Title: Cam grinding method
Inventor: NAKAJIMA FUSAO
IPC: B24B19/12
Filed: 1985-05-27
Abstract: PURPOSE:To grind a cam block so accurately without entailing any drop in a revolving speed or an infeed rate of a grindstone as well as to make improvements in operation efficiency, by separating the grindstone from the cam block for a moment during grinding the cam block. CONSTITUTION:When a cam shaft W is once twisted in grinding operation on a cam block Wa, restoration of this cam shaft W is prevented by a grindstone 1 even if cutting resistance is decreased by an advance of grinding. But, when the grindstone 1 in grinding operation is separated from the cam block Wa for a moment, the camshaft W is restored whereby the cam block returns to its regular phase, and in this state, subsequent grinding takes place, so that a slip in its phase at completion of grinding of the cam block is reduced as much as possible. Thus, since the cam block Wa is grindable without entailing any drop in a revolving speed and a infeed rate of the grindstone, operation efficiency is improved.

Title: Judging method for clogging of application nozzle
Inventor: NAGAMOTO MASAO
IPC: G01B11/28
Filed: 1990-04-27
Abstract: PURPOSE:To judge whether or not a nozzle is clogged in a wide range of the state from where an applied pattern is not present at all to where the applied amount of the pattern is insufficient even if the number of the applied patterns is changed by measuring the sum of the area of a plurality of the applied patterns through image processing and comparing the sum with a reference value. CONSTITUTION:An applied pattern 3 on a circuit substrate 2 illuminated by an illuminating device 1 is photographed by a camera 4. When an image taken by the camera 4 is processed by an image processor 5, it is detected whether an application nozzle is clogged. In other words, the presence or absence of the applied pattern is detected first. Thereafter, the size of the applied pattern is measured and compared with a reference size. Moreover, if the applied amount is insufficient although the applied pattern by each nozzle is present, the individual area of each applied pattern is compared with a reference value. Accordingly, it becomes possible to judge a plurality of nozzles as to whether they are clogged.

Title: Elevator hydraulic jack
Inventor: FUJITA HIFUMI
IPC: B66F3/24
Filed: 1988-05-12
Abstract: PURPOSE:To minimize the phenomenon of compression of hydraulic oil and affection by expansion of hydraulic coil due to a temperature rise by setting a play margin from a flange cut-out area to the inner wall surface of a cylinder to be larger than a play margin from a flange part area to the inner wall surface of the cylinder. CONSTITUTION:Since large and small play margins G1, G2 are defined in a cylinder 3 by a flange part 25 of a plunger 5 and a flange cut-out part 23, the inner diameter of the cylinder 3 may be reduced, resulting in a decrease in the amount of hydraulic oil. Accordingly, in such a case that the flange part 25 abuts against the inner wall surface 3a due to an error in installation of the hydraulic jack or the like, the plunger 5 is rotated by a predetermined amount so as to allow the flange cut-out part 23 having a larger play margin to confront the abutting position, and accordingly, a desired clearance may be obtained between the plunger and the inner wall surfaces 3a. With this arrangement, during ascent or descent of the plunger 5, it is possible to minimize the phenomenon of compression of hydraulic oil, affection by the expansion of hydraulic oil due to a temperature rise and the like. Further, a cage may be stopped at a substantially regular position on an arrival floor, thereby it is possible to eliminate anxiety and uncomfortness.
