charged to the signal reception unit 20, by which, for example, a plate size is reduced to A6 (post card size). The information is printed and recorded on heat sensitive roll paper 31 via a platen roller 32 and a thermal head 33. The macroreading (A6 A4-R) on a copying reference position B side on a right side is executed by the image forming means consisting of a document reading mechanism 4a. The information is thus formed as an electrostatic latent image on a photosensitive drum 4b of the image forming means 4 and is copied and recorded on plain paper (A4-R)P fed to the device body 1; thereafter, the paper is discharged to the outside of the device body 1.

Power supply is performed for the power supply means 110 to start charging the power supply means 110. As charging current, a current value higher than ordinary charging current is selected by a shifting means 109.  It is thus possible to significantly-improve power supply efficiency at the time of intermittent charging and significantly-reduce required electric power averaged at standby.

IPC: G01C3/06
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent a range-finding feasible range by auxiliary light from being reduced even in the case the power source voltage falls down. SOLUTION: In the case the AF auxiliary light is required, a control circuit 13 measures the voltage V of a battery E by using a voltage detection circuit 14 so as to confirm the battery voltage. When the battery voltage V is equal to or under specified voltage Va, the maximum value of the operation time of an AF sensor 10 is changed to a larger value than an initialized value. Then, a distance from a subject is arithmetically calculated according to information on a subject image obtained by emitting the AF auxiliary light from a light emitting element 71 and receiving the reflected light of the auxiliary light reflected from a subject by using the AF sensor 10 during the time of the maximum value of the operation time after the change.  In the case the power source voltage becomes low and the quantity of the AF auxiliary light becomes small, the operation time of the AF sensor 10 is made longer so that the range from the subject by the AF auxiliary light may not be reduced.

Title: Joint working machine and joint working method
Inventor: AKAMATSU TATSUYA
IPC: B27F1/00
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a joint working machine and a joint working method, with which working operation requires no laor and working at the adjustment of the fitting condition between a tenon and a mortise is easily performed without requiring skillful technique and the improvement of operation efficiency is contrived. SOLUTION: In case of tenening, a tenon K is formed in a wood W1 by rectilinearly moving (as whown with the arrows 90 and 91) a rotator 3 and turning (as whown with the arrows 98 and 99) a cutter 60. In addition, in case of mortising, first of all, the rotator 3 is rotated by 90 deg. so as to position the cutter 60 on a center line 50. A mortise H is formed in the wood W1 by rectilinearly moving the rotator under the above-mentioned state of the cutter. Thus, the setting of the wood W1 to the saw installation position P1 is enough even either in case of tenoning or in case of mortising.  Further, since even when the fitting condition between the tenon and the mortise mortise is adjusted by increasing or decreasing the turning radius of the cutter 60 by the adjustive amount Δx on the rotator 3 and the mortising can be performed by positioning the cutter 60 on the center line 50, as for the mortise H, the adjustive amount Δx is only reflected to the direction of the depth and consequently the movement of the rotator 3 by the standard depth is enough.

Therefore, the entire light emitting part 1 is held by the supporting part 25 and the supporting shaft 21 so that it can be turned with respect to the base 2. An L-shaped long hole communicating with a hole in which the supporting shaft 21 is fit is formed at the supporting part 25, and the supporting part 25 is formed so that its cross-sectional area may be partially small by the edge part of the long hole.  Therefore, when strong impact force is exerted on the light emitting part 1 due to dropping, etc., stress is concentrated at the part having the small cross-sectional area of the supporting part 25, which is deformed and folded, so that the impact force exerted on the light emitting part 1 is softened.
